Chaoyang Public Security Bureau!
Outside the case discussion room!
Liu Qitong, with a sad expression, was still communicating with Zheng Yuanqiao:
"Captain Zheng, the bodies of the three uncles have been found.
But my father..."
"Mr. Liu, we will try our best to find it!"
Liu Qitong suddenly thought of Chen Ting: “That’s right!
That Brother Shen, does he have any clues?
If he can find the Hummer, will he have any ideas about my father's body?"
"this……"
Zheng Yuanqiao didn't dare to say it either.
Because of this case, there is currently no clue pointing to the whereabouts of Liu Furen's body.
But he couldn't understand Shen Ting's method.
So I'm not sure.
Just at this moment!
Chen Ting followed Xiong Beibei and Xu Xinyi to the case discussion room.
When Liu Qitong saw him, his eyes flashed and he asked directly:
“Brother Shen, I have something I want to ask you.
My father's body, do you have any idea?
Here we believe in returning to one's roots, and I'll be feeling uneasy if I can't find my father."
"Ahem, no!"
Shen Ting shook his head decisively.
joke!
Even if I have an idea, I can’t tell you!
Old man, in my opinion, he is now the key suspect.
What’s more, Shen Ting… really has no idea!
When Liu Qitong heard this, he couldn't hide his disappointment in his eyes.
However, he still smiled and thanked Shen Ting:
“Brother Shen, please help me!”
Soon, Zheng Yuanqiao sent Liu Qitong away.
The case seminar officially begins.
The main course is the technical team's forensic doctors, trace detectives, and appraisers reporting their conclusions.
Shen Ting had read the conclusions of the forensic doctor and the trace examination.
The only people who haven't seen it are the evidence examiners who dismantle the car and collect dust, insect fragments, etc.
These have now been identified.
The result is, no result!
No physical evidence was found that could directly identify the murderer.
"The examiner's approach is to try to determine the Hummer's trajectory based on the marks and physical evidence on the vehicle.
Before the car was abandoned, it was determined where the criminals went and what routes they took when they were guerrilla warfare with the investigation team in a Hummer.
Where have you stayed and hidden?
Especially the place where they stopped. If we can find it, we might be able to directly determine the criminal's residence and thus the criminal's identity."
Shen Ting nodded.
This idea is very consistent with the style of a physical evidence examiner.
They usually start from physical evidence and seek breakthroughs.
The key is that it is highly feasible!
For example, the mud and sand collected from car tires are geological evidence.
Based on the forensic geology exchanged last time, Chen Ting determined that if the mud and sand were special enough, it would be possible to restore the complete driving trajectory of the car through them.
certainly!
The difficulty of this operation can be high or low.
The higher the specificity of materials such as sediment, the easier it is to determine the trajectory.
Chaoyang’s own appraisers can also do it.
on the contrary!
The more general the material, the higher the difficulty.
We need to find a more senior appraiser, or even a geology expert, to help.
The mud and sand collected this time belongs to the latter!
“The Hummer is, after all, in that range, fighting guerrilla warfare.
The area is so limited that the gravel in the tires is naturally very similar."
If a vehicle travels long distances, it will 'carry' local special minerals in different places, so it will be relatively easy to determine the trajectory.
“These are all the common mud and sand in southern Chaoyang.
Similar to the previous case, there are glass particles as well.
But there are no things like brine granules that can drastically narrow down the suspects and pinpoint their occupations.”
Shen Ting frowned slightly.
at the same time!
Several technicians quickly completed the report.
Zheng Yuanqiao also frowned:
"Simply put, although there was a lot of evidence collected from the car, nothing directly pointed to the murderer?"
“That’s right!”
“There’s nothing we can do about it!
The interval is too long.”
“Indeed, if we had found this Hummer when the crime happened, we might have found some clues.
But now twelve years have passed, and much of the physical evidence has either decayed and disappeared, or has seriously deteriorated.
Lost its value!"
After hearing the explanations of several appraisers, Zheng Yuanqiao nodded slightly.
Of course he knew all this.
Not to mention twelve years, the golden time for criminal investigation is actually only 72 hours after the crime.
Commonly known as the golden 72 hours!
Because within 72 hours, physical evidence is easiest to collect and witnesses have the clearest memories.
Investigators also have the most energy!
If the case is not solved within the golden time, the difficulty of solving it later will be very high.
Moreover, the longer the time since the crime occurred, the more difficult it is to solve the case.
In 12 years, although the changes are not huge, they can be considered drastic!
Time can dilute too many things, including the truth of the case!
"Everyone, think about this case again. Do you have any other ideas for investigating it?
The Hummer was finally found and the case was finally reopened.
If possible, try to solve the case thoroughly.
Don’t let files sit on the shelf anymore!
Don’t let the victims’ families wait for answers any longer.”
Zheng Yuanqiao spoke sincerely.
The police officers in the conference room were also quite touched and were thinking hard.
But that's how case investigations work.
Many times, hard work alone won’t bring results.
A very promising line of investigation may lead to a dead end.
