@@Leaving the interrogation room, Chen Yan summarized Wu Degui’s psychology.

From a general perspective, Wu Degui is actually an honest person.

Under normal circumstances, there is no fighting, no fighting, no arguing, but all the anger, injustice and depression are buried in my heart.

Normally, these negative emotions will not appear, but once they accumulate to a certain extent and encounter the right opportunity, the darkness hidden in the heart will burst out like a volcanic eruption.

Killing Zhang Huaiying was the trigger for Wu Degui to vent his dark psychology.

This trigger was like opening Pandora's box, and the devil in Wu Degui's heart was completely released.

From a psychological point of view, the three drivers Wu Degui killed later were no longer purely for robbery.

Just like what Wu Degui personally treated him just now, he dared to continue committing crimes because the detectives never caught him.

It was not until Wu Degui killed three more people after killing Zhang Huaiying that he felt afraid.

In fact, it was because the dark emotions in his heart had almost been vented, so he stopped.

But ten years later, Wu Degui took action again, obviously just to kill people.

When Wu Degui killed the three taxi drivers after Zhang Huaiying, he also robbed the money in their pockets, but what about Li Yansong?

Ten years later, Wu Degui no longer even made any attempt to cover up his murders.

This is a typical social revenge killing.

This kind of person is no different from a madman.

Early on the third day after the incident, Wang Fenglei took Chen Yan straight to Qin Chuan's office.

"Brother Chen, it's all thanks to you this time, haha!"

The serial murder case that spanned 15 years was finally solved today, and a big stone in Wang Fenglei's heart finally fell.

This stone is not just pressing on Wang Fenglei's heart.

Instead, it weighed on the hearts of the entire Shen City Detective Team.

15 years!

Wang Fenglei's name for Chen Yan changed.

"Team Wang, it's my responsibility to handle the case. You're welcome."

Chen Yan smiled. If it were the four cases ten years ago, let alone Chen Yan, even if the gods came, there would be no way. After all, no evidence was left behind.

But the murder of Li Yansong just happened, so as long as there is someone at the scene, there are traces to follow.

Solving the case is just a matter of time.

"You can't say that. I have been following this case for 15 years, and if you weren't here this time, it would be difficult for us to catch Wu Degui!"

Wang Fenglei was quite emotional.

He has also seen the scene, not only the scene of Li Yansong's murder, but also the scene of the first four crimes since Wu Degui killed Zhang Huaiying.

However, all the scenes were the same, nothing was found.

In fact, thinking about it now, Wu Degui must have left clues back then, but no one found out what they were.

Just like this time, shoe prints, dirt and other evidence were extracted from the driver's seat mat.

Wu Degui had also driven the victim's taxi before, so it stands to reason that he would have left similar evidence.

But more than ten years later, no one has thought of it.

Taking a step back, even if you thought about it, you might not be able to find Wu Degui.

The same shoe prints, the analysis results given by the technical team are too rough.

Far from as detailed as a statement.

Without Chen Yan's analysis of the suspect's characteristics based on the shoe prints, it would have been impossible to pinpoint Wu Degui.

There is no luck in solving criminal cases.

There are some things that may seem like coincidences, but they actually appear because you have done your job well.

For example, the little accident of discovering Wu Degui's figure in the video.

Although that group of detectives completed their work quickly, they only watched the video at 3:25 in the morning and discovered Wu Degui.

However, without Chen Yan's portrait of Wu Degui, even if he were caught in front of you, you would not be able to tell that he is the murderer.

There is also evidence about Wu Degui's crime, and it was Chen Yan who took the lead in finding the black leather notebook, ether

Probes, hoses, etc.

The room where Wu Degui lived was not only searched by one person, but also by Liu Qingshan, and the detectives from the Shen City Detective Team led by Liu Qingshan also looked at it, but nothing was found.

This guy actually put something under the high platform of the squatty toilet.

Is this a trick that anyone can come up with?

The house is so big, you can take a look around and see everything.

However, Chen Yan was able to find what Wu Degui had hidden.

This is ability.

This is why Chen Yan is young and has only been in the police for two years. He must be the leader of the serious crime team of the Liao Provincial Detective Brigade. Now let's not say he is on an equal footing with him, but from the perspective of solving crimes, Wang Fenglei knows that he is far behind. A few streets away from Chenyan.

When the crime squad was first established last year, Wang Fenglei was present when Chen Yan was investigating the case of a corpse buried in a pond.

To be honest, at that time Wang Fenglei felt that some of Chen Yan's methods and behavior were a little immature.

But less than a year has just passed, and Chen Yan's progress has been too fast.

"Brother Chen, don't be so polite. I am the deputy captain in my position. Privately, I am a few years older than you. Just call me big brother."

Chen Yan nodded without being pretentious.

Men in the northern part of the country all have such a bold spirit.

This is Wang Fenglei's recognition of his performance. It would be bad if he refused.

"Okay, Brother Wang!"

"Haha, that's right. By the way, after meeting the Qin Brigade, there will be a celebration banquet in the canteen of the Shen City Detective Team at noon. My master said that I will definitely invite you!"

"Okay, no problem!"

The two chatted and soon arrived outside Captain Qin Chuan's office.

There were only a few people who dared to speak so loudly in the office building of the Liao Provincial Detective Brigade.

The door was not closed, so Wang Fenglei knocked on the door symbolically: "Qin Brigade, are you busy?"

Qin Chuan, who was correcting documents at his desk, put down his pen: "I heard from afar that you wanted to invite Chen Yan to dinner."

"What, can I join in the fun?"

"Yes, yes, yes, you are the leader, why not? Haha!"

Wang Fenglei was really happy. Wu Degui's case was solved, which made him even happier than his promotion.

Chen Yan followed Wang Fenglei into the office and immediately saluted: "Hello, Captain Qin!"

Qin Chuan returned the greeting: "Hello, Team Leader Chen."

"You've been very busy lately. You haven't been to my place since the mid-year meeting, right?"

"Fenglei, I think we should arrange an office for Team Leader Chen in the provincial brigade?"

What kind of brain does Wang Fenglei have? As soon as Qin Chuan said it, he immediately agreed: "Arrange! Arrange!"

"It should have been arranged a long time ago. I arranged it myself, right next to my office. I will retire in two years, and Brother Chen will take over haha!"

Wang Fenglei knows the relationship between Qin Chuan and Chen Yan better than anyone else.

Why could Qin Chuan directly become his boss from the position of captain of the Liancheng Detective Team?

You know, normally speaking, after Liu Jinsong leaves, as long as there is no one from the Beijing Corps, he should take over.

However, someone has already talked to Wang Fenglei.

Sometimes, you need to have a pattern in your life.

Wang Fenglei actually didn't care. At his age, he no longer cared about promotion or anything like that.

I just felt a little uncomfortable at the time.

You don't care, you don't care, but if something that belongs to you is taken away by others, everyone will feel uncomfortable.

Therefore, over the past year, Wang Fenglei has basically been lying flat, neither supporting nor cooperating with many things.

He rarely even comes to Qin Chuan's office.

Counting on my fingers, this is probably the second time I’ve come here today...

But now, Wang Fenglei figured it out.

The moment the taxi serial murder case was solved, he figured it out.
To be continued...
