However, psychological profiling is based on behavioral statistics, which is somewhat similar to the existence of 'experience'. Just like an experienced policeman can tell who is a thief at a glance, there will also be individual errors.

Yuan Jia is not 100% sure, but he is still 30% certain.

Don't underestimate this 30%. Professor Wu's confidence in his own psychological portrait is not even 10%.

Luo Qian said that, but he still carefully wrote down the physical characteristics given by Yuan Jia. As his best friend, he knew that Yuan Jia would not make fun of him. Since he said so, it would naturally be

There is a reason for it.

Yuan Jia: "As for the portrait, you can simply refer to it and I will give you some basis-based judgments."

Luo Qian: "Say."

Yuanjia: "He has severe antisocial personality disorder."

Patients with antisocial personality disorder usually do not think they are sick and do not need treatment. This is also the biggest potential harm of antisocial personality disorder and the reason why it is difficult to treat.

People with antisocial personality disorder often engage in illegal behaviors, such as stealing, fighting, robbing, wounding, etc.

He has an extremely self-interested personality and does not hesitate to harm others in order to satisfy his own interests or pleasure.

He has an impulsive and reckless personality, does things without considering the consequences, is irritable and extremely irresponsible.

Even after committing actions that harm the lives or interests of others, they have no remorse. Instead, they think that the other person is stupid or deserves their punishment, and use reasons such as "life is unfair" to excuse themselves.

The incidence of antisocial personality disorder in normal people is very low, but in some special circumstances, the incidence can be as high as more than 50%.

For example, prisons, drug rehabilitation centers, high-pressure judicial environments, or social and cultural groups such as economic poverty and migration.

Similarly, brain trauma will also increase the risk of disease to a certain extent, especially if the injury occurs at a young age, but parents and others are relatively indifferent and deal with it simply.

After telling Luo Qian about the origin and manifestation of this mental illness, Yuan Jia gave his own judgment.

Yuan Jia: "You just said that Professor Wu suspected that people from other places committed the crime. This judgment may be wrong. The suspect is indeed not a local. He may have migrated here a few years ago and settled here. From what he said,

From the familiarity of nearby roads and cameras, we can know that he is not traveling to commit crimes, and may even live around Yangsong Town."

After listening to Yuan Jia's words, Luo Qian became slightly excited, and after his description, his ideas gradually became clearer.

The most important thing is that as long as the criminal suspect has not left the local area, the difficulty of solving the case will be much reduced!

During this period, the investigation of people coming in and out of other places was extremely difficult, with a huge workload and no accurate clues.

Yuan Jia: "Based on this, we can deduce some behavioral and experience characteristics of the criminal suspect."

Yuan Jia: "Currently unemployed, but I have had the experience of changing jobs frequently. There are many factories around Yangsong Town. You can select personnel records for investigation."

Yuan Jia: "I have financial constraints and live alone. My parents are not here. I have no wife or children. I am single. I have lived here for many years, but I still have a strong foreign accent."

Yuan Jia: "I have debts and like to be alone."

Yuan Jia: "I have a criminal record or have been in a drug rehabilitation center."

Yuan Jia: "There may be scars on the forehead or the back of the head. He suffered a relatively serious impact injury when he was young."

Yuan Jia: "Try to investigate in this direction."

Luo Qian smoked one cigarette after another, but the light in his eyes became brighter and brighter. After Yuan Jia's analysis, his thinking became completely clear.

Yangsong Town is just a small town. It meets these characteristics at the same time, or even if there are only two or three items, there are not many people. It only takes three days at most to complete the investigation.

He became excited, and time was running out. The movements in Yangsong Town these days may have frightened the criminal suspect into running away, but as long as he knew the person's last name as soon as possible, he could always be caught no matter where he ran.

.

Luo Qian: "Awesome, if you are caught, I will apply for great merit for you."

Yuanjia: "I wish you good luck."

Putting down his cell phone, Luo Qian drank half a bottle of mineral water and took the pager to gather the team members for a meeting.

…

Before everyone had arrived, a team member made an urgent announcement.

"Head! Found the clue!"

"What's going on?"

"When we were investigating a hardware store, the proprietress reported to us that on the night of the incident, she met a middle-aged man with a fierce look on her way home. The time and location when she met this man happened to be

It coincides with the time of the crime, and that man is a serious suspect!"

Luo Qian's pupils shrank, he asked about the location of the hardware store, and rushed there immediately.

Cao Caijing has never been so nervous as she is now. Several tall detectives came to the hardware store, and even the air became a little depressed.

Ever since she met the middle-aged man that night, she had been thinking about it. Then the news of the murder came the next day, and she was even more timid.

She originally wanted to report the clues the next day, but her husband persuaded her not to. After all, both husband and wife worked in the town, and the children and the elderly were afraid of being unsafe at home. Besides, she only glanced at each other briefly.

, and it is not certain whether he is the criminal suspect.

She felt uneasy with this mentality for a week, and it wasn't until the police came to the store to inquire that she couldn't help but speak out.

"Ms. Cao, don't be nervous. Please describe what happened in detail."

"That person, shouldn't he take revenge..."

"You can trust us completely."

Cao Caijing began to talk intermittently, and the police officer quickly took notes.

"It closed late that night, and it was raining again, so I..."

"He is holding an umbrella, but he is wet?"

"It seems... I can't remember exactly... I just glanced at him. He looked very scary. I didn't even look at him for a second, and I was so scared that I hurried away..."

"What color umbrella is he holding?"

"Black...not...it seems to be blue...not..."

Cao Caijing frowned and recalled, but she couldn't remember anything.

Due to normal people's psychological defense mechanism, the scene has been blurred by memory modifications in response to the panic that night, and it was only a glance for a second, and I didn't see the other person's appearance clearly. Now I'm recalling it in my memory.

When I got up, there were only vague shadows.

"It's okay, Ms. Cao, don't worry, slowly recall, what style and color of clothes is he wearing?"

"Wear... wear..."

Cao Caijing struggled to recall, but the more actively she tried to recall, the less she could remember the appearance of the other party.

The only thing that I remember most deeply is those eyes. The pupils were staring at her, the whites of the eyes were bloodshot, like a bloodthirsty beast.

These eyes attracted all her attention, so that after the memory was processed, the rest of the appearance and clothing characteristics became blurred.

"I'm sorry, officer... I really can't remember. I'm old and I often forget things. Maybe I saw it wrong..."

Cao Caijing shook her head repeatedly, she had indeed tried her best.

Luo Qian calmed her down. It has been a week since the case occurred. Cao Caijing is the only possible witness, and any words she says are precious clues.

With the help of the artist, I drew the eyes according to Cao Caijing's description.

It’s the same as Yuan Jia’s judgment just now: slanted eyes and thick eyebrows.

Luo Qian held an emergency team meeting, and the police officers re-adjusted the direction of the investigation, focusing on several special points raised by Yuan Jia.

But even if a suspect who meets these conditions is found, there is no tangible evidence to convict him. The only breakthrough is Cao Caijing, who cannot remember the clear face of the other party.

Luo Qian: "What should we do now? If she could remember it, the case would be much smoother."

Yuanjia: "She saw her face, right?"

Luo Qian: "Yes, but now I only remember the eyes, not even the other person's clothes."

Last time about personality disorder, Yuan Jia also talked to Luo Qian about people's memories.

Memory is a very special existence. The memory in the subjective consciousness is not a record, but has traces of processing.

After Cao Caijing's memory processing, except for the eyes, the rest of the appearance features were weakened, and she even made up unreal pictures in her mind.

But subconscious memories are real.

The human subconscious mind can accurately record what the conscious mind has taken in, and hypnosis can access this incredible and infinitely rich memory bank.

Using hypnosis for questioning can yield more than 50% more relevant clues than ordinary verbal questioning.

Yuanjia: "Would you consider hiring me as a special consultant?"

Luo Qian: "Are you sure?"

Yuan Jia: “It can be restored.”

Luo Qian didn't reply anymore, got into the police car, and went directly to pick up the person.
