Police Detective

　　 Bai Song pondered for a long time, and he understood, "The '12·01' task force, in these short ten days, has already entered the net work. At this time, the task force is very taboo against extravagance.

　　 stayed here all morning, and Bai Song also had some analysis of the case. At this time, the cause of death of the deceased also had preliminary laboratory results, and he died of hydrogen cyanide poisoning.

　　 Cyanide is a well-known toxic substance. Basically, things that are stained with the word "cyanide" are not undead.

　　Hydrogen cyanide, different from common sodium cyanide and potassium cyanide, is a colorless and transparent liquid. Using substances such as potassium cyanide, hydrogen cyanide gas can be produced by reacting with acid.

　　 The hydrogen cyanide liquid itself is easy to volatilize and has the taste of bitter almonds. When there is more than 0.003 grams of hydrogen cyanide gas per cubic meter of room, there is a risk of death to the human body. In theory, a Coke bottle, if filled with hydrogen cyanide liquid, is enough to kill 1,200 people.

The cyanide ion of hydrogen cyanide can greatly reduce the activity of more than forty enzymes in the human body, and quickly combine with the ferric iron in the oxidized cytochrome oxidase to prevent it from reducing to ferrous iron and interrupt the oxidation process of transferring electrons. , Tissue cells cannot use the oxygen in the blood to cause internal asphyxia.

　　 Since the central nervous system is most sensitive to hypoxia, the brain is damaged first, leading to death due to central respiratory failure.

　　 If you inhale a high concentration of hydrogen cyanide or swallow a large amount of cyanide within a short period of time, you will stop breathing and die within two to three minutes.

　　 No cyanide was found at the scene. As the door of the house was wide open, there was no cyanide residue in the gas in the house. The police who arrived at the scene the first time did not smell the so-called bitter almonds.

　　 Bai Song is not the police officer who sponsored the case. He has been thinking about one thing all morning.

　　If the level of forensic medicine in the city bureau is really high, then what is the reason for the conclusion that "there is a possibility of suicide"?

Professionals are not the same. Bai Song deeply understands the meaning of the phrase “specializing in surgery”. He never looks down on these professionals, but the intersection between them is really small, and Bai Song can’t go. ask.

After returning to the institute, Bai Song and Feng Bao had a chat. Feng Bao solved Bai Song's doubts. Many experts in large units usually leave room for words, and may leave a few more words on the scene where they are inaccurate. . Feng Bao's point of view Bai Song also thinks it is possible, but the case has already been committed, and the investigation must continue.

　　 In the afternoon, the master Sun Tang found Bai Song.

　　 "I just heard that the task force you want to go to will recruit people recently. Have you signed up?" Sun Tang asked.

　　 "No, I got to know it, the case is over, I don't sign up." Bai Song shook his head, thinking that Li Han's news is really well-informed.

　　 "It's over? Then don't go, it's boring to go." Sun Tang nodded.

　　 "Master, you said, why the case is about to be closed, but instead of recruiting people?" Bai Song didn't understand.

"Actually, it is not difficult to solve the case, to catch people, and even criminal detention is not difficult. The most difficult part of the case is the follow-up work." Sun Tang pointed to the books on the desk in the group: A large-scale telecommunications fraud case involves dozens of people, and there will be a lot of work in the later stage. It will be endless for a few months. The file can be piled on such three or four tables, and each one is so thick." Sun Tang used his fingers. After making a gesture, it was about five or six centimeters in size.

　　 Bai Song nodded and expressed his understanding that he had seen Wang Qianyi’s previous case involving the illegal sale of wild animals and how thick the file was. In a large-scale fraud case, the follow-up work is actually the big head.

　　 "Well, I still won't go. The business of handling cases can also be learned in the office." Bai Song expressed his understanding.

　　 "I called you over, one more thing, did Wei Suo ask you for help yesterday?"

　　 "Well, I followed Wei Suo on the case of stealing the battery of an electric bicycle in our group. I followed Wei Suo to catch two thieves."

"A young man like you, who lives in the office, must have some leaders like to ask you to work overtime. This kind of thing is still more dangerous. I still know you. You will not refuse this kind of thing. Second, you will definitely pay. Rush to the front. You can’t even wear a gun now. It’s indeed unsafe. "Sun Tang pointed to the southeast direction:" My child’s grandfather has moved to live with me, grandpa, and a small house. It’s about 50 square meters. It’s been idle for three years. It’s a sixth floor, and I can’t rent it for much. I’ve always been too lazy to get it. If you don’t dislike it, you can get some new mattresses and quilts, and you can just move in. I'll hire a housekeeping company to clean up the whole thing later."

　　"Ah? No, no, sir, how is this embarrassing? I am very good at the unit. Wei Suo actually exercises me. "Bai Song scratched his head.

"You can figure it out by yourself, just think about it yourself." Sun Tang finished talking about this, and then said: "Don't mention this thing~www.wuxiaspot.com~You can think about it when you look back, my house I’m too lazy to rent it, you decide for yourself. There’s one more thing, the murder case today, how do I think you’re interested in it?”

　　"En En!"Bai Song made no secret of his emotions.

"Well, okay, young man, it should be like this. If you want to get through everything properly and take care of yourself, you will have nothing to do." Sun Tang took out his notebook: "I just had a meeting in the office. This case is the chief investigator of the second criminal investigation team. It is reasonable to say that the office does not need to care about this matter, but our Sun Suo and Li Jiao both expressed that they would strictly investigate this case. , Also happened in our area, Sun Suo's face is definitely not bright.

　　 intends to set up a case-handling team. The members of the case-handling team will select one person from each group, and then the team will be led by Wei Suo and Xiao Wang Suo, a total of six people. People from each group did not leave the original team and followed the duty as usual, but the night shift was not arranged. When the shift was at night, they would go to bed as usual and do not need to get up for special matters. Therefore, they did not have compensatory rest the next day, and they had to continue to work with them.

This job requires a certain degree of enthusiasm, and the family pressure is not too great. I originally wanted to arrange for Feng Bao in our group, but his child is always sick at the age of two. , I'll report it to you. "

　　"Thinking, Master, I’m fine, I can follow the duty as usual at night, and I am also interested in the case." Bai Song looked a little excited.

"Haha, okay, you, young, that’s good." Sun Tang thought for a while: "It’s not right, few other young people have the enthusiasm of you. Okay, then I’ll report it to you. It's done, but it's a matter for the institute, for Sun Suo and Li Jiao to make faces.
