Chapter 1158 A major chapter in the history of criminal investigation

"Here are photos of the scene, take a look." Wang Xin took out two small paper bags and placed them in front of Wang Yan. "This is the last body we found when we found body parts in the car for the first time. This is the second body. The two crimes were committed two months apart. This is the photo of Ding Guian. You can see there is a word righteousness on his arm, the same as the one on the second body's arm.

And this person, like Ding Guian, has type B blood. So based on all these factors, we have temporarily determined that this person is Ding Guian. In addition, I have not figured out what this gesture, with the pinky finger raised, means. "

Wang Xin sighed and said, "Logically, this case shouldn't be ours. It's from Harbin, the arm came from Harbin, and the victim is also from Harbin. But they didn't take the case, and we found it, so it fell on us."

Wang Yan flipped through the photos and said with a smile, "Why, aren't you happy about the case? Besides, the information is so complete, and they have done their best. They must be checking it themselves."

"We have plenty of cases to do, but this one is so confusing and random, and we still have no clues. What do you think?"

"This murderer has developed a murder addiction. He kills people deliberately for the thrill of it."

"How do you see it?"

"No matter what this gesture means, it appeared on two bodies in a row, and there was no connection between the two bodies. This is what you just said about random crimes. In this case, there is only one explanation. The file records that the deceased's belongings were missing, which means he was seeking money.

The first corpse was killed by a heavy blow to the back of the head. The murderer's method of dissecting the corpse was also extremely crude, and he changed tools in the process. First he used a knife, then an axe, and finally a saw. The knife and axe marks were messy at first and then neat, indicating that he was unfamiliar with the method at the beginning, panicked, and acted hastily. Later, he gradually became addicted to it and his mentality stabilized.

When he came to the second body, he cut the throat with a knife, which was straightforward. He was going to kill people. Of course, the money on the body of the deceased was also looted. The gesture of the two arms connected the two bodies together. After all, such coincidences are almost non-existent. Therefore, it was determined that the same person committed the crime, and the method of committing the crime was upgrading.

The first time he committed robbery, he killed someone. The second time he committed murder and robbed someone. If nothing unexpected happens, it won’t be long before he commits a third crime.”

Ma Kui nodded: "We also judged it this way, but not as carefully as you said. So what do you think this gesture means?"

“It means normal.”

"What does normal mean?"

"Don't think so complicated."

Wang Yan didn't suspect that Wang Xin was pretending to be stupid. If he thought too much, he wouldn't be able to think of simple things.

He gave a thumbs up and said, "This is awesome. It's the best."

He retracted his thumb and extended his pinky finger, "So what else can you say this means?"

"Fuck him, he's provoking us?" Wang Xin reacted immediately.

Wang Yan nodded with a smile: "That's what I mean. He got a kick out of killing people and his mind became unstable. Since we couldn't catch him, he kept killing and provoking us. Of course, we can't rule out that his mind cleared up during the process and he had other thoughts. He wanted to live a peaceful life, so he put down his butcher knife."

"Fuck, he even became a Buddha." Wang Xin became even angrier. He had a sense of justice. Moreover, being provoked like this and not being able to catch the person did not feel good.

Seeing Wang Yan flipping through the files again, Ma Kui asked, "What's the matter? Do you have any ideas?"

"I looked at the second body, the photos of the crime scene, and Ding Guian's information. My judgment is that the dead one is not Ding Guian, but the one who committed the crime is."

"What?" Ma Kui was stunned for a moment, "Are you sure? How do you see it?"

"From my judgment based on the deceased's photo, he should be around 30 years old, and Ding Guian is 26. The forensic doctor gave a very large range, so Ding Guian's age was included. In addition, their heights and weights were similar, which led to a misjudgment. Here is the information from Ding Guian's previous treatment. At that time, he was 25 years old, 176 cm tall, and weighed 63 kg. The data is similar to this footprint, but he is a little lighter."

Wang Yan showed the photos and the text on the file while speaking, "So I boldly guessed that the murderer was Ding Guian. He was afraid of finding his head, and he happened to meet this person of similar height and weight. He tattooed the same words on his hand and smashed his face, intending to confuse us. Ding Guian faked his death and got away, making us think he was dead."

Ma Kui nodded: "Your statement is valid and consistent."

"It's useless to confront them. If we can't catch the person, all the efforts will be in vain. According to what you said, Ding Guian has escaped now. He has changed his name and committed crimes randomly. Where can we find him?" Wang Xin scratched his head and smoked the cigarette that Wang Yan threw on the table.

Ma Kui let out a long sigh and shook his head helplessly: "We can only wait for him to commit a crime again. The two crimes were both around Harbin, and maybe the next one will be there again. When the time comes, we will go there as soon as possible. See if you can find him by following the footprints."

"That's terrible. He has changed his name. He will definitely commit crimes somewhere else next time. Otherwise, wouldn't that attract our attention? Ding Guian is not afraid of anything else now. He is only afraid that we will stay in Harbin and know that he is Ding Guian."

Of course, Lao Ma also understood this truth, but he just said it in a positive way. He glanced at Wang Xin but did not refute it.

"You've made progress again. You've thought it through very comprehensively." Wang Yan gave Wang Xin an affirmative look. "It's been more than two months since the last crime. I guess Ding Guian is ready to commit another crime within one or two months. So, you contact all the places and tell them about the case and the characteristics of the little finger. Ask them to preserve the scene as much as possible, and we'll go over and take a look when the time comes.

If the scene was well preserved, maybe we could find the person by looking at the footprints. He provoked the police like this. According to common sense, he would definitely not leave immediately after committing the crime. He would feel happy only when he saw us getting anxious and running around like headless flies. "

"It has to be you. Dogs are not as good as you. Why do we need to train police dogs? Oh, speaking of this, it reminds me. That old blind man has such a good nose, is he wasting his talent in the nursing home? Why don't we bring him to the train station? He will definitely be able to smell the drugs. We can give him a salary and he will have a sense of accomplishment. How great is that."

"Get lost." Ma Kui glared and cursed, "Why don't I take you over there?"

"Give me back my cigarettes, don't smoke them." Wang Yan also waved his hand. "Look at you, I'm kidding. Doesn't this show that you and the old blind man are both powerful? What, can't you be more powerful than the police dogs? The treatment of police dogs is so good."

"I think you're just itching for trouble. Get out of the way and call for help."

So everyone got busy, and Wang Yan started flipping through the files to see if there was any case that could be solved.

In fact, if you ignore the pain of the victims and the reasons for the murders, then the process of solving the case is actually very good. Compared with the constant repetition in the Criminal Science Center, Wang Yan prefers to solve the case on the front line...

Two days passed like this, and on an ordinary morning, the bureau leader came in person to hold a meeting for the Criminal Investigation Brigade. He praised Comrade Wang Yan's spirit of continuous learning and application of technology to solve cases, as well as his contribution in solving hundreds of cases. He called on comrades to learn from him, and publicly announced the appointment of Comrade Wang Yan as deputy captain of the Ningyang Railway Public Security Criminal Investigation Brigade, to assist Comrade Hu Guangjun in leading the work of the Criminal Investigation Brigade, fulfill the duties of a people's policeman, and ensure the safety of people's lives and property.

The comrades in the Criminal Investigation Team were not surprised by this. They all knew that Wang Yan was awesome, but they didn't expect that Wang Yan hadn't been transferred away and was still here. As for being their leader, no one had any objection. His achievements made them feel ashamed of themselves, and they couldn't find fault with his behavior, which was good.

Wang Xin was envious, jealous and resentful. He knew everything, but the two grew up together. He had seen Wang Yan become so awesome since he was a child, and the gap between them was getting bigger and bigger. While he was blessing him, he also felt that if you compared goods to others, you would throw them away, and if you compared people to others, you would die. Of course, he was not very comfortable.

After the promotion, Wang Yan had no leadership role. After all, his superiors looked at whether he could fulfill his duties and ensure the detection rate of cases. His subordinates looked at whether he was clear about rewards and punishments. But the embarrassing thing was that he was the second in command, and he was not allowed to give rewards or punishments.

So even though he is the deputy captain, there is no change. He just provides some technical support, and each team solves the case on their own. He still leads Ma Kui and Wang Xin, and they still solve cases. The difference is that now there is a current case, and in the case of little impact, he is the leader of the case and he also bears the responsibility.

Wang Yan didn't want to challenge Lao Hu's power, so it was not worth it. Lao Hu's requirements were not high, and it would be best if he could move up a few steps before retiring. He couldn't solve the case, but he was willing to do a good job in logistics, and he was counting on Wang Yan to make a contribution and promote him.

Wang Yan didn't like doing these things. After all, if he really wanted to be a leader, this level was not challenging at all. Challenging things would also be dangerous. It would be better for him to solve cases and become a technical talent.

At the same time, he also completed his temporary work in the Criminal Technology Department of the Provincial Department. They were very generous and directly arranged a deputy director position for him. After all, a bunch of people here are not as good as him. As mentioned before, he is responsible for technical training and technical support.

Not only that, he also served as a lecturer at the Criminal Police College in Ningyang, a professional criminal investigation college that was expanded from the People's Police Cadre School of the Ministry of Public Security in 1981 and later became the cradle of the police.

However, he is not a full-time lecturer. He teaches four classes a month, one class a week. If he has something to do, he will notify us in advance and then arrange the class time. He teaches criminal investigation techniques, but it is not limited to criminal investigation techniques. After all, he knows a lot. He discussed with the department leaders and decided to teach one class for an afternoon, directly using the case to talk about the case from beginning to end. He teaches one case in one class, and infuses professional technical knowledge into it.

Although these are also required in normal classes, the lecturer will unconsciously talk about cases and talk about interesting cases he knows to liven up the class. But relatively speaking, his lectures are more comprehensive, after all, he specializes in talking about cases from beginning to end.

There are many things involved, from investigation, to various means of solving cases, to interrogation, and closing the case, which is the all-round application of criminal investigation technology.

So he started writing books again, covering professional knowledge in fingerprint comparison, footprint identification, forensic identification, trace identification, criminal psychology, bloodstain analysis, etc.

He actually has some weaknesses, such as document inspection, trace evidence, toxicology inspection, etc. He is not professional in these things because his past experience involves relatively little of them and he has not studied them specifically.

Except for fingerprints, which he learned specifically, the rest are all from experience. He has specialized in the study of the human body and is a doctor and martial artist. He is familiar with the human body, so he is good at forensic identification and knows footprints. He is familiar with murder, knows all the postures of murder, and understands the effects of various tools, so bloodstain analysis is awesome. He is familiar with murderers and gangsters and has an understanding of people, so he is an expert in criminal psychology.

Other trace identifications mainly depend on his keen observation, just like the one who stole the rail parts before, because he was able to distinguish them because of his meticulous observation.

Although the principle of "biting off more than you can chew" does not apply to him, it is certain that he does not learn useless knowledge, which is really unnecessary. But even so, what he has mastered is quite amazing.

After writing these books, he is destined to leave a strong and colorful mark in the history of Chinese criminal investigation. In another twenty years, when his students are all over the world, he will also become a leader in the field of criminal investigation.

In addition to these, his monthly salary from these three positions was directly around 200 yuan. But he didn't really care about the salary, after all, he wasn't short of money...

In this way, his life became stable. In addition to training high-level professional and technical personnel in the Criminal Technology Department in the morning and taking a class at the Police Academy in the afternoon every Friday, Wang Yan worked on cases during the day and wrote books at home at night. Occasionally, he would go on trains on various lines in plain clothes to catch thieves and human traffickers on the trains and deal with some emergencies.

This kind of life lasted for nearly two months. One day when Wang Xin just got to work, he received a phone call.

Then he looked at Wang Yan and Lao Ma and said, "Ding Guian has made some moves. The bastard really ran away. Last night, he killed a woman in a county town below Chunlin. The key point is that it rained heavily there last night, so the footprints must be clear. Is this good news?"

"There are so many people coming and going, who knows what it will be like when we get there." Wang Yan shook his head, "Hurry up and pack up, it's 300 kilometers, we can drive there, it's faster than taking a train."

Without further ado, Lao Ma said a few words to Lao Hu, and Lao Ma called home, and the trio drove directly to Chunlin...

"Brother, you better keep your awesomeness. It depends on you whether we can catch the person or not. If you let this bastard continue to kill, how many people will he have to kill?"

"If it is possible, I hope that once I use my magic power, I can arrest all the murderers and line them up with me to be shot."

“It would be great if I could really do that.”

"You know what's going on? Why are you still talking nonsense? Drive your car."

"Look at you... Oh, why do I feel a little sleepy? I don't have any energy at all. I want to smoke a cigarette..."

I would like to express my daily gratitude to the good brothers who vote monthly, recommend and read quietly for their strong support!
