Rebirth of the open female forensic doctor

Chapter 469 Crime Profile

Chang Que said, "In general serial murders, the murderer has a fixed motive, killing pattern, and killing target, which is not easy to change. This is because the serial killer's killing behavior is to satisfy a fixed ideal goal in his mind. , What is the reason why Cai Qianqian and Jarman were chosen as targets?"

"Ah, I thought of it, they are all women between [-] and [-], and both of them are engaged in art." Han Han's eyes lit up, and he said with a flash of inspiration.

"Well, this is the most obvious commonality between the two." Chang Dui nodded in agreement. Although one is a painter and the other is a sculptor, they are both in the realm of art.

"And they all have a relationship with Zhang Cheng." Qian Qian said weakly.

Everyone looked at him. This was true. Although Zhang Cheng was most likely not the real murderer, if there was anything in common between the two of them, it was that they both knew Zhang Cheng.

But such useful information is too little, and they can't figure out what the murderer's ideal goal is.

"Well, according to the existing information, let's analyze the psychological characteristics of the murderer from the perspective of 'criminal profiling', and try to see if we can describe the character and behavior characteristics of the murderer." Chang Dui thought for a while and said. .

This is also a method in the process of criminal investigation and case handling. Through the crime scene, the crime scene is reshaped in the brain based on direct or indirect data, simulating the psychological profile of the murderer at that time, and then analyzing the victims, thinking about why the murderer chose them, and finally analyzing As a murderer, think about planning from the perspective of a murderer, and understand and experience the satisfaction.

Combining these aspects, an image of the murderer is formed in the mind, which portrays the character and behavioral characteristics of the murderer, and sometimes even the appearance, age, and industry of the murderer...

This is not a metaphysics, but has the support of a variety of disciplines such as philosophy, biology, ethics, sociology and trace fans, and is scientific and feasible.

Gao Lele briefly described the whole story of the two cases through Ye Fan, and the sentence he said from the perspective of a bystander was actually an inadvertent point of view on the character of the murderer, which in turn aroused Ye Fan's suspicion of Zhang Cheng's criminal facts .

Because of doubts in his heart, Ye Fan rearranged the information and used reverse thinking methods to reshape the crime scene in his mind, simulating the behavior and psychology of the murderer, and then got an untenable result, inferring Zhang Cheng or not. Fierce conclusion.

This is the category of this 'crime profiling', but the real 'crime profiling' is more complex and comprehensive.

Ye Fan has been self-studying mostly in the field of forensic science. In fact, she is not a professional in criminal investigation. She just relies on her boldness, carefulness, and clever head to extract silkworms, deliberate on details, and use methods that are not as good as outsiders. to check.

This method of jumping out of the framework of criminal investigation and case handling sometimes does have unexpected effects. It interprets the case from another angle, which makes Chang Dui and the others admire her.

But when it comes to criminal investigation, she can't keep up with veteran criminal investigators like them, especially when it comes to complex criminal psychology. She has only seen some cases and has no theoretical basis at all.

"Then let's analyze the two crime scenes..." Team Chang stood up and walked to the left side of the meeting, where there was a whiteboard. He picked up a black oil-based pen, wrote Cai Qianxi on it, and said; "First Analysis from the scene of Cai Qianqian's case."

"I went to ask Meng Hang just now, and he answered clearly that his leather shoes have never used the brand of King Charlie, which is easy to find out. I don't think he lied. I can be sure that they were left by the real murderer. "Han Han said first.

"The murderer was wearing leather shoes at the time. Ordinary young people don't know how to wear leather shoes. Students can be excluded. There is a school. The murderer must be very familiar with the school's teaching room if he was able to lay out such a clever murder in a short period of time. If they are not students, then only the teachers and professors of the school, as well as property management, administrators, security guards, and even cleaners may wear leather shoes." He Pingfei continued.

"It shouldn't be a low-level property. King Charles shoe polish is expensive, and it is not affordable for the ordinary low-level class. I am more inclined to the teachers, professors, and even leaders of the school." Su Liang added, paused and said : "If you use such expensive shoe polish, the leather shoes you wear should also be of a big brand, and you should be a person who has certain requirements for the quality of life."

Team Chang immediately wrote down on the whiteboard, Occupation: University teacher, professor, leader, Age: Over 30 years old, Pursue a certain quality of life.

Ye Fan thought of what Gao Lele said, and said, "If Zhang Cheng is not the murderer, then the platinum necklace that appeared at the scene of throwing the body in the wilderness must have been deliberately planted by the real murderer."

"Zhang Cheng once said that when he was sad that night, he drank his sorrow by drinking alone in the lover's lake. After drinking, he threw the necklace into the lake in anger. He was very sure that he did throw it on the lake."

"I have been to the lover's lake in the art school. There is a promenade there. Zhang Cheng drank in the promenade that night, but there was a buffer grass between the promenade and the lake. Because he was drunk at the time, his hands and feet In a weak state, he may not have thrown that necklace into the lake, but dropped it on the grass, and was picked up by the real murderer."

"Well, Ye Fan's conjecture is reasonable, and it has solved the doubt of the necklace very well. So, the real culprit has long been planning to let Zhang Cheng take the place of the dead ghost?" Chang Dui nodded in agreement with Ye Fan's conjecture, Originally, the clue of the platinum necklace was a suspicious point that made no sense at all.

If Zhang Cheng was the murderer, taking away the diamond and replacing the platinum necklace would be a foolish act of exposing his shortcomings, and he said afterwards that he threw it into the lake. Isn't this even more suspicious? It's all good in the corner, and it's easier to clear yourself of suspicion than throwing it into the lake.

But last night Ye Fan mentioned that Zhang Cheng was not the real murderer, so Zhang Cheng did not lie. How did the real murderer fish the necklace from the lake of lovers?

But as Ye Fan said, it can be explained. When Zhang Cheng was drunk, the real culprit must be nearby.

"No." Ye Fan shook his head and said: "The real murderer wanted Meng Hang to be a scapegoat at the beginning. The first step was to let Meng Hang bear the murder charge, but now that I think about it, Zhang Cheng was lured by the dark murderer to do these things."
