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 facing 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 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.
With the principal dancing 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 really 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 helped me.
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 kind of medicine might have been used, but did not say anything.
"Go over and get your fingerprints." Jiang Yuan clicked on the top of the cave in the video picture.
The girl who was carrying the luggage had to carry the suitcase, so when she came out of the cave, she supported the wall with her hands, 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 only took off their gloves 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 were 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 have never practiced it - here you can see the professionalism of professional criminals. When they do any cases, 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 thought of it, but more likely because they couldn't do it.
For example, if you drag a suitcase and wear gloves for more than ten minutes under the scorching sun, you may be 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.
In addition, do you need to take off your gloves during the monkey packing process? This may also be required for operations such as feeding the monkeys medicine or giving injections.
All in all, criminal activities are both mental and physical activities. In the actual process, you will inevitably 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 investigator, I never believe in perfect crimes.
Even ordinary police officers don’t actually 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 of multiple people, so processing requires a bit of professional skills.
Jiang Yuan's method is to first determine the location of the brick, then take photos of the entire brick, number it, then directly remove it and send it to the laboratory for extraction.
This is also because the case did not belong to the Ningtai County Bureau and was left to the laboratory of the Qinghe City Bureau so that a piece of evidence could 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 techniques while pouring water for tea at the far end of the river, riding in front of and behind the horse.
Later, several more little girls poured into the office.
Zeng Zhuohu turned a blind eye and 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 internet celebrity face. She was wearing good makeup and looked very pretty. She asked in a sweet voice: "What happens after the fingerprints are extracted? You guys will
Do you know who it is?"
"If you 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 eloquently: "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 fingerprint is stored in the fingerprint system used for clocking in."
The internet-famous girl was stunned for a moment, and her expression couldn't help but change.
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.
