The rise of nanometers

Just when Huang Xiuyuan was planning to continue heading north.

Ma Jun, who had just been transferred from the Rizhao Branch of Shandong Province, hurried to the hotel.

"Mr. Huang, there is an unexpected situation." The panting Ma Jun hurriedly kept the story short and reported the general situation of the matter to Huang Xiuyuan.

Huang Weichang asked hurriedly: "Have you called the police?"

"Reported."

Huang Xiuyuan frowned, and after thinking for a moment, he ordered: "Go over and have a look."

Soon, in the parking lot next to the hotel, minibuses and convoys drove toward the southwest of Taikang County and along the Guohe River.

After entering the suburbs and driving for more than three kilometers, there was a road next to the river embankment and a large cotton field on the other side of the road.

On the river embankment, several garbage trucks were parked, and on the water of the river, a floating raft and excavator had stopped.

A cordon was set up at the scene, warning lights were flashing, and the local police were already busy.

Just after Huang Xiuyuan got off the car, Taikang County Police Director Xie Yingqi rushed to the scene sweating profusely. He saw Huang Xiuyuan and his party. The two sides introduced their identities. Facing the big boss of Suiren Company, Xie Yingqi also gave a brief introduction. Surprised.

"Thank you, can I take a look?"

Xie Yingqi thought for a while and agreed, but asked Huang Xiuyuan and others to cooperate and not approach the evidence casually.

Huang Xiuyuan took Huang Weichang and Zhang Lei and followed Xie Yingqi through the cordon and into the sealed simple tent.

Since Huang Xiuyuan and others were wearing gas helmets, there was no serious odor, but the on-site inspection personnel all looked embarrassed.

A rusty gasoline barrel with a hole punctured by an excavator bucket and signs of being cut by workers.

Since Blue Age has contracted Zhoukou's sanitation and water services, this year's drought has caused the water level of the Guohe River to drop a lot. Blue Age cooperated with the local area and arranged a river dredging plan.

This section of the river was cleared today. The excavator dug out a gasoline barrel in the mud at the bottom of the river. When the workers saw sand and gravel flowing out of the punctured location, they planned to pour out the sand and gravel and take away the gasoline barrel.

As soon as they cut it open, they found the bloated body.

Huang Xiuyuan took a look and saw that the body had been severely decomposed, leaving only a layer of skin wrapping the bones and rotten flesh inside. Perhaps because the welds of the gasoline barrels were small, the body had not been eaten by fish.

The on-site surveyor reported to Xie Yingqihui: "Judging from the environment and degree of decomposition of the body, the time of death should be more than three months."

"Did you find any identification marks?"

"No, not even the clothes were found."

Xie Yingqi then asked: "Can DNA still be extracted?"

"That's no problem."

Huang Xiuyuan looked at the corpse on the plastic sheet and suddenly said: "Can I see the teeth of the corpse?"

"Uh?" The prospector didn't know how to answer for a moment.

Xie Yingqi advised: "Mr. Huang, leave the professional matters to us!"

"I just have something to verify. Do you remember the milk poisoning incident more than four months ago? The four suspects and the car disappeared right here in Zhoukou."

As soon as Huang Xiuyuan reminded him, Xie Yingqi immediately reacted. This incident was a big deal at the time, and he had also participated in related investigations.

It's just that the Santana was driven exclusively on national highways with sparse surveillance. Although a small area was locked in after collecting surveillance data, no trace of the vehicle or the suspect was found, and no specific clues were found.

Xie Yingqi led a team to conduct an investigation in the surrounding area and found only one suspected car accident scene. Only the information found at the scene also had no clues.

"Mr. Huang, do you also know about forensic identification?"

"I understand a little bit." Huang Xiuyuan made an understanding accordion gesture.

Xie Yingqi could only give the scout a look: "Then let Mr. Huang take a look."

With the help of the explorers, Huang Xiuyuan saw the condition of the teeth in the mouth of the corpse, and his knowledge about autopsy and related biology was immediately recalled in his mind.

"Age 33 to 35 years old. I have a long-term smoking habit. I have had dental implant surgery on the upper second premolar. The brand of dental implant used is Orthotax, and the implantation time is about 4 years..."

"This person is 178 centimeters tall and weighs 58 to 60 kilograms. There are signs of fracture and healing on the right humerus. He should have been injured 14 to 15 years ago. This person is an acquired left-hander..."

Xie Yingqi has a very good memory and clearly remembers the characteristics of the four suspects. Judging from Huang Xiuyuan's inspection results, it matches the characteristics of one of the suspects.

Huang Xiuyuan reconstructed the person's face in his mind based on the skull of the corpse, and he quickly drew a restoration diagram.

"This is Zhang Dalei." Xie Yingqi exclaimed.

Huang Xiuyuan took off his gloves, turned around and ordered Zhang Lei: "Let the dredging team take action. The bodies of the other three suspects are most likely in the nearby river."

"Understood." Zhang Lei hurriedly ran out.

Xie Yingqi hurriedly ordered his subordinates to collect the suspect's detailed files.

Half an hour later, another gasoline barrel was unearthed from the river mud. It was also stained with rust and welding marks.

After opening the gasoline barrel, it turned out to be a rotting corpse inside.

Two hours later, the remaining two gasoline barrels and the body were dug out. At this time, the top leader of the Zhoukou police also rushed to the scene with his team.

The preliminary autopsy conclusions of a group of forensic doctors were similar to Huang Xiuyuan's.

However, Huang Xiuyuan did not stay. The two parties exchanged a few words and then ordered the Zhoukou branch to cooperate with the investigation. He, Huang Weichang and others continued north to Shandong Province.

Not long after Huang Xiuyuan left.

Xie Yingqi quickly reconstructed the scene of the case based on the time of death of the body, the place where it was thrown into the river, and the missing Santana car.

"Yingqi, you mean that this group of people, after being murdered while absconding, moved to Guohe River to destroy their bodies and eliminate traces." The leader was also thinking.

Xie Yingqi nodded: "Yes, the car accident scene I reported last time is most likely the scene of the first crime."

The idea suddenly became clear. Zhoukou police compiled relevant information and sent blood and corpse extracts from the car accident scene for DNA testing and comparison.

After the matter was reported to the joint task force, personnel were immediately organized to conduct a blanket search around Taikang County, and at the same time, surveillance data along the way were retrieved for further analysis.

Since the crime scene and the body dumping site are inconsistent, and the weight of the four gasoline barrels, it must have been transported by means of transportation. It can hold a Santana and four gasoline barrels, so the vehicle must be a large truck or the like.

The suspected target was quickly identified, and three large trucks passing by at that time came into the sight of the task force.

But soon they got into trouble again, because one of the large trucks was most likely a kit truck.

Since more than four months have passed since the case, judging from the professional methods of these guys, the task force is pessimistic about the next investigation work.

Huang Xiuyuan didn't take this matter seriously. After all, mice can't see the sun.

Finally, on September 11, the convoy arrived in Linqing, Shandong Province. Li Weibin, the manager of the local branch, had already arranged accommodation at the headquarters.

The day after tomorrow is the opening ceremony of the Dongying-Linqing line.
