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 backlog team 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. It is even less likely that they will be associated with the ex-boyfriend of the deceased, 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. The murderer in this case followed a tour group and committed murders across the country. He also had a habit of returning to crime scenes. Jiang Yuan was almost used as a prop to escalate the crime. He really didn't care about money.
For power, not for fame or fortune, just for killing people, pure anti-social personality, so-called serial killer type 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 was also a 13-year-old who dismembered his classmate...
Random murder cases themselves are particularly difficult to detect. If it were an ordinary criminal police team, they might not even consider this issue, but the members of Jiang Yuan's special case team had to consider it.
There is such a thing in the backlog that I have done before, and it cannot be regarded as an urban legend in any case.
There are many methods of screening, 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 retrospection.
Just like the issue of confidence in the arguments for writing a paper, evidence is also effective. Ordinary alibi, such as sleeping with your wife at night, is less effective because the wife has a stronger motive.
The husband lied. If he slept with his mistress at night, the evidence would be slightly stronger. If he slept with a time-based love temporary experiencer at night, the evidence would be very strong.
The two tourist groups were also 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 country, 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 the 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 at hand, the most mysterious mode is probably the random killing mode.
Jiang Yuan ruled out this point and really didn't worry 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, this explanation is easier to understand.
Things that are easy to understand are usually things that are easier to happen, and police officers like them.
"The boss has two mobile phones, and the other mobile phone also has the deceased's WeChat account. 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 explosive part.
: "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 task force'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 for so long is about to be transferred, and he will go to jail next. It means that Mijia is destined to be out of his control. If it hadn't been for the mentally ill boyfriend at this moment, when the boss's case is settled
, he came out of jail, and Mi Jia didn’t even know where he went.” Liu Wenkai actually wanted to express this point of view, and he expressed it through Wang Chuanxing’s inquiry.
Wang Chuanxing hissed, as if he felt the pressure from the old detective captain.
Jiang Yuan was unmoved and said: "The punishment for committing a crime does not give him a reason to commit another crime. If he doesn't want to live anymore, just let him be. Catch him and bring him back for trial."
"Hey, should we directly interrogate it?" Liu Wenkai originally had his own rhythm, and said: "I also want to know more about it from the side. We have nothing in hand right now. I'm afraid we won't be able to do the trial."
"Nothing else can be found at the scene. From the side... This boss is about to go to jail. He must have been dealing with matters around him. The chance of showing his cowardice again is slim. Let's go to trial directly. When the victim came into contact with him
, he is still a minor, and he is still from the same hometown, this is enough. Judging from the footprints at the crime scene and other factors, it is extremely likely that he committed the crime. Jiang Yuan made a decision.
From Jiang Yuan's perspective, Liu Wenkai's caution in this case was completely different from his own.
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 person's own restaurant, and it is natural that there are DNA, footprints, and fingerprints.
The victim was also having an affair with the boss, so even if there was physical evidence, it would still be reasonable.
Liu Wenkai is not worried about this. He has done more cases, and the evidence indicators are not up to this level, but he is more afraid that the boss will be prepared, so he wants to collect some evidence from the people around him, which will help him make a breakthrough.
used for interrogation.
It doesn't matter whether it's right or wrong, it's just that Liu Wenkai's style of doing things is different from Jiang Yuan's. On the other hand, the resources Liu Wenkai has access to, including his previous experience in handling cases, are also different from Jiang Yuan's.
Jiang Yuan now realizes this and decisively decides to move forward with the case.
Liu Wenkai hesitated for a moment, but still did it.
Taking someone to the boss's house and then sneaking the boss back, the whole journey only takes 3 hours.
When Meng Chengbiao was put into the interrogation room, the two of them faced off as if facing a formidable enemy.
Meng Chengbiao didn't have many things in his hands, almost nothing at all. This was what made him most nervous.
As for the restaurant owner - he is mainly afraid of death.
The two sat face to face in the interrogation room, as if facing each other.
Meng Chengbiao's eyes became more and more determined and colder.
The restaurant owner suddenly smiled miserably: "What other charges do you want to accuse me of? Just tell me. I am willing to go to jail."
His tone was full of courage and timidity, both longing and despair.
When Meng Chengbiao saw this, he did not follow the script and said, "The charge is murder, and we will seek the death penalty."
The restaurant owner was stunned immediately: "It's just gutter oil..."
