Chapter 544 Say You Can, You Can

Luojin City Criminal Police Detachment.

Several young criminal policemen walked in quickly, greeting all the way, and when they saw Pang Jidong, they also said all the way: "Morning, Pang Da Team."

Pang Jidong seemed to be wandering, with a cup of coffee in his hand, moving slowly. If it wasn't because he moved too slowly, the coffee would have overflowed and burned his hands.

A few people thought that Pang Jidong didn't hear it, so they got closer and said loudly: "Morning, Team Pang."

"Ah...early...morning." Pang Jidong raised his head and replied to several people, his expression still stiff.

Several young criminal policemen climbed up the stairs with a smile. When they reached the third floor, they smiled at the people around them and whispered:
"What happened to Team Pang? Their eyes are all straight."

"It's a bit like the feeling I felt after running five kilometers. I can't think of anything, my head doesn't turn, and I have to wait for energy to come up in a daze."

"It's a bit similar to my state before the entrance exam. Especially when making up lessons, the teacher stares at you teaching. After a class, my head seems to be full."

"You'd better fill your head with..."

meeting room.

After everyone arrived, the detachment leader immediately held a case analysis meeting for the second sexual assault case.

Not counting the prompting factors of the current case, the case named by the task force as 110 is the most urgent case that Luojin City wants to investigate.

Not only is the case itself very bad, but the key is that criminals who have not been punished are very likely to commit crimes again.

There may be various reasons for the current suspension.Maybe the criminal was hit by a car and died, maybe the criminal was hit by a wind immediately, or the criminal was hit by a car on the way to eat barbecue, and he didn't die at the time, but was hit by a car again on the way to the hospital, and died of pain in the ambulance in the car...

But it is also possible that the perpetrator just encountered some things, but did not die.As the matter ends and the surrounding environment changes, he will decide to commit the crime again.

Serial rape is the same as serial murder. The murderer has more or less psychological problems. It is wishful thinking to expect him to stop automatically by relying on his own will or other reasons.Grabbing and dying is the most reasonable solution.

In addition to the members of the Luojin City Criminal Police Detachment, there were also Cui Xiaohu and Li Haochen from the ministry.

Forensic botany is still quite rare. Although ministries and commissions are useful, they are rarely used. Moreover, most of them are still found by botanists outside.Unlike a policeman like Jiang Yuan, who can finish the case directly in one go, which is equivalent to a one-time solution.

The ministries and commissions have high expectations for Jiang Yuan.

If this thing is done well, there will be many accumulated cases that can be solved, and it can go back a very long time.Just like the emergence of DNA technology, it is possible to solve the cases of the Napoleon era.

After a brief narration, Jiang Yuan turned on the microphone and said: "

"The geographical characteristics of this case are relatively obvious. The criminal should be very familiar with the eight scenes and the surrounding areas, at least they have stepped on them before the case. Although it has been a long time, I still hope to check the surveillance."

The detachment leader immediately said: "No problem, let the four brigades take charge, Old Pang."

"That..." Jiang Yuan would not interfere with the leader's deployment of troops before, but this time he was on the mission, so he bite the bullet and said: "Wang Zhi, I just got acquainted with the Pang Da team, can I continue to follow Pang Da's team?" Let's investigate the case."

Wang Zhi couldn't help looking over.

Pang Jidong's face was full of bewilderment, and his eyes were full of clarity.He has been fed too much by Jiang Yuan in the past few days, and it feels like he can't fit it anymore, but if he is familiar with it, he doesn't know if it is considered familiar after his brain burns.

"It's okay. If you like Lao Pang, let him continue to cooperate with you." Wang Zhi followed his example and appointed a newcomer to be in charge of video surveillance.

The Luojin City Bureau does not have a dedicated graphic investigation brigade. The main reason is that conditions do not allow it. There are not so many technicians in the establishment, so for the time being, ordinary police are used to do graphic investigation work by watching the surveillance with eyes.

In this case, unconventional image reconnaissance results are also unlikely.

Jiang Yuan didn't pursue this either, and continued: "If everyone agrees that the criminal lives nearby, I actually have another way to find the criminal."

"Tell me." Wang Zhi looked over in surprise.He received Jiang Yuan's report before, and he looked at it for a long time at his desk, but he didn't think of a plan to catch people, but he didn't expect Jiang Yuan to give something here.

Jiang Yuan pondered for a while, and said: "We determined the eight sites based on the sporopollen on the four victims, mainly the sporopollen in the clothes. But from another perspective, the sporopollen on the victim's clothes In fact, the powder does not only come from the crime scene, but a relatively small part comes from the perpetrator, that is, the criminal..."

Wang Zhiting's eyes lit up, and he immediately asked, "Can we find the criminal's location?"

"You can delineate a general location, but this is more complicated, and there is a certain probability of error." Jiang Yuan turned his head to look at Pang Jidong, and said, "Team Pang, if I told you about the plan to find the criminal, you give Wang Let’s talk about it.”

Simple cramming education also requires questions and assessments, otherwise how to consolidate knowledge and build your own knowledge structure.

Pang Jidong was a little silly, isn't this the stage for you to perform?You ask me, how do I know... Hey, I seem to know a little bit.

Pang Jidong touched his newly grown brain, frowning suspiciously.

"Old Pang?" Wang Zhi urged.

Pang Jidong coughed twice, and said: "According to Team Jiang's previous statement, it seems that some pollen maps outside the pollen map can be found, that is, there are large and small pollen maps, and the difference between them may be brought by the criminal. ...Is that what you mean?"

He turned his head and asked Jiang Yuan.

"It's not completely accurate, but it's okay...just understand and use it." Jiang Yuan didn't expect Pang Jidong to master forensic botany, as long as he knew how to use someone who had mastered forensic botany.

From Jiang Yuan's understanding, as long as Pang Jidong can grasp the boundaries of forensic botany and know which clues forensic botany can produce and which ones can't, it's basically the same.

Of course, Pang Jidong should also know some fundamental things, so as to determine the value of the clue.It is as if there are two clues pointing to two investigation directions at the same time, one clue is brought by DNA, and the other is brought by footprints, so there is no doubt that you must follow the clues of DNA, because DNA clues are safer than footprint clues Too much.

That is, DNA evidence has a higher degree of confidence.

Forensic botany pays more attention to the confidence level. For example, the confidence level of the pollen map is much higher, while the confidence level of a single pollen is much lower. A large amount of pollen is different from sporadic pollen. Wind-pollinated pollen Confidence is lower than insect vectors and lower than algae...

"To be more specific, how do we find the suspect?" Wang Zhi couldn't listen anymore.

Pang Jidong looked at Jiang Yuan in a daze.

"You talk first." Jiang Yuan continued to give the opportunity.

"What do I know...but...if it's in the area, is it possible to find the criminal if you find the place where the pollen pattern of the difference matches?" Pang Jidong tapped his brain, feeling something growing out of it. something that belongs to you.

Wang Zhi looked at Jiang Yuan and asked, "Can it work?"

Jiang Yuan nodded and added: "It's almost the same, but you have to consider the source of the pollen on the criminal, it's definitely not just the home and location. In short, it's impossible to find the only place accurately in this way. You have to check some places .”

"That's enough." Wang Zhi felt a lot more relaxed, looked at Pang Jidong, and said with a smile: "Old Pang is okay, I learned something."

Everyone in the conference room was familiar with Pang Jidong, and they all nodded in approval.

"I've heard a lot from Team Jiang recently." Pang Jidong was a little embarrassed to hear that, and said modestly, "I've learned a little, but I haven't learned enough."

Jiang Yuan opened the system page and took a look. The task was not completed, which meant that he did not learn enough.

Following Pang Jidong's words, Jiang Yuan said: "It's because my teaching time is too short. I happen to be partnering with the Pang Da team in the past few days. I try to spend as much time as possible."

Pang Jidong's smile changed slowly, and gradually became stiff: "That doesn't have to be..."

It's not that he doesn't want to study, but he thinks the cramming method is too cruel, and he doesn't like the feeling of being unconscious at any time.

The people around don't want the encouragement of money, so they don't care so much, and rush out:

"Old Pang is amazing!"

"Old Pang is fine, make full use of the advantages of your partner."

"From now on, Pang Jidong will be No.1 in Botany in Luojin City!"

Pang Jidong quickly waved his hand and corrected him: "I can't talk about this, I'm so old."

"It's okay, since Pang Da is willing to learn, I will definitely teach him well. Let's arrest people." Jiang Yuan patted Pang Jidong on the shoulder, looking very familiar.

Pang Jidong wanted to say that I did not, and wanted to answer no, but he had to arrest people...
