Chapter 1148 Tree Diagram
early morning.
Jiang Yuan held a cup of green tea, sat in front of the computer, and watched the surveillance video on the screen.
To Jiang Yuan's left were Wang Chuanxing and three technicians from the Image Reconnaissance Brigade. The four of them were responsible for converting his direct orders into executable commands. They were all very busy. Often, a simple order from Jiang Yuan would take one person a while to search to complete.
On Jiang Yuan's right are Yuan Bomin from the Anti-Drug Brigade and two other drug enforcement police officers. Yuan Bomin is the direct person in charge of the case, while the other two drug enforcement police officers are more familiar with the environment near Wujiao Pavilion and the drug dealers.
Behind them were Huang Qiangmin, Dai Mingsheng and other leaders, all with frowns on their faces. Frontline police officers only needed to solve the case, but leaders had to consider more.
Wei Shijian was a breath of fresh air in the command room. He was holding a glass of iced American coffee and sitting in front of his computer, just playing some small games and reading some novels. He had nothing to do here, and no one expected him to do anything, but Wei Shijian was too interested in investigation, so he was naturally unwilling to give up Jiang Yuan's special investigation this time.
Jiang Yuan didn't look very fast. Although there were several screens in front of him, he basically only stared at the main screen. The screens next to it were just for auxiliary use and he was constantly asked to switch between them.
Neither Wang Chuanxing nor Yuan Boming were able to understand Jiang Yuan's operation. Only the three technicians from the Image Reconnaissance Brigade knew what Jiang Yuan was doing, but they were so busy that they had no time to look up.
After working like this until about 2 a.m., Jiang Yuan felt that the tea had lost its flavor, so he waved his hand and said, "Stop, take a 10-minute break."
Yuan Bomin was smoking one cigarette after another. When he heard Jiang Yuan's order, he suddenly became anxious.
However, seeing the three image detection technicians slumped in their chairs as if they had been pardoned, Yuan Bomin could only suppress his anxious mood 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 be anxious."
"I know." Yuan Bomin smiled bitterly. "We have been busy during these three days, but we haven't found any new clues... I am just worried that anything could happen in three days. Sigh, I shouldn't have let Lao Hong go undercover. He jumped at the chance. He was too greedy."
"I don't want to think about this kind of thing..." Huang Qiangmin tried to comfort Yuan Bomin again, saying, "Why don't you talk to Jiang Yuan? From what I know about him, if he hadn't achieved some interim results and had some clues, he wouldn't have rested so soon."
Yuan Bomin was originally worried about disturbing Jiang Yuan, but when he heard Huang Qiangmin say this, he immediately became restless and thought that if there really was some clue, he could also cooperate offline.
Yuan Bomin quickly came to Jiang Yuan and asked, "Captain Jiang, I want to ask about the progress. Is that convenient?"
"Oh, let's talk while standing. We've been sitting for too long. Let me make some tea." Jiang Yuan was next to the command desk, pouring tea leaves into his cup.
Yuan Bomin said politely: "Let me do it."
"No need, just take a break and change your mind." Jiang Yuan said, then waved to Wang Chuanxing and said, "Print out the tree diagram I just filled in."
"Yes." Wang Chuanxing took action immediately and brought over a piece of paper in two minutes.
Jiang Yuan spread it out in front of him and said, "Captain Yuan, look, this tree diagram is something I just filled out casually. It's a bit sloppy. Now there are only treetops but no trunks. Just look at it like this for now..."
Yuan Bomin didn't have time to talk, he just 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 were either connected by wires or independent of each other. In addition, there were numbers 1, 2, 3, 4 in front of each code name.
"What are these?" Yuan Bomin could guess, but he didn't dare to guess.
Jiang Yuan poured boiling water and said, "These are the drug dealers who have just been confirmed. The one on the bottom row, marked 2 on the left, is a small drug dealer at level 1 of Long Sword, and the one marked 3 is a drug addict. The one marked 4 is a red-faced drug dealer at level , and is a fourth brother Li's level drug dealer."
"The drug dealer behind this 4 is called fat-wrapped muscle?"
"I gave him this name because his weight and muscle mass are significantly greater than that of a normal person, and he also looks rather chubby. I think he's been taking steroids or something..."
"The mark 4 means that he is a drug dealer of the same level as Li Si Ge? Or is he just Li Si Ge?" Yuan Boming was very nervous, but you couldn't tell from his appearance. It was purely because of his occupational disease that he started to suffer.
Jiang Yuan nodded and said, "I think they are of similar level, but they are probably not the same person. From the information I just saw, his sales area is different from that of Brother Li Si. Currently, there are two confirmed buyers for him, which are shown below the tree diagram."
"This...how did they find this?" Yuan Bomin couldn't believe it. Catching small drug dealers at the level of Changjian, that is, those marked as level 2, was a daily task for them, but catching level 3 drug dealers like Red Face was impossible to be sure of. It often took a long period of analysis and a lot of time and energy to catch them.
For Brother Li Si, who is at the next level, the difficulty is naturally greater. This time, he was a little anxious and such a big crisis occurred.
For the anti-drug team, using a similar method of following the clues, the top three layers are the limit, and it is almost impossible to go higher. Of course, this is for drug gangs of a certain size that are not grass-roots teams.
Drug dealers all have their own ways of survival. It is normal for one or two small fry to be caught, but if a level 3 drug dealer is caught, the level 4 and 5 drug dealers in the chain will definitely take some self-protection measures.
Moreover, unlike the small drug dealers below, the larger the drug dealer, the lower the frequency of transactions, and the more money he has to make preparations in all aspects. Not only is the probability of explosion low, but the awareness of prevention is also strong.
This is something that small-time Level 2 drug dealers cannot compare to. Level 2 drug dealers are equivalent to cattle and horses in the drug world. They are basically in a state of no income and no work. Many of them rely on selling drugs to support their addiction. If they don't work for a few days, not only will their upstream and downstream dealers urge them to pay, but they themselves will also be short of money.
Therefore, it was difficult for Yuan Boming to understand how Jiang Yuan identified the person.
Jiang Yuan understood Yuan Bomin very well. He was working tonight with a temporary +1 skill, a level 7 skill related to image reconnaissance. It was normal that Yuan Bomin could not understand it.
Jiang Yuan thought about it and explained, "I actually also checked up one level at a time. It's simple to say. I first found these drug addicts that you have confirmed, and then confirmed their upstream dealers by confirming their transactions."
“Even if there are new cameras, they probably won’t trade under them.”
"You don't need to see the transaction behavior, just look at the state of these people. A drug addict staggered out of the house, passed a certain intersection, and came back a quarter of an hour later. He was found to be in high spirits, with eyes full of expectation. What does this mean?"
Yuan Bomin was stunned: "He took drugs, at least he bought drugs?"
"It's a reasonable inference, right?" Jiang Yuan subconsciously glanced at Liu Jinghui in front of him, and then said: "The basic principle is this. I will look at the area around the drug trading site. If there are other drug-related insects coming to buy drugs, or if there are transactions in other places, then we can summarize and consider when the traffickers came and which intersection they need to pass through..."
Jiang Yuan gestured twice and said, "Let's look at vehicle inspection. Now it's basically the same strategy, but vehicles have different license plates and different appearances, and their number is much smaller than that of people, so we can just use the software. For people, even if there is a gait recognition system now, the success rate is not high and it is easy to miss people."
"This... this will be slow, right?"
"Am I slow tonight?" Jiang Yuan smiled.
"It's not slow anymore, it's not slow anymore." Yuan Bomin shook his head repeatedly and said hesitantly: "I still don't quite understand..."
"When searching for people or cars, you don't just follow the cameras all the way. If you see a car going east, you don't have to keep checking where it is. You can just look for it at the node of the road to the east. In fact, most of the time, computer software helps with this work."
As Jiang Yuan briefly explained his understanding of gait analysis, Yuan Boming's face suddenly lit up.
"I organized a team to arrest people!" Yuan Bomin said with a smile: "You just said it directly, and we have caught everyone now."
"I suggest not arresting anyone yet. Or selectively arrest one or two to confirm the identity of this fat-wrapped muscle." Jiang Yuan stopped Yuan Bomin and said, "For the most part, don't move for now. Just remember it."
Yuan Bomin hesitated and said: "If the fat-enclosed muscle you are talking about is not Brother Li Si, maybe you know where Brother Li Si is?"
Jiang Yuan: "It's difficult to understand horizontally. Wait a moment. After I confirm the upstream supplier of the fat-wrapped muscle, he may be able to find Brother Li Si!"
