Chapter 255: The third clue
The captain of Yuecheng's detective team, Duan Tianshan, personally delivered the results of the second autopsy.
Duan Tianshan was no stranger to Chen Yan.
Duan Tianshan, originally served as the deputy captain of the Kunming Criminal Police Team.
Four years ago, he was transferred to the Yuecheng Criminal Police Team as the leader.
Although Chen Yan was investigating the weird suicide case in Kunming, Duan Tianshan was no longer there.
However, Duan Tianshan knows a lot about Chen Yan's legend.
Among other things, Wu Yanzhong, captain of the Kunming City Criminal Police Team, mentioned Chen Yan every time he had dinner with Duan Tianshan.
Duan Tianshan had long thought of getting to know Chen Yan.
It's just that Chen Yanyuan is in Liancheng, so it's not like he can see you just by seeing him.
What Duan Tianshan didn't expect was that in just half a year, not only did he get to know Chen Yan, but now they are still handling the case together.
Captain Chen, this is the autopsy report!
Duan Tianshan handed the two reports to Chen Yan: Captain Chen, you are really amazing.
Duan Tianshan at this moment looked at Chen Yan as if he was looking at a monster.
That black spot is the mark left after being pierced by a very thin gold needle.
The gold needle itself is as thin as a hair, piercing through the skin, no one feels pain, and the traces left are even more minimal.
You can find this...
Wu Yanzhong said that Chen Yan's investigation skills were the only ones he had seen in his life, and no one could match them.
Duan Tianshan originally felt that Wu Yanzhong was exaggerating.
Maybe it's really powerful, but to say that no one can match it...
However, Duan Tianshan really opened his eyes this time.
The old detective who performed the autopsy on Zhang Yulin was called Huang Ci. He was 59 years old and had done autopsy all his life.
He is a national treasure figure of the Yun Province Criminal Investigation Brigade.
When I heard that the Yuecheng detective team was going to re-examine the autopsy,
Almost jumped up and cut people.
I checked the corpse, if there is any problem, you will take off my police uniform!
If it weren't for knowing that Wang Min came from the Huaguo Criminal Police Corps, and that Chen Yan was the genius who investigated the weird suicide case in Kunming last time, Huang Ci would have killed him and quarreled.
As a result, the old comrade personally conducted the second autopsy overnight.
And it was this second autopsy that Huang Ci accepted.
No more shouting and fighting.
At the back of the necks of Comrade Zhang Yulin and Jin Nansheng, a residual component of a plant juice was detected in the spinal cord in the third and fourth cervical vertebrae.
And this juice has a strong anesthetic effect.
In Yun Province, many farmers will use this kind of thing to relieve pain.
Real hammer!
Wang Min and Chen Yan looked at each other.
Chen Yan's reasoning was completely correct.
An accidental fire is an illusion.
The opponent first restrained Zhang Yulin, and then anesthetized him into a high paralysis.
After that, Jin Nansheng was robbed, and then the electric kettle was short-circuited, causing an electrical fire.
An accidental car accident is also an illusion.
Jin Nansheng had been anesthetized at that time and lost the ability to control the vehicle.
And at this time, as long as the other party calculates the time and sets the speed, the accident may happen.
Of course, this requires very precise calculations.
The analysis of the two scenes is complete.
Once the nature of the case is confirmed, it's easy to handle.
Just be afraid, the nature of the case cannot be determined.
That Zhang Yulin is not called sacrifice.
Even, because of sleeping during the shift, Jin Nansheng not only allowed Jin Nansheng to escape, but also caused a fire.
The same is true for Lin Gang.
Although there was an accidental car accident during the case, it was considered a work-related injury.
But the murderer would always get away with it.
【Ding! The task of the strongest police training system is released. 】
[Detection of murder by accidental means has a deadline of ten days. Complete the task and reward trace identification skills specialization. If you fail or exceed the deadline, the task reward will be cancelled. 】
The nature of the case was finally determined. In Chen Yan's mind, the prompt for investigating the case sounded simultaneously.
Murder by Accidental Means!
Sure enough.
The opponent uses hidden means to create accidents and cause death.
Chen Yan found evidence that the case was not an accident, but a murder.
Therefore, the system also started a reward task.
trace identification.
Like autopsy, it is a professional classification among detectives.
When Chen Yan was in the police academy, he had this major to study.
According to the internal and external affairs, this professional detective actually belongs to the internal affairs.
Most of the time, I work in an office.
However, they are also out in the field.
When there is a case, the person who arrives at the scene immediately is actually the detective of the trace identification team.
Collecting evidence at the scene, protecting the evidence, collecting and analyzing the evidence at the scene, etc., are all their business.
Chen Yan's Second Detective Team had five on-site trace identification detectives.
However, this reward is not easy to get.
It had been a long time since Chen Yan had encountered a case with a deadline of ten days.
The longer the time limit given by the system, the more difficult it is to investigate the case.
This time, it seems to be a tough one.
Team Leader Wang, the results of the video inspection are out.
The Yuecheng Criminal Police Team, as well as the Serious Crime Team of the Yun Provincial Criminal Police Brigade, have been divided into several working groups by Wang Min.
How is it, is there anything unusual?
Yesterday, after discovering that the traffic light control box had been tampered with, Wang Min immediately arranged for someone to check the surveillance video at that time again.
The person in charge shook his head: Same as the previous results, we have expanded the scope of the investigation this time.
However, nothing was found.
Half an hour before the incident, and after the incident until the detectives arrived at the scene, no suspicious person appeared on the surveillance at that intersection.
Wang Min had checked the video at the crossroads when he came to Duyue City.
However, just like the news reported today.
No.
There are no clues of any value.
Chen Yan paused, then looked at the person in charge: Copy the video, and I'll watch it myself.
Yes! Captain Chen!
Some things, if you don't see it yourself, you can't find the problem.
Ten days to handle the case, the case must be quite difficult, Chen Yan has to personally handle one clue per day.
...
ten minutes later.
Chen Yan started watching the video in the office.
January 16, 1:19 p.m.
This is the time when the incident occurred.
boom!
In the video, with a loud noise, the two cars collided fiercely.
Jin Nansheng's car instantly knocked Lin Gang's car into the air.
The car rolled directly out of the monitoring range.
The front of Jin Nansheng's car was shattered, and white smoke was blowing out. On the window, there seemed to be blood sprayed after the airbag deflated.
Rewind the video by half an hour.
It was raining heavily and the visibility was very poor.
In the video, only the traffic lights are flashing, and there are no vehicles on the road.
The quiet picture, if there is no sound of wind and rain, seems to be still.
Time goes by, every one or two minutes, about a car passes by.
However, there was no one at the intersection.
This unscientific.
The other party completes traffic light control by tampering with the control box.
As a result, both Jin Nansheng's car and Lin Gang's car passed when the light was green, and finally there was an illusion of a car accident.
According to the dossier records.
The control box of the traffic light was checked by the serious crime team of the Yunnan Provincial Criminal Police Brigade.
Wang Min also saw it in person.
After the incident, it was determined to be locked.
Therefore, when the crime happened, the other party must be at the scene.
In this way, he could re-lock the control box in the first place.
Although the control box is directly under the monitoring camera, it is a monitoring blind spot.
However, the surveillance camera is a 360-degree loop recording, which is a spherical surveillance device.
The wide angle of the camera is nearly 160 degrees.
Is it possible for the other party to escape the camera?
In theory there is.
For example, it is possible for this person to always follow the camera and gradually approach the control box.
However, there is a problem here.
The camera is mounted in an anti-reflective black glass cover.
From the outside, the camera is not visible at all.
How does the other party judge the direction of the camera?
How can you ensure that you are on the back of the camera?
Closing his eyes, Chen Yan leaned back in the chair.
Surveillance images flowed rapidly in my mind.
Heavy rain, vision is not clear.
However, within the monitoring range, it is still possible to see whether there is a human figure.
After the incident, at 1:22, a car passed by.
Li Kangmin, the driver of the car, called the police.
At 1:36, the detective who received the report arrived at the scene.
At 38 minutes, ambulance personnel arrived at the scene.
Between 1:19 and 1:36.
After the murder, only this time can leave.
According to the inquiry of the reporter Li Kangmin, he was at the scene from 1:22 to 1:36.
It was also Li Kangmin who rescued Lin Gang from the overturned car.
According to his description, when he was present, he looked around and found no one.
Then, the murderer should have left after the car accident at 1:19 and before Li Kangmin's vehicle passed the intersection at 1:22.
three minutes!
Chen Yan watched the three-minute video over and over again, but never found anything.
This is so unscientific...
Three minutes after the incident, Li Kangmin's car arrived at the scene, Li Kangmin got out of the car to make a phone call, detectives arrived, ambulance personnel arrived, and all vehicles left...
Every car, every person, and every detail recurred in Chen Yan's mind.
At the same time, Chen Yan also uploaded a video of an intersection on two roads to compare all the passing vehicles.
There is no village near here,
Therefore, after all vehicles pass the previous intersection, they will definitely pass through this intersection.
And if it didn't pass by, it means that the car must have stopped in the middle of the road.
This is the suspicion!
But alas, every car is repeated.
And the time is very short, all within the normal driving time range.
Not only that, each car's stance, fender flares and gaps between the wheels vary...
wait!
wrong!
In Chen Yan's mind, there were changes in the height and posture of the two cars.
What does this mean?
Explain that between the previous intersection and this intersection, the load of the vehicle has changed!
Brother Wang, Chen Yan picked up the phone excitedly after a while, There is a problem with the two cars!
Zha Yun x125789 the owner information of this car, and... the reporter at the time... Li Kangmin's car! 18428/10775651
