The wind was warm, but everyone at the scene of the corpse exhumation had different moods.
Together, Jiang Yuan and Mei Fang picked up the bones with carrion in the plastic bucket. The more carrion left in the snakeskin bag was mixed with corpse water, soil, insect eggs and other substances, creating a disgusting soup.
juice.
The bottom of the snakeskin bag has been torn. I don't know whether it was punctured or caused by insects.
Jiang Yuan calmed down his emotions as much as possible. At this moment, there was no cheering environment. There was no need to sigh and complain. There was no point in even guessing about the case.
There were many smart police officers thinking and pondering at the scene, and there were also more senior criminal police officers who knew more about this case than Jiang Yuan knew about mutton. They were also waiting for Jiang Yuan to give more clues.
Make judgments based on the information you already know.
Even Liu Jinghui would not make a decisive judgment rashly at this time.
"The deceased was a female, about 30 years old." After Jiang Yuan picked up all the bones, he stood up, moved his waist and legs, and gave everyone a basic message.
Then, Mei Fang measured the length of the long bone of her right leg on the spot, and then discussed a height and weight range with Jiang Yuan. Jiang Yuan said: "Height 168, weight 110."
That's what it's like to be a technical person. Regardless of whether you can take charge alone, when you work together, there must always be someone who makes decisions.
Especially for forensic medicine, there are regression equations everywhere. Which one should be used and which one should not be used, everyone will have different judgments.
Mei Fang, for example, summarized some commonly used regression equations on weekdays, which are more accurate than general regression equations. As for Jiang Yuan, he actually determined the place of birth of the deceased first - to be precise,
It is the regional nature of race, and then choose which regression equation to use based on the people in different regions.
This judgment is based on the difference between other bones. For example, long bones of the same length may have different lengths in people's foot bones in some places. For example, women in the south are taller than women in the north.
Smaller, bigger feet.
Looking at the length of the foot bones is actually a job within Mei Fang's range, but he usually doesn't do it in such detail. The specific regression equation has to be checked back, but most of them can be aware of it.
But when it comes to Jiang Yuan's level, the proportions of the tarsus, metatarsal bones and phalanges on his feet are all different for him. The width of different people's soles and the height of their feet are also very clearly controlled by genes.
.
A more obvious example is that Northern Europeans have longer feet and less subcutaneous fat, which means they are more slender and thinner. Asians generally have high insteps and wide feet, while South Americans have long and narrow feet. So in Adidas or Nike
When choosing shoes in a store, you will generally feel that the shoe size is too small. In fact, the width and height are insufficient.
In addition, for ordinary people, the difference in toes may be more obvious. Depending on the length of the toes, there are usually Egyptian feet, Roman feet and Greek feet, and sometimes a square foot is added.
Among them, Greek feet are called beauty feet because their index fingers are the longest. At the same time, people with Greek feet usually have slender limbs and slender feet. Many ancient Greek and Roman sculptures also chose Greek feet.
In China, there was a saying about Greek feet: If the second big toe is long, it will not support your father and mother.
Similarly, when choosing shoes, some people always feel uncomfortable when they wear pointed-toe shoes or pointed-toe high-heeled shoes. It’s okay to be uncomfortable, because pointed-toe shoes are just for Greek feet.
On the other hand, Japan's more popular five-toe socks are very unfriendly to Greek feet. An overly long index toe can easily push through the socks. This shows that the proportion of Greek feet in Japan is very low. In fact,
Most Asians have Egyptian feet, with the length of the toes getting shorter from the big toe down, forming a diagonal line.
Just the shape of the feet actually involves footprints, and different bones, upon closer inspection, are all related to genes. For example, the Asian squat is very simple for forensic doctors to explain, because Asians and people from other regions
The proportions of the large and small leg bones are different. The length of the thigh bone of Asians is basically the same as the length of the calf bone, so they can do Asian squats.
like
Immigration countries like the United States will do more research on the relationship between race and body. China's race is relatively homogeneous, and the differences between different regions are not so obvious, so there is less research.
However, for forensic scientists, subtle differences are often the focus of breakthroughs.
"Stop using the shovel. Call two more people to dig out the remaining corpses with your hands." Jiang Yuan collected the large pieces of bones. Seeing that the remaining corpses had been integrated into the soil, he simply called for help.
Hand plane.
Under the watchful eyes of a group of leaders, several young police officers joined in and dug out a plastic pot of carrion, soil, and insect corpses.
"Are you ready?" A police officer was so tired that he wiped his sweat away before smelling the stench. He was so disgusted that his whole face turned green.
"Go to a distance and vomit. No vomiting is allowed within 15 meters." Jiang Yuan drove the people away and said, "Call a few more people and take back all the soil within 10 meters of the body bag."
Necrophilic insects will not only eat, sleep and breed on corpses, they will also be distributed around the corpse. There are a lot of them within 10 meters.
Jiang Yuan himself does not understand forensic entomology, but there are experts in this field in the province who can be consulted when the time comes. For a case as big as 805, you cannot just look for the lowest-cost way to solve the case like a small case.
Just leave.
The correct approach is to pursue multiple approaches. If multiple paths can be taken, then multiple paths will be more beneficial at the trial stage.
Within the scope of the corpse, whatever the medical examiner says is what it says.
Mei Fang quickly called for more people, shoveling sack after sack of soil.
When a big hole was shoveled around and the pickup truck Xu Taining prepared in advance was filled with the back bucket, Jiang Yuan pulled on his gloves again and said to Liu Jinghui: "I'll go back and do the autopsy, you guys continue to be busy."
"Okay." Liu Jinghui agreed and said, "Contact me anytime."
Jiang Yuan carried the body and equipment into another car, and when he turned around to talk to Xu Taining, the latter answered the phone again.
By the time Xu Taining put down his phone, Jiang Yuan had roughly guessed the result. "Another body was found." Xu Taining sighed heavily.
A corpse is not only a tragedy for a person, but also a tragedy for a family.
Judging from Xu Taining's experience, it is definitely not a good thing to find corpses so quickly in the first phase of the search that has just been launched.
"I'm going to go see it now. Send someone to drive the body here." Jiang Yuan directly handed the key to the person next to him.
