civil forensic

The sun is high.

The wind was warm, but everyone at the corpse scene had different moods.

Together, Jiang Yuan and Mei Fang picked up the bones with carrion into a plastic bucket, and the remaining carrion in the snakeskin bag was mixed with corpse water, soil, insect eggs, etc., rippling out a disgusting soup juice.

The bottom of the snakeskin bag has been torn, and it is not known whether it was punctured or drilled by insects.

Jiang Yuan smoothed out his emotions as much as possible. At this moment, there is no cheering environment, and there is no need to say anything about sighing and complaining. Even guessing the case is meaningless.

There were some very smart police officers thinking and pondering, and there were 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 rashly make a decisive judgment at this time.

"The deceased was a woman, about 30 years old." Jiang Yuan got up and moved his waist and legs after catching all the bones, giving everyone a basic message.

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

This is the case with technology, regardless of whether you can be on your own, when you cooperate together, you must have someone who makes decisions.

Especially in forensic medicine, there are regression equations everywhere, and each of them will have different judgments on which one to use.

For example, Mei Fang summed up some commonly used regression equations on weekdays, and the accuracy of the general regression equations is a little higher.As for Jiang Yuan, he actually judged the native place of the deceased first—to be precise, it was the regionality of the race, and then chose which regression equation to use according to the people in different regions.

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

Looking at the length of the foot bone, it is actually within Mei Fang’s range of work, but he usually does not do such a detailed job. The specific regression equation needs to be checked back, but most of them are aware of it.

But at Jiang Yuan's level, the proportions of the tarsal bones, metatarsal bones, and phalanges on his feet are different for him.The width of the soles of different people, as well as the height of the feet, are also very clearly controlled by genes.

A more obvious example is that Nordic people have long feet with less subcutaneous fat, which means they are thinner and thinner. Asians generally have high insteps and wide feet, while South Americans have long and narrow feet.Therefore, when you choose shoes in Adidas or Nike stores, you will generally feel that the size of the shoes is too small, but the width and height are actually insufficient.

In addition, for ordinary people, the difference between the toes may be more obvious.Depending on the length of the toes, there are usually Egyptian, Roman, and Greek feet, and sometimes a square foot is added.

Among them, the Greek foot is called the beauty's foot, and 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.

In China, there was a saying about Greek feet: the second big toe is long, so don't raise your father and mother.

Similarly, when choosing shoes, some people wear pointed-toed leather shoes or pointed-toed high-heeled shoes, and they are always uncomfortable in various ways. It is right to be uncomfortable, because pointed-toed shoes are prepared for Greek feet.

Conversely, the more popular five-finger socks in Japan are very unfriendly to Greek feet, and the too long index toe can easily wear the socks on top, which shows that the proportion of Greek feet in Japan is very low.In fact, most Asians have Egyptian feet. The length of the toes decreases from the big toe to the bottom, forming a slash.

Only the foot type is actually involved in the footprint science, and the different bones, after careful study, are all related to genes.Such as Asian squatting, it is very simple for forensic doctors to explain, because Asians and people from other regions have different proportions of the thigh bones. The length of the thigh bones of Asians is basically the same as the length of the lower legs, so Asian squat.

As

Immigrant countries like the United States will do more research on the relationship between race and body.The ethnicity in China is relatively single, and the gap between different regions is not so obvious, so there are relatively few studies.

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

"Don't use the shovel, call two more people, dig out the remaining corpses with your hands." Jiang Yuan collected the large pieces of bones, and seeing that the remaining corpses had been integrated into the soil, he simply called for someone to use the shovel. hand planer.

Under the watchful eyes of a group of leaders, several young police officers were joined in, and another plastic basin of carrion, soil, and insect corpses was dug up.

"Are you ready?" A police officer was so tired that he wiped his sweat until he smelled the stench, and his face turned green from disgust.

"Spit it far away, and you are not allowed to spit within 15 meters." Jiang Yuan drove the people away, and then said: "Call a few more people, and all the soil within 10 meters of the body bag will be taken 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 doesn't understand forensic entomology, but there are experts in this field in the province, and he can consult them when the time comes.For a case as big as 805, it cannot be like a small case, just find a way to cut in with the lowest cost, solve the case and leave.

The correct approach is to advance multiple ways. If you can go through multiple paths, then multiple paths will be more beneficial when it comes to the trial stage.

Within the scope of the corpse, the forensic doctor does what he says.

Mei Fang hurriedly called more people to shovel the soil one by one.

When a big hole was shoveled around, and the pickup truck that Xu Taining had prepared in advance was also full of rear buckets, Jiang Yuan dragged his gloves again, and said to Liu Jinghui, "I'll go back to do the autopsy, you guys keep busy."

"Okay." Liu Jinghui agreed, and then urged: "Contact 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.

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

A dead body is not only the tragedy of a person, but also the grief of a family.

As far as Xu Taining's experience is concerned, it is definitely not a good thing that corpses are found in such a quick succession in the first phase of the search that has just started.

"I'll go and see now, let's send someone to drive the corpse here." Jiang Yuan directly handed the key to the person next to him.
