"This morning, how many cars are pulled away from the 9th mixing station?"

"This ..." The man thought about it: "It's not easy to say, we can fill a mixer car in 16 minutes, this specific amount ... not easy to calculate."

"However, the construction site of the concrete mortar of each mixing station is fixed."

"Let's check the car list and know."

Soon, the outlets of the 9th mixing station were sent to Chen Yan.

From 12 am today to the present, 12 hours, the 9th mixing station transported a total of 45 vehicles concrete.

According to the corpses found at the site of the Wanghai Building and the Kangmingyuan residential building project, combined with the No. 9 mixing station, it has not stopped running. The time for the murderer to throw the corpse should be very close to the current time.

The first time I found the head was 8:25 am, and then I found that the time for the right arm was 9:08.

Chen Yan took the surroundings and only found that there was a camera at the place where the company was imported.

Chen Yan looked at the person in charge of the scene: "Does your company only have the camera at the door?"

"Two, in addition to this financial room, there is one, but only the camera of the financial room."

"The dust of the crushed stone on our side is particularly large. I have installed a lot of cameras before, and it will be broken within a few days.

No camera ...

"How many people do you work here at night?"

"We are two shifts, because the mixing stations are automatic, so we don't need many people."

The person in charge was named Zhang Hui, pointing at the mixing station: "Things such as the mixing station, the mortar label produced by each mixing station is fixed.

I can stir it by myself. "

"Our mixing station of our distant commercial company has been renovated last year.

"The ingredients of the cone barrel are also controlled by electric, not using people to operate, so there are not many people who use it. There are 6 people in each class, and the mixing station can work normally."

When Chen Yan entered the yard, he had carefully observed other mixing stations that were still working.

As Zhang Hui said, the degree of automation of the mixing station is very high.

There is only one place in the entire production session that requires manual participation, that is, the addition of stone.

There are shovel in the shovel into the crusher from time to time, and the other processes are automatically completed.

Chen Yan walked into the 9th mixing station and observed carefully.

The entire cone bar can only have a pulp below, and other places are sealed.

The stone conveyor belt is also sealed on the upper right. It is also sealed.

So, how does the corpse enter this cone stirring barrel?

It is impossible in the crushing machine, because the stone particles stored here are relatively large, the standard size required for crushing into a mortar will be transported into the mixing cone bar.

Chen Yan looked at it, probably the size of the nail lid.

If the corpse puts it in from it, it will have been shattered long ago.

And the mixing bucket is sealed again ...

Therefore, there is only one place that can put the body in.

Transfer belt.

"Can this pass to a protective cover can be opened?"

Zhang Hui nodded: "Of course, this protective cover is to prevent debris from entering, and there is to prevent stone from pouring."

… "Because the bearings under the transfer belt need to be maintained frequently, this protective cover is not welded, it is divided into break, it can be easily removed."

"Come, come over, take this protective cover."

Behind Zhang Hui, the two guys in the blue labor suit hurried forward, perhaps because they worked in the dusty venue for a long time.

Both young men's hair was gray, and even a layer of lime powder was sticky on the eyebrows.

The two guys stood on both sides of the protective cover, with one less force, and a protective cover was unveiled.

"this......"

Seeing the scene in the protective cover, Zhang Hui and others were scared and retreated.

Dangda!

Even a young man was not scared, and the protective cover in his hand fell to the ground.

Chen Yan stepped forward to investigate carefully.

It turned out that there was a blood stains on this protective cover ...

"Master, come over and help."

Liu Qingshan immediately brought his gloves and opened the remaining protective cover with Chen Yan.

There are five sections of protective hoods in the entire stone transport belt.

Chen Yan and Liu Qingshan played the second and third sections. The remaining two sections were too high, and it was impossible to disassemble the bare hands.

"We have a ladder, the second priest, the second ladder came over in the past."

After a while, an electric lifting ladder was pushed under the conveyor belt.

Fifteen minutes later, the last two sections were also removed.

At the junction of the fourth and fifth quarter, a coat is hung on the damaged iron sheet protruding from the protective cover. There are many blood stains on each protective cover. After that, Chen Yan checked the crushing again.

There is no blood in it.

From this, it can be determined that the murderer is to open the protective cover on the transportation belt of the transportation stone, put the body into the conveyor belt, and then enter the cone -shaped stirring barrel.

"Arrange people and block the scene and conduct on -site surveys."

"yes!"

"Zhang Hui, please gathers all the personnel of the heads last night, we have to ask."

"Okay, you can rest assured, they are sleeping in the dormitory now, and I make everyone call it."

While this vacant, Chen Yan also started to investigate the scene.

In addition to blood stains, the coat found under the protective cover is obviously the most valuable clue.

This coat can be left, it is more coincidental.

The connection of the fourth and fifth section of the protective cover is damaged, and the sharp iron skin is stunned, just to scrape the clothes. But even so, the clothes are not complete, only about one -third of it looks like.

Chen Yan took his clothes and observed carefully.

This should be a light -colored top, with the residual right -handed sleeve jacket.

Um?

etc!

Pick up the clothes, Chen Yan's eyes flashed with a hint of joy. In the right pocket of the clothes, there is something!

"Take a certificate bag and the sister -in -law."

Chen Yan carefully clamped the things in the right pocket with a mule.

But it is not Chen Yangang's ID card, it is a white plastic card.

Pure white, there is a line of words in the upper left corner. Tianzhang Building.

Tianzhang Building? What is this?

An hour later, the on -site survey was basically over. Except for these blood and half -piece clothes and a white card, nothing was discovered.

There are no fingerprints on the protective cover, and there are no other special clues at the scene.

As for the surveillance video, Liu Qingshan has sent someone to view it.

The monitoring at the gate is a furnishings, which is indeed damaged.

The monitoring of the financial room is facing the staff, and the situation is not taken at all.

As for the people on duty last night, I also said that nothing was discovered.

Yesterday, the six -time night shift staff was sleepy at this moment.

"Nothing yesterday."

"The equipment on the station has been upgraded last year. Our main task is to add stone. Generally, add it once every two hours."

"I didn't pay attention to whether outsiders came in. At night, we were particularly busy. The mixing car that pulled the mortar coaxed, one by one for a while, no one came to see it."

"Never coming in outside the car, I don't know if I think of the door? The mixes in and out of the car yesterday, and the car of our boss, except for these cars, there were no other vehicles in."

The results of Liu Qingshan's interrogation are not very good.

There is no valuable clue.

No abnormalities were found on duty last night and those who took over a few days in the morning.

The workers who looked at the gate also certainly did not enter the strange vehicle last night.

Then, then

The brake reminds you in time: Remember to collect after reading
