Chapter 231 The Empty Cage

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

When they heard that the monkey was lost, they laughed. When they heard that a monkey was worth 15 yuan, they cried out.

like a monkey.

However, although the case value is high, it is still the configuration of the theft case, and it is still the police from the district bureau who came over.

There were 4 people in total, including Cao Keyang, the trace inspector invited from the Municipal Bureau.

Cao Keyang ran over on his own initiative.

A few days ago, Cao Keyang regretted not being involved in the case of Jianyuan Company because he was working on other cases outside.

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

The main case-handling forces of the Qinghe City Bureau were all sent down 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 inspection and forensic medicine, and most of the time is borrowed from the city bureau.

Anyway, the technicians of the Municipal Bureau also had to go to the countryside, so they could be used by anyone, and it was more convenient for the District Bureau to use them.And save money.

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

The word "meeting" is more eye-catching.

Cao Keyang's idea is quite simple.The Jianyuan company case that Jiang Yuan worked on a few days ago started with a theft case, and two people died in one breath, the son of the chairman of Jianyuan company and his boyfriend.

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

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

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

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

It can be inferred as a matter of course that Qinghe College's death is not surprising.

Cao Keyang's eyes looked a little too expectant, making Jiang Yuan laugh and shake his head.

It's just losing 4 monkeys, which has nothing to do with dead people.

A valuable monkey is still a monkey.

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

"I understand, everything speaks with evidence." Cao Keyang said.

This is of course correct.

Although Jiang Yuan looked at Cao Keyang's expression, it was not quite right, but he still said normally: "In short, let's watch the scene first."

Cao Keyang agreed repeatedly, and then entered the medical building with other police officers.

Jiang Yuan borrowed his white coat and followed him in.

The monkeys in Qinghe College are all kept in one room, and the iron cages are now empty. Judging from the condition of the locks, they should have been cut directly with hydraulic pliers.

Cao Keyang snapped two photos. In this case, it usually turns out that an outsider committed the crime.Generally, insiders will not use a hydraulic clamp to cheat, but it is easy to be seen.

Of course, this is the general case.

The monkey house was fairly clean. Cao Keyang looked around and found a camera, so he asked outside the door: "Is there any video?"

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

"When did it break?"

"It has been broken for a year or two. It has been reported, but it has not been repaired." The young teacher replied.

The monkey house is only a small space, and the camera is shining on it, so it is somewhat uncomfortable, and the enthusiasm for maintenance is not high, which is probably understandable.

Jiang Yuan looked down at the ground again.

Some tables and chairs have been displaced, and there are some traces of being rubbed around on the ground, which is quite messy.

Because it is an indoor environment, the footprint left on the ground is not formed.

There are a few and a half feet, probably stepped on the food that landed on the ground, leaving a little pattern imprint, but there is very little information that can be given.

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

When a trace inspector speaks to a colleague like this, it is equivalent to a man saying to a woman, "Wait a minute, I will take a medicine".

No need to be ashamed, because you are used to it.

However, it is not something to be proud of.

However, it was just another ordinary day.

Doorway.

The police officers are also actively taking notes.

The person who was asked the longest was the teacher in charge of the monkey house, and he was also the reporter.

His attitude was very cooperative, and he answered every question. When the transcript was finished, he asked, "When will the monkey be found?"

"It's hard to say." The criminal police were also in a dilemma, how to guarantee the solution to the case.

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

"Hey, aren't you a teacher?"

"I'm a Ph.D. student at Agricultural University, and I'm still working." The monkey house teacher murmured, "It's been three years."

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

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

The criminal policeman wrote down a few notes in his notebook and said, "You work at Qinghe College, get a Ph.D. from Agricultural University, and then use the public monkey to write your graduation thesis?"

Teacher Houshe thought for a while and said, "It's almost like this."

"It's still you intellectuals who will do this." The criminal police clicked twice, opened the record again, and said: "Then you have offended anyone in terms of your Ph.D...."

"No."

"In other respects, have you offended anyone?"

The monkey house teacher said annoyedly: "No! I'm a scientific researcher, where can I offend people?"

The criminal police emphasized: "Under normal circumstances, people outside will not carry hydraulic pliers and come to steal your monkey. Think about it carefully, have you ever had any conflicts with people recently, have you met strange people, strange people?" Do you say something strange?"

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

The criminal policeman looked at Mr. Monkey House seriously, and said: "We will definitely investigate the monkey line. But you have to ask you to find out about the line on your side, right? Say you know it, and leave us alone. How to investigate!"

The tone here is a little more serious, and the monkey house teacher couldn't hold back anymore, so he could only lower his head to think, thought for a while, and said: "You must tell me what's the matter. Recently, there are a few calls to buy monkeys." , the price is quite high. But this monkey of mine has its own mission, so I definitely can’t sell it to them..."

The criminal police frantically took notes there.

Jiang Yuan looked around the scene, focused on taking pictures of the footprints on the ground, and found a little fiber trace in a corner of the table, carefully took it out with the evidence bag, and quietly exited the scene.

The fiber may be left by the students or teachers of the school, or it may be left by the thief. According to Jiang Yuan's naked eyes, the most relevant possibility to the case is that the thief used a bag similar to a sack to hold the monkey, and the bag was hung on the table. horn, leaving a little fiber.

If this was a murder case, these fibrous materials would have been traced as a thread.

But since it was a theft case, it would be good if it could be used as evidence in the end.If you search directly along the line, the degree of trouble is slightly higher, and it must be considered on the premise that other clues have no results.

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

The scene of a theft case is the same as the scene of a murder case. If you want to scan it in detail, you still have to spend several hours there.Moreover, back pain and leg cramps cost three to five catties of supplies.

Today's case is not Jiang Yuan's case, and he doesn't even have the right to sweep the scene when he gets to the bottom of it.

Jiang Yuan was not interested in sweeping the scene either.

There is a limit to manpower, if you encounter a case, you must do it. If you are exhausted, you will offend others.

Even if Cao Keyang has a very good attitude, he may not be happy to be taught by Jiang Yuan.

The monitoring of Qinghe College is widely distributed, and a special monitoring room is arranged.

Zeng Zhuohu and a few students also curiously followed Jiang Yuan's ass and mixed in together.

The management of Qinghe College itself is just like that. When there are too many people coming, they just ignore it and just give them a machine to show them.

The criminal policeman in charge didn't sit down, and called a staff member to come over, looking for the surveillance video one by one.

At this time, Qinghe College's many surveillance cameras showed their advantages.Because there are too many surveillance videos and too few people watch the videos, the people who watch them are exhausted.

The criminal policeman is not a professional graphic detective either, and it is difficult to find the key position, and it is even more difficult to follow the key position to find the next key position.

In several surveillance videos, the figure of the thief can be found. It seems that there are two people, 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 monitoring finally followed, followed and lost.

The first few students became bored watching it, and one of the girls came to Jiang Yuan's side and said softly, "Is this how you usually watch the surveillance?"

"It's about the same. It's boring to watch the surveillance." Jiang Yuan recalled the work content of the picture detectives, and he also felt deeply.

Don't look at the picture investigation is now a prominent science in the criminal department, often named as big data, etc., but this thing can only be called big eyes and so on in terms of operation...

As far as the monitoring mode of Qinghe College is concerned, the monitoring room is well repaired, but half of the monitoring is real-time, and only news photos are taken. It is beautiful when publicizing, and the storage monitoring time is also short. There is also a loop recording mechanism. Imperfect situation...

Still the same sentence, if one or two people die at Qinghe College, these monitoring are a treasure.

If you just throw monkeys, these surveillances will be blind.

The female student next to him naturally didn't understand Jiang Yuan's emotion, so she moved closer and said in a low voice: "Actually, if there are more equipment, we can also help to see..."

"Actually, it's not necessary." Jiang Yuan reversed his thinking at this moment, coughed twice, and said, "Look at the courtyard wall directly. If there is no exit video, you can only go out from the courtyard wall."

"Climbing over the wall is not easy. The four monkeys look quite heavy." The criminal policeman in charge said.

"One weighs about 10 catties." Zeng Zhuohu explained to him.

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

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

If this is over the wall, the suitcase will be a trouble.

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

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

"Principal Heng." Zeng Zhuohu also greeted.

Heng Wenxuan, the principal of Qinghe College, nodded with a smile, and then greeted the police, saying: "Thank you for your hard work. I heard you were discussing the case just now, so I couldn't help but want to say something. Well, the school's courtyard wall, there are Holes have been dug out in several places, but it is actually possible to get in and out."

"Turn it out from the surveillance to take a look." The criminal policeman in charge immediately said.

The staff in the monitoring room said in embarrassment: "The monitoring over there is broken after being installed, and it has not been installed again recently."

"Hmm..." The detective frowned.

"There are surveillance cameras in the small restaurant opposite the cave." The principal smiled and said, "It's just facing the entrance of the cave."

　Due to the lack of medicines, I experienced a complete fever process. My personal experience is from being afraid of cold, to afraid of heat, and then to sweating.I felt sober the whole time, but now I seem to be drowsy.Overall, it’s okay. After the burning, the teeth didn’t hurt so much, only a dull pain, and then I felt like a cold-like headache for two days. I’m in good condition today, and the swelling has subsided. try to go to the hospital...
