Chapter 1193 Image Detective Case
Boss Qin, whose real name is Qin Yiming, is 42 years old and is the person in charge of Minghao Repair Shop. Because his wife has divorced him and the child was awarded to her, he lives alone in the shop and manages the daily operation of the shop.
Tonight, Uncle Qin was planning to wash his hands and start watching videos. As soon as he lay down on the bed, he heard a loud knock on the door.
"police!"
As soon as I opened the door, a fierce-looking policeman in uniform showed me his ID.
Before Boss Qin could see clearly, a group of policemen squeezed in. One of them walked in and asked, "How many people live here? Is there anyone else?"
"No more, I'm the only one." Boss Qin replied quickly.
"It's okay. We have a case and need to borrow your car for a while." The instructor from 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."
"You can use it as you like." Boss Qin answered straightforwardly. The luxury cars in the repair shop are inevitably driven out by the mechanics to go for a ride and pick up girls, so it won't hurt to let the police use them.
The instructor of the police station naturally couldn't use it casually in front of a group of city police officers, so he patted Boss Qin on the shoulder and said, "You are thoughtful, and you still have to pay me. You can issue an invoice later, and write Changyang City Criminal Police Detachment on the title..."
This is work for the Criminal Police Brigade, so the expenses will naturally be borne by the Criminal Police Brigade. The instructor does not need Huang Qiangmin to teach, as the basic theories are still available.
Outside the repair shop, Jiang Yuan and others have begun measuring the distance based on the positions in the video.
The quality of the surveillance cameras installed in the factories and repair shops here is very average. They have no night vision function at all, let alone full-color and black light level. They don’t even have ordinary infrared functions, so no vehicle information can be obtained at all.
In comparison, the light beam of a vehicle is more obvious, but it is necessary to confirm the layout characteristics of the headlights in detail, and there are still certain requirements for the clarity of the video. Moreover, it is best to do so 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 features such as cracks on the ground, roadside stones and plants to measure the exact distance as accurately as possible.
Fortunately, what we got was a video, so we can always take more pictures to make corrections.
Once everything that could be measured on the ground had been measured, the police drove over and began to try to analyze the scene.
At this point, it is actually just ordinary trace inspection work.
Ordinary trace inspection and scene reconstruction are mostly experimental in nature. A typical example is whether a body can fit inside a suitcase. It is very simple. Just find someone of similar body size to crawl into it and try it out.
The same is true for surveillance. Trace inspectors first find a few limited locations in the surveillance video to barely determine the location of the vehicle. Based on this, they then park the test vehicle at that location, turn on the headlights, and then based on the width and position of the headlights, they can try to determine whether it is the same type, height, or even the same brand.
After randomly driving a few cars over to try, the person in charge of the trace inspection soon had an idea and reported to Jiang Yuan: "It seems that it should be a small or medium-sized vehicle, and a large truck has basically been ruled out."
"Thank you for your hard work." Jiang Yuan responded with encouragement.
He understands vehicle trace identification, but he doesn't know what each vehicle's headlights will look like. There is no database for this thing, so he can only try it one by one and let other trace detectors test them one by one.
However, he himself could not go to rest. This was somewhat a burden from his fame. If it was more than a year ago, he was just a pure guest military forensic doctor or expert trace investigator, and he only needed to do his job well. But now, for a small case like the theft of dangerous goods, even if an expert team is set up, the team leader must be Jiang Yuan. As the person in charge, Jiang Yuan cannot be too irresponsible.
A group of people stayed in front of the repair shop for another half of the night.
One by one, the borrowed cars were lined up for testing. As for where the cars were borrowed from, it was not a difficult task for the police force.
The trace inspectors responsible for testing are becoming more and more skilled and their speed is getting faster and faster.
Despite this, the expressions of the trace inspectors remained very serious.
The test can only be done at night. It would be troublesome to wait until daybreak to see the traces of the headlights. If we wait for another day and then do 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 greenhouse and the rental requirements of the warehouse.
If we build a photography studio outside the repair shop, it will probably cost a lot of money. In theory, it should be possible to find a dark warehouse to do the test. After all, the arrangement of the headlights, the distance and height, etc., all have numbers for reference...
"Captain Jiang." The head of the trace inspection team finally ran repeated tests before dawn and came to a conclusion, saying, "It should be a Wuling..."
As he spoke, he took out the photos of headlights in the surveillance video and compared them with the photos of headlights taken during the test. He took out more than a dozen photos in one go.
Out of caution, he tested several cars many times before making this judgment.
Jiang Yuan only took a quick look and gave a compliment, then asked Wang Chuanxing to pass it to the Image Reconnaissance Team, asking them to follow the map and look for that type of vehicle at nearby vehicle checkpoints.
There is no need to be 100% sure here. In one hour at night, there are so many vehicles passing through national roads and highways that it is difficult to check. But if we only talk about vehicles of a certain brand, there will not be many. If you find them all and then see if they are related to the stolen company, you can basically find the suspect.
Of course, if after checking once, the suspect is still not found, then the entire process must be re-examined.
A cordon was set up outside the repair shop, and the local police station officers gave some instructions to Mr. Qin, the owner of the repair shop. Then Jiang Yuan and the others drove back.
Before I even got there, Tuzhen called me:
"We found a Wuling car that met the standards at a checkpoint 4 kilometers away from the factory where the incident occurred. Upon investigation, we found that the owner was Wang Jiansheng, who was on the list of people who had left the company!"
Jiang Yuan sat up and said without thinking, "Catch him. Call Yu Zhi."
"Yes." The image detective on the other side was even more excited. This case was a pure image detective case. It was almost completed by the image detective alone and could be used to make an annual report.
Jiang Yuan put down his phone, gave some instructions to the person next to him, and fell asleep.
Soon, on the return journey, snoring sounds could be heard one after another in Costa.
Wang Chuanxing had dark circles under his eyes and sipped his iced Americano silently.
