Chapter 43 Case Analysis (please collect and vote for me)
At 08:30, the criminal police team arrived at the crime scene, in the back mountain of Wuyi Town.

The scene has been cordoned off by police officers from the police station who arrived in advance.

In the mulberry leaf field, the deceased wearing a black upper body suit was lying on his back. The corpse was already smelly. There was a swarm of flies and mosquitoes on the corpse. What was frightening was the face of the deceased. The original three-dimensional face had been transformed beyond recognition. It's flat, with a swarm of flies squatting on it.

"The murderer destroyed the face of the deceased, either because he was worried that the identity of the deceased would be recognized, or because he had a lot of grudges with the deceased, or both, but the most likely reason is that the murderer did not want people to recognize the identity of the deceased." Luo Fei Standing nearby, observing the corpse, he secretly speculated.

Then Luo Fei noticed a pool of blood on the grass next to the body, and the grass also had signs of being pressed. Luo Fei suspected that the body had been moved.

Zhao Donglai obviously also noticed the traces of the body being moved, and his expression instantly became ugly.

The director of the Wuyi Town Police Station, a fat man with a big belly, came over with a smile on his face and said, "Captain Zhao, you are here. I have ordered the people below to protect the scene."

Zhao Donglai suppressed the emotions in his heart and asked in a low voice: "Director Liu, has the body been moved?"

Hearing this, the pot-bellied director suddenly showed an embarrassed look on his face, and whispered: "The people down there are not sensible. When I came up, I didn't pay attention, and they moved the body. They said they wanted to identify the body. I have been ruthless." criticized them."

Now that the matter has come to this, Zhao Donglai can do nothing even if he is angry again.

The villagers who found the body were called to learn more about the situation.

"Everyone, please check around to see if there are any useful clues. People from the technical room will investigate the scene and examine the body." Zhao Donglai first ordered people to search around to see if anything can be found, and then asked people from the technical room to Survey the site.

Luo Fei also followed the others to search everywhere. Soon, the second group found a bloody stone not far away. Judging from the blood stains on the stone, it should be one of the murder weapons used by the murderer.

After searching for half an hour, nothing was found. Luo Fei and the others returned to the body. At this time, Yang Mei and the others also completed the on-site investigation and autopsy.

"The deceased was a man, about 50 years old, 178cm tall. The time of death should be about 48 hours. There were three stab wounds on the deceased, all on the lower back. The face was completely injured, making it impossible to identify the deceased's appearance. There were also wounds on the deceased. There is no object that can prove the identity of the deceased. It is suspected that the murderer took it away. No fingerprints, footprints or other traces left by the suspect were found at the scene." Yang Meihui reported.

"What's the cause of death?" Zhao Donglai asked with a frown.

"This cannot be determined at the moment. We have to wait for forensic identification before we can draw a conclusion, because whether it is a stab wound on the lower back or a smash on the face, it may be fatal."

"Were there no fingerprints found on the stone you just found?" Zhao Donglai continued to ask with a frown.

"There are no complete fingerprints to extract." Yang Mei shook her head.

Zhao Donglai frowned, then looked at everyone and asked: "Let me know what you think." "Obviously, this was probably committed by an acquaintance. The murderer was probably afraid that the identity of the deceased would be exposed. The police found him based on the deceased's social relations, so he destroyed it. They also took away all the objects from the deceased that could prove the identity of the deceased, making it impossible for the police to identify the deceased." Yang Su was the first to analyze.

Hearing Yang Su's words, Zhao Donglai nodded, "There's more, continue."

Yang Su thought for a while and continued: "The murderer should be a male, and he is physically strong. One knife made the deceased lose his ability to resist. Otherwise, it would be impossible to kill the deceased so easily."

Yang Mei continued what Yang Su said: "I also agree with what Team Leader Yang said. The murderer should be a male. The knife wounds on the deceased's body were from bottom to top, which means the murderer should hold the knife in an upright position, like this." Yang Mei made a gesture of holding the knife, and then continued: "If you want to kill the murderer by holding the knife in this way, there are two prerequisites. One is that the murderer is strong enough, and the other is that the murderer must be about the same height as the deceased. In this way, the murderer must be In order to better exert force, and from the location of the wound on the deceased, it can be inferred that the murderer should be about the same height as the deceased. Based on the two circumstances, the murderer should be a man about the same height as the deceased. "

Luo Fei also thinks that the murderer is a male, but the most important thing at the moment is to find out the identity of the deceased first. Only when the identity of the deceased is clear can they continue the investigation.

Zhao Donglai asked if anyone had anything to say. Seeing that no one spoke, Zhao Donglai said: "Then I will tell you my views on the following investigation."

"First of all, the most important task at the moment is to find out the identity of the deceased. Only by understanding the identity of the deceased can we further conduct a more targeted investigation."

"So in order to find out the identity of the victim, I will now arrange a task. A group will be responsible for visiting nearby villages to see if there are any missing persons."

"The second and third groups are responsible for going to various police stations to check the missing persons reports in the past half month, and check one by one to see if the deceased is included in the missing persons report."

"People in the technical room collect the DNA of the deceased to see if matching DNA can be found in the DNA library; if possible, let the forensic doctor help to see if the deceased's appearance can be restored."

"My idea is this. If you have any good ideas, please talk about them. Speak freely. Whether they are good or bad, speak them out and brainstorm."

Luo Fei looked at it and waited for a while. Seeing that no one spoke, he raised his hand to answer.

"Say"

Luo Fei then said: "As for the identity of the deceased, I think the deceased may be from Ningjiang County, or more likely not from Ningjiang County. If the deceased is from Ningjiang County, then I think the murderer tried his best to destroy the deceased. In fact, the face of the deceased does not mean much. Unless the deceased has no relatives or friends, usually alone, and no one cares about him after he dies, otherwise even if the murderer destroys the face of the deceased, the police can still find out the identity of the deceased. Spend more time.”

"So I suspect that the deceased is probably not from Ningjiang County. In this case, if the murderer destroyed the face of the deceased, it will be very difficult for the police to find out the identity of the deceased."

"Captain Zhao, I have an idea. If the deceased is not from Ningjiang County, then he is most likely staying in the hotel, and the deceased and the murderer ran to Wuyi Mountain, which means that the deceased has no plans to leave Ningjiang County yet. , so my idea is to check the hotels in Ningjiang County to see if they have checked in, but there have been no guests in the past two days."
