On February 19, 3021, in the meeting room of the criminal investigation team, seeing that everyone had arrived, Jiang Chengyan said, "Everyone has arrived, then we will integrate the clues we have at present."
Seeing that everyone's attention was focused, Jiang Chengyan looked at Su Ke and said, "Su Ke, tell me about the autopsy first."
Su Ke nodded, opened the autopsy report, and said, "The deceased Liang Yijun, male, was 179 cm tall and weighed 70 kg. The cause of death was excessive blood loss caused by severing the radial artery. The time of death was between 10:00 and 11:00 on the evening of the 16th. It was verified that the murder weapon was the razor in the deceased's house. A large amount of alcohol was found in the deceased, and its composition was consistent with the red wine in the wine bottle placed outside the bathtub. In addition, sevoflurane was also found in the food in the deceased's stomach, which It is an inhalation anesthetic. According to the amount of drugs in the deceased's body, coupled with the effect of alcohol, the deceased can quickly enter a state of anesthesia. Combined with the weirdness of the deceased's wound, it can be further inferred that this case was a homicide, not a suicide ."
Jiang Chengyan nodded and said, "According to the situation at the scene, the deceased should have the habit of taking a bath and drinking red wine, and the murderer happened to know his habit, so he added sevoflurane to the red wine beforehand, and then while the deceased was anesthetized, The razor severed the radial artery of the deceased, giving the appearance of suicide, and then fled."
Su Ke echoed: "This is the most reasonable inference at present."
Jiang Chengyan looked at Qin An and said, "Qin Ke, what did you find there?"
"The door lock of the room is intact, there is no sign of damage, and the windows are also closed. In addition, his house is on the seventh floor, so the possibility of the murderer entering and leaving through the window can be ruled out. There are many fingerprints in the room, which can be confirmed at present, except for the deceased. , as well as Liang Zhaolan and Sun Ting. In addition, we also found a hidden secret door behind the closet of the deceased's bedroom, which placed a large number of sex toys, and found blood on the whip and needles of different lengths. and secretions, which have been identified as not of the deceased."
Jiang Chengyan asked aloud, "Is that Sun Ting's?"
Qin An shook his head and said, "No, there is no matching result yet."
"That said, what Sun Ting said may be true."
Yao Min asked curiously, "Captain, what did Sun Ting say? I heard that it wasn't Chen Miao who went to visit yesterday. Who did the captain go with?"
Jiang Chengyan's face was hot, and he said angrily: "Damn girl, you are the captain, I am the captain, do I still need to report to you when I do things?"
Yao Min said jokingly: "Oh, such a big reaction is obviously a guilty conscience of being a thief."
"Xu, you big-headed ghost!" Jiang Chengyan threw the notebook on the table and looked at the people around him who were laughing, and said, "We are in a meeting now, so give me some seriousness!"
Yao Min stretched out his hand to catch the notebook, holding back a smile and said, "Be serious, be serious. The captain said what Sun Ting said."
Seeing this, Jiang Chengyan couldn't help laughing, then coughed twice and said, "Sun Ting said that she and Liang Yijun have never had a sexual relationship."
Yao Min widened his eyes in shock and said, "What? This... It's not possible."
"It's not impossible." Su Ke continued: "From the things in his room, Liang Yijun has a habit of sex/abuse. This kind of person gets pleasure from sex/partner's pain, otherwise it will be difficult to get an erection. , having sex/relationships with people. And if Liang Yijun really had sex/relationships with Sun Ting, given the relationship between men and women, it must not be just one time, it is impossible to detect Sun Ting's DNA on those things. "
After Su Ke's remarks, everyone looked at each other in dismay. Only Su could have said such a private and shameful thing so frankly.
Jiang Chengyan coughed a little embarrassedly and said, "Well, Qin Ke, besides these, what else did you find?"
"In the bathroom, we also found some hairs, which belonged to the deceased and another woman, and the DNA on the sex toys belonged to the same person. The murder weapon only has the fingerprints and blood of the deceased, but the fingerprints are in the same position as a normal person. The knives are different, which can confirm Su Ke's conjecture. It should be someone holding the hand of the deceased and printed fingerprints on purpose. In addition, we also found a footprint at the door of the bathroom, size 43, which does not belong to the deceased. At present, these are the only findings. "
Li Tong guessed: "Size 43, male shoe print, appearing in the bathroom, this obviously does not conform to common sense, maybe it is left by the murderer."
Jiang Chengyan frowned and said thoughtfully, "According to the layout of the scene, the murderer is a thoughtful person. How could he leave a footprint, and it's only one, it seems a bit deliberate."
Li Tong said: "Captain, I think you think too much, there must be a sparse one hundred secrets, maybe the murderer left it by accident."
Jiang Chengyan was noncommittal, looked at Yao Min, and said, "What did you find there?"
Yao Min took out a photo from her notebook, stood up and stuck it on the whiteboard, saying, "Wang Ran, 26 years old, born on February 14, 2995, lives in Luohe Community, Bincheng. Due to family reasons, she went out after graduating from high school. Part-time job. She came to Huacheng two years ago and worked as a waiter in a coffee shop. Later, she was introduced to Heilan Trading by Sun Ting and became a clerk. The academic information she submitted to Heilan was forged. "
"Where is she now?"
"disappeared."
"Missing? When did it happen?"
Yao Min sighed and said, "I don't know exactly when. We asked our colleagues from Bincheng to investigate Wang Ran's information, only to know that Wang Ran had not returned home. His parents even asked about Wang Ran's whereabouts three times. They couldn't be contacted even after the shutdown, and they reported the missing to the local police station yesterday."
"Then when was the last time they contacted Wang Ran?"
Liu Ran followed suit with a sigh and said, "About three months ago. Wang Ran was adopted, and the couple from Bincheng are her adoptive parents. After marriage, she had no children for several years, so she went to the orphanage to adopt Wang Ran. Ran, Wang Ran's adoptive mother became pregnant unexpectedly and gave birth to a son, and she has ignored Wang Ran since then. If it wasn't for our investigation of Wang Ran's information, it is estimated that they would not know when they would have noticed Wang Ran's disappearance. Woolen cloth."
"Three months ago, after Wang Ran claimed to have been violated by Liang Yijun." Jiang Chengyan was silent for a while, then looked at Yao Min and said, "You contact the Bincheng police and ask them to help provide Wang Ran's DNA, and then hand it over to Qin Ke for investigation. DNA alignment."
Yao Min was startled, then reacted and said, "Captain, what do you mean, Wang Ran is the one who was sexually/abused by Liang Yijun?"
"It's just a guess at the moment, and it depends on the comparison results."
"Captain, I found Wang Ran's sex in Liang Yijun's laptop." Li Tong interjected, "Not only Wang Ran, but also the sex of five other women."
"The other five? Who are they? Do you have any information on them?"
"I haven't had time to investigate yet. Just when Yao Min took out Wang Ran's photo, I was sure that Wang Ran was one of them."
Yao Min scolded angrily: "Dead pervert, you deserve it!"
Jiang Chengyan glanced at her and said, "Girl, pay attention to your attitude, don't forget that you are a policeman."
"I know, as long as I'm not a policeman, I should applaud when such a person dies."
Jiang Chengyan shook his head helplessly, looked at Li Tong, and then asked, "How is the surveillance video investigation of Yihe Apartment, has the middle-aged man been found?"
"No, but we have confirmed his identity." Li Tong also held a photo on the whiteboard and said, "Gao Mingqiang, 53 years old, born on April 18, 2968, from Bencheng, divorced, has a Adopted daughter. Gao Mingqiang came to Huacheng to work three years ago, worked as a cleaner, and worked as a porter. He lives in Liujiazhuang in the east of Huacheng City. Because the information has just been passed, no investigation and verification has been carried out yet."
Jiang Chengyan nodded, looked at Guo Hai, and said, "Has the whereabouts of Liang Yijun been found out on the day of his death?"
"Liang Yijun went shopping with his friends in the morning, ate dinner together at noon, and then went to the game hall. When he returned home at 3 o'clock in the afternoon, his friend was with him until about 6 o'clock in the evening, when his friend left, Liang Yijun delivered it to him. Downstairs, then upstairs and never went out again."
"Did the people who went to his house follow up on their whereabouts?"
"It's implemented. Because it's New Year's Eve, we basically eat New Year's Eve dinner at home and don't go out."
"Is there anything else to add?" Everyone shook their heads one after another, and Jiang Chengyan continued: "Then I will arrange the next tasks. Li Tong, Zhang Liang, you and Wang Ran, the more detailed her information, the better. Including before she was adopted. Well, you go to Bincheng, Sun Ting and Gao Mingqiang are both from Bincheng, you can investigate in detail. "
"Yes, Captain."
"Yao Min, Liu Ran, you are responsible for finding the five women who were photographed and conducting interviews and investigations."
"Yes, Captain."
"According to Sun Ting, Wang Ran left the company on September 21. Chen Miao and Guo Hai, you go to the monitoring of Heilan Company, and then let the traffic control department cooperate to find Wang Ran's whereabouts that day."
"Yes, Captain."
"Wang Bin and me, go to Liujiazhuang to find Gao Mingqiang. Everyone will take their place and the meeting will be dismissed."
Everyone left one after another, but Jiang Chengyan did not delay, and drove to Liujiazhuang with Wang Bin, and came to the rental house where Gao Mingqiang lived. This is a farmyard, and there are many small rooms built in the yard, which are specially used for renting. Most of the people who rent here are migrant workers.
Wang Bin stepped forward and knocked on the door. After waiting for a long time, no one answered the door. He knocked several times in a row, alarming the neighbors who lived next door.
"Don't knock, I haven't seen him go out for two days. I guess he's going back to his hometown."
Jiang Chengyan pushed the door, frowned and said, "This door is obviously locked."
Jiang Chengyan walked around to the window, looked in through the gap in the curtain, and faintly saw a figure inside, his expression changed, and he said, "Wang Bin, hit the door!"
Wang Bin was stunned for a moment, then responded, stepped back a few steps and kicked the door ruthlessly. With the continuous heavy blows, the door was kicked open with a 'bang', and the small room was immediately clear at a glance.
There is a hook on the roof to hang light bulbs and fans, and under the fan hangs Gao Mingqiang's corpse. The cold wind blows and the corpse sways slightly.
"Oops, it's dead!" the next door neighbor yelled in fright.
Jiang Chengyan looked solemn, looked at Wang Bin and said, "Call someone."
Wang Bin hurriedly took out his mobile phone to make a call, notified his colleagues in the forensic department and the trace examination department, and by the way isolated the residents who were disturbed to watch the fun.
Jiang Chengyan put on his feet and gloves and entered the room, looked at the hanging corpse, hesitated for a moment, and called Ling Huaan.
