The formation of the task force this time was very rapid and the scale was very large.

Tianhua City is a big city with a population of 20 million, if it is said that in the jurisdiction of a certain police station, it is normal to not have a single homicide in a few years or even ten years, then looking at the whole city, there are always homicides every year, and it is not particularly rare.

But even so, the means of crushing corpses and sinking the river are still too bad, and it is easy to have a very bad social impact.

In order to crack down on the arrogance of criminals, the special task force dispatched by the city bureau is a trump card.

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

A large number of departments that are very good at their names are in this task force, in addition, the Municipal Criminal Science Research Center and two well-known universities in Tianhua City provide technical support.

Don't look at Bai Song and the instructor politely, but at this time, his blood is a little boiling!

I don't know if there is this kind of blood flowing in his bones, Bai Song's heartbeat has always maintained a high level.

The dormitory is an ordinary bunk bed, but with new sheets and quilts, it is very simple, and I went upstairs after cleaning up the white pine.

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

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

After about 20 minutes, all the comrades seconded from various units arrived, except for Sun Jie, who had been in the task force all along, and the other comrades were seconded together with Bai Song, adding up to almost 20 people.

Similar to Bai Song's expectations, Wang Huadong and Gao Chao were also assigned to the task force, and Gao Chao was also one of Bai Song's colleagues. In addition, Bai Song also saw a familiar face, it was not Wang Liang from the Sanlin Road Police Station, but Sheriff Li Han, who had met when he went there before, to deal with disputes.

Is there enough in this office to be willing to send the sheriff directly? Bai Song was surprised.

Soon, everyone arrived, and the political commissar of the criminal investigation detachment held a simple meeting for everyone, mainly talking about the progress of the case and the confidentiality regulations, and everyone also signed a confidentiality agreement.

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

The current progress of the case is mainly in three aspects.

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

The second is the cause of death, the deceased died from a blunt object forcibly hitting the back of the head, and the dismemberment of the body is not a means of death, but a means of hiding the body.

The third is that the source of the iron drum is already there, which is a chemical plant in Tianbei District, upstream of Tianhe River, Tianhua City, which is undergoing asset restructuring. The chemical plant had closed its doors last year, and all sorts of worthless items were piled up in warehouses or open spaces in the courtyard, attracting some red-eyed brokers.

According to preliminary analysis, the source of the iron drum has nothing to do with the owner of the chemical plant and others, but with the garbage recycling station outside.

After investigation, in Tianbei District, Tiandong District and Jiuhe District, there are more than a dozen waste collection stations where this kind of iron barrel has appeared.

In addition, there is a barely useful clue, that is, through chemical analysis and the report of the laboratory of Tianhua University, there is a fine gravel-like material with different properties from river sand between the pieces of the corpse, and it is currently inferred that the corpse was cut by a grinder.

The reason why this clue is useless is because for things like grinders, thousands of decoration, doors and windows can be found in Tianhua City.

The task of Bai Song and others is to collect the grinding wheel abrasives in the stores with grinding wheels in the city's carpet collection, each of which only needs to scrape a little bit from the grinding wheels, and finally summarize and take it to the laboratory for comparison, to finally confirm which brand of grinding wheel it is, and then further investigate.

This is an astronomical amount of work, and in addition to this kind of work, other members of the task force have made different attempts on different roads, and I have to say that in just three days, it is already very powerful to grasp so many clues from scratch.

In a group of two, the one who was separated from Bai Song was Li Han from the Sanlin Road Police Station.

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

"What kind of plan is this?" Li Han just got in the car, and complained: "I think that when we solved the case, we pushed it little by little according to the clues, but now it's better, looking for clues in a haystack." “

"Maybe it's true that there are too few clues. 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, in fact, the materials are similar, and this comparison must have been done before, but it is estimated that the comparison was not successful.

And almost all of the grinding wheels used are common grinding wheels.

Could it be that the people who install doors and windows do not use the ordinary grinding wheels sold in the hardware city on the cutting machine, and will also be specially customized and imported from foreign countries?

It is precisely because of this that Li Han complained about the significance of this work. But complaining is complaining, the work is still not ambiguous, after all, Sergeant Li is also a veteran policeman with seven or eight years of work experience.

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

"Yes, we are classmates, and we have known each other since college. Bai Song nodded: "Sergeant Li, the last time I went to the office, I saw you dealing with 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 then said: "Wang Liang, this kid is good, you good college graduates, the level is high." ”

Listening to Li Han's obviously somewhat praising words, Bai Songxin said that this is spending money to buy off Sheriff Li? How could he not know that Wang Liang had other advantages besides playing good games and loving to read some miscellaneous books?

"What's the matter, I don't have any level", Bai Song didn't answer, "What's wrong with Wang Liang, you can tell me." “

Bai Songzheng was curious, and chatted with Li Han for a few words before he knew what was going on.

Maybe the Sanlin Road Police Station is not as busy as the Jiuheqiao Police Station, so the candidates who are arranged to come to the task force are free to sign up. The opinion of the office is that if no one signs up, the assignment will be made.

Last night, the institute held a meeting for police officers under the age of 35 to talk about the situation.
