Chapter 255： 3rd clue

The leader of the Yuecheng Detective Team, Duan Tianshan, personally sent the results of the second autopsy examination.

For Chen Yan, Duantian Mountain is no stranger.

Broken Tianshan was originally a deputy captain of the Kun City Detective Squad.

Four years ago, he was transferred to the Yuecheng Detective Squad as the top leader.

Although Chen Yan was investigating the strange suicide case in Kun City, Duantian Mountain was no longer there.

However, Duantianshan knows a lot about the legend of Chen Yan.

Not to mention, Wu Yanzhong, the captain of the Kun City Detective Team, mentioned Chen Yan every time when he was having dinner with Duantianshan.

Duan Tianshan had long thought of getting to know Chen Yan.

It's just that Chen Yanyuan is in Liancheng, and it's not that you can see it when you see it.

What Duan Tianshan didn't expect was that in just half a year, not only did he get to know Chen Yan, but now he is still working on a case together.

"Captain Chen, this is the autopsy report!"

Duan Tianshan handed two reports to Chen Yan: "Team Chen, you are truly amazing."

At this moment, Duantianshan, looking at Chen Yan's eyes, is like looking at a monster.

"The black spot is the trace left after being pierced by a very fine gold needle."

"The gold needle itself is as thin as a hair, piercing the skin, no one can feel pain, and the traces left are extremely small."

"You can find out..."

Wu Yanzhong said that Chen Yan's ability to investigate is only seen in his life, and no one can match it.

Duan Tianshan originally thought that Wu Yanzhong was exaggerating.

Maybe it's really powerful, but to say that no one can match it...

However, this time, Broken Tianshan really opened his eyes.

The old detective who performed the autopsy on Zhang Yulin was named Huang Ci. He was 59 years old and had done autopsy all his life.

He is a national treasure of the Yun Provincial Detective Brigade.

When I heard that the Yuecheng Detective Team was going to re-examine the autopsy, I almost jumped up and slashed people.

"If there is any problem with the corpse I checked, you will take off my police uniform!"

If it wasn't for the fact that Wang Min was from the Huaguo Detective Corps, and Chen Yan was the genius who investigated a strange suicide case in Kun City last time, Huang Ci would have killed him and quarreled.

As a result, the old comrade personally conducted a second autopsy overnight.

And it was this second autopsy that Huang Ci took.

No more shouting and fighting.

"In the spinal cords of the third and fourth cervical vertebrae behind the necks of Comrade Zhang Yulin and Jin Nansheng, a residual component of plant sap was detected."

"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 is completely correct.

Accidental fire is an illusion.

The other party first restrained Zhang Yulin, and then anesthetized him into a high paralysis.

After that, Jin Nansheng was robbed, and the electric kettle was short-circuited, causing an electrical fire.

Accidental car accident is also an illusion.

Jin Nansheng had been anesthetized and lost the ability to control the vehicle.

At this time, as long as the other party calculates the time and sets the speed, the car accident may occur.

Of course, this requires very precise calculations.

Two sites, the analysis is completed.

After confirming the nature of the case, this is easy to handle.

I'm afraid, I'm not sure what the nature of the case is.

That Zhang Yulin is not called sacrifice.

Even, because he slept during the shift, not only did Jin Nansheng escape, but also caused a fire.

Lin Gang did the same.

Although an accident occurs in the course of handling the case, it is also a work-related injury.

However, the murderer will escape punishment forever.

【Ding! The task of the strongest police training system is released. 】

[Detection of homicide by accidental means, within ten days, complete the task, reward the trace identification skill specialization, and cancel the task reward if it fails or expires. 】

The nature of the case was finally determined, and in Chen Yan's mind, the prompt to investigate the case sounded simultaneously.

Accidental Means Murder!

Sure enough.

Opponents use hidden means to create accidents that lead to death.

Chen Yan found evidence that the case was not an accident, but a murder.

Therefore, the system also started the reward task.

Trace identification.

Like autopsy, it is a specialized category among detectives.

When Chen Yan went to the police academy, he had this professional learning direction.

According to the internal and external staff, this professional detective actually belongs to the internal staff.

Most of the time, I work in an office.

However, they also go out to work.

When there is a case, the first person to arrive at the scene is actually the detective of the trace identification team.

Collecting on-site evidence, protecting evidence, collecting and analyzing on-site evidence, etc., are all their business.

Chen Yan's Detective Team 2 has five on-site trace identification detectives.

However, this reward is not easy to get.

It has been a long time since Chen Yan encountered a case with a ten-day deadline.

And the time limit given by the system, the longer the time, the more difficult it is to investigate the case.

This time, it seems to be a tough one.

"Leader Wang, the results of the video inspection are out."

The Yuecheng Detective Team, as well as the Yun Provincial Detective Brigade's Major Crime Team, 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 manipulated, Wang Min arranged for someone to check the surveillance video at that time again.

The person in charge shook his head: "As with the previous results, we have expanded the scope of the investigation this time."

"However, nothing has been found yet."

"Half an hour before the crime happened, until the detective arrived after the crime, no suspicious person appeared in the surveillance at that intersection."

Wang Min had already checked the video of the crossroads when he came to the capital Yuecheng.

However, just like the news reported today.

No.

There are no valuable clues.

Chen Yan paused and looked at the person in charge: "Copy the video, I'll watch it myself."

"Yes! Captain Chen!"

Some things can't be found without seeing them in person.

With ten days to handle the case, the difficulty of the case must not be small. Chen Yan has to personally handle a clue every day.

…

ten minutes later.

Chen Yan started watching the video in the office.

January 16, 1:19 pm.

This was the time of the incident.

boom!

In the video, with a loud noise, the two cars slammed into each other.

Jin Nansheng's car flew over Lin Gang's car instantly.

The car rolled directly out of the monitoring range.

Jin Nansheng's car, the front of the car was smashed, white smoke was blowing, and there seemed to be blood on the window after the airbag was deflated.

Rewind the video by half an hour.

It was raining heavily, and the vision was very bad.

In the video, only the traffic lights are flashing and there are no vehicles on the road.

The quiet picture, if there is no wind and rain, seems to be still.

Over time, every minute or two, about a car passed by.

However, at the crossroads, there was not a single person.

This unscientific.

The other party completes the traffic light control by manipulating the control box.

As a result, Jin Nansheng's car and Lin Gang's car all passed at the green light, and finally the illusion of a car accident occurred.

According to the dossier.

The control box of the traffic light has been checked by the serious crime team of the Yun Provincial Detective Brigade.

Wang Min also saw it in person.

After the incident, it was determined to be locked.

Therefore, the other party must have been at the scene when the incident occurred.

In this way, he can re-lock the control box at the first time.

Although the control box is directly under the surveillance camera, it is a surveillance blind spot.

However, the surveillance camera is a 360-degree loop recording and is a spherical surveillance device.

The wide-angle camera is nearly 160 degrees.

Is it possible for the other party to evade the camera?

In theory there is.

For example, it is possible that the person is always following behind the camera, gradually approaching the control box.

However, there is a problem here.

The camera is housed in an anti-reflective black glass cover.

From the outside, the camera is not visible at all.

How does the other party determine the direction of the camera?

How can you be sure that you are on the back of the camera?

Closing his eyes, Chen Yan leaned back in the chair.

Surveillance images flowed rapidly in his mind.

It was raining heavily, and the vision was not clear.

However, within the monitoring range, it is still possible to see whether there is a silhouette.

After the incident, that is, 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 crews arrived.

Between 1:19 and 1:36.

The murderer was only allowed to leave for this period of time after the crime was committed.

According to the questioning of the informant, Li Kangmin, between 1:22 and 1:36, he had been at the scene.

It was this Li Kangmin who rescued Lin Gang from the overturned car.

According to his description, when he was present, he looked around and found no figure.

Then, the murderer should have left three minutes before Li Kangmin's vehicle passed the intersection at 1:22 after the accident occurred at 1:19.

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 and called, the detectives arrived, the ambulance personnel arrived, and all the vehicles left...

Every car, every person, every detail appeared repeatedly in Chen Yan's mind.

At the same time, Chen Yan will also come to two videos of an intersection on the road to compare all the passing vehicles.

There is no village near here,

Therefore, all vehicles must pass through this intersection after passing through the previous intersection.

And if it doesn't pass, then it means that the car must have stopped in the middle of the road.

This is the suspect!

But unfortunately, UU reading www. uukanshu. com is repeated for every car.

And the time is very short, all within the time range of normal driving.

Not only that, the attitude of each car, the gap between the wheel arches and the wheels changes...

and many more!

wrong!

In Chen Yan's mind, there were changes in the heights of the two cars.

What does this mean?

It means that between the last intersection and this intersection, the load of the vehicle has changed!

"Brother Wang," Chen Yan grabbed the phone excitedly after a while: "There is a problem with the two cars!"

"Cha Yunx125789 The owner information of this car, and...the reporter at the time...Li Kangmin's car!" 18428/10775651
