Police Detective

"We have all studied modern history in books, and many of the teachers here have also experienced some changes in the times. Let's take Tianhua City as an example. I will talk about a few things that most people shouldn't have heard. It's not a horror. , Even some are commonplace.

　　 Our current living standards are getting higher and higher, and the pressure seems to be increasing. Have you ever known that the suicide rate was actually several times higher 30 years ago? Let me ask everyone first, the above hanging is an example. How do you think the hanging is done? "Bai Song asked.

　　 Everyone did not expect Bai Song to raise such a question first, but there were still many people who stood up and expressed their understanding.

　　 Find a beam, a rope, a table.

　　 This is almost everyone's understanding of hanging.

　　 Bai Song turned on the projector in the lecture theatre, here is a sketch, painted by Wang Huadong.

　　 There are four walls, no beams, no ropes. This is a black and white sketch, which is a bit depressing at first. In the middle of the picture, a woman is hung between the big cabinet and the kang head.

　　 This may be the cabinet where the woman married, or it may have been built later. The height is the same as the Kangtou, and it is less than 80 cm high. The cabinet is not good or bad in the sketch.

The gap between the cabinet and the kang head was only ten centimeters. The woman put her neck between the kang head and the cabinet, the strength of the upper body was pressed on a chopstick, her leg was half kneeling, and she was hanged to death by a chopstick in a daze. .

　　 "This is a chopstick." Bai Song pointed to the horizontal stick supporting the woman: "It's also a tool for hanging."

　　 This woman looks very skinny, and this posture and action makes people feel sad inexplicably when looking at it.

　　 This is even if you want to die, you can't find a decent way.

　　 All the students and teachers were in an uproar, they had never seen this!

　　 They only heard about the use of ropes, but they did not expect the poor to find the rope, or even the beam of the house, what to do!

"I think it's better than me to ask. Everyone has different experiences." Bai Song said: "Most of us are just like me, and will eventually become public security posts. For public safety, we have dozens of police officers. Years, will naturally experience the changes of the times. What I am talking about happened when the old policeman next to me went to work. Maybe you think this kind of thing will happen hundreds of years ago, in fact it was decades ago. I will show you this again. Look at this case."

　　 After that, Bai Song showed everyone a case of suicide by burning charcoal, which is now very representative.

　　 "See Weizhi, this term may have been heard by everyone. In the future work, everyone will have similar discoveries." Bai Song smiled slightly.

　　Some people nodded their heads seemingly understanding, but more people are still at a loss.

　　 "Inspector Bai, is this what you are talking about as a pattern?" a girl raised her hand and asked.

Bai Song thought for a moment: "Forget it, it doesn't count. There are times when manpower is exhausted. It is impossible for any of us to figure out all the people in the jurisdiction. It is impossible to understand the ins and outs of each case. Especially the police station, I believe that we All of my classmates are full of fighting spirit, but quite a few people will flatten your fighting spirit at the police station.

　　 every day, I don’t even have the qualifications to participate in a big case. Three to five years have passed in a flash. This is a very real thing. At that time, everyone is faced with buying a house and raising a family, and facing firewood, rice, oil and salt, the feeling is not so simple. We are all the same age, and I don't want to give you reason and spirit. However, if I can make everyone think a little bit before work, it will be very successful. "

　　 After finishing speaking, Bai Song clapped his hands: "The course has officially started. I will talk about criminal investigation today."

　　 This is also a textbook recently edited by Bai Song and others.

　　 Writing textbooks is actually not that difficult. Recently, they have bought all the similar books that are available on the market. None of them are written by frontline workers. There are a lot of theoretical things.

　　 Of course, these big guys are not divorced from reality. Many content, such as the use of special emotions, are well described, and Bai Song and others need to learn more.

　　 The cases that Bai Song told about today are all the cases that he has solved, and they are the ones that have gone beyond the confidentiality period.

　　 For example, the case of Yao Xin killing his father, if you want to tell it in reverse, it is:

"The filial piety of his children gave his father his birthday. The father ate the cake alone at home but caused the B bomb. After the scene was extinguished, all the evidence has disappeared. During the investigation, it caused a huge conflict between the children. The daughter killed his brother. .. What is all this..."

　　 Novel cases are written in such a reverse direction. They are written with some strange and suspenseful openings. From the perspective of God, the most incomprehensible things in this case are first shown to attract readers, and then they are slowly decrypted.

　　 Although this often makes people feel "but so" when solving the mystery, it really attracts the eye.

　　 It's a pity that Bai Song and others are not from this perspective. They deal with the case from the perspective of the police, and there is no way to proceed from the most suspenseful and interesting places first, but to advance one by one.

　　 As a professional criminal policeman, Bai Song has a good understanding of many cases. The leader of a case plays a vital role.

　　 For example, when handling any case, the investigation is divided into two parts, the first is the basic department, and the second is the research and judgment department.

　　The basic department is very simple~www.wuxiaspot.com~ which is something you can do in every case. For example, to check monitoring, call and chat records, personal evidence and physical evidence, site surveys, corpse identification, household water consumption, electricity consumption, purchase of unknown substances, car commuting, recent close contacts, neighbors The situation and so on.

　　 These are all to be checked. Major homicide cases can be investigated at all costs in investigating these basic issues.

　　 The second is to study and judge. These things become clues of meaning and value when you get them. They are not as intuitive as in the book, and you need to have a certain grasp of human nature.

　　 Bai Song originally thought that he could only talk for two hours, and the lesson plan he prepared was only two hours, unknowingly, it was already more than four o'clock, and the students were also fascinated by it.

　　 Many people went to the toilet halfway, but they still came back after going to the toilet.

　　 Although this is not his alma mater, Bai Song still unreservedly told about all his experiences over the past few years. These years, the future is the mainstay of Tianhua City.

"I'll stop here on the matter of the case. Modern investigative science is a broad and profound subject. Two days ago, my team members told you about on-site investigation, autopsy and the application of electronic computers. The three-day explanation will be there. Here, I hope it will be helpful to everyone." Bai Song bowed to everyone and ended the lecture.

　　 There was thunderous applause.
