Chapter 294

"Wu Wu Fa Yi Jiang, would you like to take a look at the body?" Ye Tianher, a forensic doctor from the Criminal Investigation Detachment, greeted Jiang Yuan with a smile.

Ye Tianher had dealt with Jiang Yuan during the Wu Wu Longshan wild man case, and they had looked at the bodies of the hikers together.

At that time, Jiang Yuan was still pulled over by Liu Liu Jinghui because of his fingerprint and crime scene investigation abilities, and his forensic skills were not outstanding.

However, Ye Tianher didn't dare to look down on Jiang Yuan.

Not to mention that in the criminal investigation team, being able to solve cases is the greatest god; just in terms of forensic skills, the burnt bone case Jiang Yuan did not long ago also embodied his super-strong forensic anthropology foundation.

Forensic anthropology is almost the commanding height of forensic medicine; just forensic anthropology alone is enough to convince other forensic doctors.

Ye Tianher would absolutely not be the first person to trip up the Changyang Municipal Criminal Investigation Detachment—Yu Yu Wenshu had been working in the Criminal Investigation Detachment for nearly 10 years, and everyone in the detachment had heard the story of his photographic memory and the time he was tripped up.

Especially after Yu Yu Wenshu's repeated practice, the atmosphere within the detachment had become much more harmonious.

Ye Tianher had already finished examining the body and directly gave up his position at this moment.

Jiang Yuan had come to the scene, so he definitely had to look at the body; Ye Tianher was as clear as a mirror in his heart.

Jiang Yuan then stepped forward to perform the examination and asked: "Wu Wu Fa Yi Ye, what is your conclusion?"

"Strangled, probably." Ye Tianher took off his gloves, stretched his waist and back, and said: "There are petechial hemorrhages in the eyeballs and conjunctiva; it's quite obvious."

How to judge whether a deceased person in a hanging state was murdered or committed suicide is considered a primary school graduation exam question for forensic doctors.

Is it difficult? A little bit.

The difficulty mainly lies in comprehensiveness, that is, how many schemes you can propose to judge suicide versus homicide.

If you can state them all, or state about eighty percent, then it counts as primary school graduation level.

Of course, like all similar topics, this topic can also be infinitely complex, becoming a research direction for a master's or even a doctoral degree. But in real cases, criminals with such high academic levels are even rarer.

More importantly, when a criminal researches this aspect so deeply, their performance in other aspects might be even worse.

Petechial hemorrhages in the eyeballs and conjunctiva are one of the schemes for judging suicide versus homicide.

Some people, even if they were strangled, won't have petechial hemorrhages in their eyeballs and conjunctiva; this is the only place that needs attention. If so, when the forensic doctor reaches the autopsy stage, they can also make further judgments by examining the bruising of the neck muscles, as well as the hyoid bone and the superior horn of the thyroid cartilage—generally speaking, that is, generally speaking, those who strangle others often use excessive force, using brute force to a degree that exceeds what is necessary.

To choke or strangle someone just right, the skill involved in this is also very high.

Even so, it is still possible for them to have conjunctival hemorrhage—possibility is such a fascinating thing.

For Ye Tianher, seeing conjunctival hemorrhage and seeing eyeball hemorrhage is basically enough to make a judgment and turn the unnatural death into a homicide case to be handled.

Next, this body definitely cannot be returned to the family; it must be put on the autopsy table for an autopsy, and then look at the situation of the hyoid bone and neck muscles...

However, even if the hyoid bone and neck muscles are fine, the conclusion won't change.

Because the deceased might have been strangled with a cord-like object; this might not break the hyoid bone, but there is a high probability of leaving ligature marks, because the tissue at the ligature site collapses, and the blood vessels also collapse, causing the bacteria that cause the body to rot to arrive late, thus forming marks.

This is equivalent to a highway or a railway transporting supplies being interrupted, and at the same time, the enemy's troop transport route being blocked, so the speed of erosion is slower.

In short, strangling someone to death and faking it as suicide, in this era, is already a bit too difficult; it's better to... right.

Jiang Yuan also had no objection to the cause of death of the deceased, nodded, put on his gloves, and began to examine it up, down, left, right, front, and back.

He had waited for so many days and was already very eager

to try using the newly acquired lv6 skill.

Starting now, the first feeling is... hard.

When a person is about to die, their body becomes stiff.

One hour after a person dies, rigor mortis may begin to appear; it usually reaches the whole body in 12 hours, begins to ease around 18 hours, and the body gradually becomes soft.

So, why some meat companies want to promote the acid-draining meat of pigs is to help you preserve the pork well. Pigs start rigor mortis 8 hours after death, lasting 15 to 24 hours, that is, after 32 hours, the transport is just completed, and rigor mortis is also over. When it reaches the consumer, the meat is just in a soft state and won't feel hard.

And the enzymes in the meat begin to enter a working state; they will degrade the myofibrils, making the meat soft and juicy, which is what everyone often calls not tough. Theoretically, it will also bring more flavor.

Chaoshan beef likes hot fresh meat, which is actually also very reasonable.

Because the rigor mortis of cattle only starts after 10 hours, but lasts for 72 hours. Therefore, good beef should be consumed within 10 hours. 72 hours is really too long; it's better to dry-age it.

By the way, the rigor mortis of fish starts from 0.1 to 0.2 hours, lasting about 2 hours. Therefore, the correct way to eat fish is to cook the fresh fish immediately after killing it, or marinate it for more than 2 hours before eating.

From the examples of pigs, cattle, and fish, a conclusion can also be drawn.

The rigor mortis time and duration of a body are all different.

The rigor mortis time, duration, and even hardness of different people should also be different. This is not only related to a person's fatness, muscles, but even related to the place where a person is located.

This is not regional discrimination, but the temperature and humidity of people in different regions are different, and the types and states of bacteria are different.

Why the time of death of a person is so difficult to judge is because there are too many uncertain factors.

Some forensic doctors who have worked in a certain place for many years often have some unique experience in judging time, which is actually also the reason.

Using an easy-to-understand example, suppose at the same time, a Northeasterner died in the Northeast, and a Hainanese died in Hainan; the Hainanese should have rigor mortis earlier and ease earlier.

And if a Northeasterner died in Hainan, the speed of the appearance of rigor mortis is also related to the time he arrived in Hainan.

Of course, besides rigor mortis and livor mortis, there are many other techniques for judging the time of death of a body. In fact, it is also because everyone has too high a demand in this regard.

For example, the turbidity of the cornea, for example, body temperature; more advanced ones include the eyeball chemical method, measuring the concentration of potassium cells in the eyeball...

Jiang Yuan didn't speak rashly just because he had mastered the lv6 skill.

He still examined the body one by one, trying to obtain more information as much as possible.

Such a high-level death determination skill is no longer just about using a certain technical means well; it is about using every technical means well, and they can verify each other.

So, when Jiang Yuan finished looking, he confidently gave the conclusion: "The time of death is around 10:15 this morning."

Ye Tianher's brow wrinkled slightly.

As a fellow forensic doctor, he actually doesn't like this kind of "around such and such time" statement. Someone like Ye Tianher prefers to give a time interval, from what time to what time, so everyone can see it at a glance.

Some forensic doctors always like to say an accurate time and then add an "around".

This kind of statement looks more confident and accurate, but in fact, the meaning is about the same, and instead, there is a suspicion of misleading.

Yet, after the case is solved, everyone always thinks the former is more accurate.

Ye Tianher shook his head inwardly, only thinking that Jiang Yuan was in a youthful state of mind, wanting to show off a bit.

But as far as the matter itself is concerned, Ye Tianher felt that it should be more rigorous.

"Let's say the time of death is 10:15 to 12:00." Ye Tianher had come earlier and had measured the rectal temperature, feeling that the deviation was not large.

And Jiang Yuan came later, so the accuracy of his judgment must be worse than his.

Ye Tianher could be considered to have saved face for Jiang Yuan;

he had originally judged it to be 11:00 to 12:00. Now he had forcibly moved it forward by 45 minutes, which was obvious enough. Later, he still had to tell the police officers handling the case.

At this time, Jiang Yuan said: "I said around 10:15, and I personally lean towards the left side. I think the more likely time is just past 10:00, that is, the earliest is 10:00, and the latest is no more than 10:30."

Ye Tianher was stunned; this completely diverged from his real time judgment.

The correct time he thought of was at the earliest 11:00. Don't look at the 30-minute difference; these 30 minutes, one is the upper limit of the other party and one is the lower limit of the other party, which is basically two judgment results.

"Let me take another look." Ye Tianher didn't dare to guarantee it anymore; after all, it was a judgment made by Jiang Yuan, and he couldn't bring himself to say no bluntly.

Wan Wan Baoming saw that the atmosphere was a bit tense, stepped forward and smiled: "Everyone's judgment of the time is actually basically consistent; it's normal for this time of death to be off a little bit. I often see it off by an hour or two; the deceased didn't die according to the regulations in the first place..."

Ye Tianher sighed, couldn't help but glance at the outsider Tang Jia in the room, hesitated for a few seconds, and then said: "The deceased's husband came in at 11:40. According to the time of death of the body Jiang Yuan made, the deceased's husband had no time to commit the crime."

Wan Wan Baoming was stunned; the deceased's husband could be said to be full of suspicious points, almost like a tailor-made murderer.

If the determination of the time of death gives the deceased's husband an alibi, that would be ridiculous.

If things go wrong, problems will arise during the death penalty review.

Wan Wan Baoming became serious, looked at Jiang Yuan, and said: "Wu Wu Fa Yi Jiang, why don't you take another good look."

"Okay." Jiang Yuan followed the advice and took another look.

After just a few minutes, Jiang Yuan raised his head and said: "Considering various factors, I think the time the deceased stopped breathing is most likely 10:10."

Pausing slightly, Jiang Yuan also said in a solemn tone: "I understand the situation you mentioned, but the conclusion I gave is absolutely not for the sake of grandstanding."

Jiang Yuan looked at Ye Tianher and said: "Wu Wu Fa Yi Ye, I am purely making a technical judgment and am not targeting you personally."

"I understand." Ye Tianher's expression was still not good, but it had eased slightly.

The expressions of the few people in the room all became serious; the handling of this case was clearly not as easy as imagined.
