Team Yan soon returned to an office with the "subway corpse disposal task force" on the door. A female policeman just received a glass of water from the water dispenser. When she turned to see him, she immediately smiled and said, "team Yan, are you back? What's the matter? I have to ask you for help? You've only been in our task force for one day. Why do you have to do something else? "

"Team Ren, count all the social relations between Zhang Chao and Jiangyang, and transfer all the personnel files involved to me." Yan team said in a quick tone, "I want it now. Take me as much as you have. I'll see and you'll find it."

Ren team was stunned with the cup for a while before reacting, and hurriedly said, "OK!"

"Also, go to the economic investigation section on the third floor and ask the Hou bureau from Shanghai stock market for all the information of a man named He Xie." Team Yan gave orders while walking.

"What evil? Who is this? Does it have anything to do with our case? " Ren asked hurriedly.

But at this time, Yan team had hurried into the small office and closed the door.

A fat policeman came to the Ren team and complained, "what's wrong with this? All social relations, I'm afraid there are no less than thousands of people? Such a heavy workload... Ren team, are we sure we want to waste our time on such unimportant things? "

"Tut!" Ren team stared at him, "what nonsense? How do you know it doesn't matter? At least some people are busy. They also have an investigation direction. There are many jobs. Pony, you go upstairs and ask for the information about what evil he is. Everyone else moves! Come on, come on! "

The fat policeman sighed: "what evil is this, and who is it?"

The task force got busy.

Soon, an endless stream of information was sent to the small office where Yan team was located.

Yan Dui put three pieces of paper on his desk, which were densely filled with names, and connected them all by means of mind mapping.

No matter how unsociable a person is, there are hundreds of people who have had some contact from small to large.

And then select some people close to him, and then spread their social network, then the number will increase several times.

This is indeed a great workload. The police can hardly use this way of widely spreading the net. Now the science and technology is so developed. Relying on various technical means and advanced science and technology, the suspects are often reduced to a certain range at the beginning of solving the case.

Yan Dui looked at the paper full of names, holding a elastic ball in his hand and fell into meditation.

The subway corpse throwing case that shocked the whole country under his supervision took place three months ago.

The murder suspect is Zhang Chao he mentioned earlier. The victim's name is Jiangyang.

One afternoon three months ago, Zhang Chao came to the subway station with a suitcase. When passing the security check, the staff found something unusual and stopped Zhang Chao.

Zhang Chao failed to escape. Finally, he lied about a bomb and confronted the police.

At that time, the matter was very noisy. The passengers and staff in the subway station and the residents around the subway station, involving more than 30000 people, were evacuated urgently. Hundreds of police, armed police and firefighters rushed to the scene and surrounded the subway station.

Chengdu's major news media also rushed to the scene for first-hand consultation.

As a result, the police successfully subdued Zhang Chao and found that there was no bomb at all, just a false alarm.

But although there was no bomb in the box, there was a body. The name of the body was Jiangyang.

After Zhang Chao was arrested, the police immediately launched an investigation. Zhang Chao admitted the murder, and all the clues found by the police from the crime scene and some dandruff organizations extracted from Jiangyang showed that Zhang Chao was the murderer of Jiangyang.

And the police visited, also confirmed that the two have been contradictory, Zhang Chao has a motive to kill.

With conclusive evidence, the police filed a public prosecution against the prosecution, and the case was heard in Chengdu court three days ago.

But unexpectedly, Zhang Chao retracted his confession in court and took out the perfect alibi.

This incident immediately caused an uproar and became the hottest news. The police handling procedures and legitimacy were questioned, making the police very passive.

The police immediately set up a task force to mobilize elites to re-examine the case.

The original name of team Yan was Yan Liang. He had solved the snowman serial homicide that shocked the whole country in the northeast. He was recognized as a detective by the police system. In recent years, he was transferred to Chengdu City Bureau, so his superiors immediately asked him to lead the task force in the hope of making a breakthrough as soon as possible.

The reason why Yan Liang participated in the case of He Xie and Li Chenggong is that before he was transferred to the task force, he was entrusted by the Hou bureau to monitor and track Li Chenggong. Li Chenggong was arrested and his entrustment to assist in handling the case was automatically terminated. He just went to hand over the case information. As a result, he learned about what happened in Li Chenggong's villa and the game between He Xie and Hou Bureau, so he became interested.

The Hou Bureau knew Yan Liang's name. He just finished the first level of the game, so he invited Yan Liang to meet He Xie. He wanted to use the insight of the case solving expert to see if he Xie could be found.

Unexpectedly, he Xie played on the spot in the interrogation room, which almost scared Yan Liang and Hou Ju to pee.

Seeing this kind of subversion of the three outlooks, even an ordinary person can't help but find out, not to mention Yan Liang?

So there was a scene in which Yan Liang took the initiative to participate. What he didn't expect was that he Xie actually said that he was related to the subway corpse throwing case.

Now there are three large pieces of paper on his desk, all of which are scrawled.

On these three pieces of paper, the social relations between Jiang Yang, Zhang Chao and he Xie are recorded respectively.

Yan Liang wanted to find duplicate names or similar connections.

But so far, there are only 15 minutes left before the end of the game agreed with He Xie, and he still didn't find anything.

Ren team brought a cup of strong tea and gently put it aside. He also stood by and looked at the information on the three pieces of paper.

After watching for a long time, she couldn't help asking, "this He Xie has no intersection with this case, with the murderer and the victim, even all their relatives and friends. Team Yan, I don't understand... "

"I don't understand." Yan Liang frowned, "but I don't think he will deliberately tease me. First, he's not such a boring person, and second, it's not necessary. So there must be some connection, but I haven't thought of it yet. "

Who won't tease you?

Ren Dui finally swallowed the question. She looked at it for a while and asked, "Yan Dui, this He Xie also graduated from Shuzhong College of political science and law. Isn't this the connection?"
