Tang Yan placed these confidential documents on the coffee table in the room so casually, obviously trying to test me.

Remembering what Lao Yan told me before, I hurriedly withdrew my gaze, and then slowly sat down in my position.

When I raised my head again, I happened to see Tang Yan's pair of sharp gazes falling on me, and then nodded slightly meaningfully: "It's okay, those documents were originally prepared for you, just read them if you want to!" ”

seems to be a casual sentence, but it invisibly carries a huge sense of oppression. Only the man in front of me, with the knowledge I had learned in the past, could not see through him at all.

is worthy of being a well-known behavioral polygraph analysis expert in the criminal investigation field, and it is conceivable that those criminals who were interrogated by Tang Yan in the past had to undergo a psychological test.

Taking a deep breath, he forced himself to empty his brain, and then looked at Tang Yan in front of him and said slowly: "Officer Tang laughed, such a confidential document, how can someone like me look through it at will, please put it away as soon as possible." I don't know what happened when Officer Tang came to me this time? ”

I haven't finished my words yet, but I didn't expect Tang Yan in front of me to be happy first.

"What's the matter? Of course, I'm asking you to solve the case. If I'm not mistaken, Comrade Gao Fei was the most potential student of Z University, and I believe that you should also have your own unique views on this strange skinning case! As soon as Tang Yan finished speaking, he took a cup of chrysanthemum tea and slowly walked in front of me and sat down.

"If I'm not mistaken, you and that old guy Yan Shusen are here for this case! So, without further ado, tell me your thoughts on this case! ”

Tang Yan grabbed the conclusion report and slowly handed it to me.

Printed on the report are reports of the traces of the crime scenes of the two murders and the analysis of forensic conclusions. This is also something that Lao Yan could not provide to me before, after all, these reports are confidential documents of the Jing'an Port Municipal Bureau, and they must not be circulated until the case is solved.

Strange, so weird!

I couldn't understand why the police officers at Jing'an Port had gone to great lengths to prevent me and Lao Yan from intervening in the skinning case. But now, Tang Yan can take the initiative to hand over this confidential document to me so confidently.

Could it be that Tang Yan really didn't know about the behavior of Da Liu and others before. In terms of solving the case, he is actually not on the same front as Cheng Zhimin, Da Liu and others.

Or is it that Tang Yan concluded that I had the ability to solve the skinning case, so he was so relieved to hand over the conclusion report to me?

I hesitated, but quickly took the report and read it carefully.

I have to say that the details mentioned in the document in front of me are much more complete than what Lao Yan told me before. Through the details of this, I also roughly understood why the police would focus on Lu Yuan's primary target.

First, let's talk about the case of Mountain Eagle. From the results of the forensic records and the identification of the traces of the present death, the following details can be approximated.

The first point is that although Shanying was skinned, the real cause of his death was indeed mechanical asphyxiation.

The police extracted a small amount of blue pigment and some kind of plant fiber near the skin pocket on the neck of the mountain eagle, and there was a slight bone crack on the back of the neck of the mountain eagle. It is preliminarily inferred that the murderer should have strung him to death from behind after bypassing the neck of the mountain eagle with a blue-colored string.

Although the entire skin is torn off, when a person dies, the blood stops flowing. Therefore, the police still found different degrees of contusions on the palms, arms, and legs of Shanying.

In the forensic report, there was no sign of poisoning, head damage, or binding of hands and feet. This means that the murderer should have strangled the mountain eagle to death without any restraints.

Mountain Eagle has a background in the underworld, and at that time, he participated in many gangs and firefights. This somewhat means that the guy still has a certain ability to fight in close quarters, and he is very vigilant. If it is a stranger, it is not easy to approach him from behind and strangle him directly.

Based on the above details, the members of the Traces Investigation Bureau believe that the murderer should have known to Shanying beforehand. Moreover, the murderer should be an adult male, over 25 years old, with a strong physique, and a strong psychological endurance, with a certain amount of anti-reconnaissance ability.

Through the conjecture that the deceased had struggled violently before his death, the police examined the palms, nails and other parts of the mountain eagle in detail. Because when the neck is strangled and unable to breathe, the human instinct will dance uncontrollably and attack everything that can be attacked as best possible in order to regain breath.

To take the simplest example, there are many people who have drowned, and their fingernails are often stuffed with black mud or even aquatic plants.

Based on the efforts of the members of the Traces Identification Bureau, the police extracted all five fingers of Shanying's right hand from human skin tissue. After identification, the extracted skin tissue was obviously inconsistent with Shanying's own.

Therefore, the skin tissue in the cracks of Shanying's fingernails is very likely to be left by accidentally catching the real murderer during the near-death struggle. If nothing else, the DNA results of the skin tissue should be exactly the same as Lu Yuan. And before Shan Ying's death, there were people who witnessed a violent conflict between him and Lu Yuan.

To sum up, it is completely enough for the police to define him as a suspect and arrest him with all their might.

I guess it is precisely because of these clues that when Team Leader Wu was investigating the case, he dared to let go of his big words, saying that he wanted to arrest the murderer within a week. I never thought that it was this sentence that pushed Team Leader Wu into the abyss of no return.

Team Leader Wu may not have really figured out what kind of fierce character the murderer he faced this time was until he died.

After reading this, I closed my eyes, slowly rubbed the part of my eyebrows, and then carefully recalled the whole case in my mind.

Contusions on the skin of the eagle are mainly concentrated in the right leg and near the right upper arm, and a small amount of bruising is also found in the musculature near the right shoulder. This means that during the strangulation of the mountain eagle, the murderer may have fallen to the ground with him. In general, when both hands exert force at the same time, the strength of the right hand will be significantly higher than that of the left hand.

Excluding the abnormal situation in the process of fighting, if the right hand is obvious, then the mountain eagle is pulled by the force, and the left side should land first. Judging from the results of the forensic examination, the guy flipped to the ground along the right side, which means that the real murderer's dominant hand is most likely the left hand.

In an instant, the scene seemed to come back to me. I seemed to see a guy dressed in red, holding a light blue rope, slowly approaching the mountain eagle from behind。。。。。。

Through these appraisal reports provided by Tang Yan, this time, I can be considered to have completely figured it out.

Originally, I was worried that Lu Yuan would kill the "Mountain Eagle" by mistake because he lost control for a while. Now it seems that the murderer could never be him. There is a bastard guy hiding behind the scenes, using all kinds of means to try to fake the illusion that Lu Yuan is killing people.

After a while, Tang Yan glared at me and said slowly, "Have you finished reading?" You've only seen the first case, about Team Leader Wu, but you still haven't moved at all? ”

"Just look at this one, it's enough!" Besides, my body has just recovered a while ago, and if I receive too much information at this time, my brain may not be able to bear it.

"Why?"

"Because apart from the fact that the murder methods are the same, I don't think there is much connection between the two murders, and the result of the police merger is likely to be a mistake from the beginning!"

"Oh? Is it. Tang Yan deliberately showed a surprised expression, and then sat up slightly straight, I feel that this criminal investigation expert has finally begun to officially talk to me.

"According to what you say, then what about your friend Lu Yuan, do you think he killed Shanying or Team Leader Wu?"

Haha, Officer Tang, I don't think Lu Yuan is guilty, after all, I am confident enough to make you accept my analysis later.

Besides, since you are coming here today, I believe that in your heart, you must have the same opinion as me.

Lu Yuan is innocent, the real murderer is someone else, and the murderer is somewhere now, watching the police's every move!
