Police Detective

This time the task force was formed very quickly and its scale was very large.

Tianhua City is a big city with a population of 20 million. If within the jurisdiction of a certain police station, it is normal for there not to be a murder case for several years or even more than ten years, then looking at the city as a whole, murder cases always exist every year, and they are relatively normal. Not very few.

But even so, the method of dismembering the corpses and sinking them into the river is still too harsh, and it can easily have a very bad social impact.

In order to combat the arrogance of criminals, the task force dispatched by the city bureau is all ace.

Technical department, network, biochemistry, traces, current survey...

A lot of departments with awesome names are in this task force. In addition, the Municipal Criminal Science Research Center and two famous universities in Tianhua City provide technical support.

Although Bai Song was polite to the instructor, his blood was boiling at this moment!

I don't know if this kind of blood flows in his bones, but Bai Song's heartbeat has always been maintained at a high level.

The dormitory was just an ordinary bunk bed, but it had new sheets and quilts, so it was very simple. After packing Bai Song, I went upstairs.

The first floor of this building has been temporarily borrowed by the task force. Bai Song went to the conference room to report first.

Entering the conference room, there were not many people in the room, only five or six people. All kinds of materials were in order on the large conference table, and forensic doctor Sun Jie was also here.

About twenty minutes later, all the comrades seconded from each unit arrived. Except for Sun Jie, who had been on the task force, the other comrades were seconded together with Bai Song. In total, there were almost 20 people.

Similar to Bai Song's expectation, Wang Huadong and Gao Miao were also assigned to the task force. Gao Miao was also one of the colleagues assigned to Bai Song in the same term. In addition, Bai Song also saw a familiar face. The person who came from the Sanlin Road Police Station was not Wang Liang, but Chief Li Han, who he had met when he went there before to deal with disputes.

Is this place worthy enough? Just send the police chief out? Bai Song clicked his tongue in wonder.

Soon, everyone arrived, and Political Commissar Yu from the Criminal Investigation Detachment held a simple meeting for everyone, mainly talking about the progress of the case and confidentiality regulations. Everyone also signed a confidentiality agreement.

This confidentiality agreement is mainly for external confidentiality, confidentiality for non-members of the task force, and internal information sharing.

The current progress of the case mainly focuses on three aspects.

The first is the identity of the deceased. It has been learned that the deceased was a southerner. He died almost a month ago and was about 25 years old. Other than that, no other information is available. There was nothing on the deceased that could prove his identity, and no recent missing persons were found that could correspond to the deceased.

The second is the cause of death. The deceased was killed by forcibly hitting the back of the head with a blunt object. Dismemberment was not a method of death, but a method of hiding the body.

The third is that the source of the iron barrels is already available. It is a chemical factory in Tianbei District, upstream of the Tianhe River in Tianhua City, that is undergoing asset restructuring. This chemical factory had been closed down last year, and all kinds of worthless things were piled up in the warehouse or on the open space in the courtyard, which attracted some jealous brokers.

Preliminary analysis shows that the source of the iron barrel has nothing to do with the owner of the chemical plant and others, but has something to do with the garbage recycling station outside.

After investigation, it was found that such iron barrels had appeared in more than a dozen scrap collection stations in Tianbei District, Tiandong District and Jiuhe District.

In addition, there is another clue that is barely useful, that is, through chemical analysis and reports from the Tianhua University laboratory, there is a fine gravel-like substance between the pieces of the body that has different properties from river sand. It is currently deduced that this is The body was cut using a grinder.

The reason why this clue is useless is because there are thousands of decoration, door and window companies in Tianhua City that have grinders.

The task of Bai Song and others is to collect the grinding wheel abrasives from various stores with grinding machines across the city. Each one only needs to scrape a little bit off the grinding wheel. Finally, they will collect them and bring them to the laboratory for comparison to finally confirm. Which brand of grinding wheel is it? Then check further.

This is an astronomical amount of work, and in addition to this type of work, other members of the task force have made different attempts on different roads. It must be said that in just three days, they have mastered so many clues from scratch. It is already very powerful.

In a group of two, the person assigned to Bai Song was Li Han from the Sanlin Road Police Station.

According to regulations, the two people changed into casual clothes, drove into a car with a local license plate, and went out. The place they went to was 20 kilometers away from here, in Tiandong District.

"What kind of plan is this?" Li Han complained as soon as he got into the car: "Back then, when we solved the case, we always relied on clues to solve the case, but now it's better to find clues from the haystack."

"Maybe there are indeed too few clues." After listening to Li Han's complaints, Bai Song didn't know how to answer, so he said vaguely. To be honest, although there are many styles of grinding wheels, the materials are actually very similar. This kind of comparison must have been done before, but I guess it was not successful.

And almost all grinding wheels used are common grinding wheels.

Is it possible that people who install doors and windows don’t use the ordinary grinding wheels sold in hardware stores on their cutting machines, but also customize and import them from foreign countries?

It is precisely because of this that Li Han complained about the significance of this work. But complaints are complaints, and the work is still unambiguous. After all, Chief Li is an experienced policeman with seven or eight years of work experience.

"By the way, you and our new kid Wang Liang graduated from the same school, right?" Li Han started chatting while driving.

"Yes, we are classmates and have known each other since college." Bai Song nodded: "Sergeant Li, last time I went to the station, I saw you handling that dispute, it was really amazing."

"Hey, that's not my credit, it's all the camera's credit." Li Han shook his head and continued: "Wang Liang is a good guy. You guys who graduated from good universities are of high standard."

Listening to Li Han's obviously complimentary words, Bai Song thought to himself that he had spent money to bribe Chief Li? Why doesn't he know that Wang Liang is good at playing games and loves to read some miscellaneous books, what other advantages does he have?

"No way, I'm not very good at it." Bai Song didn't answer the question, "By the way, what happened to Wang Liang, please tell me."

Bai Songzheng was curious, and he chatted with Li Han for a while before he found out what was going on.

Perhaps the Sanlin Road Police Station is not as busy as the Jiuheqiao Police Station, so the candidates assigned to the task force are free to sign up. The opinion of the office is that if no one signs up, they will be assigned.

Last night, the station held a meeting with police officers under the age of 35 to discuss this situation.
