National Forensic Doctor

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

Therefore, the students opened multiple doors on three sides. The large one was 1.56 meters high and could be passed by bending down. The middle and large students had to squat down to get out. There were also smaller ones that could only be sent through the air. takeout.

Looking at the marks of digging on the red wall, every hole seems to be growing.

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

Every once in a while, Qinghe College will rectify the practice of digging holes in high walls. The holes found will be simply filled in, and the surrounding areas will be reinforced to prevent students from being in danger when they open holes again after a period of time. .

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

When you open it, you will see that the camera is pointed directly at the entrance of the cave, and it can clearly capture the faces of people entering and exiting.

"Do students know about this camera?" Jiang Yuancai had just graduated from school and could feel the intimidating power of the video.

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

It can only be used once for evidence, but it can be used countless times for investigation.

When students go out secretly, they usually don't hide from the cameras. Even if they want to hide, they can't. Therefore, as long as the existence of this matter can be confirmed, there are plenty of cameras in the school to use as evidence.

Jiang Yuan looked at the principal up and down. The man with the Chinese character's face looked very righteous and awe-inspiring. Unexpectedly... he turned out to be a man whose left nostril was smaller than his right nostril. He looked a bit mean...

"Is it useful?" Comrade Principal asked with concern, and watched the criminal police's operations, as if he wanted to steal his lesson.

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

But this time, the detective's operation was easy for him to understand. Principal Heng Wenxuan also looked like he had learned something.

In fact, there is nothing to learn. The criminal police here use the most basic functions.

Jiang Yuan just looked at a few of Zeng Zhuohu's students and felt a little sympathy for them for no reason.

If the principal dances like this, he probably has a lot of daily thoughts.

The criminal police used a group of cameras to search. By the time they found the thief, they had already searched five holes.

Jiang Yuan looked a little tired and thought to himself: It's better to open two more doors.

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

Students passing by also gave me a hand.

But when the camera is fixed, it can be seen that the two thieves not only wore masks and sunglasses, but the lower half of their faces were also covered by sun protection clothing, with almost no real exposed skin on their faces.

The detective watching the surveillance was angry and amused: "What do students think nowadays? No one calls the police when they are dressed like this?"

Jiang Yuan felt that what he said 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 packed in the suitcase, wouldn't it bark?" Jiang Yuan asked Zeng Zhuohu.

"She should be able to scream." Zeng Zhuohu shook his head.

Jiang Yuan nodded, guessing what medicine might have been used, but did not say it.

"Go over and get your fingerprints." Jiang Yuan clicked on the top of the cave in the video picture.

The girl who was moving the luggage had to carry the suitcase, so when she came out of the cave, she held her hands against the wall, and she didn't wear gloves on her hands.

On such a hot day, covering your face can still be called sun protection, but wearing gloves would be too uncomfortable.

However, the two of them probably wore them when they stole the monkey. They took off their gloves only after they came out. They probably didn't expect to be noticed ten minutes after leaving the animal protection building.

There are not many thieves exposed like this.

An outsider might think that if it was me who committed the crime, I would be wrapped up tightly and would rather not take it off until the door.

In fact, this is very difficult to do, because outsiders only think about it and never practice it - here you can see the professionalism of professional criminals. When they do any case, they usually practice it.

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

For example, if you drag a suitcase and wear gloves for more than ten minutes under the scorching sun, you may become very tired, your hands may become slippery, and you may not be able to drag the suitcase.

At this time, should I wear gloves and rest for a while on the roadside, or should I take off my gloves, wipe off the sweat and continue walking?

Or, when they are walking on the road, they may need to make calls or use mobile phones, and wearing gloves may also be inconvenient.

Also, do I need to take off my gloves during the monkey packing process? Operations such as feeding medicine to monkeys or giving injections may also require this.

All in all, 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 any exercises, it will require considerable professionalism.

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

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

Even ordinary police officers don’t believe it. Everyone believes that increasing investment will produce more output.

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

…

A large group of people arrived at the entrance of the cave, and Jiang Yuan personally took their fingerprints.

Speaking of which, this fingerprint is not very easy to extract.

Firstly, it is difficult to determine the location. Secondly, there are overlapping fingerprints from multiple people, which requires some professional skills to handle.

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

This is also because the case does not belong to the Ningtai County Bureau and is left to the Qinghe City Bureau's laboratory so that a piece of evidence can be stored later.

After doing this, Jiang Yuan returned to Zeng Zhuohu's office leisurely and continued to help him refresh videos.

The students were so impressed that they worked harder to learn imaging technology while pouring water for tea on the far side of the river.

Later, several more little girls poured into the office.

Zeng Zhuohu turned a blind eye. He didn't stand up to speak. He just watched from the side and tried not to lose control.

For girls, Jiang Yuan, who is tall and big, may only score 80 points in appearance, but today with the halo bonus, it looks different.

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

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

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

The girl who asked the question was slender and flat-chested, with a pointed chin and a rudimentary face of an Internet celebrity. She was wearing good makeup and looked very beautiful. She asked in a sweet voice: "What happens after the fingerprints are extracted? You guys will Do you know who it is?"

"If you can extract it, compare it."

"What does comparison mean?"

"Just compare it with the fingerprints in the fingerprint database."

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

"Yes." Jiang Yuan answered and at the same time 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 conspicuously: "If you are a student of our school, you can't run away."

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

The student union lady curled her lips, glanced at her, and said, "Don't you have to clock in every morning for exercise? Your fingerprints are stored in the fingerprint system used to clock in."

The internet-famous girl was stunned for a moment, and her expression changed involuntarily.

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 looking at it twice, Jiang Yuan silently took out his mobile phone and sent a message to the criminal policeman who led the team this time.

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

Jiang Yuan didn't even move his butt.

At this time, Zeng Zhuohu also saw that something was wrong and hurriedly said: "Why don't you stop me?"

"No, you can't run far." After Jiang Yuan said that, he called directly.

It's too dangerous for a single police officer to arrest someone, and the team won't let him.
