At the case seminar, Zeng Jinling, on behalf of the special investigation team, made a statement on the "dual personality": Dual personality is a type of multiple personality and is a serious psychological disorder. The American Psychiatric Dictionary defines multiple personality as "a person who has two or more subpersonalities that are relatively unique and separate from each other." is a hysterical dissociative psychological disorder "The basic characteristic of multiple personalities is that although the same person has two or more completely different personalities, at a given time, only one of them manifests.

Multiple personalities can have dual personalities, triple, quadruple ...... So far, the maximum can reach 24 personalities. Among them, dual personalities are relatively common, usually one of them is dominant, but both personalities do not enter the memory of the other, and they are almost unaware of the existence of the other. The transition from one personality to another, which usually begins abruptly and is closely related to a traumatic event; After that, switching usually occurs only when a large or stressful event is encountered, or when treatment such as relaxation, hypnosis, or venting is received.

"That means the killer may have been mentally ill?" Lu Bin was first surprised, and then indignant, "Isn't that impossible to investigate his criminal responsibility?" ”

"What are you excited about?" Fu Yiming snorted, "There is no evidence at all, how can you easily draw conclusions......"

The second half of his words were stuck in his mouth, because Li Haoxun, deputy director of the Public Security Bureau in charge of the criminal police detachment, walked into the conference room.

"Bureau Lee." Fu Yiming behaved very respectfully.

"Go ahead." Li Haoxun smiled kindly and walked to Wei Chihong and sat down, and whispered something to him.

Wei Chihong's gaze subconsciously cast in the direction where Qiao Yan was. The eyes of the two met, and Qiao Yan suddenly felt an inexplicable shock in her heart, and she couldn't help but quietly lower her eyelashes.

"Qiao Yan, report the results of the analysis just now." As soon as Wei Chihong said this, he himself was stunned, why did he call Qiao Yan? Obviously, it was Zeng Jinling who made the report just now.

All eyes in the conference room were focused on Qiao Yan, Qiao Yan felt a suffocating tension, her lips were dry, her heart was racing, and her brain was completely messed up.

"Qiao Yan." Li Haoxun also called her name.

Qiao Yan stood up nervously and crampedly, her gaze flashed from Yu Chihong's face and fell on Li Haoxun's face with a kind smile. Under Li Haoxun's encouraging gaze, her heartbeat slowed down, and after taking a deep breath, she began to report in as smooth a tone as possible.

The room was silent, and only Qiao Yan's crisp and pleasant voice led everyone into the inner world of criminals. Finally, she made it clear that not all persons with multiple personalities could be classified as mentally ill, and in fact only those with extremely severe split personality were classified as mentally ill persons with no or limited capacity for responsibility under criminal law.

During Qiao Yan's speech, Li Haoxun nodded from time to time, obviously agreeing. Fu Yiming didn't say anything back, just didn't speak with a gloomy face.

"Why do you have a dual personality?" Lu Bin humbly asked for advice.

"The reasons for the formation of a person's psychological problems are very complex, and the dual personality is more due to the interaction between the environment and the things experienced, plus the characteristics of one's own personality. For example, setting the goal too high but unable to achieve it, too much pressure leads to low self-esteem, escapism, fantasy that if you were another person, you will not have so much troubles and pressure, and gradually embark on the road of escape, but you can't forget your past, and slowly begin to don't want to choose, and the ideal self and the real self alternately. ”

Qiao Yan analyzed that from the case of the murder of the street girl, according to the analysis of psychodynamic theory, the prisoner may not have been effectively released from sex in real life, so the desire to commit the crime was stimulated, and the target of the crime was directed at the marginal group of "prostitutes" and sexually abused them. At the same time, he boiled the victim's kidney, presumably to eat it, to release his excessive backlog of instinctive needs.

However, the concepts that have been formed since childhood have a restraining effect on him, and after committing a crime, he returns to his true self, and after seeing the tragic condition of the deceased, he is very panicked and frightened, and of course it is impossible to eat the kidney. He held the corpse and shook and wept, and covered the deceased with a blanket. The prisoner is honest on the surface and abides by his duty, but deep down he is full of sexual desire and has a strong tendency to sexual aggression. This desire, as long as there is an inducement, will burst out in a twisted way. Catch this person as soon as possible, or he will commit more crimes. ”

"But Fang Hong was not sexually assaulted, isn't it strange." Lu Bin continued to express his doubts.

"Prisoners have sexual dysfunction that leads to perverted psychology that degrades, humiliates and subjugates victims by sexually abusing them, destroying their bodies, and even eating their organs." Wei Chihong answered this question instead of Qiao Yan, "Regarding the prisoner, there is still an important situation that needs to be explained. ”

A picture appeared on the LED screen, which was the traces of bruises on the corpse, which Qiao Yan had asked Li Shuhua before.

"Let's take a look at the bruises on the corpse." Yu Chihong clicked to open the next picture again, "The following one is a photo of the condition of the body when the deceased was found, the body was lying flat on the ground, covered with a blanket. Now going back to the previous picture, the bruise was on the left side of the deceased's body.

If the deceased had remained in a lying position after being killed, the bruises should not have been like this. This only means that the deceased was stuffed somewhere. ”

Everyone else present looked at the big screen in surprise, waiting for Yu Chihong to continue.

"The appraisal results from Cao Chongshan's side have also come out." Wei Chihong changed a photo, which was a footprint on the dirt floor, "A deep footprint was found on the dirt floor in front of the rental house where the deceased Fang Hong lived, and after comparing it with the footprints and soil in the rental house, it can be determined that it was left by the same person." However, this footprint is very strange, and it is speculated that the prisoner weighed 140 kilograms. ”

The scene was full of exclamations.

"140 kilograms?" Lu Bin exaggeratedly shouted, "How tall and strong does that have to be, even taller than Yao Ming." ”

Wei Chihong denied this speculation. "Judging by the size of the shoes, the prisoner is not that tall."

"Did you take something very heavy?" Qiao Yan couldn't help but interject.

"Exactly." Wei Chihong nodded approvingly to Qiao Yan, "In other words, the crime scene was not in the rental house where Fang Hong lived. After killing Fang Hong, the prisoner put the body in the trunk, then transported it to the rental house, removed the body from the trunk, and carried it back to the rental house. ”

"To drive your car in front of the rental house, you have to go through a nearby intersection with surveillance cameras." A police officer who attended the meeting provided important information, "As long as the surveillance video is called up, the vehicle can be investigated." ”

Fang Hong's presumed death was between 3 a.m. and 5 a.m., and the body was found at 8 a.m. The body was found by the landlord who had come to collect the rent, and after investigation, the landlord's suspicion has been ruled out. Wei Chihongyu was assigned the task of collecting surveillance footage from 3 a.m. to 8 a.m. that day to view all the vehicles captured by surveillance cameras. Other officers have also continued their investigations.

After the meeting was adjourned, Li Haoxun and Wei Chihong remained in the conference room. "The women's army of the special investigation team is getting better." Li Haoxun smiled with relief, "I'm very optimistic about them." ”

"That's good." Wei Chihong's evaluation of just three words is heavy.

Zeng Jinling left in a hurry with something to do, and Wanxing was still not very gregarious. Only Qiao Yan and Mo Yuqing went to the cafeteria for lunch together, and when they returned to the office, there was still a period of time before work, Qiao Yan brewed two cups of coffee, and chatted with Mo Yuqing while drinking coffee.

"The Hai Haoyi I saw at your house last time, did he still contact you?" Qiao Yan pretended to ask casually. Wei Chihong didn't bring up the temptation again, but Qiao Yan herself was very worried.

"No," Mo Yuqing blinked, "You seem to be very interested in that Mr. Hai, shouldn't you have taken a fancy to him?" ”

"How is that possible?" Qiao Yan thought it was funny, "I'm just curious, last time you said that there was a case related to his uncle, I want to know what's going on." ”

Mo Yuqing suddenly became sad. "The outcome of that case is so sad. Hai Haoyi's uncle did a lot of evil, and he deserved it, but this incident also involved our former detachment leader. ”

Qiao Yan's eyes widened. She didn't know anything about the former detachment leader, and she didn't expect to be involved in the case. ”

Mo Yuqing sighed heavily. "I'll cut it short. Hai Haoyi's uncle is called Hai Botian, the chairman of the original Haisheng Group, he secretly engaged in drug crimes, and also colluded with gangsters, killing many people. The former detachment leader was named Xin Zihua, and he used to be a very good criminal policeman. However, as Hai Botian's crimes were gradually exposed, his accomplice identity also surfaced. He was abused by his parents as a child, scarred, and in his most painful time, he met Hai Botian. Hai Botian admired him, cultivated him, and used him to work for himself. In the end, he and Hai Botian died together. ”

Qiao Yan roughly understood what happened, and she said with feeling: "The formation of a person's temperament, gender, morality, character, ideals, and sentiments all start from childhood, and they are all related to the education of his parents and the influence of the family environment since he was a child. ”

"Therefore, the tragedy of Captain Xin is ultimately caused by his parents, and his parents are the ones who are the most guilty." Mo Yuqing looked a little excited, and tears glistened to her eyes, "After I arrived at the Public Security Bureau, I became Captain Xin's assistant, and I admired his intelligence very much, until now, I still have difficulty accepting such a fact. ”
