Xu Jiuyan quickly wrote down Guan Zheng's words and said: "Living people have expressions and subconscious behaviors, and they can judge their psychological state, but dead people don't have any movements, how can you see it?" ”

Guan Zheng said: "The living person is the criminal mind, and the dead person is the traditional criminal investigation. Pen ~ Fun ~ Pavilion www.biquge.info"

"Would you still use traditional criminal investigation?"

"What wouldn't I? Listen, the length of a human foot is one-seventh of the height of a person's hand, and the length of an adult man's palm is between 20 and 24 centimeters, and after I measured it with my palm, it was about 23 centimeters, which is about 160 centimeters.

According to the standard formula, it is 160 minus 105, which is 55 kilograms, and in terms of appearance, the deceased is on the thin side, that is, 45 to 50 kilograms.

The red skirt of the deceased's coat is Montejiao, one of the top 10 women's clothing brands in France. But according to the deceased's underwear brand, it is a low-cost unknown brand. This can show that she has a glamorous appearance, but in fact she has no financial strength.

And a woman with a good face and no economic strength, but a glamorous appearance, generally does that kind of work. According to the time of death in the hands of the small circle, she did not return all night, but no one reported the crime.

There are several possibilities. She must not be living with her family, because if it were family, she would definitely try to find it, but she was not cared for, so she lived outside by herself. For her, if she doesn't have the financial strength, she can only share a house.

She didn't return all night and didn't report the crime, which shows that this is the norm, which is not surprising at all, and shows that her circle of friends is very small, so to speak, there are no friends at all. That's it! ”

Guan Zheng has finished his reasoning, and Xu Jiuyan is still calculating the height of the deceased, how can it be considered wrong?

Guan Zheng saw that Xu Jiuyan was still in the vertical position, sighed and said, "You are hopeless, mathematics is taught by the physical education teacher, right?" ”

Xu Jiuyan was still persistently calculating, grabbing Guan Zheng and asking, "How is this calculated?" ”

Guan Zheng continued: "If you don't know how to count the length of your feet, you can grow it with your hands. Hand length is one-ninth of height. ”

"That's not right, why is it getting smaller and smaller?"

Guan Zheng raised his forehead and said: "You use multiplication to calculate, of course, the more you calculate, the smaller it is, you don't understand this logical relationship?" Did you know that there's something in the world called a calculator? ”

Xu Jiuyan glanced at him and said, "I can use my brain to calculate!" ”

"Alright, don't forget it, come and see the corpse."

Xu Jiuyan walked over and said, "What are you looking at?" ”

"What do you say? How many times have you been out of the scene, and you still ask me what to watch? Tell me, what do you think? ”

Xu Jiuyan squatted down and said: "Judging from the age of the victim, the age of the murderer should be between 25 and 35 years old, because single men of this age are more likely to get pleasure in the process of committing the crime, thus highlighting psychological pathology."

The deceased was about 50 kilograms, and there were no particularly deep footprints in the vicinity, or traces of dragging, indicating that the murderer was probably between 65 and 75 kilograms. As for height, it's not easy to judge, right? ”

"Why?" This time, the change of customs and politics asked a question, and Xu Jiuyan said: "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?" ”

Jiuyan pursed her mouth: "You are experienced, you will know it by guessing." ”

Guan Zheng shook his head and said, "That's not the case, just like you just said, the murderer's figure is definitely not too thin, but the murderer chooses to control the victim's ability to move first."

It shows that the murderer is not sure enough 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 that the murderer is between 170 and 180 centimeters tall. ”

Xu Jiuyan nodded and said, "That's it, why didn't you say it earlier?" ”

Guan Zheng smiled and asked, "What else do you want to say?" ”

After thinking for a while, she shook her head and asked, "Why did the murderer choose here?" Is it because it's convenient? Or do you use local materials?

This is obviously a deliberate killing, but why did the murderer choose this victim? What angered him? Why did the murderer send you a painting? Is it a demonstration to you, or is it trying to get attention? ”

Guan Zheng listened to Xu Jiuyan's series of questions and said, "That's what I mean, you can't get a proper answer without a clear question." When you ask the right questions, you're sure to get the right answers. ”

Xu Jiuyan looked at Guan Zheng and said, "Then what I said is right?" ”

Guan Zheng nodded and said, "That's right!" ”

Xu Jiuyan was just about to celebrate, when she heard Guan Zheng say: "However, I have something 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 hit by a female *** or hit in his childhood, and this is the reason why he committed the crime.

The location of the crime is exactly the same as what I said, which means that this location was prepared a long time ago and was not chosen randomly, so it should have been forcibly brought here and killed.

In the choice of the victim, his goal must have a certain degree of similarity with his inner image, or he is pursuing the likeness to the greatest extent. I know so much so at the moment, and the rest will continue to be forensics. ”

Li Chongyang came back from the monitoring room and said: "The surveillance basically didn't capture anything. ”

"Is there a blind spot in the surveillance, or is it broken?"

Li Chongyang shook his head and said, "No, the monitoring is intact, but because this monitoring is old-fashioned, there is no way to rotate." ”

Guan Zheng said: "Impossible, as long as someone does it, there will be traces, and as long as the monitoring is still there, there must be no problem."

The shooting angle of the surveillance is usually between 60 and 120 degrees, and as a public place, the monitoring equipment here must be able to ensure that every corner is seen. It's not that you didn't shoot anything, or you just didn't notice it. ”

Li Chongyang crooked his mouth and said, "Then you are optimistic about it yourself?" ”

Guan Zheng glared at Li Chongyang and said, "You are so bold that you dare to instruct me?" ”

"Then I can't see it, what do you want me to do? I've watched it 6 times. ”

Guan Zheng took the computer, looked at the monitoring of the time period of death twice, and said, "Go check this shadow." ”

"Huh? This shadow? How do you check the shadow? ”

Guan Zheng pointed at Xu Jiuyan and said, "Let her go." Let her draw this, and restore the clear appearance as soon as possible. ”

Xu Jiuyan looked at the almost unrecognizable shadow on the screen and said, "How do you draw this?" Not even a shadow. ”

"Use simulation software first, try to restore the outline as much as possible, and then visit to find the most similar person."

Xu Jiuyan nodded and said, "Okay, I'll try." ”
