There was a lot of discussion at the scene, and most people felt that Qiao Yan's analysis was very reasonable.

"The murderer initially took away the murdered women, not with the purpose of killing, but because they were rejected, they were embarrassed and angry and killed." Qiao Yan continued, "The murderer sent the film to the Organizing Committee of the College Student Micro Film Festival, the reason should be that he and his mother went to watch a movie together, and the movie theater is a place full of good memories for him, and the memories of being with his mother are deeply engraved in his heart. He wants to be in the cinema, watching works reminiscing about his mother, and relive the good feeling of childhood. Therefore, knowing that there were police watching, he still went to the cinema and tried to take Mo Yuqing away. ”

"On what basis is it determined that the prisoner is between the ages of 27 and 29?" Fu Yiming still has a distrustful attitude.

Qiao Yan answered: "This specific method of murder is not formed overnight, most of the murderer's paranoid delusions are born at the age of 19, and there is still a 'gestation period' of about 10 years. The reason why the killer is believed to be under the age of 30 is because no similar incident has been found in the vicinity. ”

Fu Yiming had nothing to say.

Wei Chihong looked around the audience. "Any questions?"

No one raised any further objections.

"Then act immediately and arrest the prisoners." Yu Chihong's demeanor was majestic and solemn, "The scope is locked in the sculpture department of the Leonardo da Vinci Art Academy." ”

"Why does it have to be the Department of Sculpture?" Others expressed doubts.

"There are three reasons for this. First, people in the sculpture department had access to silicone and were most likely to make models of the deceased's breasts; Second, the Department of Sculpture and the Department of Art and Design are in the same building, and the prisoners have the opportunity to come into contact with Lin Fang and Wei Yishan; Thirdly, from the window of the sculpture studio, the entire women's dormitory area can be observed, where the prisoners must have been under surveillance. Wei Chihong was completely sure, "The prisoner is already under our control!" ”

Inspired by the portrait of the criminal mind, and the accurate demarcation of the scope, the serious crime team was dispatched urgently and quickly arrested the murderer. The murderer's age, appearance, experience, etc., are exactly consistent with the description of the portrait - Zhang Ping, 28 years old this year, is a graduate student in the sculpture department of the Leonardo da Vinci School of Art. After graduating with a bachelor's degree in fine arts from another comprehensive university in the city, Zhang Ping became a professional sculptor, and a few years later was admitted to the Leonardo da Vinci School of Art and returned to school for graduate studies. He belongs to a family with a house and a car, and his economic conditions are superior.

The criminal police locked Zhang Ping through investigation and found his residence outside the school. When the criminal police broke into the door, Zhang Ping was holding a sharp knife in his hand, wanting to poison Wei Yishan. Wei Yishan was unclothed, crying in horror, and was on the verge of a nervous breakdown. The criminal police successfully rescued Wei Yishan.

During the interrogation of Zhang Ping, Qiao Yan and Wei Chihong stood in front of the single-phase perspective glass in the next room, quietly watching the scene in the interrogation room.

Zhang Ping is of medium stature and handsome. He was evaluated by his teachers as an excellent student and was an approachable brother in the eyes of his classmates. No one would associate him with the terrible word "murderer".

From his calm narrative, the roots of his crime can be traced: Zhang Ping has a strong mother who always scolds his father in front of him. But his mother loved him very much, and she was obedient and doting. At a very young age, he developed a strong sense of disgust for his father, and was overly attached to his mother, and when he was 8 years old, his mother still held him to pee. He can't sleep without touching his mother's breasts, and he grew up with his mother's nipples.

Recalling the good times when he watched movies with his mother as a child, Zhang Ping's eyes showed a hint of innocence, but soon his eyes became gloomy, stubborn and weird. "She didn't want me anymore, so she left like that, and never came back!"

When Zhang Ping was 8 years old, his mother divorced his father and followed another man. After his mother left, he found a pair of shoes that his mother had discarded, beautiful red heels, from the dumpster, which he carefully collected, and since then he has become obsessed with women's clothing.

During his studies at the Leonardo da Vinci School of Art, Zhang Ping was very appreciated by his graduate tutors, and often participated in the creation of sculpture studios. One night, he saw the clothes hanging in the girls' dormitory from the window, and the desire that had been buried in his heart for many years was suddenly hooked, and he began to peek at those brightly colored and beautiful clothes with a telescope.

One day he finally couldn't help it, and went to the outside of the girls' dormitory complex, when the management of the girls' dormitory was not so strict, he thought about how to get in, and met the first victim by chance, he was stunned, the victim's appearance, very much like his mother.

Evil thoughts arose in an instant, and he went up to talk to her, and under the pretext of looking for a model, he smoothly got the girl into his car and out of school.

What happened afterwards was that the victim was killed because of her resistance, as described in the psychological portrait. "I love her breasts, they feel like my mother's, and I want to touch her breasts to sleep, so I cut them off." A sickly smile appeared on Zhang Ping's pale face.
