At four o'clock in the afternoon, everyone gathered in the criminal police team office.
According to usual practice, Qin Youwei showed the autopsy report first.
The deceased Wang Xu, 22 years old, was from Geyuan City, Dongtai Province. He had just graduated from Meihai University and worked at Mero Financial Company in Xiacheng District.
The time of death was around 1 o'clock in the morning on June 22, which was the early morning of yesterday. The cause of death was mechanical asphyxia. There were strangle marks on the deceased's neck, but they were not very obvious. Qin Youwei judged that the murderer was strangled to death through a layer of towels or sheets.
The deceased was violently assaulted before his death, with multiple lacerations on his lower body and friction injuries caused by hard metal objects.
Qin Youwei extracted the male's body fluid from the deceased's body. The DNA of the body fluid completely matched the DNA of the hair found on the deceased's bed. There was only the biological information of the deceased and the male in the deceased's room.
After autopsy, Qin Youwei found residues of ether drugs in the respiratory tract and gastric juice of the deceased. It can be seen that the murderer first stunned the deceased with the drug, and then tied the deceased and tortured him.
Chen Xiaoxiao visited Wang Xu's neighbors. The neighbor downstairs was not at home last night, and the neighbors on the same floor found nothing.
There were no signs of being pried open on the door lock, and how the murderer entered the deceased's room became the focus of discussion.
"The murderer and the deceased knew each other, and the deceased opened the door on his own initiative. After entering the door, the murderer suddenly made a move and stunned the deceased. After that, the deceased was kept under control, so he did not make any abnormal sounds." Fu Xingliang analyzed.
Sun Xiaokai said, "I checked Wang Xu's call records and social software records, and no one contacted Wang Xu in advance and said they wanted to come to her home."
"Doesn't this rule out the possibility of takeout or express delivery?" Fu Xingliang said, "This acquaintance suddenly appeared outside her door. It was going to rain heavily. She would at least open the door and give out an umbrella."
Lu Wan did not rush to a conclusion. She asked Peng Yuetao, "How was the social relationship of the deceased?"
Peng Yuetao said: "In addition to going to work and partying with some college classmates, I have no boyfriend or friends with whom I have conflicts. Social relations are very simple."
Lu Wan looked at Zeng Hao and Bai Mo again. She noticed that after the discussion began, most of Bai Mo's attention was on the small drawing board in his hand. It seemed that Bai Mo had discovered something.
"We did find something here." Zeng Hao told him and Bai Mo about their investigation. They had already completed the portrait of the customer.
The man in the raincoat turned around and went downstairs after seeing the guest. His action was very problematic. He obviously didn't want people to see his face. Even if he was not the murderer, he must have done other bad things in the building.
Many people were overjoyed, but Lu Wan said: "What problem did you encounter?"
"Well!" Bai Mo put the drawing board up, "The light in the corridor where the two met was broken. The other party was still wearing a raincoat and a rain hat with a low brim. He could hardly see the other party's face."
On the drawing board was a sketch of a man wearing a split raincoat, with one hand pressing the brim of the hat, his head slightly lowered, and the exposed face was dark. Bai Mo only outlined the outline of his chin and ears.
"I have tried my best to draw what the guest saw, and he also confirmed that this is what he saw at that time." Bai Mo said, "I also confirmed that the other person was about 1.8 meters tall and was on the thin side. But I think..."
"The murderer's raincoat can be considered a breakthrough." Lu Wan interrupted Bai Mo. She knew that Bai Mo was preparing to reason about the case.
Bai Mo's way of reasoning about the case was to pretend that he was the murderer. Lu Wan was worried that this would affect Bai Mo's condition, so he deprived him of the opportunity to express his opinion.
Lu Wan continued: "It is a split raincoat, and it is a well-fitting split raincoat. It can be seen that the murderer did not take the raincoat from the deceased's house. He had premeditated it. It had not rained when he came to commit the crime. Bringing a raincoat shows that he The plan was to leave in the rain after committing the crime.
Since it was premeditated, the murderer must have investigated the deceased in advance, made a plan, and then chose to commit the crime on a rainy night... "
When Lu Wan said the word "rainy night", she paused.
Many murders occur on rainy nights. As we all know, weather can affect people's mood. Bad weather can affect people's mood and lead to extreme behavior.
Rainy nights are also natural havens for crimes. Thunder can cover up the sounds of crimes, and heavy rain can wash away traces of crimes.
Lu Wan was thinking that the murderer chose a rainy night to commit the crime, whether it was because the rainy night stimulated his psychology, or because the murderer felt that the rainy night could cover up the traces, at least it showed that the murderer did not resist the rainy night.
Three days later, Meihai City will usher in a second round of heavy rain.
More than half of the people present were awakened by the word "rainy night", and they also thought that there would be a heavy rain in three days.
Bai Mo once again held the drawing board and fell into deep thought. He didn't care that Lu Wan interrupted him. At this moment, he just wanted to catch the murderer quickly and let the woman in white rest in peace.
The woman in white?
Bai Mo frowned: Why should I call her the woman in white? Logically speaking, I should call her the deceased and the victim. Is the white coat a label used by the murderer to choose his target?
When the word label was mentioned in a murder case, it meant a serial murder case. Bai Mo was suddenly surprised. Why did he think this was a serial murder case?
While thinking, Bai Mo took out his mobile phone, opened an online shopping APP, searched for a white summer shawl, and soon found the white gauze dress worn by the deceased.
It's the end of June, and it's already a hot day. This kind of white gauze clothing can be used as sun protection clothing. There are many similar styles on the street. From this point of view, the white clothing does not seem to be the label that the murderer chose her for.
Lu Wan noticed that Bai Mo was already in a daze. She cleared her throat. Everyone looked at her, but Bai Mo was still in a daze.
Lu Wan began to assign tasks: "Old Qin, list the ingredients of the drug. Zeng Hao and Peng Yuetao are responsible for investigating the source of the drug. Xiaokai, try to check the sales of the same split raincoat in Meihai City. If the quantity If it's too big, just give up.
Fu Xingliang sorted out all the residents in Wang Xu's old building and listed all the men living alone who fit the criteria of Bai Mo's portrait. I don't think it can be ruled out that the residents in the building committed crimes.
Leave the situation at Wang Xu's company to me. I can just go there and visit it myself. The probability of gaining anything is very low. "
After speaking, Lu Wan looked at Chen Xiaoxiao, "Just cooperate with Bai Mo and see if there is any other way to make the portrait clearer."
Lu Wan's words had another meaning. She asked Chen Xiaoxiao to keep an eye on Bai Mo.
Bai Mo is a living person. Lu Wan can only stop him from speaking, but he can't stop him from investigating the case.
Simply let Chen Xiaoxiao follow Bai Mo and see if Bai Mo can find clues that others can't detect by pretending to be the murderer. With Chen Xiaoxiao here, he is not afraid of Bai Mo's accident.
