Just when I thought that my reasoning would soon find the suspect, one day later, Ye Qian brought two pieces of news, one good and one bad.
The good news is that through investigation, only a home decoration company called "Meidu Concept" in Yunxi City met the requirements. This company is the leader in the home decoration industry in our city, with branches all over the city. Their home decoration concept is famous for being "the best and fastest".
Anyone who has ever renovated a house knows that some casual workers usually do the work of several houses by themselves in order to get work, which will cause the decoration time to be postponed indefinitely. There is no need to worry about this when choosing Mido Concept. Each type of work has strict working hours, which will be written in the decoration contract. If workers delay the construction period during the decoration process, they will be compensated for losses. According to our investigation, their company's bricklaying construction period is exactly one week.
The bad news is that their company is too big and has almost eaten up 40% of the entire Yunxi City market. There are hundreds of qualified bricklayers and small workers in their company. If they all go to Lao Xian to do DNA Inspection, on the one hand, the cost of handling the case is too high, and on the other hand, we are afraid of alerting the enemy, so we can only investigate in secret to find those who meet the conditions.
According to the feedback from the visit, under normal circumstances, the income of bricklayers is not bad. According to the market situation in Yunxi City, it is two hundred yuan a day. With this income, even if they have land for planting at home, they will not be able to harvest it by themselves. After all, it costs to harvest one acre of land. It¡¯s only a few dozen yuan, and they won¡¯t lose the watermelon and grab the sesame seeds.
There is another type of person among bricklayers, called Xiaogong. This is also a type of person that I have not understood before. If we want to understand the job type of laborer in detail, we must first talk about bricklaying. Generally, in the process of home decoration, building walls, laying wall tiles and floors all belong to the category of bricklayers. This is a job that tests your skills extremely. It is impossible to do it right away after just a few years of practice. If you knock someone¡¯s wall apart, they won¡¯t pay you, and they even destroy your own sign. . So don¡¯t think that the village chief is not a cadre. In fact, bricklayers are an occupation that is in short supply, which is why their wages are so high. If you work for a decoration company, a bricklayer can earn more than 7,000 yuan a month plus bonuses. You must know that the police in our city only earn less than 3,000 yuan a month for their hard work. This comparison shows the difference.
If you want to become a qualified bricklayer, you must start from a small job in the first few years. The main job of a small worker is to make cement for the bricklayers, carry mud bags, and do some physical work. Their salary is three yuan a day per person. ten yuan. Although the salary is very low, many people are willing to do it if they can learn skills. But this kind of small work is rarely done by urbanites. After all, this kind of work does not have a very good reputation in our local area. Usually when someone talks about someone who is carrying a bag of mud, they often think that this person has no future. (Only represent local views, do not take them online.)
Based on the previous reasoning, the target was directly narrowed down to the small workers. According to the situation in our city, basically one bricklayer leads two small workers, so after another layer of sorting, there are still more than 60 people listed. within the scope of suspicion.
Just when Ye Qian and I were at a loss what to do, Brother Ming excitedly called us to the conference room again.
When we sat down, Brother Ming took out a tool directly from behind and threw it on the table. The entire tool was composed of thread-shaped high-carbon steel wire. The shape was a bit like the number "9". The tool had a buckle at the node position.
"Could this be" I widened my eyes.
"Yes, this is the suspect's crime tool!" Brother Ming said straightforwardly.
"Do you know who the suspect is?"
¡°Not sure yet!¡±
"We have found all the tools for committing the crime, why are we still not sure?" I find it a bit strange.
"I bought this tool!"
"What? Bought it? Where did you buy it?" This result made me a little stupid, because according to our previous analysis, the suspect might have made a homemade crime tool. Now this kind of tool can be bought on the market. Of course I was surprised.
¡°I only learned the true purpose of this thing after receiving advice from seniors on the forensic forum.¡± Ming Ge said frankly.
In the Public Security Bureau, we all belong to the technical police. Since we are all engaged in technology, we police officers must have communication together. We have a special communication platform within us for forensics, trace examination, physical and chemical biological examination, criminal examination, etc. Photography, document inspection, as long as it is a criminal technology field, it is covered. There are elites from all over the country, such as Ming Ge, who are really numerous. For example, the head of our trace detection platform is also a trace detection expert of the Ministry of Public Security. While we were still studying fingerprints and footprints, he had already begun to study lips.??Made with voiceprint. In other words, the knowledge we have now is all summarized by them.
"What is this thing used for?" Ye Qian's words drew my attention back to this strange thing.
"Livestock hooves! Most of us won't use them, but veterinarians are no stranger to this. In rural areas, when large livestock such as pigs, cows, and donkeys are sick and need injections, people need to cover the hind hooves of the animals first. It prevents veterinarians from being harmed during treatment. Most people will not buy this kind of thing, and only people who help veterinarians will buy it."
"Due to development in our city over the years, a lot of cultivated land has been built into residential areas, and there is less and less grassland for livestock to eat. Therefore, most of our rural people here almost no longer raise large livestock, but treat the livestock. There are only a handful of veterinarians in our city.¡±
"I spent a lot of effort to buy this livestock muff. I learned from the sales boss that in our entire Yunxi City, there are only two villages that are still raising large livestock. One is Peach Blossom in the west of our city. The other village is Niulangang Village in the southwest. The two villages are fifty kilometers apart, both are close to the subsidence area, and each village has a part-time veterinarian."
"According to my inference, it is impossible for veterinarians to find helpers who are too far away. They are more likely to find people from the same village. I searched according to the place of residence and found that among the suspicious sixty-six workers, four of them had The registered address is Niulangang Village, and if our reasoning is completely correct, the suspect should be one of the four of them."
"His grandson is finally coming to the surface!" I clenched my fists in excitement and swore.
"Ye Qian, go and bring Jiang Tonghai, Jiang Tongjun, Jiang Lianhong, and Jiang Yimin over. Guoxian, how long will it take you?"
"Two hours at most!" A white light flashed on Lao Xian's glasses.
¡°Four people were summoned to our department at 12 noon. At two o¡¯clock in the afternoon, as the door of Lao Xian¡¯s laboratory opened, the suspect Jiang Lianhong was locked.
After the DNA comparison, Jiang Lianhong was immediately controlled. Under the leadership of Brother Ming, our department began to search the suspect's residence. We found an incense burner enshrining the portraits of his parents and a foot-operated manual thresher in his home. The livestock gaiters used in the crime and a square fish pond 20 meters south of his residence. After the search here, a group of us quickly returned to the criminal police team and prepared for interrogation based on the physical evidence currently available.
