"At about 8 o'clock yesterday morning, four bodies were found at No. 16 Shuangqing Lane, Dongguan Street, Yongchuan Town. The person who reported the case was Lu Chunsheng, the brother-in-law of the head of the household, Chen Zhiping, and the brother of the hostess, Lu Chunyan. According to Lu Chunsheng, he planned to go to his sister's house yesterday.

My brother-in-law stopped by to give my sister some fresh vegetables grown at home, but no matter how hard I knocked on the door, no one came.

When he called his sister's husband, his phone was turned off. When he called his nephew Chen Mo, Chen Zhiping's son, his phone was also turned off. Lu Chunsheng was a little worried, so he climbed over the wall and entered the courtyard. Looking through the window of his sister's bedroom, he found a large number of things on the wall.

There were dried blood stains and there was a body in the house, so the police were called immediately."

“The local police station in Yongchuan Town immediately reported the situation to the Municipal Bureau. Since the bureau leaders and Team Li were participating in activities in Yongchuan Town at the time, the bureau leaders took command nearby and asked local Yongchuan police officers to protect the scene. All members of the Municipal Bureau’s criminal police team were on duty and arrived in Yongchuan.

Join Team Li and specially approve Teacher Du and Dang Hui to participate."

"My name is Mo Anran now." Li Xian interrupted.

"Oh, I'm sorry, I forgot." Qu Mingming smiled apologetically at Mo Anran, and Mo Anran waved her hand to indicate it was okay.

"Two of the four deceased were buried in the cement pond where the family stored radish and potatoes. They were highly decomposed and almost impossible to identify. By recovering the mobile phones on them, it was confirmed that they were the head of the household, Chen Zhiping, and his wife, Lu.

Chun Yan, and no mobile phone was found on the body on the floor of the bedroom, it is initially speculated that it is his son Chen Mo. The reporter identified the body found in the water tank in the warehouse as Chen Chen, the daughter of the head of the household and his wife."

"The cause of death of the two corpses in the kitchen was excessive bleeding after being chopped with a sharp weapon. The shape of the murder weapon blade was extracted from the arm bones of the deceased, which was consistent with the kitchen knife found in the east wing. The other corpse was found in the bedroom.

There were also knife-like wounds, and Chen Chen had a strangulation mark on his neck. It was initially determined that he died of suffocation."

"Let's talk about the distribution of evidence at the scene." Qu Mingming pulled up the whiteboard, which had a sketch of the crime scene. "There are eight buildings on the scene, including Chen Lu and his wife's bedroom on the east side of the main house, and Chen Chen's bedroom on the west side of the main house.

bedroom, the main room between the two bedrooms, the kitchen behind the main room, Chen Mo’s bedroom in the east wing, and Chen Mo’s bedroom in the west.

The room of the wing tenant Yu Dalong, the east warehouse and the west warehouse. Judging from the on-site blood stain analysis results, the first scene of the murder of the two bodies found in the kitchen should be the bedroom of Chen Lu and his wife, and then the murderer moved the two bodies

He was buried in the vegetable sink in the kitchen, and there was no sign that the body in the bedroom had been moved."

"Chen Chen was violated and murdered in her own bedroom. A shoelace was found on the bedside, which was about the same thickness as Chen Chen's.

The marks on Chen Chen's neck were consistent with each other, and it was initially determined that it was the murder weapon used to kill Chen Chen. The component of sodium hypochlorite in YD of the deceased was detected, and it was suspected to be 84 disinfectant. Due to the strong oxidation effect of sodium hypochlorite, the J in YD

No DNA can be detected from the Y residue. Sodium hypochlorite was also detected on the floor of the east warehouse. It should have been spilled by the murderer when he poured 84 disinfectant into Chen Chen’s YD in the warehouse. Also, the murderer was very cautious and cleaned up all

Fingerprints, or in other words, he simply committed the crime while wearing gloves."

Li Xian said: "Tell me about the suspect."

"Okay, it has been initially determined that Yu Dalong, the tenant who rented the west wing, is suspected of committing a major crime. Yu Dalong, male, 29 years old, worked for a cleaning company in Yongchuan Town before the crime, and was engaged in B&Bs in Yongchuan Town.

Outsourcing daily cleaning, to put it bluntly, it means cleaning the B&B

, the cleaning company is not very formal. It didn’t even keep Yu Dalong’s ID information, and it is still being investigated. After the incident, this person lost contact, and Yu Dalong’s mobile phone is currently turned off. And we are in Yu Dalong’s room.

A small half-barrel of 84 disinfectant was found inside, and there were no fingerprints on it."

"Can the time of the crime be determined?" Li Xian asked.

Wang Jieshu replied: "We asked the surrounding neighbors and they reported that the last time they saw the family was on the morning of the 3rd of this month. Chen Chen's classmates said that the 3rd was Sunday. Chen Chen did homework at his classmates' house in the afternoon and returned by himself around four o'clock.

Home. Chen Chen’s class teacher said that around 9 pm on the 3rd, Chen Zhiping once gave Chen Chen’s class

The director sent a message asking for sick leave for Chen Chen. However, we speculate that Chen Zhiping should have been killed at that time. This message is believed to have been sent by the murderer using Chen Zhiping’s mobile phone. Based on the above information and the results of Shui’s forensic autopsy, we

Preliminary judgment is that the time of the crime should be from the afternoon of the 3rd to the early morning of the 4th."

"Forensic Doctor Shui, tell me about the autopsy." Li Xian turned to Shui Guochang.

"The two corpses found in the kitchen were buried in the soil, so they were in a serious state of decay. The skin, muscles and internal organs were basically decomposed. The injuries could only be judged by wounds deep into the bones. The clavicle of the female deceased Lu Chunyan

He was injured by a kitchen knife. Judging from the position, this knife should have severed the carotid artery, causing massive bleeding. This single knife is enough to kill the man.

The deceased Chen Zhiping had multiple defensive wounds on the radius of his arm, a knife wound on his sternum, and multiple knife wounds on the front and side of his skull. It was initially judged that he died of excessive bleeding. Another male deceased, Chen Mo, was in the bedroom.

, there was a knife wound on the back of the head, but the width of the wound should be the back of the knife, not the blade. There were signs of massive subdural bleeding in the brain at the wound site, which should have been caused by a knife.

The back of the kitchen knife hit the back of the head hard, causing a dural hematoma. The hematoma later ruptured and led to death. Residues of 84 disinfectant were also detected on the body. Because of this, although the body was rotten, maggots did not appear.

The situation just happened

Qu Mingming has already introduced it. Let me add a few more words. In addition to a deep strangulation mark on the neck, there is also a layer of bruises caused by pinching the neck with both hands below the strangulation mark. There are also several bruises on other parts of the body.

There are life reactions, which are caused before death."

"Dr. Du, please tell me about the blood analysis."

Du Lin did not drink the blood this time, because the time of death was obviously more than twenty-four hours, and there would be no "phantom" when drinking the blood, so the blood was tested by instruments. Fortunately, he can also use these instruments.

use.

Du Lin asked Mo Anran to turn on the projector, and the policeman sitting by the window closed the curtains. "Since many of the blood stains at the scene were mixed, I checked different locations on the scene and extracted 35 relatively independent sets of blood samples, each belonging to

5 people.”

Du Lin said while using the remote control to switch the pictures on the projector, "The splatter-like blood stains caused by arterial spray on the mattress, quilt and wall in the east bedroom belong to Lu Chunyan, the wife of the head of the household. This is also consistent with the autopsy results of Shui Forensic Examiner.

It coincides with the fact that part of the pool of blood on the ground also belongs to her."

"Throwing blood stains on the floor, walls and furniture belong to Chen Zhiping. They should have been caused by the murderer slashing at Chen Zhiping multiple times, and the blood on the knife was thrown out. There were two small amounts of blood stains at the door of the bedroom, which belonged to Chen Mo and Yu respectively.

Dalong, maybe both of them were injured during the fight."

The picture switches to Chen Chen's bedroom on the west side. "There is a small amount of wipe-like blood stains on the cabinets and drawers in this room. It belongs to Yu Dalong. It may be that his blood was on the handle when he was rummaging through his belongings after being injured in a fight with Chen Mo."

Waiting for a place.”

"The east wing is the same as the previous room, with only a small amount of wipe-like blood stains. At the scene, the blood stains of Chen Zhiping, Lu Chunyan and his wife were large, but the blood stains of Chen Mo and Yu Dalong were very small. I even felt that Chen Mo shed more blood than Yu Dalong.

The dragon is still young, so I speculate that Chen Mo’s death was caused by a heavy blow to the brain rather than excessive blood loss.”

"Chen Chen was found in the warehouse. Because she died of suffocation, there wasn't much blood, but the small amount of stained blood on her bedroom bed proved to be hers. It should have been the vaginal bleeding caused by violent assault."
