National Forensic Doctor

Early morning.

Jiang Yuan was holding a cup of green tea and sitting in front of the computer, watching the surveillance video on the screen.

On Jiang Yuan's left were Wang Chuanxing and three technicians from the map reconnaissance team. The four of them were responsible for converting his direct orders into executable orders. They were all so busy that they often turned pale for a simple order from Jiang Yuan. The search took a while to complete.

On Jiang Yuan's right are Yuan Bomin of the anti-drug detachment and two other anti-narcotics policemen. Yuan Bomin is the direct person in charge of the case, and the other two anti-drug policemen have a better understanding of the environment and drug dealers near Wujia Pavilion.

Behind these people were Huang Qiangmin, Dai Mingsheng and other leaders, all with serious expressions on their faces. The frontline police only need to solve the case, but the leaders have to think more.

Wei Shixing was a breath of fresh air in the command room. He was holding a glass of iced Americano and sitting in front of the computer, playing small games and reading novels. There is nothing going on here without him, and no one expects him to do anything, but the Wei Master himself is too interested in investigation, and naturally he is unwilling to give up Jiang Yuan's special investigation this time.

Jiang Yuan didn't look fast. Although there were multiple screens in front of him, he basically only stared at the main screen. The screens next to him were only for auxiliary use, and he was constantly asked to switch between them.

Whether it was Wang Chuanxing or Yuan Bomin, Jiang Yuan's operations were all in the dark. That is to say, the three technicians from the map reconnaissance team knew what Jiang Yuan was doing, but they were too busy running around to raise their heads.

After working like this until about 2 o'clock in the morning, Jiang Yuan felt that the tea had lost its flavor. He waved his hand and said, "Pause and rest for 10 minutes."

Yuan Bomin was smoking one cigarette after another. When he heard Jiang Yuan's order, he suddenly became anxious.

However, seeing the three picture detective technicians slumped on their chairs as if they had received an amnesty, Yuan Bomin could only suppress his eagerness and sit on the ground with his head down.

Huang Qiangmin was already familiar with him. He handed him a bottle of water and said, "Looking for someone without any clues is like looking for a needle in a haystack. Don't get angry in a hurry."

"I know." Yuan Bomin smiled bitterly: "We have not been idle in these three days, but we have not found any new clues - I am just worried that anything can happen in three days. Alas, I shouldn't have done it at that time The one who asked Lao Hong to be an undercover agent jumped in when he saw an opportunity. He was too greedy. "

"I don't even think about this kind of thing————." Huang Qiangmin tried to comfort Yuan Bomin a few more words, and said: "How about you have a chat with Jiang Yuan? Based on my understanding of him, if he hadn't achieved a staged As a result, with certain clues, he will not rest so soon."

Yuan Bomin was originally worried about disturbing Jiang Yuan, but when he heard what Huang Qiangmin said, he immediately couldn't sit still and thought to himself, if there were any clues,

I can also cooperate offline.

Yuan Bomin quickly came to Jiang Yuan and asked: "Captain Jiang, I want to ask about the progress. Is it convenient?"

"Oh, let's stand and chat. We've been sitting here for too long. I just want to make some tea." Jiang Yuan was next to the podium, pouring tea into his cup.

Yuan Bomin said politely: "I'll do it."

"No, just take a rest and refresh your mind." Jiang Yuan said, and then waved Wang Chuanxing over and said, "Print out the tree diagram I just filled out."

"Yes." Wang Chuanxing acted immediately, and within two minutes, he brought out a piece of paper.

Jiang Yuan spread it flat in front of him and said: "Captain Yuan, look, I filled out this tree diagram casually. It's a bit sloppy. Now there are only tree tops and no trunks. Let's take a look at it like this for now - "

Yuan Bomin didn't care to speak. He nodded and read, and saw that there were more than a dozen names or code names on the first page, some familiar and some unfamiliar.

They are either connected to each other by wires, or are independent next to each other. In addition, before each code name, there are numbers 1, 2, 3, and 4.

"What are these?" Yuan Bomin could guess, but didn't dare to guess.

Jiang Yuan poured boiling water and said: "These are the drug dealers who have just been identified. In the bottom row, the ones marked 2 on the left are the small drug dealers with a long sword, the ones marked 1 are poisonous insects. The ones marked 3 are the red face level 1 A drug dealer, 4 is a first-level drug dealer from Brother Li.”

"The drug dealer behind this 4 is called lipocystis muscle?"

"I named him because his weight and muscle content are obviously larger than normal people, and he also looks fatter. He should have used steroids or something like that -"

"Does the mark 4 mean that he is a first-level drug dealer of Brother Li? Or is it Brother Li?" Yuan Bomin was very nervous, but on the outside, he could not tell at all. It was purely the onset of occupational diseases.

Jiang Yuan nodded and said: "I think they are of about the same level, but they are probably not the same person. From the information I just saw, his sales area is different from Brother Li's. His next home is currently There are two for sure, the ones below the tree diagram.”

"How--how did you find this?" Yuan Bomin couldn't believe it. Catching small drug dealers at the level of Changjian, that is, marked level 2, was a daily task for them, but catching level 3 drug dealers like Honglian was a daily task for them. , it is impossible to be sure of it, and it often requires a long period of research and judgment, and a lot of time and energy to catch it.

Brother Li Si, who is at the next level, is naturally more difficult. This time he was a little anxious, and such a big crisis appeared.

For the anti-drug team, by following the clues and trying to figure it out, it's the end of the road. It's almost impossible to try to go up again. Of course, this is for drug gangs of a certain size that are not members of the Caotai team.

Drug dealers have their own way of survival. It is normal for one or two of the little miscellaneous fish below to be caught, but if a level 3 drug dealer is caught, the level 4 or 5 drug dealers in the chain will definitely take some measures of their own. protective measures.

Moreover, unlike the small drug dealers below, the larger the drug dealers, the lower the frequency of transactions, and they have the money to make various preparations. Not only do they have a low probability of explosion, but they also have a strong sense of prevention.

This is incomparable to Level 2 small drug dealers. Level 2 drug dealers are equivalent to the beasts and horses in the drug industry. They are basically in a state of hand-stopping and mouth-stopping. Many people are in a state of drug trafficking and drug addiction. If they don't work for several days, they will not stop. Both the family above and below will urge me, and I will also be short of money.

Therefore, it was difficult for Yuan Bomin to understand how Jiang Yuan identified the person.

Jiang Yuan understood Yuan Bomin very well. He was working tonight with the temporary +1 skill, and his Iv7 skill was for picture detection. It was only normal that Yuan Bomin could not understand it.

Jiang Yuan thought about it and explained: "I actually checked up level by level. It's simple to say, I first found these poisonous insects that you confirmed, and confirmed their parent company by confirming the transaction behavior."

"Even if there are new cameras, they probably won't be trading under the cameras."

"You don't need to see the trading behavior, just look at the state of these people. A poisonous insect staggered out. After passing a certain intersection, he came back a quarter of an hour later and found that he was in high spirits and his eyes were full of expectation. This shows that What?"

Yuan Bomin was stunned: "You're on drugs, at least you bought drugs?"

"Reasonable reasoning, right?" Jiang Yuan subconsciously glanced at Liu Jinghui in front of him, and then said: "The basic principle is this. I will look around this poisonous insect trading place to see if there are other poisonous insects coming to buy medicine, or appearing in other places. Once the transaction has been completed, we can summarize and consider when the seller came and which intersection he needed to pass——"

Jiang Yuan gestured twice as he spoke, and said: "Let's look at vehicle inspections. It's basically the same strategy now, but vehicles have license plates and different shapes, and the number is relatively smaller than people. Just use software to start. People. If so, even if there is a gait recognition system now, the success rate is not high and it is easy to miss people. "

"Isn't this going to be very slow?"

"Am I going to do it slowly tonight?" Jiang Yuan smiled.

"It's not slow anymore, it's not slow anymore." Yuan Bomin shook his head repeatedly and hesitated: "I still don't understand..."

"When you look for a person or a car, you don't just follow the camera all the way. When you see a car going east, you don't have to keep confirming where the car is. It's directly on the way to the east. Just look for the car at the node on the road. In fact, this job

Most of the time, computer software helps. "

As Jiang Yuan spoke, he briefly explained his understanding of gait analysis, and Yuan Bomin's face suddenly became vivid.

"I will organize a team to arrest people!" Yuan Bomin said with a smile: "You just said it directly, we have arrested everyone now."

"I suggest not arresting people yet. Or arrest one or two selectively to confirm the identity of this fat bag muscle." Jiang Yuan called out to Yuan Bomin, and then said: "Most people, don't move for the time being. Remember Just leave it alone.”

Yuan Bomin hesitated and said: "If the fat bag muscle you are talking about is not Brother Li, maybe you also know where Brother Li is?"

Jiang Yuan: "It's difficult to understand horizontally. Wait a little longer. After I confirm the owner of the lipocystic muscle, he might be able to find Brother Li! Xiu"
