Chapter 674: Dissecting the Corpse

"The corpse was burned, and the skin is mostly carbonized..."

"The face below the level of the lower eyelid to the mandibular margin area is severely collapsed and deformed..."

"No obvious trauma was seen on the neck, trunk, or limbs, and there were no defensive wounds on the hands."

While Jiang Yuan was speaking, he finished the corpse surface examination.

For a player with LV1 forensic pathology, doing a corpse surface examination still requires very serious repeated confirmation.

Especially the location of the photo. If you write the wrong thing, it is embarrassing and easy to affect later work.

But for someone like Jiang Yuan who started with LV3 forensic pathology, he had never encountered a bottleneck in physical examination.

Wu Wu Fa Yi Gong, who was cooperating on the side, also nodded slightly, thinking: Looking at the corpse surface examination alone, Jiang Yuan's technique is indeed okay, dripping water without leaking from top to bottom, basically unable to find any shortcomings. Today is not a wasted wait...

"Then let's start the autopsy, give me the scalpel... need to loosen it here..." Jiang Yuan reached out for the scalpel while speaking and started to draw on the corpse.

The difficulty of dissecting a corpse after being burned is much greater than that of an ordinary corpse.

It is not just that the difficulty of work such as cause of death judgment has increased, but the dissection itself has become somewhat difficult. Because the burned corpse is dehydrated, the muscles are contracted, and the corpse will become quite hard.

For normal dissection, the most commonly used are scalpels and scissors. Bone saws, bone chisels, etc., are used and put down.

But when encountering a corpse after burning, the latter heavy weapon becomes a conventional weapon. Some forensic doctors with relatively small strength may directly use electric bone saws or craniotomy saws.

Wu Wu Fa Yi Gong also had experience. Seeing Jiang Yuan start the dissection, he started to help find the electric bone saw.

He lowered his head to flip through the tools, changed the blade for the bone saw, and when he raised his head, he saw Jiang Yuan had already laid the corpse flat.

The corpse was originally in a curled state and could not be laid flat completely. At this moment, it was already completely lying flat.

Wu Wu Fa Yi Gong couldn't help but "Eh," a little unsure of how Jiang Yuan did it, and why he did it so quickly.

Jiang Yuan naturally had no time to pay attention to Wu Wu Fa Yi Gong's psychology. He opened the trachea and esophagus all the way, first sampled the black mucus found inside and sent it for inspection, and then opened the chest rhythmically, exposing the lungs.

The lungs, which seemed to be undamaged externally, were now rotten into a piece, with blood spots between the lung lobes, and visible pulmonary bullae on the edges of both lungs. Touching the lungs with hands also had a crepitus feeling.

"What is this situation?" Qi Changye was not here to help, so he asked first when he saw the abnormal situation.

"It should be that after the explosive exploded in the mouth, the energy was transmitted downward, causing the lung lobes to expand rapidly. If you open the cranial cavity later, you should also be able to see the contusion of the brain tissue..." Jiang Yuan explained casually and continued to dissect downward.

Wu Wu Fa Yi Gong nodded while working. Jiang Yuan's explanation was very clear. He understood it as soon as he heard it and agreed with it, but it was not so easy to really collect evidence. Loosening, taking photos, collecting evidence, etc., all had to be done step by step.

Also because the corpse had been burned, the interior was also twisted and deformed, so conventional dissection knowledge was not enough. And if it was forced, not only would the difficulty increase, but it would also be more laborious and time-consuming. It can be said to be the reverse operation of Pao Ding dissecting a cow.

Wu Wu Fa Yi Gong's twisting did not affect Jiang Yuan's work.

Jiang Yuan, who was topped with LV5 forensic pathology, basically could not have problems in the basic link of corpse dissection. He did it all the way, didn't use much brain, and all were mature and classic solutions.

At the same time, Jiang Yuan used more energy to analyze phenomena and problems.

Especially the residues of explosives in the lungs, trachea, esophagus, and oral cavity, Jiang Yuan found them as much as possible.

Some residues were exposed, but most of the explosive fragments were actually embedded in the tissue. And because there were many injuries in the oral cavity and trachea, it was almost impossible to accurately find the explosive fragments through the rupture points. This work would have taken a lot of time.

However, Jiang Yuan just gestured, and after letting Wu Wu Fa Yi Gong take more photos, he almost dug out a fragment with two knives.

Wu Wu Fa Yi Gong frowned. Why was this again?

Seeing Jiang Yuan dig out more than a dozen fragments in a while, Wu Wu Fa Yi Gong finally couldn't help but ask: "Brother Jiang, how do you know where there are explosive residues?"

"I actually played a rogue..." Jiang Yuan smiled and said while doing it: "Generally speaking, we find explosive fragments first, and then judge the explosive. But because there are actually a few explosive residues exposed in the oral cavity, I will judge what it is and how powerful it is first, and then I can judge which wounds are caused by shock waves, which are energy burns, and which are injuries from fragment injection..."

"Ah?" Wu Wu Fa Yi Gong widened his eyes, and seven or eight questions instantly arose in his mind.

Before he could ask again, Qi Changye on the side was already concerned: "What do you think the explosive is?"

"Batteries, I guess. Specifically, a physical and chemical inspection is needed. If the components of the battery can be detected in this viscous substance, there should be no problem." Jiang Yuan, topped with LV5, easily made an inference.

Qi Changye was surprised: "Suicide with a battery? Is it possible that only the battery exploded, and the real explosive did not explode."

"It cannot be determined as suicide." Jiang Yuan turned his head and looked at Qi Changye and said: "The existing evidence does not support the conclusion of suicide."

"Didn't you say that no wounds were found on the limbs, and there were no defensive wounds on the hands? If it's not suicide, who can put the explosive into his mouth?" Qi Changye paused and added: "I forgot to tell you just now, this person is the suspect who made the Z-shaped tool and pried open the rolling shutter door. He has a record of violent crime and doesn't look like someone who would be captured without a fight."

Jiang Yuan was stunned, then shook his head slowly and said: "No other explosives were found. Just saying that batteries are used for suicide, detonation is also a problem. Although the victim has the ability to make tools by himself... using detonators or even double-kickers is more convenient and reliable than using batteries."

"Seems to make sense..." Qi Changye was a little hesitant.

"The way of putting explosives into the mouth to commit suicide is still relatively rare. If the victim is familiar with tools, there are more choices. Therefore, I think it cannot be determined as suicide for the time being."

Qi Changye nodded slightly: "No defensive wounds, not suicide, it can't be an accident, that's too coincidental... Remote control?"

Jiang Yuan blinked: "Not excluded."

"Can it be proven? He can't just put a battery in his mouth and explode. There must be a shell or something."

"Didn't you find any clues at the scene?"

Qi Changye shook his head: "The area of the fire at the scene is still relatively large."

"Then I'll look for it again." Jiang Yuan said and buried his head in work.

The fragments left in the victim's oral cavity were all very small. Finding them out one by one was indeed quite difficult.

In addition, Jiang Yuan didn't want to completely destroy the deceased's oral cavity, so as not to need subsequent examinations.

Wu Wu Fa Yi Gong followed Jiang Yuan to do it, and soon became powerless. For him, this was a multiple consumption of brain power, physical strength, and self-confidence. The more difficult it was, the harder it was to persist.

At this time, Jiang Yuan managed to find dozens of fragments, then used tweezers to piece them together slightly, making a few small piles that couldn't see the shape.

Just when others thought the attempt failed, Jiang Yuan threw the tweezers and exhaled: "It might be an e-cigarette."

"Ah?" Qi Changye immediately became energetic: "He is a smoker of e-cigarettes!"

Jiang Yuan nodded: "The battery in the e-cigarette exploded, and part of it splashed on the face. Most of the fragments are estimated to have fallen to the ground and should have been burned by the fire."

Qi Changye frowned and concentrated: "So, arson is not necessarily to burn the corpse to destroy the evidence, but more likely to cover up the means of murder? But how did they know when the victim was smoking an e-cigarette? What did they use to observe?"

Saying is saying, he didn't expect Jiang Yuan to answer all the questions, but was stimulated by the questions he raised and became excited. ===== CHAPTER 675 =====
