I replied with an "um", pinched the powder lightly at my fingertips, looked at him and said, "But how can there be such a thing in the boys' dormitory?" And it's right in the spot! That's a coincidence, right? ”

Hearing this, the director hurriedly bent down, leaned over and asked, "So do you suspect that this is a murderer's case?" ”

"I don't rule it out." I said solemnly.

When I stood up, I saw that the edge of the corridor also had some powder.

Could it be that this is a "powder killer"? Why is there so much foundation left on site?

"Could the murderer be a woman?" I asked Ye Huancheng on a whim.

The director said: "Actually, we have called up the surveillance later, but the surveillance on the other side of the corridor that day did not find that anyone came upstairs." ”

"This is the fifth floor, and if you fall down, you won't die and you'll be crippled. If there really was a second person at the time of the crime, then that person must have been the murderer, and it was a first-degree murder, not an accident. After speaking, Ye Huancheng also looked down to make sure.

I asked the director: "Did Zhou Xiaodong have any grievances with any classmates in school?" ”

"No, this kid is usually considered to be excellent in character and learning." The director affirmed.

"That's weird!" I frowned and pondered, puzzled.

In order to reconcile their contradictions, I decided to say: "Now this case is officially handed over to our city criminal investigation team for investigation, and there should be no more conflicts between the two of you, lest things become more complicated and let the fisherman benefit, you know?" ”

They both agreed.

After leaving, Ye Huancheng and I went to the local police station.

The investigators of the case indicated that it was most likely an accident, because the medical examiner had examined the body and the report said that it was an accidental death.

"Is the medical examiner's report an irreversible golden rule?" I asked.

The policeman took us to the morgue for a re-examination.

Due to refrigeration, the signs of decay of corpses are slow. The symptoms on the corpse do indicate that the deceased died of a fall on the 3rd.

But as for whether it was an accident or not? Is it artificial? There is no way to infer at this time.

This became a mystery! Even the corpses don't tell us the answer.

I opened the eyes of this corpse with my white-gloved hand and said, "The pupils of the deceased Zhou Xiaodong are completely cloudy and completely opaque. Except for multiple fractures, no suspicious findings were found on the corpse; Hands, feet, pelvis, etc., are intact, and the internal organs are also there; The cause of death was death from intracranial hemorrhage. ”

After saying that, even I breathed a long sigh of relief, feeling helpless.

Ye Huancheng suddenly came over and asked me, "When did you become so professional in autopsy?" ”

"I learned from my colleagues." I said modestly.

As I spoke, I found a strange sign: on Zhou Xiaodong's neck, there were two relatively shallow tooth marks, as if they had been bitten by something and left behind.

The two tooth marks are white next to them, and the skin is not tightened, so this should be after death.

"Ye Huancheng, come and see, the two shallow holes here, are they tooth marks?"

Ye Huancheng walked over, and after taking a closer look, he said, "It's not too obvious, I can't see it clearly." I don't think these two should be tooth marks, right? Maybe it's a pox pit. ”

I frowned, closed my eyes, and thought to myself.

Suddenly, I had a bold idea: to link this case to the case of Lin Bojun, the owner of the farm.

"Do you remember the case we just investigated?" I asked.

Ye Huancheng also thought about it, and said hurriedly: "So you mean to say that these two cases are likely to be done by the same murderer?" ”

"Yes."

"But why did the murderer do this? Sucking blood? ”

I shook my head and said, "Probably not, if it is determined to be bloodsucking, then this case will become very suspenseful, and we may be misled by the murderer." The killer must have been a person. ”

At this moment, the policeman next to us suddenly provided us with a very important clue, saying: "By the way, when we recorded a confession to a student that day, he said that the most suspicious person he had ever seen was a clown. ”

"What clown?" I immediately thought of the white powder.

After recalling it, the policeman said: "It's a clown who sells balloons in front of their school, and I thought that the student was playing tricks on me, but when you say this, I suddenly feel that that guy is indeed quite suspicious." ”

"Joker killing? Vampire? "I can't relate to it.

How can a clown kill someone who is meant to please others with his funny?

Ye Huancheng probably also felt that this case could not be investigated, so he patted me on the shoulder and said to me, "He Yang, come here." With that, he walked away, and I hurriedly followed.

"Is there something wrong?" After following to the corner, I asked.

"The case has become so complicated, and we haven't had a good rest for two days and one night," he said. Otherwise, let's go back to the city first, and let my master help think about it, he has more experience, maybe he can know who is committing the crime. I think the murderer's methods are quite sophisticated, and this may not be a first offense, so maybe my master knows such a murderer? ”

Listening to his repeated words of the master before the master, I suddenly felt bored.

Because I don't know how to open my mouth yet, tell him that Lin Zheng is actually dead, if he knows the truth, even I dare not imagine the consequences.

I used the tactic of delaying the army again, and agreed to him for the time being.

On the way back, I kept looking for a chance to talk to him, but he always told me about Lin Zheng and his past, and also talked about the case of the terrorist express, saying that it was because of that case that Lin Zheng let us know.

Actually, I remember all of these!

After returning to the city police station, I knew that paper could not contain the fire, so I found an excuse to go to the toilet to escape first, and let him uncover the truth by himself.

In the toilet, I kept splashing water on my face and rubbing my palms violently, so that my brain could clear up a little so that I could think of what to do next.

It's a pity that I thought about it for a long time, and I didn't think of any way to stabilize his emotions.

I also felt like I had been hiding here for a long time, so I moved to a big office outside.

I saw Ye Huancheng sitting alone in a position, as if he had lost his mind, sitting there, expressionless, without blinking his eyes.

I can imagine that when I walked by, he would have grabbed me by the collar and asked me why I hadn't told him earlier.
