"Those are trivial matters, I didn't kill people, not to mention that I found the murderer, and dealt with it impartially, which is completely reasonable, even if I go to sue me, I'm not afraid."

After Sun Jianguo finished speaking, let us all go back to rest and go directly to the bus company early tomorrow morning. On the way back, I grabbed Liu Yefang and asked, "Senior sister, there is a question between Liu Xinyu and Lan Kai when the lie detector sounds an alarm, why don't you suspect them?" ”

Liu Yefang looked at me a little speechlessly: "A drunk person, do you expect him to remember how to go home?" They can't remember clearly, but they have to say that after they finish speaking, they will doubt whether what they said is right, and in the process, there will be relatively large fluctuations in physiology, causing the lie detector to alarm. ”

"The polygraph is just an auxiliary device, don't think of it as a panacea, many vicious people have a very high IQ and control of emotions, and the polygraph is like a toy in front of them. The murderer in the Green River murder case in the United States, which I mentioned earlier, is such a person that he can deceive himself with the lies he makes, let alone a lie detector. ”

I nodded as if I didn't understand, I feel that the road seems to be like that, anyway, I now think that what I don't understand is right, as long as I hear something new, I will feel that I don't know the calendar, it may be related to my own lack of knowledge, and Zhang Bin is here, there must be a dispute.

I didn't say anything all night, and when I arrived at the office the next morning, I found that all the team members were making preparations, and I cleaned up a little, and waited for Sun Jianguo's order.

When it was almost eight o'clock, Sun Jianguo counted the number of people, said "go", dozens of people all got into the car, the siren sounded all the way, and stopped at the door of the bus company in about 20 minutes.

After getting off the bus, Sun Jianguo immediately asked people to block the bus company, and asked briefly: "Xiao Liu, who to arrest?" ”

Liu Yefang said solemnly: "Colleague A, You Pengcheng, he is the behind-the-scenes manipulator of this case!" ”

Sun Jianguo turned around and nodded a few people, and said quickly: "A few of you go in and arrest people here for me, I want to see where this You Pengcheng is sacred." ”

Seeing that people had entered, Sun Jianguo asked again: "Don't you go in to look for evidence?" ”

Liu Yefang stared at the team members who went to arrest people for a long time, and said softly: "No, if I guess correctly, he will send us evidence." ”

"Sent? Are you sure? ”

Not only Sun Jianguo was puzzled, but even I couldn't understand what kind of medicine she was selling in the gourd, when she said that the murderer was her colleague You Pengcheng, Sun Jianguo did not participate in the investigation here, and may not be puzzled, and I have been investigating here, I personally think that the biggest suspect should be colleague C, but I didn't expect it to be colleague A, playing beyond my expectations, reminiscent of the previous investigation, colleague B said that colleague A was jealous of Cheng Sen's advanced every year, and he could only be the second in a thousand years, is it because of this murderous intent?

After thinking about it for more than ten minutes, I saw my colleague You Pengcheng being escorted out of the bus company from a distance, and he looked stubborn and defiant at this time.

Before we could speak, You Pengcheng spoke first, and shouted loudly: "You police arrest people indiscriminately, I want to sue you!" ”

Originally, because of the blockade of the bus company, it caused a relatively big sensation nearby, coupled with You Pengcheng's voice, people surrounded the cordon one after another, and there was never a shortage of onlookers on this land.

Liu Yefang walked up to him and asked curiously, "You Pengcheng?" You've been hiding a lot and you've done things perfectly, but you're still missing a very crucial aspect. ”

You Pengcheng was struggling with a very violent shaking body, and when he heard this, he paused for a moment and subconsciously asked, "What aspect?" ”

Liu Yefang circled around him and said: "It's just too perfect, in this case, I have to admire your wisdom, you are indeed very good, and you are very thoughtful in all aspects, but this happens to be the biggest point you expose, if you show a little bit from time to time, maybe I will skip you." ”

You Pengcheng felt deceived, and shouted again: "No, I didn't kill anyone, you just tricked me, I didn't kill anyone at all." ”

Liu Yefang looked at him unhurriedly: "With your cautious character, the murder weapon at the time of the crime must have been disposed of a long time ago, but there is one thing you have overlooked, that is, the phone card you used to contact Li Chao and Feng Haojie, if I guessed correctly, the previous owner of the phone card should be Zha Taikang." ”

"Although the phone card is not real-named, I think several of Yang Ziqiang's subordinates should know the number of this card, right? By the way, your two comrades, Li Zheng and Gao Han, are now dead, and Gao Han was killed at the instigation of Li Zheng. ”

"Need I say anything else? If I'm not mistaken, on the night of the incident, it wasn't Cheng Sen who was driving, but you, and the real Cheng Sen might have been knocked out of the carriage long ago. Don't tell me about monitoring, the monitoring was actually recorded the day before, and the day before, Cheng Sen's car was not his own, but your car, you changed the car mark, and did something in the car, and the next day, and then change it back, about this, I believe our trace inspectors can find out the complete evidence chain in your car. ”

"The rope you asked Li Chao to pull is connected to the camera through the space on the top panel, and maybe you can still find traces of the line dragging."

After hearing this, You Pengcheng stopped struggling, lowered his head and said nothing. In fact, Liu Yefang said so much, the only piece of evidence that directly pointed to it was the inconsistency of the vehicle, and this time it was the decisive evidence.

Just when Sun Jianguo was about to have someone escort him to the car, You Pengcheng suddenly raised his head and asked, "I still want to know how you found out about the problem with the vehicle?" I don't think I'm doing anything wrong in this regard. ”

"Yes, you did not do anything wrong, but according to my inquiry in the repair workshop, the bus vehicles are responsible for the maintenance of professional masters, and the bus drivers are disdainful of doing that kind of dirty work, and I saw that you were dressed up quickly, and the last time I talked to us, you showed all kinds of characteristics of cleanliness, and I suspected the reason why you repaired the car."

"Coupled with our inspection of the bus that caused the accident, we found no evidence, and the murderer did not have the opportunity to contact the vehicle after the accident, but still did not find evidence, so there is only one possibility, the vehicle used to record the surveillance the night before was not Cheng Sen's car at all, looking at who Cheng Sen has the best relationship with in the company, only you."

You Pengcheng laughed miserably, and muttered: "I thought it was a perfect crime, but I didn't expect to lose to myself in the end." ”

Bringing people back to the bureau, You Pengcheng quickly explained the whole process of the case. I listened to his confession throughout the whole process, and in the end I could only sigh that life is always better than TV dramas.

You Pengcheng began to murder this murder at the end of last year, when he was wearing Cheng Sen's clothes, stealing money from the K72 bus, and intended to be seen, hoping to take this opportunity to stink his reputation, although at the end of the year, he surpassed Cheng Sen, but found that Cheng Sen's reputation was not bad, so he began to plan the whole case, the first step was to instigate Cheng Sen to gamble, and after gambling his salary, he contacted Li Zheng and asked him to lend him money, just like that, Step by step, Cheng Sen fell into the trap set by his best friend in the company.

In this month, You Pengcheng felt that he could close the net, so he began to contact Li Zheng to prepare to start the operation, the two of them took what they needed, Li Zheng wanted to get all the money from Yang Ziqiang, and You Pengcheng wanted to murder Cheng Sen, and when he died, he was charged with a murderer. So they hit it off, Li Zheng first stole Cha Taikang's mobile phone card and gave it to You Pengcheng, You Pengcheng imitated Cha Taikang's voice to call Li Chao, and in order to prevent the change in his voice from being heard, he also deliberately made a call in a noisy environment.

After changing the logo of the bus, You Pengcheng exchanged vehicles with Cheng Sen on the grounds of vehicle maintenance, and borrowed a Rolex watch to wear on his hand in order to perform more like it.

After picking up Li Chao and Feng Haojie at the Changle Hotel, in order to let the two of them vomit in the car, You Pengcheng even deliberately put vomiting in the car. Sure enough, after the two of them vomited, You Pengcheng stopped and went to the rear to clean, and deliberately hid the watch when he returned to the cab, so as to pave the way for the second trap.

Under You Pengcheng's identification, Li Zheng quickly admitted the fact that he had committed a crime, because in the process of planning, Gao Han also knew the point half-knowingly, and wanted to get a piece of the pie. Originally, they had already been discussed, but Li Zheng was afraid that Gao Han would leak the matter, so he instigated the death row prisoner Zhang Hanyang to kill him, and the bargaining chip was to take care of his parents after he went out.

The whole case is almost seamless from the beginning to the end, whether it is planned or implemented, there is no flaw, and even Sun Jianguo, an old criminal policeman with more than ten years of experience, has made the wrong direction of the investigation, thinking that the person the murderer really wants to kill is Yang Ziqiang, and he is not to blame, one is a gangster who has been lending usury all year round, and the other is an honest driver. However, if this is the case, I am afraid that there will be no results in another year.

Zhang Hanyang ended his life of crime after the court trial at the end of the month because of the crime of murdering others, You Pengcheng and Li Zheng were also sentenced to death for premeditated murder, and Li Chao, Feng Haojie and others were sentenced to varying degrees.

A few days after the end of the court trial, the Municipal Public Security Bureau received a request for help, and a vicious serial murder case occurred in Guangzhou. Hearing that the city bureau had solved a murder case, he sent a letter requesting support.
