Chapter 393 Continuation

The sun is high.

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.

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 are also waiting for Jiang Yuan to give more clues to make judgments based on the information they 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 fished out all the bones, he stood up and moved his waist and legs, giving 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 be on your own, 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.

For example, Mei Fang has summarized some commonly used regression equations, which are more accurate than general regression equations. As for Jiang Yuan, he actually first determined the place of origin of the deceased - to be precise, the regional nature of the race, and then chose which regression equation to use based on the people in different regions.

This judgment is based on the differences between other bones. Like long bones of the same length, the lengths of people's foot bones in some places are different. For example, women in the south are smaller and have larger feet than women in the north.

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 he reaches 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 slender and thinner. Asians generally have high insteps and wide feet, while South Americans have long and narrow feet. Therefore, when choosing shoes in Adidas or Nike stores, 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 between 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: The second big toe is long and 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.

Foot shape alone is actually related to footprints, and different bones, upon closer inspection, are all related to genes. For example, the Asian squat is very simple to explain by forensic doctors. It is because the proportions of the large and small leg bones of Asians and people from other regions are different. The length of the thigh bones of Asians is basically the same as the length of the calf bones, so they can do Asian squats. squat.

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 are relatively few studies.

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 hands with sweat before he smelled the stench. His whole face turned green with disgust.

"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 not only eat, sleep and breed on corpses, they also distribute around the corpse, and 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, it cannot be like a small case, just find the lowest cost way in, solve the case and leave.

The correct approach is to advance in multiple directions. If you can take multiple paths, then take multiple paths. It will be more advantageous when it comes to the trial stage.

Within the range of the corpse, what the forensic doctor says is what it is.

Mei Fang quickly called more people to shovel soil one sack at a time.

When a large pit was shoveled out around and the pickup truck prepared by Xu Taining in advance was filled with dirt, Jiang Yuan took off his gloves again and said to Liu Jinghui: "I will go back to do the autopsy, you continue to be busy."

"Okay." Liu Jinghui agreed and reminded: "Contact me at any time."

Jiang Yuan carried all the corpses and equipment to another car. When he turned around to talk to Xu Taining again, the latter answered the phone again.

When Xu Taining put down the phone, Jiang Yuan had roughly guessed the result. "Another corpse was found." Xu Taining sighed heavily.

A corpse is not only a tragedy for one person, but also a family's grief.

And based on Xu Taining's experience, it is definitely not a good thing to find corpses so quickly in a search that has just started.

"I'll go check it out now. Send someone to drive the body over here." Jiang Yuan handed the key directly to the person next to him.
