This morning, the city received a call from the police who said that his employer had been killed in his home. After investigation, the identity of the deceased was Chen, deputy editor-in-chief of Lantong Evening News. The forensic doctor preliminarily judged that the deceased died of excessive blood loss due to a ruptured pulmonary artery, and the time of death was between 18:30 and 19:30 last night. Jiang Chen and I arrived at the scene of the crime, and Xiao Zhao told us that the informant's name was Li Sha, who was the nanny in the victim's home. I immediately began to question the informant.

I asked, "Hello, when did you find the deceased?" ”

Lisa said: "At 7 o'clock, I come here every day at this o'clock to clean. ”

I continued to ask, "Can you carefully recall the scene when the deceased was found?" ”

She said: "I came to Mr. Chen's house at 7 o'clock this morning as usual to clean up. But as soon as I opened the door, I saw Mr. Chen lying on the ground covered in blood and a knife stuck in his body. So he immediately called the police. ”

Li Sha was obviously frightened and couldn't ask for more useful clues, the deceased died in the house, the body was near the door of his house, the murder weapon was a fruit knife, when the police arrived, the knife was inserted in the deceased's chest, the door of the deceased's house showed no signs of violent lockpicking, but there were traces of human beating or vandalism on the outside of the door. There are no traces of rummaging in the home and no valuables have been lost. There were traces of vandalism or blows on the outside of the gate, but there were no signs of being broken, so the murderer did not break into the door by violent means. The fact that the money and property at the scene were not lost indicates that the murderer did not commit a burglary. The scene was not locked, and although there were traces of damage, the door was far from being broken, indicating that it was likely that the deceased had opened the door for the murderer.

I asked Jiang Chen: "Is there a result of the fingerprint identification on the spot?" ”

Jiang Chen said: "No fingerprints were found on the murder weapon, and the fingerprints of Li Sha and a person named Liu Xu were found on the outer doorknob of the deceased's house. ”

After a preliminary investigation, Liu Xu once opened a steamed bun shop, but went bankrupt after being exposed due to unhygienic ingredients, and this person is still under investigation. The deceased's mobile phone was also found at the scene, and the deceased had three call records on the night of the crime, and the two unconnected calls were made by Liu Xu. There is also a call from a person who notes Li Mingyang, and the call is 2 minutes long. At present, I only know that Li Mingyang is a friend of the deceased, and the specific information investigation department is visiting and investigating, and Jiang Chen and I plan to investigate this Liu Xu first. Jiang Chen immediately sent someone to detain Liu Xu, and on the way back to the police station, a background investigation report was sent to Jiang Chen's mobile phone: Liu Xu, male, 32 years old, the former owner of the chain of Baobao shops, caused the chain of Baobao to go bankrupt because it was revealed that the meat filling used in the buns was dead rat meat. After bankruptcy, he was in debt due to the rent of the store and the salary of employees, and after investigation, the person who exposed his store was Chen Tong, deputy editor-in-chief of Lantong Night News. Rushed to the police station, Liu Xu was already in the interrogation room, and Jiang Chen and I began the interrogation.

Jiang Chen: "What were you doing at Chen Tong's house last night?" ”

Liu Xu: "I asked him for an explanation, and he framed me." ”

Me: "Tell me more about it. ”

Liu Xu: "I used to run a chain of steamed bun shops, which was originally good, but suddenly one day an article framed my steamed buns for being made of dead rat meat. In those days, I happened to run into several other chain stores where the kitchen hygiene inspection was not up to standard. The overwhelming public opinion followed, and I had to close down the bun shop in succession, but the remaining shops gradually couldn't make ends meet, and finally the capital chain broke and I could only declare bankruptcy. I've been saddled with a lot of debt because of this, but I'm really not using carrion, I'm being framed. ”

Me: "How do you know that Chen Tong framed you?" ”

Liu Xu: "I didn't know, but last night an unfamiliar number sent me a short message, telling me that Chen Tong was the ghost, and attached relevant documents and Chen Tong's information to corroborate, I was very angry when I saw this, and I went to Chen Tong's house overnight to ask for an explanation." ”

Jiang Chen: "What time did you go?" ”

Liu Xu: "I arrived around 19:40." I kept knocking on the door after I arrived, but no one answered, and I don't know if he wasn't at home or if he was deliberately avoiding me. I was so angry that I kicked the door a few times and went back. ”

After interrogating Liu Xu, I asked Jiang Chen to verify the truth of the confession. It didn't take long for a conclusion to be reached. On the night of the incident, there was indeed a resident in the vicinity of the deceased's house who had seen Liu Xu. According to his confession, at around 19:40 last night, the resident heard that someone had been knocking on the door, which lasted for more than 10 minutes, which was really disturbing the people, so the resident went out to persuade the knocker to leave. We provided the resident with a photograph of Liu Xu and confirmed that he was the one who knocked on the door. The time of death of the deceased was 18:30-19:30, and it was already around 19:40 when Liu Xu arrived at the scene of the crime, and the deceased should have died at this time.

Jiang Chen: "Can Liu Xu rule out suspicion?" ”

Me: "It's too early to draw this conclusion, Liu Xu don't let it go yet." Now let's let the technical department investigate who is the owner of this last number? ”

After tracking the unknown number, we found that this number was a virtual number constructed by a network IP, and according to the IP address query, we found the producer of this virtual number - Wenk. Wenk was a colleague of the deceased and now co-editor-in-chief with the deceased of the Lantong Night. Jiang Chen immediately sent police officers to Wen Ke's house to interrogate and investigate him. Soon after, we arrived at Wink's house. At this time, the Investigation Bureau had already found some clues related to the suspected case at Wenke's house. A document bag was filled with information related to Chen Tong, mostly negative information about Chen Tong's life and work, as well as a small packet of castor seeds.

Another chat history between him and Chen Tong was found in Wenke's mobile phone:

Chen Tong: How did you think about what you told you before?

Wink: I can't give you a chance, you're going to die.

Chen Tong: I know you have my handle in your hands, but you have to think clearly, what I do will be expelled at most, and the thing you do will be imprisoned.

Wink: Give me more time and I'll get back to you at dinner next week.

The handle in Wen Ke's hand seems to be Chen Tong's rumor about Liu Xu, what did this Wen Ke do to make Chen Tong so threatening.

Me: "Are you done now?" ”

Jiang Chen: "The trial is over, and the interrogation transcript has just been sent." ”

The transcript reads as follows:

Police: Why did you send those messages to Liu Xu?

Wen Ke: Chen Tong and I are competitors, and only one of us can be selected for the editor-in-chief election this time, so I thought about leaking Chen Tong's scandal to Liu Xu and asking him to expose Chen Tong, who would have thought that he would kill Chen Tong.

Police: Where were you on the night of the crime?

Wink: I was out drinking last night, you can get the hotel staff and my friends who can testify for me.

Police: What did Chen Tong threaten you about?

Wink: This is my personal matter and has nothing to do with the case, and I have the right to remain silent.

After reading the transcript, Jiang Chen and I immediately interviewed Wenke's friends and hotel staff, and the testimony of the people, coupled with the hotel's surveillance, confirmed that Wenke had indeed stayed at the hotel on the night of the crime.

Jiang Chen: "It seems that it was indeed not Wen Ke who killed Chen Tong. However, if this does not happen, I am afraid that Wink will really become a murderer. ”

Me: "Wink is also a smart man, and he plans very well, but unfortunately he is clever in the wrong place. ”
