"Why?" Team Wang asked.

Ye Yinuo replied: "First of all, I have tens of thousands of genuine readers, this is not a small number, it is too difficult to investigate, and secondly, if the murderer is smart enough, he will definitely not go to my signing website to see, because this will be traced to the IP address, he will inevitably go to some pirated websites to see, the servers of those pirated websites are abroad, and the IPs are all virtual proxy IPs, there is no way to check at all, judging from the murderer's modus operandi, he is obviously not a fool." ”

Team Wang was stunned for a moment, looked at Ye Yinuo suspiciously, and asked, "Have you studied criminal investigation?" ”

"Sort of." Ye Yinuo smiled.

If it weren't for the delay in the case five years ago, Ye Yinuo would not have missed the opportunity to study in the investigation major of the Criminal Police Academy, maybe he would be a criminal policeman now.

Team Wang walked over and continued to ask while uncuffing Ye Yinuo, "Then what do you think about this case?" Where do we start? ”

Ye Yinuo loosened his wrist and said in his mouth: "The murderer must be someone Song Keer knows, he may be very familiar, this murderer should have a personality disorder or a very prominent personality trait!." ”

"Why?" Team Wang asked directly.

Ye Yinuo picked up the photos and said: "Generally, people who suffocate to death in the struggle have compression in the neck, the jugular vein is compressed, and the carotid artery and push pulse pressure are not closed, and the blood can only flow to the head, which will make the corpse's face swell, the lips will be purple, and the face will soon be pale, but her face is very calm and serene, and the Wang team should not be unaware of this." ”

Captain Wang nodded and said: "Then the forensic report should be sent soon, and the specific situation is still waiting for further confirmation, and I have always wondered why this happened." ”

"Because it's not ordinary asphyxiation, it's 'sexual asphyxia.'" Ye Yinuo said directly.

"Sexual asphyxiation?" Team Wang looked at Ye Yinuo in surprise, and didn't seem to have this concept.

Ye Yinuo explained: "Sexual asphyxia is also called self-Y asphyxia or self-Y death, using hanging, strangling and other ways to control breathing, causing the brain to be hypoxic, stimulating and enhancing its desire to achieve orgasm, when the brain is hypoxic, it will enter a lucid, semi-hallucinatory state, combined with orgasm, will produce a highly addictive feeling like D product, and this way is easy to have accidents, the accident is death, and there will be no superficial trauma to the body, but the cause of death is suffocation." ”

"I've been handling cases for more than ten years, and I haven't encountered this kind of thing, and I like to play such perverted things, so my personality traits are really prominent." Team Wang said in surprise.

Ye Yinuo spread his hands and said: "I just guess, now the time of death has been more than twelve hours, if the autopsy report shows that the corpse has not completely cooled and there have been corpse spots, and there is no bleeding under the conjunctiva of the eye, then Bacheng is a death of sexual asphyxiation." ”

Team Wang said and took out the phone of the letter and asked Dong Bingning when the autopsy report would come out, and then said into the phone: "Give me a few pieces of data first, corpse temperature, corpse spots, and whether there is bleeding under the conjunctiva of the eye." ”

Ye Yinuo hurriedly said: "Do another blood test to see how well fibrinogen is converted into Xianyuan proteolytic enzyme to see if it is lower than the ordinary value." ”

Team Wang nodded, retold what Ye Yinuo said, then hung up the phone, and said: "You kid can, you know a lot of professional knowledge, in the case of mental stress, fear, shock, and suffocation, fibrinogen in the blood will indeed quickly transform into lytic enzymes, if it is lower than the ordinary value, it is really not a normal suffocation death." ”

"Wait for the news, if it is really a death of sexual asphyxiation, then the direction of your investigation will be clear, the deceased and the murderer are very familiar, can take the initiative to open the door, take the initiative to have a relationship with the murderer, and can accept this perverted way." Ye Yinuo said calmly.

"In other words, what we are looking for is a man who is familiar with Song Ke'er and has a similar figure to you and has strong personality traits." After speaking, Team Wang nodded and thought, did not speak again, just looked at the air in front of him in a daze, and his expression was a little deep.

It didn't take long for a very young criminal policeman to walk in and say to Team Wang: "Master, the video processing results of the technical department have come out, and the back of the murderer in the video has indeed been covered!" ”

Team Wang was stunned, Ye Yinuo stood up in surprise, if the murderer's back had been treated, then his suspicion would still not be cleared.

Team Wang was not so nervous, he glanced at Ye Yinuo strangely, and looked at Xiao Dong, who was inserting a USB flash drive to retrieve the picture, and did not speak.

Xiaodong quickly took out a few pictures, those pictures were pictures of the murderer exiting Song Keer's room and leaving the corridor, the pictures have been sharpened by high-definition pixels, and they can be seen very clearly.

Xiaodong enlarged one of them and said: "The technical department has done a high-definition color RGB numerical comparison, and under the murderer's right shoulder blade, there is a regular circular skin-like local masking block, and there is a convex edge, which has been determined not to belong to the composition of the skin, it should be artificial skin." ”

Ye Yinuo breathed a sigh of relief, his back was full of scars, and there was only one place on the murderer's back that was masked, which directly proved that the man whose back was extremely similar to him Ye Yinuo in the video was not him.

Team Wang said that he knew, then turned his head to look at Ye Yinuo and said, "Congratulations, the suspicion is cleared, this grandson is smart but he was mistaken by being smart." ”

Ye Yinuo didn't have time to be happy, turned his head and asked Xiaodong: "Officer, I see that this artificial skin seems to be translucent, what shape can be identified by what it covers?" ”

Xiaodong nodded, clicked on a picture and said: "This is the physical characteristics of the murderer, the technical department has done relevant technical processing, and it has been preliminarily determined that it is a very regular circle, dark in color, the outside is a ring-shaped shape with an inner diameter of about one centimeter, and the inside is the shape of a skull, specifically a birthmark or a tattoo or a scar, etc., the current technical means cannot be fully identified, and it is guessed that it is a tattoo." ”

Ye Yinuo stared at the picture tightly, his fists crunched, five years ago, when the gang of bandits abused her, Ye Yinuo saw that they all had a tattoo in the same position on their bodies, round, and on the outside was a pale golden snake with its head and tail connected, the snake's head swallowed the snake's tail, and in the middle was a skull pattern, which was roughly similar to the shape in the picture.

Regarding this thing, Ye Yinuo investigated later, they are a very strange organization, that organization is called 'Snake Kiss Corpse', and that pattern is the totem of their organization.

Ye Yinuo doesn't believe in coincidence, if this murderer is really a person from the organization five years ago, then this is a premeditated frame-up against him, and his reader Song Keer is just a scapegoat.

But if it was really framed, it was impossible for them not to know those scars on Ye Yinuo's back, why did they reveal such low-level flaws?

No, Ye Yinuo was shocked in his heart, knowing that the five bandits with the scars on his back were all dead, and others may not know, thinking about it this way, this framing was still a premeditated frame-up. And this kind of framing must have come from that organization's revenge on Ye Yinuo.

"Ye Yinuo, what's wrong with you?" Seeing that Ye Yinuo's face was wrong, Team Wang asked with some confusion.

Ye Yinuo looked at Team Wang, but didn't say anything about it, and forced a smile and said, "It's okay, I just hate this grandson." ”

As she was talking, Dong Bingning walked in, she handed a document to Team Wang and said, "This is a preliminary autopsy report, and the conclusion given by the forensic doctor is indeed suffocation, but it is not normal suffocation." ”

"The corpse is frozen behind the corpse spots, the eye conjuncture membrane is not bleeding, and the value of invertase is five times lower than the standard value of the corpse, you are all right, it is indeed a death of sexual suffocation......" Team Wang looked at the document and muttered to himself, and then stared at Ye Yinuo incredulously.

Dong Bingning looked at Ye Yinuo suspiciously, and took the initiative to say: "Team Wang, can I participate in the detection of this case?" ”

Team Wang thought for a while, shook his head and said: "No need for the time being, now the direction of the investigation of the case is very clear, through monitoring and investigation, and after a few visits, you can lock the target and arrest it." ”

Ye Yinuo snorted and said, "Is that asking someone to take me for a scar evaluation, and I can leave?" ”

Ye Yinuo said this in his mouth, but he didn't think much of what this Wang team said, he had contact with the people of that organization, they were not ordinary criminals, even if he had these information now, it was not so simple to catch the murderer.

Team Wang nodded, "Yes, Xiaodong, you take him to the forensic office for a scar evaluation, and ask Er Fat to give me a certificate." ”

Ye Yinuo turned around and walked towards the door, and when he passed by Dong Bingning's side, he looked her up and down playfully, and suddenly stared at her seriously and said, "You owe me a meal, what is your mobile phone number?" ”

"1384739XXXX" Dong Bingning said subconsciously, that Xiaodong and the Wang team were stunned, even Dong Bingning was stunned after speaking, she asked again: "What ...... in your eyes just now?"

Ye Yinuo smiled, turned around and walked out of the interrogation room, Xiaodong followed, and muttered: "Brother, you are really capable, Sister Bing will never tell others her private mobile phone number, even if it is a colleague in the team, she will not reveal it easily." ”

"Maybe it's because I'm so handsome." Ye Yinuo said jokingly and walked towards the elevator at the end of the corridor.

Xiaodong smiled, "It's not to brag to you, an excellent man who wants to chase Sister Bing, can line up from the east of the city to the west of the city, and there are more handsome than you, she will never be like this." ”

Ye Yinuo no longer answered, that organization finally appeared, and his mission came.

Ye Yinuo followed Xiaodong to the forensic laboratory on the negative floor, and as soon as he arrived at the door, a smell of formalin came to his nose, including various pungent chemical smells, this kind of place, only specially trained people can stay for a long time, but this is nothing to Ye Yinuo.

This forensic laboratory is a little rudimentary, surrounded by some instruments, a desk in the corner of the northeast corner, there are two dissecting beds in the middle, and Song Keer's body is parked on the bed outside, naked, the private parts have been covered by a white cloth, a faint bruise can still be seen on the neck, and a small number of corpse spots have appeared on the surface of the corpse.

On the dissecting bed next to it, there was a male headless corpse that had been divided, the corpse had undergone preliminary treatment, and the corpse pieces were spliced together with sutures, the abdominal cavity and chest cavity had been completely opened, and the bloody internal organs inside could be seen, the corpse should have been dead for more than three days, although it had been embalmed, but there was still a strong smell of corpses in the laboratory.

The naked corpse was almost naked, not even a corpse cloth, Ye Yinuo habitually looked at the fingers of the corpse, the nail cracks had been cleaned, and on the middle finger of his left hand, Ye Yinuo saw a silver ring, due to the puffiness of the corpse, the ring was almost embedded in the flesh, even so, Ye Yinuo still saw clearly that there were two very small letters engraved next to the shank: KR.

Those two letters were very small, and under the infection of bloodstains, Ye Yinuo could barely see the two outlines clearly.

A fat man who looks extremely honest is eating instant noodles at his desk, wearing blood-stained gloves on his hands, eating ugly and sloppy.

"Huh? Xiaodong, why are you here? The fat man saw Ye Yinuo and Xiaodong coming in, and walked over while eating with a bucket of noodles.
