Chapter 759
Collected fingerprints are divided into three categories, obvious lines, formed lines and latent fingerprints. The former two are visible to the naked eye, while the latter are not visible and require some processing to see the original appearance and extract it.This type of latent fingerprint is the most prevalent in common crime scenes.
There are many ways to collect this kind of fingerprints, such as powder method and magnetic powder method. The former is attached with powder with different colors, and the latter is attached with iron powder, and then the fingerprint can be displayed by swiping with a magnet. The most widely used is the powder method.In addition, if fingerprints are left on the surface of paper, cards, leather, wood and other absorbent items, they must be chemically treated before they can be visualized and extracted.
There are also many chemical methods, such as iodine fumigation, Ninghai Delin, silver nitrate method, fluorescent reagent method and so on.
Materials are needed to do all of these, and there is also a device that can clearly scan and record visible fingerprints into a computer. The combination of the two is fingerprint extraction.The next comparison is to mark the feature points on the fingerprints in the fingerprint library of the public security system, plus the auxiliary screening of the program, and patiently look at them one by one.
In the current situation, there are still very few people whose fingerprints are not in Curry.Fingerprints are required to apply for an ID card, and fingerprints are required to punch in at work. Internet cafes can also use fingerprints instead of ID cards to surf the Internet. In the past two years, facial recognition has begun to be directly connected to the public security system.
As Wang Shouyi said, the things used to extract fingerprints are not expensive, but it is difficult to find all of them for a while.On the other hand, even if you don't have much money, you can definitely spend your own money without spending your own money. The funds in the institute are so tight, let alone tens of thousands, it's [-], which should take advantage of it. have to account for.
Team Luo had already called. Wang Yan and Gao Chao arrived at the place. He had prepared a large box of materials and tools, and he was quite happy.Now someone in the lower-level police station will take fingerprints for comparison, and their work will be much less. After all, it is a jurisdiction with more than 12 people.
But in fact, nothing has changed, it's just that they relax in their hearts.When there was the Balihe police station, they were as busy as dogs, and when there was no Balihe police station, they were also like dogs, it's all the same.It's just that one less person from the police station came to remind me. Although it didn't have a big impact, it was always a little cleaner.
Just like that, driving with a lot of stuff, Wang Yan and Gao Chao found a nice restaurant outside for a bite of food, and then went all the way back to the institute.
"Today, the office has provided desks for you guys. Now, this one is yours."
Gao Chao smiled and helped Wang Yan carry things, and moved to a new desk.He said, "Speaking of which, you earned it yourself. Otherwise, if you want to have a desk and a computer, you will have to wait for two months. It is because your image has been enhanced recently, and the detection rate of our firm has soared, so It is much more convenient for Chang and Bureau Song to ask for funds. Once your fingerprint comparison is done, then we will be able to stand up completely. Image enhancement with one hand and fingerprint comparison with the other, ordinary cases can be solved at least [-]% of the time."
This is opposite to four desks, and another one is opposite to Cao Jianjun's desk, Yang Shu is sitting there, and the remaining four Wang Yan are together.
Wang Yan said with a smile: "It's not that easy. Although there are always shows on TV, people's awareness of protecting the scene is still relatively low. We can only say that we should do our best."
"Just solve as many cases as possible. Just like the thief this time, I guess, he probably didn't wear gloves. Think about it, it's been three years, and he didn't steal [-]. He just wore gloves at the beginning." Yes, after three years, you have been slack, and you are likely to solve the case directly this time."
"Let's take out the fingerprints first and have a look."
"You are too conservative." Gao Chao smiled and pointed at Wang Yan, then waved his hand, "Okay, you can do it yourself, and you can find me if you have anything to do."
After all, Gao Chao greeted people with a smile, and left for the crime scene in Dongning Village...
As soon as the climax left, Wang Yan was surrounded, not only Li Dawei, Yang Shu, Xia Jie, but also old police officers such as Chen Xincheng, and even two prosecutors who were cooperating in the office came over. .
Li Dawei asked: "I heard that there was a murder case in Dongning Village? What happened at the scene? Tell us about it?"
Gossip is human nature, and the police are no exception.In today's society, it is not easy to encounter a murder case, let alone a murder and dismemberment case that is happening in one's own jurisdiction.I want to ask what's going on, and listen to the excitement.
From this direction, the gang of policemen in the Balihe Police Station is no different from the crowd in Dongning village who are blocking the cordon to discuss.
But this also made Dong Nianfeng's impulsiveness even more sad.
Wang Yan looked at Yang Shu: "Can you say it? I remember we are disciplined, right?"
Yang Shu nodded, and said very strictly: "If the case is not closed, we cannot reveal the details of the case, let alone spread it to the people."
"Oh, how can there be so many things? The suspects have been caught. We will know about it sooner or later. It doesn't matter. Look, the big guys are waiting." Li Dawei didn't care, and the others didn't care. not give a damn about.
Of course, Wang Yan didn't care too much. The people who watched the scene had already explained the case clearly, and the whole Ping'an City, which would be able to spread it tomorrow, knew it all.
He laughed and said: "The suspect, the ex-wife cheated on him, caught him in bed, and beat the adulterer half to death... Later, it was found that the child was not his... The scene was quite bloody, the heads of the man and the woman were all used The ax was chopped off, and the woman's arm was also chopped off. The method was relatively rough, and the minced meat was all over the floor, and the blood was sprayed on the ceiling. In addition, there were many open wounds on the two deceased. Suffered a very painful torture..."
"Honest man, who did you provoke?"
"It was the same last year, when I went out to the scene, I cut off one of his hands..."
"I guess it's time for the director to hold a meeting for us. If there is such a police situation in the future, we must pay attention to it."
After hearing the process, especially the bloody crime scene, people said some words of congratulations to Wang Yan, and then dispersed.If there is a murder case, there must be credit.Combined with the soaring detection rate in the past two days, Wang Yan must at least be a commendation.If they had gone earlier, the two victims were still alive, and they were rescued in the end, and the suspect was successfully subdued.
Although they are immoral adulterers and whores, no one takes them seriously, they are 'victims' to the police.
"Have you vomited? I called Jiwei. That kid was sickly and frighteningly pale. When he was talking, he retched just thinking about the scene." Seeing that everyone had dispersed, Li Dawei asked curiously road.
"Do you think I'm throwing up? The big bone in sauce that I ate with Lao Gao just now is very delicious. Let's try it together some other day. The boss's craftsmanship is very good."
"Ugh..." Xia Jie covered her mouth in embarrassment, and hurried out to get some air.
This thing is afraid of thinking, even if Wang Yan's words are dry, the woman with a clever mind can render it into a vivid picture.Pools of blood, minced flesh, and decapitated heads are still scary to think about.
Xia Jie herself has some psychological problems, but she is not afraid of blood, but the feeling of close contact with death, which reminds her of her sacrificed father.She has been resisting, but she still doesn't want to do household registration work, she still wants to make a breakthrough.But her mother didn't give her this chance, and annoyed everyone in the institute, so she reluctantly went to do the household registration work.
This is really impossible, because if everything is treated reasonably, Wang Shouyi, Cheng Suo and others will not allow her to participate in dangerous work, and there is a mother who is a demon at home.
Li Dawei didn't feel very good either, so he took a sip of water tactically to suppress it, and asked curiously: "What's the matter, brother Yan, I heard what Gao Suo said, can you still compare fingerprints?"
"Easy ones can be right, too difficult ones can't." Wang Yan nodded with a smile, opened the box he brought back, and took out various materials from it, as well as the bank card he brought back from the victim's house and several doorknobs. .
"I'm really convinced now. I can enhance images and compare fingerprints. No wonder the director smiles when he sees you. If I were him, I would smile too. Based on these two things, you will be indispensable in the future. Brother Yan, Can you pass it on to me when you have time? I want to learn too."
Wang Yan nodded with a smile, picked up a pen and paper and wrote a bunch of words flamboyantly, tore it off and handed it to Li Dawei: "Come to me after reading all these."
"I don't care. Do you need to read so many books for image enhancement and fingerprint comparison? Eleven books and dozens of papers?"
"This is the basics. After reading these books, general image enhancement and simple fingerprint comparison, as long as you practice in a targeted manner for a month, you can basically handle the most basic ones. There are no tricks in technology, only a lot of related Knowledge reserve and practice can be applied. I just teach you, you don’t understand.”
"Yang Shu, if you are interested, you can learn it." Li Dawei casually photographed the book list on Yang Shu's desk, "Then what, you are busy, Brother Yan, I still have a lot of work in hand Well, finish it early and be quick."
"Look at Brother Chen's eyes." Wang Yan waved his head in Chen Xincheng's direction.
Li Dawei spoke so loudly that everyone in the institute heard their conversation.Chen Xincheng was staring at Li Dawei with a look of helplessness.
"If you don't want to read and study, then you should work quickly and don't disturb everyone's work."
"I also want to improve..."
Even though he was chanting, Li Dawei quietly ran to sit diagonally across from Wang Yan and continued to do paper work.
After sweeping around the busy people in the office, Wang Yan sat there turning on the computer and fiddling with various tools.
Regarding his possible meritorious service, most of the people in the institute congratulated him casually and seemed to be happy. Only Cao Jianjun, who was sitting not far behind him, had a rather unsightly expression.
A young man who has only been here for not even a week, was lucky enough to bump into the murder scene, and he felt a little unbalanced.After all, he also wants to make meritorious service. He is actually more reckless than Li Dawei and Zhao Jiwei.
At this time, Xia Jie, who had been out for a while, also came back. Her desk was next to Wang Yan, opposite to Li Dawei, and next to Li Dawei was Zhao Jiwei.
Seeing Wang Yan fiddling with bottles and cans, Xia Jie asked curiously, "You really know how to compare fingerprints?"
"Look at what you said, can there be any fakes? This bunch of things are all sent by the director and the bureau." Wang Yan's smiling face Xia Jie said, "Are you okay?"
"Well, it's okay. It's just that I feel a little uncomfortable thinking about that scene. It's alright, don't talk about it, I'm thinking about it again." Xia Jie waved her hands again and again, and drank water quickly.
"Is it because of your father's influence that you have trouble in your heart?"
"It's nothing, just work, there are a lot of cases waiting to be settled."
Seeing Xia Jie working seriously, Wang Yan shook his head and continued to work.
First, all the fingerprints on the bank card are swiped out and scanned into the computer.Then, he scanned the fingerprints on the doorknob of the house into the computer together.In fact, this matter is still very difficult, because the fingerprint may be covered, and separating the fingerprint is a very professional and difficult operation.
But Wang Yan will also. He has always learned the key to learning things. It is practical to separate fingerprints, and he will definitely not be left behind.Whether the separated fingerprints can still be used is another matter. In this area, he is only proficient, not proficient.That's why he bought so many things and came back to scan his fingerprints. If there are too many things, the chances are great.
This thing is also a meticulous job, and Wang Yan's movements are not very skilled. After two hours of fiddling, he scanned all the fingerprints of the bank card and a doorknob, and officially started the fingerprint comparison.
Fingerprint comparison involves a lot of professional knowledge. No two people in the world have the same fingerprint. This difference is the same to ordinary people. Only professional people can see the difference. These differences are reflected in the subtle, over the bucket.
There are many fingerprint analysis methods, which have become a set of specific methods as early as the nineteenth century, and all countries in the world have learned and improved them.Wang Yan's meeting is very complicated. Anyway, no matter what the method is, the last thing is to mark the difference in characteristics and compare the fingerprints. If it can be matched, it will be no problem.
After asking for authorization, Wang Yan enhanced the fingerprints, and then pulled them into the fingerprint system to start comparison.
This thing is not difficult for the participants. More than ten characteristic points are marked, and the system automatically screens similar fingerprints according to the characteristics. It is useless for 10 minutes. First, the fingerprints of the stolen elder brother's family of three are excluded. .After excluding the three of them, the rest is difficult.
He successively found the fingerprints of the worker who changed the door, the previous tenant, the bank manager, and the teller. Wang Yan had already collected the information when he chatted with the older brother.The elder brother's house was attacked by thieves, suspicious, and the two original tenants were suspiciously taken away. That's why when he went, he caught up with the new tenant who didn't have a residence permit.
In addition to these, there are even two relatives of the elder brother, who called the elder brother to confirm at night.Eliminate all these, and work hard on the remaining strange fingerprint.
In fact, the workload is not that big, because it has been judged that the suspect who has committed theft more than ten times and nearly twenty times for three years in a row is from Dongning Village.
Migrant workers, even if they have come to work in Pingan City for three consecutive years, it is basically impossible for them to live in Dongning Village for three consecutive years. Their mobility is too great.For villages like Dongning Village, there are several villages in Ping'an City except for the south facing the sea, east, west and north.
So this further narrowed the scope, that is, the household registration personnel of Dongning Village sit in the local household.Then Wang Yan had to do a lot less work of comparing fingerprints. There were only a few thousand people in total, and there was a rough screening system, so there was not much workload.
Wang Shouyi, who did the logistics work for the comrades in the institute, did not come back, and neither did Zhang Zhijie. It is estimated that both of them were affected.The scene was indeed too bloody. When Dui Luo asked Wang Yan about the situation, the busy criminal police inside ran out and vomited several times.
Murder is not uncommon, social conflicts are great, and homicides still happen from time to time.But planned murder and dismemberment are relatively rare.If you don't hit the scene today, and wait until a few days later when other people find the body parts, Bureau Song will be the leader of the task force as soon as the report is received, and the case will be named 'June [-] Extraordinary murder and dismemberment case'.
If it is not broken within a certain period of time, then Team Luo will be transferred from the post of the head of the Criminal Police Brigade of the sub-bureau. Although Bureau Song will not be slapped, it is still a bit dangerous. Detective work...
Again, being a leader means taking responsibility, and luck is really an important factor in being a leader.
Wang Shouyi was old and couldn't bear the stimulation, so it was normal to stay at the scene for a while to help out and go home early to rest.
As for Zhang Zhijie, this old boy not only has to bear the impact of the brutal crime scene, but also has doubts about the community work he has done for 20 years.After all, in the past, Dong Nianfeng chatted with him very well, and he also showed new hope for a new life. He opened a small shop, studied fish every day, and occasionally went out to catch a fish or catch a sea. It was very comfortable.
But there was no sign of it. Today, such a boss came to him as a surprise. If he said kill, he would kill him. It would be strange if he could work hard.I also have to go back to my warm family, heal my wounds, and regroup before setting off.
So when it was almost ten o'clock in the evening, only the climax came back with the four policemen who had passed before.
After saying hello to the people who were still busy in the office, Gao Chao walked behind Wang Yan, leaned on the chair and looked at the magnified fingerprints on the computer, and asked, "How is it? Can you compare?"
"I just found an unknown person, I guess this is left by the thief. It's..."
After Wang Yan finished speaking, he leaned forward and got closer to the screen, comparing the two fingerprints from left to right.
Of course Gao Chao understood what this meant, so he didn't say a word, just looked at the fingerprints on the computer from behind, and quietly watched Wang Yan busy.Although he couldn't understand it, and even though his eyes were a little dazzled, he still insisted on watching.
If there is nothing wrong, this is a thief, he has a sense of participation...
Three to five minutes later, Wang Yan confirmed it carefully, "We have won the competition." While speaking, he clicked the mouse, and the page jumped, and the citizen information was displayed on the computer.
"If there is no accident, it should be this Liu Jialiang, 21 years old. However, it is still not sure whether this Liu Jialiang is, and I have to ask the elder brother again, how is their family's relationship with this Liu family? A lot. Lao Gao, do you want to catch him or not?"
"Needless to say, he is so conservative. His fingerprints are comparable. Isn't he the only one? That's almost the same. But this kid can't run away. The office is so busy, how can I have the time to take care of him and let him sleep well?" Think about it, and catch it tomorrow when you have time. Don’t participate this time, and you have to carry out community work in the future. It’s two different things if you catch it and if you don’t.”
Wang Yan shook his head and smiled: "I can't hide it, it's all the same. I chatted with the elder brother who reported the crime two months ago for more than an hour. If he is arrested tomorrow, the victim must be notified. Believe it or not, this I informed them that the case had been solved, and the elder brother would call me the next moment. The people in Dongning Village knew that I was the one who did the fingerprinting, and they couldn't help but look blankly."
"Hey, as long as you can accept it. When parents protect their children, and you do mass work, then you understand Long Live." Gao Chao patted Wang Yan's shoulder vigorously, "Okay, let's go back early when we're done with work."
"I'm really fine, Lao Gao. The office is so busy now. As a member of the group, I have to help share more work."
"Your boy is more suitable to be an official than me." Gao Chao patted Wang Yan amusedly, "You don't even have law enforcement qualifications, what kind of work can you share?"
"Hey, Gao Suo, that's not right." Liu Xianfeng who was not far away spoke. It was the policeman who brought Wang Yan to the police last night. He was in his 40s and looked sleepy. He was an ordinary middle-aged man.
He said: "This kid is really good at mediating disputes between husband and wife and neighbors. If you don't say that our king has a sharp eye, he knows that this kid is doing a good job with the masses. If this kid is willing to do it, then let him do it." How much work do you think we have done if you have the time to cut off housework for others? I am optimistic about you, work hard."
This old boy is saying good things, laying the groundwork, and preparing to pull Wang Yan into a coolie in the future.
The office is full of veterans, although the people are nice, but they are merciless when they catch young people around.At this point, any unit is the same, that is, bullying newcomers openly.
Wang Yan smiled, ignored him, and said to Gao Chao: "Old Gao, you have to help me, tell the director, let the director use the opportunity to work hard."
"That's for sure, it should be ours. Come on, if you don't want to leave, don't leave, follow the police, and learn more about on-site handling. In addition, I also have a few fingerprints that need to be compared. The case is under pressure, all in the last half a month, I asked the technicians of the branch office to scan the fingerprints, it should not be done yet, I will come over for you to have a look later."
"Okay." Wang Yan nodded in agreement.
It's the same as image enhancement technology, when he compares all the fingerprints in the institute, he doesn't have so much work.And as time passed, for about five or six or seven months, the number of similar cases that occurred in their Balihe district would definitely drop sharply.
Because it is human instinct to seek advantages and avoid disadvantages, there is also a circle for petty theft and petty criminals, and if they are caught hard here, they will naturally stop committing crimes here.The public security environment of the Bali River can be significantly improved.
Moreover, he is still doing community work at the same time, going out to visit during the day, so after five, six or seven months, he can basically visit the jurisdiction area with more than 12 people.With his observation and judgment, at least half of the bad guys in the crowd can be caught.That is another big change for law and order.
"Listen up guys, I guess our director will have to tell you when he comes tomorrow, so I'll talk about it first. I don't care about the cases that require fingerprint comparison in my hands. Let's see Wang Yan's speed. But For current cases in the future, if there is a need for fingerprint comparison, there is no need to go to the sub-bureau, let Wang Yan do it first, and then go to the sub-bureau if it can't be done."
Wang Yan also stood up: "Let me also say that, the comrades in our office should learn to extract fingerprints. Generally, simple fingerprints have no technical content, and most of the cases we face are of this kind. What kind of technology. After you have finished scanning, let me compare them, which is easier.
After a while, I will make a presentation file and send it to our group. Everyone can take a look at it when they have time.It is better to be able to collect in the first time, or to collect in the first time.Ugly speaking, don't try to save yourself trouble, call me every time to go to the scene to get fingerprints, once, twice or three times is no problem, there is a process of learning, but it is unreasonable to call me every time.I am a young man, so I should do more work and learn to improve, but I also know good and bad, and I have a little temper.
The technicians at the sub-bureau are the work they should do, and they provide us with technical support.But I am not, everyone must be clear about this.Otherwise, the young people don't know the importance, and I don't care about the collective honor during the meeting, and just curse people, that's not good.I was punished, everyone lost face, and it also affected unity.
So I hope that everyone can consider the feelings of our young people, don't fool around doing dirty work without thinking about it, playing with fools, and giving you big hats, it is unreasonable. "
Image enhancement is very easy to do. For ordinary images, he only needs to crackle for three to five minutes to solve the battle and call it a day.It is more difficult, it is not a matter of his technology, but a matter of computer configuration.More than ten minutes, twenty minutes, it is possible.
But fingerprint extraction is different. There are no technical requirements. It is the powder method to sprinkle powder, and use a small brush to swipe it for a while.Because there are often on-site fingerprint scanning requirements, it is impossible for one fingerprint, but one piece, so how long does he have to do it?
According to the behavior of these veterans, he can be sure that he will never learn fingerprint extraction at all.Compared to working hard on my own, how easy it is to make a phone call and kidnap righteously.
So he didn't give these people the chance to show their old status, and he didn't care about the so-called sophistication of the world.In the case of unequal situations, the so-called sophistication of the world is probably to put on a layer of cloak for being bullied by others, and also to find an excuse for comfort.In comparison, this situation is somewhat different from those who play rogues and take advantage of others, but there is no big difference. They have certain commonalities.
He has been amiable for several days, his ability has also been displayed, and his temper has to shine. Of course, this is based on his own conditions.
Normally speaking, when receiving a call from others, the excuse is that you are busy and don't have time.After going through this once, twice, or three times, everyone will know his rejection.Or hard and soft, to express your dissatisfaction from the side.
But after all, he is not really a young man who has just graduated and started working, nor is he a silly boy whose blood surges after being fooled by a few words.He didn't care what these people thought at all, he went straight up, whatever he liked.
And to be honest, these people were just unhappy for a while, and then they laughed again after a while, and everyone was in harmony.
Li Dawei, Yang Shu, and Xia Jie were all stunned, did they speak so bluntly?Still open the map cannon?How nice are you usually?Oh, by the way, he is rich, self-willed...
Gao Chao also froze for a moment, seeing the momentary embarrassment, he wittily activated his leadership skills: "Look at what you said, these old comrades in our office are just here to bully you young people? But you said This issue really needs to be taken seriously. It is our problem to use the technology, but we can’t just call you alone. Extracting fingerprints is not an easy job, and it is really impossible to do it all by pointing at you.
In this way, the presentation file you mentioned will be produced first, and I will talk to our director tomorrow.It is also good to learn more skills, because it can better solve problems for the people.But there is something wrong with your attitude, I have to criticize you. "
"Accept criticism." Wang Yan stood at attention, and then looked at the policemen and auxiliary policemen present with a smile, and said, "I did say something wrong, and I didn't consider it comprehensively. I apologize to everyone. I'm sorry, brothers. Don't be as acquainted with me."
Although he has always been majestic and upright, it does not prevent him from being disgusting.If you really want to talk about disgusting people, he is also very good.And he still started the group first, and this group of people didn't have a chance to say anything else.
Chen Xincheng is a good person. He resolved the embarrassment at the moment: "It's not a big deal. Although what you said is a little blunt, it's not rough. That's the way things are. Hurry up and make that demonstration, When you come across the scene later, you taught us a few times in the past, and our firm will be able to compare fingerprints by ourselves in the future. The speed of handling cases will be much faster, and the evaluation will be advanced, so our firm will also be ranked first, and everyone will benefit .”
When he said this, the others followed suit, all smiling and waving their hands, saying that it was not a big deal.He also said that it is a good thing for young people to have a temper. They like what they say.
They also remembered at this time, this kid is still a rich man, and the "low-key" scooter with more than 30 yuan is parked in the backyard, and Li Dawei also showed them the photo, the S200 with more than 8 million yuan Just parked in the underground garage to eat ashes, being a policeman is not enough to earn a living.
Either they are naive and really want to serve the people, or they are rushing to climb up, they should not make trouble for themselves.They all knew that Wang Yan didn't mean to talk, and if he dared to scold them in a hurry, they were not used to it, and they were not afraid of punishment, let alone losing their jobs.And the ability is indeed strong, and the luck is also good. If it weren't for their senior qualifications, it might not be certain who will lead whom.
Only Cao Jianjun looked uncomfortable, but he didn't say anything...
As if nothing had happened, Gao Chao left with a yawn. Everyone was busy, but it was still lively. Li Dawei took Wang Yan out to smoke, and Yang Shu and Xia Jie followed.
"Brother Yan, you will be my real brother from now on." Li Dawei clasped his hands together and took out a lighter from his pocket to light a cigarette for Wang Yan.
Xia Jie hesitated and said: "I don't think this is good. You said it so directly, how will everyone get along with each other in the future? Besides, our director pays most attention to collective honor and unity. He will definitely scold you when he comes tomorrow morning."
"I think Wang Yan did the right thing. The situation he said will definitely happen. Instead of having conflicts at that time, it's better to talk about the conflicts first, so as to save yourself anger later."
Wang Yan nodded with a smile: "That's what I thought, but what Xia Jie said was correct. It was indeed too direct. But I didn't have the patience to deal with it, so I just said it directly to save trouble. Anyway, I I didn't think about progress, it's good to be a little policeman, I like it."
"Brother, you haven't thought about making progress yet?" Li Dawei widened his small eyes, feeling the unfairness of fate, "Everyone in the institute said that you will definitely be rewarded this time. We have only been here for a few days Huh? It's full of fights and calculations, that is, four days. You caught a fugitive with a reward of [-], you caught two car thieves, you found a drug addict, and you pulled out a thread.
Relying on the image enhancement technology, our office has worked overtime for at least ten consecutive days, and the detection rate has increased a lot.Today, I bumped into the murder scene again, and directly caught the murderer's current situation.Just now, I compared the fingerprints again, and solved a series of burglary cases that had not been solved for three years.Isn't this progress?If I had your luck, and your wealth, I would go sideways. "
"That's Wang Yan's strength, okay? It's a fugitive in front of you, can you recognize it?" Yang Shu is still very impressive, although he also feels hit, but he is not a person who envies and hates, he is A person who wants to do things.
"That's right." Xia Jie helped.
Li Dawei sneered: "I didn't dare to say it before, but since he caught the fugitive, I have been looking at the list of fugitives in our province for the past few days. As long as he appears in front of me, with my piercing eyes, he will definitely let him go." He knows what is called the French Open, and he is meticulous. If he dares to resist, I will set up the Black Dragon Eighteen Hands, hehehehe..."
Xia Jie complained mercilessly: "Forget it, your small eyes are still so sharp?"
……
After playing for a while, the four returned to the building to continue working.
In just one cigarette, Gao Chao had already asked for the fingerprints of several cases in his hand, but Wang Yan did not start the comparison directly, but called the family who had visited earlier and had only children in the family who took the college entrance examination. In the past, I promised to help with the details of the application for the exam at night.
I am not afraid of disturbing others, the place is full of chickens and dogs, and it is not clean at all.Weixin asked, and when he found out it was convenient, he put on his earphones and made a voice call.
Not surprisingly, he opened his mouth to ask about the inside story of Dong Nianfeng's family, but was stopped by Wang Yan's discipline, and then directly chatted with their son this year.
This kid did pretty well in the test, with a score of more than 530 in science, which is enough.Wang Yan chatted with him about his hobbies, what he wanted to learn, and his plans for the future.
It was during this process that Wang Yan was rattling over the list of schools he could get into with this score, majors he could apply for, and so on.I patiently helped the child analyze one by one, and finally selected a few majors in several schools. I don’t know if I listened or not. Anyway, when I hung up the phone after chatting for more than an hour, there was a series of enthusiastic thanks on the other side. , and asked him to go over to eat when he was setting up a school banquet for a while.
And after he hung up the phone, what he got was the surprised looks of the old policemen in the office.
Liu Xianfeng asked: "Wang Yan, will you still guide this?"
"Look at what you said, that person is a college student who just graduated, don't you know?"
Someone said something, and then said, "I've been listening to it for a long time, and what you said is right. If it's convenient, you can show it to my sister's children? Isn't it time to fill out the volunteers these two days? Ask someone to help Look, it costs more than 1 yuan when they open their mouths. They are all from small families. How can they have so much money. But don’t spend it, and I’m afraid that the test will be in vain. My niece did well in the test, and she got nearly [-] points. .”
Wang Yan looked at the time, and nodded with a smile: "Call and ask, see who is awake, and I'll tell her if it's convenient. But let's talk about it first, I'm just a suggestion, listen to it or not, I don’t guarantee what will happen after listening to it.”
"Then don't worry, I can't blame you. I'll call and ask. I guess I haven't slept yet. Their family has been worrying about this for the past two days." This person also knows that Wang Yan's time is precious now, and it's free. For help, he immediately took out his cell phone and made a call.
Even if they don't understand, they understand better than them.And since Wang Yan dared to guide the masses to apply for the exam, with this kid's temperament, he was still very sure, otherwise he wouldn't be too tempted to make trouble for himself.
Soon, Wang Yan made a phone call with the daughter of the old policeman's sister's family. Opposite him was the same family sitting in a row, seriously communicating with Wang Yan.It's still the same routine, basically I didn't trust it at the beginning, but after a few minutes of chatting, it became hot.
After talking about this, no one in the institute looked for him.In fact, there were basically no people in the institute at this time, and many of them couldn't bear to leave.It is not a day or two, but a continuous day at this time, and it is not so pleasant to deal with all kinds of strange police situations endlessly during the day.
Li Dawei and others are still there, but they are almost unable to hold on.If you don’t sleep and play with your mobile phone late, you are energetic. If you do work, few people have such great enthusiasm, especially they still do the writing work of sending people in, which is very boring.The only fun is to ask the prosecutor a lot, this person will have to be sentenced for a few years...
"What time do you plan to leave?" Xia Jie asked.
"Want to go to my place?"
"Well, I can't go home so late. The dormitory is not very comfortable, so let's go to your place first. The two of them are still arguing, and they sleep comfortably on your big bed."
"You are waiting for me in love, so let's go."
"It doesn't matter to us, anyway, there's only so much work, if you do more, you'll finish earlier. Besides, don't you still have a demo file for fingerprint scanning?"
"It's too late to do it tomorrow." Wang Yan smiled, turned off the computer and stood up, crackling in Li Dawei's envious eyes, "Pack up and go back, Jiwei is still scared at home, I guess , shall we have a hot pot and drink some wine to help us sleep?"
"Forget it, I'm so tired. I'll wait another day for drinking. But I agree to eat something. I'm really hungry. And Jiwei must not have eaten. He should not be in the mood to eat." Li Dawei rubbed abdomen.
"Okay, let's drive around and have a quick bite of some fried rice on the side of the road. Xia Jie, do you want some clothes or something?"
Xia Jie shook her head: "Nothing, I'm so busy, how can I pay attention to so much. Didn't you say that you have a lot of toiletries at home? Those are enough."
"Informal, good woman."
Yang Shu agreed: "Indeed, after so many days here, I haven't seen Xia Jie put on makeup."
"I'm a natural beauty." Xia Jie joked, turned her head and left, "Come on, I'm going to be sleepy, I just want to take a bath and sleep well."
A group of people chatted and laughed and left the police station, bought fried rice and fried skewers on the side of the road, and bought some beer to go back.
Sure enough, Zhao Jiwei didn't sleep, let alone eat, his face was pale, lying on the bed with the light on, he really had a psychological shadow.The crowd comforted them, barely ate some food, and drank a few cans of beer. Perhaps because of the popularity in the room, coupled with the effect of alcohol, Zhao Jiwei finally fell asleep.
Li Dawei and others also sighed, dragged their tired bodies, took a bath and went to bed.
Wang Yan helped Xia Jie settle down for a while, then he didn't bother, and went back to his room to sleep. It was another fulfilling day...

(End of this chapter)
Collected fingerprints are divided into three categories, obvious lines, formed lines and latent fingerprints. The former two are visible to the naked eye, while the latter are not visible and require some processing to see the original appearance and extract it.This type of latent fingerprint is the most prevalent in common crime scenes.
There are many ways to collect this kind of fingerprints, such as powder method and magnetic powder method. The former is attached with powder with different colors, and the latter is attached with iron powder, and then the fingerprint can be displayed by swiping with a magnet. The most widely used is the powder method.In addition, if fingerprints are left on the surface of paper, cards, leather, wood and other absorbent items, they must be chemically treated before they can be visualized and extracted.
There are also many chemical methods, such as iodine fumigation, Ninghai Delin, silver nitrate method, fluorescent reagent method and so on.
Materials are needed to do all of these, and there is also a device that can clearly scan and record visible fingerprints into a computer. The combination of the two is fingerprint extraction.The next comparison is to mark the feature points on the fingerprints in the fingerprint library of the public security system, plus the auxiliary screening of the program, and patiently look at them one by one.
In the current situation, there are still very few people whose fingerprints are not in Curry.Fingerprints are required to apply for an ID card, and fingerprints are required to punch in at work. Internet cafes can also use fingerprints instead of ID cards to surf the Internet. In the past two years, facial recognition has begun to be directly connected to the public security system.
As Wang Shouyi said, the things used to extract fingerprints are not expensive, but it is difficult to find all of them for a while.On the other hand, even if you don't have much money, you can definitely spend your own money without spending your own money. The funds in the institute are so tight, let alone tens of thousands, it's [-], which should take advantage of it. have to account for.
Team Luo had already called. Wang Yan and Gao Chao arrived at the place. He had prepared a large box of materials and tools, and he was quite happy.Now someone in the lower-level police station will take fingerprints for comparison, and their work will be much less. After all, it is a jurisdiction with more than 12 people.
But in fact, nothing has changed, it's just that they relax in their hearts.When there was the Balihe police station, they were as busy as dogs, and when there was no Balihe police station, they were also like dogs, it's all the same.It's just that one less person from the police station came to remind me. Although it didn't have a big impact, it was always a little cleaner.
Just like that, driving with a lot of stuff, Wang Yan and Gao Chao found a nice restaurant outside for a bite of food, and then went all the way back to the institute.
"Today, the office has provided desks for you guys. Now, this one is yours."
Gao Chao smiled and helped Wang Yan carry things, and moved to a new desk.He said, "Speaking of which, you earned it yourself. Otherwise, if you want to have a desk and a computer, you will have to wait for two months. It is because your image has been enhanced recently, and the detection rate of our firm has soared, so It is much more convenient for Chang and Bureau Song to ask for funds. Once your fingerprint comparison is done, then we will be able to stand up completely. Image enhancement with one hand and fingerprint comparison with the other, ordinary cases can be solved at least [-]% of the time."
This is opposite to four desks, and another one is opposite to Cao Jianjun's desk, Yang Shu is sitting there, and the remaining four Wang Yan are together.
Wang Yan said with a smile: "It's not that easy. Although there are always shows on TV, people's awareness of protecting the scene is still relatively low. We can only say that we should do our best."
"Just solve as many cases as possible. Just like the thief this time, I guess, he probably didn't wear gloves. Think about it, it's been three years, and he didn't steal [-]. He just wore gloves at the beginning." Yes, after three years, you have been slack, and you are likely to solve the case directly this time."
"Let's take out the fingerprints first and have a look."
"You are too conservative." Gao Chao smiled and pointed at Wang Yan, then waved his hand, "Okay, you can do it yourself, and you can find me if you have anything to do."
After all, Gao Chao greeted people with a smile, and left for the crime scene in Dongning Village...
As soon as the climax left, Wang Yan was surrounded, not only Li Dawei, Yang Shu, Xia Jie, but also old police officers such as Chen Xincheng, and even two prosecutors who were cooperating in the office came over. .
Li Dawei asked: "I heard that there was a murder case in Dongning Village? What happened at the scene? Tell us about it?"
Gossip is human nature, and the police are no exception.In today's society, it is not easy to encounter a murder case, let alone a murder and dismemberment case that is happening in one's own jurisdiction.I want to ask what's going on, and listen to the excitement.
From this direction, the gang of policemen in the Balihe Police Station is no different from the crowd in Dongning village who are blocking the cordon to discuss.
But this also made Dong Nianfeng's impulsiveness even more sad.
Wang Yan looked at Yang Shu: "Can you say it? I remember we are disciplined, right?"
Yang Shu nodded, and said very strictly: "If the case is not closed, we cannot reveal the details of the case, let alone spread it to the people."
"Oh, how can there be so many things? The suspects have been caught. We will know about it sooner or later. It doesn't matter. Look, the big guys are waiting." Li Dawei didn't care, and the others didn't care. not give a damn about.
Of course, Wang Yan didn't care too much. The people who watched the scene had already explained the case clearly, and the whole Ping'an City, which would be able to spread it tomorrow, knew it all.
He laughed and said: "The suspect, the ex-wife cheated on him, caught him in bed, and beat the adulterer half to death... Later, it was found that the child was not his... The scene was quite bloody, the heads of the man and the woman were all used The ax was chopped off, and the woman's arm was also chopped off. The method was relatively rough, and the minced meat was all over the floor, and the blood was sprayed on the ceiling. In addition, there were many open wounds on the two deceased. Suffered a very painful torture..."
"Honest man, who did you provoke?"
"It was the same last year, when I went out to the scene, I cut off one of his hands..."
"I guess it's time for the director to hold a meeting for us. If there is such a police situation in the future, we must pay attention to it."
After hearing the process, especially the bloody crime scene, people said some words of congratulations to Wang Yan, and then dispersed.If there is a murder case, there must be credit.Combined with the soaring detection rate in the past two days, Wang Yan must at least be a commendation.If they had gone earlier, the two victims were still alive, and they were rescued in the end, and the suspect was successfully subdued.
Although they are immoral adulterers and whores, no one takes them seriously, they are 'victims' to the police.
"Have you vomited? I called Jiwei. That kid was sickly and frighteningly pale. When he was talking, he retched just thinking about the scene." Seeing that everyone had dispersed, Li Dawei asked curiously road.
"Do you think I'm throwing up? The big bone in sauce that I ate with Lao Gao just now is very delicious. Let's try it together some other day. The boss's craftsmanship is very good."
"Ugh..." Xia Jie covered her mouth in embarrassment, and hurried out to get some air.
This thing is afraid of thinking, even if Wang Yan's words are dry, the woman with a clever mind can render it into a vivid picture.Pools of blood, minced flesh, and decapitated heads are still scary to think about.
Xia Jie herself has some psychological problems, but she is not afraid of blood, but the feeling of close contact with death, which reminds her of her sacrificed father.She has been resisting, but she still doesn't want to do household registration work, she still wants to make a breakthrough.But her mother didn't give her this chance, and annoyed everyone in the institute, so she reluctantly went to do the household registration work.
This is really impossible, because if everything is treated reasonably, Wang Shouyi, Cheng Suo and others will not allow her to participate in dangerous work, and there is a mother who is a demon at home.
Li Dawei didn't feel very good either, so he took a sip of water tactically to suppress it, and asked curiously: "What's the matter, brother Yan, I heard what Gao Suo said, can you still compare fingerprints?"
"Easy ones can be right, too difficult ones can't." Wang Yan nodded with a smile, opened the box he brought back, and took out various materials from it, as well as the bank card he brought back from the victim's house and several doorknobs. .
"I'm really convinced now. I can enhance images and compare fingerprints. No wonder the director smiles when he sees you. If I were him, I would smile too. Based on these two things, you will be indispensable in the future. Brother Yan, Can you pass it on to me when you have time? I want to learn too."
Wang Yan nodded with a smile, picked up a pen and paper and wrote a bunch of words flamboyantly, tore it off and handed it to Li Dawei: "Come to me after reading all these."
"I don't care. Do you need to read so many books for image enhancement and fingerprint comparison? Eleven books and dozens of papers?"
"This is the basics. After reading these books, general image enhancement and simple fingerprint comparison, as long as you practice in a targeted manner for a month, you can basically handle the most basic ones. There are no tricks in technology, only a lot of related Knowledge reserve and practice can be applied. I just teach you, you don’t understand.”
"Yang Shu, if you are interested, you can learn it." Li Dawei casually photographed the book list on Yang Shu's desk, "Then what, you are busy, Brother Yan, I still have a lot of work in hand Well, finish it early and be quick."
"Look at Brother Chen's eyes." Wang Yan waved his head in Chen Xincheng's direction.
Li Dawei spoke so loudly that everyone in the institute heard their conversation.Chen Xincheng was staring at Li Dawei with a look of helplessness.
"If you don't want to read and study, then you should work quickly and don't disturb everyone's work."
"I also want to improve..."
Even though he was chanting, Li Dawei quietly ran to sit diagonally across from Wang Yan and continued to do paper work.
After sweeping around the busy people in the office, Wang Yan sat there turning on the computer and fiddling with various tools.
Regarding his possible meritorious service, most of the people in the institute congratulated him casually and seemed to be happy. Only Cao Jianjun, who was sitting not far behind him, had a rather unsightly expression.
A young man who has only been here for not even a week, was lucky enough to bump into the murder scene, and he felt a little unbalanced.After all, he also wants to make meritorious service. He is actually more reckless than Li Dawei and Zhao Jiwei.
At this time, Xia Jie, who had been out for a while, also came back. Her desk was next to Wang Yan, opposite to Li Dawei, and next to Li Dawei was Zhao Jiwei.
Seeing Wang Yan fiddling with bottles and cans, Xia Jie asked curiously, "You really know how to compare fingerprints?"
"Look at what you said, can there be any fakes? This bunch of things are all sent by the director and the bureau." Wang Yan's smiling face Xia Jie said, "Are you okay?"
"Well, it's okay. It's just that I feel a little uncomfortable thinking about that scene. It's alright, don't talk about it, I'm thinking about it again." Xia Jie waved her hands again and again, and drank water quickly.
"Is it because of your father's influence that you have trouble in your heart?"
"It's nothing, just work, there are a lot of cases waiting to be settled."
Seeing Xia Jie working seriously, Wang Yan shook his head and continued to work.
First, all the fingerprints on the bank card are swiped out and scanned into the computer.Then, he scanned the fingerprints on the doorknob of the house into the computer together.In fact, this matter is still very difficult, because the fingerprint may be covered, and separating the fingerprint is a very professional and difficult operation.
But Wang Yan will also. He has always learned the key to learning things. It is practical to separate fingerprints, and he will definitely not be left behind.Whether the separated fingerprints can still be used is another matter. In this area, he is only proficient, not proficient.That's why he bought so many things and came back to scan his fingerprints. If there are too many things, the chances are great.
This thing is also a meticulous job, and Wang Yan's movements are not very skilled. After two hours of fiddling, he scanned all the fingerprints of the bank card and a doorknob, and officially started the fingerprint comparison.
Fingerprint comparison involves a lot of professional knowledge. No two people in the world have the same fingerprint. This difference is the same to ordinary people. Only professional people can see the difference. These differences are reflected in the subtle, over the bucket.
There are many fingerprint analysis methods, which have become a set of specific methods as early as the nineteenth century, and all countries in the world have learned and improved them.Wang Yan's meeting is very complicated. Anyway, no matter what the method is, the last thing is to mark the difference in characteristics and compare the fingerprints. If it can be matched, it will be no problem.
After asking for authorization, Wang Yan enhanced the fingerprints, and then pulled them into the fingerprint system to start comparison.
This thing is not difficult for the participants. More than ten characteristic points are marked, and the system automatically screens similar fingerprints according to the characteristics. It is useless for 10 minutes. First, the fingerprints of the stolen elder brother's family of three are excluded. .After excluding the three of them, the rest is difficult.
He successively found the fingerprints of the worker who changed the door, the previous tenant, the bank manager, and the teller. Wang Yan had already collected the information when he chatted with the older brother.The elder brother's house was attacked by thieves, suspicious, and the two original tenants were suspiciously taken away. That's why when he went, he caught up with the new tenant who didn't have a residence permit.
In addition to these, there are even two relatives of the elder brother, who called the elder brother to confirm at night.Eliminate all these, and work hard on the remaining strange fingerprint.
In fact, the workload is not that big, because it has been judged that the suspect who has committed theft more than ten times and nearly twenty times for three years in a row is from Dongning Village.
Migrant workers, even if they have come to work in Pingan City for three consecutive years, it is basically impossible for them to live in Dongning Village for three consecutive years. Their mobility is too great.For villages like Dongning Village, there are several villages in Ping'an City except for the south facing the sea, east, west and north.
So this further narrowed the scope, that is, the household registration personnel of Dongning Village sit in the local household.Then Wang Yan had to do a lot less work of comparing fingerprints. There were only a few thousand people in total, and there was a rough screening system, so there was not much workload.
Wang Shouyi, who did the logistics work for the comrades in the institute, did not come back, and neither did Zhang Zhijie. It is estimated that both of them were affected.The scene was indeed too bloody. When Dui Luo asked Wang Yan about the situation, the busy criminal police inside ran out and vomited several times.
Murder is not uncommon, social conflicts are great, and homicides still happen from time to time.But planned murder and dismemberment are relatively rare.If you don't hit the scene today, and wait until a few days later when other people find the body parts, Bureau Song will be the leader of the task force as soon as the report is received, and the case will be named 'June [-] Extraordinary murder and dismemberment case'.
If it is not broken within a certain period of time, then Team Luo will be transferred from the post of the head of the Criminal Police Brigade of the sub-bureau. Although Bureau Song will not be slapped, it is still a bit dangerous. Detective work...
Again, being a leader means taking responsibility, and luck is really an important factor in being a leader.
Wang Shouyi was old and couldn't bear the stimulation, so it was normal to stay at the scene for a while to help out and go home early to rest.
As for Zhang Zhijie, this old boy not only has to bear the impact of the brutal crime scene, but also has doubts about the community work he has done for 20 years.After all, in the past, Dong Nianfeng chatted with him very well, and he also showed new hope for a new life. He opened a small shop, studied fish every day, and occasionally went out to catch a fish or catch a sea. It was very comfortable.
But there was no sign of it. Today, such a boss came to him as a surprise. If he said kill, he would kill him. It would be strange if he could work hard.I also have to go back to my warm family, heal my wounds, and regroup before setting off.
So when it was almost ten o'clock in the evening, only the climax came back with the four policemen who had passed before.
After saying hello to the people who were still busy in the office, Gao Chao walked behind Wang Yan, leaned on the chair and looked at the magnified fingerprints on the computer, and asked, "How is it? Can you compare?"
"I just found an unknown person, I guess this is left by the thief. It's..."
After Wang Yan finished speaking, he leaned forward and got closer to the screen, comparing the two fingerprints from left to right.
Of course Gao Chao understood what this meant, so he didn't say a word, just looked at the fingerprints on the computer from behind, and quietly watched Wang Yan busy.Although he couldn't understand it, and even though his eyes were a little dazzled, he still insisted on watching.
If there is nothing wrong, this is a thief, he has a sense of participation...
Three to five minutes later, Wang Yan confirmed it carefully, "We have won the competition." While speaking, he clicked the mouse, and the page jumped, and the citizen information was displayed on the computer.
"If there is no accident, it should be this Liu Jialiang, 21 years old. However, it is still not sure whether this Liu Jialiang is, and I have to ask the elder brother again, how is their family's relationship with this Liu family? A lot. Lao Gao, do you want to catch him or not?"
"Needless to say, he is so conservative. His fingerprints are comparable. Isn't he the only one? That's almost the same. But this kid can't run away. The office is so busy, how can I have the time to take care of him and let him sleep well?" Think about it, and catch it tomorrow when you have time. Don’t participate this time, and you have to carry out community work in the future. It’s two different things if you catch it and if you don’t.”
Wang Yan shook his head and smiled: "I can't hide it, it's all the same. I chatted with the elder brother who reported the crime two months ago for more than an hour. If he is arrested tomorrow, the victim must be notified. Believe it or not, this I informed them that the case had been solved, and the elder brother would call me the next moment. The people in Dongning Village knew that I was the one who did the fingerprinting, and they couldn't help but look blankly."
"Hey, as long as you can accept it. When parents protect their children, and you do mass work, then you understand Long Live." Gao Chao patted Wang Yan's shoulder vigorously, "Okay, let's go back early when we're done with work."
"I'm really fine, Lao Gao. The office is so busy now. As a member of the group, I have to help share more work."
"Your boy is more suitable to be an official than me." Gao Chao patted Wang Yan amusedly, "You don't even have law enforcement qualifications, what kind of work can you share?"
"Hey, Gao Suo, that's not right." Liu Xianfeng who was not far away spoke. It was the policeman who brought Wang Yan to the police last night. He was in his 40s and looked sleepy. He was an ordinary middle-aged man.
He said: "This kid is really good at mediating disputes between husband and wife and neighbors. If you don't say that our king has a sharp eye, he knows that this kid is doing a good job with the masses. If this kid is willing to do it, then let him do it." How much work do you think we have done if you have the time to cut off housework for others? I am optimistic about you, work hard."
This old boy is saying good things, laying the groundwork, and preparing to pull Wang Yan into a coolie in the future.
The office is full of veterans, although the people are nice, but they are merciless when they catch young people around.At this point, any unit is the same, that is, bullying newcomers openly.
Wang Yan smiled, ignored him, and said to Gao Chao: "Old Gao, you have to help me, tell the director, let the director use the opportunity to work hard."
"That's for sure, it should be ours. Come on, if you don't want to leave, don't leave, follow the police, and learn more about on-site handling. In addition, I also have a few fingerprints that need to be compared. The case is under pressure, all in the last half a month, I asked the technicians of the branch office to scan the fingerprints, it should not be done yet, I will come over for you to have a look later."
"Okay." Wang Yan nodded in agreement.
It's the same as image enhancement technology, when he compares all the fingerprints in the institute, he doesn't have so much work.And as time passed, for about five or six or seven months, the number of similar cases that occurred in their Balihe district would definitely drop sharply.
Because it is human instinct to seek advantages and avoid disadvantages, there is also a circle for petty theft and petty criminals, and if they are caught hard here, they will naturally stop committing crimes here.The public security environment of the Bali River can be significantly improved.
Moreover, he is still doing community work at the same time, going out to visit during the day, so after five, six or seven months, he can basically visit the jurisdiction area with more than 12 people.With his observation and judgment, at least half of the bad guys in the crowd can be caught.That is another big change for law and order.
"Listen up guys, I guess our director will have to tell you when he comes tomorrow, so I'll talk about it first. I don't care about the cases that require fingerprint comparison in my hands. Let's see Wang Yan's speed. But For current cases in the future, if there is a need for fingerprint comparison, there is no need to go to the sub-bureau, let Wang Yan do it first, and then go to the sub-bureau if it can't be done."
Wang Yan also stood up: "Let me also say that, the comrades in our office should learn to extract fingerprints. Generally, simple fingerprints have no technical content, and most of the cases we face are of this kind. What kind of technology. After you have finished scanning, let me compare them, which is easier.
After a while, I will make a presentation file and send it to our group. Everyone can take a look at it when they have time.It is better to be able to collect in the first time, or to collect in the first time.Ugly speaking, don't try to save yourself trouble, call me every time to go to the scene to get fingerprints, once, twice or three times is no problem, there is a process of learning, but it is unreasonable to call me every time.I am a young man, so I should do more work and learn to improve, but I also know good and bad, and I have a little temper.
The technicians at the sub-bureau are the work they should do, and they provide us with technical support.But I am not, everyone must be clear about this.Otherwise, the young people don't know the importance, and I don't care about the collective honor during the meeting, and just curse people, that's not good.I was punished, everyone lost face, and it also affected unity.
So I hope that everyone can consider the feelings of our young people, don't fool around doing dirty work without thinking about it, playing with fools, and giving you big hats, it is unreasonable. "
Image enhancement is very easy to do. For ordinary images, he only needs to crackle for three to five minutes to solve the battle and call it a day.It is more difficult, it is not a matter of his technology, but a matter of computer configuration.More than ten minutes, twenty minutes, it is possible.
But fingerprint extraction is different. There are no technical requirements. It is the powder method to sprinkle powder, and use a small brush to swipe it for a while.Because there are often on-site fingerprint scanning requirements, it is impossible for one fingerprint, but one piece, so how long does he have to do it?
According to the behavior of these veterans, he can be sure that he will never learn fingerprint extraction at all.Compared to working hard on my own, how easy it is to make a phone call and kidnap righteously.
So he didn't give these people the chance to show their old status, and he didn't care about the so-called sophistication of the world.In the case of unequal situations, the so-called sophistication of the world is probably to put on a layer of cloak for being bullied by others, and also to find an excuse for comfort.In comparison, this situation is somewhat different from those who play rogues and take advantage of others, but there is no big difference. They have certain commonalities.
He has been amiable for several days, his ability has also been displayed, and his temper has to shine. Of course, this is based on his own conditions.
Normally speaking, when receiving a call from others, the excuse is that you are busy and don't have time.After going through this once, twice, or three times, everyone will know his rejection.Or hard and soft, to express your dissatisfaction from the side.
But after all, he is not really a young man who has just graduated and started working, nor is he a silly boy whose blood surges after being fooled by a few words.He didn't care what these people thought at all, he went straight up, whatever he liked.
And to be honest, these people were just unhappy for a while, and then they laughed again after a while, and everyone was in harmony.
Li Dawei, Yang Shu, and Xia Jie were all stunned, did they speak so bluntly?Still open the map cannon?How nice are you usually?Oh, by the way, he is rich, self-willed...
Gao Chao also froze for a moment, seeing the momentary embarrassment, he wittily activated his leadership skills: "Look at what you said, these old comrades in our office are just here to bully you young people? But you said This issue really needs to be taken seriously. It is our problem to use the technology, but we can’t just call you alone. Extracting fingerprints is not an easy job, and it is really impossible to do it all by pointing at you.
In this way, the presentation file you mentioned will be produced first, and I will talk to our director tomorrow.It is also good to learn more skills, because it can better solve problems for the people.But there is something wrong with your attitude, I have to criticize you. "
"Accept criticism." Wang Yan stood at attention, and then looked at the policemen and auxiliary policemen present with a smile, and said, "I did say something wrong, and I didn't consider it comprehensively. I apologize to everyone. I'm sorry, brothers. Don't be as acquainted with me."
Although he has always been majestic and upright, it does not prevent him from being disgusting.If you really want to talk about disgusting people, he is also very good.And he still started the group first, and this group of people didn't have a chance to say anything else.
Chen Xincheng is a good person. He resolved the embarrassment at the moment: "It's not a big deal. Although what you said is a little blunt, it's not rough. That's the way things are. Hurry up and make that demonstration, When you come across the scene later, you taught us a few times in the past, and our firm will be able to compare fingerprints by ourselves in the future. The speed of handling cases will be much faster, and the evaluation will be advanced, so our firm will also be ranked first, and everyone will benefit .”
When he said this, the others followed suit, all smiling and waving their hands, saying that it was not a big deal.He also said that it is a good thing for young people to have a temper. They like what they say.
They also remembered at this time, this kid is still a rich man, and the "low-key" scooter with more than 30 yuan is parked in the backyard, and Li Dawei also showed them the photo, the S200 with more than 8 million yuan Just parked in the underground garage to eat ashes, being a policeman is not enough to earn a living.
Either they are naive and really want to serve the people, or they are rushing to climb up, they should not make trouble for themselves.They all knew that Wang Yan didn't mean to talk, and if he dared to scold them in a hurry, they were not used to it, and they were not afraid of punishment, let alone losing their jobs.And the ability is indeed strong, and the luck is also good. If it weren't for their senior qualifications, it might not be certain who will lead whom.
Only Cao Jianjun looked uncomfortable, but he didn't say anything...
As if nothing had happened, Gao Chao left with a yawn. Everyone was busy, but it was still lively. Li Dawei took Wang Yan out to smoke, and Yang Shu and Xia Jie followed.
"Brother Yan, you will be my real brother from now on." Li Dawei clasped his hands together and took out a lighter from his pocket to light a cigarette for Wang Yan.
Xia Jie hesitated and said: "I don't think this is good. You said it so directly, how will everyone get along with each other in the future? Besides, our director pays most attention to collective honor and unity. He will definitely scold you when he comes tomorrow morning."
"I think Wang Yan did the right thing. The situation he said will definitely happen. Instead of having conflicts at that time, it's better to talk about the conflicts first, so as to save yourself anger later."
Wang Yan nodded with a smile: "That's what I thought, but what Xia Jie said was correct. It was indeed too direct. But I didn't have the patience to deal with it, so I just said it directly to save trouble. Anyway, I I didn't think about progress, it's good to be a little policeman, I like it."
"Brother, you haven't thought about making progress yet?" Li Dawei widened his small eyes, feeling the unfairness of fate, "Everyone in the institute said that you will definitely be rewarded this time. We have only been here for a few days Huh? It's full of fights and calculations, that is, four days. You caught a fugitive with a reward of [-], you caught two car thieves, you found a drug addict, and you pulled out a thread.
Relying on the image enhancement technology, our office has worked overtime for at least ten consecutive days, and the detection rate has increased a lot.Today, I bumped into the murder scene again, and directly caught the murderer's current situation.Just now, I compared the fingerprints again, and solved a series of burglary cases that had not been solved for three years.Isn't this progress?If I had your luck, and your wealth, I would go sideways. "
"That's Wang Yan's strength, okay? It's a fugitive in front of you, can you recognize it?" Yang Shu is still very impressive, although he also feels hit, but he is not a person who envies and hates, he is A person who wants to do things.
"That's right." Xia Jie helped.
Li Dawei sneered: "I didn't dare to say it before, but since he caught the fugitive, I have been looking at the list of fugitives in our province for the past few days. As long as he appears in front of me, with my piercing eyes, he will definitely let him go." He knows what is called the French Open, and he is meticulous. If he dares to resist, I will set up the Black Dragon Eighteen Hands, hehehehe..."
Xia Jie complained mercilessly: "Forget it, your small eyes are still so sharp?"
……
After playing for a while, the four returned to the building to continue working.
In just one cigarette, Gao Chao had already asked for the fingerprints of several cases in his hand, but Wang Yan did not start the comparison directly, but called the family who had visited earlier and had only children in the family who took the college entrance examination. In the past, I promised to help with the details of the application for the exam at night.
I am not afraid of disturbing others, the place is full of chickens and dogs, and it is not clean at all.Weixin asked, and when he found out it was convenient, he put on his earphones and made a voice call.
Not surprisingly, he opened his mouth to ask about the inside story of Dong Nianfeng's family, but was stopped by Wang Yan's discipline, and then directly chatted with their son this year.
This kid did pretty well in the test, with a score of more than 530 in science, which is enough.Wang Yan chatted with him about his hobbies, what he wanted to learn, and his plans for the future.
It was during this process that Wang Yan was rattling over the list of schools he could get into with this score, majors he could apply for, and so on.I patiently helped the child analyze one by one, and finally selected a few majors in several schools. I don’t know if I listened or not. Anyway, when I hung up the phone after chatting for more than an hour, there was a series of enthusiastic thanks on the other side. , and asked him to go over to eat when he was setting up a school banquet for a while.
And after he hung up the phone, what he got was the surprised looks of the old policemen in the office.
Liu Xianfeng asked: "Wang Yan, will you still guide this?"
"Look at what you said, that person is a college student who just graduated, don't you know?"
Someone said something, and then said, "I've been listening to it for a long time, and what you said is right. If it's convenient, you can show it to my sister's children? Isn't it time to fill out the volunteers these two days? Ask someone to help Look, it costs more than 1 yuan when they open their mouths. They are all from small families. How can they have so much money. But don’t spend it, and I’m afraid that the test will be in vain. My niece did well in the test, and she got nearly [-] points. .”
Wang Yan looked at the time, and nodded with a smile: "Call and ask, see who is awake, and I'll tell her if it's convenient. But let's talk about it first, I'm just a suggestion, listen to it or not, I don’t guarantee what will happen after listening to it.”
"Then don't worry, I can't blame you. I'll call and ask. I guess I haven't slept yet. Their family has been worrying about this for the past two days." This person also knows that Wang Yan's time is precious now, and it's free. For help, he immediately took out his cell phone and made a call.
Even if they don't understand, they understand better than them.And since Wang Yan dared to guide the masses to apply for the exam, with this kid's temperament, he was still very sure, otherwise he wouldn't be too tempted to make trouble for himself.
Soon, Wang Yan made a phone call with the daughter of the old policeman's sister's family. Opposite him was the same family sitting in a row, seriously communicating with Wang Yan.It's still the same routine, basically I didn't trust it at the beginning, but after a few minutes of chatting, it became hot.
After talking about this, no one in the institute looked for him.In fact, there were basically no people in the institute at this time, and many of them couldn't bear to leave.It is not a day or two, but a continuous day at this time, and it is not so pleasant to deal with all kinds of strange police situations endlessly during the day.
Li Dawei and others are still there, but they are almost unable to hold on.If you don’t sleep and play with your mobile phone late, you are energetic. If you do work, few people have such great enthusiasm, especially they still do the writing work of sending people in, which is very boring.The only fun is to ask the prosecutor a lot, this person will have to be sentenced for a few years...
"What time do you plan to leave?" Xia Jie asked.
"Want to go to my place?"
"Well, I can't go home so late. The dormitory is not very comfortable, so let's go to your place first. The two of them are still arguing, and they sleep comfortably on your big bed."
"You are waiting for me in love, so let's go."
"It doesn't matter to us, anyway, there's only so much work, if you do more, you'll finish earlier. Besides, don't you still have a demo file for fingerprint scanning?"
"It's too late to do it tomorrow." Wang Yan smiled, turned off the computer and stood up, crackling in Li Dawei's envious eyes, "Pack up and go back, Jiwei is still scared at home, I guess , shall we have a hot pot and drink some wine to help us sleep?"
"Forget it, I'm so tired. I'll wait another day for drinking. But I agree to eat something. I'm really hungry. And Jiwei must not have eaten. He should not be in the mood to eat." Li Dawei rubbed abdomen.
"Okay, let's drive around and have a quick bite of some fried rice on the side of the road. Xia Jie, do you want some clothes or something?"
Xia Jie shook her head: "Nothing, I'm so busy, how can I pay attention to so much. Didn't you say that you have a lot of toiletries at home? Those are enough."
"Informal, good woman."
Yang Shu agreed: "Indeed, after so many days here, I haven't seen Xia Jie put on makeup."
"I'm a natural beauty." Xia Jie joked, turned her head and left, "Come on, I'm going to be sleepy, I just want to take a bath and sleep well."
A group of people chatted and laughed and left the police station, bought fried rice and fried skewers on the side of the road, and bought some beer to go back.
Sure enough, Zhao Jiwei didn't sleep, let alone eat, his face was pale, lying on the bed with the light on, he really had a psychological shadow.The crowd comforted them, barely ate some food, and drank a few cans of beer. Perhaps because of the popularity in the room, coupled with the effect of alcohol, Zhao Jiwei finally fell asleep.
Li Dawei and others also sighed, dragged their tired bodies, took a bath and went to bed.
Wang Yan helped Xia Jie settle down for a while, then he didn't bother, and went back to his room to sleep. It was another fulfilling day...
