But soon the problem came again, and the other girls in the dormitory said that the girl had mental problems, and sometimes she was crazy, and the girl's words were not credible.

This really made the investigators laugh and cry.

Are Sun's words true? Is the suspect a local young man?

Later, we asked the girl's instructor, and to be honest, the girl surnamed Sun was in a stable condition and he believed that the information provided by the girl was very reliable.

Try to combine this with the information provided by our medical examiners.

I made a rough estimate of the suspect's identity.

Young people in their twenties, local youths in the community, short stature, blue cropped pants, mentally ill or physically impaired.

With more specifics, the investigation team began to conduct targeted investigations on campus.

In order not to scare people, investigators visited all the dormitories throughout the community under other names.

After the investigation, a young man surnamed Zhang entered the scope of our investigation.

The young man's height, age, and appearance are very similar to the simulated portrait of the suspect we depicted earlier.

And this boy, surnamed Zhang, according to other classmates in his dormitory, has a hobby of watching pornographic movies.

Although boys nowadays more or less have some small movies stored in their phones, other boys are just curious about these little movies.

But the boy surnamed Zhang is really obsessed.

He rarely goes out except for classes or sleeping, and after the other roommates go out, he hides in his dorm room to watch.

He had a lot of movies on his computer, which is a secret that many people knew, and the young people even nicknamed the boy the old driver.

What's even more shameful is that the boy likes to peek at the girls, and at the community pool, he can spend a day in the pool just to watch the girls swim in the pool.

Have a strong curiosity about the opposite sex.

But he doesn't have a girlfriend, and even if he had a girlfriend before, he would soon be separated.

Asked by other things why he broke up so quickly, he always said that the two didn't get along well, but his classmates always made fun of him, saying that he might not see his girlfriend.

After we met the boy surnamed Zhang, the boy went to the Internet café outside to play games.

We opened the boy's closet and found a set of clothes hanging in the closet, and the pants were cropped jeans with a beard underneath.

The clothes and pants were exactly what the witness said.

In this way, a very serious suspicion arose about Zhang, and in the subsequent questioning of his roommate, we learned another very important news.

He has had stunted growth since he was a child, and his physical examination showed dysfunction, and he was often exposed to dirt and had a great tendency to violence.

Investigators decided to take control of the young man, surnamed Zhang.

Immediately after Zhang's arrival, we conducted a surprise trial on him, but this person denied this in the interrogation room.

"I didn't kill her, I really didn't kill her......"

He looked like a mad lion, furious.

If he is not handcuffed, he may even stand up and attack the interrogator.

From this, we can see that this is a person with extreme violent tendencies.

If we want him to calm down and tell us the truth about his crimes, we're going to have to get in a bit of trouble.

We interrogated him when he committed the crime, and although he was a little angry, he couldn't tell himself.

The medical examiner examined him and found new scratches on his hands and the inside of his crotch.

For these marks on the body, the suspect could not explain how they were formed.

"The course of aggression, you can talk more carefully."

In the face of so much ironclad evidence, even if Zhang wants to deny it, it is impossible.

He lowered his head and began to explain to us: "At that time, I saw that the young woman was very beautiful, probably because he had a brain twitch and decided to start with this girl. ”

According to the suspect, on the day of the crime, he was playing near Beitan.

Just got to know the victim, and because he saw that the victim was beautiful, the suspect proposed to make friends with the victim.

At that time, the victim was in a bad mood and refused directly, which took a big hit to his self-esteem.

In anger, the suspect pinched the victim and physically harassed him.

The suspect's confession also corroborated the previous forensic inference, but the suspect's later confession aroused the suspicion of investigators.

Zhang admitted that he had done it to the victim of the crime.

But he refused to admit to killing.

"Why did you kill her?"

The interrogator asked the question again, and the suspect was angry, he slapped the table and tried to stand up: "I said I didn't kill her, I didn't kill her, why don't you believe me?" ”

Looking at the suspect's expression, it seems that he wants to prove his innocence.

The interrogator said to the suspect: "You were the only one who had the last contact with the victim at that time, and the cause of the victim's death was also directly caused by you, why do you say that you did not kill the victim?" ”

"God is looking, I really didn't kill that person, you wronged me like this, I won't admit it."

The suspect seems to be very determined, and in any case, in the eyes of others, he is a sign of denial to the end.

Looking at the suspect who denied in the interrogation room, Guapi was so angry that he slapped the table violently: "Kill someone and deny it in every way, this kind of person deserves a thousand cuts, hand him over to me, I will find a way to make him confess." ”

I reached out and pressed the angry melon peel next to me: "Let's use forensic means to let the deceased speak, we will not frame a good person, nor will we let go of any bad person." ”

According to the suspect's confession, the victim later woke up, fearing that he would be hurt again, so he desperately ran to the waterhole and ran directly into the water to take refuge.

But perhaps out of fear, the victim drowned shortly after entering the water.

Because the suspect did not understand the nature of water, he could only watch the victim drowned and did not rescue the victim.

In order to get someone else to save the victim, he hid in the woods himself, and when someone came to save the girl, he told them the location.

So that's why the staff in that community heard a cry for help in the woods, but didn't see a human figure.

Everything seemed to become clear.

Was it true that the victim jumped into the water and drowned himself out of fear?

If the victim jumps into the water and drowns, then this cannot be judged as homicide, and there will be a big difference in the sentencing of the suspect.

Mo Xiu said: "The person is already dead, maybe for this suspect, he thinks that with his words alone, the case handlers can settle this matter." ”

"You're out of forensic pathology, what can you do to get this dead man to speak?"

I looked at Mo Xiu and saw that she was confident, and I knew that this girl must have a way.

She nodded, and then said to me, "The deceased can speak, as long as I can be given enough equipment, I can let the deceased find the murderer himself." ”

I asked her, "What are you going to do?" ”

"Anything small can help the medical examiner deduce the truth of the case, and in this case, we might do a diatom experiment to get the victim to speak," Moxiu said. ”

Diatoms are single-celled plants that are too small to be seen with a microscope.

Mo Xiu said that he wanted to do a diatom experiment, so how did he do this diatom experiment?

All the case-handling personnel stared at her, because in the face of this academic problem, the other personnel were really laymen, and the saying that they specialized in the art industry was good.

Because the investigators learned from the girl's children's shoes that the victim was familiar with water.

The suspect said that the victim was drowned because he was avoiding injury, but how could a person who is familiar with the nature of water be drowned so easily?

In addition, there was neither surveillance nor eyewitnesses at the scene of the crime, so why did a girl who was familiar with the nature of the water die in the water?

Is what the suspect said true or false?

This is a problem that needs to be solved urgently in front of all case-handling personnel.

Did the victim fall into the water before his death or after his death?

When drowning and dying, there are often signs such as mushroom-shaped foam on the outside of the mouth and nose, light corpse spots, and some corpses may also have mud and sand and other water objects in their hands.

During internal dissection, watery emphysema can also be detected.

During the autopsy, the medical examiner found a little bit of sediment in the trachea.
