For example, the case of a female college student who was killed and burned by the river on the campus of the university. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Tonghai University is located in the southwest of the city center, and there is a small stream called the Jindong River that runs through the city in an east-west direction, and also flows through the campus area of Tonghai University. The green belt on both sides of the river is very beautiful, especially the empty and thick green meadows, which attract men and women and young people to come to play or give directions. When night falls, the grass by the river is full of young college students. Not to mention that in early autumn, no one cares about the rows of tall willow trees falling down the river, and even college students may think that these leaves bring them a ghostly beauty and dreams. Indeed, these colorful leaves falling on the yellowed dead grass are even more "dyed". And the cool autumn breeze just washed away the summer heat that had just passed, so college students often talked or were intimate on the grass late at night.

No one expected that there would be murder and arson in such a place.

The fact that a criminal dared to strangle a beautiful senior girl on the grass on the bank of the Jindong River between the two campuses of a university and then burn the body can only show that the criminal is the deceased: an acquaintance, and his actions point to murder with passion.

acquaintances, so that the female college student followed the suspect to the riverside grass without any guilt.

Murder of passion is because the suspect did not think of putting the person to death in advance, so after strangling the person, he used local materials and used withered grass and yellow leaves as a weapon to bury the evidence of the crime to burn the body.

To be clear about the place where he committed the crime, on the other side of the river is an apartment building for a female student in the Faculty of Letters. Ping Shu analyzed: As long as the female college students have been in contact with the people in the past one or two days, it is very likely to find suspicious people.

The woman's body was found by a university janitor. Because she had to clean the campus area assigned to her at 5 a.m. every morning. She had finished sweeping the road, and the sky was already faintly bright, and she saw that there were traces of burning in the meadow. She went out into the grass, and she saw the body of a girl dressed up, her head apparently burned beyond recognition. She shouted, and the female college students opposite immediately ran over one after another, and they testified one by one that the female corpse whose head was burned should be Hu Yang, a senior girl living in room 314 on the third floor.

Hu Yang is a beautiful female college student who can sing and dance, and is talented in writing, from a county under Tonghai City, and her father is the secretary of the county party committee of that county. Not to mention the teachers and students of the Faculty of Arts, even the male college students in the Faculty of Science, Engineering, Computer Science and other colleges know that Hu Yang is a school flower, but she has not been selected and has not been recognized by the public election.

However, room 314 and even all the teachers and students who were asked said in unison that Hu Yang had no boyfriend at all, and she had never been in love.

The investigation at the scene showed that Hu Yang was wearing a pure white dress and a black fine wool cardigan, which had been burned by the fire and was dirty and damaged, but basically he could still cover his body. Her long shawl hair was said to have been largely burned, her eyebrows and eyelashes were gone, and her eyes were most burned, but her nose, chin, mouth, and face were faintly visible. There were still piles of weeds and leaves gathered around him, but for some reason they didn't ignite.

Forensic doctor Xiao Xiao said: "I analyzed, the girl died of suffocation, look, there are traces of being stuck in her neck." It was burned after death. There should be no sexual assault before or after death. But it needs to be checked in detail by going back to the technical investigation laboratory. ”

Ping Wei asked: "Why did the criminals choose to commit crimes here? Why was the girl's body burned only for her face? Xiao Xiao, do you say, was the wind too light last night, the leaves and dead grass could not be completely burned, and the flames were forced to be extinguished?

Xiao Xiao smiled and said, it should be like this, fortunately, the girl's body was preserved, otherwise we would have to waste enough time just to find the source of the corpse. However, we still need to go to the Meteorological Bureau to check the weather last night.

Ping Fu said: "Xiao Xiao, you say, why do criminals burn their eyes first? Is it because they are afraid of the so-called legends that are prevalent?"

Forensic doctor Xiao Xiao said: "I think it's very likely, hehe." ”

Ping Wei knows that there is a movie "White Snake Murder" directed by Li now, which is in full swing. In the movie, it is said that the eyes of the deceased will leave the image of the last criminal. This is a fact that the literati took for granted and did not actually exist.

In that movie, the key piece of evidence to identify the killer was a photograph of the victim. This photograph was obtained through a peculiar physical evidence technique. This physical evidence technique is to take a picture of the pupils of a deceased victim, so that the last image of the victim before his death is fixed with a photograph.

In fact, this physical evidence technology is only the imagination of the novelist, and does not exist in real life.

Because the principle of human eye imaging is similar to that of a digital camera, the eye is equivalent to the lens of a camera, and the negative is a bioelectrical impulse transmitted through the optic nerve, these things can only be recognized by us after the brain interprets them, and we cannot directly form an image with our naked eyes.

Therefore, it is impossible to obtain the final image of a deceased victim by taking a picture of his or her pupils.

If we want to know the last image of a deceased victim before death, we can't do that unless we can directly crack the biological signals that the optic nerve sends to the brain, which is not possible with current science and technology.

However, this impossible evidence is the only evidence depicted in the film. In addition, the plot of the investigation of the "Silver Snake Murder Case" has not been fully demonstrated. In this way, not only can the police interact with the serial killer in the process of advancing the investigation activities, making it difficult for their image to be blurred and gradually change to clear, but also leads to the fact that the chain of evidence to identify the murderer is completely incomplete, and there is great suspicion, making the outcome of the murder case very abrupt.

This is how Ping Wei felt after watching the film, but he never expected that there would be criminals to follow suit. In other words, it is highly likely that the criminal in this case was worried that he would be followed by the murder of the dead girl's eyes, so he took the scene to burn the body to destroy the possible evidence.

In this way, Ping Yu decided to track down the whereabouts of female college student Hu Yang on the last day of her life as a breakthrough to find the real culprit.

Sure enough, a male college student named Fei Hua, who had just graduated from college - a fellow of the senior girl Hu Yang, surfaced.

When Ping Yu and the young men of the criminal police hurried to his hometown, he happened to meet Fei Hua who had just returned home to see his parents and was about to abscond, but he was arrested under the big tree at the entrance of the village.

As soon as Fei Hua heard that it was from the Tonghai City Criminal Police Brigade, he immediately turned around and escaped, and was naturally quickly taken down by the well-trained criminal police boys.

In the van on the return trip, Fei Hua confessed the facts of the crime.

It turned out that his motive for killing was to beg his fellow female villager Hu Yang to help him find a teaching job in a middle school, and after being rejected and despised, he killed with passion!

The motive for the cremation of the corpse is really because I have just watched the movie "The Murder of the White Snake".
