Chapter 530 Two Iron Plates

Fifteen years!

fifteen years!

This is the only evidence found at the scene of the serial murderer!

Although it does not necessarily belong to the murderer, because under normal circumstances, only the driver can access this place.

However, no matter whose fingerprints it is, it shows that the murderer did not completely remove all traces from the driver's seat.

With fingerprints, there are likely to be other clues!

The driver's seat itself is not very spacious, and Chen Yan was watching from the co-pilot's side. There was only one investigation detective at the scene, and there was another investigation detective beside him.

The time was actually 4 o'clock in the afternoon.

Since the cement factory was relocated five years ago, it has never been as lively as it is today.

On the gravel ground, Chen Yan, Wang Fenglei and others were waiting for the final investigation clues from the driver's seat. In the factory area, it was not just the more than 20 people who were looking for the cardboard or iron plates that the murderer might have discarded. More than three hundred people are searching here.

Wang Fenglei was also ruthless and sent all the people from the Shen City Detective Team who had no cases yet to come here to look for clues.

You know, these detectives are not those who sit in the office and do internal work, but they are all detectives who work in the field.

In the entire Liao Province Detective Brigade, only the Shen City Detective Team has such a large hand, and can eliminate more than 300 field detectives at once.

In the Liancheng Detective Team, there are not so many field detectives.

The sky was getting dark, but Wang Fenglei, Chen Yan and others were not impatient at all.

Because there was a new discovery in the driver's seat.

After the blood coagulated, the detectives cleaned up the blood covering the foot pad bit by bit and found very clear footprints at the bottom.

And it's not separate, but overlapping footprints.

One pair belonged to the deceased, and the other pair was most likely the murderer.

"Team Wang, Brigade Wang!"

Wang Fenglei was currently outside the car staring at the investigation detectives inside looking for clues, and the intercom at his hand sounded a call request.

"I am Wang Fenglei!"

Turning on the intercom, Wang Fenglei looked a little excited, because it was Wang Kun, deputy captain of the Shen City Detective Team, who made the call request!

Wang Kun has also dealt with Chen Yan. He is the deputy captain in charge of case investigation work of the Shen City Detective Team, and his position is similar to Chen Yan.

In the afternoon, Wang Kun led more than 300 people in the factory area to look for paper shells or iron plates or other things that the murderer might have used for footings.

"Captain Wang, I am Wang Kun!"

On the intercom, Wang Kun's voice was trembling.

Even Chen Yan, who had been in the co-pilot, sounded like something was wrong.

After pushing himself up and getting out of the passenger seat, Chen Yan stared at Wang Fenglei's intercom.

"We found items suspected to have been abandoned by the murderer in an abandoned crushing tank in the northeast corner of the factory!"

Found?

"Wait for me! I'll go there now!"

Wang Fenglei's expression at this moment can no longer be described as excitement.

Totally excited!

The veins are exposed and the eyes are shining!

Chen Yan had met Wang Fenglei several times, and he couldn't be said to be very familiar with Wang Fenglei. However, as the deputy captain of the Liao Provincial Detective Brigade, Wang Fenglei still had official authority.

Even if Qin Chuan hadn't been parachuted from the Liancheng Detective Team, then after Captain Liu Jinsong was promoted last year, according to normal procedures, Wang Fenglei would have taken over Liu Jinsong's position.

Such a big leader is definitely a person who shows no emotion or anger when facing his subordinates.

Just like the leaders Chen Yan had seen in the Beijing Detective Corps, none of them were calm and dignified.

There are very few people who can be leaders who can't keep their composure.

Therefore, since Wang Fenglei showed such a shocked and excited expression in front of so many people, it can be seen that there must be a storm in his heart.

However, Chen Yan can understand it if he puts himself in his shoes.

Chen Yan has only been in the police for two years so far, but what about Wang Fenglei?

It can be said that I have spent most of my life in the detective team.

As for a serial murder case that he personally handled fifteen years ago, now that there is hope of investigation, Wang Fenglei is not excited, which is why there is a problem.

"Team Leader Chen, let's go over and take a look!"

Chen Yan nodded, the work here is a meticulous process, and the extraction of footprints is not done overnight.

The two pairs of footprints under the blood were partially superimposed on each other.

Moreover, because the driver's feet were fixed to the floor mat before being bled, there was a part in the middle that was not contaminated by blood.

Therefore, the process of separation survey must be very careful and meticulous.

Because every detail discovered below may become the ultimate hope for solving the case.

five minutes later.

Chen Yan and Wang Fenglei rushed to the northeast corner of the cement factory.

There are ten huge crushing tanks here, which should have been used for secondary crushing of stones.

The production of cement is actually very simple. The main raw material comes from stone.

After huge rocks are mined, they must be initially crushed and then subjected to secondary crushing.

These crushing tanks are secondary crushing machines.

Wang Kun did not come up to greet Chen Yan and Wang Fenglei at this moment.

Instead, he takes command in front of Smash Tank No. 10.

"Be careful and stay safe!"

From afar, Chen Yan and Wang Fenglei heard Wang Kun's voice.

"How's it going?"

Walking closer, Wang Fenglei looked into the crushing tank. Only then did Wang Kun realize that Wang Fenglei had arrived: "Right now, this crushing tank is very deep. We just hoisted people in with ropes..."

It turned out that the detective who had just been responsible for searching this area had searched everywhere, but still found nothing.

Just when everyone was about to give up, a bat that was in the crushing tank suddenly flew out, possibly frightened, and this attracted the attention of the detectives.

After searching through the ten crushing cans one by one, I finally found something!

"Captain! We got the stuff!"

While Wang Kun was reporting, a huge echo came from the crushing tank.

"Captain, found it!"

Ten minutes later, the detective who went down to look for things finally came up.

"Team Wang, look, this is it!"

The detective responsible for entering the jar to retrieve the items wore gloves and handed two rusty iron plates to everyone.

Chen Yan and Wang Fenglei just took a look and were sure that this was it.

Because there happened to be emerald green grass pulp residue on one side of the iron sheet.

"Take it back immediately for examination!"

Chen Yan judged this thing well. The iron plate was rectangular, less than 10 centimeters wide, but each piece was about 30 centimeters long.

The width of the two iron sheets was no more than the width of the tires, just enough to fit in the rutted channel, and long enough for the murderer to step on them with both feet.

Judging from the rust on it and the traces of cement adhesion, this thing was most likely found by the murderer in the cement factory.

The cement factory area was a location carefully chosen by the murderer, and the entire crime process should also have been deliberately planned by the murderer.

The murderer drove the car into the cement factory area, chose a gravel clearing as the crime site, then erased all traces in the car, and then used two iron plates to leave along the rutted passage.

Then he threw the iron plate into the crushing tank. Everything was planned by the murderer.

Therefore, Chen Yan speculated that it was unlikely to detect the fingerprints or other information of the deceased on the two iron plates.

Since the murderer had removed all traces inside the vehicle, how could he have left a flaw in the iron plate?

At the very least, he would definitely wear gloves when using and discarding iron plates.

Because the murderer knew that he could not completely destroy these two iron plates, and they might be discovered if they were abandoned in the factory area.

Of course, this possibility is very small.

If it weren't for Chen Yan's visual gene lock, he wouldn't have been able to discover that the murderer had left the grass circle in this way.

However, judging from the murderer's level of caution, he would not have carelessly touched the iron plate directly with his hand, leaving a flaw in case of any eventuality.

As for the footprints, they are also difficult. This is an iron plate, and people will not leave any traces when they step on it.

However, just because there were no footprints, it didn’t mean that nothing else was left behind.
