Chapter 914: Major suspect

Cai Tingxun himself worked in Changyang City and was already divorced, but he had a son who was assigned to his ex-wife. Therefore, as long as he got his son's DNA and compared it with his own, he could determine the identity of the deceased.

Of course, for the rigor of the criminal police, if it doesn't match, it doesn't mean that the deceased is not Cai Tingxun. Therefore, the police also entered Cai Tingxun's room, took his toothbrush and razor back for comparison.

Very lucky, several DNA samples matched, which determined that the identity of the deceased was indeed Cai Tingxun.

In this way, all the manpower sent out before could be withdrawn.

The more than 100 criminal police officers sent by Detachment Leader Lang were to determine the source of the corpse. Now that the photo and ID number of the corpse were out, letting them continue to trace along the previous clues was purely a waste of police force.

Shen Yaowei was also recalled.

That pair of soaked leather shoes could continue to be traced, and there was hope, but it was just hope after all. The current result was more reassuring.

And all the police officers recalled were invested in the evidence pile for the first time.

A total of 150 people, including about 120 police officers and about 30 young people, vowed to turn this evidence pile upside down.

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 earthwork volume of digging out all this silt is square meters.

And ordinary medium and large excavators such as the 200 type, work continuously. Each hour can dig 300 square meters of soil, but used to dig silt, it doesn't even have half of the work efficiency. Therefore, to dig out the square meters of silt, it takes more than 100 hours of machine time. Distributed to 4 excavators, each machine also has to work for an average of 25 hours.

In fact, the time spent by each excavator exceeded 30 hours, because although many people really didn't treat people as people, those who drove the excavators were indeed people.

Similarly, in order to process this square meters of silt, Shen Yaowei also did a lot of work.

First, he confirmed the site for piling silt. In addition to the area being large enough and not being complained about by nearby villagers, it also had to be convenient for water supply and drainage, and easy to wash the evidence.

Secondly, the site had to be convenient for vehicles to enter and unload, which meant convenient transportation. At the same time, it had to have a certain degree of closure, because the silt piled up in the site was all physical evidence. The criminal police not only had to prevent people from stealing things from here, but also ensure that no one threw things into it.

After all, the deceased died in the fish pond in the village. Did the villagers have no fault at all?

If the murderer or the murderer's accomplice lived in the village, and secretly did something at night, or even found a few little brats to throw things in, the entire chain of evidence would be challenged.

Of course, Shen Yaowei's main work was still washing the silt. He and the people from the Criminal Police Detachment used full power to wash the silt with water, and then piled the evidence washed out in a temporary room one by one, avoiding exposure to the sun, which was also a kind of storage for the evidence.

And in this process, Shen Yaowei and others, or the entire task force, were looking forward to some evidence that could clearly prove the deceased's identity, such as a wallet.

If not... some rare objects that obviously did not belong to the village, such as objects that locals would not buy, at least would not be discarded at will, or some ornaments that should not appear in the fish pond, could all be considered as the deceased's related objects.

But in fact, the case did not enter this step at all.

Only when Jiang Yuan had no progress in forensic anthropology, and Detachment Leader Lang's team had no results in visiting, would everyone possibly invest energy in these tens of thousands of objects.

And once entering this step, it was absolutely impossible to just wipe and touch. It was necessary to first take out the objects, match them with yellow or white small labels and scale, take photos and videos, and then put them into evidence bags, cut or wipe a part, and then send them to the laboratory for various inspections. If the results were checked, they would be classified. If no results were checked, they would be processed again.

And if there were certain results, it would be like what Shen Yaowei did before. After getting a leather shoe suspected of being the deceased's, he would take one or two partners and go straight to the manufacturer and the like to do further investigation and visiting.

Without Jiang Yuan-level confirmation, there might be dozens of such objects. If the case was particularly major, it would be normal to deploy two or three teams for this.

Adding all these together, it meant that Detachment Leader Lang might save one or two months of time, and the saved expenses were immeasurable.

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

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

The only thing that needed to be determined was the content of the intersection, and who the object of the intersection was.

Detachment Leader Lang checked the clues handed over by all parties while making phone calls, maintaining communication with several detachment leaders.

The case had progressed to this point, and experienced police officers already knew how to do things, and didn't need him to order on the spot at all.

"Prepare a copy of these materials and take them with me." Detachment Leader Lang ordered when he went out, waited a little, and then took his subordinates to the corner building to meet Jiang Yuan.

If it were Detachment Leader Lang's previous experience, he would definitely not go to the forensic doctor or technician now. Now is the exclusive moment for iron feet.

However, the case had progressed to today's degree, and Detachment Leader Lang had finally absorbed some experience.

For example, forensic doctors can really read the deceased's ID number!

With such experience, Detachment Leader Lang couldn't go back even if he wanted to.

Even if the information in his hand didn't match the forensic doctor, he wanted to communicate with Jiang Yuan.

The top floor filled with sunlight.

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

Detachment Leader Lang was stunned for a moment, then stepped forward and smiled: "Jiang Yuan is resting? Director Liu, Huang Zhengwei."

"Ruixiang is still doing skull restoration, so I have nothing to do." Jiang Yuan said and looked at Detachment Leader Lang, asking: "Does the case have any repetition?"

"No, it's still being checked. Currently, it's still relatively smooth." Detachment Leader Lang paused, looked at Huang Qiangmin and Liu Jinghui who were stretching their short necks, and said: "We contacted the deceased's ex-wife and sister. When mentioning Pushui Town, they all mentioned a debt dispute. There was a person named Xu De, who was a fruit farmer ten years ago. He owed a sum of money from the deceased and promised that after the orchard was picked, the debt would be offset by the harvested fruit."

Detachment Leader Lang let people put the printed photos on the tea table, and added: "The market fluctuation that year was relatively large. After the orchard was picked, Cai Tingxun gave a lower price, which did not meet Xu De's ideas. Later, Xu De should have sold the fruit secretly, and the debt owed to Cai Tingxun was never repaid."

Jiang Yuan and others understood immediately and asked: "Is Cai Tingxun here to collect debts? Or what?"

"It is very likely. Cai Tingxun has not been doing well in the past two years. Xu De later stopped planting fruit trees and pushed a tricycle to the city to sell fruit, but earned well. Xu De returned to Pushui Town this year and opened a fruit shop... Currently, we believe that Xu De is a major suspect!" ===== CHAPTER 915 =====
