Chapter 230: The Cage Is Empty

The performance of the Qinghe City police officers was similar to Wei Zhenguo.

When they heard that a monkey was lost, they laughed. When they heard that a monkey was worth 150,000, they screamed.

Like a monkey.

However, although the case value was high, it was still a theft case, and the police who came were still from the district bureau.

A total of 4 people, including Cao Keyang, the trace investigator invited from the municipal bureau.

Cao Keyang came here on his own initiative.

A few days ago, Cao Keyang was working on other cases outside and was not able to join the Jianyuan Company case, which he deeply regretted.

This time, as soon as the criminal police in the district called, he ran over as soon as he was called.

The main case-handling force of the Qinghe Municipal Bureau is all transferred to the districts and counties. However, the difference between the district bureau and the county bureau is that there are relatively few technical positions, including trace investigators and forensic doctors, and most of the time they are borrowed from the municipal bureau.

Anyway, the technical personnel of the municipal bureau also have to go to the countryside and districts, and they will be used by anyone, and it is more convenient to use them in the district bureau. And it saves money.

When Cao Keyang arrived at Qinghe College and saw Jiang Yuan, he immediately asked, "Will someone die?"

The word "will" is quite eye-catching.

Cao Keyang's idea is quite simple. The case of Jianyuan Company that Jiang Yuan worked on a few days ago was not a theft case. Later, two people died in one go. The dead were the son of the chairman of Jianyuan Company and his boyfriend.

If Jianyuan Company is the peak of Qinghe City's private economy, then the peak of the academic world is Qinghe College.

Although it is only a junior college, Qinghe College has a history of more than 50 years, and the principal has a high administrative level.

As a logical trace investigator, Cao Keyang subconsciously speculated that Jiang Yuan was foresighted and reasonable.

For example, the death of Jianyuan Company on the eve of its listing is a very reasonable thing.

It is natural to infer that the death of Qinghe College is not surprising.

Cao Keyang's eyes are a little too expectant, which makes Jiang Yuan laugh and shake his head.

It's just that 4 monkeys were lost, which has nothing to do with death.

A valuable monkey is still a monkey.

But in Cao Keyang's opinion, this smile is too intriguing.

"I understand, everything is based on evidence." Cao Keyang said.

This statement is naturally correct.

Although Jiang Yuan looked at Cao Keyang's expression and felt that it was a bit wrong, he still said normally: "Anyway, let's take a look at the scene first."

Cao Keyang agreed repeatedly and followed other police officers into the animal hospital building.

Jiang Yuan borrowed a white coat and followed him in.

All the monkeys in Qinghe College are kept in a room. Now the iron cage is empty. Judging from the lock, it should be cut directly with hydraulic pliers.

Cao Keyang snapped two photos. This situation usually proves that it was committed by an outsider. Insiders generally don't clamp another hydraulic pliers to fake it, but it is easy to be seen.

Of course, this is the general situation.

The monkey house was cleaned up fairly well. Cao Keyang looked around and found a camera, so he asked outside the door: "Do you still have the video?"

"It's broken." The young teacher in charge of the monkey house was a little dazed at the moment.

"When did it break?"

"It's been broken for a year or two, and it's been reported, but it's never been repaired." The young teacher answered.

The monkey house is a small space, and it's a bit uncomfortable to have a camera. It's understandable that the enthusiasm for maintenance is not high.

Jiang Yuan looked down at the ground again.

Some of the tables and chairs were moved, and there were some traces of rubbing on the ground, which looked quite messy.

Because it was an indoor environment, the footprints left on the ground were not formed.

There were a few half-foots, probably because they stepped on the food on the ground, leaving a little pattern mark, but the information they could provide was very little.

Cao Keyang looked back at Jiang Yuan, and seeing that he didn't say anything, he said to the criminal police who came with him: "You go check the surveillance, I'll scan the fingerprints here to see if there is any breakthrough."

When a trace detective talks to a colleague like this, it's like a man saying to a woman, "Wait a minute, I'll take a pill."

There's no need to be ashamed, because I'm used to it.

But it's not worth being proud of.

However, it's just another ordinary day.

At the door.

The police officers are also actively taking notes.

The teacher in charge of the monkey house was the one who was questioned the longest, and he was also the one who reported the case.

His attitude was very cooperative, and he answered every question. After the record was finished, he asked back: "When can the monkey be found?"

"That's hard to say." The criminal police were also embarrassed. How could they guarantee the case to be solved?

The teacher in the monkey house looked at him blankly and said, "This is my graduation thesis."

"Hey, aren't you a teacher?"

"I'm studying for a doctorate at the Agricultural University, and I'm working." The teacher in the monkey house murmured, "It's been 3 years."

"What's the relationship between monkeys and your graduation thesis?"

The teacher in the monkey house said, "My graduation thesis is about the breeding of rhesus monkeys..."

The criminal police made a few notes in the notebook and said, "You work at Qinghe College, study for a doctorate at the Agricultural University, and then use public monkeys to write your graduation thesis?"

The teacher in the monkey house thought for a while and said, "That's about it."

"You intellectuals are good at this." The criminal police clicked his tongue twice, reopened the transcript, and said, "Did you offend anyone in your doctoral studies..."

"No."

"What about other aspects? Did you offend anyone?"

The teacher in the monkey house said angrily, "No! I'm a scientific researcher, where can I offend anyone?"

The detective emphasized: "Under normal circumstances, people outside will not come to steal your monkeys with hydraulic pliers. Think carefully, have you had any conflicts with others recently, have you encountered any strange people or strange things? , say strange things?”

"Why do you have to chase me and ask?" The teacher from the monkey house said dissatisfied: "This is obviously just for the sake of stealing monkeys."

The detective looked at the monkey house teacher seriously and said: "Monkey, we will definitely pursue this line. But for your line, don't we have to ask you to know it? You say you know it, leave us alone. How to investigate!"

The tone here was a little more serious, and the monkey house teacher couldn't hold it in any longer. He could only lower his head and think. After thinking for a while, he said: "You must tell me what's wrong. Recently, there have been a few calls to buy monkeys." , the price offered is quite high, but I, a monkey, have my own mission, so I definitely can’t sell it to them..."

The criminal policeman was there frantically taking notes.

Jiang Yuan looked around the scene, focusing on taking photos of the footprints on the ground. He also found a trace of fiber on a corner of the table, carefully took it out in the evidence bag, and quietly left the scene.

The fiber may have been left by a student or teacher at the school, or it may have been left by a thief. Jiang Yuan judged with his naked eye that the most relevant possibility to the case was that the thief used a bag similar to a sack to hold the monkey, and the bag was hung on the table. corners, leaving a little fiber.

If this was a murder case, these fiber materials would have been used as a line to trace.

But since it was a theft, it would be good to use it as evidence in the end. If you follow the clues directly, the trouble will be slightly higher, and it will only be considered if other clues have no results.

After leaving the scene, Jiang Yuan followed Wei Zhenguo to watch the surveillance.

The scene of a burglary is the same as the scene of a murder. If you want to scan it in detail, you still have to go there for several hours. Moreover, my back aches and my legs cramp, which consumes three to five kilograms of supplies.

Today's case is not Jiang Yuan's case. Looking into other cases, he does not have the power to sweep the scene.

Jiang Yuan was not interested in sweeping the scene.

Manpower has its limits. If you encounter a case, you must do it. If you don't say it, you will be exhausted and you will offend others.

Even if Cao Keyang has an excellent attitude, he may not be happy to be instructed by Jiang Yuan.

Qinghe College's surveillance is widely distributed, and a special surveillance room is arranged.

Zeng Zhuohu and several students followed Jiang Yuan curiously and mixed in together.

The management of Qinghe College itself was just like that. When there were too many people, they simply ignored it and only gave them a machine to see.

The criminal police officer in charge did not sit down, but asked a staff member to come over and search for surveillance videos one by one.

At this time, Qinghe College's numerous surveillance systems showed their advantages. Because there are too many surveillance videos and too few people watching them, the people watching them are extremely tired.

The criminal police officer is not a professional map detective. He can hardly find the key locations. It is even more difficult to follow the key locations to find the next key locations.

The thieves can be found in several surveillance videos. They appear to be a man and a woman dragging two suitcases, but their faces cannot be seen clearly and their identities cannot be confirmed. The most difficult thing is that the surveillance finally followed him, but then lost him again.

A few students were the first to become bored. One of the girls came close to Jiang Yuan and said in a soft voice: "Do you usually watch the surveillance camera like this?"

"Absolutely. Watching surveillance is quite boring." Jiang Yuan recalled the work content of the detectives and felt deeply about it.

Even though picture detective is a prominent science in the criminal department nowadays and is often called big data, at the operational level, this thing can only be called big eyes and so on...

As for the monitoring model of Qinghe College, it seems that the monitoring room is well built. As a result, half of the monitoring is real-time. Only news photos are taken. It is beautiful for external publicity. The stored monitoring time is also short, and there is a loop recording mechanism. Imperfect situation…

Again, if one or two people die in Qinghe College, these surveillances will be valuable.

If you just lose the monkey, these surveillances will be the blindness of the detective.

The female student next to him naturally didn't understand Jiang Yuan's emotion, so she got closer and whispered: "Actually, if there are more equipment, we can also help look at it..."

"Actually, there's no need." Jiang Yuan changed his mind at this moment, coughed twice, and said, "Just look at the courtyard wall. If there is no exit video, it can only be from the courtyard wall."

"It's not easy to climb over the wall. Four monkeys look quite heavy." The detective in charge said.

"One weighs almost 10 kilograms." Zeng Zhuohu explained in front of him.

"The suitcase is a bit heavy. It's okay to push it, but it will be more tiring to climb over the wall, right?" The criminal police officer in charge pointed to the screenshot of the previous video.

The two thieves were pushing two boxes, one large and one small. They were not very light after all.

If you go over the wall, the suitcase will be a problem.

"Maybe it got out of the hole in the wall." The person who spoke this time was obviously a little older.

Someone looked over unexpectedly and immediately stood up straight and shouted: "Principal."

"Principal Heng." Zeng Zhuohu also said hello.

Heng Wenxuan, the principal of Qinghe College, nodded with a smile, and then greeted the police specifically, saying: "Thank you for your hard work. I heard you were discussing the case just now, and I couldn't help but want to say something. Well, the school's courtyard wall has There are holes dug out in several places, which are actually accessible.”

"Then call it from the surveillance camera and take a look." The criminal police officer in charge said immediately.

The staff in the monitoring room said in embarrassment: "The monitoring over there broke down after it was installed, and it has not been installed recently."

"Hmm..." The criminal police frowned.

"There is a monitoring system in the small restaurant opposite the cave." The principal smiled and said, "It is facing the cave entrance."

Due to the lack of medicine, I went through the whole fever process. My personal experience is that I was afraid of cold, afraid of heat, and then sweating. I felt sober throughout the whole process, and now I feel drowsy. Overall, it's okay. After the fever, the tooth didn't hurt so much, just a dull pain, and then I had a stuffy head with cold-like symptoms for two days. I feel good today and the swelling has subsided. I heard that the lockdown has been lifted. I will try to go to the hospital tomorrow...
