Three days later, experts from the Criminal Psychology Research Department of the Provincial Bureau sent a report on the portrait of the murderer.

Since May, three students of Nanzhou Drama University have died one after another, and after multiple analyses by the police, it can basically be determined that it was committed by one person. So far, the people of Nanju have been in a state of panic, basic teaching activities have been seriously hindered, and all kinds of rumors have been flying all over the sky, and the situation has reached the point where there is no room for delay.

Old experts in criminal psychology believe that the murderer is hiding in the campus of Nanqu, or is extremely familiar with the campus environment, and is between 20 and 25 years old. He is a sturdy man, at least 175 cm tall, with unknown facial and postural features, and is right-handed.

Because the murderer's anti-reconnaissance ability is very good, the analysis of his physiological attributes is relatively vague. It is likely that the murderer usually likes to read detective novels, or has a perverted hobby of controlling other people's lives.

Criminal psychologists recommend focusing the investigation on the mental portrait of the murderer. Judging from the three cases that have occurred, the psychological characteristics of the murderer are intriguing.

First of all, from the perspective of social relationships, the murderer is unmarried and lives with his parents, but the relationship is not good. The place of residence is messy, the environment is dirty, and it is at the bottom of society.

This can be seen from the murderer's previous criminal behavior. Every time he committed a crime, he strangled the victim with simple tools (hemp rope, seat belt), or directly used stage props to cause accidents, and there was no overly complicated scene, indicating that the murderer did not have the time or energy to carry out a lot of preparatory activities.

Because of the urgency of family relations, he will most likely have no extra money and prepare with great fanfare to be found out by the people who live with him (parents, siblings, etc.). His family is short-tempered, old-fashioned, selfish, and uneducated, and will not persuade and comfort him, and will use more vicious language to make him even more aggrieved. All the anger and grievances must be borne by him alone.

In addition, every time the murderer commits a crime, he can quickly disappear, indicating that the murderer is extremely familiar with the campus environment of Nanqu Opera and the people on campus, and it is very likely that he is an acquaintance who gets along with the victim day and night.

The murderer had a high level of education and had a certain degree of cultivation in electrician and physics. I don't pay much attention to social dynamics, and I don't like to go out for parties and travel, but I pay great attention to every move that happens on the campus of Southern Opera, and even have special sensitivity to certain sectors. In life, he doesn't have many friends, he is easy-going and dull, but he has a strong sense of self-esteem. If someone offends him, he will retaliate in his own and extremely vicious way.

There is a pathological tendency in the psychological state of the murderer. In the opinion of criminal psychology experts, the psychological quality of the murderer is not good, at least after each killing, he will have regret and self-blame, but this process is extremely short. When he returns to his own life, the momentary self-blame is quickly dissipated by the heavy tragedy of life, and he will once again feel that what he did was right.

According to the analysis in the report, the unstable mentality of the murderer confirms that the murderer is not very old, and his psychological distortion is likely to come from the tragic experience of his family. It is very likely that the murderer lives in a single-parent family, or his parents are not at odds, and there is domestic violence, and his family has brought him unforgettable harm.

In his past life, the family did not bring him the slightest sense of belonging and happiness, but only like a heavy shackle, suppressing his temperament, brewing his hatred, and every time he recalled, he would be brought back into the abyss of no return.

The damage caused by his family is likely to be related to love. This can be seen from the common characteristics of the three victims. Bao Fei is obsessed with boys, regards boys as his prey objects, and even does not hesitate to make a fight with his classmates in the cafeteria; Han Yongyi and wealthy businessman Fu Xueqian have an improper relationship between men and women, and regard the love between men and women as a transaction; And Zhang Kefan was caught in the girl's clothes turmoil before the incident, this person loves to collect girls' clothes, and he also likes to watch yellow discs in the middle of the night.

Without exception, all three of them did something related to love, unintentionally or intentionally came into contact with the murderer, and touched the sensitive area of pain in the murderer's heart. The trauma of the past was ruthlessly uncovered again, greatly deepening his sense of frustration, so that anger finally exploded inexorably.

It is also possible that the above three people did not have direct contact with the killer. But their ambiguous behavior made the murderer touch the scene, like a fuse to ignite the anger accumulated in the murderer's heart, thus becoming a "scapegoat" in the murderer's eyes. At this time, the revenge is extensive, and the side reflects that the murderer's growth background is extremely dark.

The murderer is sensitive, suspicious, dependent, and has weak self-control, and the already vague concept of good and evil has almost disappeared in the feeling of killing people again and again. Emotions are easily aggressive, usually act too much, and are prone to indecision.

Women accounted for two of the three cases, but none of them were sexually deviant. Therefore, it can be assumed that the murderer has a certain prejudice against women, frigidity or sexual loathing, which has a lot to do with his previous experience of frustration. It is very likely that the female members of the family, such as the sister or mother, misbehaved, and witnessed a dark scene when the murderer was a child, which led to today's personality disorder.

The murderer initially hesitated on the edge of good and evil, and after several killings, he experienced the feeling of controlling life and death, and the modus operandi escalated destructively. The dissolution of life under his hands can make him experience a feeling of contentment and make up for the previous frustration.

He began to pursue more and more sensational modus operandi, from carefully strangling people in the auditorium in the middle of the night, to committing crimes in a BMW car lurking, and then to publicly hanging himself in front of thousands of people's attention, killing the person who violated him, which has become a tool for him to realize his self-worth. If this person does not obey the law, he will definitely commit the next crime.

In daily life, the murderer is a person who is psychologically cold, introverted, silent and alone, and does not want to deal with women. He often seems to be unable to wake up, his hair is casual, and his clothes are mostly dozens of dollars from a stall. However, the face may be relatively handsome, and it is easy to attract the attention of women.

The murderer's criminal process has hidden marking behaviors, that is, he has his own set of relatively fixed criminal behavior patterns. All three victims died of suffocation from neck compression, and the killer did not insult the corpses. From this point of view, the murderer is mentally sound, can take into account the causes and consequences of the killing, and has had a short regret afterwards, but the primitive desire in his heart still encourages him to commit murder again and again.

The so-called marking behavior refers to a special type of behavior carried out by the perpetrator in order to satisfy the psychological or emotional needs. From well-documented, plotting revenge and so on.

At the end of the report, the criminal psychologist suggested that the police should not stick to the campus, but walk around some economically backward places in the surrounding area, which may have unexpected gains. Now that the murderer has dropped the ring, the fox's tail has been exposed, and it is believed that he will be arrested and brought to justice.

Xing Song finished reading the portrait report and sighed often. The Chanel ring in the evidence bag sparkled in the sunlight, and according to Li Youyi's confession, it fell out of Zhou Yanchen's pocket.

Although the chain of evidence has not yet been formed, the suspect has emerged.

But is that beloved and handsome school grass really a murderer?

If so, his family must have suffered some indelible blow.

Xing Song found the principal of Nanqu, logged in to the school's Office of Student Affairs, and asked for Zhou Yanchen's home address. It is: No. 505, Dinker Street, Huang'an District, Nanzhou City.
