Finding the direction is more important than how many tasks have been completed.
Before turning over the leather shoe, Jiang Yuan was actually not sure about the direction of the next investigation - this is the case with applied forensic anthropology. You don't know what you will find on the bones, so you have no way to preset a position. .
Of course, information such as age, gender, height, etc. are the basis of forensic anthropology and can be determined by finding bones. There is no directionality at all.
The appearance of leather shoes at least proves one thing: the murderer did not carefully handle the victim's belongings.
At the very least, if you weren’t careful enough to take off your leather shoes, you probably wouldn’t have emptied your pockets. The murderer was actually quite panicked, especially if it was the first time he killed someone, and he abandoned the body in a place like the fish pond at the entrance of the village. Logically speaking, if you want to streamline the corpse's belongings, you should streamline them in advance, rather than just simplifying them when the corpse is abandoned.
Of course, because the cause of death of the deceased is still uncertain, the murderer may also have been killed by the fish pond. In that case, the same situation applies. It is basically impossible to carefully clean up the belongings of the deceased, but it is possible. Become a breakthrough in the case.
As an investigator, if the murderer is detected without making any mistakes, this is indeed a manifestation of his ability. But if he can catch the murderer's mistakes and break through in one fell swoop, he can still achieve his goal.
Reality is not a competition. Even for a "super detective" like Jiang Yuan, solving the case is the first priority. To expect a highly intelligent opponent or an evenly matched enemy is to flatter European and American culture. Chinese people never You need this kind of thing to prove yourself.
If we must aim high, Chinese-style ambition is to conquer the world and reform society, not to defeat someone.
After discovering the leather shoes, Jiang Yuan was not in a hurry to trace the source. It was not until Shen Yaowei dug out all the footwear evidence in the "evidence pile" and inspected them all that Jiang Yuan handed over the task to Shen Yaowei.
It would be best if the identity of the victim could be contacted or discovered through the shoes themselves, or through items such as belts.
Although clothing has a large sales volume and has many origins and distribution links, it has never been a good item for traceability, but it is still a good clue.
After thinking carefully, Shen Yaowei proposed: "Captain Jiang, I want to take this shoe to the manufacturer for inspection. Because as far as I know, each batch of shoes is likely to be made of specific materials. It changes. Especially the glue on the surface, the material of the leather, the tanning process, etc. Maybe it can be matched to a specific batch."
"Okay." Jiang Yuan agreed. Although even if it is specific to a certain batch, it may not be possible to determine the identity of the victim, but it is a good clue.
Shen Yaowei immediately rolled up two stinky, bloated shoes, carefully put them into the evidence bag, and started calling the manufacturer.
Jiang Yuan waved and started the artificial conveyor belt again.
At Jiang Yuan's signal, the conveyor belt moved even slower.
Jiang Yuan felt that he needed more time to think.
Crunch.
Liu Jinghui and Lang Heng came after hearing the news.
The two quickly looked at the photos of leather shoes and belts. Lang Heng was a little surprised at first and said: "You found the shoes worn by the deceased through the bones. Your judgment is quite good."
"Actually, it's not difficult to penetrate the well, but there are more points that need to be considered. The main reason is that the deceased's shoes have been worn for a long enough time." Jiang Yuan paused, stopped the conveyor belt again, and Jing explained:
"For example, for people with flat feet, the middle of their shoes is prone to wear and tear, which is not the case with shoes for people with good arches. In addition, it is common for people who walk with splayed feet to have their shoes wear out.
There will be eccentric wear on the outside of the sole."
Jiang Yuan put his hands flat and gave an example: "For another example, a person with ankle valgus will wear out the outside of his soles. And ankle valgus and flat feet are closely related. If you are old enough and do not correct it, a
It is easy for people to have ankle valgus and flat feet at the same time. The corresponding ankle varus and high arches are also closely related, and the inner soles of the shoes are prone to wear. "
Jiang Yuan simulated the movement of the ankle, and then said: "The deceased's left side was hit once, and the ankle bone was fractured. Therefore, the shoes worn by the deceased would have uneven stress on one side. This
It is very easy to judge. This is easily confused with scoliosis and pelvic abnormalities, so I looked at the spine and pelvis of the deceased. In addition, the wear marks on the deceased’s knees can also be used as evidence from the side...
Lang Heng listened blankly.
Two forensic doctors from Changle City were at the scene, with innocent smiles on their faces. Some things can be understood as soon as you hear them, but don't really think that you can understand them just by listening to them.
Forensic anthropology is similar to antiquarianism to a certain extent. They are both techniques, with a little bit of art. What they hear in their ears is logic, and what they see in their eyes are feelings. But they can use other people's knowledge.
Live and other people's money to prove that you are right.
"It'll be great if you find something." Lang Heng could understand the expressions of the two subordinates and knew that the topic was beyond the scope of the topic, so he decisively chose to trust them.
Liu Jinghui thought for a moment and said: "We have found the belt and leather shoes, plus the shirt worn by the deceased. We may be able to guess the image of the deceased."
