Jibei District Criminal Investigation Detachment.
This case should be an accidental death, but the cause of death is very strange.
Due to the further inspection of all special industries in the city, vehicles such as tanker trucks have been inspected more than once in the past two months. Many vehicles dare not run anymore and are inspected as soon as they go on the road.
After that period of time, this month, the vehicles that had passed multiple safety checks have gradually resumed work.
This tanker truck has been resting for half a month, and the driver has left the vehicle in an abandoned parking lot.
Rather than calling it a parking lot, it is actually just an open space. Many truck drivers park their cars here due to the large space, free of charge, and a traffic surveillance camera nearby. There are also buses parked here every night.
The same is true for this tanker truck. Before it stopped here, the oil in the tank was completely empty, and there was less than 10 liters of oil left in the tank.
There is really no way to park large vehicles nowadays. There are too many people stealing oil, and any extra space left is left for others.
The tanker driver was going to move his car today, and his car was so dirty that he first drove to fill it with gas, 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 tank was indeed open and there was a strong smell inside. The driver immediately felt something was wrong and called the police.
Speaking of this, we must talk about the structure of the tank truck.
Not to mention the chassis and the front of the car, this big tank is not the hollow tank we think it is.
If a purely hollow tank is not fully loaded, each braking and acceleration during running will cause excessive internal vibrations, which will put too much load on the vehicle.
Therefore, the current tank body is made of high-quality steel plates to divide the entire tank body into two compartments and four chambers or multiple compartments and multiple chambers. There is a connecting pipe under each compartment (for people to climb in and out), which allows the oil to be released 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 ** cannot be underestimated.
Therefore, in order to further avoid this situation, there may be reinforced wave-breaking bulkheads in each cabin to increase rigidity.
The current standard for the tank mouth is 50 cm in diameter, so anyone who is not too obese can enter through here. It can also be used for daily maintenance.
There is a big cover and a small cover here. The big cover is fixed on the mouth of the jar with bolts. The big and small covers are connected together by a support and an ear plate. Turning the small cover clockwise can cover the handle and press the small cover, and reversing it can open the small cover.
After listening to the tanker driver's introduction, the police at the scene basically understood what he said. In short, special tools are needed to open the big cover, and ordinary wrenches are difficult to use.
The tanker truck was too tall and too big, and it was an empty tank. The driver did not notice that the lid was open before driving away, and he also did not notice some wrenches and pipes in the car.
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, but no one notices it.
Based on the current situation, the preliminary judgment is that the 17-year-old boy wanted to steal oil. After opening the tank, he did not find any oil, so he wanted to go in to check, and ended up dying in there.
Judging from the traffic video on the road, the teenager did come alone. He carried tools and pipes, but no oil storage equipment.
Assuming that this teenager had normal intelligence and wanted to steal oil from the tanker truck, he brought the pipes, so why didn't he bring the container?
If you steal the oil tanker directly, you definitely won't steal just 30 or 50 liters of oil. Logically, you should also drive a car. Where is the car?
However, there is only one traffic surveillance camera in this area, and there are too many blind spots, so it is easy to avoid them if you want.
If the deceased drove here alone and died in the tanker truck, then the case would be easy to solve because it makes sense.
Now, there is a very incomprehensible situation. Could there be an accomplice? If so, why didn't the accomplice save him? Was it an accident or murder?
It was precisely because of the strangeness that Sun Jie and Wang Liang were called over.
Wang Liang made great contributions as soon as he arrived. Through traffic surveillance in multiple places, he confirmed that the deceased did not die after placing the tools and pipes at the scene. He appeared in a nearby hardware market the next day and bought two large oil drums.
Through this video, we can determine that there is nothing wrong with the logic of the deceased's death. He may have gone to see the scene on the first day, and drove there on the second day or used other means, such as riding a tricycle, to avoid surveillance, and then died in it. However, this parking lot is crowded and mixed, so the ownerless oil drums and tricycles and other means of transportation must have been stolen by someone.
So this is the current state of the scene.
This logic is understandable, but Sun Jie and his team were at a loss.
The body has been highly decomposed and it is still impossible to confirm how many days have passed since death.
The environment here is too complicated!
First of all, there has been a big temperature difference in the past half month, and it has rained.
Every day, the temperature in the oil tank changes several times and is higher than the temperature outside.
The second is the environment inside the oil tank. Because there are multiple compartments and the vents are at the bottom, there is diesel in every compartment and it will not evaporate completely in a short period of time.
No one knows what effect the high concentration of diesel gas in here has on the decomposition of the corpse and how long it lasts.
The corpse had already exploded, and there was no way to get it out of the tank in its entirety.
Cut open the tank?
The driver refused to do that. The tank was relatively new and made of special steel, but it was not cheap. Who would pay for it?
Moreover, the rotten parts of the corpse are in the four partitioned tanks!
It would take a lifetime of effort to retrieve the body.
Not to mention anything else, just the smell and the large number of maggots, if they were not the police or forensic doctors, not many people would be willing to do it for tens of thousands of dollars.
After taking gas samples from the tank, it was found that there was still diesel residue.
I can't find any papers on the effects of this stuff on corpses at varying concentrations.
Of course, this also means that if a report is finally produced on this case, a paper can be written.
The case is currently determined to be more likely an accident, but it is indeed the most troublesome and complicated change scene that the entire Fourth Detachment and Sun Jie and others have ever encountered!
Because the driver drove the car for more than ten kilometers, the inside was already rotten, and he kneaded it again and again...
Wandering around...
When Bai Song heard about this, he was speechless.
Let Bai Song say, with regard to this jar, whoever can get in, take the body out and make a scene investigation report, will be given at least a second-class merit!
It is precisely because of this that a simple case quickly attracted the attention of lecturers and criminal police trainees at the training center.
