It was nearly two in the morning, and the police officers were still busy outside the police car.
Inside the police car, Lu Siyu continued to analyze: "Most of the dual personalities and personality switching are uncontrollable. Only with the appearance of stressors, will a fixed transition occur."
As Lu Siyu spoke, he put his fingers together, placed his chin in front of the sharpened chin, and continued: "The killer's stressor should be sex, because violence can no longer satisfy his inner desire, so at this time the second personality Appeared. Although the murderer had sperm spots in the case, there was no direct intrusion. The forensic doctor also deduced 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 needs it urgently, a personality transformation will occur."
Song Wen frowned and listened: "So 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 violent, he has a simple mind, developed limbs, and finally a conscience. He may seem honest and taciturn. Once stimulated, he will have violent tendencies. The other personality is an epigenetic personality, and this personality is extremely perverted. , very calm, wiser and more ruthless than the main character..."
Lu Siyu deliberately slowed down his speech to allow Zhuang Yi to digest these inferences: "The murderer may have encountered some twists and turns when he was young, and his childhood experiences made him confused and distorted about women, makeup, maternal love, and sex. The resulting sub-personality, in the self-characterization, sees himself as a calm, confident and elegant person, and finally manifests as a special criminal mode with a signature... ”
Hearing this, Zhuang Yi nodded and murmured: "So the murderer of the 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 this may be related to the murderer's personal experience. This behavior misleads you." , but it made Lu Siyu's thinking clearer.
"The violent personality is like strong limbs, and the perverted personality is like a calm brain. Both personalities want to occupy the body, but it is obvious that the perverted personality is gradually gaining the upper hand. He appears more and more times, 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 the time when the perverted personality appears. I noticed that today's young girls are not seriously injured, it is very possible, This murder was planned from beginning to end by the perverted personality, and the violent personality may not have appeared."
Song Wen often listens to Lu Siyu to analyze these, and has long been accustomed to his extraordinary intelligence. His voice was calm and indifferent, 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 seems to emit light, and there is a magic power that makes people surrender.
"I can think of this, but Team Song reminded me." When Lu Siyu said this, he looked up at Song Wen.
Song Wen asked: "Did I bring up the possibility of dual personalities in the last meeting that inspired you?"
Lu Siyu looked at him with good-looking eyes: "Not only that, you pointed out one point before, in the first case we came across, there were obviously many more marks on Li Ling's neck than in other cases. Caused. I only figured it out today. It was because the murderer stimulated the sub-personality after receiving the stimulus, and in the process of personality transformation, cognitive confusion appeared. That is to say, in the process of that murder, the two personalities were confused. 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 had crossed each other, and the further he developed, the more dominant his perverted personality was, and the more he began to occupy the body. initiative.
Lu Siyu paused for a few seconds and concluded, "Most people with split personalities or multiple personalities have imperfect childhoods, and his abnormal personality should have formed long ago. I don't know what stimulated him, maybe it started from the first case, or maybe earlier, his perverted 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? Why did he put makeup on the victim?"
"The murderer has hatred for women, which can be seen from many violent injuries. But he is very proficient in makeup. I think this comes from his self-knowledge." Lu Siyu continued to analyze.
"The murderer may have a natural dysfunction, so he is not the same as a normal person since he was a child. He may have lost his mother at a young age. Make-up is a gender inversion. He is reminiscing about his mother and reflecting on himself at the same time. He doesn't think of himself as a complete man and wants to be a woman, that is, to escape reality by being a woman. He sees makeup as a sacred and romantic step, like the process of a caterpillar turning into a butterfly and spreading its wings. "
"Make-up is a means for the victim to achieve the perfect woman in the murderer's mind. In the process, he wants the woman to be alive and quiet enough. In the dark night, with the lights on, he paints the woman's face carefully. Then he The strangulation begins, the woman wakes up, struggles, and he gets the ultimate satisfaction. He's using this process to replace the physical needs."
So far, all the details and processes in the case have been analyzed by Lu Siyu. Some of them are inferred, some have not been proven, 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 hand on his trousers and clenched it into a fist. This small gesture did not escape Lu Siyu's eyes.
The person in front of him was hesitating, and Lu Siyu continued: "I think 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 the profile is closer to the murderer.
Song Wen had been listening to them just now. At this time, he looked at Lu Siyu. He had some idea of what Lu Siyu wanted to do.
Sure enough, Lu Siyu said, "Professor Zhuang, if most of what I say now is confirmed, I hope you can go to 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 and release all the information, so that everyone can come together to find this perverted killer.
"But, this is all your reasoning... Let me say it, isn't it..." Zhuang Yi was still hesitating, he felt like a poor student, and suddenly got a perfect test paper. Right now, he really needs such a beautiful answer sheet, and if this answer is correct, it may even become his life-saving straw. But he is not at ease doing this, because after all, it relies 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 Ye Xiao and Ye Die names are quite appropriate when you turn them around and put them on. ."
Lu Siyu has never sought utilitarianism. At first, he just hoped to correct his thoughts, but now, the correctness of his thoughts is no longer important, he seems to have been infected by Song Wen...
In the past, he seemed to be a lone ghost in this world, living in a turbulent life, not accustomed to life and death, and only lived for one purpose, but after being by Song Wen's side, he began to care a little bit, and began to look at him. those ordinary people. He suddenly became interested in this detective game. With the accumulation of cases one by one, he was aroused by the desire to win, 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 believes that he has killed four people in a row, which should be the most proud and most inflated time. Like a balloon inflated to its limit, it only takes a needle to reveal his true form.
The murderer will soon learn that the fourth girl is not dead. At that time, he would become furious.
It is necessary to tie the bell to untie the bell. Zhuang Yi has already attracted the attention of the murderer before, and if he gives a correct profile, it will be much more shocking to the murderer.
Lu Siyu didn't care how Zhuang Yi would get through his crisis and whether he would be ruined. But he thinks that he needs to use Zhuang Yi's influence to attract more attention, destroy the confidence of the murderer, and let him show his feet.
If the profiling is accurate, they can even pick that person out of thousands of people.
After listening to Lu Siyu's words, Zhuang Yi pursed his lips. Song Wen saw his last hesitation and said, "Only the three of us know about this conversation today."
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, and 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 turns out that there is no problem, I can do it."
