National Forensic Doctor

Cai Banxun worked in Changyang City and was divorced, but he had a son who was awarded to his wife. Therefore, as long as he got his son's DNA and compared it with his own, the identity of the deceased could be determined.

Of course, judging from the rigor of the criminal police, it cannot be said that the deceased is not Cai Banxun even if the comparison is not successful. Therefore, the police also entered Cai Banxun's room and took his toothbrush and razor back for comparison.

Fortunately, several DNA samples were matched, which means the identity of the deceased was confirmed to be Cai Banxun.

In this way, all the manpower previously sent can be sent back.

The hundreds of criminal policemen sent by Lang Heng were sent to determine the source of the corpse. Now that the photo and ID number of the corpse have been released, it would be a pure waste of police force to let them continue to follow the previous clues.

Shen Yaowei was also recruited back.

There is hope in continuing to trace the swollen leather shoe, but it is nothing more than hope. The current result is more relaxing.

All the police officers who were transferred back were immediately thrown into the pile of evidence.

Nearly 120 police officers, coupled with about 30 young people, a total of 150 people, vowed to dig up this pile of evidence to the bottom.

This is a fish pond with an area of ​​15 acres. The deepest mud is 2 meters, and the average depth is more than one meter. If all the mud is dug out, the cubic meter will be 15,000 cubic meters.

Ordinary medium and large excavators such as the 200 type operate continuously. It can dig 300 cubic meters per hour, but when used to dig silt, the work efficiency is not even half. Therefore, to dig out 10,000 cubic meters of mud, more than 100 hours of machine time are allocated to 4 excavators, and each excavator needs to work for an average of 25 hours.

In fact, each excavator takes more than 30 hours, because although many people do not regard people as human beings, the excavators are indeed people.

Similarly, Shen Yaowei also did a lot of work in order to process the 15,000 cubic meters of mud.

First, he identified the site where the silt had accumulated. In addition to having a large enough area and not being complained by nearby villagers, it also needs to have convenient access to water and easy flushing of mud.

Secondly, the site must be convenient for entering and unloading vehicles, which means that transportation is convenient. At the same time, it must have a certain degree of sealing, because although the silt accumulated on the site is silt that no one wants, the silt stored in it is all physical evidence. The detectives not only have to prevent people from stealing things from here, but also make sure that no one throws things in there.

After all, the deceased died in the village's fish pond, so the villagers were not at fault at all?

If the murderer or the murderer's protector lives in the village and does something for fun at night, or even finds a few brats and throws something in, the entire chain of evidence will be challenged.

Of course, Shen Yaowei's main job is to wash away the mud. Together with the people from the criminal police detachment, he flushed the mud with water at full capacity, and then piled the washed evidence in a temporary room to avoid exposure to the sun and at the same time to protect the evidence.

In this process, Shen Yaowei and others, or in other words, the entire task force, are looking forward to some evidence that can clearly prove the identity of the deceased, such as a wallet.

If not, some rare items that obviously do not belong to the village, such as items that locals will not buy, at least will not throw away casually, or some accessories that should not appear in fish ponds, can be used as links to the deceased. things to consider.

But in fact, the case did not reach this stage at all.

Only when Jiang Yuan made no progress in forensic anthropology, and Lang Heng's team found nothing during their visits, was it possible for everyone to focus on these tens of thousands of objects.

Once you get to this step, it is absolutely impossible to just touch and touch the objects. You must first take out the objects, attach small yellow or white labels and scales, take photos and videos, and then put them into evidence. Bag, cut or wipe a part, and then send it to the laboratory for various examinations.
