Chapter 799

The body had already been autopsied. A long surgical suture line ran through the chest and abdomen, as if the person had been split in two and then sewn back together.

On the head, a white towel was wrapped around it because the head had truly been split in two, and now it was bundled up with the towel.

Jiang Yuan looked at the autopsy record and decided not to perform a third autopsy.

Jacob had just performed a second autopsy and found nothing, which is why he called Jiang Yuan. As for a third autopsy, there was nothing left to dissect.

As it stands, the deceased's three cavities had already been emptied; the heart, liver, spleen, stomach, kidneys, brain, etc., had long been removed, and whatever needed to be sliced had been sliced. Cutting it open again would be meaningless; all that could be seen were bones and flesh.

And for important organs like the brain, the handling by Jacob and the others was extremely standard: first pickled in paraffin, then carefully cut into dozens of slices to make specimens. In this way, whether the brain had petechial hemorrhages or blood clots was clear at a glance.

It was also through this method that the forensic examiners ruled out the possibility of the deceased having a cerebral infarction.

Therefore, the focus of the examination was actually the body surface.

Jiang Yuan carefully checked from head to toe. The muscles of the body were generally in a relaxed state. There were small contusions on the neck, but just like the injuries to the heart and lungs, they could only serve as evidence but could not explain the cause of the deceased's death.

While Jiang Yuan was checking, Jacob and the others also followed along to look carefully.

Some needle marks and the like appear smaller when a person has just died and are easier to miss. After a few days, they might be exposed again. Of course, it is also possible, like counterfeit Maotai, to use extremely fine needle holes for injection, but in such cases, the victim usually wouldn't cooperate. If discovered, there should at least be defensive wounds or restraint marks.

Several people carefully looked at the body's armpits, the back of the knees, the groin, the neck, and other parts, all to no avail.

Jiang Yuan pried open the deceased's mouth to observe. The head, already split in two, was slightly inconvenient to open and look at. Jiang Yuan casually took a flashlight to illuminate and examine it. While flipping it left, right, up, and down, he saw a dark purple circular bloodstain appear on the left cheek.

The area of the circular bloodstain was not large, but the position was very interesting.

Jiang Yuan recalled the autopsy report and confirmed that this circular bloodstain was not mentioned in the report.

In fact, don't look at the autopsy report as having a lot of content; it is impossible to include all injuries. A real body and an autopsy report are similar to a doctor's examination report; they describe the main content, and the content can even be said to be evidence to prove a point.

And the detailed autopsy report that ordinary people imagine, like a cautious and detailed investigation, belongs to an ideal height that cannot be achieved in the actual work of the police. Domestic homicide investigations are slightly better. In a place like Malaysia, with its homicide rate and police investment, if you do one case in detail, you wouldn't have to do the rest of the cases.

"Take a photo here." Jiang Yuan instructed the photographer to take a picture of the circular bloodstain.

After the photographer finished, Jacob and his apprentice also looked closely at the bloodstain.

"How does Forensic Jiang think this mark was produced?" Jacob asked directly.

"It should have been a blood blister before; it was left behind after the blister broke." Jiang Yuan paused, and without waiting for Jacob to ask, continued: "The blood blister was produced by covering the mouth."

This pointed directly to the cause and manner of death, and at the same time, pushed this negative autopsy case from a suspected criminal case directly to a criminal case.

Not only Jacob and his apprentice, but the police nearby also became serious.

"If it were death by asphyxiation from covering the mouth, the symptoms in the eyes or face don't seem typical." Jacob paused and hurriedly said: "I'm not questioning, we are just..."

"Forensic discussion." Jiang Yuan's Indonesian was quite good; LV2 was basically enough for unimpeded communication.

Jacob nodded repeatedly: "Yes, just a simple discussion. Because for this case, we actually all suspected the possibility of murder, but in terms of forensic evidence, there are indeed contradictions."

"The atypical symptoms in the eyes and face, from my understanding, have two reasons. First, I think drugs were taken. Under the influence of drugs, the sympathetic nervous system is inhibited, the heartbeat and blood pressure are stable, and the strength of struggle and resistance is very weak, or perhaps there was no struggle or resistance at all."

"Just like being anesthetized," Jacob's apprentice couldn't help but say.

Jacob just nodded solemnly. Jiang Yuan was answering the question, and at the same time, he threw out another argument, which was that the cause of death included the effect of drugs. Thus, the question returned to the starting point: how were the drugs ingested, and what drugs were ingested?

Jiang Yuan didn't care how he considered the details and continued: "The second reason for the atypical symptoms should be that the time of covering the mouth was very short, about three or four minutes. After letting go, the cyanotic swelling of the face naturally subsided. For example, some people die by hanging, but are discovered very quickly. After a few minutes, they are taken down, and the cyanotic swelling of the face is not very obvious."

Jacob nodded gently, more surprised than anything. Jiang Yuan was purely starting from experience, and in terms of age, it should have been him who was more experienced.

The senior police officer nearby, Niza, began to get anxious. He couldn't understand Jacob's thoughts and couldn't help but ask: "So, the victim was first drugged and then suffocated by covering his mouth, is that right?"

"Yes." Jiang Yuan gave a clear answer and said: "The difficulty of this case lies in the unknown cause of death. Currently, no drug poisoning has been detected, the deceased had no obvious diseases, no traces of electrocution, and no traces of neck strangulation. But covering the mouth is certain, and the petechial hemorrhages on the surface of the heart and lungs are also consistent with the symptoms of death by asphyxiation. Of course, acute sudden death can also cause heart and lung hemorrhages, so there is indeed room for discussion regarding the cause of death. But from all aspects, being drugged and then suffocated by covering the mouth is most consistent with the characteristics of death."

Niza looked at Jacob and confirmed a second time: "Forensic Jacob, do you agree?"

Even if Jiang Yuan is a "god," Niza still needs his own forensic examiner to confirm.

Jacob's expression was a bit dazed, and he said slowly: "Jiang Yuan's judgment is the most consistent; I agree."

Honestly, for a forensic examiner, giving a negative autopsy conclusion requires great courage. In terms of frequency, a normal forensic examiner might not give a single negative autopsy in several years, or even ten years.

Jacob reached the conclusion of a negative autopsy because he really couldn't solve it. Moreover, he understood the consequences of this conclusion better than anyone.

If it is a negative autopsy, it actually means that the cause of death cannot be found. Theoretically, it is equivalent to saying that murder does not exist, because no one knows how the deceased died.

Of course, in practice, for the police, they can still investigate the case from the perspective of murder, from motive or other aspects. But pressure is inevitable. This situation is the same as a murder case where the body hasn't been found. There is always the possibility that after all the investigation, it is very likely that the murder case does not exist, and thus there is no real murderer.

Niza couldn't care about Jacob's thoughts now. After getting confirmation, he immediately said: "We now know that the death occurred after the deceased went to bed. The deceased's wife slept in the same bed as the deceased and claimed she didn't wake up in the middle of the night. When she got up in the morning, she didn't feel anything abnormal about her husband. Finally, the nanny went upstairs to call him for dinner and found he was already dead..."

Speaking of this, Niza looked at Jiang Yuan again and said: "In addition, the deceased had long-term extramarital affairs, had a poor relationship with his wife, and often quarreled. The wife has a motive for the crime."

Niza: "Although there is no evidence of the deceased's wife's crime yet, she undoubtedly has great suspicion, at the very least she is a person with knowledge... I suggest arresting the deceased's wife, Dunxiti."

Several senior police officers present expressed their agreement.

They had suspected Dunxiti before, but let alone evidence, even the existence of a murder case was in doubt. Therefore, they could only demand that Dunxiti not leave the city, but could not exert further pressure.

At this moment, the information provided by Jiang Yuan completely changed the passive situation.

Niza took his people and left in a hurry.

Jacob and his apprentice finished up, full of emotion.

Zhong Zhong Renlong sent Jiang Yuan and the others out of the autopsy building.

The family members were still dressed in white mourning clothes, not knowing what had happened in the autopsy room.

"Forensic Jiang, what would you like to eat tonight?" Zhong Zhong Renlong asked with a smile.

Jiang Yuan didn't answer, but the system interface had already popped up before his eyes:

Task: Dragon in the Field

Task Content: A place where cases occur frequently is just right for a forensic examiner to exert their abilities, solving cases until 100 foreign peers regard you as a master detective.

Task Progress: (8/100)

Jiang Yuan didn't expect that among the Malaysian police, 8 people already considered him a master detective, and he couldn't help but smile.

Thinking about it again, Jiang Yuan said to Zhong Zhong Renlong: "Let's go eat durian. Also, bring the case files for a few cases; we can look at them while we eat."
