Jibei District Criminal Investigation Detachment.

This case is supposed to be an accidental death, but the cause of death is very strange.

Due to the further investigation of all the special industries in the city, in the past two months, tankers have been inspected more than once, and many cars are afraid to run away, and they will be checked on the road.

After that period of time, this month, the cars that have gone through multiple security checks have resumed work one after another.

The tanker truck has been resting for half a month, and the driver has been leaving the car in an abandoned parking lot.

It's not so much a parking lot, it's actually an open space, because the place is big, there is no charge, and there is a traffic department monitoring nearby, so many bus drivers park here, and there are buses parked here every night.

The same is true for this tanker, which was empty and had less than 10 litres of fuel left before it stopped here.

Now there is really no way to park large cars, there are too many people who steal oil, and they leave too much for others.

The tanker driver was going to move today, and the car was so dirty, he first drove to refuel, then found a place to refill the water, and then washed the car nearby.

When the worker was washing, he asked the driver how the lid was opened, and the driver hurriedly climbed up to take a look, and found that the mouth of the can was indeed open, and there was a strong smell inside, and the driver immediately felt that something was wrong and immediately called the police.

When it comes to this, we have to talk about the structure of the big tanker.

The chassis and the front of the car are not mentioned for the time being, this big tank is not the hollow tank we think is not at all the hollow tank.

If the pure hollow tank is not fully loaded, every time it brakes and accelerates, it will cause excessive internal shocks and overload the vehicle.

Therefore, the current tank is divided into two warehouses and four chambers or multiple chambers with high-quality steel plates. There are connected pipes (for people to climb in and out) at the bottom of each compartment, so that the oil can be released from the only drain pipe at the back.

This design is very reasonable and allows the multi-layer steel plate to absorb the force of water.

In the anchor case, Wang Fufu died of the water hammer effect, and the power of the liquid cannot be underestimated.

Therefore, to further avoid this, each compartment may also have reinforced wave-proof partitions to increase stiffness.

The current standard for the mouth of the tank is 50 cm in diameter, and people who are not too obese can enter from here, and they can also enter through this place for maintenance on weekdays.

There is a large lid and a small lid here, the big cover is fixed on the mouth of the can by bolts, and the large and small covers are connected together by a branch and an ear plate, and the small cover can be covered by turning the small cover clockwise, pressing the small cover, and reversing it to open the small cover.

After listening to the introduction of the tanker truck driver, the police at the scene basically understood, in short, this big cover is opened, it requires special tools, and ordinary wrenches can be difficult.

The tanker truck was too tall and too big, and it was an empty tank, and the driver didn't notice that the lid was opened before driving, and there were some wrenches and pipes on the car that he didn't notice.

Large vehicles are not the same as small cars, and the engine and vehicle are too noisy while the car is moving. Sometimes, the trailer is rear-ended by a car, and it is not noticed.

The current situation, the preliminary judgment is that the 17-year-old boy wanted to steal oil, and after opening the tank, he found no oil, so he wanted to go in and have a look, but he died in it.

Judging by the traffic on the road, the teenager did come alone, he carried tools and pipes, but he did not carry oil storage equipment.

Assuming that this teenager has normal intelligence and wants to steal the oil from the tanker, he has brought all the pipes, why not bring the container?

Stealing a tanker truck directly, it is definitely not stealing a thirty-liter or fifty-liter one, logically speaking, you should also drive a car, what about the car?

However, there is only one traffic monitoring in this vicinity, and there are too many dead ends, and it is easy to avoid if you want to avoid it.

If the deceased drove alone and then died in the tanker, then the case is easy to solve because it is logical.

Now, there is a very incomprehensible situation, will there be an accomplice? If so, why didn't the accomplice save him? Was it an accident or did he kill him?

It was precisely because of the strangeness that Sun Jie and Wang Liang were called.

Wang Liang made a great contribution as soon as he came, he confirmed through traffic monitoring in many places that the deceased did not die there after putting the tools and pipes at the scene, and the next day he also appeared in the nearby hardware market and bought two large oil drums.

Through this video, it can be determined that there is nothing wrong with the death logic of the deceased, it may be that he went to see the scene on the first day, drove the next day or in some other way, such as riding a tricycle, avoiding the surveillance, and later died inside, but this parking lot is crowded and miscellaneous, so that the ownerless oil drums and tricycles and other means of transportation must have been taken by someone.

So the scene is the current state.

This logic is understandable, but Sun Jie and they have to work hard.

The body was so decomposed that it was impossible to identify it at all, and it was the first few days of death.

It's too complicated!

First of all, in the past half a month, the temperature difference is very large, and it has rained.

Every day, the temperature in the tank changes several times and is higher than the outside temperature.

The second is the environment inside the tank, because it is a multi-compartment and the vents are underneath, there is diesel fuel in each compartment, which will not volatilize cleanly in the short term.

No one knows what effect the high concentration of diesel gas has on the decomposition of the corpse and how long it lasts.

The corpse has exploded in the Giant Temple, and there is no way to take it out of this tank entirely.

Cut open the can?

People don't do it, this tank is still relatively new, and it is also special steel, but it is not cheap, who will pay for it?

Moreover, the decaying parts of the corpse are in the tanks of the four partitions!

In order to remove the corpse, it takes days of difficulty.

Not to mention anything else, just this smell and a large number of maggots, if it weren't for the police and forensic doctors, not many people would be willing to do tens of thousands of dollars.

After gas sampling of the tank, there is still residual diesel fuel.

The effect of this thing on the corpse under the fluctuating concentration is not found in the paper.

Of course, this also means that if the case is finally reported, a paper can be written.

At present, the case is determined to be an accident, but it is indeed the most troublesome and complicated scene encountered by the entire four detachments and Sun Jie and others!

Because the driver also drove for more than ten kilometers, and the inside itself was rotten, and then rubbed it back and forth...

Wandering around...

When Bai Song heard about this, he was speechless.

Let Bai Song say, just this can, who can go in and bring the corpse out by the way to make a scene investigation report, it is not much to give a second-class merit!

Because of this, a case that is not complicated quickly attracted the attention of the lecturers of the training center and the training of criminal police.

(Is this scene going to eat~)
