Bai Song came with a team.
This morning I have Wang Huadong's class, and in the afternoon I have the forensic class of the Fourth Brigade. The forensic doctor has been transferred here, so the afternoon class is naturally suspended.
Not all the courses in this training are very important. In fact, the forensic course is a relatively unimportant course. It’s not that everyone can’t understand it, but the police don’t really use it because it’s too professional.
Police officers may rotate positions many times in their lifetime, but forensic doctors basically never rotate because it requires a medical background, which most people cannot do.
In the afternoon, most people were watching courseware at the training base. Bai Song, two forensic doctors from the Fourth Detachment, and a dozen outstanding students went to the Jibei Detachment.
"Captain Bai, do you think this is not a big deal?" On the minibus, a criminal police officer from the East District asked, "We in the Huang Detachment were convinced by you last time."
"Yes, yes," said the criminal police from the Second Brigade of Jiuhe District, "You don't know that when Team Bai went to Dashan Province, they once went to the bottom of a cliff and brought up a highly decomposed corpse."
"Cliff? How do we do that? Do we have any large machinery?"
"No, I just used a rope to get up there."
"That's really cruel... Captain Bai, please tell us about it..."
Although they were all police officers, they were all young people and still liked to listen to some strange stories, but Bai Song did not answer.
Because the scene we visited today was much more complicated than the one under the cliff last time.
It would have been fine if the tanker driver hadn't driven, but he drove for more than ten kilometers, and now, except for the warehouse facing the tank mouth, the other warehouses are in trouble.
First of all, these places have a large amount of toxic gases, whether it is hydrogen sulfide formed by decay or diesel vapor itself, it is possible that people will never return.
Secondly, can I bring oxygen cylinders?
I couldn't bring my oxygen tank with me, and I couldn't get into other cabins. People were allowed to crawl between cabins, but the oxygen tanks were too big.
The best way at the moment is to find some special equipment, such as small oxygen cylinders. Bai Song has already told the Jibei Branch.
Small oxygen cylinders can only last for a short time, but they are also useful. Bai Song will never allow Sun Jie and other forensic doctors to get off the tanks and enter other cabins without protection.
But even so, it is very troublesome, because it rained a little a few days ago, and the mouth of the can is small, so not much water can go in, but it has accelerated the spoilage process. Now the water inside is mainly soup, and multiple bags are needed to take it out little by little.
The car arrived at the scene quickly.
The basic argument has been made that the cause of death should be hydrocarbon poisoning.
This car is a diesel car and is mainly used to transport diesel.
Routine inspections have shown that diesel is indeed present.
Diesel is a type of hydrocarbon with relatively low volatility. C5~C12 aliphatic hydrocarbons and cycloalkanes are gasoline, while diesel is mainly C10~C22 macromolecular hydrocarbons. In fact, the boundary between these two types of oil is not very clear and is not so distinct.
For example, C11 cycloalkanes are found in gasoline and diesel.
Therefore, we cannot assume that diesel is non-toxic just because it has low volatility.
Judging from the current situation, the deceased should have external injuries. He should have slipped after entering the tank because there was a little oil left at the bottom. It is narrow inside and it is all steel plates. It is easy to die if you hit anything.
After arriving at the scene, there are now more than a dozen forensic doctors surrounding it.
"Team Leader Yue," Bai Song said after arriving at the scene. He saw the deputy leader of the Second Detachment of the Municipal Bureau, who was the leader of the Municipal Bureau. "You came all the way here in person."
"Even if it was an accident, the leaders took it very seriously because it was a sensitive term." Yue said, "But it is indeed troublesome. The best solution now is to bring in special oxygen tanks and fish it out bit by bit."
"What about integrity?" Bai Song asked.
"The main skeleton is intact, but the tissues are in a mess. This truck is shaking a lot, and there are pieces everywhere. We have to fix it bit by bit. It's a technical job." Yue said, "Send someone to the fire department to ask for some professional equipment. I heard that they have updated their equipment after this accident. There are a lot of new equipment, including oxygen equipment that can enter and exit narrow places."
"Where is the source of light?" Bai Song asked.
“With a headlamp.”
"Captain Yue, I have a suggestion. Don't use battery-powered lights. Just use LED cold light sources." Bai Song said, "Pull the sealed wires in, and use four bulbs to view the four compartments together."
"I'll go and ask about the feasibility." Captain Yue nodded.
…
While the forensic doctors were working intensively to find a solution to the problem, the police officers from the Jibei District Criminal Investigation Brigade also retrieved some basic information.
The deceased, a 17-year-old male, had a history of theft, but because he was under the age of 18, he was sentenced to probation and is now on probation.
The driver did not live nearby and had no connection with the deceased. In addition to the driver, the driver's family and company were also investigated.
I also checked the ones at the car wash, but there was no overlap.
After checking the deceased's interpersonal relationships, they were all 15- or 16-year-old hooligans. None of them admitted to having contact with the deceased during this period, and no one mentioned that the deceased was going to get oil. Some people even called the deceased a bastard, saying that he never kept his word and always liked to keep all the good things to himself.
The deceased's parents have similarities with the nurse parents Bai Song met, but they are much lower-level.
His father was a businessman, but he didn't have much money. His mother was a housewife who occasionally went out to do odd jobs and couldn't control her son.
If you put it that way, he is actually more like the husband of the woman who fell into the river.
The parents of the deceased came to the tanker truck driver to ask for money. They knew what kind of person their son was, but they insisted that parking the truck like that posed a safety hazard.
The truck driver started arguing with the deceased's father. The man's hoods were all closed, and the hood was even screwed shut. How could he blame the driver???
The father of the dead child was making a fuss there, and the mother was crying there, making a lot of noise.
Bai Song brought more than a dozen people and stayed here for an entire afternoon, accompanying the forensic doctor to clean out all the things.
Bai Song and Wang Liang are both fine, but three of the more than ten people they brought vomited.
Wang Liang would have had nothing to do after adjusting some surveillance footage, but he did not leave throughout the afternoon and kept an eye on the criminal police officers in training.
Seeing that three of the people brought by Bai Song vomited and two of the criminal police from Jibei Detachment vomited, Wang Liang was very satisfied.
This is because most of the people coming for training are not new police officers. Otherwise, if those newly recruited on September 28 were brought here, all the toilets here would be full.
When Li was murdered, which was the first murder case, Wang Liang went crazy by the river after eating at the buffet. He always felt embarrassed, but now he finally feels balanced...
After four years of holding it in, I finally feel relieved...
