On June 5th, it started raining heavily, and it continued to rain continuously until ten o'clock in the evening.

Cao Caijing is an ordinary middle-aged woman who lives in the suburbs of southern Jiangsu and opens a hardware store in the town. She usually closes the door and goes home around nine o'clock in the evening. Because it rained today, it was later than usual.

It took an hour to go back.

I was walking on the path holding an umbrella. The rain had lightened up a lot, but it still kept falling, making me irritated.

As a woman, when walking alone on such a country road at night, she will inevitably feel a little scared and nervous. Thinking that her children are still waiting for her to come back, Cao Caijing quickens her pace.

This place is no better than in urban areas. Cameras are only available at some major intersections, and the street lights are a bit dim.

Because it rained and it was relatively late, I met almost no other pedestrians on the road, and it was quiet and eerie.

Until at the other end of the road, a middle-aged man walked towards me.

He was holding an umbrella, but his hair was wet, and the clothes on his body were obviously wet and stained.

Cao Caijing glanced at him curiously. The street lights reflected on his eyes. He stared at Cao Caijing. The whites of his eyes seemed to be bloodshot, and his whole person gave people a cold and terrifying feeling.

She immediately averted her eyes, not daring to look at him again, and her pace unknowingly quickened, and she even started to trot, her heart beating wildly.

Cao Caijing didn't look back, but she felt a chill running down her spine. The man seemed to be standing still, staring at her.

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

At this time, I looked back and saw that there was still half a human figure.

What's going on...

The look in that man's eyes is too scary...

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

Cao Caijing put away her umbrella, shook her head, and told her husband about the matter. The two of them didn't take it too seriously. For them, family and work are the most worrying things at the moment.

In the middle of the night, it rained heavily again.

…

The next day, the news broke.

"This station reports that at nine o'clock last night, an extremely bad robbery and murder occurred in Yangsong Town. The deceased was an ordinary taxi driver. The police are currently working hard to trace the whereabouts of the suspect..."

After Luo Qian received the report at six o'clock this morning, he quickly rushed to the crime scene with his criminal police team members to conduct investigation.

The crime scene has been protected by the local police station, and forensic and other functional departments are also on site to collect evidence.

The deceased was an ordinary taxi driver. His belongings, including those in the car, were looted. More than 2,000 yuan in cash, mobile phones and a gold wedding ring were not spared.

There were obvious signs of a struggle in the car, and there were knife wounds on both arms and thighs that were as deep as the bones. The real fatal thing was the knife that penetrated the liver. The technique was quite brutal.

Because it rained last night and it was located in a remote suburb, no one discovered the taxi parked in the woods until six o'clock this morning.

It is precisely because of this that under 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 gave a simulation report, briefly reconstructing the criminal process based on on-site reasoning and analysis of the modus operandi.

"This was a premeditated murder and robbery."

"The suspect has a certain awareness of counter-detection. In such weather and in the suburbs, he picked a taxi driver who carried a relatively large amount of cash and property. After committing the crime, he calmly disposed of the murder weapon and the fingerprints left behind.

, even the video equipment on the car was destroyed.”

"From the method of committing the crime, we speculate that the suspect's mental 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 and call the police, with the intention of getting away with the murder.

He committed the crime psychologically, and through forensic identification, it was found that the stabbing to the heart was not a fatal stabbing, but something he added later, which shows his psychological abnormality."

In the actual criminal investigation process, psychological profiling is only an auxiliary means for solving crimes. There are also psychologists in the police force to help draw psychological portraits of criminal suspects, but they are often only for reference. After all, evidence is what matters in solving crimes.

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

Luo Qian put a psychological portrait of the suspect in front of the screen. The portrait was of a young man in his mid-twenties, with ear-length hair, small and narrow eyes, a slightly crooked mouth, and uneven teeth.

"This is a portrait made by Professor Wu after analysis. Everyone can use it as a reference."

Everyone nodded and just took a look. After all, things like psychological profiling are not as mysterious as those in the movies. It would be great to be fooled once in ten times.

The only way to solve a crime is to have stronger evidence.

"We have retrieved surveillance videos from all surrounding road intersections, as well as surveillance videos from private shops where the suspect may have been caught."

"Everyone has also gone to the scene to investigate. The surveillance video is not perfect. It is extremely difficult for us to solve the case this time. If we cannot arrest the suspect in the shortest time, it will be even more difficult to arrest him later.

Already."

From the several surveillance videos played, you can see that the taxi passed through several intersections and left behind surveillance videos.

But the suspect was not photographed.

After the taxi left the town and entered the rural road, the surveillance video disappeared.

The criminal suspect had a strong sense of counter-reconnaissance. After killing the driver, he did not leave immediately, but stayed nearby for a long time.

And because it was raining, 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 seriousness of the case, local media outlets rushed to report it. Recently, this incident has also caused quite a stir in southern Jiangsu.

The criminal suspect could not be caught, and the citizens were a little panicked.

The taxi companies were the first to bear the brunt. The drivers took the opportunity to launch a protest. Not only was their work dangerous, but they were also exploited by the companies.

Conflicts from all walks of life triggered by this ensued, and naturally the city's criminal police brigade was under the greatest pressure.

Luo Qian was promoted to captain just this year. This case fell into his hands like a hot potato. If it was solved, he would be a big contributor. But the problem is that as time goes by, there is no clue to this case.

!

A week has passed, and presumably the criminal suspect has already fled Southern Jiangsu, but the case still needs to be solved. Public opinion is now huge, and almost all 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, offering a reward of 100,000 yuan for clues to solve the case, which also increased the strength of the criminal investigation team and established a 60-person case-solving team. Luo Qian served as the deputy team leader to conduct carpet-based investigations.

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

Hundreds of police officers set up checkpoints around Yangsong Town. Due to the lack of real images of the suspects, they could only search for clues through visits and patrols.

It was initially determined that migrants from out of town had committed the crime, so they checked all the hotels in the city one by one, traced every outsider who had recently entered and left Yangsong Town, and searched for suspicious persons who had recently left southern Jiangsu.

The murder weapon was not left behind, but it was not difficult to identify the knife used by the suspect through the wounds.

So the police officers visited all 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 wasting work, but it must be done.

…

In these days, Luo Qian had almost no rest.

At noon, he just finished checking the area, took the lunch box handed by his companion, sat down on the roadside, took a few bites, then lit a cigarette and smoked it.

After thinking for a while, he picked up his phone and sent a message to Yuan Jia.

Luo Qian: "Have you read all the recent events?"

Yuan Jia: "Look, isn't it hard to find?"

Luo Qian: "You are very thieves. No evidence was left behind. Looking for someone is like digging three feet into the ground. How do I find someone? Do you have any good suggestions?"

Yuan Jia naturally pays attention to the news, but the news reports and the clues obtained by the police are naturally very different.

Solving crimes is a matter for experts. If Luo Qian didn't tell him, he wouldn't ask.

Yuanjia: "How is it?"

Luo Qian thought for a while, and then mentioned some photos of the on-site investigation and the clues he had already grasped to Yuan Jia. He had lost miserably in the previous competition between the two of them to guess people's occupations, but he was also impressed by Yuan Jia's accuracy.

The judgment was very impressive.

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

A truly excellent criminal investigator must not be rigid in his thinking. As long as he can solve the case, he can use any help.

Soon, Yuanjia gave his own analysis and judgment.

"Male, about thirty to forty years old, about 1.7 meters tall, with scars on his head, fair skin, thin body, wide face, slanted eyes, thick eyebrows, flat nose, and thin beard.

"

"Is there any basis for this?"

"Guess."

Luo Qian replied angrily: "Stop causing trouble, get lost."

Yuanjia didn't lie to him, he was indeed guessing. They say that appearance comes from the heart, and Yuanjia deduced the other person's appearance from the other person's psychology.

There are naturally errors. For the same psychological portrait, Yuan Jia's is much more detailed than Professor Wu's, and there are also differences. Professor Wu thinks that the other person is a young man in his twenties, with long hair, uneven teeth, etc. This is not true for Yuan Jia.

is not reflected in the portrait given.

Psychological profiling requires a very broad range of knowledge, and the knowledge in each field must be extremely well covered. The more experiences or experiences, the more accurate the psychological portrait will be.
