crime profiler in the dark

Just as Bai Haolin was running around to investigate the case of the witness protection team being attacked, the throat-slitting case made some progress. Inspector Xu used all his contacts and finally obtained all the medicines in the city that Zhuang Xuya mentioned. Some specific drugs, and the list of patients diagnosed with mental illness, because it is related to the privacy of the patients, the court only gave the patient codes, symptoms and treatment methods, and did not completely hand over the confidential information of the patients to the police. The judge believes that unless the police can lock the suspect in a specific small number of people, they will not give support.

This is a very long list, and criminal profiling has strong professional skills, so the police officers headed by Sergeant Xu can't help much, and Bai Haolin has no time to spare, so the elimination can only be done by Zhuang Xumao Complete by one person.

White Tiger Police Station Administration Department

It was past eight o'clock in the evening, and the administration department had already left the building empty, leaving only Zhuang Xuxuan alone. Fortunately, the support department was not far away. The inspectors on the night shift had already started working, and the entire fourth floor was echoing with instruments. The "rustling" sound of the printer, the "beeping" sound of the printer, and the occasional chatting and laughing sounds of the inspectors are still lively.

Zhuang Xuxuan habitually spread all the materials on the table. According to the previous profile with Bai Haolin, those patients who were insane and unable to take care of themselves in daily life were excluded, and patients without violent tendencies were also excluded. There are also those patients who are closely supervised and have no time to commit crimes, and the list is finally reduced to less than [-] people.

It is a pity that the court's authorization does not give the patient's private information, such as age, gender, education level, etc.But Zhuang Xumao was not discouraged. He linked the materials of the three throat-slitting cases and gave a more comprehensive profile:

The victims in the three cases were all 20-35 years old, and according to the principle of psychological projection, the age of the murderer was also within this range;

Only 3% of serial killers are women, and their targets are usually family members, friends, colleagues and other people who have close relationships with them. Demonstrated a desire for violence, indicating that the perpetrator was male;

The murder method of cutting the throat shows extremely strong personal aggression and extreme desire for control, and at the same time has a strong visual impact, indicating that the murderer intends to attract people's attention, that is, the murderer feels that he has not received the attention he deserves, and should be classified as low-medium income group;

The murderer killed three times in public, but did not attract the attention of the witnesses at all. This shows that the murderer is a very inconspicuous person, which should be related to his lack of attention. That is to say, he is very inferior in daily life and interpersonal communication. Killing can make him confident;

In the third case, the method used by the murderer to cut his throat was very different from the previous two cases, indicating that he had a strong self-discipline behavior, while the first two cases were too ostentatious, which seemed incompatible with the third case and should be in line with the drug he took. Psychotropic drugs are related, and only psychiatrists can prescribe mood-controlling drugs, but psychological counselors cannot prescribe them, indicating that the murderer received drug treatment in a psychotherapy center with psychiatrists;

Although the murderer is a low-to-middle-income earner with poor interpersonal relationships, he has a high IQ and should have received a good education. He probably dropped out of school because of emotional instability, so he is cynical and has strong dissatisfaction with society. antisocial personality traits

After Zhuang Xusubaru finished the profile, he read it back and forth twice, and felt that there was no problem, so he sorted it out and printed two copies. He went straight to the criminal investigation department, and it happened that Inspector Zhu and Inspector Xu were talking.

"Two sheriffs." Zhuang Xumao interrupted their conversation with a smile.

"Hey, Xiao Zhuang, why aren't you off work yet?" Sergeant Zhu was a little surprised by Zhuang Xumao's arrival.

"It must be as busy as us with the throat-cutting case." Sergeant Xu noticed that Zhuang Xumao was holding the documents in his hand, eager to know what he found, and said, "Have you done the profiling?"

"It's just my personal opinion, and the two police chiefs are for reference only." Zhuang Xumao handed his profiling results to the two police chiefs.

Inspector Zhu and Inspector Xu received Zhuang Xusubaru's profiling results, Inspector Zhu took out reading glasses, Inspector Xu frowned, and the criminal investigation department was so quiet that only the breathing of the three could be heard.

After a while, Sergeant Zhu put down the materials first, and Sergeant Xu also put down the materials later. The two looked at each other, and then at Zhuang Xumao who still had a smile on his face. Sergeant Zhu spoke first:

"Xiao Zhuang, it's rare that you can give such a precise profile at such a young age, very good!"

"Is this profiling also Haolin's conclusion?" Superintendent Xu was quick-tempered, and pointed out the problems he and Chief Zhu had in common. The profile is accurate, compared to the newcomer Zhuang Xusubaru, the two want to know what Bai Haolin means.

"Brother Haolin is involved in another case, but we discussed it before, and he agrees with this profile." Zhuang Xusubaru's smile was a little restrained, only the corners of his lips still had a slight curvature.

"It's pretty good. You can have such a level when you just came here. It seems that everyone in the psychological support department has elite soldiers and strong generals!" Sergeant Zhu encouraged Zhuang Xumao when he saw that Zhuang Xumao was slightly displeased.

"I'm just trying to figure it out. I hope it can help the two sheriffs." Zhuang Xumao said modestly, showing two cute canine teeth.

After the three of them were courteous again, Zhuang Xumao left the criminal investigation department. Inspector Zhu said to Inspector Xu:

"I think it's better to show this profile to Xiaobai again."

"Alright, I'll call him." Sergeant Xu dialed Bai Haolin's phone.

At this time, Bai Haolin had just left the Qinglong Police Station and was about to drive home when he received a call from Police Chief Xu. Some worried about the accuracy of the profile, so they simply returned to the Baihu Police Station.
