On August 2016, 8, the Yanjing Police Station received a report and found a dead body in a building under renovation.Zhao Lei, deputy captain of the criminal police team of the police station, led the police to the scene of the crime. The scene of the crime was on the sixth floor of a construction site under renovation.

"The deceased was a middle-aged male with a medium build. His right wrist was cut open, and there was a blood-stained glass fragment next to it. There was a lot of blood. There were no obvious signs of fighting at the scene. The cause of death of the deceased was that the artery in the right wrist was cut open. Bleeding to death, a bottle of sleeping pills was found next to the deceased, whether the deceased took sleeping pills before death, further autopsy and testing are needed.” After investigation, the forensic doctor made a preliminary judgment.

A young decoration worker was the first to discover the body and called the police. It is understood that the reporter was the decoration staff here, responsible for the ground decoration of this floor.Because the room is not well decorated, the doors are all open, but the door of this room is locked. This kind of door can be locked from the inside without a key. You just need to pull the spring and close the door to lock it. The informant He opened the door with the spare key, and was so frightened when he found the deceased that he called the police tremblingly.

After on-site investigation, the door of this room is intact, there is no sign of violent opening, all windows are closed, and it is located on the sixth floor.This building is still being renovated and is not open to the public. Except for the decoration workers and the person in charge of the construction site, few people come here.

Zhao Lei stood in front of the window, observed it, opened the window and looked out carefully, and asked Xiao Liu, who had been a police officer for half a year, "What do you think?" Xiao Liu had already checked the information of the deceased, observed the scene for a while, and then looked The deceased, after a little thought, replied, "The deceased is a relatively well-known private entrepreneur in this city. He used to have a rich family, but later because the company's funds were broken, he filed for bankruptcy at the beginning of this month. The RV was mortgaged and he owed a lot of debts. The death time of the deceased should not exceed [-] hours, and he was still in the period of plaque accumulation. Looking at the mobile phone of the deceased found at the scene, he sent a WeChat message to his wife six hours ago. After going bankrupt, he had nowhere to go and took short-sightedness." Zhao Lei shook his head and said, "This should be a murder case in a secret room. Although the deceased had a plausible reason for suicide, if you observe carefully, you can find that the deceased is right-handed, with a left wrist. Although the body does not wear a watch, there are traces of wearing a watch for a long time. If a right-handed person commits suicide by cutting his wrist, generally speaking, he will use his right hand to cut the artery of the left wrist. Look at the corner of this room, there is a sharp For ordinary people, even if it is suicide, they will choose a relatively gentle method. Cutting an artery with a wallpaper knife is far more acceptable than cutting an artery with this rough glass ballast. Okay, first Speaking of this, don’t look at the surface in everything. In our business, you have to have sharp eyes and a careful heart. Do you still remember the case I told you that day, and you will experience it when you go back.”

After surveying the scene, Zhao Lei took out a piece of paper and wrote: Glass shards, sleeping pills, right wrist.This is a habit that Zhao Lei developed a long time ago. Every time he encounters a case, he always writes a few key words and thinks about it slowly when he goes back.
