crime profiler in the dark

Pages 1-3 introduce the basic situation of Zhuang Xumao: Zhuang Xumao was originally from City A. When he was four years old, when he and his mother went to visit his father in TMX City, the train derailed, causing his mother and more than 100 people on the same train to derail. Passengers died.Because Zhuang Xusubaru's father was busy with work and had no time to take care of him, he was entrusted to his grandparents to take care of him.

It was not until the age of 16 that his grandfather passed away and his grandmother moved into a nursing home. His father brought Zhuang Xumao to TMX City. until he went to college.

The fourth page is a newspaper clipping from the report on the train derailment incident that caused the death of Zhuang Xusubaru's mother 4 years ago. Bai Haolin couldn't help but admire Yi Yunzhao. In the era when there was no Internet search, he could find such an old newspaper.The newspaper clippings roughly wrote about the reasons for the derailment of the train and the handling of the person responsible, but Yi Yunzhao marked one of the lines with a highlighter: "The only survivor in carriage No. 19 was a 17-year-old boy. His mother died at the last moment. Protect him with your body..."

Pages 5-6 are the autopsy report of Zhuang Xuxuan's mother. Because the train derailment accident happened in city B between city A and TMX, the coroner is also the forensic doctor of the police station in city B. In the column of cause of death, he wrote : "A steel bar about 20 centimeters long pierced the carotid artery of the deceased, causing the artery to burst into blood. The cause of death was excessive blood loss."

At this time, Yi Yunzhao, who had been staring at Bai Haolin closely, saw that he had seen the autopsy report, and explained: "I asked Dr. Qin, and she said that the arterial burst of blood is similar to the blood spurt when the throat is cut, sometimes up to More than one meter away, if someone stood opposite him, it would be like raining blood."

Bai Haolin still remembers the profile he wrote about the No. 1 victim in the throat-cutting case when the murderer deliberately turned to face the glass of the sightseeing elevator: the murderer's subconscious made him want to admire the spout of blood staining the whole body from below. The feeling of the glass window is undoubtedly in line with Zhuang Xusubaru's childhood experience, but the question is, how did his mother die to protect him back then, how did it evolve into such a brutal killing method in the end?

Pages 7-10 are considered to be the answer to this question. This is what Yi Yunzhao learned from Zhuang Xumao's family after he found them. There are not many records of Zhuang's father's evaluation of his son, but he wrote a lot about his stepmother. According to the description from the neighbors, in their eyes, Zhuang's father was not good to Zhuang Xusubaru. He always blamed his mother's death on Zhuang Xusubaru, and often confronted each other violently, especially when he was drunk.

Zhuang's father's behavior brought greater psychological trauma to Zhuang Xusubaru-children who witnessed bloody scenes in childhood were prone to violence, coupled with his father's blame, Zhuang Xusubaru's view of his mother changed a lot. Big shift - in general, when kids lose their mothers, they usually see the mother as a victim and want to protect women, not hurt them.

But Zhuang Xumao's father was not by his side during his childhood, not only failed to make up for the trauma and shadow brought about by his mother's death, what was even worse was that he inflicted violence on him during his second rebellious period (that is, adolescence), which made Zhuang Xumao Views of the mother evolve from sympathy and guilt to anger and hatred—a bad emotion for her untimely death, which leads to a fascination with blood and disrespect for women.

Pages 11-14 are Zhuang Xumao’s sophomore year in high school. A third-year student was scolded by his teacher and became resentful. He brutally killed the teacher. The student’s parents hired the best lawyer in the city to defend him. I found a psychopathologist who proved that he has a paranoid personality and suffers from delusions of persecution, that is, the murderer thought that the victim would threaten his life before he acted first, so he did not have the ability to be criminally responsible and The ability of civil liability, the defense of the lawyer allowed him to escape the severe punishment of the law, and he was only sentenced to psychological treatment.

Seeing this, Bai Haolin remembered that when Zhuang Xumao first arrived at the psychological support department, he asked him why he chose criminal psychology. Zhuang Xumao mentioned this at the time, but did not say that the perpetrator escaped from prison by using mental illness. Back then he already had a plan for what was going to happen.

On the 15th page, when Zhuang Xusubaru graduated from university, the recommendations written by the class tutor are usually some praise words, but there are a few words that are rarely seen in Zhuang Xusubaru’s recommendations: "I have an unusual curiosity about new things." , "Extraordinarily persistent in the belief", "Unique action", the subtext shows that the class teacher thinks that Zhuang Xu is fanatical, paranoid, and reckless in doing things.

Everything has two sides. There are many successful people who have made such comments, such as Yi Yunzhao. These words can also be used to describe him. From this point alone, it is impossible to judge what is wrong with Zhuang Xumao, but his mother died tragically to protect him, and his father Blame it on him for being violent at each other and seeing someone escape the legal sanction because of mental illness. These incidents are like inconspicuous paths, gradually leading Zhuang Xumao to deviate from the main road bit by bit.
