I'm in a mental hospital, and a rich and beautiful woman forced me to be her boyfriend

Chapter 137

In the office.

Liu Guanghai was silent for a while, then nodded and said,"Of course I know."

"This is one of the main reasons why it is strictly forbidden to disclose case details in serial murder cases."

Generally speaking, serial murder cases have obvious characteristics.

For example, the killing method is the same.

The crime scene is similar.

There are even obvious killing symbols such as cutting off fixed organs.

Once the details of the case are disclosed before the murderer is caught, there is a possibility that other murderers will imitate the crime in order to avoid investigation.

They hope to attribute the death of the victim to the serial killer.

In this way, they can escape legal sanctions. There have been such cases in the past. Liu Guanghai continued:"But now, you can't be sure that this is a serial murder case.

"and"

"Copycat killings cannot be prevented"

"Even if it happens, we have no way to deal with it."

"Your focus is still on this heart-digging case."

Wang Ze nodded:"I know"

"I just want to make sure we are prepared."

27"I hope it won’t be that serious."

……

Meeting room.

The criminal investigation team gathered.

Bao Qu is reporting the results of the investigation.

"Captain Li, we have visited all the shops and communities within a few kilometers of the crime scene."

"Many people knew Qi Hui, but no one said they had seen any suspicious man."

"We searched the surrounding area, but didn't find the murder weapon."

After listening, Li Xiangbin looked at Wang Xiaotong and asked,"Where's the surveillance?"

Wang Xiaotong said,"The nearest surveillance is a hundred meters away from the demolition area."

"All on the main road"

"I have recorded all the vehicles that passed by on the night of the incident and am checking them one by one."

"At present, no suspicious persons matching the suspect's characteristics have been found."

"From the road distribution on site"

"There is a high possibility that the suspect has no means of transportation."

Hearing this, Li Xiangbin held onto the table and said,"It's like looking for a needle in a haystack."

"We now have the suspect's DNA."

"But I can't find him"

"Could it be that this was a random crime?"

Bao Qu said,"Captain Li, I think we should just classify it as a random crime."

"Qi Hui's interpersonal relationships have been thoroughly investigated, and the DNA collection is about to exceed 30 people."

"This is not a solution."

Bang!

At this time, there was a sound of a ballpoint pen falling.

Everyone turned their heads subconsciously.

They found that it was Wang Ze, who was spinning the pen there.

Unfortunately, his level was not high enough and he couldn't keep it steady.

Li Xiangbin said:"Wang Ze, do you have any direction?"

Wang Ze picked up the fallen ballpoint pen and said:"My opinion is the same as Bao Qu's."

"This case is treated as a random crime."

"Since this is a random crime, the direction of our investigation must change."

"Just like the previous case of incitement to suicide, analyze the external characteristics of the murderer."

Li Xiangbin knew.

The other party meant to use criminal psychological profiling to directly identify the murderer in the vast crowd.

The difficulty is the greatest.

Generally, serial murder cases are solved because new victims appear. On the basis of analyzing the murderer's psychological safety zone, extensive investigation is carried out.

The tolerance rate is high, but it is time-consuming and labor-intensive.

The results are also difficult to guarantee.

If the criminal psychological profile can be accurately drawn, the tolerance rate is low. (To read the violent novel, go to Faloo Novel Network!)

But if it succeeds, it can effectively prevent new victims from appearing.

With the least loss of manpower and material resources, the murderer can be caught.

As Wang Ze just said, the previous case of Wei Yingxia is a good example.

Unfortunately, criminal psychological profiling experts are too rare.

Fortunately, there is one in their team.

"Are you sure?"

Li Xiangbin asked.

Wang Ze hesitated for a moment and said,"Now I am only 70% sure. You can give it a try."

"Gender has been determined, male"

"Let’s talk about age first"

"Histrionic personality disorder, most common in people under 25 years old"

"Above 25, the psychological state tends to be stable"

"Based on the murderer's height, we can narrow it down to between 18 and 25 years old."

"Let's talk about career"

"The murderer was still roaming the streets late at night."

"I don't think he has a relatively stable career."

"Also, people with histrionic personality disorder have difficulty handling interpersonal relationships"

"Then his profession may not require much social interaction."

"For example, sales can be excluded directly"

"According to the autopsy report, the murderer strangled the victim to death with great force, causing his larynx to break."

"What kind of people have such great strength?"

"From this point of view, if fitness factors are not taken into consideration, clerical jobs such as office workers and programmers can be ruled out."

"So"

"What kind of job is there that doesn’t require social interaction, isn’t unstable, and can exercise muscle strength?"

Wang Xiaotong:"Construction site?"

Bao Qu:"Factory?"

Wang Zedao:"I prefer a job like a construction site, or a job like a porter."

"Finally, let's talk about his murder characteristics."

"Strangle someone to death and eat their heart raw"

"There must be a reason for this."

"No one would do such a bloody and strange thing for no reason.

Li Xiangbin nodded and said,"It is indeed very strange."

"There have been similar cases across the country where the murderer would take out the internal organs and take them away after killing the victim."

"But this is the first time I have seen someone eat it on the spot."
