I didn't expect young people to have some opinions on criminal investigation and criminal psychology, and the two chatted about several cases that have caused a sensation in the province in recent years, and young people actually know about them. An old criminal policeman, what does he like to do the most, he likes to drink and say that he has solved the case, bragging~ awe. The two had a great conversation.

Later, for some reason, I talked about the Xu Baping case.

The young man said, "Do you think Xu Baping is powerful?" ”

The old detective subconsciously said, "Amazing." In his concept, he is not a ruthless person who has killed so many people.

But the young man smiled and said, "I don't think that's what he does." In fact, his modus operandi was very simple and rude, and he didn't put much thought into it at all. First, it is too difficult to detect the crime committed by strangers, otherwise since the founding of the People's Republic of China, those notorious killers who have killed dozens of people are just primary school graduates, and some are simply farmers, why did it take several years to catch them? The second is that the criminal investigation methods of the year were still backward, and if you put him today, the surveillance will be filmed immediately, and you can catch him in one day. ”

Although the old criminal policeman was a little uncomfortable, he also had to admit that the young man had a point.

However, the young man's attitude changed very quickly, and he was very curious and patient, asking him about the details of some cases back then. Because the case was solved long ago and the murderer was caught, as long as the specific identity of the victim was not involved, there was nothing that could not be said, and the old criminal police told him 1510.

In the end, the old detective was drunk and confused, and the young man sent him home.

But he had only seen the young man once, and never saw him again.

……

You Mingxu's eyes lit up when he heard this: "Do you remember that old comrade, what does the young man look like?" What is your name? ”

Xu Mengshan replied: "The man didn't say what his name was, and two years later, I only saw that side, and the old comrade said that he only had a general impression." But dead horses are treated as live horse doctors, hehe, I have already invited the old comrades back, and I will invite a portrait expert later. ”

The portrait expert mentioned here is the one who paints portraits.

You Mingxu was very happy to hear it, even if it was only a general outline, he had a direction. And listening to what the old comrade said, that young man is very consistent with the appearance of the murderer in the surveillance, as well as Yin Feng's description of the person's criminal psychology.

The fourth line of Xu Mengshan's investigation is whether there have been recent reports of assault and stalking women. More than a dozen cases were found in one investigation, but some of them have been proven to be mistakes, and some have already caught the criminals. However, there were two cases where single girls also came home from work in the middle of the night, feeling that someone was following them. But the girl was more alert and quickly ran away. You Mingxu asked Xu Mengshan to check the relevant monitoring to see if he could find clues.

The fifth line is to check the forcible entry into the house. There is nothing to be gained from this line.

And the line in You Mingxu's hand, all the employees and customers of the two bathing cities were checked by her, and there was no suspect. Even those who often come to deliver takeaways, maintenance workers, cleaners, ...... I went through it all too. She also felt that it was not a way to check it like this, she still had that feeling, in fact, the law should be hidden under her nose, and she should not run so far, there should be some relevance, which she ignored.

Yin Feng also thought so, and said to her: "Why don't I take you to press a motorcycle, you are familiar with the process, and then find a massage technician to have a good chat, to see what kind of process they have since the first day they joined the company, who people will be contacted, and how they live all day long?" ”

You Mingxu said, "you! Although she knew that the two families were regular bathing cities, and Yin Feng in the past was not only so depraved, but when she heard him mention eating, drinking, and having fun, she was dissatisfied, thinking that now that the person was in her hands, she naturally couldn't help him, and gave him a firm control. Massage? Let the champion learn to press him!

Yin Feng naturally didn't know You Mingxu's thoughts, and when he saw her coldly refused, he didn't care, so he thought about it and told Chen Feng to find out a set of studious massage techniques and send it to himself. He was smart, he took his phone and read it a few times before remembering it, thinking that he would go home at night...... A smile appeared on his face.

However, although You Mingxu didn't plan to go for a massage, there was something in Yin Feng's words that touched her. She felt an inconspicuous clue appear in front of her eyes. It's just that it's still too early to find out if something can be found. So she turned around and asked a colleague from the information technology department to help her check something.

As a result, everyone didn't expect that the first person to provide breakthrough clues was the supernumerary staff and the gardener of Yin Fengjia-Champion.

It was on the night of the second day after Yin Feng assigned the task to the champion, and it was also the second victim who was killed, and on the past five days, the champion sent a bunch of post directories on the Internet and several IP address tracking results to everyone.

He refused to enter the game, so only Yin Feng, You Mingxu and Xu Mengshan watched on the computer.

According to Yin Feng's instructions, the champion sorted out the posts on major forums discussing some famous serial murder cases. In addition, three posts were also collated, which also have relatively high popularity on the Internet, but they made a special trip to discuss the Xu Baping case. Until last month, there were still replies to these three posts. It can be seen that it is human nature to pay attention to violent things.

From these discussions, the champion selected three IPs.

You Mingxu asked, "How was he chosen?" ”

Yin Feng replied: "I asked him to choose those who he thought made sense." ”

You Mingxu was stunned: The champion is a bit abnormal, so it makes sense for him to choose - isn't it just crooked?

The three of them picked up the information and looked at it.

The owner of the first IP has expressed his views on several serial murder cases on the Internet many times, and has also said once or twice about the Xu Baping case. His opinion is: Xu Baping is a very talented killer, although he has a very poor background and has not read any books, but he can do several cases in a row, which shows that he is smart and flexible. And in his words, there was a meaning, and he felt that Xu Baping didn't care about being arrested at all, what he was looking for was relief.

Yin Feng saw this and praised "That's right".

In addition, the owner of this IP uses the same ID in several forums, so he is a well-known person in this discussion circle.

Yin Feng said: "It's not him. ”

The owner of the second IP seems to have studied criminal psychology and criminal investigation, and every time he posts about a case, he almost deduces the case or analyzes the known means of committing the crime. Although his analysis is right and wrong, he is still right in many places. Xu Mengshan shook his head when he looked at it: "The master is in the people."
