Chapter 251： 1st clue

Wang Min looked at Chen Yan in disbelief.

Wang Min himself had seen the control box, but he really didn't find anything.

However, after just squatting there for two minutes, Chen Yan discovered the problem.

Moreover, Chen Yan also asked himself to see it.

However, even so, Wang Min didn't see anything.

this……

Don't blame Wang Min.

The safety button is inserted vertically into the fuse box.

The dust on each button is pitiful.

If Chen Yan hadn't turned on the visual gene lock, it would have been impossible to find the difference between that button and other buttons.

"That insurance button is the insurance that controls the traffic light switch in the direction of Chang'an Road."

"If the contact is poor, it will cause the green light to be delayed."

Sure enough!

"That is to say, when the car accident happened that day, someone was controlling the control box of the traffic light."

"The other party did not directly toggle the traffic light control switch, but loosened the insurance button, causing a delay in the green light in the direction of Chang'an Road."

"In addition, Jin Nansheng's car stopped by the road twice..."

It was clearly a deliberate car accident that was carefully planned and timed to the level of seconds.

It's just that the other party's packaging is too perfect, leaving almost no flaws.

Although Wang Min knew that this could not be an accident, but due to the lack of evidence, he was unable to finalize the case.

Now, with the evidence, the nature of the case can be determined.

Even this evidence still cannot point to any suspects.

However, this is of great significance to Lin Gang.

Without Chen Yan's discovery, Lin Gang was in an accidental car accident.

With this evidence, it was intentional murder, what was wrong with Lin Gang, and the concept of accidental death was different.

"Chen Yan, I thank you on behalf of Lin Gang!"

"Brother Wang, why are you being polite to me?"

With the clues, without Chen Yan's arrangement, Wang Min's side made the deployment immediately.

A comprehensive investigation of the surveillance near the intersection that day.

Let's see if you can find the guy who rigged the control box.

Wang Min himself has actually seen the video.

no problems found.

This time, I rechecked it again, and the point was to see if I could find someone who was tampering with the traffic light control box.

Half an hour later, the Panshui Town Detective Team.

The current Panshui Town Detective Team has become a ruin.

"The fire that day destroyed all traces at that time."

Wang Min began to introduce the previous survey.

"From the analysis of the fire point, the place where the fire first started was in the duty room where Zhang Yulin was sitting."

"It was a fire caused by a short circuit in the electric kettle."

Kettle short circuit?

"The fire time was after 2 o'clock at night, right?"

Chen Yan observed carefully in the ruins: "At that time, the kettle was still working?"

"I checked some information, and the kettles of the Panshui Town Detective Team are all configured uniformly."

"This electric kettle can set the water temperature. Once the water temperature is lower than the set value, the electric kettle will start to work."

Chen Yan nodded and continued to observe.

Chen Yan has already studied the relevant files on the road.

The fire started at 2pm on the 5th.

The original fire place was Zhang Yulin's office.

Next to the duty room is the gun room.

Inside were two pistols with 20 rounds of ammunition.

There are also explosion-proof clothing, shields, electric batons, handcuffs and other equipment.

None of these things were lost.

But in the fire, they were all destroyed.

Electrical fires are different from general fires.

Once it is burned, and no measures are taken in time, the harm caused is very great.

The house of the Panshui Town Detective Team is also a bungalow with a lot of combustibles on the roof.

Plus the interior decoration and furniture and so on.

After the fire started, the fire was very big.

"Brother Wang, are you sure about the cause of Zhang Yulin's death?"

Wang Min nodded.

Chen Yan's problem was also the first thing he needed to know when he arrived at the Panshui Town Detective Team.
