Chapter 948 Garbage Classification

Chapter 948 Garbage Classification

There are no secrets in the slum area, let alone among the oppressed mushroom people.

It took Meng Chengbiao just a quarter of an hour to get the result of the interrogation. He came over to report, "There are three bodies known to be found. One was beaten to death, and two were beaten to death. The smell you smell suggests that they died three days ago. No one cared at the time, so they were dumped next to the garbage dump. Only when we arrived today did the gang members have someone dig a pit and bury them."

"Then let's dig it out and take a look." Jiang Yuan sighed. His hands were fragrant now, just right for dinner, so he was somewhat reluctant to touch the corpse.

"We've already sent people to dig up the other two bodies, who died about two months and four months ago. We've also dug a hole and buried them there. We don't know if there were any bodies from an earlier time. We have to ask the core members of the gang if we can find any."

"Well, no rush, take your time. I'll take a look at the scene first, and then think of an investigation plan. Except for the necessary personnel who stay behind, everyone else should retreat outside the village." Jiang Yuan's thinking is purely that of a technician. In theory, this village is full of evidence, so naturally he wants to minimize the damage.

After all, three people died, one of whom was clearly murdered. In a local situation, sweeping a residential area that is several hundred meters wide is not a big project.

However, the complexity of the slum area, or in other words, its information density is much greater than that of the residential area. Moreover, these people have lived in Qishanzhai for several months or even more than a year. As their natures are released, they have committed many crimes against each other. Jiang Yuan thought that they could not be simply covered by one or two charges. It is better to adopt an open mind and tolerate all mushroom people.

It is clear that crimes committed among mushroom people are also crimes.

"Do we have signboards with different colors?" Jiang Yuan walked around the village and turned to ask Wang Chuanxing.

"They only brought yellow markers, so they shouldn't have brought much." Wang Chuanxing quickly checked on his PAD. They came with a lot of equipment, but the survey equipment was obviously second-level within the scope of the early delivery.

Jiang Yuan thought for a moment and said, "Then use a cordon. Circle the location I pointed out and make it the focus of investigation later."

Jiang Yuan actually had no aversion to this chaotic, dirty, strange-smelling village. He even enjoyed a sense of challenge.

Nowadays, most murder investigations are conducted indoors. Because there are many surveillance cameras and cameras outside, ordinary murderers feel more at ease killing people indoors, and dismembering the body is also easier to deal with.

If we look at it from the perspective of an ordinary person dying in his or her own home, the area that the on-site investigators need to survey is only about 100 square meters. In a small town or county town, the area may be a little larger, while ordinary people in big cities may only have an area of ​​30 to 50 square meters or 180 square meters. In terms of area alone, the difficulty of the survey is incomparable to that of Qishanzhai.

Furthermore, there are hundreds of people in this mountain-riding stronghold, who eat, drink, defecate, urinate and sleep there all year round, and also engage in various legal and illegal activities. If we want to sort out as many crimes as possible, the difficulty of the investigation will be quite high.

But Jiang Yuan was indeed quite confident. Not only did he have Level 4 crime scene investigation, but he also had Level 4 garbage sorting in the case of the old man who collected rubbish.

It's really suitable for this garbage scene.

Jiang Yuan carefully marked each location, preparing to go back and conduct a detailed survey.

For criminal police, digging out evidence from garbage dumps can be said to be a basic operation.

For example, in the Qishan Village, the first thing that can be dug out is various drug paraphernalia, because although the people in the village like mushrooms, many people are not the only ones who like mushrooms. Therefore, you can find various needles, aluminum foil, tinfoil, hookahs, pipes, large and small plastic bags, pots, bottles, etc. in the garbage.

It is conceivable that these items have not been thoroughly cleaned, disinfected, or had their traces removed. So, what can you get if you get a plastic bag that has nothing special?

First, a physical and chemical analysis of the bag can reveal what was in the bag, in this case, what drugs were in the bag.

Secondly, the fingerprints on the bag can be easily obtained, and through the fingerprints, they can be matched with all the mushroom people who have taken the bag.

Assuming that there are fingerprints of five mushroom people on the bag, then we can do urine or hair tests on the five mushroom people, or directly arrange for them to be tested in a toxicology laboratory, and we can know what kind of drugs they took. If the type of drugs is consistent with the type of drugs in the bag, then we can assume that the bag was used by this person. As for the rest, they are naturally suspected traffickers, otherwise, why are your fingerprints on the bag?

At this point, the burden of proof is reversed, and the other person has to prove how they came into contact with the bag and left fingerprints. Gathering to take drugs is an explanation with relatively small losses.

As for other explanations, such as explaining that he used it as currency - the current law does not recognize such a transaction method, or in other words, using drugs as currency is drug trafficking, and each use is considered drug trafficking. It is natural to be sentenced to 7 years in prison for using drugs to buy a bottle of water.

If a bag could still wrongly accuse a person, then more objects of evidence could easily pinpoint a person as being involved in a drug trafficking incident, such as syringes, tinfoil, cooking pots, and other items. If you don't use or sell drugs, how could your fingerprints be on them?

Of course, the actual investigation is not that complicated. If the suspect is willing to plead guilty during the interrogation, there is no need to conduct such detailed inspection and disassembly. For low-level drug traffickers who plead guilty and accept a sentence of more than 10 years, prosecutors are generally satisfied.

As for other charges, especially those resulting from people reporting on each other and making meritorious contributions to each other, they can be added up later.

However, these are very detailed tasks, and Jiang Yuan cannot complete them in one or two days. Jiang Yuan walked around, identified the key areas, and waited for more technicians to come and help.

At this time, the three bodies were also dug out.

The two old corpses were already badly decayed, but since they had only been dead for three days, their condition was still acceptable even if they were buried in a relatively humid place.

Wang Chuanxing asked: "Do we need to do an external examination of the body? Or should we just ship it back?"

"Let's send the other two back for disposal. I'll do an on-site autopsy on this fresher body." Jiang Yuan said as he asked someone to bring over the forensic investigation box.

There was no need to find any special place. In a large yard without walls and roof, Jiang Yuan straightened the body and began the autopsy with the help of Mu Zhiyang and Shen Yaowei.

Making a straight incision and removing the internal organs are all very normal procedures.

In the past, forensic doctors often performed autopsies in the wild. In fact, the forensic doctors in Ningtai County were still performing autopsies in rural courtyards more than a decade ago. Because it was troublesome to bring the specimens back, it was better to have criminal police help on the scene so that they could give forensic opinions on the spot.

When Jiang Yuan graduated, the working environment of forensic scientists had already been reformed, but this time he felt like he was going back in time.

Especially when all the internal organs were processed and the skull was opened, and I found that I didn’t bring the electric saw, the sense of déjà vu of the old times became even stronger.

"Use a hand saw." Jiang Yuan couldn't wait a few hours for the electric saw to be delivered, so he asked someone to get a hand saw and handed it to Shen Yaowei.

Shen Yaowei took the hand saw solemnly and said seriously: "Captain Jiang, you take a rest first. I will call you when I am done sawing."

It takes about an hour to open the skull with a hand saw, so Shen Yaowei rolled up his sleeves and got to work.

Crunchy...

When the blade of a hand saw broke, he replaced it with another one. Shen Yaowei was sweating profusely while working and refused the kind offers of help from other criminal police officers.

This was a task that Captain Jiang had specifically ordered, so Shen Yaowei naturally refused to delegate it to anyone else!
