"The victims were young women in their 20s, and they reminded him of his childhood games." A blurry image gradually became clear in Qiao Yan's mind, "The murderer regarded the victim as his mother......"

"How is this possible?" Wan Xing immediately interrupted, "The murderer raped the victim, will he rape his mother?" ”

Zeng Jinling said that such a possibility exists. This prisoner has a strong mother-love complex. The "Oedipus complex", also known as the "Oedipus complex", is one of Freud's theories of young children's sexuality. Oedipus is a character from ancient Greek mythology who killed his father in order to marry his mother. Freund used this term to express the boy's attachment to his mother, that is, the boy's first choice of love is often his mother, and he hates his father because of it. The mother-love complex is one of the main manifestations of children's sexual desire, and it is an inevitable manifestation after children's "narcissism". Children must get rid of the mother-love complex in order for their personality to develop or be healthy, and vice versa, they may cause sexual perversion. Freund believes that one of the causes of certain mental or sexual abnormalities in adults is the inability to get rid of the mother-love complex.

"The prisoner also had a fetish, not only did he like to collect women's clothes, but he also cut off the breasts of the female deceased, which is also related to the mother-love complex." Qiao Yan analyzed that "fetish" is a kind of sexual perversion, and the object of sexual desire of patients with this disorder is not the whole person of the opposite sex but a part of the body of the opposite sex, or the inanimate objects used by the opposite sex. Loving these things is not necessarily pathological, but only when these "fetishes" are detached from the loved one, they themselves become the object of infatuation and can arouse intense sexual arousal, and they become the object of desire relief.

The causes of such disorders are complex, and are mostly related to personal upbringing, family, socio-cultural environment, stress, and improper sex education. In infancy, that is, at the age of 3-5 years, boys often have a "mother-love complex", that is, it is manifested as attachment to the mother and rejection of the father, and during this period, if the mother is very doting on the boy and is very strong in the family, and often reprimands the child's father in front of the child, then it may lead to the "solidification of the mother-love complex", which is manifested as the boy's inability to identify with his father. In addition, if the mother sleeps in the same bed with the boy during this period, it is easy to increase the negative sexual stimulation of the child. And if the mother dresses casually in front of the child, especially walking around indoors in underwear, it is easy to let sexual stimulation enter the child's subconscious.

Qiao Yan and Zeng Jinling came to the same conclusion: the murderer regarded the victim as his mother at first, but the victim's fear, crying, and resistance made the murderer realize that it was not his mother. After being rejected, the murderer immediately felt as if he had been rejected by his own mother. Enraged, he raped the victim and killed her with a knife. He stabbed many times, showing his strong hatred. The killer was separated from his mother when he was a child and was rejected by her. The film recreates the scene when his mother changed into beautiful clothes and posed in front of him, which he regarded as a beautiful game. This is the delusion of the murderer.

Zeng Jinling handed over the task of reporting the results of the criminal portrait analysis to Wei Chihong to Qiao Yan.

Wei Chihong sat on the sofa in the detachment leader's office, the sofa was facing the corridor at the door, and people had to pass in front of him. He would often open the door of his office, sit on the sofa, and think about problems while monitoring the hallway and the two offices of the First and Second Brigades opposite. As soon as the wind blows, it can't escape his eyes. After his subordinates slowly figured out his habits, they were all cautious in their words and deeds, and did not dare to make any small moves.

As soon as Qiao Yan arrived at the door of the office, she saw Wei Chihong get up and walk and stand still in front of her.

"Got a result?" His tone was calm, but his momentum was overwhelming.

Qiao Yan nodded and explained the conclusion. "There's only one question left unanswered. That's why only the fourth corpse is intact, and what exactly is the use of the silicone left on the breast. I'll come back to the school later, and maybe I'll find something new. ”

"I'll go with you." Wei Chihong immediately made a decision, "The case seminar will be held at 11 o'clock in the morning, and it is only early 8 o'clock now, and there are still three hours, which should be enough." ”

It is only about 20 minutes' drive from the Public Security Bureau to the Vinci Art Academy. During class time, most of the students went to class, and it was quiet around the girls' dormitory. Men can't enter, now is not a serious investigation, Wei Chihong didn't want to use his identity to make something special, so he asked Qiao Yan to register alone to enter the big iron gate of the girls' dormitory complex, and the two acted separately.

Wei Chihong stood in front of the big iron gate and looked around, the construction site next to the container coffee shop was still under construction, and the coffee shop was open as usual. There is a school building at the back of the site, which is about 60 meters away from the wall of the girls' dormitory complex and about the same height as several girls' dormitory buildings. The school buildings are scattered, and there is only one teaching building in this area, and there are no other buildings except for the low canteen and the new building that is still laying the foundation.
