Young detective case book

Shao Ren was a little disappointed, and took a long time to let out a long breath: "I have been a policeman for seven or eight years, and I have never encountered such a cunning and cruel opponent. This is the fifth victim. Now I hear the phone ringing, and my heart Just beat the drums, afraid of hearing the news that the perverted killer is dispatched again, dreaming of bloody corpses."

Of course Suye understood how much pressure he was under and how heavy his heart was, and said in a deep thought: "The blood cross was definitely not left for no reason, if you crack it, maybe you can find the murderer."

"Oh? What do you think?" Shao Ren opened his eyes wide and looked at him questioningly.

Su Ye's white face was still expressionless, her eyes were dark and deep, she looked at the front blankly, and said softly: "I also think that the blood cross was left by Su Ya on her own initiative, so what is her intention? These days , I checked a lot of information. Well, in fact, the cross existed in ancient times. Its original meaning is to represent the sun. At the same time, it also symbolizes the tree of life, which is a reproductive symbol. The vertical bar represents male, and the horizontal bar represents Female. Later, the cross appeared in Mexico, Peru, and most importantly in Central America, alluding to the four winds, which are the source of rain. The cross was associated with Christianity very early, but it could not be used as a symbol of early Christianity Its broadest definition at that time was an ancient death penalty, which was popularly used in the Persian Empire, the Kingdom of Damascus, the Kingdom of Judah, the Kingdom of Israel, etc., to execute rebels, heretics, slaves and people without citizenship. In our China, where the cross reflects the earth in the ideogram, is an isoform with a box."

Shao Ren touched the chin that was stabbed by the burr, and frowned: "I really can't think of any of these contents that can be related to the murderer."

"That's right, it feels too far-fetched," Suye picked up a pencil and a notepad on the coffee table, sketched three crosses, tried to restore their shapes on the wall, stared blankly for a while, he Muttering, "I've always felt weird..."

"What's weird?"

"Why is the 'vertical' of the cross in the middle so thick?"

"Maybe when I wrote that stroke, the amount of blood dipped was more abundant."

"Normally speaking, it should be the first swipe with a lot of blood, right?" Su Ye had the same idea as Shao Ren at first, but he stayed in Su Ya's room just now, and re-perceived the scene of the crime from the perspective of the murderer. The more I feel wrong.

"I haven't tried it, but it's not important, is it?" Shao Ren said not too concerned.

Suye didn't make a sound, and continued to stare at the cross on the paper without blinking. After a while, he asked softly: "Apart from the ones left on the fence, did you find any other traces of forced entry? Or outsiders?" traces?"

Shao Ren shook his head: "We speculate that the murderer climbed in from the northwest corner of the wall, followed the path directly to the small building, and went up to the second floor from the external stairs. The door on the second floor is not locked, so there is no chance of encountering a murderer." What an obstacle. Like the previous cases, the scene was handled very cleanly, and no suspicious shoe prints or fingerprints were extracted."

Suye was silent for a long time, showing no expression.

Shao Ren suddenly came to his senses, and asked in surprise: "Don't you suspect that the murderer is from the Su family?"

Suye remained silent.

Shao Ren thought for a while, and then asked carefully: "Could it be that you think that the traces on the wall and the rags on the rose bushes were left on purpose by him to confuse our sight?"

After a long time, Suye said in a low voice: "Maybe it's not because he stays on purpose, but because he doesn't mind if he stays or not."

Shao Ren was a little dazed.

Su Ye explained, "Based on those clues, we will never find him. As for whether the scene was treated specially, I have reservations."

"Oh?"

"If he lived here, then no matter what traces he leaves, there will be no suspicion."

"What's the reason? What's your reason for making this judgment?" Shao Ren couldn't help questioning. To be fair, he was unwilling to accept Su Ye's speculation from the bottom of his heart.Even as a policeman who has seen too many ruthless criminals, he still can't imagine that the murderer will be a member of the Su family, leaving aside the other three victims. Do those bloody and cruel acts to Su Zhengting and Suya who are familiar to him or even relatives?

After a long time, Su Ye slowly answered Shao Ren: "Because this is the most reasonable explanation."

Shao Ren was dumbfounded.

After a while, Su Ye said again, "When I am doing math problems, if I really can't do it, I will look at the answer first and deduce it backwards, and it will become much easier to understand. Following this line of thought, you will think, Who is that suspect, most likely."

Shao Ren stayed for a while, as if thinking of something, his face suddenly changed, and he retorted instinctively: "Impossible! The person you suspect...he will never do such a crazy move!"

Seemingly expecting him to say that, Suye raised her eyes, looked at the "Virgin of the Rocks" hanging on the opposite wall, was in a daze, and after a long while, said in a low voice: "You've heard of Long Brosso's 'Natural born criminals theory'?"

Shao Ren was stunned for a moment, and said, "I remember that many experts in the legal field scoffed at his arguments of 'convicting crimes by appearance' and 'convicting crimes by genes', and criticized and refuted them."

Su Ye's eyes became a little confused, and he said slowly: "You have to be clear, Lombroso once engaged in the research of psychiatry and forensic science, he is a typical positivist. All his theoretical foundations are based on a large number of facts. That’s why he created the theoretical discipline of criminology more than 100 years ago, transferring the pure study of criminal behavior to the study of criminals. He is the well-deserved originator of criminology theory.”

Shao Ren was chilled by what he said: "You mean, the person you suspect is born with a criminal gene? Crime is his nature, not his will?" After thinking about it, I still feel that this It's really ridiculous, he scratched his head, "That man doesn't fit Lombroso's portrait of a 'born criminal'."

Lombroso believes that "born criminals" have physical and mental characteristics.Physiological characteristics refer to: flat forehead, protruding head, protruding browbones, deep-set eye sockets, large jaws, protruding cheekbones; uneven teeth, very large or very small ears, unevenness of the skull and face , strabismus, deformed fingers, lack of body hair, etc.Mental characteristics include: analgesia, visual acuity; gender indistinctness, extreme laziness, lack of shame and compassion, morbid vanity and irritability; superstition, preference for tattoos, habitual use of gestures to express consciousness, etc.
