On the 5th of June, it rained heavily, and it continued to rain until 10 o'clock in the evening.

Cao Caijing, an ordinary middle-aged woman who lives in the suburbs of southern Jiangsu and owns a hardware store in the town, usually closes her doors at about 9 p.m. and goes home an hour later than usual because of the rain today.

Walking on the path with an umbrella, the rain has been much lighter, but it still keeps falling, which makes people irritable.

As a woman, when walking alone on this kind of country road at night, it is inevitable that there will be some fear and tension in her heart, and thinking that the children at home are still waiting for her to come back, Cao Caijing sped up her pace.

It's not like an urban area, cameras are only available at some major intersections, and the street lights are a little dim.

Because of the rain and the late period, there were almost no other pedestrians on the road, and it was quiet and a little weird.

Until the other end of the road, a middle-aged man came over.

He was holding an umbrella, but his hair was wet, and his clothes were visibly wet and stained.

Cao Caijing glanced at him curiously, the street lamp refracted on his eyes, he stared at Cao Caijing, the whites of his eyes seemed to be bloodshot, and the whole person gave people a cold and terrifying feeling.

Even if she looked away, she didn't dare to look at him anymore, her steps unconsciously accelerated, and she even trotted up, her heart pounding.

Cao Caijing didn't look back, but she felt a chill down her spine, and the person seemed to be standing still, staring at her all the time.

It wasn't until she walked far away and saw the warm lights on at the door of her house that Cao Caijing breathed a sigh of relief.

At this time, when I looked back, there was still half a figure there.

What's going on......

That man's eyes are terrifying, aren't they......

It seems that I will have to go home early in the future......

Cao Caijing put away the umbrella, shook her head, and told her husband about it, and the two didn't pay much attention to it.

In the middle of the night, it rained heavily.

......

The next day, the news blew up.

"This station reported that at nine o'clock last night, there was an extremely bad robbery and murder case in Yangsong Town, the deceased was an ordinary taxi driver, and the police are currently making every effort to track down the whereabouts of the suspect......"

After Luo Qian received the report at 6 o'clock this morning, he rushed to the scene of the crime with his criminal police team members to investigate.

The scene of the crime has been protected by the local police station, and forensic and other functional departments are also collecting evidence at the scene.

The deceased was an ordinary taxi driver, and his body, including the belongings in the car, was looted, and he did not let go of more than 2,000 yuan in cash, mobile phones, and a gold ring for his wedding.

There were obvious signs of a fight in the car, and there were deep knife wounds to the arms and thighs, and the real fatal was a knife that was stabbed into the liver, and the technique was quite brutal.

Because of the rain last night and the fact that it is located in the middle of nowhere, it was not until six o'clock this morning that the taxi parked in the grove was found.

It is precisely because of this that under the cleaning of the heavy rain, there is very little effective evidence left at the crime scene, which greatly increases the difficulty of solving the case.

During the afternoon meeting, Luo Qian also made a simulation report, and simply restored the criminal process according to the reasoning at the scene and the analysis of the modus operandi.

"It was a premeditated homicide robbery. ”

"The suspect has a certain sense of anti-reconnaissance, such weather and suburbs, he picked a taxi driver who carried a relatively large amount of cash and property, and after committing the crime, he was able to calmly dispose of the murder weapon and the fingerprints left behind, and even the on-board video equipment was destroyed. ”

"From the point of view of the modus operandi, we speculate that the suspect's psychological state is distorted, he did not impulsively kill because of the driver's panic and shouting, but was afraid that the driver would recognize his appearance, afraid that he would call the police, and committed the crime with the psychology of being at large after the murder. ”

Psychological profiling in the actual criminal investigation process, is only equivalent to the auxiliary means of solving the case, and there are also psychological experts in the police force to help draw a psychological portrait of the suspect, but it can often only be to the extent of reference, after all, solving the case is based on evidence.

Witnesses, physical evidence, audio-visual materials, appraisal conclusions, on-site records, inquest records, etc., are statutory evidence.

Luo Qian put a psychological portrait of the suspect in front of the screen, the portrait is a young man about twenty-five years old, with long hair over the ears, small and narrow eyes, a slightly crooked mouth, and uneven teeth.

This is a portrait made by Professor Wu after analysis, and you can use it for your reference. ”

Everyone nodded, just to see, after all, this kind of thing is as mysterious as in the movie, and it is great to be able to be in the middle of ten times.

Solving the case depends on stronger evidence.

"We have retrieved surveillance footage from all the surrounding road intersections, as well as captured surveillance footage of the suspect's private shop. ”

"Everyone has also gone to the scene to investigate, the surveillance video is not perfect, this time we are extremely difficult to solve the case, if we can't catch the suspect in the shortest possible time, then it will be even more difficult to arrest him later. ”

From the several surveillance video videos played, you can see that the taxi passed through several intersections and stayed to monitor the video.

But no suspect was photographed.

After the taxi left the town and entered the village road, the surveillance footage was gone.

The suspect has a strong sense of anti-reconnaissance, and after killing the driver, he did not leave as soon as possible, but stayed nearby for a long time.

Moreover, because of the rain, the pedestrians photographed at night were all holding umbrellas, and their faces could not be seen clearly.

How to solve such an unsolved case?

......

Because of the viciousness of the case, local Taiwan media rushed to report it, and the recent incident has also caused a lot of turmoil in southern Jiangsu.

If the suspect cannot be caught, some citizens are panicked.

First and foremost are taxi companies, where drivers are taking the opportunity to protest against the dangers of their work and exploitation by their companies.

The resulting contradictions from all walks of life followed, and the greatest pressure was naturally the Municipal Criminal Police Brigade.

Luo Qian was only promoted to captain this year, and this case fell into his hands, just like a hot potato, and if it is broken, it is naturally a great hero, but the problem is that seeing the time pass day by day, there is no clue about this case!

It's been a week, and the suspect has already fled southern Jiangsu, but the case is still about to be solved, and now the public opinion is huge, and almost all the people in southern Jiangsu are paying attention to the progress of this matter.

The municipal party committee and municipal government also attached great importance to this, and offered a reward of 100,000 yuan to collect clues to solve the case, which also increased the strength of the criminal investigation team, and set up a special team of 60 people to solve the case, with Luo Qian as the deputy team leader, to conduct a carpet investigation.

In the absence of clues, this may seem clumsy, but it is the most effective.

Hundreds of police officers set up cards around Yangsong Town to investigate, because of the lack of real images of criminal suspects, they can only find clues through a carpet search like visiting and touching rows.

The preliminary judgment was that the floating population from other places committed the crime, so they checked the hotels in the city one by one, traced every foreigner who had recently entered and left Yangsong Town, and looked for suspicious people who had recently left southern Jiangsu.

The murder weapon was not left, but it was not difficult to reverse the knife used by the suspect through the wound.

So the officers visited all the local hardware stores, shopping malls, supermarkets, etc.

This kind of investigation work is the most tiring, and if the direction is wrong, it is equivalent to working in vain, but you can't stop doing it.

......

These days, Luo Qian has hardly rested.

At noon, he had just finished inspecting the place, took the boxed lunch handed by his companion, sat down on the side of the road and took two puffs, then lit a cigarette and smoked it.

After thinking about it, he picked up his phone and sent a message to Yuanjia.

Luo Qian: "You've seen everything recently, right?"

Yuan Jia: "Look, it's hard to find, right?"

Luo Qian: "The chicken thief is very, there is no evidence left, looking for someone is like digging three feet into the ground, how to find it, do you have any good suggestions?"

Yuan Jia naturally pays attention to the news, but there is naturally a big difference between the news report and the clues held by the police.

Solving the case is something that an insider does, and if Luo Qian doesn't tell him, he won't ask.

Yuanjia: "How's that?"

Luo Qian thought about it, and then mentioned some photos of the scene investigation and the clues he had already mastered to Yuan Jia, the previous competition between the two speculated on people's careers, and he lost badly enough, but he was also very impressed by Yuan Jia's accurate judgment.

Compared with the portrait given by Professor Wu, he trusts Yuan Jia's judgment more.

A really good criminal investigator must not be rigid in thinking, as long as he can solve the case, any help can be used.

Soon, Yuan Jia gave his own analysis and judgment.

"Male, about thirty to forty years old, about one meter seven tall, with a scar on his head, white skin, a thinner body, a wider face, slanted eyes, thick eyebrows, a flat nose, and a thin beard. ”

"Is there any basis?"

"Guess. ”

Luo Qian replied angrily: "Don't add to the chaos, get out." ”

Yuan Jia didn't lie to him, he did guess, they all said that the relationship was born from the heart, and Yuan Jia was reversed from the other party's psychology to the other party's appearance.

Errors are naturally there, the same psychological portrait, Yuan Jia is much more detailed than Professor Wu's, and there are also differences, Professor Wu feels that the other party is a young man in his twenties, and long hair, uneven teeth, etc., which is not reflected in the portrait given by Yuan Jia.

Psychological profiling requires a very wide range of knowledge, and the knowledge in all fields must cover extremely well, and the more you experience or experience, the more accurate the psychological portrait will be.

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

Yuanjia is not 100% sure, but 30% is still there.

Don't underestimate this 30 percent, Professor Wu's grasp of his own psychological portrait is not even 10 percent.

Luo Qian said so, but he still carefully wrote down the appearance characteristics given by Yuan Jia, as a best friend, he knew that Yuan Jia would naturally not joke with him, since he said so, it was naturally his reason.

Yuan Jia: "If you want to draw a portrait, you can simply refer to it, and I will give you some well-founded judgments." ”

Luo Qian: "Say." ”

Yuan Jia: "He has a severe antisocial personality disorder. ”

People with antisocial personality disorder often don't think they have a disease and don't need treatment, which is why antisocial personality disorder is the biggest potential harm and difficult to treat.

People with antisocial personality disorder often engage in illegal behaviors, such as stealing, fighting, robbing, hurting others, and so on.

The character is extremely self-interested, and he does not hesitate to hurt others in order to satisfy his own interests or pleasures.

The personality is impulsive and reckless, does things without thinking about the consequences, is irritable and irritable, and is extremely irresponsible.

Even after committing acts that harm the lives or interests of others, they do not have remorse, but think that the other party is stupid or deserve it, 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 50% or more.

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

Similarly, trauma to the brain can also increase the risk of illness to a certain extent, especially when it is injured at a young age, but parents and others are more indifferent and simple to deal with.

After talking to Luo Qian about the emergence and manifestation of this mental illness, Yuan Jia gave his own judgment.

Yuan Jia: "You just said that Professor Wu suspected that the people from other places were fleeing to commit 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 his familiarity with the nearby roads, cameras, etc., it can be known that he is not a wandering crime, and may even live around Yangsong Town." ”

Listening to Yuan Jia's words, Luo Qian became slightly excited, and under his description, his thoughts gradually became clear.

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

During this period, the investigation of the non-local population in and out can be described as miserable, the workload is extremely large, and no accurate clues can be found.

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

Yuan Jia: "I am currently unemployed, but I have the experience of frequently changing jobs, and there are many factories around Yangsong Town, and you can pick up personnel records for investigation. ”

Yuan Jia: "Financially constrained, living alone, parents are not in the local area, no wife and children, single, living in the local area for many years, but still have a relatively heavy foreign accent. ”

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

Yuan Jia: "I had a criminal record, or I stayed in a drug rehabilitation center. ”

Yuan Jia: "There may be a scar on the forehead or the back of the head, and I have suffered a relatively serious impact injury when I was a child. ”

Yuan Jia: "Let's try to investigate in this direction." ”

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

Yangsong Town is just a small town, and there are not many people who meet these characteristics at the same time, or even if there are only two or three of them, and it only takes three days at most to complete the investigation.

He was excited, time was pressing, the movements in Yangsong Town these days may have also made the suspect run away in fear, but as long as he knew who the other party's surname was as soon as possible, then no matter where he ran, he would always be able to get it back.

Luo Qian: "Awesome, if you catch it, I'll give you a great application." ”

Yuanjia: "Good luck with you. ”

Putting down the mobile phone, Luo Qian grunted half a bottle of mineral water, and took the pager to let the group members gather for a meeting.

......

Before anyone arrived, a team member made an urgent report.

"Head, clue found!"

"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 on the way home, with a fierce gaze, and the time and location of the man she met coincided with the time of the crime, and the man was a major suspect!"

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

Cao Caijing has never been so nervous as she is now, there are several tall criminal policemen in the hardware store, and even the air is a little depressed.

Since she met the middle-aged man that night, she has been thinking about it in her heart, and then the news of the murder came the next day, and she was even more confused when she was timid.

Originally, she wanted to report the clues the next day, but her husband persuaded her not to, after all, the husband and wife both worked in the town, and the children and the elderly were afraid that it would not be safe at home, besides, she just glanced at each other in a hurry, and she was not sure whether it was a suspect.

With this mentality for a week, she couldn't help but say it until the police came to the store to ask.

"Ms. Cao, you don't need to be nervous, please describe what happened in detail. ”

"That person, should, shouldn't retaliate......"

"You can trust us. ”

Cao Caijing began to speak intermittently, and the police officer quickly made notes.

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

"He's holding an umbrella, but he's wet?"

"It seems to be...... I don't remember exactly...... I just looked at him, he looked so scary, I didn't even look at him for a second, I was so scared that I hurried away......"

"What color umbrella is he carrying?"

"Black... No... It seems to be blue... It's not ......"

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

Out of the psychological defense mechanism of normal people, for the horror of that night, the picture has been blurred by memory modification, and it was only a glance for a second, and he didn't see the other party's appearance too clearly, and now in the memory, there is only a vague shadow.

"It's okay, Ms. Cao doesn't need to be in a hurry, slowly recall, what style and color of clothes is he wearing?"

"Wear ...... Wear ......"

Cao Caijing reminisced with difficulty, but the more she took the initiative to recall, the more she couldn't remember what the other party looked like.

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

These eyes attracted all her attention, so much so that after the processing of her memory, the rest of her appearance and clothing features became blurred.

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

Cao Caijing shook her head again and again, she did her best.

Luo Qian calmed her emotions, it has been a week since the case happened, Cao Caijing is the only possible eyewitness, and any word she says is a precious clue.

With the help of the artist, the eyes were drawn according to Cao Caijing's description.

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

Luo Qian urgently convened a team meeting, and the police readjusted the direction of the investigation, and focused on several special points proposed by Yuan Jia.

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

Luo Qian: "What to do now? If she can remember, then the case will be much smoother." ”

Yuan Jia: "She saw the straight face, right?"

Luo Qian: "Yes, but now I only remember the eyes, and I don't even remember the other party's clothes." ”

The last time there was a personality disorder, Yuan Jia also talked to Luo Qian about people's memories.

Memory is a very special existence, and the memory in the subjective consciousness is not a record, but there will be traces of processing.

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

But the subconscious memories are real.

The human subconscious mind can correctly record what the conscious mind ingests, and hypnosis can enter this incredibly rich memory bank.

Hypnosis can be used to interrogate more than 50 percent more relevant clues than ordinary verbal questioning.

Yuan Jia: "Do you want to consider hiring me as a special consultant?"

Luo Qian: "Sure?"

Yuan Jia: "It can be restored." ”

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