...
Jiang Yuan's natural way of doing so brought a silence.
The auditorium with two or three hundred people was tacitly falling into silence, which was a kind of cry in itself.
Everyone here has started working. Those who have been working for a long time like Pang Jidong, should retire after working for a few years. Those who have been short have to have two or three years of experience. No matter how young they are, they will not be sent to participate in the training.
In fact, it only takes a little bit of criminal police experience and those who participate in the investigation and handling of several cases will know how outrageous what Jiang Yuan said.
No matter which route you choose, you can solve the case. It sounds like a road leading to Rome. When you really do things, you will know how difficult it is to find a road, how tiring it is to build a road, and how many things you have to encounter if you want to walk a road.
Mountain sculpture.
Those task forces for serious cases operate several investigation routes at the same time because there is no clear direction. Moreover, because these investigation routes are handled over and over again, it is likely that one of them will be completed.
The rest are all written in the middle of the road, saying that this road is blocked.
As for small cases, small cases are not necessarily easier to solve than large cases.
The small cases that police relatively easily solve are mostly caused by the perpetrator themselves. Either the perpetrator is not rigorous, or the perpetrator himself is a "traditional person" and accidentally gets called out, or, or,
The perpetrators committed crimes in succession, resulting in conjunction with cases, provided more information to the investigator.
Finally, many small cases are also weak because the perpetrators have weak resistance. Although it is not like the big beauty card, it can be used to make pleading transactions, whether in the interrogation room or after being sent for inspection, on the other side of the iron fence forest.
People will put pressure through various means.
The suspects who commit serious cases are often more resistant and know that they may die if they confess. For those who commit small cases, especially when they have a confession, they can delay their sentences. When they have a choice to be sentenced to the actual sentence, they will persist.
Not easy anymore.
For example, the case of "Sunshine Supermarket", the little boss who committed the crime can basically stick to everything, but even so, without a certain amount of investment, such a case may not be solved.
As for rape cases, this kind of case is actually considered a relatively large case, and the difficulty is definitely much higher than the theft case in "Sunshine Supermarket".
Relatively speaking, it is naturally more difficult to "all roads lead to Rome".
However, there are two or three hundred people in the audience. Does some people not believe Jiang Yuan? Do some people dare not believe it? Do some people willing to believe it?
But if you want to believe that if you have a little bit of mind, the first words that float in your mind are "praise and kill".
Silence is the best answer.
Jiang Yuan suddenly realized it.
He is cheating and lacks a correct understanding of the difficulty of certain cases. On the other hand, he is too lazy to do things that are down-to-earth. For Jiang Yuan, that is non-essential. His father.
He rents more houses than free-range cattle. He spends pocket money given by his father every month, so he has the capital to do the down-to-earth one.
Therefore, Jiang Yuan turned a blind eye to the silence below.
If you have any opinions, please mention them. If you don’t give them any opinions, Jiang Yuan will not act according to their expressions.
Jiang Yuan sorted out his thoughts a little and said, "I will follow these plans on the notes you handed out to break down the case one by one. Well, police officers who have ideas in the future can continue to hand over the notes."
Jiang Yuan said that he recorded it in his pen and said, "Forensic botany is very labor-intensive to do, but it is actually simple to say. If the two parties have physical contact, it is possible to transmit and exchange spore powder.
One thing to note here is that some spores are difficult to transmit through simple contact, while others are relatively easy. This can be used as the basic idea to distinguish the original spores from the transmitted spores... Jidong, you are responsible for this
a route.”
"Yes." Pang Jidong stood attentively and saluted.
Although he was the captain from another place, he was always respectful to his master Jiang Yuan, just like he just joined the unit more than 20 years ago and became a master.
Jiang Yuan nodded with confidence.
Pang Jidong's forensic botany skills is rather wrong. He actually has no botanical foundation. He belongs to a type that he doesn't know about forensic botany, but his understanding of forensic botany has already been raised.
Technical talents who know how to use forensic botany, know which case can be found, which case can be solved by forensic botany, and know which solution is more efficient, short, and accurate.
"The idea of ​​joining the case... Wei Shi, what do you think?" Jiang Yuan continued to click on his apprentice's name, and he felt envious below him.
The military commander is back online.
This time, the Wei Shiwei was clean and the background wall was specially cleaned up.
On the big screen in the auditorium, Wei Shiwei's face, which was one meter square, had a clear twist.
Wei Shi waited for a while before saying: "If we solve the case through surveillance video, the main difficulties we are facing are three. The first is that it is difficult to determine which of these people in this period is the suspect.
;Second, even if there is a suspect, the face cannot be seen clearly due to the light surveillance at the bar door and other reasons; Third, even if you can see the face relatively clearly, the face recognition cannot find the person."
Jiang Yuan called him, and it must be through surveillance to solve the case. Although Wei Shihua had no experience in criminal investigation, he could only rely on this point and he was able to do so.
Speaking of this, Wei Shi was relatively relaxed and said: "If you join the case, you can solve these three difficulties well. First, the suspicion of recurrence increases, and second, the face cannot be seen clearly.
, The same can also be determined through other physical characteristics; the third is that there are data from multiple cameras to better facial recognition."
"Okay, I'll leave it to you. Well, Shen Yaowei, you can cooperate with Wei Shi." Jiang Yuan ordered the local second generation to Wei Shi Shi Shi, and the two should cooperate better.
Wei Shi was a little panicked: "Do I investigate independently?"
"If you have any questions, please contact me. In addition, first make a version of the image enhancement." Jiang Yuan signaled Wang Chuanxing to close the communication, and then turned around and said, "Bao Liu, this plan may expand the case. Please send a team of people to follow up.
.No need to guard the military and the others, you can connect the case in parallel and take a look.”
"No problem." Liu Wenkai immediately responded: "This person is very skilled in committing rape. It should not be the first time he has done it. However, the case of our local police calling the police is just like this, and we have to meet with colleagues from other places."
Jiang Yuan tilted his mouth: "You watch it."
Liu Wenkai also laughed out loud. Most of the people sitting in an auditorium were traveling from other places, which was much more efficient than calling and sending a letter to travel on business trips.
"Well, let's talk about the third direction, the idea of ​​finding fibers, I'll do this route." Jiang Yuan said, his eyes naturally floating on his laptop.
In the auditorium, it was unforeseen for half a minute.
Huang Qiangmin looked up, coughed twice, and asked, "Jiang Yuan?"
"Oh, I'm finished speaking." Jiang Yuan sat upright.
No mistakes, one song, one post, one content, one reading!
"Would you like to talk about the idea of ​​finding fibers?" Huang Qiangmin asked.
"Uh..." Jiang Yuan hesitated for a moment: "The main thing is that I've done it."
The detectives who were originally whispering to each other suddenly felt that the surroundings were quiet.
Huang Qiangmin coughed a few times: "Why don't you just talk about it?"
"I'm considering what I've said here, it's hard to do investigations in the other two directions." Jiang Yuan's expression was quite serious, as if he had really considered it for others.
Liu Wenkai: "Then let's go?"
"That's fine." Jiang Yuan answered equally readily. This is indeed a solution.
"Okay." Liu Wenkai laughed, feeling a little weird, but he did get up and leave.
Although it is important to solve the case, there is nothing wrong with training here, and the focus is on training.
Shin Yaowei, Pang Jidong and others also left, while the remaining detectives stared wide, feeling like they wanted to see the magician solve puzzles.
Seeing this, Jiang Yuan took out a pen, wrote a few strokes on the notebook, made a simple outline, and said: "In fact, everyone has experience in handling cases through fiber. As for this case, it is a crime.
The value of the evidence on site is relatively low. The most valuable and important evidence is actually the victim's clothing, especially the front of the clothing."
Jiang Yuan asked Wang Chuanxing to re-release the evidence, and found the P31 picture he wanted, and said: "This is the coat worn by the victim. I asked my colleagues in the laboratory to do a careful inspection and found that the inner lining of the coat,
There are multiple fiber tissues on the site. Some of the fiber tissues are from the victim's own clothing, but some fiber sources are unknown. Here we observe that there are three fibers with tearing marks on the edges..."
Jiang Yuan drew circles on the enlarged picture on the spot and said, "Here, here, here, there are similar fibers. After inspection, it was confirmed that the fiber was natural cashmere and was dyed with burgundy red. In this way, combined with the then
With the surveillance video, we can actually confirm that the suspect is this..."
Wang Chuanxing quickly released the picture P219, a middle-aged man wearing a burgundy sweater.
"Can you do facial recognition?" someone asked in a low voice below.
"I can't do it, I can't take a good face, and the angle is not good." Jiang Yuan said, and said again: "But we can find the vehicle he was riding in when he left..."
This time, Wang Chuanxing had no pictures, Jiang Yuan had a sex operation and took out a picture of the vehicle.
"Have you taken a taxi?" Someone saw the operation information above. This time, Jiang Yuan didn't need to say anything else, and immediately said: "If you find the information of the taxi driver through the vehicle, you can basically determine the identity of the suspect!"
"That's it. Let's stop here today." Jiang Yuan began to pack up his things silently.
The criminal police in the auditorium watched Jiang Yuan leave.
The moment the auditorium door closed, it made a "cool" sound, and it became noisy and lively:
"Damn!"
"grass!"
Chapter completed!
