Chapter 1216: I Can Do It Too

Jiang Yuan checked the lower body of the body at the scene, took swabs from the vagina and rectum of the body, and then took the body back to the Forensic Center of the Beijing Bureau.

Although it has been more than a week since the incident, the body is relatively dry and has formed leather-like changes, which has a slowing effect on DNA degradation. If you are lucky, you might be able to retain a little bit of complete DNA. At that time, it will be amplified in the machine, and there is a probability that it can be done.

Or, if the perpetrator is a pervert and does something like raping the corpse, it might also leave traces.

Of course, it is a high probability that it cannot be done. The perpetrator is more likely to wear a condom or something. Outsiders understand these things, and forensic doctors naturally understand them, but what everyone is betting on is that you will make a mistake, and what cannot be accepted is that the perpetrator made a mistake and the police didn't seize the opportunity!

One hour later.

The body bag was placed on the autopsy table.

"Just cut the bag." Jiang Yuan had taken off the disposable protective clothing and shoe covers in the garbage dump, and changed into a new set this time. In short, the expenditure on personal protection today was hundreds.

Miao Ruixiang put on latex gloves, nitrile gloves, and cotton gloves in one breath, and then picked up the scissors for a fierce dry.

The body looked like a whole in the garbage dump, but when it was transported out, the rotten muscles and skin could not provide support. Whether it was the neck vertebrae like half a duck neck that had been gnawed, or the limbs that had long been bitten off, or the abdomen that had rotted into stir-fried liver, they were all fighting on their own, and finally could only be packed in several bags and brought back.

"Liver, stomach, pancreas, etc. are gone, and the rest is mostly intestines." Miao Ruixiang carefully poured the internal organs into the bucket first.

Xiao Si helped all the way, and his whole body was dirty. At this time, looking at Miao Ruixiang who was trying hard to comb the remaining incomplete intestines, he couldn't help laughing: "Pan intestine battle."

"Go help." Cui Qishan followed Xiao Si, knowing he would have a cheap mouth, didn't expect him to start at zero frames.

Xiao Si "he" a sound, and went up to help Miao Ruixiang comb the intestines.

Jiang Yuan moved a position and began to prioritize the chest cavity.

The position where the deceased was stabbed had rotted into a concave, but because of the decay around it, some slight traces could still be seen.

Jiang Yuan touched it gently with his hand for a while, and found the broken mouth cut by the blade on the ribs. The evidence validity here is more able to prove the knife wound than the opening in the muscle part of the rotten part.

Jiang Yuan turned sideways and simulated the route of the knife, then said: "This is directly stabbed into the heart. The accuracy is okay, but the technique shouldn't be very skilled."

"Because it stabbed the ribs?" Liu Jinghui stood a few steps away, watching with a mask.

Jiang Yuan "hmm" a sound, and said: "It hit the blade, it's still a bit dangerous. If it's professional, it won't be stabbed like this. But judging from the amateur level, it's not bad, at least it's a knife used."

Liu Jinghui "hmm" a sound and pondered.

Wei Shiyan was a bit curious and said: "How do professionals stab?"

"Oh, you can stab parallel to the ribs, so the probability of touching is relatively low." Jiang Yuan gestured and explained, then said: "Amateur people naturally hold the knife. Whether it is stabbing the chest face-to-face, or from behind, they are usually used to holding the blade vertically. The killer also did this, but it was scratched in. It can be seen from the state of the rib break."

"So that's it... If it's parallel stabbing, if it's a positive hand knife, it's not easy to exert force. This is also the advantage of the reverse hand knife." Wei Shiyan said and doubted: "Professionals can't all be positive hand knives."

"No need to exert force." Jiang Yuan's voice was muffled, and said: "The victim is likely to be under control. At this time, if you are not sure, you can directly touch the position of the ribs with your hand, and then slowly hand the knife, which can ensure that you don't stab the ribs. If the technology is a little better, you can also ensure that there is no large bleeding."

"Did the victim have large bleeding?" Liu Jinghui was still very concerned about this question.

"Not sure. Judging from the position of the injury, if the heart is stabbed, causing pericardial tamponade or ventricular fibrillation, or aortic rupture leading to rapid shock, it is possible to die, and there will be no large bleeding." Jiang Yuan didn't describe the various possibilities of large bleeding. Large bleeding itself died, and it was impossible to prove it at this time.

The trouble with the rotten body is here, but it has been able to provide a considerable amount of information.

Jiang Yuan started from the head and dissected all the way, and extracted as many biological samples as possible.

"Brain tissue decay liquefaction, skull no fracture."

"Neck deep layer, hyoid bone complete, muscle no bleeding."

"Lung tissue decay, dark red."

Jiang Yuan had already turned on the "temporary +1" for the crime scene, and at this time, forensic pathology didn't need to be turned on. However, for the body in front of him, LV4 or LV5 was more than enough, and it didn't need to be used at all.

The autopsy went very quickly, and there were not many controversial places. Jiang Yuan also spent more time in the chest, in order to give a relatively accurate shape of the murder weapon: single-edged, more than 12 cm.

With this conclusion, as a forensic doctor, it can be said that he perfectly fulfilled his duties.

But as the person in charge of the task force, Jiang Yuan's work had just begun.

"Is the garbage pulled back?" Jiang Yuan left the remaining work to Miao Ruixiang and came to the autopsy table next to him.

"The garbage around the body has been pulled back." Cui Qishan responded and said: "It's you. Under normal circumstances, the Forensic Center cannot let so much garbage be sent in."

"It's all the same smelly." Jiang Yuan didn't take off his mask, just slowly changed a pair of gloves.

"What are you looking for?" Cui Qishan was a little expectant.

"Don't know." Jiang Yuan answered very realistically and said: "What is the difference between things thrown into the garbage dump by the killer and things thrown into the garbage dump by residents?"

"Uh... this..." Cui Qishan was a little stumped, and couldn't help but say: "The victim has been dead for more than a week, I don't know how long it has been abandoned. If there are things thrown together, wind blowing and sun drying, insect biting and rat biting, it is indeed very difficult to distinguish."

Jiang Yuan nodded, and on the autopsy table, he pulled a bag of garbage that had just been poured out.

In front of him, there are various vegetable leaves, fruit peels, bones, various papers, mineral water bottles, broken glass and canned boxes, as well as shredded wool and plush toys. In addition, you can see batteries and expired medicines, bricks and broken wood...

Jiang Yuan turned over while dividing the garbage into different types.

LV4 garbage classification, silently used it.

Cui Qishan tilted his head to watch, and at first thought Jiang Yuan was placing different garbage at will, but soon found that it was different.

"Your classification, what rule is it based on?" Cui Qishan watched for a while and asked.

"It is based on the integrity of the items." Jiang Yuan's answer, Cui Qishan could think of a part, but it was uncertain.

Xiao Si "hissed" a sound: "Oh, right. Most of the things thrown away by residents are unwanted, belonging to waste. But the killer and the victim, the reason they throw things away is not because they are broken or damaged or unwanted. Therefore, among the items found near the body, those that are relatively complete and still usable are most likely discarded by the killer."

"That's what it means." Jiang Yuan nodded.

Cui Qishan slapped Xiao Si with a slap: "It shows you!"

Jiang Yuan turned his head and said: "I didn't understand clearly just now. The garbage taken was all near the body. I just turned it over, and there were too few complete items. I see that the garbage dump is not big, so based on this principle, turn the garbage dump over."

"Uh... alright." Cui Qishan naturally couldn't refuse, turned his head and said: "Xiao Si, you go to the front."

"Shen Yaowei is still in the garbage dump, I will let him connect with you." Jiang Yuan turned his head and told Wang Chuanxing again.

At this time, Wei Shiyan couldn't help but say: "Master, you always like to point Shen Yaowei to do things recently. This kind of thing, I can do it too!"
