Chapter 578

The information of the members of the two tourist groups, one large and one small, was sent over, and Jiang Yuan and the members of the cold case task force screened them one by one.

If you want to discuss probability, the probability that people in the two tourist groups would choose to kill is very low. It is even more impossible for them to collude with the deceased's ex-boyfriend, so choosing to kill would be a purely random matter.

However, it must be admitted that such a small probability event is really possible to happen.

In the most dangerous crime scene investigation Jiang Yuan has ever done, the murderer of that case followed a tourist group, killed people nationwide, and had a hobby of returning to the crime scene. He almost used Jiang Yuan as a prop for criminal escalation. It was truly not for money or power, not for fame or profit, but purely for killing, a purely antisocial personality, a so-called serial killer type of person.

Similar reports can actually be seen in the media, such as a 10-year-old girl who met a young child in an elevator. Her first choice was not to help her go home, but to start beating her for no reason, until the elevator went up to the 25th floor, and then threw her down. There was also a 13-year-old who dismembered a classmate...

Random homicide cases are particularly difficult to solve. If it were an ordinary criminal police team, they might not even consider this problem, but the members of Jiang Yuan's cold case task force had to consider it.

There were such cases in the cold cases done before, and no matter what, they could not be seen as urban legends.

There are many ways to screen, mainly questioning, taking fingerprints and footprints, plus the collection of alibis.

These things don't necessarily have to reach a conclusion now, it is enough to leave effective evidence for later backtracking.

Just like the arguments in a thesis have the problem of confidence, evidence also has validity. Ordinary alibis, such as sleeping with his wife at night, have relatively poor evidentiary value because the wife has a strong motive to lie for her husband. If it is changed to sleeping with a mistress at night, its evidentiary value is slightly stronger. If it is changed to sleeping with a temporary love experience master at night, its evidentiary value is very strong.

The two tourist groups were therefore detained in Ningtai County.

The thirty or so people gradually became irritable.

Fortunately, at noon the next day, Jiang Yuan first completed the screening for these tourists from all over the country, and the bureau waived the room fee for one day, which was considered to have successfully sent people away.

"The probability of random killing is relatively low." Jiang Yuan made his own judgment.

Criminal police work is actually a very empirical job. If you want to talk about it, the experience in the first half of life and the experience gained in criminal police work are half and half.

Therefore, things like detective gods are not cultivated.

Ordinary police officers can become more powerful through one case after another.

Jiang Yuan is like this now.

Many criminals think they have come up with some peerless good move, but most of them have been thought of by predecessors. Therefore, many times, when the police encounter similar situations, they can react immediately.

This is actually similar to brushing questions.

Strange, unseen questions will indeed feel difficult and different when seen for the first time, but after seeing more, the solution will be relatively clearer.

Like the case in front of us, the most mysterious mode should be the random killing mode.

Jiang Yuan ruled this out, and he really didn't worry about the rest.

Afternoon.

Liu Liu Wenkai really came back with a happy face:

"The restaurant owner has a problem."

Jiang Yuan and others immediately returned to the table.

The owner killed the female server, this explanation is easier for people to understand.

Things that are easy to understand are usually things that are more likely to happen, and the police like this kind of thing.

"The owner has two mobile phones. The other mobile phone also has the deceased's WeChat. The records were deleted. After we restored it, we saw that the two should have slept together in private." Liu Liu Wenkai directly said the most explosive part, and said: "From the time point of view, it has lasted for several years, and the woman should want to break off the relationship now."

"This can be seen as a motive." The eyes of the people in the task force lit up.

"Very likely. This owner should have taken advantage of the girl's young age and the difference in hometown and status to deceive her. Now, the girl wants to break up with him and date a boyfriend properly, but he is unwilling." Liu Liu Wenkai made a quite reasonable speculation.

"If he is unwilling, there is no need to kill, right?" Wang Wang Chuanxing argued on the side.

Liu Liu Wenkai glanced at him and said nicely: "It's not strange to have a script of destroying what you can't get. And, this owner also has special circumstances recently, which should be understandable."

"What special circumstances?" Wang Wang Chuanxing didn't react for a while.

"The restaurant he has worked so hard to operate for so long is about to be transferred, and he will have to go to jail next. It is equivalent to saying that Mi Jia was destined to get out of his control. If it weren't for the mentally ill boyfriend's move, by the time this owner's case was sued and he came out of jail, Mi Jia wouldn't know where she had run to." Liu Liu Wenkai actually wanted to express this point of view, and it was also said through Wang Wang Chuanxing's inquiry.

Wang Wang Chuanxing hissed, as if feeling the pressure given by the old criminal police captain.

Jiang Yuan was unmoved and said: "The punishment received for committing a crime is not a reason for him to commit a crime again. If he doesn't want to live, just fulfill him. Bring him back for interrogation."

"Eh, interrogate directly?" Liu Liu Wenkai originally had his own rhythm and said: "I still want to understand from the side. We don't have anything in our hands now. I'm afraid it won't be interrogated."

"Nothing else can be found at the scene, side... This owner is going to jail anyway, and he must be dealing with things around him. The probability of revealing his flaws again is not high. Interrogate directly. When the victim was in contact with him, she was still a minor, and they were from the same hometown. This point is enough. Judging from the footprints and other elements at the crime scene, the possibility of him committing the crime is extremely high." Jiang Yuan made the decision.

In Jiang Yuan's view, the point where Liu Liu Wenkai is cautious is completely different from the point where he is cautious.

From Jiang Yuan's perspective, it is mainly that there is no evidence pointing directly to the owner. There is a lot of evidence, but the crime scene is the owner's own restaurant, and it is reasonable to have DNA, footprints, and fingerprints.

The victim also had an affair with the owner, so even if there is physical evidence, it can be explained.

Liu Liu Wenkai is not worried about these. He has done more cases, and the evidence indicators have not reached this level, but he is more afraid that the owner is prepared, so he wants to collect some evidence from the people around him, which is conducive to making a breakthrough for interrogation.

It doesn't matter who is right or wrong, it's just that Liu Liu Wenkai's style of work is different from Jiang Yuan's. On the other hand, the resources Liu Liu Wenkai can get, including past case-handling experience, are also different from Jiang Yuan's.

Jiang Yuan now also realizes this point and decisively decides to advance the case.

Liu Liu Wenkai hesitated for a moment, but still followed suit.

Taking people to the owner's home and then bringing the owner back, the whole process took no more than 3 hours.

Putting Meng Cheng into the interrogation room, it was a confrontation between the two as if they were facing a great enemy.

Meng Cheng didn't have much in his hands, almost nothing, which is where he was most nervous.

As for the restaurant owner—mainly because he was afraid of death.

The two sat face to face in the interrogation room, as if confronting each other.

Meng Cheng's eyes became more and more firm, and more and more cold.

The restaurant owner suddenly smiled miserably: "Whatever crime you want to charge me with, just say it. I'm willing to go to jail."

His tone was full of courage and fear, both longing and despair.

Seeing this, Meng Cheng didn't follow the script and just said: "The charge is murder, we will seek the death penalty."

The restaurant owner was stunned: "It's just gutter oil..."
