Judging from the current traces, it is certain that the deceased's car did not leave, and the others are not known for the time being.

Ling Xiyan got into the car and waited quietly, and after a while, a group of people also came over with the collected results.

Seeing that Ling Xiyan was safe and sound, Yang Xiao also breathed a sigh of relief: "Do you have anything, do you have any other gains?" ”

Ling Xiyan handed over the photo: "I was also about to say that I saw these traces at the place where I parked." Judging from the traces, the deceased should not have left by car, Li Li, you adjust the surveillance video to see if you can find clues. ”

Checking the monitor, for Li Li, is simply a breeze, and it can be done in minutes.

It's just a little troublesome compared to people.,These have to go back to be carried out.,The tablet is still a little worse.。

They have always suspected that the deceased did not leave, and sure enough, the deceased really did not leave.

After going back, Li Li retrieved the surveillance video and compared it with the appearance of the deceased.

If traces of the deceased's entry and exit can be found, then it means that the deceased has left, and if not, it means that the deceased has been left behind. There is basically no doubt who left the deceased behind, it must be the murderer.

After Li Li retrieved the surveillance, he made a comparison, but did not find a suitable image, only entered.

Of course, if it's a little later, you can't see anything, and even if it's someone, you can't use it at all.

On top of that, the surveillance only has some images, and there is no sound, so there is no way to compare.

There is no image, no sound, and it is more difficult to find someone than to climb to the sky, and now I can only see the autopsy.

The traces of the scene are very messy, after all, it is a classroom, and there are many students and teachers who usually come and go.

In this place, the traces found are very messy, and the fingerprint coverage is also very large, and they are all very unclear. There is nothing they can do about this aspect of the problem, and what Yang Yao found at the scene is basically useless.

Judging from the traces around the deceased, the deceased's death lasted for a long time, but the murderer did not touch much.

The things around are basically still very messy, and the tables, chairs, benches, etc., are all placed randomly.

Ling Xiyan rubbed his legs, the air conditioner is uncomfortable to use, and it is even more uncomfortable if you don't use it.

Li Li hurriedly took the Xia Liang quilt: "Cover it a little, blowing like this is not good for the bones." ”

It's not too cold to cover this, Ling Xiyan sighed: "What do you say I can do now?" I can't stand the cold. In the past, even if it was a snowy day, I didn't feel anything when I was alone. ”

Yang Xiao, who was next to him, tucked the corners of the quilt: "Recuperation is no better than anything else, I'll go and see if the results come out." ”

Before Yang Xiao passed, the black purple over here?? Turbulent rice? Chivalrous poke and play?? Heartfelt chewing Cong Jiao Jiao forgiveness

Although it took several hours, it was relatively fast, and many experimental results had to wait.

The autopsy results were handed to everyone: "Let's take a look first, the situation of the deceased is more obvious, the cause of death of the deceased is excessive blood loss, mixed cardiopulmonary failure, and excessive pain leading to death. Of course, there were many wounds of the deceased, and according to the condition of the wounds, there were more wounds caused before the death of the deceased. In the blood of the deceased, I checked for some medicinal ingredients that made the deceased unable to wake up. ”

The deceased could not have fallen asleep in the classroom, then the place must have been, and others would not have gone there, but this place should have been known to the murderer. The murderer also brought people out of there in the dead of night.

No signs of another person were found on the deceased's body, but the struggle was evident.

The deceased had no other diseases, was in good health, and did not have any drug reactions or the like.

There were no traces of drag on the corpse, and Li Cang's first place of death should be the classroom where the crime occurred.

It just so happens that Li Cang is a creature who teaches this class, so Li Cang is placed here, probably a kind of demonstration. It is very likely that this person wants Li Cang's death to serve as a warning to someone.

Or think that since Li Cang is the biology teacher of this class, it is best to die in this class.

It is also possible that this class is associated with someone or a grudge, and the murderer chooses it this way.

It certainly can't be because, the murderer thinks, what a good thing living things are, otherwise it wouldn't be put together with death.

As for choosing a location, the teacher is actually the best place because it's big enough and the soundproofing is good.

Anyway, there must be a reason for putting this person here, and the reasons are very complicated. These biology topics made Ling Xiyan have some interest, and she took them and looked at them for a while, she left school too early, and she really didn't remember some things.

Although I am only 20 years old, the time to leave school and learn new things is still closer.

These biological topics, Ling Xiyan looked really unfamiliar, but Yang Xiao could still make some.

"It's all difficult, and the answers to many questions are probably only known by good students."

Ling Xiyan tilted his head: "Did you just say that you are a good student?" Do you find these questions difficult? ”

Yang Xiaoleng paused: "Yes, but it may be that I have been away for a long time, maybe they have changed the textbook." What are you doing all of a sudden? Did you think of something? Puzzles, or are good students inspiring you? ”

Ling Xiyan still remembered the content of the previous conversation clearly, Li Cang liked good students.

So is it possible that some of the students who had been taught by Li Cang in the past came back to seek revenge from Li Cang?

Maybe these days, it's not going to be good, so I choose to come back to him for revenge and let him know himself.

Ling Xiyan asked Li Li to investigate, and there were actually a lot of students taught by Li Cang.

After all, Li Cang has also been a teacher for several years, and he teaches biology, so naturally there are many students. But when it comes to these students, in fact, many of them have been blamed by him, and only the kind of students whose grades are particularly good and very stable have no impact.

It's not surprising to say that there are really students who hate it, but isn't it too serious to come back for revenge after graduation?

How much resentment, even after graduation, to come back and kill? And the resentment of learning is not enough, right?

It's this resentment, or the motive, that they feel quite entangled, after all, it's the death of a teacher.

If it is because of learning that students do it, then just because of learning, it will not kill anyone. But if it is said that the teacher did it, and the teachers are between them, how many conflicts of interest must there be before such a decision can be made?
