Chapter 581： Report by Li Yun

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 ability.

Moreover, all of Li Yun's inspections were specified by Chen Yan.

This is the size of the area of ​​the entire laboratory building that is not recorded by the surveillance cameras.

It can be said that Chen Yan arranged for Li Yun to conduct inspections, which can be said to be very detailed.

All the toilets in the entire building were checked, including the urinals, toilets, floor drains under the washstand, and all places where the water was drained.

But so far nothing has been found.

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

This is one of the easiest field work methods to determine whether there is blood.

Use fluorescent light to illuminate the wall to see if there is blood.

Of course, this fluorescence method can not only judge whether there is blood stains, but also can make certain judgments if there are other dirt contaminations.

However, if this method does not respond, further testing is a waste of time.

There is also a septic tank.

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

If Chen Ziqiang was really killed, and then the body was disposed of and discharged by some method, then the things in the septic tank would not be able to escape after all.

Chen Yan was involved in a case in his previous life.

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

The murderer's psychological quality is very strong, he didn't show any flaws when facing the questioning, and he was still able to talk freely even when facing the reporters.

The investigators did not find any traces 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 so 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, after testing the septic tank sewage, human DNA tissue was found.

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

With this experience, Chen Yan certainly wouldn't let Li Yun miss the septic tank.

But, unfortunately, nothing was found.

Standing on the side of the road next to the laboratory building, Chen Yan stared around.

Where can people go in such a place the size of a palm?

Can it still 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, and it is a multi-storey building. There is no water tank on the roof, and there is no elevator."

"The first floor of the laboratory building is a lecture hall, the second floor is a pastry professional laboratory, and the third floor is a chef professional laboratory."

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

"I have checked with the teachers and students of the school. Some raw meat is sometimes processed in the chef's professional laboratory. The students' hands will have blood on their hands, and they are usually washed in the sink in the bathroom."

"Others, no abnormalities were found."

It is impossible in the sky, and there is nothing found in the laboratory building, and the underground septic tank

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

There are three manhole covers along the unmonitored 100-meter-long road.

Um?

three?

"Captain Li, are these covers for septic tanks?"

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

Li Yun pointed to the manhole cover in the distance that is within the monitoring range of the camera: "The one over there is the manhole cover for water supply.

"We have checked all these manhole covers."

"inside

The space inside is very small, it is impossible for someone to leave from here, and we also conducted a trace inspection on the bottom, and found no suspicious clues. "

Li Yun sighed: "Team Chen, in this area, we are only three feet away from digging. We really searched all the places we could find."

Regarding missing cases, Li Yun has also taken over quite a few cases, and there are always more than a dozen cases.

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

But even then, many things were traceable.

At least a few witnesses can be found.

In the past few years, there have been fewer and fewer cases of disappearances, especially compared to twenty years ago.

Coupled with the increasing popularity of monitoring systems, it is much easier to find a missing person.

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

Monitoring, tickets, taxi records, etc.

But the case of Chen Ziqiang's disappearance made Li Yun a little elated.

There is really no clue.

How could it disappear in such a short time?

Chen Yan stood on the side of the road, looking around at the surrounding groves. In the distance, students who had finished their classes 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 classes normally, with smiles on their youthful faces.

Chen Yan shook his head, it is impossible to disappear out of thin air.

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

But it doesn't matter, no clues were found at the scene of the disappearance, which 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 all very valuable clues.

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

From Chen Ziqiang's diary, it can be seen that Chen Ziqiang likes Tian Feifei. UU reading

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

Most importantly, the last diary entry written by Chen Ziqiang on August 6th,

"Why should I 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 Emmy Barbershop for a few days.

In the past few days, Chen Yan also checked with Wang Canyang. They went to practice during the day and only went back to school at night.

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

So what did he do?

And why did Chen Ziqiang never write a diary after August 6?

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

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

why?

The two broke up?

But even if there was a breakup, Chen Ziqiang should record it in his diary.

A month later, Chen Ziqiang disappeared strangely.

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 disappearance 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.

hum.

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