The reason for doing this is because even if Lu Chuan and others go down into the well and scoop out water one by one, it will have a certain impact on the body's position, but they need to be careful not to damage the bones.
Use a detection instrument to detect it first and record the entire skeleton. It may be more accurate if you analyze it later.
The other thing is to buy some high-quality waterproof clothing.
In this case, even if you go inside, wearing waterproof clothing when handling the bones can isolate the corpse water outside.
Although the water looks clear, there may be some unknown bacteria in it, including the corpses. Therefore, Lu Chuan will definitely spare no effort if safety protection can be taken.
The underwater detection equipment can be dispatched relatively quickly and can be delivered within an hour or two.
Protective clothing is more convenient. There is stock in the warehouse. Lu Yao personally drove several top-quality protective clothing to Lu Chuan.
It was already noon when everything was ready.
With these devices, the psychological pressure of criminal police officers handling cases is actually much less.
The people who operate the equipment are all professionals. The underwater survey equipment is similar to a small submarine, which is about the size of a mobile phone. After placing a counterweight underneath, it is dropped directly into the reservoir with a rope.
Because there is no disturbance in the water, the water is still very clear.
After the instrument enters, the propeller slightly stirs the instrument and slowly circulates around the body from top to bottom to record the video of the body.
Judging from the results of the video, the preservation condition of the entire corpse is relatively intact. Most of the bones are in their original positions and have not suffered any particularly significant external impacts.
Generally speaking, the decomposition time of a corpse soaked in water is about one to two years.
Of course, this means that under normal circumstances, if it is thrown into water when the weather is relatively hot, it will rot very quickly, probably in three or two months, and it will completely rot.
Judging from the situation of this reservoir, the fender covering it is exposed to the wild, which is a very suitable environment for the rapid decomposition of corpses.
On the contrary, if the entire space is sealed, the body will not necessarily rot in the water, but may instead form a waxy body.
Preserved like a mummy, it is called tanned corpse.
This kind of corpse situation is very rare, because the preservation of such a corpse requires very high external conditions.
When burying corpses in ancient times, some people would even deliberately create such conditions in order to prevent the corpse from decaying after burial.
For example, the surrounding rammed earth is rammed deep underground to form a relatively airtight space. Rich people even install a circle of quicksand or even mercury around the grave of the corpse to isolate the corpse from the outside natural environment, thus forming a A relatively vacuum sealed environment.
“Stop here!”
Instead of the instrument starting from the heel and moving downwards to record the entire entity, when it reached the thigh, Lu Chuan stopped the operators in sequence. .
Because there is a missing dislocation here.
A situation occurs where the thigh bone is misaligned upward and inserted into the chest cavity.
After taking careful notes, Lu Chuan continued to ask the staff operating the equipment to surround the entity and record the video.
But the instrument was unable to record the entire body, because the entire body from the collarbone down was buried in the mud.
“Okay, pull up the instrument and start searching for water.”
Wang Zhaokai was the first to enter the water. Although Wang Zhaokai is now the squadron leader, he is actually the most senior in the criminal police brigade.
Chen Jiang and Sun Biao from the Second and Third Squadrons were originally in his squadron. Later, after he slowly grew up and was able to work alone, he went out to take over the duties of captain of the second and third squadrons.
In other words, Wang Zhaokai can be regarded as the old leader of these two. If this happens at this time, Wang Zhaokai must be the first one.
We can't really let the director go down first.
Fortunately, the protective clothing obtained by Lu Chuan are very protective and can protect the whole person after getting into the water.
“I don’t know how deep the mud below is. When we go down like this, we all step on ladders and soft ladders to scoop water. Don’t enter the mud easily.”
Lu Chuan had just tested it with a long stick and found that the mud inside was at least one meter above.
So if people go down and stand directly in the mud, it will be very difficult to get clear water.
Fortunately, the outer extension of the reservoir is made of cement, which is relatively strong, so Lu Chuan can have a place to draw on when the situation of letting people hang up a ladder to scoop water goes on.
“Be careful not to scoop out too much water each time, and try not to stir up the mud underneath.”
The main reason why Lu Chuan wanted to take this approach was to get the ribs out. The reason is that they don't want to stir up the mud on the seabed and pollute the bones again.
It’s just that in this case, everyone can’t hold on for long, because the focusing point on the ladder is not particularly good. After scooping more than a dozen buckets of water, the back will be sore, so we can only change people to come down. .
And you have to be very careful during the whole process, otherwise, if you scoop up the mud underneath, all your efforts will be wasted.
The homework lasted for four or five hours in the afternoon of the first day. When it got dark, Lu Chuan asked for it to end, because even if there were lights, everyone was very tired. In order to prevent accidents from happening Don't rush the investigation, we'll do it again tomorrow morning.
Before the large troops evacuated, Lu Chuan arranged for the police from the police station to be on duty here to protect the scene.
Of course there is no objection from the Beitou Town Police Station. The director of the police station, Zhang Biao, personally took care of him here.
This is not to say that the criminal police brigade and others leave these side jobs to the police station, but because the police station has no way to participate in more important work.
For example, just when we went to bite the corpses, the police from the police station did not go there. All the people from the criminal police brigade were doing it.
So now the policemen from Beitou Town Police Station are on duty here, and no one has any complaints or opinions at all.
Not to mention that this was a matter arranged by the deputy director of the High-tech Zone Public Security Bureau on Jingtou. They would also do it even if other people from the criminal police brigade arranged it.
After all, this afternoon they all watched with their own eyes as the criminal police brigade went to retrieve the corpses.
However, Lu Chuan and others did not rest after returning, but held a brief coordination meeting.
“There are no problems with the two reporting personnel. Detailed inquiries have been made.”
“There have been no missing persons in the village in the past two years. There is a missing man who was on October 10. The case was reported by family members who disappeared out of town years ago. "
"There are currently no valuable clues about the identity of the body."
After several people reported the situation one after another, Lu Chuan nodded. . (End of chapter)
