As soon as Wei Jian's words fell, everyone stopped what they were doing and gathered around with their ears pricked up.

Although everyone is a criminal policeman, they have always been pragmatic people who rely on evidence to speak, and the academic school of "criminal psychology", even if anyone has heard of it, has never seen it.

Now the director has hired an intern in this area and said that he wants to use new disciplines to help them solve cases. People are very skeptical about the efficacy of this thing, but since someone is willing to share it, they are happy to listen to it.

It's just a curiosity, and there's no harm in it anyway...

Under everyone's eager gaze, Long Yi said slowly: "The deceased was killed in the middle of the night last night, there is no trace of the door being broken, it can be speculated that an acquaintance committed the crime;

Wei Jian sneered, "Judging from the scars on the deceased's body, heh, the furnishings at the scene are so messy, you can't see it?"

The dragon choked, and the deceased was lying in the living room, bleeding all over the ground, and she really dared not observe the scene carefully.

The sofa cushions are very messy, the torn pillows reveal the cotton wool inside, the set of ceramic cups on the coffee table is broken twice, and the chair is overturned on the ground...

Ryuichi's face was a little red: "I'm sorry, I'm actually..."

He Gu interrupted her: "Go on." ”

It was still a cold tone, but Long Yi seemed to hear a hint of encouragement from it.

"The offender is a male between 30 and 35 years old, around 175-178 in height, with a thin build, good appearance and a high level of education.

The offender had been abused by women as a child, and had recently been stimulated by the outside world, either unemployed, or seen someone, and had a car. ”

"Basis?"

The question is still asked.

Ryuichi explained: "Judging from the intensity of the victim's struggle, the size difference between the criminal and her will not be too big, otherwise the criminal will be able to subdue him in an instant;

The victim had multiple stab wounds, and it was obvious that the offender was not an ordinary homicide, but an act of anger out of revenge;

Under the deceased; The body is torn apart by a human instrument, and the person who can do such a thing is somewhat psychologically perverted, and must have been injured in this regard when he was a child, and given the sex of the deceased, it must be a woman who causes such harm to the offender;

Listening to Long's meticulous analysis, Wei Jian couldn't help but put away his previous careless attitude.

His gaze kept falling on Long Yi's face.

Xu was a little nervous, her fair skin was covered with a thin layer of fine sweat, under the bright sun, the water vapor was thick, and the girl's face was particularly pretty and vivid, which was completely different from the usual childish female college student.

That's the charm of professionalism.

Wei Jian thought to herself.

Long Yiwu immersed himself in reasoning, "Most of the peak crimes of psychopaths are concentrated between 25 and 35 years old, and according to the age and taste of the victim, the criminal should be older than 30 years old;

The deceased was a woman who lived alone, and was able to open the door for a man in the middle of the night, or leave a man in her house until midnight, and the relationship between the two must have been close enough;

As a cosmetics seller, and has a good taste - you can look at the deceased's bedroom layout and the quality of the clothes in the wardrobe, the appearance and temperament of the man who can enter her house must not be too bad;

It began to rain at about half past eight last night and lasted until five o'clock this morning, and the road leading to the entrance of the deceased's residential complex was a dirt road, and if you walked, your shoes would definitely be stained with mud. But you see, there were only a few mud stains on the doormat at the door, and the marks matched the black high heels next to it, and there were no muddy footprints of men in the corridor, so the criminals must have had a car. ”

There was silence in the room, and it was clear that everyone was digesting the reasoning.

After a while, Xiao An raised his hand and asked weakly, "What if they are taking a taxi?"

Long Yi nodded solemnly, "I can't rule out this possibility." However, I think that with the deceased's appearance and income, it is less likely that he will have a relationship with a man who does not own a car. ”

As soon as Long saw that He Gu was not in deep thought like the others, she knew that he could completely follow her train of thought, so she walked up to He Gu and whispered: "Master, given the relationship between the criminal and the deceased and the particularity of the tools used to commit the crime, this is obviously a temporary murder, but since the criminal is a psychopath, once the hidden nature is aroused... I'm afraid there will be similar cases in the future. ”

Xiao An was horrified: "What, what do you mean it will happen..."

He was the closest, and he had just heard it.

He Gu looked directly at Long Yi with his bottomless eyes.

Rao is conceited talent, under such a deep gaze, Long Yi couldn't help but feel a little flustered.

But she believed in her own reasoning, and met He Gu's scrutinizing gaze with certainty.

"Go check," He Gu stopped looking at her, and turned his head to tell Xiao An, "A man who had close contact with the deceased before his death, 30-35 years old, between 170 and 175 in height, good appearance, and a car. ”

"Yes!"

"What a team!" a police officer from the eastern district of the city suddenly ran in, "We found half a tire print on the road at the entrance of the unit! The preliminary judgment is that it is a car, I have asked, and the residents in the community who have cars have said that no one drove in or out yesterday." ”

Because the residents of the community are mainly elderly, there are not many people with cars, so it does not take much effort to investigate.

Under the admiring gaze of the police officers, Long Yi frowned thoughtfully.

After carefully investigating the scene, several people returned to the police station to continue to sort out the case.

Wei Jian walked in front, and behind him was He Gu.

"This apprentice of yours seems to be quite useful. Wei Jian glanced at Long Yi and said to He Gu.

Ryuichi rolled his eyes vaguely.

Wei Jian's thin lips curled, "Pray that your reasoning is correct, intern, otherwise the entire second team will have to pay for your irresponsible nonsense." ”

Watching him whistle and get into the first police car, the dragon smacked down and turned around and walked to the second one.

He Gu also walked to the second car, "Wei Jian is this character. ”

For He Gu, who has always been silent, this simple sentence can be regarded as comforting.

Long Yi's heart warmed, "Don't worry, Master, I won't worry about being like a nervous disorder." ”

Xiao An went back to hand over the work to Shuai Fei, and by the way, he retold the scene word for word.

"As soon as our Long Meizi's voice fell, Meng Chao from the Chengdong District Police Station rushed in, saying that he found a car wheel mark on the side of the road, but it was not left by the criminal!"

Ryuichi: ...

Who can tell her why anyone who speaks so irresponsibly can become a criminal policeman?

Shuai Fei lifted his black glasses and turned his neck in front of the computer screen with a 45° bend, "Actually, I have always had a question since I came to the police station. ”

Xiao An: "You say. ”

"Although there are few backbones of our second team, they are all elites. Needless to say, Team Tao and Team He are good at solving cases;

Da Tao is powerful, Liang Zi has an excellent memory, and I, I have not yet met an opponent in electronic tracking;

Although Long Yi is young, he is a top student in psychology.

As for you.. To this day, I don't understand why Team Tao kept you on the team. ”

There was a little silence.

"I fought Tao Xiaofei with you!"

Ryuichi covered his ears in pain.

She knew that Xiao An must have been selected because of her outstanding voice.

On the afternoon of the second day of the crime, Long Yi came to He Gu with a stack of materials.

"Master, we collected information overnight. After investigation, these three are the information of men who had a close relationship with Li Qing before his death, and they have been compared with my preliminary portrait yesterday, which is basically consistent. ”

He Gu took it and spread it out on the table.

Lin Yi, 34 years old, is the sales director of Li Qing's company. According to the description of the two colleagues, he and Li Qingren often go in and out of nearby restaurants together, and they usually flirt at work, and their relationship is ambiguous;

Zhang Chenghao, 31 years old, Li Qing's ex-boyfriend, opened a coffee shop near Li Qing's community, and the two broke up a month ago, but according to Li Qing's friends, they have been in contact since they broke up;

Fu Huiqiang, 32, is a project manager at a financial company and is currently courting Li Qing.

He Gu let out a "hmm" and quickly scanned the information, "Let Xiao An bring someone to invite all three over." ”

"Yes. ”

The first to be questioned was Lin Yi.

It was difficult for Long Yi to describe the expression he had at the moment when he heard that Li Qing had been killed, incredulous, sad, and as if there was a hint of relief.

"When?"

Xiao An: "Last night. ”

Lin Yi was stunned for a moment, and muttered: "What a good person, how can he die... What about the murderer? Has the murderer been caught?"

"Lin Yi, I called you here today to ask where you were last night! Xiao An raised his voice.

"You doubt me?!" Lin Yi was taken aback, and then smiled self-deprecatingly, "That's right, we had a big fight in the office the day before yesterday, and anyone would doubt me... But it's not me, I love her, how can I be willing to kill her. ”

Long Yi was disdainful in his heart, and reminded in a cold voice: "Mr. Lin, you already have a family. ”

"Yes, I have a wife and a son, but so what, I love Li Qing. Lin Yi covered his face, his shoulders trembled, and he seemed to be sobbing.

Xiao An: "Where were you from 23 to 1 a.m. last night?"

Lin Yi paused for a moment, "I'm playing cards." ”

In just two minutes, his voice became very hoarse.

"The specific time, who is together. ”

"With a few friends, I played from 8 p.m. to 12 a.m., after which I drove home. ”

"What time did you get home?"

"Probably a little closer, I didn't pay attention. ”

"Where are the cards played?"

"Lin'an Street, close to Jinyue International Hotel, has a chess and card room. ”

Xiao An checked, the distance from the chess and card room to Lin Yi's house was only more than ten minutes by car, "You..."

Long Yi suddenly said, "You're lying. You were in that card room yesterday, but you didn't stay until 12 o'clock in the morning. Where have you been?"

A clear female voice sounded, and everyone in the interrogation room fell silent.
