Boss Qin, whose real name is Qin Yiming, is 42 years old and is the person in charge of Minghao Repair Shop. Since his wife has divorced and the child has been given to the woman, he lives alone in the factory and manages the daily operations of the repair shop.
.
Tonight, Uncle Qin planned to wash his hands and start watching videos. As soon as he lay on the bed, he heard a violent knock on the door.
"police!"
When I opened the door, there was a fierce-faced policeman in police uniform showing his ID.
Before Boss Qin could see clearly, a group of police officers squeezed in. Someone walked in and asked, "How many people live here? Is there anyone else?"
"No, it's just me." Boss Qin replied quickly.
"It's okay, we have a case and need to borrow it from your door." The instructor from the local police station came over and talked to Boss Qin in a pleasant manner, and then said: "By the way, you have a lot of cars here, we can rent one for a short period of time."
At night? Give me money."
"You can use it as you like," Boss Qin replied simply. The luxury cars in the repair shop will inevitably be driven out by the repairmen to pick up girls, and even if they are used by the police, they won't lose any paint.
The police station instructor, in front of a group of city bureau policemen, naturally couldn't use it casually. He patted Boss Qin on the shoulder and said: "You are serious. You still have to pay the money. You will issue an invoice later. Look up."
Just write Changyang City Criminal Police Detachment—"
This is work for the Criminal Police Detachment, so the expenses are naturally incurred by the Criminal Police Detachment. The instructor does not need Huang Qiangmin to teach him, but he still has the basic theory.
Outside the repair shop, Jiang Yuan and others had begun to measure the distance based on the location on the video.
The quality of the surveillance cameras installed in factories and repair shops here are very average. They do not have night vision functions at all. Not to mention full-color or black-light cameras, they do not have ordinary infrared functions, so the vehicle information is not available at all.
arrive.
In comparison, the light beam of the vehicle is relatively obvious, but to confirm the arrangement characteristics of the headlights in detail, there are still certain requirements for the clarity of the video, and it is best to do it when the vehicle is moving slowly.
Specifically in this case, it is most appropriate when the vehicle turns in front of the repair shop.
Several trace detectors used features such as cracks in the ground, roadside stones, and plants to measure the exact distance as accurately as possible.
Fortunately, the video is obtained, so you can always measure it several times to correct it.
When everything that can be measured on the ground is clearly measured, the police will drive over and start trying on-site analysis. At this point, it is actually an ordinary trace inspection work.
Ordinary trace inspection and restoration sites are mostly experimental in nature. A typical example is whether a suitcase can fit a corpse. It is very simple. You just need to find someone of similar stature to get in and try it.
It’s the same when watching surveillance. The trace inspectors first find a few limited locations in the surveillance video and can barely determine the location of the vehicle. Based on this, they park the test vehicle at that location, turn on the headlights, and then based on the headlights
By looking at the width and position, you can try to determine whether they are of the same type, height or even brand.
I randomly drove a few vehicles over and gave it a try. The responsible trace inspector soon had an idea and reported to Jiang Yuan: "Now it seems that it should be a small and medium-sized vehicle, basically excluding large trucks."
"Thank you for your hard work." Jiang Yuan encouraged him.
He understands vehicle mark identification, but he doesn't know the specific appearance of each vehicle's headlights. There is no database for this thing, so he can only try it one by one and let other mark inspections test one by one.
It's just that he himself can't go to rest. This is somewhat tired of his fame. If it were more than a year ago, he would have been a purely foreign forensic doctor or expert during the trace examination. He only had to do his best.
Can.
But nowadays, for small cases such as the theft of dangerous goods, even if an expert team is established, the team leader will definitely be Jiang Yuan. As the person in charge, Jiang Yuan would be very irresponsible.
A group of people stayed up for another half of the night in front of the repair shop.
Borrowed cars were lined up to be tested. As for where the cars were borrowed from, it was really not a difficult task for the police force.
The trace inspections responsible for testing are becoming more and more proficient and faster.
Despite this, the expressions of several trace examiners were still very serious.
The test must be done at night. It will be troublesome to wait until daybreak to see the traces of the headlights. Wait for another day,
If you do the test again, the delay will be a bit long.
Wang Chuanxing next to him also thought of the same problem. While yawning, he began to silently inquire about the rental price of the photography studio and the rental requirements of the warehouse.
If you build a photography booth outside the repair shop, it will probably 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, distance and height, etc.
, there are also numbers for reference.·
"Team Jiang." The person in charge of the mark inspection team, before dawn, finally tested repeatedly and came to the conclusion, "It should be a Wuling——"
As he spoke, he took out the photos of the headlights in the surveillance video and compared them with the photos of the headlights taken during the test. He took out more than a dozen photos at once.
Out of caution, he made his judgment after testing many times and several vehicles.
Jiang Yuan only took a cursory look, praised it, and then asked Wang Chuanxing to transfer it to the map scout team, asking them to search for this type of vehicle at nearby vehicle bays according to the picture.
There is no need to be 100% sure here. There are so many vehicles passing through national highways and highways in one hour at night that it is difficult to check. But if you only refer to vehicles of a certain brand, there are not many. Find them all and see how they relate to each other.
Whether the stolen company is related or not, the suspect can basically be found.
Of course, if you still can't find the suspect after checking, then you need to re-examine the entire process.
A warning tape was placed outside the repair shop, and the police from the local police station gave a few words of warning to Boss Qin of the repair shop. Jiang Yuan and others returned by car.
Without waiting, a call came from the picture detective:
"We found a Wuling that met the standards at a checkpoint 4 kilometers away from the factory where the crime occurred. After investigation, the owner of the car was named Wang Jiansheng, and he was on the resignation list!"
Jiang Yuan sat up and said without thinking, "Arrest the person. Call Yu Zhi."
"Yes." The picture detective on the other side was even more excited. This case is a pure picture detective case. It was almost completed by the picture detective alone. It can be used for annual reports.
Jiang Yuan put down his cell phone, told the person next to him, and fell asleep.
Soon, on the way back to Costner, snoring began one after another.
Wang Chuanxing opened his eyes with dark circles and silently sipped the ice cream.
