Chapter 541 Revenge Against Society

Opposite Chen Yan, Wu Degui stared blankly at the black leather notebook in front of him.

Faced with Wang Fenglei's question, he didn't say anything for a long time, but suddenly he laughed.

"Hahaha!"

"Hahaha! You ask me why I killed them?"

"Money can lead to death, haven't you already known that? I took away all the money in those people's pockets, hahaha."

Wu Degui, who was originally extremely frightened, suddenly changed his expression and became hysterical.

The madness in his eyes was like a crazy wild dog, staring at Chen Yan and Wang Fenglei unscrupulously.

"You were the head of the case back then?"

Wu Degui looked at Wang Fenglei: "I have actually met you."

Um?

Wang Fenglei's expression was startled: "Have you seen me?"

"Yes, I have seen you. After I killed Zhang Huaiying 15 years ago, I later returned to the scene."

"Just mixed in with the crowd watching the excitement, I clearly remember the faces of all you investigators that day."

"But he..." Wu Degui looked at Chen Yan: "Is this your new detective? I have never seen him. Otherwise, it would be impossible for him to trick me out so easily."

While Wu Degui was speaking, Chen Yan kept observing the changes in his expression.

From being calm and uncaring at the beginning, to being nervous and frightened when he saw the black notebook, he was hysterical just now and now he is calm again.

Chen Yan has been trying to figure out Wu Degui's psychological changes.

Wang Fenglei did not answer Wu Degui's words, but frowned and looked at Wu Degui: "You said...every time there is a crime scene, you are there to watch us handle the case?"

Wu Degui didn't seem to care that Wang Fenglei didn't answer him: "Can you give me a cigarette?"

Wu Degui thought of himself: "Fifteen years ago, after I killed Zhang Huaiying, I quit smoking."

"I'm afraid I couldn't help but smoke at the scene where I killed them, leaving behind cigarette butts, ashes or other clues."

"Now I want to have a cigarette, is that okay?"

Wang Fenglei thought for a while, looked at the recorder on the side, and nodded.

The recorder is a young man who doesn't usually smoke, but during interrogations, he always has a pack of cigarettes in his pocket.

Many criminal suspects like to smoke when confessing.

Whether they are smokers or non-smokers, maybe this can relieve their stress.

Wu Degui took the cigarette handed over by the recorder and put it under his nose and smelled it carefully.

He took a deep breath, feeling the smell of tobacco rolling in his nose, and the expression on his face was a little nostalgic.

Snapped!

The flame of the lighter danced slightly, as if it would go out at any moment. Wu Degui tilted his head, took a cigarette and lit it.

Cough cough cough!

Because he had not smoked for more than ten years, Wu Degui coughed violently after one sip.

It took a long time to calm down: "I haven't smoked in many years, and I'm not used to it anymore. I remember when I was driving a truck, I smoked at most two packs of cigarettes a day."

Wu Degui, who was minding his own business, took another drag on his cigarette: "I killed Zhang Huaiying because he laid me off."

"Back then, I actually didn't have to be laid off, but once I ruined his good deeds..."

It turned out that not long after Zhang Huaiying and Qin Yu got married, they hooked up with another new female worker in the factory.

"I came back from a business trip driving a truck. I had a bill for him to reimburse, and I ran into him and that woman in his office."

"He threatened me not to tell me and gave me 100 yuan to keep it quiet."

Wu Degui smiled sadly: "At that time, one hundred yuan was no longer a small amount."

"But later others found out about it, but I didn't say anything."

"Zhang Huaiying didn't believe me and deliberately dismissed me when he was laid off."

"After I was laid off, because I injured my left foot, no one wanted me to do anything, so I could only work as a coolie..."

After being laid off, Wu Degui experienced severe beatings from society, and his hatred for Zhang Huaiying became stronger and stronger.

"Do you believe in the cyclical retribution of heaven? Zhang Huaiying laid me off back then, but he himself was laid off later."

"After Qin Yu divorced him, the woman he was looking for took all his money and ran away. Zhang Huaiying later drove a taxi."

"In order to kill him and prevent you from finding me, I planned for a whole year!"

"You have a grudge against Zhang Huaiying and have the motive to kill him, but what about the other drivers?"

"Do you also have a grudge against them?"

In fact, when Zhang Huaiying died, those who handled the case conducted a detailed investigation into Zhang Huaiying's background.

However, there was a gap of three years between Wu Degui's layoff and Zhang Huaiying's murder.

During this period of time, Wu Degui had never caused any trouble for Zhang Huaiying, so the background mission investigation at that time would not have covered Wu Degui at all.

"No grudge, I don't know those people."

"I don't know, why did you kill them?"

"No money to spend."

Wu Degui paused: "After killing Zhang Huaiying, I was very scared at the time, afraid that you would find me, but a year later, you did not find me. Later, I followed the method of killing Zhang Huaiying and killed another taxi driver. They robbed him of the 400 yuan in his pocket."

"In the next two years, I saw that you never caught me, so I killed two more people."

At this moment, Wu Degui has already returned to the way he was when he first came in. He is not nervous, fearful or frightened. Killing people seems to be just a trivial matter to him.

"What about Li Yansong?"

"The fourth time you killed someone was ten years ago. You didn't kill anyone for ten years after that. Why did you kill Li Yansong yesterday?"

"Li Yansong...is the taxi driver I said I killed yesterday, right?"

"Actually, there is no reason. After I killed the fourth person 10 years ago, I felt that it was no longer interesting, and I was a little scared. I was afraid that if I continued to commit crimes, you would eventually find me."

"But 10 years have passed and you haven't found me yet. At the beginning of this year, I had the idea of ​​killing someone again."

"As for the reason, there is no reason. I just felt that I couldn't help it. I started planning it at the beginning of the year."

"Actually, I had already tried twice before killing yesterday's guy...Li Yansong, but the two taxi drivers were more alert."

"When I asked him to drive into the self-built housing area on Fenghuang Street, they kept chatting with the drivers in the group and told them their location. I was afraid of being exposed so I didn't do anything until early yesterday morning..."

Wu Degui confessed to the facts of his murder. The relevant details of the five past murder cases were consistent with the on-site investigation.

He only learned the method of killing from a foreign movie, and the method of eliminating traces in the car was also learned from a TV series.

In particular, wiping the car with alcohol cotton can eliminate fingerprints and other traces left by you, as well as your own odor.

Because in a TV series, Wu Degui once watched a detective use a police dog to track the scent and find the murderer.

That's why I thought of this move.

And he was afraid that he would miss any details. After every crime, he would write down the details of the cleaning traces on paper in advance, and then follow the steps to clean them one by one.

But when he killed Li Yansong, he forgot that he had adjusted the seat, and he had never adjusted the seat position before.

Wu Degui missed this detail.

It was this detail that finally led Chen Yan to follow the clues and find Wu Degui!
