Chapter 303: Not Easy

"Forensic Doctor Jiang, would you like to see the body?" Ye Tianhe, a forensic doctor from the criminal police detachment, greeted Jiang Yuan with a smile.

Ye Tianhe had dealt with Jiang Yuan during the Wulong Mountain Savage Case, and had seen the corpses of fellow travellers.

At that time, Jiang Yuan was attracted by Liu Jinghui because of his fingerprints and on-site investigation abilities. His forensic skills were not outstanding.

However, Ye Tianhe did not dare to look down on Jiang Yuan.

Not to mention that in the criminal police team, the one who can solve crimes is the biggest god. In terms of forensic skills alone, the bone-burning case that Jiang Yuan did not long ago also demonstrated his strong forensic anthropology skills.

Forensic anthropology is almost the commanding heights of forensic science. Just being a forensic anthropologist is enough to convince other forensic doctors.

Ye Tianhe will never be the first person to trip up in the Changyang City Criminal Police Detachment - Yu Wenshu has been working in the Criminal Police Detachment for almost 10 years. His photographic memory and the story of being tripped by someone are always familiar to him. Everyone in the criminal police detachment has heard it.

Especially after Yu Wenshu practiced it many times, the atmosphere in the detachment became much more harmonious.

Ye Tianhe had almost finished examining the body, and now he gave up his position.

Jiang Yuan came to the scene, and he must show the body. Ye Tianhe felt like a mirror.

Jiang Yuan then stepped forward to do an examination and asked, "What conclusion did forensic doctor Ye make?"

"She must have been strangled." Ye Tianhe took off his gloves, moved his waist and back, and said, "There are spot-like bleeding in the eyeballs and sclera, which is quite obvious."

How to determine whether a hanged person is a homicide or a suicide is a primary school graduation exam question for forensic doctors.

Is it difficult? A little bit.

The difficulty lies mainly in comprehensiveness, that is, how many options can you come up with to judge suicide and homicide.

If you can tell everything, or about 80% of it, then you are at the level of a primary school graduate.

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

What's more, when a criminal studies this area so deeply, he may perform worse in other areas.

Spotted hemorrhages in the eyeballs and sclera are one of the solutions for judging suicide and homicide.

Although some people have been strangled, their eyeballs and sclera will not show spot bleeding. This is the only thing that needs attention. If this is the case, the forensic doctor can also check the bruises on the neck muscles and the hyoid bone at the dissection stage. and thyroid cartilage angle to make further judgments - Generally speaking, that is, generally speaking, people who strangle others often use excessive force and use more brute force than necessary.

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

Even so, he might still have scleral hemorrhage—the possibility is so fascinating.

For Ye Tianhe, seeing scleral bleeding and eyeball bleeding was basically enough to make a judgment and turn the abnormal death into a homicide case.

Next, the body will definitely not be allowed to be taken back by the family. It will have to be dissected on the dissecting table to see the condition of the hyoid bone and neck muscles...

However, even if the hyoid bone and neck muscles were good, the conclusion would not change.

Because the deceased may have been strangled with a cord-like object, which may not break the hyoid bone, but there is a high probability of leaving strangulation marks, because the tissue and blood vessels at the strangulation marks collapsed, causing The bacteria that decayed the body also arrived late, leaving traces.

This is equivalent to the interruption of highways or railways transporting supplies. At the same time, the enemy's troop transportation routes are also blocked, and the rate of erosion is slowed down.

All in all, strangling someone to death and pretending to commit suicide is already a bit difficult in this day and age, so it might as well be...right.

Jiang Yuan had no objection to the cause of death of the deceased. He nodded, put on his gloves, and began to check up and down, left and right, back and forth.

After waiting for so many days, he already wanted to

Try using the newly acquired LV6 skills.

Now that I use it, the first feeling is...hard.

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

Rigor mortis may begin to appear one hour after a person's death. It usually reaches the whole body within 12 hours and begins to ease around 18 hours, with the body gradually softening.

Therefore, why some meat companies promote pig sour pork is to help you preserve the pork. Rigor mortis begins 8 hours after death of pigs and lasts for 15 to 24 hours. That is, after 32 hours, the transportation is completed. , rigor mortis has also ended, and when it reaches the consumer's hands, the meat is just soft and does not feel hard.

The enzymes in the meat begin to work. They will degrade the myofibrils and make the meat soft and juicy, which is what everyone often calls bad meat. In theory, it will also bring more flavor.

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

Because rigor mortis in cattle only starts after 10 hours, but lasts for 72 hours. Therefore, good beef should be consumed within 10 hours. 72 hours is too long, so it’s better to mature.

By the way, rigor mortis in fish starts from 1 to 2 hours and lasts for about 2 hours. Therefore, the correct way to eat fish is to cook fresh fish as soon as it is killed, or marinate it for more than 2 hours before eating it.

A conclusion can also be drawn from the examples of pigs, cows and fish.

The time and duration of rigor mortis of a corpse are different.

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

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 is it so difficult to judge the time of death of a person? There are too many uncertain factors.

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

Using a well-understood example, suppose that at the same time, a Northeastern person died in the Northeast and a Hainanese died in Hainan. The Hainanese should have rigor mortis earlier and relieved earlier.

If a Northeastern person died in Hainan, the speed of rigor mortis was also related to the time he arrived in Hainan.

Of course, in addition to rigor mortis and livor mortis, there are many other technologies for judging the time of death of a corpse. In fact, everyone has too high a demand in this regard.

For example, the degree of corneal turbidity, the body temperature, and the more advanced methods such as ocular chemistry, which measures the concentration of potassium cells in the eyeball...

Jiang Yuan did not speak rashly just because he mastered the LV6 skill.

He still checked the body one by one and tried to get as much information as possible.

Such an advanced skill of death identification is not only the good use of a certain technical means, but also the good use of each technical means, and they can verify each other.

So, after Jiang Yuan finished reading, he confidently gave the conclusion: "The time of death was around 10:15 this morning."

Ye Tianhe frowned slightly.

As a forensic doctor, he actually doesn't like this kind of statement about a certain time. People like Ye Tianhe prefer to give a time interval, from a certain time to a certain time, so that everyone can see it at a glance.

Some forensic doctors always like to say an exact time and then add about.

This statement seems more confident and more accurate, but in fact the meaning is similar, and it is suspected of misleading.

After the case is solved, everyone always thinks that the former is more accurate.

Ye Tianhe shook his head in his heart, thinking that Jiang Yuan was just a teenager who wanted to show off.

But as far as the matter itself was concerned, Ye Tianhe felt that he should be more rigorous.

"The time of death was between 10:15 and 12 o'clock." Ye Tianhe came earlier and had measured the body temperature, so he felt that the deviation was not large.

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

Ye Tianhe also gave Jiang Yuan face.

He originally judged it to be between 11 and 12 o'clock. Now it was forced to be advanced by 45 minutes, which was obvious enough. He had to tell the police officer who was handling the case.

At this time, Jiang Yuan said: "I said around 10:15, I personally tend to the left. I think the more likely time is just after 10 o'clock, that is, 10 o'clock at the earliest and no later than 10:30."

Ye Tianhe was stunned, which was completely different from his real time judgment.

The correct time he thought was only 11 o'clock at the earliest. Don't underestimate the difference of 30 minutes. These 30 minutes are the upper limit and the lower limit of the other party, which are basically two judgment results.

"Let me see." Ye Tianhe didn't dare to guarantee it. After all, it was Jiang Yuan who made the judgment. He couldn't say no.

Wan Baoming saw that the atmosphere was a little tense, and stepped forward and said with a smile: "The time everyone judged is basically the same. It's normal for the death time to be staggered. I often see staggered by one or two hours. The deceased didn't die according to the regulations..."

Ye Tianhe sighed, and couldn't help but glanced at Tang Jia, an outsider in the room. After hesitating for a few seconds, he said: "The husband of the deceased came in at 11:40. According to the death time of the body made by Jiang Yuan, the husband of the deceased had no time to commit the crime."

Wan Baoming was stunned. The husband of the deceased can be said to be full of doubts, almost like a tailor-made murderer.

If the identification of the time of death gives the husband of the deceased an alibi, it will be funny.

If it's not done well, there will be problems when the death penalty is reviewed.

Wan Baoming became serious, looked at Jiang Yuan, and said, "Forensic Doctor Jiang, why don't you take another good look."

"Okay." Jiang Yuan read it again without hesitation.

After just a few minutes, Jiang Yuan looked up and said, "Combining various factors, I think the time when the deceased stopped breathing was most likely 10:10."

After a pause, Jiang Yuan also said in a serious tone, "I understand what you said, but the conclusion I gave is definitely not for sensationalism."

Jiang Yuan looked at Ye Tianhe and said, "Forensic Doctor Ye, I made a purely technical judgment, not targeting individuals."

"I understand." Ye Tianhe's expression was still not good, but it eased a little.

The expressions of several people in the room became solemn. The handling of this case was obviously not as easy as imagined.
