track criminals

The entrance of the subway station was where the third body was found.Lying down on the edge of the steps, he passed away quietly.There were many passers-by, but none of them found it until the cleaner reminded the victim that he could not sleep here.

A push on the shoulder... the person is already cold.

Ying Shen and the others stood by the steps, looking around, looking for where they could easily see the situation here, and it was natural, without attracting others' attention.

In the end, a milk tea shop opposite was locked.

Jingle.

They opened the door and walked into the store, subconsciously glanced around, then walked to the front desk, looked up at the overhead camera, and took out their police ID, "Please show us the surveillance video."

王

The cashier looked hesitant, "That..."

Shen Wenqin frowned, "What's wrong?"

The cashier said: "The monitor has been broken for more than a month, and it has not been repaired. It is just a decoration."

"..."

Seeing the delicate expressions of the two policemen in front of him, the cashier felt a little ashamed, and said, "I don't know what Mr. Police Officer wants to know, I will try my best to help."

Shen Wenqin cleaned up his expression, regained his seriousness, and pointed to the seat by the window in the corner, "On April 4th, at three o'clock in the afternoon, the people sitting there have been looking out of the window for at least an hour. Do you have any impression?"

That is facing the subway station entrance, the best viewing position.

The cashier recalled, and then apologized: "I was not the person on duty that day, I will call and ask for you."

王

The phone was dialed three times before being connected, one time no one answered, and one time it was hung up neatly.The cashier glanced at the two policemen in embarrassment and gave a dry laugh.

"... You were on duty the day before yesterday. Do you have any impression of the customers sitting by the window at three o'clock in the afternoon... It was two policemen who came to ask... You haven't woken up yet?! What time is it? You are on duty this afternoon, don't you forget... ...you drank so much last night, you deserve it..."

The cashier was talking on the phone familiarly. Perhaps my friend was too embarrassed to be hangovered and cursed in front of the police. He unconsciously lowered his voice while talking, and finally hung up the phone, embarrassedly bowing his head to Ying Shen and Shen Wenqin who were standing opposite him, " I'm sorry, my colleague is hungover, he is not clear about what he says now, and probably can't remember what happened at that time."

"Then please give him his contact information."

The cashier immediately wrote down a string of mobile phone numbers, and when he handed them over, hesitantly said: "Mr. Police Officer, he drank a little too much, so he may hang up and refuse to answer."

"Write down the address too."

Cashier: "Uh...he just went to bed at noon, and he may not wake up until tomorrow morning. He drank a little too much, so..." It's useless to go.

Shen Wenqin listened, and smiled: "It sounds like he drank a little too much. Your boss didn't fire him, it's a conscience."

The cashier laughed dryly, thinking that the guy just didn't intend to do it anymore, that's why he was so bold.

Ying Shen said, "We'll come back tomorrow."

The cashier nodded, "Okay, I'll trouble the two police officers."

Back to the police station.

He Xijun's interrogation was about the same. When Ying Shen asked them, the result was that they were extremely cooperative. He was probably the most friendly and trustworthy suspect to the police in history, so it felt like they didn't find anything.

"Isn't there a study saying that there are natural killers? The brain structure of criminals is different from that of ordinary people. Looking back, there are several murderers in the family, which will be inherited, and the offspring are more likely to commit crimes." A police officer raised this point of view. .

Not talking nonsense, it is indeed scientific to a certain extent.Foreign researchers used brain CT scans of a large number of murderers as a demonstration and came to such a result.That itself has never committed any major crimes, just because the ancestors were guilty, they should also bear the bad influence, and if something happens, they will become the number one suspect of the police?This seems too unfair.Therefore, some radical researchers have also been criticized for utilitarianism. For the sake of society as a whole, individual rights are ignored, and behaviors that harm individuals will also spread. This is not a good way.

The leader of the task force said in a deep voice: "Just because of this suspicion? Then how do you convict him, saying that he is locked up because he has an unusual mind and is likely to be a criminal? Don't say anything false, you need evidence."

It's just a suspicion, there is no definite evidence, at most 24 hours of interrogation will be held, and the person will be released.

Speaking of falsehood, some police officers subconsciously looked at the two criminal psychology profilers who came to assist in the investigation, saying that psychological analysis sounds mysterious, and it cannot be used as evidence in court. Isn't it false?

"Don't look at us, you will also use this to solve the case, but you don't specialize in this, and analyze it based on criminal behavior, autopsy reports, on-site evidence, etc. There is evidence, not random guessing." Shen Wenqin explained.

Then they exchanged an awkward yet polite smile.

The technician called up He Xijun's biographical information, and then Ying Shen's job, whether this person fits the profile, and whether his past experience may have caused the murderous inducement.Generally speaking, in order to avoid subjective psychological influence, a specific person will not be used for reverse profiling, the scope of consideration is too narrow, and thinking is limited.But now the mother of the missing person is crouching dead in the police station, her eyes red, worrying about the safety of her only daughter.She is just an ordinary housewife, not some hot and powerful person, but she can turn over the clouds and find people from various channels.She was anxious, powerless, there was nothing she could do, and the police were her only hope.Of course, the police did not want to disappoint her.

He Xijun, 25 years old, fair-looking, well-behaved, has been excellent in grades since childhood, even if there are some minor problems, in general, he is a young man who is easy to like.During college, I had a girlfriend with a good relationship. After graduation, I planned to get married, but since his father's murder charge was confirmed and spread in the town, his reputation has also completely rotted. How many people are there for the murderer's son? Can you accept it?His girlfriend's family severed ties with him, bumped into walls everywhere, and was looked down upon by others. They actually tasted the warmth and coldness of human relationships in an instant, and everyone betrayed them.

Afterwards, he packed all his luggage, left the place where he grew up, and went to a city far away. No one knew him, so he could get rid of the past and start over.But what his father committed was a serious murder case, and he will be discovered one day.

王

And now, a young woman he knew and loved has disappeared, and he has serious suspicions.

But if his father is not mentioned, he is actually an ordinary normal person. He was excited by the criminal police drama, applied to the Public Security University, worked hard, and relentlessly pursued his dream. The murder case, the arrest of the suspect, and the rescue of a trafficked child all played a role in themselves.But the reality broke his dream. Before he graduated, the first murder suspect he contacted and assisted the police in arresting was his father.

Looking at these materials, the drama-like life, the police officers are a little silent.Without his father, maybe He Xijun would have become their colleague, young but passionate, full of vigor and vitality, he is an excellent newcomer.

After experiencing such ups and downs and sad things, what has changed in the original pure state of mind?neither knows.But none of those present wanted him to be another suspect.

After 24 hours, the police released him because there was no real evidence.

This is not to say that He Xijun has been completely cleared of suspicion. The police are still investigating. If there is evidence that he did it, he will return to the police station.Everything is only temporary.

It was hard to calm down the mother of the missing person and let her calm down a little.In just two hours, a new body was discovered. I don't know if this development should be called a coincidence or a slap in the face of fate.The mood of the police officers is very complicated.At this juncture, it seems that they let the suspect out to commit the crime.

The detection of the crime scene is the responsibility of the forensics department personnel.When Ying Shen and the others arrived, the work was not over yet, so they could only wait in the car.Perhaps because of illness, Ying Shen felt tired, leaned against the car window, and fell asleep at some point.Even at the scene, with the corpse not far away, he still slept soundly, and he was already used to it.

When woken up, Ying opened his eyes deeply, blinked twice, and then slowly came back to his senses, and found that he was wearing a black coat.Shen Wenqin beside him handed him cold medicine and a bottle of water, and said, "It's almost the end there, and it's our turn to work."

"Thank you." Ying Shen took it, raised his head to eat, and then asked, "Would you like to squint for a while?"

"No, I'm a night owl, and I feel more energetic at night." Shen Wenqin shrugged.

They got out of the car one after another and walked towards the location of the body.

Lifting off the cloth covering the corpse's face, he looked down at the victim.

"The identity of the deceased has been confirmed, it is Liao Jianing."

It was the woman who came to the police station for help, her daughter who had been missing for three days.

"There are traces of binding on the wrist and multiple bruises. Unlike the previous victims, the murderer's emotions were more intense. The experiment was destroyed, so he was angry?" Shen Wenqin said.

A police officer was watching and couldn't help but said: "Or was he interrogated by the police, emotionally irritable, and then vented on the victim?"

Of course it was He Xijun.Just after they were released, something like this happened, and they couldn't help being linked together.There have been many cases before. Among the suspects who were interrogated, one of them was the real murderer. He hid in it, and under the great pressure of being discovered by the police, he became irritable and became more violent and cruel. Take it out on the victim.

They looked at each other with complicated expressions.

Ying Shen said calmly, "We can give a profile now."
