It happened 13 years ago, in a large supermarket in Jinshan District, Shanghai, a woman named Cao Bei came to work in the morning, Cao Bei's sister immediately contacted her sister, but her mobile phone was turned off. Cao Bei's sister immediately contacted her parents and asked her parents to go to Cao Bei's house to see, who expected Cao Bei and his wife to open the door of their daughter's bedroom, and actually saw their daughter lying on the bed covered in blood, and there was no breathing. At that time, she was the only one in the family, but she did not live alone, Cao Bei was already married, and she had a 6-year-old son. But the day of the incident was May 1st, and the school was closed. Cao Bei's husband took her son to the suburbs early in the morning, and Cao Bei did not follow because she had to go to work, and as a result, an accident occurred.
The police immediately launched an investigation, there were broken vases on the ground, and the reclining chairs were scattered around the body, indicating that the two had a fierce fight at that time. Cao Bei had multiple blunt blow wounds on her body, fatally in the neck. The police judged that it should be that some object had punctured the artery, causing heavy bleeding and causing death. The room has traces of being turned over, valuable electronic products such as mobile phones are missing, and the murderer entered the room through a climbing method, which looks like it should be a case of evil caused by theft.
Because the door locks of Cao Bei's house are intact, but the bathroom window sill has a square shoe print, and the room has signs of being cleaned. The police speculated that the murderer may have been a burglary, and then who knew that Cao Bei suddenly returned, the two collided, and the murderer suddenly moved his killing heart and took the murder weapon in the kitchen. But the police didn't think it was right, because the room didn't look like a theft, but rather disguised as a theft scene.
At this time, the police found water-stained shoe prints in the room, which are different from the shoe prints left on the bathroom window sill, are there two murderers? However, the police did not find any traces of shoe prints, which is unlikely, because the room is very small, and if there are two murderers, they will definitely intersect. At this time, the police found that Cao Bei's family lived on the 5th floor, and the building outside the washroom had a decorative eaves about 20 centimeters wide, which extended to the bottom of the corridor window on the 4th floor and a half. If the murderer had climbed in from the outside, he would have had to go through the kitchen fence, and as a result, several fingerprints were actually extracted from the fence on the outside of the kitchen.
The police found that next door to Cao Bei's house was an unoccupied rough room, and in the room the police also found the same fingerprints and square footprints. The police guessed that it should be a nearby resident, and good at climbing, and seemed to have monitored the Cao Bei family, so the police investigated the residents of the community, and a man named Zhu Weifeng attracted the attention of the police. He lived on the first floor, and Cao Bei's family lived on the fifth floor, but after the incident, he ran away from home for no reason. The police immediately tested his biological materials and fingerprints, and sure enough, they confronted Zhu Weifeng.
By December 2020, police had caught Zhu Weifeng, who had been absconding for years. Zhu Weifeng had a family at that time, his daughter was just 8 months old, why he killed people is too curious. Zhu Weifeng said that he and Cao Bei lived in a building that year, although the two did not know each other, but they often met in and out, and after a long time, Zhu Weifeng had different emotions for Cao Bei, which he called "love". He knew that Cao Bei had become a family, but he indulged his selfish desires and wandered in the fantasy, and often ran to peek at Cao Bei, and also sneaked to the next door of Cao Bei's house to peek.
After a long time, he was not satisfied with this, he wanted to get Cao Bei's QQ number, so on the day of the incident, he jumped into Cao Bei's home after the Cao Bei family left. He opened Cao Bei's computer, but because he could not solve the computer password, he could only give up, just when he was ready to leave, Cao Bei suddenly returned home, the two wrestled together, and then Zhu Weifeng harmed Cao Bei. Now he has no regrets, and all that awaits him is the punishment of the law.
