Chapter 372: Continuation

The sun was high.

The wind blowing over was warm, but the people at the corpse-lifting scene had different moods.

Jiang Yuan and Mei Fang picked the bones with rotten meat into a plastic bucket together. The remaining rotten meat in the snake-skin bag, mixed with corpse water, soil, and insect eggs, rippled with nauseating soup.

The bottom of the snake-skin bag was already broken, and I don't know if it was poked through or eaten through by insects.

Jiang Yuan smoothed his emotions as much as possible. At this moment, a cheering environment did not exist, and there was no need to sigh or complain, and even guessing the case had no meaning.

There were extremely smart police officers at the scene thinking and pondering, and there were more senior criminal police whose understanding of this case was more than Jiang Yuan's understanding of mutton. They were also waiting for Jiang Yuan to give more clues to combine with the information they already knew to make judgments.

Even Liu Jinghui would not make a decisive judgment rashly at this time.

"The deceased is female, about 30 years old." Jiang Yuan fished out all the bones, got up to loosen his waist and legs, and gave everyone basic information.

Then, Mei Fang measured the length of the long bone of the right leg on the spot, and discussed a height and weight range with Jiang Yuan, and Jiang Yuan said: "Height 168, weight 110."

People who do technology are like this. No matter whether you can stand alone or not, when you cooperate, there must be a person in charge who makes the decision.

Especially like forensic doctors, there are regression equations everywhere. Which one to use and which one not to use, each will have different judgments.

Like Mei Fang, he usually summarizes some commonly used regression equations. Compared with the accuracy of general regression equations, it is higher. As for Jiang Yuan, he actually judged the deceased's ancestral home first—to be precise, the regionality of the race, and then chose which regression equation to use based on people from different regions.

This judgment is based on the differences between other bones. For example, for long bones of the same length, the length of the foot bones of people in some places is different. For example, women in the south have smaller bodies and larger feet compared to women in the north.

Looking at the length of the foot bones is actually within the shooting range of Mei Fang's work, but he usually doesn't do it so finely. The specific regression equation has to be checked when going back, but most of them can be realized.

But when it reaches Jiang Yuan's level, the length and shortness of the tarsal bones, metatarsal bones, and phalanges on the feet are different to him. The width of different people's feet, as well as the height of the feet, are also very clearly controlled by genes.

A more obvious example is that Northern Europeans have longer feet, and at the same time, the subcutaneous fat on the feet is less, that is, relatively slender and thin, while Asians generally have high insteps and wide feet, while South Americans have narrow and long feet. So when picking shoes in Adidas or Nike stores, you will generally feel that the shoe size is small. In fact, it is because of the lack of width and height.

Besides, for ordinary people, the difference in toes might be more obvious. According to the different lengths of toes, there are usually Egyptian feet, Roman feet, and Greek feet. Sometimes a square foot is added.

Among them, the Greek foot is called the beauty foot. Its index finger is 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.

And in China, there was once a proverb for Greek feet: If the second toe is long, you don't raise your father and mother.

Similarly, when choosing shoes, some people wear pointed leather shoes or pointed high heels, which are always uncomfortable in various ways. It is uncomfortable, because pointed shoes are prepared for Greek feet.

Conversely, the five-toe socks that are relatively popular in Japan are very unfriendly to Greek feet. The overly long index toe easily pierces the socks, which shows that the proportion of Greek feet in Japan is very low. In fact, most Asians are Egyptian feet, and the toe length decreases in order from the big toe, forming a diagonal line.

Just the foot type alone involves footprint science, and different bones, if studied carefully, are all related to genes. For example, the Asian squat, for a forensic doctor to explain, is very simple, because the ratio of the size of the thigh bone to the calf bone of Asians is different from that of people in other regions, so Asians can do the Asian squat.

Like

the United States, an immigrant country, will study more about the relationship between race and body. China's race is relatively single, and the gap between different regions is not so obvious, so there is less research.

However, for forensic doctors, subtle gaps are often the focus of breakthroughs.

"Don't use a shovel, call two more people, and dig out the rest of the corpse with your hands." Jiang Yuan collected the large pieces of corpse bones, and seeing that the rest of the corpse had merged into the soil, he simply called people to dig with their hands.

Under the gaze of a group of leaders, several young police officers were added, and another plastic basin of rotten meat and soil, as well as insect corpses, were dug out.

"Is it okay?" A police officer wiped sweat and finished, only to smell the stench, and was so disgusted that his whole face turned green.

"Go to a distant place to vomit, don't vomit within 15 meters." Jiang Yuan drove the person away, and said: "Call a few more people, and bring all the soil within 10 meters of the corpse bag back."

Necrophagous insects will not only eat, sleep, and reproduce on the corpse, they will also distribute around the corpse, and the number within 10 meters is very large.

Jiang Yuan himself does not understand forensic entomology, but there are experts in this field in the province, who can be consulted later. For a case as big as 805, it cannot be like a small case, finding a path with the lowest cost, solving the case and leaving.

The correct approach is to advance on multiple fronts. If you can pass multiple paths, then take multiple paths, which is also more favorable at the trial stage.

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

Mei Fang hurriedly called more people, shoveling soil bag by bag.

After a large pit was shoveled around, and the pickup truck prepared by Xu Taining was filled with the rear bucket, Jiang Yuan took off his gloves and said to Liu Jinghui: "I'll go back to do an autopsy, you continue to be busy."

"Good." Liu Jinghui agreed and exhorted: "Contact at any time."

Jiang Yuan moved the corpse and equipment to another car. When he turned back to talk to Xu Taining, the latter answered the phone again.

When Xu Taining put down the phone, Jiang Yuan had already guessed the result. "Found another corpse." Xu Taining sighed heavily.

A corpse is not only a tragedy for one person, but also a pain for a family.

And judging from Xu Taining's experience, the first phase of the search that had just started actually discovered corpses continuously so quickly, which is definitely not a good thing.

"I'll go see it now, send someone to drive the corpse here." Jiang Yuan handed the key directly to the person next to him. ===== CHAPTER 373 =====
