Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 422 Northern Street Old Street
A huge investigation work was launched accordingly.

Although the case was taken over by the Provincial Serious Crime Team, it actually happened in Tianzhou City, and the Public Security Bureau here is shouldering the responsibility. This huge investigation work must be based on the strength of the Tianzhou City Public Security Bureau.

Before starting, Li Donglin was doing a mobilization meeting.

"Although the main investigation force is the Tianzhou City Public Security Bureau, you are actually responsible."

"Judging from the current situation, the murderer should have lived on Nanshan Road in the early years, and later moved to Beifang Street. This investigation will focus on Beifang Street. We must ensure 100% investigation without any omissions. We pay special attention to the move from Nanshan Road to Beifang Street. of."

Wang Song, Song Mingguang and others are all veterans in this field. They don't need Li Donglin to explain whether the investigation is successful or not, which may determine whether the case can be solved.

As for the 100% investigation required by Li Donglin, it is not difficult to achieve this.

Based on the local police station and neighborhood committee, it is actually not difficult to concentrate efforts on the residents of a street to find out the residents.

Needless to say residents, everyone in the neighborhood will be familiar with it, and the floating population is actually easier to investigate.

Whether the floating population rents a house or works on Beifang Street, they must have a landlord or boss.

It's easy to find if you have roots.

Especially considering that the time span of the crime exceeds 10 years, it is unlikely that the other party is a floating population.

Not only cannot it be a floating population, but the other party must also have a relatively stable place to dispose of the corpses.

It is necessary to have tools for dismembering corpses so that they are not easily discovered.

Renting an apartment to do this kind of thing... is unlikely.

The difficulty lies in the accuracy of the investigation.

Last year, a bizarre murder occurred in Hangzhou. My wife disappeared in the middle of the night and her body was nowhere to be found.

When a wife goes missing, her husband is naturally the first suspect. However, after several rounds of investigations and interviews, the wife’s husband has never revealed any clues.

Later, even if the local police had clues, they could not find the body of the deceased, so they could not confirm that it was the husband who killed him.

It wasn't until the police salvaged the domestic sewage transfer septic tank in the community for several days and nights, and got some dregs and debris, which were analyzed and determined to be human tissue. Combined with the surge in water consumption at the deceased's home that night after the wife's incident, they finally located it. The husband was suspected of committing the crime.

It can be seen from this case that the investigation of the suspect does not mean that once the person is found, the other person will be found to be the murderer.

No one will have the word "murderer" carved on their forehead.

The most difficult part of the investigation is finding suspicious clues.

"In addition... pay attention to safety. The other party has killed so many people. It can be said that they are extremely vicious. No one knows whether they have lethal weapons. We must be more vigilant. No one can act alone."

Li Donglin has experienced something like this. Five years ago, he was involved in a vicious case supervised by the ministry.

Due to a shortage of manpower, the local police officers involved in the investigation were divided into teams of at least two people.

One of the police officers discovered the suspect during the investigation. The police at the time were not eager for quick success and did not take action directly, thinking of going back to bring in reinforcements.

As a result, the other party seemed to know that he had been exposed. When the police turned around and left, he attacked from behind and hit the police officer on the neck with a kitchen knife.

The two investigated, this is a lesson brought by blood and life.

"Don't worry, Li Chu, several of us have been through it before, and we will never make such a low-level mistake."

Not to mention Wang Song and others, even Lu Chuan, who is the youngest and has the least experience in field work, would not do this now.Don't have impulsive heroic ideas unless necessary, as this will not only harm yourself but also harm others.

Of course, there are no absolutes in the world, and of course you have to save your life if it is not necessary. But sometimes when you put on the uniform of a police officer, you can't just take a step back if you want.

When we meet on a narrow road, the brave wins. Many times it’s one-on-one. If you don’t win, no one will.

Sun Jianguo, a veteran policeman dispatched by Renmin Road in Tianzhou City, is 59 years old this year. Sun Jianguo will retire in one month and three days.

North Street is under the management of Renmin Road Police Station.

"Old Sun, don't go on this mission. You will retire in a month. Just do some internal work and don't go out in the field."

It is an unwritten tradition at the Renmin Road Police Station of the Tianzhou City Public Security Bureau that all veteran police officers who are less than three months away from retirement are not assigned to field missions.

"Chen Suo, I know you are taking care of me, but isn't it because the institute is busy? The number of people can't be divided. It's not a big problem to participate in such a big case. Anyway, it's just a investigation."

Chen Jiang was slightly silent. The rules in the institute were not made by him, but were left by the previous director.

As for why...

The lessons left by human life.

Fifteen years ago, there were two veteran policemen in the Renmin Road Police Station. One had two and a half months left before retirement, and the other had ten days left.

There was also a case that needed to be investigated at that time. The two went to investigate as a team, but the suspect directly detonated the boiler room and no one came out.

The two policemen at that time had been at the Renmin Road Police Station since its establishment. It can be said that they built the Renmin Road Police Station.

Basically all the young people in the institute were brought out by them.

Therefore, the then director of Renmin Road Police Station left such an unwritten rule in memory of the two of them.

Sun Jianguo obviously saw Chen Jiang's hesitation. He was one of the many apprentices when this happened.

"Okay, okay, I won't cause any trouble to you, Laojie. Erhe and I will go to Laojie."

Upon hearing Sun Jianguo's request to go to Old Street, Chen Jiang's expression softened.

Renmin Road Old Street is actually a small alley. It was the prototype of Renmin Road in the early years. The entire Renmin Road was actually developed around the old street. North Street is one of the main streets.

Since the infrastructure is average, the people living there are all old residents of Renmin Road. There are only about thirty households in total, and everyone in the house knows everyone.

Sun Jianguo moved out of the old street back then, and no one was more familiar with the people there than he was.

Erhe's full name is Zhang Erhe. He was Sun Jianguo's former neighbor. He was tall and powerful. Now he is an auxiliary policeman. He used to like Sanda. He was considered a martial arts practitioner and was the leader of the department's combat effectiveness.

As long as he's here and it's the old street, everything will be fine!
"Third uncle, do you still need it over at the old street?"

In fact, there is no seniority when working in the institute. The older ones are called brother or sister.

Only the relationship between Zhang Erhe and Sun Jianguo is different. Zhang Erhe's father and Sun Jianguo grew up naked, and Sun Jianguo can be said to have watched Zhang Erhe grow up.

Later, Zhang Erhe joined the station as an auxiliary police officer, and it was Sun Jianguo who recommended him.

This is not a secret. Everyone in the institute knows that Zhang Erhe calls Sun Jianguo Third Uncle.
