Chen Yan still understood Li Yun's ability.

He handles cases carefully and has rich experience. He has spent half his life in the third detective team, and has experienced dozens of cases if not hundreds.

Although there are very few major cases, there are indeed a lot of trivial cases, cases of stealing chickens and dogs, and cases of missing people looking for people.

It can be said that every head of the grassroots detective team who has climbed up from the grassroots first-line detectives is an expert in handling these small cases.

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

In these aspects, Chen Yan agrees with them. After all, this is an accumulated thing, a kind of experience formed by solving cases for many years.

Take this disappearance case as an example, in fact, Li Yun has almost exhausted all the clues that can be investigated now.

The route where Chen Ziqiang disappeared that day was only a short distance away, and the surveillance cameras were searched, but he couldn't find anything.

What does this mean?

This shows that Chen Ziqiang's disappearance is probably not his own will.

But after careful planning.

Coincidentally, there are so many surveillance cameras that cannot be hidden.

It is only possible if the heart plans.

So, if Chen Ziqiang just skipped class, or left the campus by himself, why should he be so cautious?

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

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

something wrong?

What can be wrong!

Almost the whole school was searched but nothing was found.

What does this mean?

Chen Yan nodded solemnly: "If Chen Ziqiang simply skipped class, there shouldn't be a trace left behind."

"It's impossible for a student to study the surveillance cameras in the school so thoroughly. Besides, the 100-meter distance where Chen Ziqiang disappeared is a surveillance cage."

"No matter from which direction Chen Ziqiang leaves the 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, but after three days of searching, they did not find any trace of Chen Ziqiang.

"Captain Chen, what do you mean?" "Carry out a carpet search!"

Chen Yan stood at the door of the laboratory building, pointing to the nearby monitoring cage: "Send on-site survey personnel to conduct a blanket search of the nearby area."

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

Murder scene?

Li Yun was slightly taken aback, and his expression was a little surprised, but he didn't object to Chen Yan's judgment.

Chen Ziqiang disappeared without a trace. If he was the only one who skipped class, it didn't make sense at all.

"Okay, I'll arrange it now!"

After that, Li Yun contacted the school.

Using the laboratory building maintenance as an excuse, this area was blocked.

More than 20 detectives moved in and carried out a carpet search of the area.

Chen Yan came to Chen Ziqiang's dormitory.

The dormitory for boys in Liancheng Vocational and Technical College is 8 people. There are 8 big boys living in the small house. There is no cleanliness in the house, it is dirty and messy.

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

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

"Did Chen Ziqiang tell you about leaving school recently?"

Wang Canyang shook his head: "I didn't say that, when he was in class that day, he said that his stomach was a little uncomfortable, and he had diarrhea in the morning. We all know that after the teacher gave leave, he came back by himself.

"Later, when we went back to the dormitory for lunch break at noon, I didn't see him and didn't pay attention to him, but in the afternoon, we hadn't seen Chen Ziqiang come back yet."

"Then I called him, but the phone was always off and he didn't get through."

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

"Does Chen Ziqiang skip class?

"

Wang Canyang shook his head: "We entered the vocational technical college because we did not study well at the beginning. Chen Ziqiang and I studied beauty and hairdressing."

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

"Whether we can learn it or not is our own business, so when we first started school last year, everyone still skipped classes and went out to play, and use the Internet cafes for nights, but this year we didn't go out."

"Furthermore, we don't say whether we can skip class or not. The teacher doesn't care about us. He can go out whenever he wants. There is no need for Ziqiang to run out behind our backs."

"I think something must have happened to him!"

problem occurs?

"Has he any enemies?"

Wang Canyang shook his head: "We are just a poor student, so we don't 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, it's definitely out of the question."

Chen Yan was tall, so he could see everything on Chen Ziqiang's bed without tiptoeing.

The bed was a bit messy, not folded up, and the quilt was also a bit dirty, it could be seen that it hadn't 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 a lot of girls in your vocational technical college. How can you not have a girlfriend if you don't have a strong relationship with your classmates?"

Wang Canyang shook his head: "You are all old calendars. Our school was indeed the same as what you said before."

"The teachers in the school don't care about it. The former students just played like crazy. Both men and women have sex."

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

When Wang Canyang said it, he seemed to yearn for the old school atmosphere: "It's not like that now."

"Most students are busy learning a craft, and after graduating early, they can find a job and make money."

"The female classmates in our school don't like us at all."

"No matter how handsome we are, no matter how good street dancers are, no matter how cool we are, in the end we'll just be haircutters."

"Girls nowadays are very realistic. They only look for rich men when they look for boyfriends."

"A family like ours with no money, who is learning crafts here, how can there be a girl who would like it?"

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

Only regret, no lie.

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

Just a pillow, a quilt, and two nails on the wall at the head of the bed and the end of the bed, and clothes are hung on it.

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.

The people in the upper bunk nailed nails on the wall, while the people in the lower bunk tied the ropes directly to the two bedposts.

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

Each person has a small square space, where clothes cannot be put down, but some personal items 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 lost, so Chen Yan stepped forward, put on his gloves, and pressed lightly.

Click.

Under Wang Canyang's shocked gaze, the lock snapped.

Chen Yan smiled slightly and weighed the lock he just took off: "This kind of small lock looks strong, but it doesn't resist twisting, so it can be fixed with a little force.

Regardless of Wang Canyang's still shocked and puzzled eyes, Chen Yan looked at the small cabinet that had been opened.

The lockers have very little space to hold anything, but because they can be locked, everyone's valuables in the dorms are kept in the small lockers.

Chen Ziqiang is no exception.

Chen Yan glanced around, but there were actually no valuables, a poor student, how could he have anything valuable.

In one book, there are 320 yuan and a game console.

This was somewhat beyond Chen Yan's expectations. Although this handheld is not new, it was not cheap to buy it back then.

"Does Chen Ziqiang like to finish the game?"

It seems that Wang Canyang has not recovered from the shock that Chen Yan twisted the lock with one hand just now, and his eyes are still staring at the lock that Chen Yan put aside.

"Xiao Wang."

"what?"

Chen Yan patted Wang Canyang's shoulder to wake up the young man from the shock: "Chen Ziqiang has a handheld in his cabinet, does he like to play games?"

"This thing is not cheap."

"Ah, you ask that."

Wang Canyang nodded: "I like to play. We all like to play handhelds in our dormitory, but they are too expensive to afford."

"Ziqiang's is a second-hand product bought last month. It belongs to a rich second generation in our school. They have been playing for several years. The five hundred yuan is disposed of to Ziqiang."

"This guy, after eating instant noodles for a month, he saved the money to buy a handheld."

Chen Yan nodded and put down the phone.

In the cabinet, apart from a book with 320 yuan in it and the handheld, there is only one diary left.

Taking out the diary, Chen Yan opened it and looked casually.

"Xiao Wang, does Chen Ziqiang have the habit of keeping a diary?"

write diary.

Most people don't have this habit. Of the many people Chen Yan knows, there are only three or five who often keep diaries.

Among the cases handled, there was only one person who kept a diary.

However, most of the things recorded in the diary are the very real thoughts of the reporter, and even some secrets that will not be mentioned to outsiders.

For handling cases, the diaries of the parties can often provide some very important evidence.

Wang Canyang nodded: "Ziqiang and I were classmates in junior high school, and he started writing a diary in the third year of junior high school."

"But I don't write it often, I just record something occasionally, but I don't know what it is written."

Chen Yan nodded and opened the diary.

The first page is dated August 19, a year ago.

"Today is my first day entering Liancheng Vocational and Technical College, and it is also the beginning of my new life."

"I'm very happy that Wang Canyang and I have been allocated a dormitory. In the future, the two of us must study hard and become leaders in Liancheng's hairdressing industry!"

"Come on! Chen Ziqiang, you can do it!"

This diary was obviously recorded by Chen Ziqiang since he entered school last year.

After that, Chen Ziqiang kept a diary about every week, all of which were trivial matters.

"The technical school is really good, no one cares about it, but the monthly money is a bit small."

"Haha, go to the Internet cafe for a night out today!"

"The weather is fine today, I like some money, go out to go clubbing!"

"Disgusting, my goddess is on the king's **** grass, isn't it just that she has two stinky money, and when I have money, I will do the same thing."

"I skipped class today, the teacher didn't care about us, and the Internet cafe stayed all night."

"But my dad had an accident on the construction site, his leg was broken by a steel bar, and my sister got appendicitis. My living expenses this month will be reduced by a hundred yuan."

"Wang Canyang's father had a car accident, and he will be the only man in his family from now on"

"We're .going to change"

There are not many contents in the diary, but through this diary, Chen Yan seems to have experienced the changes in Chen Ziqiang's mentality over the past year.

I had great ambitions when I was just in school last year. I wanted to learn how to do it, and I wanted to start all over again.

However, the study and life in the technical school is unregulated, free and undisciplined, skipping classes and clubbing has become a daily compulsory course for Chen Ziqiang.

Then today in April, Chen Ziqiang’s father was broken by a steel bar at the construction site and was unable to earn money. Wang Canyang’s father also died in a car accident in those two days

The family misfortune made the two finally recognize the reality.

From that day on, the frequency of Chen Ziqiang's diary writing became once every two weeks.

There are very few things recorded.

"I learned ion perm during this time, but the tuition is too expensive, and my family doesn't have that much money."

"I made tinfoil ironing by myself today. The teacher praised me. I can go to Emmy for an internship tomorrow. Haha, I'm going to make money!"

"Today is the 34th day of my internship at Emmy Barbering. I finally did a highlight for a client by myself, and the boss gave me 50 bucks!"

“This is the first time in my life I’ve made money!”

"Feifei looks so good-looking. I don't know if she has a boyfriend."

On June 12 this year, a girl named Feifei appeared in Chen Ziqiang's diary.

Since then, Chen Ziqiang's diary writing frequency has increased significantly, and he will write a diary entry every day or two.

"Feifei seems to be smiling at me today, does she like me too?"

"We talked for the first time today. I invited her to drink Michelle Ice City. I deliberately chose a couple's set meal. I don't know if she found it?"

For the next month, Chen Ziqiang's diary was all about that Feifei girl.

Including what clothes she was wearing and what the two of them said, Chen Ziqiang would write it down.

Until July 9, that is, two months ago, in a diary written by Chen Ziqiang, there was secret joy between the lines.

"Feifei finally agreed to go to the movies with me!"

"Haha, she must like me too, what should I do? Should I prepare a gift for her?"

"What should I prepare? I still have 180 yuan in my pocket. It costs 80 yuan to watch a movie, and 100 yuan"

Diary for the next day.

"Feifei is a good girl. She bought drinks and popcorn when watching movies. She said that we are all students and we don't have much money. We make AA. Feifei is so kind."

"Haha, today I held Feifei's hand hahaha!"

"Why should I help her? I will definitely be able to help her!"

On August 6, one month before his disappearance, Chen Ziqiang wrote his last diary entry.

help her

Chen Yan closed the diary. Obviously, something happened to the girl named Feifei.

"Xiao Wang, does Chen Ziqiang have a girlfriend?"

"girlfriend?"

"No, no, the family conditions in our dormitory are not good. It costs money to make a girlfriend. That girl will make friends with us."

Wang Canyang's smile was a bit bitter, UU Reading , but it was very realistic: "Ziqiang definitely doesn't have a girlfriend, if he has a girlfriend, I'll be the first to know."

no girlfriend

Who is Feifei in Chen Ziqiang's diary?

"By the way, I found a girl named Feifei in Chen Ziqiang's diary. Chen Ziqiang mentioned it several times. Do you know this person?"

Fifi?

Wang Canyang shook his head suspiciously: "There are two girls in our class with Fei in their name, one is Sun Xiaofei and the other is Zhao Feiyan."

"But they all have boyfriends, and they are not very familiar with Ziqiang, and they...have no intersection in the class."

Sun Xiaofei, Zhao Feiyan.

Chen Yan wrote down the names of the two people, and then asked, "Amy Barber, do you know this place?"
