Zhang Zhan went home after dawn, took a shower and slept for a while, and then started his ordinary ordinary life. Exercise every day and go to the boxing club to practice, and occasionally go on a date with Wang Huili to solve the problems that need to be solved by each other.

As for the black skin, he didn't care anymore. Although he knew that the body would be found sooner or later, the police would also launch an investigation. However, he did not think that the police would suspect him, and even if they did, they would not be able to find any clues and evidence.

And the black skin is indeed sad enough, there is no one in this world who cares about him at all. Although he was still approached by people after his death, such as the maître d'art of the ballroom and a few fox friends who often gambled together. But after no one answered his call, he didn't care about him.

It wasn't until a few days later that the corpse began to rot and stink, and the residents living in the dilapidated building didn't feel that something was wrong. But it was still two days later, and the smell of the corpse had already smoked, so the police began to break down the door and finally found the scene of the murder.

Li Nan is a member of the serious crime team of the Criminal Investigation Brigade of the Municipal Public Security Bureau, and when she received a call about a murder on Miaowang Street, she was investigating a counterfeit banknote case with Jiang Yunye, the head of the criminal investigation team. However, due to the lack of clues, progress has been slow.

Hearing that there was a homicide on Miaowang Street, Jiang Yunye immediately suspended the investigation of the counterfeit money case and drove to the scene of the murder with Li Nan.

Jiang Yunye is 34 years old, known as the elite of the police circle, and he has solved countless major and important cases, and he is a good case solver admired by everyone in the Gaohe City Police Department. After driving to Miaowang Street, the murder scene has been cordoned off. He and Li Nan got out of the car and walked into the dilapidated small building, came to the crime room on the third floor, and saw that colleagues from the police station were examining the body, searching the room, and taking pictures of the scene.

A strong smell of corpses made Li Nan can't help but cover his nose, but Jiang Yunye looked calm and didn't seem to feel anything. He took out the white gloves he had brought with him, put them on his hands, and walked into the room. When the colleagues inside saw him come in, they all nodded and greeted, "Team Jiang, you're here." ”

Jiang Yunye walked to the body of the black skin, looked at it carefully, and asked a policeman who came over, "Xiao Guo, what is the situation of the deceased?" ”

The policeman said: "Team Jiang, the deceased's name is Zhao Yong, nicknamed Heipi, and he is a well-known gangster in the Miaowang Street area. The medical examiner just examined and found that the deceased was killed by him, and his throat was cut with a sharp weapon. The time of death has been about five or six days. ”

Jiang Yunye nodded, and asked again, "What did you find at the scene?" ”

The policeman said: "Hardly, the murderer is very sophisticated, and he has not left any obvious clues." Now they are looking for a place where the killer may have left fingerprints and footprints, and two police officers are questioning the residents upstairs and downstairs to see what clues can be found. ”

As he spoke, two forensic doctors had already arrived to remove the body. Jiang Yunye turned back to Li Nan and said, "Xiao Nan, I'll stay at the scene, you go and check who you have had close contact with the deceased before his death." Find out what the deceased has done and who he has offended in the recent period. ”

Li Nan hurriedly said, turned around and left.

A day later, at an internal case meeting of the Municipal Public Security Bureau, Li Nan reported on her investigation of the deceased's pre-existing situation, saying: "The deceased worked as a security guard at the Hongluo Song and Dance Hall on Miaowang Street, and his working hours were generally between 7 and 12 o'clock in the evening. According to interviews with the dance hall staff, the deceased was quite dedicated to his work, and rarely arrived late and left early. But this person has a short temper and does not have a good relationship with most of his colleagues. Moreover, the deceased was an alcoholic gambler and owed many debts. In addition, the deceased had a very serious tendency to violence. During his tenure as a security guard at the dance hall, he injured the guests of the dance hall several times and had violent clashes with the staff of the dance hall. ”

Speaking of this, Li Nan paused and said: "Through investigation, I found a few people who had a lot of contacts with the deceased before his death, basically all of them were gangsters in the area of Miaowang Street, and they were also gamblers who often gambled together. According to these people's confessions, the deceased was usually brave and ruthless, and often fought when he disagreed. The number of people he has offended is almost impossible to count. In addition, there is another important situation, according to one of the gamblers, the deceased is too famous for fighting, and people often hire him to be a thug, do some beating, debt collection, smashing the field and other illegal acts. The deceased made some extra money as a result, and made countless enemies as a result. ”

Speaking of which, Li Nan said that the report was over, and that was all for the current investigation. The leader in charge of criminal investigation of the city bureau present nodded and said: "Very good, it seems that there are many people who have offended this deceased black skin, which has brought certain difficulties to our investigation work." However, just now Captain Jiang has already briefed on the investigation of the scene, and the case has been determined to be a vendetta. Because nothing was lost in the deceased's room, and he did not have any contact with women during his lifetime, this ruled out the possibility of robbery and love killing. Revenge homicide is the main direction of our investigation in solving this case. So this line, we must follow up. The people who have bullied the deceased before and those who have offended must be investigated clearly. Then check one by one until you lock down the suspect! ”

The leader gave an order, and the people of the criminal investigation team began to get busy. A day later, an important clue surfaced. According to the memories of people in several Internet cafes and billiard rooms in the Miaowang Street area, two days before Heipi's death, a middle-aged man with sunglasses and a beard on his face had asked about Heipi everywhere.

There was monitoring equipment in the Internet café, and when I called it up, no one knew this person. But there is no doubt that this person is suspected of a major crime. So the people in the police station mobilized everywhere to find out who this middle-aged man was. I hurried for several days, but I found nothing. This middle-aged man with a full beard has no origin or record. It seems to have appeared out of nowhere, and then vanished out of thin air. No one knew what his last name was, where he came from, and where he went.

Li Nan and a few police officers were responsible for investigating the sins of the deceased Heipi before his death, and after being busy for a few days, he gained a little. According to the results of the investigation, there are more than 20 people who have had conflicts with Heipi, or who have been injured, blackmailed, or bullied by Heipi.

At night, when the police station was summarizing statistics, Li Nan suddenly saw the name of one of them, and suddenly laughed and said, "Why is he again?" How hateful should this poor Teacher Zhang be, even the black skin has taught him a lesson? ”

PS: Well, after all, I'm not a policeman, and I don't know how the specific case was investigated and solved. What is written in the book is completely my imagination, you don't have to take it seriously after reading it, just laugh and pass.
