White Pine came with a team.

This morning is Wang Huadong's class, and in the afternoon is the forensic doctor of the four detachments, and the forensic doctor has already been transferred, so the afternoon class will naturally stop.

Not all of the courses in this training are very important, and the forensic course is actually a less important course. It's not that you can't understand it, it's mainly that the police themselves don't need it, because it's too professional.

A police officer may rotate many positions in his life, but the position of forensic doctor is basically not rotated, because it requires a medical foundation, and ordinary people can't do it.

In the afternoon, most of the people were watching the courseware at the training base, and Bai Song, two forensic doctors from the four detachments, and more than a dozen outstanding trainees arrived at the Jibei detachment.

"White team, is this kind of thing not a big deal in your opinion?" On the bus, the criminal policeman of the Tiandong District asked, "Our Huang Detachment served you last time." ”

"Yes, yes," said the criminal policeman of the Second Brigade of Jiuhe District: "You don't know, the white team went to Dashan Province back then, and once went to the bottom of a cliff to get a high-rotting corpse. ”

"Cliffs? What's that going on? Are there any big machines?"

"Why, I got it up with a rope. ”

"That's really ruthless... Captain White tell us about it..."

Although they are all policemen, they are all young people, and they still like to listen to some strange stories, but Bai Song did not answer.

Because the scene I went to today was much more complicated than the last time I went under the cliff.

The tanker driver is good if he doesn't drive, the driver has driven more than ten kilometers, and now except for the warehouse opposite the tank mouth, the others are very troublesome.

First of all, there are a large number of toxic gases in these places, whether it is hydrogen sulfide formed by decay or diesel vapor itself, which can be left and never returned.

Secondly, Can I bring an oxygen cylinder?

I can't bring it, I can't get into other cabins with an oxygen cylinder. People are allowed to crawl around between each compartment, but the oxygen tanks are too large.

At present, the best way is to find some special equipment, small oxygen cylinders, Bai Song has already told the Jibei Branch.

The small oxygen cylinder lasts for a short time, but it is also useful, and Bai Song will never allow Sun Jie and other forensic doctors to get off the tank and enter other cabins without protection.

But even this is very troublesome, because there was a light rain a few days ago, the mouth of the can is small, and there is not much water in it, but it also accelerates the process of decay, and now it is mainly soup, and it needs to be taken out little by little in multiple bags.

The car was soon on the scene.

The basic argument has come out that the cause of death should be hydrocarbon poisoning.

The car is a diesel car, mainly pulling diesel.

At present, through routine inspection, there is indeed diesel in it.

Diesel is a class of hydrocarbons with weak volatility, C5~C12 aliphatic hydrocarbons and naphthenic hydrocarbons are gasoline, and diesel is mainly C10~C22 macromolecular hydrocarbons.

For example, C11 naphthenes are found in gasoline and diesel.

Therefore, it cannot be felt that diesel is not volatile, so it is not toxic.

Judging from the current situation, the deceased should have had external injuries, and it should have slipped after entering the tank, because there was a little oil left at the bottom. It's cramped, and it's full of steel plates, so it's easy to finish off anywhere.

After arriving at the scene, there are now more than a dozen forensic doctors around.

"Yue Detachment", after Bai Song arrived at the scene, he saw the deputy head of the second detachment of the Municipal Bureau, who was the leader of the Municipal Bureau: "You have come in person for such a long journey." ”

"Even if it is an accident, the sensitive word tanker truck is touched, and the leader attaches great importance to it. Yue detachment said: "But it's really troublesome, and the best plan now is to bring a special oxygen tank in and fish out little by little." ”

"What about integrity?" Bai Song asked.

"The main skeleton is complete, as for the organization, it's messed up, this big car is shaking, there is everything, let's get it little by little, it's a technical job. Yue detachment said: "Find someone to go to the fire department to ask for professional equipment, I heard that after this accident, their equipment has also been updated, there are a lot of new equipment, and there are oxygen equipment that can enter and exit narrow places." ”

"Where's the lamp source?" Bai Song asked.

"There are headlights. ”

"Detachment Yue, I have a suggestion, don't use the battery light source, just pull the LED cold light source. Bai Song said: "Pull the airtight wire in, and the four light bulbs will look at the four cabins together." ”

"I'm going to ask about feasibility. Detachment Yue nodded.

...

While the forensic doctors were working intensively to find a way to solve the problem, the police of the Jibei District Criminal Investigation Detachment also transferred some basic situations.

The deceased, male, 17 years old, had a history of theft, but was sentenced to probation because he was under 18 years of age and is now on probation.

The driver did not live in the vicinity and had no contact with the deceased, in addition to the driver, the driver's family and the company also checked.

The car wash shop also checked, and there was no intersection.

After checking the deceased's interpersonal relationships, they were all fifteen or sixteen-year-old gangsters, none of whom admitted to having contact with the deceased during this time, and no one mentioned that the deceased was going to get oil or anything like that. However, some people also scolded the deceased as a bastard, saying that he never paid attention to righteousness, and always liked to eat alone when he encountered good things.

The parents of the deceased have similarities with the parents of the nurse that Bai Song met, but they are much lower.

The father is a businessman, but he doesn't have much money, and the mother is a housewife who occasionally goes out to work as a casual worker, and can't control her son.

To put it this way, it is actually more like the husband of a woman who fell into the river.

The parents of the deceased came to the tanker driver to ask for money, they knew what kind of beating sex their son had, but they insisted that the big truck parked there like that, and there was a safety hazard.

The driver of the big truck scolded the father of the deceased, and the big and small covers were closed, and the big covers were screwed on with bolts, so the driver could be blamed???

The father of the dead child made a fuss there, and the mother cried there, and the trouble was very fierce.

Bai Song took more than a dozen people and stayed here for an afternoon, accompanying the forensic doctor to clean up everything.

Bai Song and Wang Liang were fine, and three of the more than ten people they brought vomited.

Wang Liang had nothing to do after adjusting some surveillance, but he didn't leave in the afternoon, just staring at these trained criminal policemen.

Seeing that the people brought by Bai Song vomited three, and the criminal police of the Jibei detachment vomited two, Wang Liang was very satisfied.

This is also because most of the new police officers who come to the training are not new police officers, otherwise, if the new recruits on September 28 are brought in, the toilets here will be full.

Back then, Li's murder case, which was the first murder case, Wang Liang went crazy by the river after eating the buffet, he always felt embarrassed, and now it is finally balanced...

It's been held back for four years, and once it's happy...
