Chapter 56： new clues

A total of nine airtight bags were found outside the guard fence, and even on the big tree in the corner of the fence.

Only the size of a thumb, there is a transparent liquid inside.

"Send it to the test immediately, compare the DNA sequence, if it is from the same person, report it immediately, and prepare for arrest!"

Wang Shun really accepted it.

Famous is indeed better than meeting.

On my side, there are dozens of people, and they haven't noticed it for three days.

Until now, there are still a large group of brothers wandering in the mountains.

But it took less than half a day for people to come, so it should take four or five hours.

Investigating the scene, I found hair clues, and after a trip to the first guard, I found the means of Zhang Xiaohua's pregnancy.

People are really incomparable.

…

When Chen Yan and Wang Shun returned to the Iron City Detective Team, everyone had finished resting.

They slept all afternoon, and they were all full of energy.

In particular, they had heard that Chen Yan had discovered two important clues in less than an afternoon, and they were all excited.

Leading a team, the most important thing is spirit.

In the past three days, everyone worked day and night, but they didn't find it at all.

As a police officer, you are not afraid of overtime and tiredness.

But they are afraid of the ineffectiveness of their work, the blood of their sacrificed colleagues, and they are powerless.

Well now, Chen Yan came and gave everyone a big dose of stimulant.

As soon as Chen Yan entered the conference room, everyone couldn't help cheering.

Chen Yan waved his hand: "This is just the beginning, and the next time is to fight a tough battle. I hope everyone will persevere."

"Now, do you have the confidence to catch these bastards?"

"Have!"

This is the spirit of the detective team.

At noon, when Chen Yan first arrived, at a glance, there were quite a few people, but all of them had strong fighting spirit and had no fighting power at all.

"Bring me the video data of the main road leading to the first guard branch road before and after the incident."

When investigating the scene in the afternoon, Chen Yan knew that the other party must be a long-planned prisoner.

Judging from the existing evidence, Wang Lili has a high probability of participating in the crime of robbing prisoners.

And, it played a key role.

After all, Zhang Xiaohua has not been exposed to outside information since two years ago.

According to this reasoning, the time when they started planning should be three months ago, when Wang Lili was in prison.

Even, the reason why Wang Lili was imprisoned was to carry out this robbery.

Because, all the female prisoners who were detained and sentenced in Tieshi were executed in the first prison of Tieshi.

Once Wang Lili enters the prison, she will definitely be able to get in touch with Zhang Xiaohua.

Although Wang Lili was in prison for three months without contact with outsiders, she could have planned the robbery plan in advance.

Since the other party can deliver bodily fluids through the high-altitude drone and make Zhang Xiaohua pregnant, they can naturally observe the situation on the ground through the high-altitude drone mounted with a high-definition camera.

Once Wang Lili confirms that Zhang Xiaohua is pregnant, she can use gestures and other fixed actions to notify people outside and start a prison robbery plan.

As for why Zhang Xiaohua couldn't wait for eight months, Chen Yan didn't know.

However, there are no directional clues now, so Chen Yan can only temporarily give up exploring.

The video data on the main road, Wang Shun and the others collected it early in the morning.

"The surveillance video of this main road is part of the Sky Eye system, and the storage period is very long. We have reviewed the video for nearly a month."

Wang Shun handed the video to Chen Yan and reported their findings at the same time.

"This road is the main road, and the traffic flow is relatively large..."

While watching the video, Chen Yan analyzed the situation of the perpetrator in his mind.

The other party murdered in the ambulance, neatly and neatly, leaving almost no trace, except for a strand of yellow hair.

Moreover, the other party didn't kill the driver, is it because the other party was kind?

Absolutely not!

What is that for?

One was that the other party was in a coma, and the driver didn't see their faces.

Is there any other reason?

What if the driver pretended to be unconscious?

So, there must be other reasons, so they don't have time to kill...

right!

time!

The other party must be in a hurry.

However, if the other party ran into the mountains, would he need to be in such a hurry?

Need not!

Running on two legs, it takes half a minute to kill a person.

Moreover, the other party actually delivered bodily fluids through a high-altitude drone, making Zhang Xiaohua pregnant, and letting Wang Lili deliberately commit a crime into the first prison to help Zhang Xiaohua escape the prison.

So can the other party not have a complete retreat plan after killing and robbing prisoners?

impossible!

Therefore, there is a high probability that they will not run up and down, but will leave on the main road in a car swaggeringly.

The question is, what car will they take to leave?

You know, after the ambulance leaves the first guard, it must report the situation every three minutes.

Therefore, the first guard started emergency measures immediately after the incident.

Ten minutes after the incident, they arrived at the scene and immediately reported to the Iron City Detective Team.

All passing vehicles on the main road have been tracked and checked, but no abnormality has been found.

"Team leader," Wang Shun pointed at the screen: "Three days ago, during the time of the incident, a total of 298 vehicles passed by."

Wang Shun has studied the video for a long time, so he is very clear about the relevant data: "There are 168 sedans, 54 off-road vehicles, and 76 container trucks."

…

Chen Yan, who opened the visual gene lock, is like a projector at the moment.

The 298 vehicles in the time period of the crime were immersed in their minds, and then compared with all the vehicles that passed by in a month. UU Reading

Since the other party is an organized robbery prisoner, they will definitely step on it in advance.

And more than once or twice.

In this way, after comparison, within 30 days, the number of vehicles passing through this main road was greatly reduced.

56 vehicles passed more than twice.

Among them, 27 vehicles are sedans and off-road vehicles, which pass here every day.

Most likely it is a commuter car.

There are also 24 other vehicles, which have appeared between two and thirteen times.

This is what Chen Yan focused on.

The rest are 5 container trucks, which also pass here every day.

"Wang Shun, these 24 sedans and off-road vehicles will be checked again." After handing over the selected vehicles to Wang Shun, Chen Yan pointed to the five container trucks in the video: "I will personally find these five vehicles. Go check it out!"

Check it out for yourself?

Wang Shun was taken aback, knowing that Chen Yan was suspicious of these five cars.

At this moment, Wang Shun arranged to send the results of the test for yellow hair.

Wang Shun handed the test report to Chen Yan: "Team leader, the result is out, it's a feather!"

Taking the test report, Chen Yan stared at the vehicle on the screen while looking at the test sheet.

"Is there a beef processing factory or a farm nearby?"

"Well," a young detective on the side nodded: "Team Leader Chen, the first guard is to the southeast. There is a beef processing factory about five kilometers away."

The detective pointed to one of the five container trucks that were frozen on the screen and continued: "This is the truck they use to transport frozen beef."

Um?

Chen Yan was slightly startled.

Immediately, there was a gleam in his eyes.

This time, it was a provincial investigation.

"Let's go, beef processing factory!"
