Police Detective

Jibei District Criminal Investigation Detachment.

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

Due to further large-scale inspections of all special industries in this city, vehicles such as oil tankers have been inspected more than once in the past two months. Many vehicles did not dare to run away and were inspected as soon as they hit the road.

After that period of time, this month, cars that have gone through multiple security inspections have gradually resumed work.

This tanker truck has been resting for half a month, and the driver has been parking it in an abandoned parking lot.

Rather than saying this is a parking lot, it is actually just an open space. Because the place is large, there is no charge, and there is a traffic department surveillance nearby, so many big truck drivers park their cars here, and buses park here every night.

The same is true for this oil tanker. Before it stopped here, the oil in the oil tank was all empty, and there was only less than 10 liters of oil left in the tank.

There is really no way to park large cars now. There are too many gas thieves, and if they leave too much gas, it is reserved for others.

The tanker driver had to drive the car today, and the car was really dirty. He first drove to refill the tank, then found a place to add water, and then washed the car nearby.

While the worker was flushing, he asked the driver why the lid was open. The driver quickly climbed up to take a look and found that the mouth of the can was indeed open and there was a strong smell inside. The driver immediately felt something was wrong and called the police.

At this point, we must talk about the structure of the large tank truck.

Leaving aside the chassis and front of the car, this big tank is not what we think of as a hollow tank at all.

If a pure hollow tank is not fully loaded, every time braking and acceleration occurs during running, the internal vibration will be too large and the load on the vehicle will be too high.

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

This design is very reasonable and allows multiple layers of steel plates to buffer the force of water.

In the anchor case, Wang Fanfan died from the water hammer effect. The power of liquid cannot be underestimated.

Therefore, to further avoid this situation, each cabin may also have reinforced wave partitions to increase rigidity.

The current standard for the mouth of the jar is 50 centimeters in diameter. Generally, people who are not too obese can enter through here. They can also enter through here for maintenance on weekdays.

There is a large cover and a small cover. The large cover is fixed on the mouth of the jar through bolts. The large and small covers are connected together by a support and an ear plate. Turn the small cover clockwise to cover the handle and press the small cover. Turn it over to open the small cover.

After listening to the tank truck driver's introduction, the police officers at the scene basically understood. In short, special tools are needed to open this large cover, and ordinary wrenches are very laborious.

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

Large vehicles are different from small cars. The engine and vehicle noise are too loud when the car is driving. Sometimes, a large trailer is rear-ended by a small car without even noticing it.

The initial judgment of the current situation is that the 17-year-old boy wanted to steal the oil. After opening the tank, he found no oil, so he wanted to go in and take a look, but he died inside.

Judging from the traffic video on the road, the boy did come alone. He brought tools and pipes, but no oil storage equipment.

Assuming that this young man has normal intelligence and wants to steal the oil in the tanker, he has brought the pipes, why not the container?

If you directly steal a fuel tanker, you are definitely not stealing a thirty-fifty-liter tanker. Logically speaking, you should also bring a car. Where is the car?

However, this is the only traffic monitoring area around here. There are too many blind spots, which are easy to avoid if you want to avoid them.

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

Now, there is a very incomprehensible situation. Is there an accomplice? If so, why didn't his accomplice save him? Was it an accident or homicide?

It was precisely because of something strange that Sun Jie and Wang Liang were called over.

Wang Liang made great achievements as soon as he arrived. Through traffic surveillance in many places, he confirmed that the deceased did not die there after placing the tools and pipes at the scene. He also showed up at a nearby hardware market the next day and bought two A big oil barrel.

Through this video, it can be determined that there is nothing wrong with the logic of the deceased's death. It may be that he went to see the scene on the first day and then drove the car the next day or some other way, such as riding a three-wheeler to avoid the surveillance. , and later died in it, but the parking lot was crowded and crowded, so the unowned oil drums and tricycles must have been taken advantage of by others.

So the scene is in its current state.

This logic is understandable, but Sun Jie and the others have given up their efforts.

The body was highly decomposed and it is impossible to confirm the day after death.

The environment here is too complicated!

First of all, in the past half month, there has been a huge temperature difference and it has rained.

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

Secondly, there is the environment inside the oil tank. Because it has multiple compartments and the vents are at the bottom, diesel oil is present in each compartment and will not evaporate cleanly in a short period of time.

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

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

Cut open the can?

The driver doesn't care. This tank is relatively new and made of special steel, but it's not cheap. Who will pay for it?

Moreover, the rotten parts of the corpse are in the four partitioned tanks!

In order to take out the corpse, it would take an incredible amount of effort.

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

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

The effects of this substance on corpses at varying concentrations cannot be found in any papers.

Of course, this also means that if a report is finally published on this case, a paper can be written.

The case is currently considered to be highly likely to be an accident, but it is indeed the most troublesome and complicated scene that the entire four detachments and Sun Jie and others have encountered!

Because the driver drove the car for more than ten kilometers, the inside itself was rotten, and he rubbed it again and again.

Wander around and around.

Bai Song was speechless when he heard about this.

Let Bai Song say, for this tank, whoever can go in and take out the body and make an on-site investigation report is not much more than a second-class merit!

Because of this, an uncomplicated case quickly attracted the attention of the lecturers at the training center and the training criminal police.

(Will food be served on site~)

What limits me is never lack of inspiration, but the size of the starting point...
