One day passed, and although Chen Yan and others investigated many clues, they still made no progress as to the cause of Chen Ziqiang's disappearance.

Shen Yunyi lay in Chen Yan's arms, looking at Chen Yan with a somewhat sad face, thinking that his performance just now was not perfect: "Husband, what's wrong?"

"Oh, it's okay. I was thinking about a case during the day."

"Hmm? Another murder?"

"This time it's not. It's a disappearance case. A student from Liancheng Vocational and Technical College disappeared three days ago."

"The disappearance case is not easy to handle. There are so many surveillance systems now. Doesn't your investigation team have some kind of sky-eye system? If you go inside and check it out, won't you be able to find it?"

Chen Yan smiled and scratched Shen Yunyi's nose: It's not as simple as you said. If there are clues in the surveillance video, I won't have to be so upset."

"The student entered a surveillance blind spot when he disappeared, but the scope of the surveillance blind spot was very small, with only more than 100 meters of road and an experimental building."

"We checked all the surveillance videos of that school that day and found no clues about this student."

"I also personally checked the laboratory building, but still found nothing. The student seemed to have disappeared out of thin air."

"Okay, okay, hubby, have a good night's rest. Isn't it just a missing case? You have solved so many major and serious cases, and you are still stumped by such a small case. There must be some details that have not been discovered yet. , have a good sleep, my husband is the best, it will be done tomorrow!”

Xiao Yujie still has a hard time comforting people: "Well, I listen to you, go to sleep!"

Early the next morning, Chen Yan felt refreshed and went directly to the Third Detective Team.

Zhang Chaoyang arrived a little earlier than him.

"Team Chen, our guess is correct. Chen Ziqiang's 300,000 yuan was really cash obtained from some pawn companies."

I have to say that Chen Ziqiang was really cruel for Tian Feifei.

This guy used the same rhetoric, prepared the same materials, and visited twelve pawn companies in two days to apply for loans at the same time.

Except for three families who did not agree to his loan, none of the other nine families were left behind.

"This kid borrowed 300,000 yuan in cash from nine pawn companies with one card, some with more than 50,000, some with less than 10,000, some promised to repay within one month, and some promised to repay within one month. There are also those who promise to pay back within two weeks, and others like Lixingda which promise to pay back within one week.”

"But except for Li Xingda, none of these companies have approached Chen Ziqiang. Because the loan period has not expired, the possibility of them kidnapping Chen Ziqiang...is not high."

Zhang Chaoyang’s analysis is good.

Pawn companies are not kidnapping companies. Their ultimate goal is to make money. They often use a combination of carrot and stick to deal with borrowers.

First of all, make sure that the principal is recovered within the specified time, and then it will be interest.

Beating people to death with a stick is not their style. The best way to make money is to make money slowly and steadily.

Therefore, it is impossible for these people to take risks when the loan is not due.

In other words, judging from the current situation, Chen Ziqiang's disappearance seems to have nothing to do with these nine pawn companies.

"Captain Li, how is your investigation going?"

"It's still going on. The matter of Tian Feifei being expelled for fighting in a group last year has been investigated clearly. All the students involved have been found. Now we are sending people to talk to each one."

Chen Yan nodded: "Okay, you can continue to push forward. If there is any news, notify me as soon as possible. Yesterday, I asked the school to copy the monitoring points in the experimental building and the chef laboratory. I will go and take a look."

"yes!"

In the temporarily arranged office, Chen Yan was watching the monitoring of the pastry and chef laboratories.

When Chen Ziqiang disappeared four days ago, it was after 10:20 in the morning. Chen Yan looked back from this time point.

Needless to say, there were no classes in the pastry laboratory that day, and the surveillance videos were all empty.

On the other hand, the chef laboratory on the third floor was very lively. Dozens of people were clanging pots and pans inside. The scene was not just a scene, it was like a battlefield.

One moment this stove was on fire, and the next moment there was a scream from that stove.

Two people in charge

The teacher was busy putting out fires everywhere and was extremely busy.

This was the first time Chen Yan saw a chef student learning to cook, and he felt inexplicably happy.

It’s hard to imagine that the chef who cooked the delicacies he ate in Zhuyuan grew up like this.

These guys seem to be much less talented in cooking than me.

In the video, Chen Yan watched it for a while and then focused his attention on the students who were coming in and out.

Chen Ziqiang left the teaching building at 10:20, and it only took about two or three minutes to walk near the experimental building. If he was killed, it would have happened after 10:20, so he went in and out during this time, especially when leaving the classroom.

Only people have time to commit crimes.

As for the others, there was no time at all to commit the crime.

Thinking of this, Chen Yan's main force was put on all the students who came in and out of the laboratory.

However, until the experimental class ended at 1 o'clock at noon, no students left, and no students came in.

this.

Something's wrong.

Picking up the phone, Chen Yan dialed Li Yun's number: "Captain Li, check the status of all the students in the chef laboratory on the third floor of the experimental building on the day Chen Ziqiang disappeared and see if there are any students who have asked for leave."

"Yes, I'll make arrangements right away."

After deploying the task, Chen Yan continued to watch the video.

Li Yun moved very quickly, and within ten minutes the sign-in form for that day's class and the list of students asking for leave were sent to Chen Yan's mobile phone.

There were a total of 67 students in the experimental class that day, and they were a mixture of people from the two classes.

There were 69 students who were supposed to arrive, but 67 actually showed up. One of them had already asked for leave for 7 days to go back to his hometown, and another one asked for temporary leave because of a cold.

Zhou Haitao and Ma Jianning, the two students who asked for leave, the one who returned to his hometown is called Ma Jianning, but he has not returned to school yet, and the student who asked for temporary leave that day is named Zhou Haitao.

After the list was sent, Li Yun also called: "Ma Jianning's situation has been verified. This student's mother is seriously ill and he is now in his hometown."

"The situation of another student, Zhou Haitao, is a bit special. This student is currently being questioned by us."

"ask?"

Li Yun was arranging for an in-depth investigation into Tian Feifei's group fight last year. The students involved at that time were being questioned by detectives from the third team.

"You mean this Zhou Haitao participated in last year's group fight?"

"Yes, and he was the main organizer at the time. Although he was not expelled last year, he was given a major demerit by the school."

After hanging up the phone, Chen Yan thought carefully and continued to watch the video. In the morning video, no students came in or out, which meant that they had no time to commit crimes. In the afternoon video, Chen Yan focused on those who had returned to the laboratory for class.

On Zhou Haitao.

Zhou Haitao's talent seems to be pretty good, and he doesn't make a fuss like most students.
