Chapter 1193 Image Detection Case

Boss Qin, whose real name is Qin Yiming, is 42 years old and is the head of Minghao Repair Shop. Since his wife has divorced him and the child was awarded to the woman, he lives alone in the shop and manages the daily operation of the shop.

Tonight, Uncle Qin was going to wash his hands and start watching videos. Just as he lay down on the bed, he heard a violent knock on the door.

"Police!"

When he opened the door, a fierce-looking policeman in police uniform showed his ID.

Before Boss Qin could see clearly, a group of policemen squeezed in. Someone walked in and asked, "How many people live here? Is there anyone else?"

"No, I'm the only one." Boss Qin answered quickly.

"It's okay. We have a case and need to borrow it in front of your door." The instructor of the local police station came over and spoke to Boss Qin in a friendly manner, and then said, "By the way, you have a lot of cars here. Can we rent them for one night? Pay the money."

"You can use them as you like." Boss Qin answered very straightforwardly. The luxury cars in the repair shop are inevitably driven out by the mechanics to go for a ride and pick up girls, and it won't hurt to give them to the police.

The instructor of the police station naturally couldn't use them casually in front of a group of city police officers. He patted Boss Qin on the shoulder and said, "You are thoughtful, and you still have to pay. You can issue an invoice later and write Changyang City Criminal Police Detachment..."

This is work for the Criminal Police Detachment, so the expenses are naturally the Criminal Police Detachment. The instructor doesn't need Huang Qiangmin to teach him, and he still has the basic theory.

Outside the repair shop, Jiang Yuan and others have begun to measure the distance according to the position on the video.

The quality of the surveillance cameras installed in the factory and the repair shop here is very average, and they don't have night vision function at all, let alone full color level, black light level, and ordinary infrared function, so no vehicle information can be obtained at all.

In comparison, the light beam of the vehicle is more obvious, but to confirm the arrangement characteristics of the headlights in detail, there are still certain requirements for the clarity of the video. Moreover, it is best to do it when the vehicle is moving slowly. In this case, it is most appropriate when the vehicle turns in front of the repair shop.

Several trace inspectors used the cracks on the ground, roadside stones and plants and other features to measure the exact distance as accurately as possible.

Fortunately, the video was obtained, so they could always measure it several times to make corrections.

After everything that can be measured on the ground was measured clearly, a policeman drove over and began to try to analyze the scene. At this point, it was actually ordinary trace inspection work.

Ordinary trace inspections to restore the scene are mostly experimental in nature. A typical example is whether a body can fit in a suitcase. It is very simple. Find someone with a similar body size and try to get in.

It is similar to watching surveillance. Trace inspectors first find a few limited positions in the surveillance video to barely determine the position of the vehicle. Based on this, the test vehicle is parked at the position, the headlights are turned on, and then according to the width and position of the headlights, they can try to determine whether it is the same type, height or even the same brand.

Just drive a few cars to try, the responsible trace inspector soon got the idea and reported to Jiang Yuan: "Now it seems that it should be a small or medium-sized vehicle, basically excluding large trucks."

"Thank you for your hard work." Jiang Yuan responded with encouragement.

He knows vehicle trace identification, but he doesn't know the specific appearance of each car's headlights. There is no database for this thing, so he can only try one by one and let other trace inspectors test them one by one.

However, he himself can't go to rest. This is more or less a burden for his reputation. If it were more than a year ago, he would be a pure guest military forensic doctor or expert trace inspector, and he only needed to do his best.

But now, for a small case like the theft of dangerous goods, even if an expert group is established, the team leader must be Jiang Yuan. As the person in charge, Jiang Yuan can't be too irresponsible.

A group of people stayed up half a night in front of the repair shop.

One by one, the borrowed cars lined up to be tested. As for where the car was borrowed from, it was not a difficult task for the police team.

The trace inspectors in charge of the test became more and more skilled and faster.

Despite this, the expressions of several trace inspectors were still very serious.

The test had to be done at night. It would be troublesome to look at the traces of the headlights after dawn. If we waited for another day,

and then did the test, it would be a long delay.

Wang Chuanxing next to him also thought of the same problem. While yawning, he began to silently check the rental price of the photography shed and the rental requirements of the warehouse.

If a photography shed is built outside the repair shop, it is estimated that it will cost a lot of money. In theory, it should be possible to find a dark warehouse for testing. After all, the arrangement of the headlights, the distance and height, etc., are all available for reference.

"Captain Jiang." The head of the trace inspection team finally tested repeatedly before dawn and came to the conclusion, saying: "It should be a Wuling--"

He took out the headlight photos in the surveillance video and compared them with the headlight photos taken during the test, and took out more than a dozen photos in one breath.

Out of caution, he tested several vehicles many times before making a judgment.

Jiang Yuan only took a quick look and praised it. Then he asked Wang Chuanxing to pass it to the map detection team and asked them to follow the map and look for the vehicle at the nearby vehicle checkpoints.

There is no need for 100% certainty here. In one hour at night, there are so many vehicles passing through the national highway and expressway that it is difficult to check. However, if it is just a certain brand of vehicle, there are not many. Find all of them and see if they are related to the stolen company, and you can basically find the suspect.

Of course, if you still can't find the suspect after checking it once, you have to re-examine the entire process.

A cordon was drawn outside the repair shop, and then the local police station police gave a few words to the boss Qin of the repair shop, and Jiang Yuan and others took the car back.

Before they arrived at the place, the phone call from the picture detective came:

"We found a Wuling that meets the standards at the checkpoint 4 kilometers away from the factory where the crime occurred. After checking, the owner is Wang Jiansheng, who is on the list of resignations!"

Jiang Yuan sat up and said without thinking much: "Catch him. Call Yu Zhi."

"Yes." The picture detective on the other side was even more excited. This case was a pure picture detective case, which was almost completed by the picture detective alone, and it could be used for the annual report.

Jiang Yuan put down his phone, gave instructions to the person next to him, and fell asleep.

Soon, snoring could be heard one after another in the return journey.

Wang Chuanxing opened his eyes with dark circles and sipped his iced Americano silently.
