"The face is bruised and swollen, the eye conjunctiva has needle-shaped bleeding points, the oral mucosa is also damaged, and the neck is also damaged. The chest injury is mainly concentrated in the breast, accompanied by epidermal loss and subcutaneous bleeding."

In Beitan, a school worker found a female drowning person, a young woman, who seemed to be a student in the school.

The forensic doctor is performing an autopsy on the deceased.

When we arrived, the young deceased had been dead for a long time. After urgent communication with the family, the police decided to conduct an autopsy on the deceased first and then finally determine the cause of death.

That forensic doctor showed the body's surface to be examined.

He said: "Black-shaped scraping can be seen around the head, and no obvious open damage can be seen in other parts of the body. Judging from the surface of the body, the girl suffered from mouth covering and neck choking during her lifetime. Now it can be preliminarily concluded that this is a homicide case."

Is it another homicide?

The atmosphere at the scene suddenly became tense.

If this is another homicide against a female student, then this is simply a provocation to the police.

After a series of cases occurred in the school, a large number of police officers had entered the school, although the school’s Beitan was seven or eight hundred meters away from the west district.

But no matter what, this is within the campus, which is equivalent to killing people under the nose of the police. If this murder case is established, it will give the police a warning.

I took a deep breath.

Because of this corpse, as well as the bodies of our three colleagues who died in the line of duty, Gao Wei has now rushed to the Forest Park to deal with the affairs of the three colleagues.

I took Ou Ye to Beitan to the school, thinking that this was just a simple case of student drowning, but I didn't expect that it would be another murder case.

My scalp is almost numb.

Ou Ye said to the forensic doctor: "Can you confirm that it is a murder case just from the surface of the corpse? The reaction on the surface of the corpse can only indicate that the deceased was attacked before his death. The cause of the deceased's death should not be an attack to death, right?"

This is Ou Ye’s suspicion.

The forensic doctor looked at Ou Ye and continued: "Based on the manifestation of the corpse, the deceased may have been sexually assaulted during his lifetime."

Ou Ye turned around and looked at me, as if he had something to say to me, but it was a little difficult to speak. I looked at Ou Ye's expression, then looked up and looked at this Beitan.

There are two artificial lakes in this normal university.

Near the south gate is a relatively small artificial lake. There are some water lilies and other places in the artificial lake. It is called Nantan by students, about two or three hundred meters away from Nantan. It is behind the school’s library, and there is a relatively large lake. There are several swans in this lake. This location is the most desolate place in the entire school and is called Beitan by students.

Because the lake in Beitan is relatively deep, students often drown.

Therefore, the school specially arranged for school workers to patrol to prevent students from getting close to the water in the pond. First, protect the swans in the pond, and second, prevent students from falling into the pond.

After the body was transported away, we and other criminal investigators conducted a comprehensive investigation of the crime scene.

Soon, surveyors found a string of falling beads on the grass beside the water.

On the other side of the pool, another pair of glasses and shoes were found.

After being identified by the victim's classmates and family members, these were worn by the deceased during his lifetime.

At the same time, we made major discoveries.

"The soil has fresh signs of turning, and the grass has fallen down."

Ou Ye squatted down and looked at the grass by the pool. Because she saw a messy place, she called me over.

Judging from the traces of the scene, this place has experienced a fight.

Because this is only achieved in the case of fierce fighting, and this kind of fighting is not an ordinary fighting method. It should be one-sided and powerful force bullies a weak person.

I looked at the traces on the ground, gritted my teeth and said, "Obviously, these traces are traces of dragging. Looking at these traces, this is definitely artificial."

"What kind of thing happened to this girl? Are there any surveillance nearby?"

Another colleague next to us asked this question. We looked up and looked around and found that there was really no surveillance probe nearby.

At this moment, we found a few strands of falling fibers on the lodged grass leaves.

However, we are not sure whether these shed fibers are related to this case.

When visiting the deceased's classmates, the investigators also obtained a very important clue.

At that time, the girl had a little conflict with the girl in the same dormitory. Maybe because she couldn't think so, she walked out of the dormitory and wandered around the campus alone.

The victim went out to play in anger and did not go with other classmates and besties. It was because of this action that the criminals had an opportunity to take advantage of.

When it was time for dinner, the victim had not returned to the dormitory. When the classmates were about to go out to find her, a school worker found her body.

We asked the school worker who found the body.

According to his recollection, he was patrolling the pool alone. When he was patrolling a small bridge, he heard someone shouting across the pool, and the person said that the body was found in the water.

When he arrived at the other side, he found that there was no one on the other side, but there were really bodies in the water. He didn't think much about it at the time and called the police directly.

I asked the school worker: "Is the person who called you at that time a man or a woman?"

"It should be a man."

The school worker still recalled a little bit of lingering fear, Ou Ye said: "Do you see clearly what he looks like? Can you know how old he is?"

"I don't know, I didn't see clearly at all. I thought it was a ghost calling me."

The school worker looked pale and looked very scared, which was very easy to understand. When someone called him that he had found a corpse and ran to the corpse and found that there was no one, no one would be scared in this situation.

The school worker said that the girl had already floated on the water at that time, and he didn't think much about it, but just called the police over.

But who is the person hiding in the woods?

How could this person know where the victim is?

Is the person who makes the sound a suspect or an eyewitness?

Now we know that no matter whether the person hiding in the woods is a murderer or a witness, as long as this person can be found, it should be the key to solving the case.

The question is that the school is so big, where should we find this person?

However, after some visits, we did not find this person in the school. Another group of visitors learned that the victim's father was the head of an important project and had the right to decide this large amount of funds. The social relationship was very complicated. Will this have something to do with the death of his daughter?

But can people in the society go into the school to kill people?

Ou Ye said: "I think we should let the corpse speak, perhaps the real clue is the body of the deceased itself."

Soon, we conducted a further autopsy on the deceased.

This autopsy was performed by Ou Ye. Perhaps for Ou Ye, this is the first time she has actually performed an autopsy since she became a police officer, and it is also a milestone for her.

"The oral mucosa is bleeding, and there is a little mud and sand inside the trachea..."

At the dissection site, Ou Ye picked up the knife and slowly cut the dead body open, and the autopsy officially began.

"Due to bleeding, medial epidermal abrasions, secretions were extracted for testing!"

In cases where this involves indecent molestation, the suspect's body fluid is usually left behind in the body of the deceased.

Through DNA testing in body fluids, the suspect can be quickly identified. We also hope to extract secretions and pull the suspect out of the darkness.

However, after secretion tests, we did not find out the components of male body fluids.

All the staff were confused.

If this is a murder case caused by sexual assault, why is there no male body fluid? Without this thing, it can only mean one problem: this kind of thing has not happened or has not succeeded after it happened.

Anyone has doubts about this result.

Ou Ye asked me: "I can't understand one thing. Since the victim's body has been hurt and the fact that he was sexually assaulted has happened, why is there no male body fluid in his body? Is the perpetrator still wearing a condom to commit the crime?"

Any sexual assaulter, what they do is accidental, and it is impossible to prepare a condom in advance.

I thought about it and said to Ou Ye: "Is there another possibility that this suspect has sexual dysfunction."

If a person has sexual dysfunction, he will definitely not be able to enter the victim's body, but he can harm the victim, and this kind of damage may be greater than the damage caused by sexual assault.

But so far, all of this is just a speculation.

We must visit the witness again and draw a little answer from the witness's mouth.

We asked the school worker who discovered the deceased again: "When you discovered the victim, were the victim's clothes intact?"

"Yes, I'm sure of this."

The school worker nodded and replied that I exchanged glances with Ou Ye. Ou Ye said, "But according to our understanding, the victim was abused at that time. After being abused, a woman would not be able to wear her clothes and pants by herself in such a panic."

Hearing us say this, the school worker lowered his head in shame.

His expression became very awkward. He thought for a while, then blushed and said to us: "Actually, I helped the little girl put on her pants. Because I saw her pants retreated at that time, I was afraid that others would misunderstand me, so I helped her put on her pants."

This school worker is a little strange. Why do others misunderstand him? What are he worried about in his heart?

I asked: "Where did the victim's pants retreat at that time?"

The school worker gestured and at the base of the thigh, that is, the victim's pants were only slightly backed. If the school worker said it was correct, the suspect's organs could not contact the organs of the deceased and could not complete the substantial invasion.

This further confirms my speculation that the suspect must be a dysfunctional person.

After the school worker left, Ou Ye's face turned red: "It's hard to imagine that I, a little girl, and you two big men, are here to talk about such shameful things."

"You'd better get used to it slowly, and then there are many perverted things."
