Lu Yun's words are not profound.

Lin Lei's eyes narrowed slightly, and he was silent.

Qiao Yan's eyes widened, and she said incredulously: "Sister Yun, if that's the case, then the person who saw Jiaziyi @shirt @ no@ walking out of the police room is the real murderer-"

Could it be that this is a completely self-written, self-directed and self-acting bureau?

Katsu Kojima and the others, oh no, scum, they can't be called human - they use extremely perverted means, XING tortures Kagawa Yoshiko to death.

Afterwards, they let out the wind and said that Kagawa Yoshiko "clothes @ shirt @ not @ whole" and "crying and crying" left the police office.

This is "self-defilement".

That's right, anyway, there is no evidence, and they have nothing to do.

But since there is such a rumor, everyone will think that Kagawa Yoshiko committed suicide after leaving the police office, so there is also a question - Kagawa Yoshiko was not killed in the duty room!

I don't know how these things were known by the "Inquisitor of Hell", so he began to kill......

Just when Lu Yun and Qiao Yan were still thinking about various possibilities, Lin Lei suddenly spoke: "There are many speculations about the case, and how to lock the real murderer in the end." To put it bluntly, it's just our speculation. I think it's imperative to get back to the heart of the matter, how did those policemen die?"

Lin Lei is right, the interpretation of the case is as wild as you want, but if there is no evidence to lock the real murderer, everything will be in vain.

Lu Yun calmed down her emotions, thought about it again, and said, "Lin Lei, you're right. So let's go back to the very core part of the case – the scene. I don't think there's something that makes sense, and I can't figure it out. ”

Qiao Yan's eyes widened, and she blurted out: "Sister Yun, do you have something you can't figure out?"

Lin Lei smiled slightly, indicating that he understood.

Everyone is a smart person, and there is no need for Lu Yun to explain, there is obviously something extremely unreasonable in this case.

And that's—

XING choked.

That's right, the deceased in a women's swimsuit, suffocated!

Now the police have basically ruled out suicides and accidents - because this is a serial case, two people in a row played XING suffocation and played "to the sky", this possibility is almost none.

The murderer did this, more like a kind of performance art, in order to punish Katsu Kojima, Ichiro Takekoichiro and other dregs in the world......

To put it more simply, the police are so talented, they use the term "judge from hell" to describe the murderer, which is simply three points!

It is clear that the murderer made the scene of XING suffocating after Katsu Kojima and Koichiro Takekoichiro suddenly strangled them by the neck with a rope and strangled them to death.

Here we must explain the "Yoshikawa Line" again.

To make a long story short, the Yoshikawa Line has already been described in detail in the Yamanakaji Secret Room Murder Case, and it is simply understood that it is the traces of struggle when he was strangled to death.

Katsu Kojima and Koichiro Takekoichiro both have Yoshikawa lines around their necks.

However, their situation is not the same as "self-hanging" in the traditional sense.

They didn't hang themselves for the sake of hanging.

In the state of XING's suffocation, their brains are already hallucinating, so even if they scratch their hands indiscriminately, it doesn't necessarily mean that they are killed.

The basis for the police's judgment of his murder was mainly the serial case.

How did the murderer manage to make the deceased completely defenseless?

This question is crucial.

Kojima is burly, Ichiro Chuchu is also strong, and their profession is - police!

What does this mean?

Lin Lei can't answer now.

……

After several hours of detailed investigation, Qiao Yan used all the advanced equipment and chemical reagents in the lockbox she carried with her, and finally had to give up.

Qiao Yan did not find any useful trace evidence.

No solution.

The situation on the scene is two clear words, and there is no solution.

All the places that should be investigated, the police have investigated in detail, and the scene was very "clean" at the time of the crime, and the murderer was meticulous, leaving no obvious and useful traces and physical evidence at all.

This is not surprising, the ability of the criminal police to investigate the scene is not to say, they did not find obvious traces and physical evidence, so it is impossible for Lin Lei and others to find anything.

Looking at Qiao Yan and Lu Yun's somewhat deflated expressions, Lin Lei comforted: "It's okay." There are no traces at the scene, which is actually the biggest trace, indicating that the murderer appeared in front of the deceased with a very peaceful image. At the same time, it also shows that the deceased was completely defenseless against the murderer. Such a peaceful scene is enough to explain a lot of problems. ”

Lu Yun nodded slightly, and said in a low voice: "The deceased didn't have the slightest struggle, let alone any traces of resistance and fighting. ”

Qiao Yan thought for a while and whispered: "My so-called no trace is not an absolute sense of no trace. There is no such thing as a completely clean scene. Because the police office is a place that is open to the public, not a private place. Of course, there will be various traces left by the people of the past in the police room, but this will not help solve the case in any way. ”

After a pause, Qiao Yan continued: "The road of on-site investigation can't be followed, what should I do next?"

Lu Yun subconsciously set his eyes on Lin Lei, but saw Lin Lei shaking his head with a wry smile, which meant that he didn't have a point.

"I'm a little tired today, let's go back and rest, and then discuss the case in the evening to see how we should investigate tomorrow. This time, Lu Yun made the final decision.

Lin Lei and Qiao Yan immediately agreed.

After leaving the scene of the crime, everyone went straight back to the Ota Mansion.

Lu Yun and Qiao Yan got together after returning to the room, and they didn't know what they were talking about, it was estimated that the two of them would touch the case first, and then look for Lin Lei when they turned around.

Lin Lei was a little bored in the room alone, and said to Lu Yun, saying that he was going out for a walk by himself, and by the way, he thought about the case.

In this way, Lin Lei walked out of the Ota Mansion alone.

It was already five o'clock in the afternoon.

The dinner time scheduled by Lin Lei and his party was half past six, and there was still an hour and a half for Lin Lei to "walk around".

Lin Lei silently walked on the streets of Beetsu Town, repeatedly deliberating on the facts of the case in his mind.

Who can make Katsu Kojimaga and Koichiro Takekoichiro completely defenseless?

If it's just to make Kojima Katsu defenseless, then maybe it's still possible, but it's obviously impossible to make Takenitakata completely defenseless!

You must know that Ichiro Takekoichiro was on duty late at night, and Kojima Katsu had been killed in the duty room before, no matter what, it was impossible for Ichiro Takekoichiro not to be prepared for someone coming on a rainy night!

Thinking of the words "people coming on a rainy night", Lin Lei couldn't help but suddenly stop and fell into deep thought.

If you are an ordinary person, just these words will cause goosebumps on your back......
