The sunlight outside the window is always bright and sometimes dark, and the wind is passing by, and the fresh green leaves sway, only making small sounds that interact with the wind.
After listening to Professor Sun's analysis, Huo Xiaofang and Zhu Yu sank for a while. Huo Xiaofang: "If the murderer is the same person ten years ago, why would he take another shot after ten years?"
Professor Sun frowned, "According to what you said, the murderer did not physically abuse the victim. He even deliberately left clues on the scene and returned to the scene again to leave clues.
The murderer had a very contradictory existence in his heart. He felt that the victims had a miserable fate. He helped them completely get rid of this pain. He also felt a pity for their deaths. He hoped to give them some justice, but he did not want to be taken by the police Ferret out. So while killing people, he destroys clues and leaves clues at the same time.
As for the ten-year interval, it is possible that he has been stimulated by some kind of life in the recent period, which has made his hidden personality reawaken again. "
Zhu Yu and Huo Xiaofang were dumbfounded for a few seconds. Zhu Yu raised his eyebrows and slapped his legs: "This is too fucking perverted!"
Huo Xiaofang: "From this point of view, in the suicide case ten years ago, there was no clue to the murderer at the scene. However, in the two cases that occurred now, he deliberately left clues. Does it mean that he is currently mentally ill? Is it greater than ten years ago?"
Professor Sun nodded: "Yes, in the process of leaving you with clues, he gained a sense of psychological satisfaction, and such a sense of satisfaction just compensates for the negative impact he has caused by the underlying morality after killing the victim. Guilt."
Zhu Yu: "A place like Shicheng has such a perverted existence."
Professor Sun: "The murderer is obviously highly educated and has a careful thinking. You have to investigate this time. I am afraid that you will be extremely energetic. You must not ignore every small detail. Otherwise, even if he leaves clues to you, he will be As it was ten years ago, the case has not been solved. This will further encourage his pathological arrogance, fearing that he will completely fall into the pleasure of murder and more people will be victimized."
Huo Xiaofang: "Highly educated?" He glanced at Zhu Yu: "Brother Yu!"
Zhu Yu: "Immediately ask Zhou Zhen to go to the Information Bureau to check the list of Shicheng's highly educated talents." Professor Sun: "Since he dared to return to the scene to leave clues, it shows that he has a large degree of understanding of your actions, or It is said that when he commits the crime, he can already predict your next actions, and the time for the clues you find may be in his prediction. Also because of your actions, he has already made a prior judgment, Later, when it was confirmed that your progress was consistent with his prediction, he began to feel conceited."
Zhu Yu: "The more conceited he is, the easier it is to make mistakes, and the more likely it is that we can find out his identity faster and catch him into the net."
Professor Sun gave him an agreeable look: "Yes, when you are satisfied and satisfied, your mental state will relax. Once you relax, the clues will be revealed. So you must pay more attention to the details."
Huo Xiaofang's gaze swept across the bookshelf, and a group photo entered his eyes.
Zhu Yu followed his gaze and looked over: "Professor has this photo been a few years old?"
Professor Sun turned his chair, stood up and took the photo frame: "It's more than ten years ago. This was my first psychology class at that time, and I took a photo after class as a souvenir."
