Criminal Investigation Files

It was almost two o'clock in the morning, and outside the police car, the police officers were still busy.

Inside the police car, Lu Siyu continued to analyze: "Most of the dual personalities, personality switching is uncontrollable. Only the emergence of stressors will cause fixed switching."

As Lu Siyu spoke, he closed his fingers and placed them in front of the sharpened jaw to support his chin. He continued: "The murderer's source of stress should be sex, because violence can no longer satisfy his inner desire, so at this time, the second personality Appeared. In the case of the murderer, although there were sperm spots, there was no direct trace of invasion, and the forensic doctor also inferred that the murderer may have a certain functional disorder."

Having said that, he paused and said, "In other words, he can only rely on that extreme method to obtain the ultimate pleasure. When he urgently needs it, there will be a personality switch."

Song Wen frowned and listened: "Now, what are the characteristics of these two personalities?"

If Zhuang Yi's theory was wrong before, then they should make a new profile of the murderer.

"Although the violent personality is violent, he has a simple mind, well-developed limbs, and finally a trace of conscience. He may look honest and reticent at ordinary times, but once stimulated, he will have a tendency to violence. The other personality is an epigenetic personality, and this personality is extremely abnormal. , very calm, smarter and more ruthless than the main personality..."

Lu Siyu deliberately slowed down his speech to let Zhuang Yi digest these inferences: "The murderer may have encountered some twists and turns when he was young. His childhood experience made him confused and distorted women, makeup, maternal love, and sex. In the self-characterization of the sub-personality, he thinks that he is a calm, confident and elegant person, and finally manifests as a special criminal pattern with a signature..."

Zhuang Yi nodded when he heard this, and murmured: "So the murderer with sub-personality will play with the police and treat the victim as a plaything."

"The act of covering the victim's face with clothes is just the murderer's personal signature. I think it may have something to do with the murderer's personal experience. This behavior has misled you." The wet clothes were stuck to the body, showing a cold look , but made Lu Siyu's thinking clearer.

"The violent personality is like strong limbs, and the abnormal personality is like a calm brain. Both personalities want to occupy this body, but it is obvious that the abnormal personality is gradually gaining the upper hand. He appears more and more, just needs violence The personality helps him control the prey. When the violent personality hesitates to kill the victim and wants to be released further, it is when the abnormal personality appears. I noticed that today’s girls are not seriously injured. It is very likely that This murder was planned from the beginning to the end by the abnormal personality, and the violent personality may not have appeared."

Song Wen often listens to Lu Siyu analyze these things, and has long been accustomed to his extraordinary intelligence.His voice was calm and cold, completely different from Zhuang Yi's usual sensational style, but it had a convincing power.

At this moment, Zhuang Yi's face was full of surprise and shock.When talking eloquently, Lu Siyu's whole person seemed to emit light, with a kind of magical power that made people surrender.

"I was able to think of this because Team Song reminded me." Having said that, Lu Siyu looked up at Song Wen.

Song Wen asked: "Did I raise the possibility of dual personality in the last meeting that inspired you?"

Lu Siyu looked at him with a pair of good-looking eyes: "Not only that, you pointed out one point before, in the first case we came into contact with, there were obviously many more marks on Li Ling's neck than in other cases. Caused. I just figured it out today. It was because the murderer activated his secondary personality after accepting the stimulus, and during the personality transformation, he became cognitively confused. That is to say, during the murder process, the two personalities The chaotic switching made him sometimes forget his purpose, where he was, and what he was doing, so the process of killing was repeated."

That is to say, when Li Ling was killed, the two personalities were still unstable and disordered. They used to intersect, and as he developed later, his perverted personality became more and more dominant, and began to occupy more and more parts of this body. initiative.

Lu Siyu paused for a few seconds before summing up, "Most people with split personalities or multiple personalities had imperfect childhoods, and his perverted personality should have been formed long ago. He has been sleeping for so many years and doesn't appear often. I I don't know what stimulated him, maybe it was from the first case, or maybe earlier, his abnormal personality awakened. It was the appearance of this sub-personality that turned him into a murderer."

Zhuang Yi asked again: "Then why did the murderer wear makeup? And why did he put makeup on the victim?"

"The murderer has hatred for women, which can be seen from the many violent injuries. But he is very proficient in makeup, and I think it comes from his self-cognition." Lu Siyu continued to analyze.

"The murderer may be born with a functional disorder, so he was not the same as a normal person since he was a child. He may have lost his mother when he was young. Make-up is a kind of gender inversion. He is recalling his mother and reflecting on himself at the same time. He thinks that he is not a complete man, and hopes that he can become a woman, that is, escape reality with a female identity. He regards makeup as a sacred and romantic step, just like the process of a caterpillar turning into a butterfly and spreading its wings. "

"Makeup is a means for the victim to achieve the perfect woman in the murderer's mind. During this process, he hopes that the woman is alive and quiet enough. He turned on the lamp in the dark night and carefully described the woman's face. Then he The strangulation begins, the woman wakes up and struggles, and he obtains the ultimate satisfaction. He is using this process to replace physical needs."

Up to now, all the details and process of the case have been analyzed by Lu Siyu.Some of them are deduced, some have not been confirmed, but most of them have theoretical basis, and all explanations sound reasonable.

"Your theory is very exciting, but... you... tell me this..." Having said that, Zhuang Yi tightened his hands on his trousers and clenched them into fists. This small movement did not escape Lu Siyu's eyes .

The person in front of him was hesitating, and Lu Siyu continued to speak: "I think some of your inferences are not wrong. It's just that the reality is more complicated. The girl was rescued, and we will get new testimony soon. my thoughts."

If his statement is corrected, then it can be proved that this profile is closer to the murderer.

Song Wen had been listening to them talking just now, and now he looked at Lu Siyu, and he understood what Lu Siyu wanted to do.

Sure enough, Lu Siyu said, "Professor Zhuang, if most of what I said now is confirmed, I hope you can face the media and give a new and complete profile of the murderer."

The matter has developed to this point, the police have been pushed to the cusp, it is better to break the boat and release all the information, so that everyone can find this perverted killer together.

"But, this is all your reasoning...Let me tell it, isn't it..." Zhuang Yi was still hesitating, he felt like a poor student who suddenly got a perfect score on the test paper.Right now, he really needs such a beautiful answer sheet. If this answer is correct, it may even become his life-saving straw.But he didn't feel at ease doing this, because after all, it relied on other people's analysis.

"It's no problem for me, I'm just a policeman, hoping to catch the murderer." Lu Siyu raised his head, his eyes were burning, "I think your name Ye Xiao and Ye Die, it's quite appropriate to turn it around .”

Lu Siyu has never been seeking utilitarianism. At first, he just hoped to correct his thinking, but now, the correctness of his thinking is no longer important. He seems to have been infected by Song Wen...

In the past, he seemed to be a solitary ghost in this world, living in a daze, unmoved by life and death, and only lived for one purpose, but after being around Song Wen, he began to care a little bit, and began to look at those ordinary people.He suddenly became interested in this criminal police game. With the accumulation of cases one by one, he was aroused to win, and he wanted to win more and more, and wanted to use his identity as a policeman to save more people.

He wants to catch the murderer.

At present, the murderer thinks that killing four people in a row should be the most proud and inflated time.Like a balloon inflated to the limit, only one needle is needed to reveal his original shape.

The murderer will soon know that the fourth girl is not dead.At that time, he would become distraught.

The person who tied the bell had to be untied. Zhuang Yi had already attracted the attention of the murderer before, and if he gave a correct profile, the shock to the murderer would be much greater.

Lu Siyu didn't care about how Zhuang Yi would get through his crisis and whether his reputation would be ruined.But he thought he needed to use Zhuang Yi's influence to attract more attention, destroy the murderer's confidence, and let him show his feet.

If the profile is accurate, they can even pick that person out of thousands of people.

After hearing Lu Siyu's words, Zhuang Yi pursed his lips. Song Wen saw his last hesitation and said, "Only the three of us know about today's conversation."

Zhuang Yi knew in his heart that the best way to restore his reputation was to revise the previous profile and give a correct answer.

Thinking of this, he looked out the window, it was still pitch black outside, everyone was busy, no one paid attention to the car parked in the corner.

Zhuang Yi finally nodded: "Okay, let's wait for the testimony of the surviving girl. If it proves that there is no problem, I can do it."
