Xu Jiuyan quickly wrote down the government's words and said: "Living people have facial expressions and subconscious behaviors, and can judge their mental states, but dead people have no actions. How can you tell them?"
Guan Zheng said: "Living people are criminal psychology, and dead people are traditional criminal investigations.
"Do you still use traditional criminal investigation?"
"What am I not? Listen, the length of a person's feet is one-seventh of the height, and the palm length of an adult male is between 20 and 24 cm. After I measured it with my palm, it was about 23 cm. , About 16o centimeters.
Calculated according to the standard formula, it is 16o minus 1o5, which is 55 kilograms. From the appearance, the deceased is thinner, which is 45-50 kilograms.
The red dress of the deceased is Montagut, one of the top ten women's clothing brands in France. However, according to the underwear brand of the deceased, it is a cheap and unknown brand. This can show that she has a glamorous appearance, but in fact she has no financial strength.
A woman with a nice face and no financial strength, but a glamorous appearance, usually does that kind of work. Based on the time of death in Xiao Quaner's hand, she did not return all night, but no one reported the crime.
There are several possibilities for this. She must not live with her family, because if she is a family, she will try her best to find it, but she has no one to care about, so she lives outside by herself. For her, without financial strength, she can only rent a house together.
She didn't report the crime all night, which shows that this is the norm, which is not surprising at all. It shows that her circle of friends is very small, and it can be said that she has no friends at all. That's it! "
Guan Zheng has finished his reasoning, and Xu Jiuyan is still calculating the height of the deceased. Why is it wrong
Guan Zheng saw that Xu Jiuyan was still making upright poses, and sighed and said, "You are hopeless. The math was taught by the physical education teacher, right?"
Xu Jiuyan was still making persistent calculations, clutching Guan Zheng and asking, "How exactly is this calculated?"
Sekisei continued: "If the length of your feet is not counted, you can use your hands. The length of your hands is one-ninth of your height."
"That's not right, how come it gets smaller and smaller?"
Guan Zhengfu said: "You use multiplication to calculate, of course, the smaller the calculation, you don't understand this logical relationship? Do you know that there is something called a calculator in this world."
Xu Jiuyan gave him a white look and said, "I can do it with my head!"
"Alright, don't forget, come and see the corpse quickly."
Xu Jiuyan walked over and said, "What are you looking at?"
"What are you talking about? How many times have I been to the scene and asked me what to watch? Tell me, what do you think?"
Xu Jiuyan squatted down and said: "From the age of the victim, the age of the murderer should be between 25 and 35, because single men in this age group are more likely to get pleasure during the crime, which highlights the mental illness.
The deceased was about 5o kilograms, and the nearby footprints were not particularly deep, or traces of drag, indicating that the murderer was probably between 65 and 75 kilograms. As for height, it’s not easy to judge, right? "
"Why?" Xu Jiuyan asked a question after the change of customs policy. "From the scene, there is no reference, and there is no way to judge the height."
Guan Zheng raised the corners of his mouth and said, "Then do you know why I give the range accurately every time?"
Xu Jiuyan squatted her mouth: "You have rich experience, you'll know after a guess."
Guan Zheng shook his head and said, "This is not the case. As you said earlier, the murderer will certainly not be too thin, but the murderer chose to control the victim's ability to move first.
It shows that the murderer did not have enough confidence to control the victim, which means that the murderer will not be too fat. According to the formula I just gave you, it can be reversed. The height of the murderer is between 17o and 18o centimeters. "
Xu Jiuyan nodded and said, "Well, why didn't you say it earlier?"
Guan Zheng smiled and asked, "What else can I say?"
Xu Jiuyan thought about it, shook her head and asked, "Why did the murderer choose here? Is it because of its convenience? Or is it local
This is obviously a deliberate murder, but why did the murderer choose this victim? What irritated him? Why did the murderer send you a painting? Is it to demonstrate to you, or do you want to get attention? "
Guan Zheng listened to Xu Jiuyan's series of questions and said, "That's what I meant. If you don't have a clear question, you can't get the right answer. When you ask the right question, you will definitely get the right answer."
Xu Jiuyan looked at Guan Zheng and said, "Am I right?"
Guanzheng nodded and said, "It's all right!"
As soon as Xu Jiuyan was about to celebrate, she listened to Guanzheng and said, "However, I still have to add to the basket of questions you raised.
The murderer's working hours are very flexible, and his marriage has changed dramatically recently, and he was even beaten by a female *** or assault in his childhood, and this is why he committed the crime.
The location of the crime was exactly the same as what I said, indicating that this location was prepared a long time ago and was not chosen at random, so it should have been forcibly brought here and then killed.
In the choice of the victim, his goal must have a certain degree of similarity with his own inner image, or he is pursuing similarity to the greatest extent. I know so much so far, and others will continue to collect evidence. "
Li Chongyang came back from the surveillance room and said: "The surveillance basically didn't capture anything."
"Is there a dead spot in the monitor, or is it broken?"
Li Chongyang shook his head and said: "Neither, the monitoring is intact, but because the monitoring is old-fashioned, there is no way to rotate it."
Guan Zheng said: "It is impossible. As long as someone does it, there will be traces. As long as the monitoring is still there, there must be no problem.
The shooting angle of surveillance is usually between 6o and 12o, and as a public place, the surveillance equipment here must be able to see every corner. Either nothing was taken, or you didn't show it. "
Li Chongyang tilted his mouth and said, "Then you are optimistic about it?"
Guan Zheng glared at Li Chongyang and said, "You are so courageous, you dare to instigate me?"
"Then I can't see it, what do you want me to do? I have watched it 6 times."
Guan Zheng took the computer, watched the monitoring of the time of death twice, and said, "Go check this shadow."
"Ah? This shadow? How do you check the shadow?"
Guan Zheng pointed to Xu Jiuyan and said, "Let her go. Let her paint this, and restore it to a clear look as soon as possible."
Xu Jiuyan looked at the almost indistinguishable shadow on the screen and said, "How do you draw this? It's not even a shadow."
"First use the simulation software, try to restore the outline, and then visit to find the most similar person."
Xu Jiuyan nodded and said: "Well then, I will try." (End of this chapter)
