Case closed

The police officer on duty opposite responded: "Captain Jiang, what happened."

Jiang Shan: "There was a murder case at the pure-tone KTV on Xinsong Road. Chief Situ of the forensic department was with me. You go to the forensic department and bring Chief Situ's toolbox. By the way, send someone to drive over. Bring the body back." "Okay."

Jiang Shan continued to ask the KTV staff, "Where is the body, whoever found it first."

Next to the KTV foreman that day, there was a man dressed as a cleaner, holding a broom, and said, "Police, it's me...in that men's room."

Jiang Shan and his group followed the cleaning man to the men's toilet of the KTV. The door was closed, and there was a "cleaning" sign on the door. After Jiang Shan opened the door and went in, he saw a naked woman lying on the ground with scattered some clothes.

Situqian and Xu Yi went up to check the corpse, because they were out to play, and there were no tools at hand. Situqian barely used a tissue to separate them, and probed the woman's artery. She was indeed dead, but the tentacles were still warm. , The bathroom is relatively dark, and the cold floor has a cooling effect, Situ Qian got up: "It is estimated that the time of death is less than an hour."

Jiang Shan nodded, and could only be on guard, evacuating the waiters who were watching, and Gu Lang went to the front desk to get the surveillance video of this KTV tonight, but the waiter in charge said that only the lobby of this KTV has surveillance video, and the surveillance in the corridor is all In addition to the main entrance, the KTV has another exit, which is connected to the supermarket, and the exit of the supermarket will undoubtedly increase the difficulty of solving the case.

Jiang Shan looked around, "Why are there no shoes for the deceased?" Then he turned and asked the foreman, "Do you still have any memory of the customer who came today? Do you know which private room this girl is probably from?"

The foreman shook his head, "Tomorrow's weekend, there are usually a lot of customers tonight, and many customers come directly from other people's private rooms. We don't know for sure."

Situqian and Xu Yi guarded the corpse, and Jiang Shan and Zhou Ying went to the private room on this floor to check. Because someone died in the KTV, most of the guests left in panic, but ordinary customers should not leave their money and shoes , See if you can find the deceased's ID and shoes in the private room.

After people came to the team, Xu Yi and Situ Qian took the corpse back first, and the technical team came to take pictures to collect evidence, and everyone returned to the team with a corpse to continue working overtime.

The things around the dead body were undocumented, only clothes, a white suspender top, a super short wrap-around skirt, a pair of invisible bras, and a pair of lace underwear. The deceased wore heavy makeup, and his fingers and toes were dyed bright The nails and hymen were old and broken, and there was male body fluid in the lower body, and DNA testing was needed to see if only one person had sex with the deceased.

Gu Lang has been watching the video brought back from the KTV. The video shows that at around 08:30 in the evening, the woman entered through the main entrance of the KTV accompanied by a man, but when the crowd dispersed, she did not enter through the main entrance. Surveillance saw the man, who may have left through the back door.

Zhou Ying found a pair of shoes of the deceased in the door of the women's bathroom. Jiang Shan found a lady's handbag from a private room. According to the photo of the ID card in the handbag, it was indeed somewhat similar to the deceased. Jiang Shan was at the front desk. After finding out the mobile phone number that booked this private room, Jiang Shan asked Zhou Ying to check the number after returning to the team.

At nine o'clock in the morning, Jiang Shan went to the forensic anatomy room. Jiang Shan stared at the face of the deceased in a daze. Situ Qian looked at him, "What's wrong with you? Have you identified the source of the corpse?"

Jiang Shan nodded: "You still remember the case of Cha Shishan, I told you about a case. Eight years ago, when I was finishing my graduate study, I practiced with a teacher in Ningyuan. There was a 15-year-old girl , because she fell in love with a little gangster, her mother was hacked to death, and it was her."

Situ Qian was a little surprised, and Jiang Shan continued: "That was the first case I came into contact with as an intern in Ningyuan. The make-up on the corpse was so heavy that I didn't recognize it at all. I just saw the photos and information on her ID card. , I just remembered."

Situ Qian was a little surprised, "Well, the autopsy is basically done, and the blood sample test is still left. Xu Yi has just sent it over, and it may take a few hours to get the results."

Jiang Shan nodded, "Let's go, we have a meeting in the conference room and sort out the clues."

meeting room.Jiang Shan briefly introduced the situation of the deceased: "The name of the deceased is Yang Jingjing, 23 years old, her parents divorced, her mother was killed and died eight years ago, and she takes living expenses from her father every month to maintain her life. The family relationship is relatively simple, but due to the experience of losing her mother Cracked down, and no one disciplines her, Yang Jingjing dropped out of high school after graduating from high school, and mixed with some social youths, her social relationship is more complicated, Situ." Jiang Shan motioned Situ Qian to talk about the autopsy.

Situqian: "The time of death of the deceased was between 11:[-] and [-]:[-] p.m. on June No. Apart from the pinholes left, there are no other pinholes in the body, and the cause of death is preliminarily determined to be the initial intravenous drug overdose, resulting in depression of the respiratory center and sudden death."

Jiang Shan: "What's the matter with the naked state of the corpse?"

Situqian: "There are many fingerprints on the deceased's body, etc. After checking, they are not the deceased's own, and there are male bodily fluids in the lower body of the deceased. The DNA of two people has been extracted. For the time being, the corpse knows these."

Jiang Shan asked: "We also found a 5ml syringe next to the corpse. Have you checked the fingerprints on it?"

Situqian: "There are fingerprints on the needle barrel of the syringe. After investigation, it is not the deceased's. It does match the fingerprints on the deceased's body. However, it is not known whether the deceased was forced to inject drugs intravenously or voluntarily. .”

Jiang Shan keenly noticed the syringe barrel that Situqian only mentioned, "Are there fingerprints only on the barrel? What about the piston rod? There should be a thumb's fingerprint on the top of the piston rod."

Situqian: "That's the problem, but there are no fingerprints on the piston rod, but I thought, maybe the other party is wearing gloves when injecting, or the thumbprint is missing due to other reasons."

Then Gu Lang got up and released a video, "The deceased entered this KTV with this man that night. In addition to the large tattoo on his left arm, this man also had a small tattoo on the back of his neck. I think the tattoo can be removed." The pattern is used as a breakthrough, check it out."

Jiang Shan nodded: "Zhou Ying, what about the technology side?"

Zhou Ying: "According to the information about the private room where the deceased's handbag was found by the Gu team, we got the mobile phone number that opened the private room. The registrant of the number is Li Yao, who works in a textile factory and lives in Heyuan Community, and the deceased's handbag contained a mobile phone number. The last phone call displayed, the note is "brother", this number is not registered with a real name, and the owner cannot be found."

Jiang Shan: "The home and garden are all tenants."

Jiaheyuan is a small apartment building with two bedrooms and one living room. It is located in the suburbs. It belongs to the government-built rental community for low-income families and those who come to the city to work.

Jiang Shan assigned the direction of investigation: "We must first find this man named Li Yao and the so-called younger brother of Yang Jingjing, for example, people in society who are regarded as siblings of the deceased, and see if the person who entered the KTV with Yang Jingjing in the video is not the same person. , Gu Lang, you can check this part." "Okay."

"Situ, do you know what kind of drug the deceased injected before his death?"

"The deceased was injected intravenously with the traditional drug cocaine, but it is uncertain whether it is the same type as the deceased's daily drug. Xu Yi has already sent for a blood test, and the results will be available soon."

Gu Lang went to the Jiaheyuan Community to find Li Yao, the resident who was enthroned and moved in.This Li Yao looked like an honest worker, but Gu Lang looked up at his arms and neck, Li Yao didn't have any tattoos.Gu Lang took out Yang Jingjing's photo and asked if she knew her.

Li Yao nodded: "Well, it's my girlfriend."

Gu Lang: "Where were you between nine o'clock and ten o'clock last night, is there anyone with you, can you testify for you?"

Li Yao: "I work in a factory. I went to middle shift yesterday, from four in the afternoon to twelve in the evening. The workers with me can prove it."

Gu Lang: "Then why did you open a private room at the pure tone KTV on Xinsong Road last night?"

Li Yao: "My girlfriend said she wanted to get together with her friends tonight, and asked me to book a private room for her, so I did it for them."

Gu Lang: "Then do you know who is with her?"

Li Yao shook his head, "I'm not very clear about this, and I actually can't remember her friends." Then he thought for a while, "But there is one who has the best relationship with her. Usually, when my girlfriend talks about going out to play or something, With her."

Gu Lang: "What's the girl's name and where does she live?"

Li Yao: "My name is Ding Li. I don't know where I live, but I work in that big supermarket two blocks away. She seems to be a cashier." Li Yao became a little anxious after speaking, "Officer, is that my girlfriend? What happened, has she been arrested?"

Gu Lang was stunned for a moment, Li Yao didn't know the news of Yang Jingjing's death, but he didn't know if he really didn't know or if he didn't know, he had to blow up again, "She...your girlfriend was just..." Gu Lang was deliberately vague He spoke slowly.

Li Yao frowned, "Did she take drugs again?"

Gu Lang froze for a moment: "Do you know about her drug use?"

Li Yao nodded: "She used to take drugs before, but after being with me, I sent her to a drug rehabilitation center, and after she came out, she promised me that she would never touch drugs again."

Gu Lang was a little messy, and looked at the man in front of him resentfully, "Uh, does your girlfriend have any younger brothers, relatives, or men in social relations who are called her siblings?"

Li Yao thought for a while: "No, my girlfriend's mother passed away a long time ago, and her father reorganized the family. Her father has a younger brother who is in elementary school, but after she became an adult, her father stopped giving money, and she didn't get along with her. I've contacted her father," Li Yao continued, "I don't know much about her social relations, probably not."

Gu Lang nodded, said "excuse me" and left.
