Police Detective

　　 The formation of the task force is very rapid this time, and the scale is also very large.

Tianhua City is a big city with a population of 20 million. If it is normal for a police station to have no murders in a few years or even more than ten years, then looking at the whole city, there are always homicides every year. Not very small.

　　 But even so, the methods used to break the corpse and sink the river are still too bad, and it is easy to have a very bad social impact.

　　 In order to combat the arrogance of criminals, the task force drawn by the city bureau is a trump card.

　　Technology department, network, biochemistry, trace, site survey...

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

　　 Don’t look at Bai Song and the instructor being polite, but at this time his blood is boiling!

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

　　 The dormitories are ordinary upper and lower bunks, but with new sheets and quilts, it is very simple. After finishing the white pine, I went upstairs.

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

　　 entered the conference room. There were not many people in the room. There were only five or six people. The various materials on the large conference table were in order. The forensic doctor Sun Jie was also here.

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

　　 Similar to what Bai Song had expected, Wang Huadong and Gao Chao were also assigned to the task force. Gao Chao was also one of the colleagues who came to Bai Song in the first term. In addition, Bai Song also saw a familiar face. It was not Wang Liang who came from the Sanlin Road Police Station, but Li Han, the police chief who dealt with the disputes he had seen before.

　　 Isn't this place enough? Send the sheriff out directly? Bai Song tut was amazed.

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

　　 This confidentiality agreement is mainly for external secrecy, for non-specialist team members, and for 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. He died almost a month ago and was about 25 years old. Apart from that, no other information was available. There was nothing on the deceased to prove his identity, and no recent missing persons were found to correspond with the deceased.

　　 The second aspect is the cause of death. The deceased died from a blunt weapon forcibly hitting the head. Dissecting the body is 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 plant in Tianbei District in the upper reaches of Tianhe, Tianhua City, which is undergoing asset restructuring. The chemical plant closed its doors last year, and all kinds of worthless things were piled up in the warehouse or the open space in the courtyard, which attracted some jealous brokers.

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

　　 After investigation, in Tianbei District, Tiandong District, and Jiuhe District, there have been more than a dozen waste collection stations where such iron barrels have appeared.

In addition, there is another clue that is barely useful. It is through chemical analysis and reports from the Tianhua University laboratory that there are fine gravel-like substances that are different from river sand in the corpses. The current inference is that The body was cut by a grinder.

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

The task of Bai Song and others is to collect the abrasives of the grinding wheels in the storefronts with grinders in the whole city. Each one only needs to be scraped off the grinding wheel, and finally they are collected and compared to the laboratory for final confirmation. Which brand of grinding wheel is, and then further investigation.

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

　　 A group of two, and Bai Song was put together with Li Han from Sanlin Road Police Station.

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

　　" What's the plan? "Li Han just drove into the car, and he vomited: "I thought we solved the case by pushing it bit by bit based on clues, but now it's better to find clues in a haystack."

　　" It may indeed be that there are too few clues. "Listening to Li Han's complaint, Bai Song didn't know how to answer it. UU read www.uukānshu.com and said vaguely. To be honest, although there are many styles of grinding wheels, the materials are actually the same. I must have done this kind of comparison before, but it is estimated that the comparison has not been successful.

　　Almost all the grinding wheels are common grinding wheels.

　　Is it possible that the person who installs doors and windows does not use the ordinary grinding wheels sold in the hardware city on the cutting machine, but also customized imports from foreign countries?

　　 Because of this, Li Han just complained about the significance of this work. However, the work is still unambiguous. After all, Sheriff Li is also a veteran policeman with seven or eight years of work experience.

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

　　 "Yes, we are classmates, and we knew each other since college." Bai Song nodded: "Sergeant Li, last time I went to the office and saw you deal with the 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 not bad, you graduates from good universities, the level is high."

　　 Listening to Li Han’s obvious compliments, Bai Songxin said that this is the money to buy the police chief Li? Why didn't he know what other advantages Wang Liang had besides playing games well and reading miscellaneous books?

　　 "Why, I don't have much level", Bai Song didn't answer this, "What's wrong with Wang Liang, you can tell me something."

　　Bai Song was curious, and he had a few conversations with Li Han 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 institute is that if no one signs up, then assign it.

　　 Last night, the station told policemen under the age of 35 about the situation.
