Chapter 934 Major Suspect

Chapter 934 Major Suspect

Cai Tingxun himself worked in Changyang City. He was divorced, but his son was awarded to his wife. Therefore, as long as they could get his son's DNA and compare it with his own, the identity of the deceased could be confirmed.

Of course, from the perspective of criminal police rigor, if the comparison fails, it cannot be said that the deceased is not Cai Tingxun. Therefore, the police went into Cai Tingxun's room and took out his toothbrush and razor for comparison.

Fortunately, several DNA samples matched, which confirmed that the deceased was indeed Cai Tingxun.

In this way, all the personnel previously sent out can be withdrawn.

The hundreds of criminal police officers sent out by Lang Heng were to determine the source of the corpse. Now that the photograph and ID number of the corpse have come out, it would be a sheer waste of police resources to ask them to continue investigating based on the previous clues.

Shen Yaowei was also recruited back.

There is hope if we continue to trace the swollen leather shoe, but it is just hope. The current result makes people feel more relieved.

All the police officers who were recalled were thrown into the pile of evidence at the first time.

Nearly 120 police officers and about 30 young people, a total of 150 people, are determined to dig up this pile of evidence.

This is a fish pond with an area of ​​15 mu. The deepest silt is 2 meters and the average depth is more than one meter. The volume of earth dug out from all the silt is 15000 cubic meters.

Ordinary medium and large excavators, such as the 200 type, can work non-stop and dig 300 cubic meters of soil per hour, but they are not even half as efficient when used to dig silt. Therefore, to dig out 10000 cubic meters of silt, more than 100 hours of machine time are required. If four excavators are assigned to do the work, each one will have to work for 4 hours on average.

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

Similarly, Shen Yaowei also did a lot of work to deal with the 15000 cubic meters of sludge.

First, he identified a site for the silt accumulation, which had to be large enough and not attract complaints from nearby villagers, and also had to have convenient water supply and drainage to make it easy to wash away the silt.

Secondly, the site should be convenient for vehicles to enter and unload, that is, convenient for transportation. At the same time, it should be closed to a certain extent, because although the sludge piled up in the site is unwanted, the sludge contains all the evidence. The criminal police not only have to prevent people from stealing things from here, but also ensure that no one throws things in.

After all, the deceased died in the village’s fish pond. Don’t the villagers have any fault?

What if the murderer or his protector lives in the village and does something secretly at night, or even finds a few kids to throw something in? The entire chain of evidence will be challenged.

Of course, Shen Yaowei's main job was to wash away the sludge. Together with the criminal police detachment, he used water to wash away the sludge at full capacity, and then piled the washed evidence in a temporary room to avoid exposure to the sun and to preserve the evidence.

During this process, Shen Yaowei and others, or the entire task force, were expecting some evidence that could 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 would not buy, or at least would not throw away casually, or some ornaments that should not appear in the fish pond, can all be considered as objects associated with the deceased.

But in reality, the case never got to this point.

Only if Jiang Yuan makes no progress in forensic anthropology and Lang Heng's team finds nothing during their visit, will everyone be able to focus their energy on these tens of thousands of objects.

Once it reaches this stage, it is absolutely impossible to simply touch and rub. Instead, the object must be taken out first, with a small yellow or white label and scale, photographed and filmed, and then put into an evidence bag, cut or erase a part, and then sent to the laboratory for various inspections. If the inspection results are found, it will be classified, and if the inspection results are not found, it will be processed.

And if there are certain results, we will have to do what Shen Yaowei did before, get a leather shoe that is suspected to belong to the deceased, take one or two partners, go straight to the manufacturer or something like that, and conduct further investigation and visits.

If there hadn't been Jiang Yuan's confirmation, there would have been dozens of such items. If the case was particularly serious, it would have been normal to deploy two or three teams of people.

All of this added together means that Langheng is likely to save a month or two, a saving of inestimable money.

Sitting in the office, looking at the photos sent back by his subordinates, Lang Heng's breathing became heavy.

The deceased Cai Tingxun was not only a wholesaler, but also an agricultural product wholesaler, which means that it would be easy for him to have intersections with the villagers of Pushui Town.

The only thing that needs to be determined is the content of the intersection and who the object of the intersection is.

While checking the clues handed over by various parties, Lang Heng was making phone calls and maintaining communication with several team leaders.

At this stage of the case, the experienced police officers already knew what to do and there was no need for him to come to the scene to give orders.

"Prepare a copy of these materials and follow me." Lang Heng gave the instructions as he went out, and after waiting for a while, he took his men to the corner tower to meet Jiang Yuan.

Based on Lang Heng’s previous experience, he would definitely not go to find a forensic doctor or technician now. Now is the time for the iron-footed ones.

However, as the case has progressed to this point, Lang Heng has learned some experience.

For example, forensic doctors can actually read the deceased’s ID number!

After such an experience, even if Lang Heng were asked to go back to the past, he would never be able to do so.

Even though the information in his hand seemed irrelevant to the forensic doctor, he still wanted to communicate with Jiang Yuan.

The top floor is filled with sunshine.

Opposite the floor-to-ceiling window, Jiang Yuan was facing the city scenery outside the window... leisurely playing with his mobile phone and drinking tea with Liu Jinghui and Huang Qiangmin.

Lang Heng was stunned for a moment, then walked forward and said with a smile: "Is Jiang Yuan resting? Director Liu, Political Commissar Huang."

"Rui Xiang is still doing skull reconstruction, so I'm fine." Jiang Yuan said, looking at Lang Heng and asked, "Is there any recurrence in the case?"

"No, we are still investigating. So far, it is going relatively smoothly." Lang Heng paused, looked at Huang Qiangmin and Liu Jinghui who were craning their necks beside him, and said, "We contacted the deceased's ex-wife and sister. When it comes to Pushui Town, they all mentioned a debt dispute. There was a man named Xu De, who was a fruit farmer ten years ago. He borrowed money from the deceased and promised to use the harvested fruit to offset the debt after the orchard was harvested."

Lang Heng had someone put the printed photos on the tea table and continued, "The market fluctuated greatly that year. After picking the fruits at the orchard, Cai Tingxun offered a low price that did not meet Xu De's expectations. Later, Xu De must have sold the fruits secretly and never repaid the money he owed to Cai Tingxun."

Jiang Yuan and the others understood immediately and asked, "Is Cai Tingxun here to collect a debt? Or what?"

"It's very likely. Cai Tingxun hasn't had a good time in the past two years. Xu De later stopped growing fruit trees and went to the city to sell fruit on a tricycle, which made him a good profit. Xu De returned to Pushui Town this year and opened a fruit shop... At present, we believe that Xu De is a major suspect in the crime!"
