If the identity of the deceased can be determined in Nangang Village, it will be relatively easy to solve the case. The murderer might be someone from Nangang Village who chose to dump the body nearby.
But now that the identity of the deceased has not been determined, we can only wait for the ingredients to be fished out tomorrow for DNA comparison.
Early the next morning, Lu Chuan and others rushed to the scene in Nangang Village.
Because we have been digging all afternoon yesterday, everyone is already used to this kind of thing, so the progress of today's work is relatively faster.
As the deputy director in charge of administration, Lu Chuan certainly couldn't watch everyone go down. In the meantime, he also went down into the reservoir.
By around 3 p.m., the water in the reservoir had basically been drained.
All that's left is to get the bones out.
After all the water is drained, the entire ribs are exposed.
Some skeletal parts can be taken out in one piece, but some have been scattered in the mud. Fortunately, we have taken photos and recorded videos with instruments, so we can completely restore the shape of the bones.
The entire excavation work went relatively smoothly. Han Guo had been sent to the Criminal Police Brigade at around 7 p.m.
Lu Chuan personally presided over the identification and analysis of the skeletons.
The first step is to extract the DNA information of the skeleton. It would be best if the identity could be compared in the information database.
Of course, this may be relatively small.
When the skeleton was taken out, the outer clothing was not completely rotten.
The lower body is denim shorts and the upper body is printed short sleeves.
"Based on the child's clothes, it can be determined that the time of death of the victim was summer."
On Lu Chuan's inspection, the forensic doctor from the Criminal Police Brigade began to take notes.
“There are traces of blunt force blows on the front of the skull.”
Lu Chuan picked up the skull among the corpses and looked carefully. There were obvious blunt force blows above the right eye of the skull. Traces leading to skull fractures.
The marks of blunt instrument impact discovered by Lu Chuan were very serious, causing the internal collapse of the skull, which should be the main cause of the victim's death.
Of course, because these are skeletons, the cause of death of the deceased cannot be completely determined, and we can only make auxiliary judgments.
“Judging from the degree of tooth wear, the deceased was approximately between 25 and 28 years old. The pelvis was narrow and there were no birthmarks. The deceased had no history of childbirth.”
“Height… …158…”
In addition, the skeleton also wore a pair of sandals on its feet.
Lu Chuan carefully studied the wear and tear of the sandals.
The material of the sandals is entirely plastic.
Judging from the style, they should be sandals from a few years ago.
Judging from the degree of wear and tear, there are about two to three years of wear and tear.
The identification and analysis of the skeletons was relatively fast. In less than two hours, Lu Chuan should have gotten some clues.
In the conference room, Lu Chuan was arranging and deploying the investigation of missing persons.
"The deceased was a female, 1.58 meters tall, aged between 25 and 28 years old."
"Before her death, she was wearing a denim short skirt on her lower body and a printed short-sleeved upper body."
"The time of death was estimated three years ago."
In fact, it is not easy to estimate the time of death of the deceased.
The different natural environments of corpses have great differences in the time of skeletonization.
Lu Chuan could only make a rough estimate of the time based on the soaking condition of his clothes and the wear and tear of his sandals.
The next task is to make every effort to confirm the identity of the deceased. Lu Chuan then returned to the forensic office to continue research.
From the current point of view, skull trauma should be the main reason for the death of the deceased.
“Bureau Lu, what have you discovered?”
The forensic doctor of the Criminal Police Brigade discovered that Lu Chuan had been observing the scars on the skull.
Lu Chuan nodded: "There is a little clue, mainly the location of the scar."
Lu Chuan pointed to the scar on the skull: "The scar on the skull was caused by a blunt instrument. From Judging from the fine cracks and debris, they are probably objects such as stones."
"Also, look at the location of the scars."
The forensic doctor came to observe and the location of the scars was concentrated. Above the right eye, roughly at the top of the head.
"Generally speaking, if two people are fighting together and hitting the face with a hammer, it is likely to cause skull injuries on the back of the head or the front."
Lu Chuan gently stroked the scars on the skull: "But this The location of the scar is on the top of the head. What position of beating will cause injury in this position?"
The forensic doctor frowned and stretched out his hand to gesture...
"It should be the back, a sneak attack from the back, and the opponent was attacked from the back. He was relatively tall, so he could inflict damage on the head of the deceased at this angle!"
The forensic doctor then realized that Lu Chuan had originally analyzed the location of the scars on the skeleton and restored some details of the victim's scene.
"Yes, the victim is 1.58 meters tall. After putting on the shoes, he is about 1.6 meters tall. And this mark should be that the murderer attacked from behind."
After Lu Chuan looked carefully, he stood up and simulated coming from behind. The attack from behind.
Then he asked: "Under what circumstances would the victim be attacked from behind without being alert or resisting?"
The forensic doctor blurted out: "A familiar person! He must be a very familiar person!"< br>
Lu Chuan nodded in approval.
This is the judgment.
Not only that, Lu Chuan could tell from the injuries on the victim that the murderer was about 1.8 meters tall.
Only the murderer could have caused such scars at this height.
Of course, it is not ruled out that the murderer is shorter, but he stood on a high platform and attacked.
It’s just that this possibility is relatively small.
In addition, Lu Chuan believes that there is a high probability that the crime scene will be the first scene.
The reason for making this judgment is that the deceased was in a head-down position, and the impact caused the cervical vertebrae to break, so the skull floated up.
Of course, this is just a guess. Lu Chuan and others have also conducted surveys around the discovery site, but found nothing.
Some stones were recovered from the surroundings. After comparison, it was found that the shapes of these stones did not correspond to the skull injuries of the deceased.
It may be that the murderer picked up the stone, because his fingerprints may be left on it, or it may be that nearby villagers picked it up.
It is possible that Wang Zhaokai and others learned this when they visited the villagers in Nangang Village.
The pond is not far from the village. There are many stones around it. When the villagers build houses, they sometimes pick up these stones.
"In addition, look at the impact marks of this wound. It is an impact from left to right."
The marks of the wound can tell from which direction it was invaded.
“The impact marks of these dozen broken trees are all from left to right, and if the murderer stood behind the victim to commit the murder, he would follow the normal posture...”
Lu Chuan stood up, picked up the pen holder on the table, waved it in the air, and tried to make a beating motion. (End of this chapter)
