"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 Barbarian 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 showed 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 stories of people tripping over him every time.
Everyone in the criminal police detachment has heard of 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 immediately gave up his position.
Jiang Yuan came to the scene, and he must show the body. Ye Tianhe felt like he was aware of it.
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 spots of bleeding on the eyeballs and sclera, which are 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%, then you are at the level of primary school graduates.
Of course, like all similar topics, this topic can also be infinitely complicated and become a research direction for a master's or even a doctoral degree. But in real cases, criminals with such a high academic level are even more rare. More importantly, when a criminal
When he studies this aspect so deeply, his performance in other aspects may be even worse.
Spotted bleeding in the eyeballs and sclera is one of the solutions for judging suicide and homicide.
Although some people are strangled, their eyeballs and sclera will not show spotting bleeding. This is the only thing that needs attention.
If so, when the forensic doctor reaches the anatomy stage, he can also make further judgments by examining the bruises on the neck muscles, as well as the hyoid bone and thyroid cartilage angle. Generally speaking, still generally speaking, people who strangle others tend to
Excessive force, using 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 are good, the conclusion will 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, thus forming 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 out 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 an hour after a person's death. Rigor mortis usually reaches the whole body within 12 hours, begins to ease around 18 hours, and the body gradually softens.
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, the meat is just soft and does not feel hard.
The enzymes in the meat begin to work, and they will degrade the myofibrils, making the meat soft and juicy, which is what everyone often calls bad. Theoretically, 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 eaten within 10 hours. 72 hours is really too long, so it is better to mature it.
By the way, rigor mortis in fish starts from 0.1 to 0.2 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.
A conclusion can also be drawn from the examples of pigs, cows and fish.
The rigor mortis time and duration of a corpse vary.
The time and duration of rigor mortis, and even the hardness, of different people should also be different. This is not only related to the person's fatness and thinness, but also to the muscles, and even to the place where the person is.
This is not regional discrimination, but people in different areas have different temperatures and humidity, and different types of bacteria.
The reason why it is so difficult to determine the time of death is that there are too many uncertain factors.
Some forensic doctors who work in a certain place all year round often have some unique experience in judging time. This is actually the reason.
To use a well-understood example, suppose that at the same time, a Northeasterner died in the Northeast and a Hainanese died in Hainan. The Hainanese should have had rigor mortis earlier and relieved earlier.
And if a Northeasterner dies in Hainan, the speed at which rigor mortis occurs is also related to the time he arrived in Hainan.
Of course, in addition to rigor mortis and cadaveric plaques, there are many other technologies for judging the time of death of a corpse. In fact, there is too high demand in this area.
For example, the degree of turbidity of the cornea, body temperature, and more advanced methods such as eyeball chemistry, which measures the concentration of potassium cells in the eyeball...
Jiang Yuan did not speak rashly just because he had mastered the LV6 skill.
He still checked the bodies one by one, trying to get as much information as possible.
Such advanced death identification skills are no longer just about the good use of certain technical means, but also the good use of every technical means, and they can corroborate each other.
Therefore, after Jiang Yuan read it, he confidently concluded: "The time of death was around 11:15 this morning."
Ye Tianhe frowned slightly.
As a forensic doctor, he actually doesn't like the idea of ​​a certain time. Ye Tianhe, like him, prefers to give a time interval, so that everyone can see at a glance what time it is.
Some forensic doctors always like to give an accurate time and then add a few or so.
This statement seems more confident and accurate, but in fact it means the same thing and is misleading.
But after the case was solved, everyone always believed that the former was more accurate.
Ye Tianhe shook his head inwardly, thinking that Jiang Yuan was in a young state of mind and wanted to show off.
But as far as the matter itself is concerned, Ye Tianhe feels that it should be more rigorous.
"The time of death is from 10:15 to 12 o'clock." Ye Tianhe came earlier and had taken the corpse's temperature, so he felt that the deviation was not big.
And Jiang Yuan came later, so the accuracy of his judgment must be worse than his.
Ye Tianhe could be regarded as saving face for Jiang Yuan. He originally judged 11 o'clock to 12 o'clock. Now he forcibly moved it 45 minutes earlier, which was obvious enough. Looking back, he had to tell the policeman handling the case.
At this time, Jiang Yuan said: "I said around a quarter past ten, I personally tend to go to the left. I think the more likely time is just after 10 o'clock, that is, the earliest is 10 o'clock, and the latest is no later than 10 o'clock."
10:30.”
Ye Tianhe was stunned for a moment, as this completely misjudged his real time.
The correct time in his opinion is only 11 o'clock at the earliest. Don't look at it, the difference is only 30 minutes. These 30 minutes, one is the upper limit of the other party, and the other is the lower limit of the other party. They are basically two judgment results.
"I'll take a look." Ye Tianhe didn't dare to give his assurance anymore. After all, it was Jiang Yuan who made the judgment that made him say no categorically. He was still a little unable to say anything.
Seeing that the atmosphere was a bit tense, Wan Baoming stepped forward and said with a smile: "The time everyone judged is actually basically the same. It is normal for the time of death to be staggered. I often see it staggered by one or two hours. The deceased did not follow the regulations.
die……"
Ye Tianhe sighed and couldn't help but glance at Tang Jia, an outsider in the room. He hesitated for a few seconds before saying: "The husband of the deceased came in at 11:40. According to the time of death of the body made by Jiang Yuan, the husband of the deceased had no time to commit the crime.
.”
Wan Baoming was stunned. It can be said that the husband of the deceased was full of doubts, almost like a tailor-made murderer.
It would be funny if the identification of the time of death gave the deceased's husband evidence of alibi.
If you don't do it right, problems will arise during the review of the death penalty.
Wan Baoming became serious, looked at Jiang Yuan, and said, "Forensic Doctor Jiang, please stop taking a closer look."
"Okay." Jiang Yuan read it again calmly.
In just a few minutes, Jiang Yuan raised his head and said: "Based on all factors, I think the time when the deceased stopped breathing was most likely 10:10."
After a pause, Jiang Yuan also said in a solemn tone: "I understand what you said, but the conclusion I gave is definitely not for the sake of sensationalism."
Jiang Yuan looked at Ye Tianhe and said: "Ye Forensic Doctor, my judgment is purely based on technical skills and is not personal."
"I understand." Ye Tianhe's expression was still ugly, but it softened slightly.
