Chen Yan still understands Li Yun's ability.

He handles cases carefully and has rich experience. He has been working in the Third Detective Team for half his life and has experienced hundreds to dozens of cases.

Although there are very few major cases, there are indeed a lot of trivial cases, cases of stealing and missing persons, and cases of missing persons.

It can be said that every leader of the grassroots detective team who has risen from the ranks of frontline detectives is an expert in handling these small cases.

Although it does not mean that every case they handle can be solved, the experience they have accumulated is indeed rich.

In these respects, Chen Yan agreed with them that this was something accumulated and an experience formed by solving cases over many years.

Taking this disappearance case as an example, Li Yun has actually investigated almost all the clues that can be investigated now.

The route that Chen Ziqiang went missing that day was just a short distance away, and the surveillance cameras were all checked, but nothing was found.

What does this mean?

This shows that Chen Ziqiang’s disappearance is probably not his own wish.

But it is planned from the heart.

It's a coincidence that there are so many surveillance cameras.

It is only possible with careful planning.

So, if Chen Ziqiang was simply skipping classes, or if he left the campus on his own, would he be so cautious?

Looking at Chen Yan's serious expression, Li Yun seemed to have other guesses in his mind.

"Captain Chen... do you think there is something wrong with Chen Ziqiang's disappearance?"

has a problem?

What could be the problem!

I searched almost the entire school but found nothing.

What does this mean?

Chen Yan nodded solemnly: "If Chen Ziqiang simply skipped class, he shouldn't have left any traces."

"It is impossible for a student to study the surveillance cameras in the school so thoroughly. Besides, the 100 meters away from where Chen Ziqiang disappeared is a surveillance cage."

"No matter where Chen Ziqiang leaves this smoke monitoring blind spot, there are surveillance cameras around him that can spot him."

It is true that Li Yun and the others sent a lot of manpower, and after three days of searching, no trace of Chen Ziqiang was found.

"Team Chen, what do you mean?" "Carry out a blanket search!"

Chen Yan stood at the door of the experimental building and pointed to the nearby surveillance cage: "Send on-site investigators to conduct a carpet-like search of the nearby area."

"Especially in hidden corners such as bathrooms and floor drains, search them according to the standards of a murder scene!"

Murder scene?

Li Yun was slightly stunned, and his expression was a little surprised, but he did not object to Chen Yan's judgment.

Chen Ziqiang disappeared without a trace. If it was just him skipping classes, it seemed unreasonable at all.

"Okay, I'll make arrangements right now!"

Afterwards, Li Yun contacted the school.

Using the excuse of maintenance of the laboratory building, this area was cordoned off.

More than twenty detectives moved in and conducted a blanket search of the area.

Chen Yan arrived at Chen Ziqiang's dormitory.

The boys' dormitory of Liancheng Vocational and Technical College has 8 rooms. There are 8 big boys living in the small house. The house is not tidy at all, it is dirty and messy.

"Uncle Detective, the bed on the upper right side by the window is Chen Ziqiang's bed."

The person who led Chen Yan over was Wang Canyang, Chen Ziqiang's roommate in the same dormitory, and Chen Ziqiang's best friend.

"Has Chen Ziqiang told you recently that he is leaving school?"

Wang Canyang shook his head: "I didn't tell you. He said he felt a little uncomfortable in his stomach during class that day, and he had diarrhea in the morning. We all know that he came back on his own after the teacher allowed the leave.

"Later, when we went back to the dormitory for a lunch break, I didn't see him and didn't care. But in the afternoon, we hadn't seen Chen Ziqiang back yet."

"Then I called him, but the phone was always turned off and there was no connection."

"We told the teacher about this during class in the afternoon and then called the police."

"Does Chen Ziqiang usually skip classes?

"

Wang Canyang shook his head: "Those of us who entered the vocational and technical college were not good at learning at first. Chen Ziqiang and I studied beauty and hairdressing."

"Generally those who study these things are from poor families. Our tuition fees are very expensive every semester, so during class the teacher doesn't care whether you skip class or not."

"Whether we learn well or not is our own business, so when we first started school last year, everyone skipped classes and went out to play, including nights at Internet cafes and so on, but this year we didn't go out."

"Besides, there is no question whether we should skip class or not. The teacher doesn't care about us. We can go out at any time if we want. There is no need for Ziqiang to run out on our backs."

"I think something must have happened to him!"

problem occurs?

"Does he have any enemies?"

Wang Canyang shook his head: "We are just poor students, how can we have any enemies?"

"There are some gangsters in the school, but they have nothing to do with us. We all avoid them."

"Usually there are some fights between classmates, but if you want to talk about enemies, you can't talk about them."

Chen Yan is very tall and can see everything on Chen Ziqiang's bed without tiptoeing.

The bed was a little messy and not folded, and the quilt was a little dirty. It could be seen that it had not been washed for a while.

Looking at the other beds, they are all similar.

"Does Chen Ziqiang have a girlfriend?"

"How can he have a girlfriend?"

"I heard that there are many girls in your vocational and technical college. If the relationship between classmates is not strong, how can you not have a girlfriend?"

Wang Canyang shook his head: "You are an old man. Our school used to be exactly what you said."

"The teachers in the school don't care. The students in the past were just having fun. Both men and women had sex with each other."

"But we didn't catch that good time."

When Wang Canyang talked about it, he seemed to yearn for the old school atmosphere: "It's no longer like that now."

"Most students are busy learning a trade so that they can find a job and make money after graduating early."

"The female classmates in our school are not interested in us at all."

"No matter how handsome we are, no matter how good we are at hip-hop, and no matter how cool we are, in the end we will just be a guy who cuts hair and holds a big spoon."

"Girls these days are very realistic. When looking for a boyfriend, they always look for rich men."

"How can a girl like us, who have no money at home and learn a craft here, like us?"

When Wang Canyang spoke again, Chen Yan carefully analyzed the changes in his expression.

Only regret, no lies.

Chen Yan opened the quilt on Chen Ziqiang's bed and examined it carefully.

There was just a pillow, a quilt, and two nails driven into the wall at the head and foot of the bed, and clothes were hung on them.

All dormitories and shops are configured like this.

The room is small, there are many people, and there is no wardrobe. All the clothes can only be hung on the wall.

Those in the upper bunk will drive nails into the wall, while those in the lower bunk will tie ropes directly to the two bedposts.

At the door, there are two rows of iron cabinets on the left and right.

Each person has a small square space. Clothes cannot be placed, but some personal belongings can be placed.

"Which small cabinet belongs to Chen Ziqiang?"

"Well, the cabinet with the yellow lock in the middle on the right belongs to Ziqiang."

Chen Yan followed the direction of Wang Canyang's finger and looked at the small cabinet.

The key to the lock on the small cabinet must have been missing. Chen Yan stepped forward, put on his gloves, and pressed lightly.

Click.

In Wang Canyang's shocked eyes, the lock snapped.

Chen Yan smiled slightly and weighed the lock he had just taken off: "This small lock looks strong, but it is not resistant to twisting and can be fixed with a little force.

Ignoring Wang Canyang's still shocked and confused gaze, Chen Yan looked at the small cabinet that had been opened.

The cabinet has very little space and can't hold much, but because it can be locked, everyone's valuables in the dormitory are in the small cabinet.
