Interrogation room.

The expression on Lou Sanfeng's face has not changed at all. It is almost the same as when he was taken out by the Water Affairs Bureau yesterday. This kind of indifference cannot be achieved by ordinary people.

Xu Dayuan was not discouraged. After all, he was caught, the evidence was conclusive, and everything was a matter of time. He calmly grabbed a stack of photos, walked up to Lou Sanfeng, and placed the photos one by one in front of Lou Sanfeng.

"This is a real estate on the South Island of Shahekou. The owner of the property and land is Yu Xiulian. According to our investigation, Yu Xiulian is your father's mistress and also Chen Gang's mother. I don't know why she didn't marry her back then. She married abroad, but Man had passed away in 2009.

Here, we found the DNA and fingerprints of the Zhu family of three in the 2004 kidnapping case in 4.14. We also found Fang Yue's fingernail in the beading of the aluminum alloy door on the north side. There was blood on the nail, and the DNA was quite well preserved. .

In the dark compartment on the ground on the second floor, the murder weapon, the Triangular Army Stab, was found. In the garage, 890 million yuan in cash was found. Of course, more than 3 yuan was damaged due to mildew. Don’t worry, there are many photos. I will introduce them to you one by one.

As for this severed finger, it belonged to Cheng Xinghui, a survivor of the 2000 kidnapping case in 2.3. We used the most advanced extraction technology to find your DNA fragment and some traces of oil on it. This is a special product used on ships. lubricant and was discontinued in 2003.

About Chen Gang, as well as the various photos and pictures of Fang Yue that were stored with you, we have also found and found out. I think you have nothing to hide now. Tell us about the process. I would like to talk about the two cases first. Whichever is the first to say. "

Lou Sanfeng didn't speak, and still looked at Xu Dayuan calmly, without moving his eyes down, as if what Xu Dayuan said had nothing to do with him, which was beyond the level of calmness, indifference, indifference, fearlessness, and lack of interest .

Xu Dayuan was neither impatient nor discouraged, he pulled out a chair and sat opposite Lou Sanfeng.

"We researched the video of you in the room last night, and consulted relevant medical experts. You didn't sleep all night, you scratched the wall, tapped your toes, and repeated such actions endlessly. This is a typical obsessive-compulsive disorder.

I was a criminal police chief of the Qidong branch at that time, but our small team not only caught the murderer, but also found key evidence, which made him confess. That person was left at his grandfather's house by his parents since he was a child, and no one cares about him. grew up in a distorted environment.

Lou Sanfeng didn't speak, but he stopped pulling the handcuffs, raised his head, glanced at Xu Dayuan, and then smiled.

Although the other is a permanent residence, it’s just a residence. Except for clothes, you don’t have any important items. But what I don’t understand is why you keep so many medicines left over from your father’s medication in your car. Is it a souvenir? ?
I had someone test the ingredients of these medicines. It’s very interesting. Each medicine has nothing to do with the ingredients on the label. They are all vitamins. You changed your father’s medicine, right?Because he was forced to change jobs?Or what did he do to you? "

Zhou Ning, who was next door, stared at Lou Sanfeng, seeing that his right index finger was constantly picking at the handcuffs, and the skin on the part that was being picked was already reddened, and it was about to be torn.

He also talked with Li Chengbin about this point, and Li Chengbin also suggested that he list this as his research direction, but he didn't do so, he still took the time node of the autopsy process as his research direction, after all, this is what he should do of.

Lou Sanfeng was bewildered, and the room became quiet. After some time, Lou Sanfeng shook his head.

My family lives in Tongshan District, which is an ordinary two-bedroom apartment. "

If we use "chameleon" to understand multiple personalities, it may be more vivid and intuitive.For example, Lou Sanfeng uses a relatively moderate personality to cope with work in the unit; uses a cowardly and humble personality to win sympathy and dependence; uses a cold-blooded killing personality to kidnap and kill people.

"The sub-personalities of multiple personalities are independent and separate from each other. When one personality appears, the other personalities will automatically exit. At any time, one main personality is dominant, and human behavior is determined by the dominant personality." "on duty" and control, and there will be no "chaotic state in which several personalities compete for control".

Zhou Ning didn't stop him. In fact, this is a relatively typical case. There is no harm in experimenting. However, he has multiple personalities, and the various attitudes he expresses are all sincere. Whether he can judge it is hard to say.

From the things you kept in the box on the second floor, we found a lot of photos of Fang Yue, some posters and pictures, and even a group photo of your graduation. I think you liked Fang Yue when you were in elementary school, right?
Still, why kill her and her family?Could it be that seeing Fang Yue living such a happy life, and then looking at your life in a mess, do you want to drag her into a dirty quagmire?What you can't get, destroy her? "

"I don't know, I'm not in good health, and my mind often goes blank. Sometimes I don't know how to pass for a few days. As for Fang Yue, she is indeed my classmate, just my classmate. I don't know that she is dead. As for you I have never been to the house in question.

When you force yourself to repeat a certain action, your mind is not blank, but you are suppressing your urge to do something, especially when it is manifested in people with multiple personalities, most of them are suppressing the appearance of a certain personality.

"do not know."

Liu Yufei glanced at the phone, then got up and handed the phone to Xu Dayuan, Xu Dayuan glanced at it and nodded.

Liu Yongxin realized suddenly and slapped his thigh.

You remember that when Cui Guanglin was interrogated, he said in a panic at the end, please keep your voice down, don't let that Cui Guanglin hear, or he will come out to retaliate. "

"We checked your movement track for a month through the monitoring of the traffic police department. We went to the two properties under your name. One has the same style as the military camp, but the clothes inside are different from yours. So this is not where you live.

Staring at Lou Sanfeng, Xu Dayuan lit a cigarette, held a disposable paper cup with water at the bottom of it in one hand, and kept flicking ash into it, shaking his stiff neck, and then signaled Liu Yufei to put away all the photos. Only then did he speak.

Taking out his phone, Zhou Ning sent a message to Liu Yufei, briefly expressing his opinion and introducing multiple personalities. Of course, the final judgment was also explained, and he even wrote a sentence:

"I didn't kill people, I didn't kill people, I don't know what to say!"

"Then tell me, who killed the man?"

It’s just that the method you chose was wrong, and Chen Gang didn’t listen to your persuasion. He chose to let the baby live at the last moment. I don't understand Fang Yue's emotion.

In essence, multiple personality is a psychological phenomenon that adapts to the environment by frequently changing personalities. He knows what he has experienced so he is acting.

His parents and younger brother Chen Gang should be his weaknesses, and they can be induced in this direction. Even the deaths of the three of them are inseparable from him, and it is not too much to cheat.

Xu Dayuan also laughed, a reaction is the best encouragement, he is not in a hurry.

Erlang's legs are crossed, and there is a smile on his face. This smile makes people sweat.

So no matter what I say, you don’t care about it, even with a very wronged expression. These methods may be effective for your father, but they are useless for the police. I have told you so much, not because I want you to explain anything.

Lou Sanfeng shook his head.

After so many questions, Lou Sanfeng stared at Xu Dayuan, without the indifference before, he lowered his eyes and let out a breath.

Seeing Lou Sanfeng's reaction, Xu Dayuan was still happy. After talking for half an hour, if this person didn't respond again, he would also collapse.

Zhou Ning shook his head. Regarding this knowledge, during his study during this period of time, he focused on reading relevant materials. Those related research documents published after 2020 gave more detailed explanations.

On the outside, he is an excellent high school teacher with excellent teaching ability, good facial features, and a wealthy family, but secretly he has a distorted personality and cruel nature. Under the observation of the forensic doctor in our team, we found that this person has hidden extra personalities. Later, he confessed.

"We went to the property you mentioned, do you know why you were not interrogated yesterday?"

"I'll ask Xiaoqu to come here. The facilities here are well-equipped, so I might as well bring the software here for Lou Sanfeng to use."

What kind of personality is to be dominated, completely follow the principle of "which kind of personality is most suitable for the environment and needs at that time, which kind of personality will be activated and emerged".This is actually a psychological version of the law of survival of the fittest.

"Time flies. It's been more than a year since I was transferred to the Municipal Bureau. Do you know why I came to the Municipal Bureau? Since you don't want to say it, I'll just chat with you. As for the murder case, there were more than a dozen victims in six years, and the case alarmed the Ministry.

As soon as this sentence came out, Xu Dayuan fell silent, he couldn't tell, Lou Sanfeng was acting, but he really didn't remember.

"Apprentice, don't multiple personalities communicate with each other? Or, he chose to make this personality not remember everything that other personality did?"

I think part of his situation is very similar to yours, but there are also differences. When you followed the leader to meet Chen Gang, I think you really felt sorry for that half-brother. You wanted to help him out of trouble, even Don't go through what your childhood went through.

I still say the same thing, now all the evidence is very complete, not to mention the 2000 kidnapping case in 2.3, but just the 2004 April 4.14 kidnapping case, what is the route you chose?How does the client send the letter?
Manipulating Zhu Yantao to leave the Polar Aquarium, you have completely controlled his psychology. The person who is eager to save his son has lost his judgment, and the only thing left in his heart is guilt. Then you lead Zhu Yantao to Xiaofengtai, where the four Dropped a purse.

And you just waited below, packed all the bags, drove the motorboat straight to the South Island, no, it should be said to go straight to the direction of the South Island, because you have hidden the car in the hidden place of the scenic bay and discarded it The money bag was loaded and transported away by motorboat.

I have to say that your plan is quite perfect. With the technical means back then, it was really impossible to detect it, especially with the influence of external factors. You got the money, the mistress' real estate, and Fang Yue.
But you have no one to share, your father died, your brother died, your mother died, and they all died because of you, the cause you planted, you have to bear the fruit yourself, just like now, even if you want to Pretending to be mentally ill, but you have no family members to apply, tsk, what a pity! "

Lou Sanfeng grabbed the corner of the interrogation chair, and as Xu Dayuan spit out every word, his breathing became more dignified. In the end, his veins were exposed and his eyes were red.

"Shut up, you shut up!"
