Chapter 8 Chapter VII

Wang Gedong, the deputy director in charge of criminal investigation of the County Public Security Bureau, walked over with a gloomy face, and waved to Lao Chen, the head of the forensic team who was busy inside. "Boss, you are here." "How many died?" Wang Gedong frowned. "Four people may have died, because the scene was so badly bombed that the bodies couldn't be assembled. I heard that there were four people in the explosion site. Sixteen people were injured to varying degrees, and five of them were seriously injured. They are still being rescued." "Can it be saved?"

"Ask the doctor, it's probably impossible to die." Wang Gedong pressed his temple and exhaled: "It's so awesome, who did it?" "I don't know. The criminal investigation team is still investigating. I only know that it was an explosive explosion." "What explosives?" "It's still not completely determined. It is necessary to continue to analyze the reaction products before and after the explosion. Now that the analysis is halfway done, I think it should be trinitrotoluene." "TNT? What the hell is this?" "TNT."

Wang Gedong's eyes lit up immediately. He forgot that TNT's full name is trinitrotoluene. When he heard the word "TNT", as if cold water was being poured on him, he asked in a deep voice, "Military explosives?" "Military use is more, and many civilian blasting projects also use this." Wang Gedong handed Lao Chen a cigarette, lit it himself, thought for a while, and asked, "Did the murderer be killed by the bomb, or did he escape?" "I don't know. I heard that the criminal investigation team is still taking records of the wounded in the street office. I don't know what happened in the morning."

Wang Gedong thought for a moment, then asked: "Is trinitrotoluene available in the market?" Old Chen said: "This thing is more strictly controlled than a gun. The construction unit has strict supervision on how much it buys and uses. In the past cases of this kind in our province, all the gunpowder was used. The power of the gunpowder is limited and the stability is poor. In many cases, the murderer only blew himself up. I've never seen a TNT kill." Wang Gedong squeezed the butt of the cigarette and said, "Isn't it homemade gunpowder?" "Well, this thing is very simple, just buy some materials, or get it from fireworks."

Wang Gedong said: "What about TNT, can it be self-made?" Old Chen shook his head: "It's very difficult. Fuming nitric acid and concentrated sulfuric acid are needed, and industrial equipment is needed. I probably can't make it myself." Wang Gedong nodded: "Okay, you continue to work, and I will find out the situation with other people." After thinking about it, he decided that this case has a great impact, and now the county has mobilized all relevant departments to block the news, but obviously this kind of thing cannot be suppressed at all.We need to solve the case as soon as possible and find out the facts.

What we have to do now is to wait for Lao Chen to finally confirm the composition of the explosive. If it is really TNT, we need to go to the relevant places in the surrounding counties and cities to check it out.For another piece of work, first ask the criminal investigation team about the latest investigation progress. He walked towards several offices of the criminal investigation team, but before he got there, the captain Lin Jie ran up to him and said anxiously, "Boss, the murderer should be located." "Oh, so fast?" Wang Gedong was a little overjoyed, he didn't expect to know the murderer in only half a day.

Lin Jie said: "In the morning, the town signed the agreement with the He family. It was the He family that Jiang Ping got rid of. It was the daughter-in-law of the head of the household who signed the agreement. At that time, there were four people in the office. Except Gan Jianing, they were the deputy mayor Li Gang and Jiang Ping. , and Lu Weiguo, the director of the street. All four died on the spot. Of course, the corpses were completely shattered and charred, and you couldn’t find a single finger, but it’s impossible to escape in this room. We also asked other people to confirm There were only four of them in the room at the time. The explosion came out of that office. We checked the surveillance, and Gan Jianing was carrying a shoulder bag at the time. I couldn’t see what was in the shoulder bag. I guess it was explosives. After that, we checked Gan Jianing’s resume, she was a student of the Chemistry Department of Zhejiang University more than ten years ago, I looked through her school documents, and found that several of her papers were about explosive technology, and she is very proficient in the production of explosives.”

"This..." Wang Gedong obviously didn't expect that a woman made explosives to fight with them, and then he sneered, "Jiang Ping, an idiot, deserves to die. If someone didn't protect him, I would have destroyed him long ago. That guy Li Gang is nothing. Good thing. But this Lu Weiguo, I heard that he has a good reputation among the common people, this matter has nothing to do with him, hey..." He thought for a while, and continued: "Now the case is basically clear, so you can get a search warrant and go search He's house. Later, you will report the criminal motive, the crime process, and the surveillance video, and the case will be closed. Talk to your superiors in a few days After communication, decide when and how to announce it to the public."

Lin Jie said, "Okay, I'll do it right away." Afterwards, Lin Jie led people to search He's house, found various chemical equipment and leftover materials, and found TNT particles left in the house. The county bureau then sent people to visit the relevant material sales outlets. Most of Gan Jianing's materials were bought from the agricultural materials market and middle school chemical sales outlets. The store also confirmed that this woman came to buy things a few days ago.Gan Jianing made TNT explosives through repeated purification and chemical reactions of various chemical fertilizers, nitric acid, sulfuric acid, and pesticides he bought.

The structure of the whole case is clear, the criminal motive is clear, and the evidence is conclusive. The murderer and the victim died together, and the family of the murderer didn't know about it, so there was nothing to think about how to measure the sentence and how to compensate in the future. When the county announced it to the public, they encountered some troubles. They couldn't say that the man from the He family was caught at the police station and finally returned with an urn, so that the heroine was furious and blew up. After a unified caliber, it was announced that Gan Jianing had a weird personality, didn't talk to people very much, and had a serious mental illness. At the same time, her life was not satisfactory, and her married life encountered serious obstacles, so she hated the society.The evidence is that she also scolded the government a few times in online comments and threads a few years ago, and made fun of her married life.

The county has also deployed more staff to increase the scale of stability maintenance. In recent weeks, it has controlled the public opinion media, especially preventing foreign media from having the opportunity to interview Gan Jianing's family. Anyway, the case was closed. They thought the matter was over, and things quickly calmed down. But they didn't know that he was back. In his eyes, what Gan Jianing was playing was childish. Xu Zeng said that the man had an IQ of 160. Although he had never tested his IQ, it should not be too low. When he was a student, classmates in the Department of Chemistry jokingly called Gan Jianing the "Queen of Chemical Engineering". If there is a "Queen of Chemical Engineering", then he must be the real "Pope of Chemical Engineering". However, he doesn't like the tragic way of explosives. If you want to do it, do it high-end!
