Chapter 582 Li Yun Reports

It is naturally impossible to disappear out of thin air. This is the real world, not a magical world.

However, Chen Yan naturally believed in Li Yun's abilities.

Moreover, all the inspection contents of Li Yun were specified by Chen Yan.

There is only so much area in the entire experimental building area that is not recorded by surveillance cameras.

The place where Chen Yan arranged for Li Yun to inspect could be said to be extremely detailed.

All bathrooms in the entire building were inspected, including urinals, urinals, floor drains under the sinks, and all drains.

But nothing has been found so far.

Chen Yan even asked Li Yun to conduct fluorescence detection of blood traces on all these hidden parts.

This is the simplest method of field work to determine whether blood stains are present.

Use fluorescent lights to shine on the wall to see if there are blood stains.

Of course, this fluorescence method can not only determine whether blood stains exist, but also make certain judgments if they are contaminated by other contaminants.

However, if there is no response through this method, further testing will be a waste of time.

There is also a septic tank.

Li Yun's people conducted a composition test on the septic tank of the toilet sewage in the laboratory building.

If Chen Ziqiang was really killed, and then the body was processed and discharged through some method, then the contents of the septic tank would not be able to escape after all.

Chen Yan came into contact with a case in his previous life.

The murderer was the victim's husband. Because of the long-term conflicts in his life, the husband killed his wife late at night and disposed of the body.

The murderer's psychological quality is very strong. He did not reveal any flaws when faced with questioning, and he was still able to talk eloquently even when facing reporters.

Investigators found no trace of the crime in his home.

Similar to Chen Ziqiang's disappearance, the woman seemed to disappear out of thin air.

No surveillance records, no witnesses, nothing.

But the entire community is only that big. If the woman is not seen leaving in the video at the door, then the woman is still in the community.

The septic tank is the last hidden place in the community.

Finally, human DNA tissue was discovered during the examination of septic tank sewage.

Finally, the suspect was identified and the case was solved.

With this experience, Chen Yan would certainly not let Li Yun miss the septic tank.

But, unfortunately, nothing was found.

Standing on the roadside next to the experimental building, Chen Yan stared around.

With such a palm-sized area, where can one go?

Is it possible to go to heaven and earth?

"By the way, have you checked the water tank in the laboratory building?"

Li Yun shook his head: "This experimental building is only 6 stories high. It is a multi-story building. There is no water tank on the roof and no elevator."

"The first floor of the experimental building is a lecture theater, the second floor is a laboratory for the pastry major, and the third floor is a laboratory for the chef major."

"Some traces of blood and some hair were detected under the sink in the bathroom on the third floor. However, tests have been done and they are all animal hair and animal blood."

"I have checked with teachers and students at the school. The chef's professional laboratory sometimes handles some raw meat, and students will have blood stains on their hands. They usually wash them in the sink in the bathroom."

"Others, no abnormalities were found."

It is impossible to go to the sky, and there are no discoveries in the laboratory building, and the septic tank underground...

Chen Yan looked at the manhole covers on the road in a daze.

There are three manhole covers on this 100-meter-long road that is not monitored.

Um?

Three?

"Captain Li, are these manhole covers all septic tank manhole covers?"

"No, there is only one manhole cover for domestic sewage, and the other two are for heating and one for electricity."

Li Yun pointed to the manhole cover in the distance that was within the surveillance range of the camera: "That manhole cover over there is the water supply manhole cover."

"We have checked all these manhole covers."

"The space inside is very small, and it is impossible for anyone to leave from here. Moreover, we also checked for traces below and found no suspicious clues."

Li Yun sighed: "Captain Chen, we only have three feet left to dig in this area. We really have searched all the places we can find."

Regarding disappearance cases, Li Yun has also taken over many cases, and there are always more than a dozen cases.

When Li Yun first joined the police, surveillance was not yet developed. There were no surveillance cameras in many places, and there were many cases of missing children.

But even at that time, many things were traceable.

At least a few witnesses can be found.

In recent years, there have actually been fewer and fewer disappearances, especially compared to more than 20 years ago.

Coupled with the increasing popularity of surveillance systems, it has become much easier to find a missing person.

Although whether this person can be found in the end is another matter, there are many clues every time.

Monitoring, tickets, taxi records, etc.

But the disappearance of Chen Ziqiang made Li Yun feel a little emo.

There are really no clues.

How could a place disappear so quickly?

Chen Yan stood on the side of the road and looked around at the surrounding woods. In the distance, students who had finished class came out of the teaching building in twos and threes.

The disappearance of one student did not have much impact on other students. Everyone was attending class normally, with smiles on their young faces.

Chen Yan shook his head. It was impossible to disappear into thin air.

There must be some details that Chen Yan and others overlooked.

But it doesn't matter, just because no clues were found at the scene of the disappearance, it doesn't mean that other clues can't guide Chen Yan to solve the case.

The information provided by Wang Canyang and Huang Jingya, as well as the things recorded in Chen Ziqiang's diary, are very valuable clues.

While listening to Li Yun's report, Chen Yan had already sent Zhang Chaoyang to the Amy Barber Shop on Longjiang Road to look for the Feifei in Chen Ziqiang's diary.

It can be seen from Chen Ziqiang's diary that Chen Ziqiang likes Tian Feifei.

Huang Jingya also said that the relationship between the two is unusual.

The most important thing is the last diary entry written by Chen Ziqiang on August 6,

"What should I do...I should help her...I will definitely be able to help her!"

This she should refer to Tian Feifei.

What happened to Tian Feifei on August 6, and Chen Ziqiang felt that he must help her?

And just after August 6, according to Huang Jingya, Chen Ziqiang did not go to Amy Barber Shop for a few days.

Chen Yan also checked with Wang Canyang in those days. They went to practice during the day and returned to school at night.

Therefore, it is impossible for Chen Ziqiang to go back to school during the day.

So what did he do?

Why did Chen Ziqiang never write a diary after August 6?

You know, since Chen Ziqiang met Tian Feifei, he has basically written a diary every day.

But after August 6, there was no record in the diary.

Why?

Did the two of them break up?

But even if they break up, Chen Ziqiang should record it in his diary.

A month later, Chen Ziqiang mysteriously disappeared.

So is his disappearance related to Tian Feifei?

What role did Tian Feifei play in Chen Ziqiang's disappearance?

Judging from the clues obtained so far, the disappearances of Tian Feifei and Chen Ziqiang should be related to a certain extent.

Therefore, Chen Yan sent Zhang Chaoyang to investigate Tian Feifei. Maybe Chen Ziqiang's disappearance could find a breakthrough in Tian Feifei.

Buzz.

Just as he was thinking about it, Chen Yan's phone vibrated.
