Chapter 231 Her Feet

Qinghe College faces the street on three sides and the water on one side.

Therefore, students opened multiple doors on three sides. The big ones are about 1.56 meters high and can be passed by bending over. The medium and large ones have to squat to get out. There are also smaller ones, which can only be delivered by air.

Looking at the traces of the red wall being dug, each hole seems to be growing.

It can be imagined that if every student touches it hard when drilling a hole, it is not a dream to expand the hole to the size of a normal door.

Qinghe College will rectify the behavior of opening holes in high walls every once in a while. The holes found will be simply filled up and the surroundings will be reinforced to prevent students from getting into danger when they open holes again after a while.

The principal's secretary sent the surveillance video of the small restaurant opposite the hole to the criminal police.

When it was turned on, the camera was directly facing the hole, which could clearly capture the faces of people entering and leaving.

"Do students know about this camera?" Jiang Yuan had just graduated from school not long ago, and he could feel the deterrent power of the video.

"Those who want to know will find out." The principal smiled proudly: "In your words, the function of this camera is mainly for investigation, not for evidence."

If it is used for evidence, it can only be used once, but if it is used for investigation, it can be used countless times.

When students sneak out of the door, they usually don't hide from the camera. They can't hide even if they want to. Therefore, as long as the existence of this matter can be confirmed here, there are plenty of cameras in the school for evidence.

Jiang Yuan looked up and down at the principal. The square-faced man looked very righteous. Unexpectedly... it turned out that the left nostril was smaller than the right nostril, which made him look a little bit evil...

"Is it useful?" Comrade Principal asked with concern, and watched the criminal police's operation, as if he wanted to learn from him.

His movements at this time were similar to those of the students under Zeng Zhuohu.

But this time, the criminal police's operation was easy for him to understand. Principal Heng Wenxuan also had an expression of learning.

In fact, what is there to learn? The criminal police here use the most basic functions.

Jiang Yuan just looked at Zeng Zhuohu's students and felt a little sympathy for them.

The principal jumped like this, and he probably had a lot of daily thoughts.

The criminal police used cameras one by one to search, and when they found the thief, they had already found 5 holes.

Jiang Yuan was a little tired of watching, and thought: It's better to open two more doors.

In the video, we can clearly see the two thieves bending down and crawling out one after another, and then handing out the suitcase.

The students passing by also helped.

But when the camera was fixed, we could see that the two thieves not only wore masks and sunglasses, but also covered their lower faces with sun protection clothes, with almost no real skin on their faces.

The criminal police watching the surveillance were angry and amused: "What do students think nowadays? No one called the police when they were dressed like this?"

Jiang Yuan felt that he was wrong, but looking at the faces of the two thieves, he felt that what he said made sense.

"By the way, if the monkey was in the suitcase, wouldn't it scream?" Jiang Yuan asked Zeng Zhuohu.

"It should scream." Zeng Zhuohu shook his head.

Jiang Yuan nodded, guessing that some medicine might have been used, but he didn't say it.

"Let's go and take fingerprints." Jiang Yuan then clicked on the top of the cave in the video.

The girl who was carrying the luggage had to hold the wall with her hands when she came out of the cave because she had to carry the suitcase, and she didn't wear gloves.

In such a hot day, covering your face can be called sun protection, but wearing gloves is too uncomfortable.

However, the two people probably wore gloves when stealing the monkeys, but they took them off after they came out. They probably didn't expect to be noticed more than ten minutes away from the animal protection building.

There are many thieves who are exposed in this way.

Outsiders may think that if I committed a crime, I must wrap myself tightly and would rather not take it off at the door.

In fact, this is difficult to do, because outsiders only think about it, but have never practiced it - this shows the professionalism of professional criminals. When they do any case, they usually practice it.

For the two thieves who stole the monkeys, the reason why they did not always wear gloves is probably not because they could not think of it, but because they could not do it.

For example, dragging a suitcase, wearing gloves, and walking under the scorching sun for more than ten minutes, you may feel tired, your hands may slip, and you may not be able to drag the suitcase.

At this time, should you rest for a while with gloves on the side of the road, or take off the gloves, wipe off the sweat and continue walking?

Or, when they are walking on the road, they may need to make a phone call or use a mobile phone, which would be inconvenient to wear gloves.

In addition, is it necessary to take off the gloves to operate the monkey packing process? There may also be such a need for feeding medicine to monkeys or giving injections.

In short, criminal activities are both mental and physical activities. In the actual process, it is inevitable to encounter some unexpected problems and difficulties.

If you can perfectly overcome this process without doing exercises, it requires considerable professionalism.

If a newcomer can achieve this level, it is actually recommended to be an agent.

As a criminal scientist, I never believe in perfect crimes.

Even ordinary policemen don't believe in it. Everyone believes that increasing input will lead to more output.

From the perspective of ordinary police officers, people like Jiang Yuan are also considered inputs.

…

A large group of people came to the cave entrance in a mighty manner, and Jiang Yuan personally took the fingerprint.

To be honest, this fingerprint is not easy to extract.

First of all, the location is not easy to determine, and secondly, there are multiple overlapping fingerprints, which requires some professional skills to handle.

Jiang Yuan's method is to first determine the location of the brick, then take a photo of the entire brick, number it, and then directly remove it and send it to the laboratory for extraction.

This is also because the case is not from the Ningtai County Bureau, and it is thrown to the Qinghe City Bureau's laboratory, so that a copy of the evidence can be kept later.

After doing all this, Jiang Yuan leisurely returned to Zeng Zhuohu's office and continued to help him watch the video.

The students admired him very much, while working harder to learn imaging technology, they served tea and water for Jiang Yuan, and served him.

Later, several more little girls rushed into the office.

Zeng Zhuohu turned a blind eye, and he had no right to say anything, so he just watched from the side and tried not to lose control.

To the girls, the tall and big Jiang Yuan might only get 80 points for his appearance, but today he looks different with the halo.

"Forensic doctor Jiang, you took the bricks to extract fingerprints from them, right?"

The girls watched Jiang Yuan typing some incomprehensible command lines on the computer, and someone asked about today's news events.

Jiang Yuan said "yeah" and said, "That's about it."

The girl who asked the question had a slender figure, flat chest, a pointed chin, and a bit of a celebrity face. She was wearing good makeup and looked very beautiful. She asked in a soft voice, "What happens after the fingerprints are extracted? Do you know who it is?"

"If it is extracted, it will be compared."

"What does comparison mean?"

"It means comparing with the fingerprints in the fingerprint database."

"Fingerprint database? If it's not in the fingerprint database, there is no way to compare it, right?"

"Yes." Jiang Yuan answered and turned to look at the girl who asked the question.

Several people asked similar questions today, and this is the first time they asked such detailed questions.

At this time, a girl from the student union said ostentatiously: "If it's a student of this school, he can't run away."

"Why?" The girl with the internet celebrity face looked over curiously.

The lady from the student union curled her lips, glanced at her, and said: "Don't you have to punch in every morning when you run? Isn't your fingerprint stored in the fingerprint system used for punching in?"

The internet celebrity face girl was stunned, and her face changed.

This performance was a bit beyond the normal level. Jiang Yuan couldn't help but lower his head and look at the girl's feet.

After taking a look, Jiang Yuan silently took out his mobile phone and sent a message to the criminal police who led the team this time.

"Well, I'll go first." I don't know if she saw Jiang Yuan's operation, the girl turned around and walked out the door.

Jiang Yuan didn't even move his butt.

At this time, Zeng Zhuohu also saw something wrong, and hurriedly said: "Don't you want to stop it?"

"No, it can't run far." Jiang Yuan made a phone call directly after he finished speaking.

It's too dangerous for a single police officer to arrest people, and the team won't allow it.
