At this time it was almost two o'clock in the morning, outside the police car, the police officers were still busy.

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

While talking, Lu Siyu closed his fingers and placed his chin in front of the sharpened jaw. He continued: "The stressor of the murderer should be sex, because violence can no longer satisfy his inner desires, so this is the second personality. Appeared. In the case of the murderer, although there were sperm spots, there was no direct trace of invasion. The forensic doctor also concluded that the murderer may have a certain functional disorder."

Having said that, he paused for a moment, "In other words, he can only rely on that extreme way to get the ultimate pleasure. When he needs it sharply, a personality change will occur."

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

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

"Although the violent personality is violent, it has a simple mind, well-developed limbs, and a trace of conscience at the end. He may usually look honest and reticent. Once stimulated, he will tend to be violent. Another personality is an epigenetic personality, which is extremely abnormal. , Very calm, smarter than the master, and more ruthless..."

Lu Siyu deliberately slowed down his speech, allowing Zhuang Yi to digest these inferences: "The murderer may have encountered some twists and turns when he was a child. Childhood experience made him confused and distorted about women, makeup, maternal love, and sex. The sub-personality that came out in the self-determination, thought that he was a calm, confident and elegant person, and finally embodied in the iconic special crime pattern..."

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

"The act of covering the victim's face with clothes is only the personal signature of the murderer. I think it may be related to the personal experience of the murderer. This behavior misled you." The wet clothes were attached to the body, showing coldness. , But made Lu Siyu's thinking more clear.

"The violent personality is like strong limbs, and the perverted personality is like a calm brain. Both personalities want to occupy this body, but it is obvious that the perverted personality is gradually dominant. He appears more and more often, but he just needs violence. 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 have noticed that the injuries suffered by today’s girls are not serious. This murder was planned from beginning to end by perverted personality, and perhaps no violent personality appeared."

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

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

"I can think of this, but the Song team reminded me." Lu Siyu said here, looking up at Song Wen.

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

Lu Siyu looked at him with a pair of nice eyes: "Not only that, you pointed out one point before. In the first case we came into contact with, the marks on Li Ling's neck were obviously more numerous than in other cases. It was repeated suppression. Cause. I just figured it out today because after the murderer received the stimulus, he stimulated the sub-personality. During the personality transformation, there was cognitive confusion. In other words, in the process of that murder, there were two kinds of personality. The chaotic switching makes him sometimes forget his purpose, where he is and what he is doing. Therefore, the process of killing has been repeated."

In other words, when Li Ling was killed, the two personalities were still unstable and disordered. They once crossed over, but as they developed later, his perverted personality became more and more dominant and began to occupy the body more and more. initiative.

Lu Siyu paused for a few seconds before summarizing, "Most of the split personality or multiple personality have imperfect childhoods. His abnormal personality should have formed long ago. He has been sleeping for so many years and he does not appear often. I don't know what irritated him, maybe it was from the first case, or maybe earlier, his abnormal personality awakened. It was the appearance of this personality that made him a murderer."

Zhuang Yi asked again: "Then why does the murderer put on makeup? Why does the victim put on makeup?"

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

"The murderer may have a natural functional disorder, so he has been different from normal people since he was a child. He may have lost his mother when he was young. Make-up is a gender inversion. He is reminiscing about his mother and reflecting on himself. He believes that he is not a complete man, and hopes that he can become a woman, that is, to escape reality with a female identity. He regards makeup as a sacred and romantic step, like the process of a caterpillar turning into a butterfly and opening its wings. "

"Make-up is a means for the victim to achieve the perfect woman in the murderer's mind. In the process, he hopes that the woman is alive and quiet enough. He is in the dark night, lighting up the lamp, carefully depicting the woman's face. Then he After strangling, the woman wakes up and struggles, and he gets 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 inferred, some have not been confirmed, but most of them have theoretical basis, and all explanations sound reasonable.

"Your theory is wonderful, but...you...tell me this..." At this point, Zhuang Yi tightened his hands on his trousers and clenched them into fists. This little gesture did not escape Lu Siyu's eyes. .

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

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

Song Wen had been listening to them just now. At this time, he looked at Lu Siyu. He somewhat 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, and the police have been pushed to the cusp of the storm. It is better to break the boat, disclose all the information, and let everyone find the perverted killer together.

"But, this is all your reasoning...Let me speak out, isn't this..." Zhuang Yi was still hesitating. He felt like a poor student and suddenly got a test paper with full marks.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 was not relieved to do so, because after all, it relied on the analysis of others.

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

Lu Siyu has never been seeking utilitarianism. At first, he just hoped to correct his own thoughts. But now, the correctness of his thoughts is not important anymore. He seems to have been infected by Song Wen...

In the past, he seemed to be a lone ghost and wild ghost in this world. He lived awkwardly, unmoved by life and death, and lived for only one purpose, but after being with Song Wen, he began to care a little bit and began to look towards Those ordinary people.He suddenly became interested in this criminal police game. With the accumulation of case by case, he was aroused to win and lose, and he wanted to win more and more, and wanted to save more people as a policeman.

He wanted to catch the murderer.

At present, the murderer thinks that killing four people in a row should be the most proud and inflated time.It's like a balloon that has been inflated to its limit. It only needs a needle to reveal his true shape.

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

To untie the bell, you must tie the bell. Zhuang Yi has already attracted the attention of the murderer. If he gives a correct profile, the shock to the murderer will be much greater.

Lu Siyu doesn't care how Zhuang Yi will survive his crisis or whether he will be ruined.But he thinks he needs 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 pull that person out of tens of thousands.

After listening to Lu Siyu's words, Zhuang Yi pursed his lips. Song Wen saw his last hesitation and said: "Today's conversation, only the three of us know."

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

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

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