Chapter 605: Just Gutter Oil

, update the latest chapters as soon as possible!

The information of the members of the two tour groups, one large and one small, was sent over, and Jiang Yuan and the members of the special class screened them one by one.

If we want to discuss the probability, the probability that the two tour groups will choose to kill is very low. They are even less likely to be linked to the deceased's ex-boyfriend, so the choice to kill will be a purely random matter.

However, we have to admit that such a small probability event is really possible.

Jiang Yuan's most dangerous on-site investigation revealed that the murderer was someone who followed tourist groups and committed murder across the country, and had a habit of returning to crime scenes. Jiang Yuan was almost used as a prop to escalate the crime. He is really not looking for money or power, not seeking fame or fortune, but purely for killing, a pure anti-social personality, a so-called serial killer type of character.

Similar reports can actually be seen in the media. For example, a 10-year-old girl met a young child in the elevator. Her first choice was not to help her go home. Instead, she immediately started beating her for no reason until she got up the elevator. On the 25th floor, he threw it down again. There is also a 13-year-old who dismembered his classmates...

Random murders are particularly difficult to detect. If it were an ordinary criminal police team, they might not consider this issue, but the members of Jiang Yuan's special team had to consider it.

There was something like this in the collection I made before, and it cannot be regarded as an urban legend in any case.

There are many screening methods, the main ones are questioning, taking fingerprints and footprints, and collecting alibi evidence.

It is not necessary to draw conclusions from these things now, as long as they can leave effective evidence for future review.

Just like the question of confidence in the arguments for writing a paper, the evidence is also valid. Ordinary alibi, such as sleeping with the wife at night, is less effective because the wife has a strong motive to lie for her husband. If it were to sleep with the mistress at night, its evidence would be slightly stronger. And if you sleep with a timed love temporary experiencer at night, the evidence will be very strong.

As a result, the two tourist groups were stranded in Ningtai County.

The thirty or so people gradually became irritable.

Fortunately, at noon the next day, Jiang Yuan first completed the screening of these tourists from all over the world, and the bureau waived the room fee for another day, and then they were sent away smoothly.

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

Being a criminal police officer is actually a very experiential job. To put it into perspective, the experience gained in the first half of life is half and half with the experience gained from working as a criminal police officer.

Therefore, things like detectives are not cultivated.

Ordinary police officers can become more powerful by taking cases together.

Jiang Yuan is like this now.

Many criminals think they have come up with some great tricks, but in fact most of them have been thought up by their predecessors. Therefore, many times, when police encounter similar situations, they can react immediately.

This is actually similar to answering questions.

Strange, unseen questions will indeed seem difficult and different the first time you see them. The more you see them, the more clear the solutions will be.

Like the case in front of me, the most mysterious mode is probably the random killing mode.

Jiang Yuan ruled out this point and really wasn't too worried about the rest.

afternoon.

Liu Wenkai came back with a happy face as expected:

"The restaurant owner has a problem."

Jiang Yuan and others immediately returned to the table.

The boss killed the waitress, so this explanation is easier to understand.

Things that are easy to understand are usually things that are easier to happen, and police like that.

"The boss has two mobile phones, and the other mobile phone also has WeChat of the deceased. The records have been deleted. After we restored it, we found that the two of them must have slept together in private." Liu Wenkai directly said the most exciting part, adding : "Judging from the time, it has lasted for several years. The woman should want to sever the relationship now."

"This can be seen as a motive." Everyone in the special team's eyes lit up.

"It's very possible. This boss probably took advantage of the girl's young age and the difference in her hometown and status to deceive her. Now, the girl wants to break up with him and talk about a boyfriend, but he doesn't want to. "Liu Wenkai made a very reasonable guess.

"If he didn't want to, there would be no need to kill anyone." Wang Chuanxing retorted.

Liu Wenkai glanced at him and said angrily: "It's not surprising that the drama will be ruined if you don't get it. Besides, this boss has also been in special circumstances recently, so it should be understandable."

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

"The restaurant he has worked so hard to run for so long is going to be transferred, and he will have to go to jail next, which means that Mi Jia is destined to be out of his control. If it weren't for the mentally ill boyfriend, when the boss's case was prosecuted and he was released from jail, Mi Jia would have no idea where to go." Liu Wenkai actually wanted to express this point of view, and he also said it through Wang Chuanxing's questioning.

Wang Chuanxing hissed, as if he felt the pressure from the old criminal police captain.

Jiang Yuan was unmoved and said, "The punishment for a crime is not a reason for him to commit another crime. If he doesn't want to live, just let him live. Catch him and interrogate him."

"Huh, interrogate him directly?" Liu Wenkai had his own pace and said, "I want to learn more from the side. We don't have anything in our hands now. I'm afraid I can't interrogate him."

"There's nothing else to find at the scene. From the side... the boss was going to jail anyway, so he must have been dealing with things around him. The probability of him showing his weakness is not high. Let's interrogate him directly. The victim was still a minor when he came into contact with him, and they were from the same hometown. This is enough. Judging from the footprints and other factors at the crime scene, it is very likely that he committed the crime. Jiang Yuan made a decision.

In Jiang Yuan's view, Liu Wenkai's cautiousness in this case is completely different from his own cautiousness.

From Jiang Yuan's point of view, the main reason is that there is no evidence directly pointing to the boss. There is a lot of evidence, but the crime scene is the man's own restaurant, so it is reasonable to have DNA, footprints, and fingerprints.

The victim also had an affair with the boss, so even if there is physical evidence, it is the same. It makes sense.

Liu Wenkai is not worried about these. He has handled more cases, and the evidence index is not up to this level, but he is more afraid that the boss is prepared, so he wants to collect some evidence from people around him, which will help to make a breakthrough and use it for interrogation.

It doesn't matter whether it is right or wrong, but Liu Wenkai's style of doing things is different from Jiang Yuan's. On the other hand, the resources that Liu Wenkai can get, including the previous experience in handling cases, are also different from Jiang Yuan's.

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

Liu Wenkai hesitated for a moment, but still did it.

Take people to the boss's home, and then bring the boss back, the whole process is no more than 3 hours.

Then put Meng Chengbiao in the interrogation room, and the two of them confronted each other as if they were facing a formidable enemy.

Meng Chengbiao didn't have much in his hand, almost nothing, this is what he is most nervous about.

As for the restaurant owner - mainly because he is afraid of death.

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

Meng Chengbiao's eyes became more and more determined and cold.

The restaurant owner suddenly smiled bitterly: "What else do you want to charge me with? Just say it, I am willing to go to jail."

His tone was full of courage and timidity, both desire and despair.

Seeing this, Meng Chengbiao did not follow the script and gave a sentence: "The charge is murder, we will ask for the death penalty. ”

The restaurant owner was stunned: “It’s just gutter oil…”
