Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

While the excavation was being carried out here, Wang Zhaokai was conducting surveys and visits to the village, while Chen Jiang was mainly responsible for investigating the construction team members.

"National Highway 121 is mainly expanded this time."

The government has already introduced the person in charge of the national highway renovation project to explain why the national highway needs to be renovated this time.

Mainly because National Highway 121 is one of the important passages out of Haizhou City from the urban area.

"There are only two roads exiting Haizhou City to the northwest, and National Highway 121 has the largest traffic volume."

The person in charge is Wang Hu, who rushed to the scene after being notified of the incident.

"Originally, National Highway 121 was only a two-way single lane. After this expansion, it can be changed to a two-way four-lane."

"When was it last built?"

Chen Jiang recorded the basic information and then asked questions.

"Ten years ago, National Highway 121 existed. It used to be a gravel road, but it was later rebuilt. The cement road was dilapidated 10 years ago due to the weathering of the cement. It was renovated and turned into an asphalt road."

Judging from this clue, the deceased should have been buried under the foundation when National Highway 10 was renovated and turned into an asphalt road 121 years ago.

"Does the construction party have records from that year?"

Wang Hu nodded affirmatively: "This must exist. The last time the 121 National Highway was renovated, formal bidding was also used. Which construction party undertook this section. I have to go back and check the information."

On the other side, Sun Biao was investigating the construction team.

The person in charge of the construction, named Lin Fan, was crying and mourning as the bones were dug out...

This project will definitely not go on.

If there is no significant progress in the case within a short period of time, it is estimated that this section of the crime scene will remain sealed.

In this case, for them, the construction period cannot be guaranteed.

Of course, this Lin Fan is not a good person.

During this period of construction, they occupied a cemetery in a village in Donggou Township in order to build a road.

At that time, it was clear that a detour could be done, but Lin Fan took the initiative and moved other people's cemeteries, which caused a lot of civil disputes.

There have been several conflicts here because of this matter.

The local police station has also been coordinating this matter.

But it is not illegal to say that it is illegal. The cemetery bought by the villagers originally occupied part of the cultivated land.

Lin Fan took out Huazi and wanted to order it for Sun Biao.

The conflicts that occurred these few times were all resolved by Sun Biao, so Lin Fan and Sun Biao were considered acquaintances.

Blocking the cigarette Lin Fan handed him back, Sun Biao frowned: "You kid, don't do this to me."

"Did you find anything wrong during the construction work these past two days?"

Lin Fan's head shook like a rattle.

"No, Captain Sun, you are just kidding me. We don't know where the bones are buried. We are just responsible for the renovation. I was not the one who did the last job, and that was all 10 years ago. ”

"Construction in the blocked area will be suspended for a while. You can work elsewhere first. If you find anything, call me at any time."

"I understand, I will do as you say."

"Don't take this seriously. The scene must not be damaged. This is a murder case. If the scene is damaged, you will be legally responsible."

Sun Biao was afraid that the other party would be generous, so he explained it specifically.

"And please calm down with the villagers. Don't have conflicts and beat people up every time. What will you do?"

"Although there is something wrong with the place where his grave is buried, it is his ancestral grave after all. You pushed his ancestral grave. Otherwise, it would be weird if I didn't fight for you. Give him some money to fix this matter. Isn’t it over?”

"Yes, yes, I understand. I will do exactly what you want."

After Sun Biao roughly understood the situation, he didn't ask any more questions. The bones were buried 10 years ago and have nothing to do with the current construction team. At 4: in the morning, all the skeletons were finally cleared out.

The work on site has come to an end.

"Take everything back and do a DNA test first to see if you can confirm your identity."

"Yes!"

After returning to the criminal police brigade, Lu Chuan had no time to rest.

In the corpse pit where the bones were found, a shovel was also found.

It is very likely that they were the digging tools left behind by the murderer.

Lu Chuan is now inspecting the shovel.

The wooden handle hasn't rotted yet, but it also has a lot of clay.

What Lu Chuan hopes most now is the murderer. When he was digging, he left fingerprints on the wooden handle.

Although 10 years had passed and the fingerprints might have been exhausted long ago, Lu Chuan still carefully cleaned the wooden handle of the shovel in the hope of being safe.

Wang Hao is doing DNA identification on the skeleton, and the results will probably be available tonight.

In other respects, there are currently no more clues.

It is still not possible to confirm whether the missing person Wang Zhaokai found in the village is the skeleton.

DNA comparison and identification are required for final confirmation.

It is difficult to extract fingerprints on wooden supports.

Especially for wood that has a rough surface and has not been painted, the possibility of extracting fingerprints from the surface is generally not high.

Because the wooden structure carrier has the characteristics of absorbing oil.

Human fingerprints are left on general wooden structures, such as the wooden handle of a shovel, and the oil will be absorbed by the wood itself within a certain period of time.

Fingerprints are a mixture of oil and sweat secreted by the skin on the finger surface. If it is absorbed, it will naturally disappear.

Lu Chuan didn't want to find fingerprints left 10 years ago on the wood itself. This was theoretically impossible.

What he focused on was the clay that fell off the glass from the wooden handle.

If the murderer had indeed used the shovel and was not wearing gloves, he would have left fingerprints on it.

Fingerprints will not disappear in a short period of time. If it is covered with a layer of soil, it is very likely that the mud will imprint the remaining fingerprints of the murderer.

Although it may not be particularly clear, just a little bit can bring a lot of clues to solve the case.

The hard work paid off, and Lu Chuan finally succeeded in peeling off a small piece of sticky clay on the end of the wooden handle close to the shovel.

Inside, there is a rubbing mark one-third the size.

Although it is a bit rough, it is a clue after all!

"it is good!"

Lu Chuan originally just had the attitude of giving it a try, but he didn't expect that it would actually work.

This is also related to the nature of the clay on the roadbed.

If the ground is soft sand, there probably won't be any way to extract anything.

Fortunately, the clay under the roadbed of National 121 has relatively large moisture content.

After careful extraction, Lu Chuan began to conduct identification and analysis.

Although it was only one-third the size of a normal fingerprint, it was enough for Lu Chuan to conduct identification and analysis.

Now let’s see if there is a target fingerprint in the fingerprint database. (End of chapter)
