Zhang Lanshan saw Jiang Chonglang's actions, gave him a blank look and said: "When people are in the absence of oxygen, they will feel excited, including sexual pleasure. So some people like to use binding or strangulation to increase pleasure during the XXOO process, and that's the reason, and it doesn't say anything. ”

At this time, other police officers were searching the deceased's inner room, and as a result, a large number of photos of naked men and naked women were found in the deceased's computer, as well as hundreds of Japanese action romance movies, and various masturbation tools were found at the deceased's bedside. Jiang Chonglang found the identity card of the deceased, whose name was Gu Yongzhen, who was 31 years old this year.

Jiang Chonglang took out Gu Yongzhen's mobile phone in the drawer again, and found many selfies of the deceased inside, and even photos of naked sexual organs. Jiang Chonglang looked through the text messages, WeChat, and communication records in his mobile phone again. said: "It seems that eighty percent of the deceased's occupation was a male prostitute. ”

Immediately afterwards, Jiang Chonglang turned his gaze to the deceased's bed, and the messy and wrinkled sheets showed that not long ago, there should have been a cloud and rain on it. I walked to the bathroom and found several sex tools in the bathroom, including tools for SM. Jiang Chonglang frowned, and when he was about to leave, he looked up at the ceiling above the bathroom, "Huh", Jiang Chonglang felt a trace of doubt in his heart.

At this time, Han Yuchao walked over, "Brother Chong, just now I made a record of the case handler and the neighbors around the deceased. The aunt who reported the crime and the deceased did not know each other, they lived on the same floor of two buildings not far from each other, and the aunt said that as soon as she got up early this morning and opened the curtains, she saw the deceased hanging in front of his eyes on the opposite building. The deceased was said to have worked in a nightclub, danced striptease, and also engaged in carnal trade. He was often seen coming home with different people. "Among them are women and men, old and young, and sometimes it is said, and blacks, and whether there are people who are not people." ”

Jiang Chonglang nodded, asked Han Yuchao to take the sheets for testing, and at the same time took off the long towel that Gu Yongzhen had hanged and put it in the evidence bag.

This long towel looks very similar to the long towel that Ren Mingtao used to hang himself. And on this long towel, Jiang Chonglang smelled the familiar fragrance again, which was very similar to the smell on the long towel that Ren Mingtao committed suicide with. These long towels can be bought anywhere. So there's nothing special.

Dissecting a cadaver is a long and boring process, at least from Jiang Chonglang's point of view. He didn't understand why Zhang Lanshan was so excited about dissecting corpses. Soon, Zhang Lanshan provided Gu Yongzhen's autopsy report: Gu Yongzhen's time of death was between 10 o'clock and 12 o'clock on December 26, and the cause of death was suffocation caused by hanging. As for whether it was suicide or homicide, Zhang Lanshan said that in terms of autopsy, I am afraid he still prefers the former. The reasons are exactly the same as those at the time of Ren Mingtao's autopsy: 1. The ditch on the deceased's neck was indeed caused by hanging, and the character of the ditch on the neck was the same as that of the long towel at the scene of the crime; 2. The deceased did not have any injuries left by violent confrontations with others; 3. The injuries on the deceased's ditch had a vital reaction, which can prove that it was hanged rather than hanging after death.

Xu Meng said that the occupation of the deceased had been determined, as expected. Gu Yongzhen is a nightclub waiter on the surface, but he is actually a male prostitute behind his back. He also often takes large-scale photos for some light color magazines, and has had affairs with many men and women of different ages, but it is said that recently because of money problems, he has a very bad relationship with some of his "old customers", saying that he wants to make some of his indecent photos public.

Linking these two cases, the police officers of the serious crime team all felt that there were some problems: 1. When the deceased hanged himself, he actually used the same long towel; 2. Both deceased had sex before they died, and several women's hair and dander fibers were found in the sheets on Gu Yongzhen's bed.

There is also a very important suspicion, which is given by the traces department: the same perfume ingredient was found on the two long towels used by the two deceased to hang themselves, from a French brand.

Some people believe that these are two suicides, the deceased did commit suicide, there were no signs of other struggles at the scene, and there was no sign of dragging on the deceased's body, but the deceased was indeed hanged by a long towel found at the scene; However, there are also some people who believe that in both cases, the long towels of the hanged deceased were stained with the same brand of women's perfume. This may not be a coincidence, it is very likely that the same woman appeared at the time of both crimes. This woman had sex with both of the deceased, and I am afraid that the deaths of both of them were related to her. In the end, Jiang Chonglang made a decision: find the woman first, and then make a decision.

A woman has had sex with two men, one of whom is still a male prostitute. Then this woman is a prostitute. Jiang Chonglang decided to start with the social relationship between these two men. Among them, Gu Yongzhen's social relations are miscellaneous and there are many clues, but it is difficult to investigate them one by one, so it is better to start with Ren Mingtao.

Han Yuchao and Shen Bin went to Hu Yanzhu again to understand the situation, and now Hu Yanzhu has moved out of the original community and lives with his parents. After Ren Mingtao's death, Hu Yanzhu and his unit proposed to take a temporary leave for a month to calm down.

Hearing the police's intention, Hu Yanzhu was surprised. She said that if Ren Mingtao was killed, she would definitely help find the murderer.

Han Yuchao asked: "How is Ren Mingtao's private life, does he often go to places like bars and nightclubs?" ”

Hu Yanzhu thought for a while and said, "Before he didn't know me anymore, he often went to that kind of place with his friends. But after he got to know me, he didn't go there very often. ”

Shen Bin then asked: "Has he been there recently, is there a young lady who has a good relationship with him or something?" ”

Hu Yanzhu shook his head: "I don't know, since he met me, he hasn't been in contact with those people." ”

Han Yuchao suddenly remembered that Hu Yanzhu had said about Ren Mingtao and his ex-girlfriend last time, so he asked: "You said about his contact with his ex-girlfriend." Have you ever met his ex-girlfriend? ”

Hu Yanzhu shook his head: "No, after I confirmed the relationship with him, I forced him to delete everything about him and his ex-girlfriend." But he said two months ago, he said he met his ex-girlfriend during a check-up and spoke with him on the phone several times. I thought there was something between them and quarreled with him a few times. Now that I think about it, it may have been to borrow money to make up for his losses in the stock market. ”

During the physical examination, it should be in the hospital, Jiang Chonglang asked, "In which hospital?" ”

"Yangcheng X Hospital." Hu Yanzhu replied.
