Record of the Case of the Dismembered Corpses of Three Beautiful Sisters: The murderer was right next to the victim and escaped scrutiny every time. What happened next?

Mom and Dad, stop asking me if I have a girlfriend. This made me feel invisible pressure. I suddenly wanted to drink and be a bad boy. When I was drunk, I could cry aggrievedly. Alan Xincheng. This is the diary written by Lan Xincheng before committing the crime. It was also a silent vent for a mentally fragile person. In Lan Xincheng's view, parents' concern is invisible pressure. He knew his parents loved him, but he was too incompetent to satisfy them. Lan Xincheng did not change his pressure on power, but distorted his psychology and vented his personal desires through killing the body. This "devil" hidden around us finally started to attack the "three sisters".

The Qin couple are from Nanning and have raised four daughters. Seeing that their daughters have grown up, the old couple should also enjoy a happy life. In February 2009, Amy Tan and his wife went to Guangzhou to visit their eldest daughter. According to the plan, the three and four sisters will pick up the new couple and return to Nanning on February 11. Father Qin waited for a long time without seeing his daughter, and no one answered the phone. The eldest daughter comforted her and said: Maybe something has delayed her, don't worry. In order to contact the third sister as soon as possible, the fourth sister quickly called the second sister, but no one answered. The second sister opened a store and called the store girl next to her. She was told that the second sister was not open for business.

So the eldest sister is very worried. It would make sense if the third and fourth sisters were having so much fun that they forgot to pick someone up. But the second sister has always been self-disciplined. Business is very important. How can she not open the door for no reason? An ominous premonition arises spontaneously! The next day, the eldest sister came to Nanning with her parents and found the three sisters' residence, but found that the motorcycle was still in the room downstairs. She felt a little relaxed.

They went upstairs, opened the door, and saw that the house was empty. The three sisters are not at home. No one has moved in the room, even the quilt has been folded. The three sisters went on a trip, so why not turn on their mobile phones? Anything else? Anyway, the three sisters disappeared. After the Qin family called the police, the police came to the scene to check and found nothing abnormal. In order to find the three sisters as soon as possible, the Qin family published missing persons notices on major media in Nanning. Meanwhile, investigators intensified their search. But day after day passed, and there was still no news about the three beautiful sisters. On February 16, 2009, there was a breakthrough.

Two migrant women said they smelled a foul odor at a construction site in the back hills of a residential area in Nanning, caused by two bags of rotting meat that looked like human body parts. Investigators arrived at the scene and found two woven bags containing body parts. Nine more bags of body parts were found nearby. Forensic scientists pieced together three female victims. Investigators compared the mutilated body with the information of the three Tan Si sisters and found that it was these three people.

Three beautiful sisters were murdered together, and their bodies were brutally dismembered by the murderer. This case caused a great sensation in Nanning, and the investigators were under great pressure to solve the case. Since there were no signs of a fight in the sisters' room and no money was missing, investigators concluded that an acquaintance may have committed the crime. Due to the extensive communication between the three sisters, the police invested a lot of police force and searched all the people related to the three sisters, including friends, neighbors, relatives, colleagues, etc., and arrested more than 3,900 people, but the murderer was never found.

The case of the mutilated bodies of three sisters is mired in a mystery that has investigators under tremendous pressure. After 68 days of hard work, they finally had a breakthrough. The special service team believes that the neighbor of the three sisters, Lan Xincheng, is a major criminal suspect. Lan Xincheng was interrogated eight times without any problems, all because of the emergence of some new evidence. After repeated investigations, investigators discovered that Lan Xincheng had studied at a vocational college and graduated in 2004. The school quilt bag was the same bag used to hold the body parts. In addition, Lan Xincheng works in a cabinet store. He arrived at the store just before noon on February 11. According to the owner, Lan Xincheng is usually not late. After get off work that day, Lan Xincheng took another three days off. His whereabouts coincided with the murder of the three sisters, and he was the main suspect in this case.
