However, since the Hummer's dashcam was damaged, we can only rely on the physical evidence in the car to try to restore the trajectory.
Thinking of this, the police officers frowned.
This idea is indeed fine, but the problem is!
How to restore the trajectory?
Based on which physical evidence, can we restore the trajectory?
The technical staff attending the meeting shook their heads directly:
“We’ve tried this method before, but it doesn’t work!
The most commonly used method to restore the driving track is to use sand and gravel on the tires.
However, the criminals had cleaned the tires, and the remaining sand and gravel were not specific enough.
You may not know that within a small area, the trajectory can be determined by sand and gravel.
It has to be combined with the mixed fibers, paint fragments, glass fragments, etc.
But the amount of material found in the gaps between the tires was too small to be enough to restore the track."
"The insect remains are too corrupt.
Even if the corruption isn't severe, it's difficult to determine the car's trajectory within a small area using insects."
“The pollen in the car is okay.
But it’s the same problem as with insects. After twelve years, there are too few left.
Otherwise, we can really ask a pollen expert to try to restore the trajectory.
Our technical team has already considered these things.”
Zheng Yuanqiao frowned.
Doesn't Shen Ting's method work?
Is this case going to be shelved again?
Thinking of the sorrow in Liu Qitong's eyes and the wailing of the families of the three deceased, Zheng Yuanqiao felt a little annoyed.
He subconsciously took out a cigarette, but there were non-smokers in the meeting room, so he didn't light it, but just put it under his nose and smelled it.
The other police officers also frowned and fell silent.
"Cough~~"
At this time!
A dry cough suddenly sounded.
The voice was not loud and seemed a little reserved, but in the conference room where one could hear a pin drop, it was like a huge bell.
Everyone looked over and saw Shen Ting raising his hand again:
"Well, Captain Zheng, the reason I brought up this idea is that I can actually try to reconstruct the Hummer's trajectory."
