“When I was in the police academy, I learned Lokar’s law of material exchange, but whenever a crime is committed, there must be direct or indirect traces left at the scene.”

Walking out of the warehouse, Xiao Yu stared at Guo Qiang, who had a blank face, “Master, there is no trace of murder in the warehouse, at most it is only the second scene of the abandoned body.” ”

“Worthy of being the number one genius in the police academy’s graduation grades.”

Guo Qiang was convinced, “In the face of people like you, I have the feeling that I have come to the world just to make up the numbers.” ”

No, I’m not that good, I’m just a smart porter from my past life… Xiao Yu grinned, “Master is too prestigious, my experience is not enough, I will definitely follow you to learn.” ”

Psychology said: Don’t treat me like a fool anymore, test the new set of people, please don’t use it on me, waste time!

As he thought.

Guo Qiang took Xiao Yu to the warehouse, did not tell him that it was the scene of the abandoned body, and indeed wanted to test this new apprentice.

As a result, the apprentice was too strong, and turned his old face as a master over and dropped the past pump.

I almost couldn’t hang my face.

Angry?

No, Guo Qiang was a little happy.

Xiao Yu’s talent, every case-handling unit likes it, breaking his head and rushing to get it.

The more talented you are, the easier it is to achieve results in the future.

The criminal investigation brigade is a collective, and anyone who makes achievements can follow the light.

On the other hand, if the case cannot be solved, the whole brigade will be unlucky…

Guo Qiang did not play ‘flower work’ again.

He was sure that Xiao Yu might be inexperienced, but his ability to investigate cases was excessive.

Playing with others to test that set is to live with your old face

……

The first scene of the crime, the factory dormitory.

A small three-storey building.

Dining room on the first floor, men’s bed on the second floor, women’s bed on the third floor.

The so-called first scene is on the roof of the building.

Crouching on the ground, staring at the black and purple blood everywhere after the air dried, Xiao Yu narrowed his eyes.

Such a scene is right!

First of all, you can see the traces of the victim’s struggle after falling to the ground, and you can see some footprints.

Observation through the scene, as well as the traces left behind by the victim’s body after it fell.

Behind the attack?

Because when the body died, it was facing down.

From the friction marks of the head on the ground, and the direction of the blood spray.

It was after falling, and then suffered continuous heavy blows.

Judging from the fact that the victim could not even reflexively do this, the murderer was extremely fierce and murderous.

First the victim is knocked down, then continuously, without giving a chance to react.

Extrapolating from a psychological point of view, there are not many ordinary people who can do this.

It can make a person burst out with such a fierce mentality, cruel killing.

There are no more than five categories: feelings, resentment, interests, jealousy, greed!

Killing people for no reason?

It doesn’t exist, it’s psychosis!

Over and over again surveying, over and over again, over and over again.

Unconsciously, Xiao Yu entered a certain state.

Until…… He looked up and shook his head helplessly.

There was not much to discover at the scene.

Xiao Yuxin said: I can’t walk this road for the time being, so I will change my thinking and break through from other places.

Blind date in the morning, report at noon, go to see the scene of the case in the afternoon, and it is already five o’clock when I return to the brigade.

I called my family and said that I would report to the unit and would be back later.

As a result, his mother scolded him at that time.

What to say: You and your Aunt Zhou’s girlfriend didn’t say two words, and you left with a woman? How do you ask me to explain to your Aunt Zhou, you little cub waiting for me, waiting for you to see the old lady not to pick your skin…

).

Xiao Yu, who was sweating profusely, ended the call with his mother.

In the past, he always believed that the tigress was the most terrifying creature in the world.

After crossing, he found that he was wrong and sloppy.

When the tigress upgrades the mother, you will understand what the real ferocity is!

There were four gasps in the house, ranked by status.

Mom, Carla, Dad, himself.

Carla is a dog!

Thus.

Carla is the one who gave birth, the father picked it up, and he sent it with a charge of phone bills….

Perfect!

……

Criminal Investigation Brigade.

Xiao Yu was sitting in a chair holding a folder, which contained the case file of the murder case in the warehouse.

Rather than site surveys, he prefers to peel back the cocoon on the file.

Chew on the subtle details and then make up your mind.

The so-called search for clues is nothing more than two words, reasoning.

The most important thing in reasoning is to do subtraction.

Sort out the clues one by one.

Otherwise, it is a yarn ball, and it will only become more and more chaotic the more you think about it….

At this time, Xiao Yu was reading the autopsy report.

“The victim’s posterior skull was hit by seven gravity blows of suspected metal objects, resulting in a fragmented brain bone…”

When tasting the file, Xiao Yu’s arm was unconsciously raised and waved at the air.

Once, twice, three times… Up to seven times.

Blinking, Xiao Yu, who had returned to the gods, could be sure.

There was only one murderer who killed the victim, but it was impossible to judge whether there was any accomplice assistance.

At the time of the crime, the factory was on annual leave, and only a dozen employees did not return for the New Year.

Among them are two female employees, who are also the main suspects in this case.

Why are these two women the most suspicious?

Extrapolating from the time of death by autopsy, the victim died four days ago, probably in the middle of the night.

At that time, only two female employees were in the dormitory, and other employees were working overtime in the factory, and the opportunity to commit crimes was not large.

Paradoxically, through the autopsy, the murderer swung the murder weapon and smashed the victim’s skull, which is difficult for ordinary women to do.

Not to mention, the average woman rarely has this psychological quality when committing crimes.

But there are not many women involved in indirect, participatory, active, murderous killings.

There are authoritative experts through the historical investigation of cases, the ratio is 9 to 1, which is the real data.

Female offenders who use blunt weapons to kill people are even fewer.

That is to say, it simply refers to the use of blunt weapons to commit murder.

This is not a girl’s strong point!

Of course, Xiao Yu thought that his mother was the exception.

When I was a child, when I watched my mother beat my father, I was proficient in all kinds of martial arts in the eighteen classes, and I was proficient in all kinds of weapons.

Press Dad to the ground and rub it every minute.

A ferocious horse!
