The Rise of the Peninsula

Chapter 167 0129 – Who is it?

Several people exclaimed. "Obviously, everyone found this feature."

Pu Shangyuan turned over all the soles of a pair of shoes of the deceased, pointed to the different wear characteristics on the two shoes and continued: "We have all observed that the soles of this pair of cloth shoes are more severely worn, and most of them are concentrated on the forefoot. It must be the stress-bearing part, in other words, the deceased’s forefoot is often stressed, and it has been in contact with a certain place for a long time, resulting in friction, which will cause this situation.”

"Long-term contact with a certain place has caused friction. Could it be a person who walks on tiptoe?" Dian Wei made nonsense heartlessly.

Su Shuzhen somewhat understood what Park Shangyuan meant, but said to Dian Wei with a cold face, "You have the kung fu of smoothing the skin, so you might as well listen to what Prosecutor Park has to say."

Although Dian Wei was a little displeased, he had no choice but to wait for the next one. Seeing that everyone was waiting for his puzzle, he had no choice but to start explaining.

Pu Shangyuan accelerated his speech and said: "This kind of wear feature cannot be caused by normal walking, unless the deceased walked on tiptoe for a long time. If this possibility is ruled out, then I have reason to suspect that this wear feature is due to some kind of occupational habit Forming."

"It's the driver." Su Shuzhen nodded, "When driving a vehicle, we often use the soles of our feet to touch the clutch and the brake and accelerator. There is no doubt about it."

Su Shuzhen paused.

"However, in our daily life, if we only drive during working hours, this situation will not happen, but it will happen to people who make a living in this profession and step on the clutch every day, so it is conceivable. "

"Our answer is about to come out. The deceased may be a driver, but follow-up evidence is still needed."

Pu Shangyuan nodded. Sure enough, a good investigator would get twice the result with half the effort. He had already thought of this kind of thing, but he didn't expect that he would be able to think of it after his own advice.

As expected of an experienced prosecutor, he has achieved the same level as himself in terms of criminal investigation and trace inspection.

Park Shangyuan immediately added, and glanced at the deep pit that was being dug at the moment with slightly worried eyes.

"Anyone who has driven a vehicle knows that the driver will often use the clutch, brake and accelerator when the vehicle is running, so the wear characteristics of their soles are concentrated on the forefoot, and because the right foot needs to step on the brake and the accelerator at the same time. Accelerator, the left foot only needs to step on the clutch, so the right foot is more worn than the left foot. The two shoes of the deceased just fit this feature."

"It is unlikely that one or two drives would have developed such a severe wear pattern, suggesting that the deceased may have been a long-term professional driver."

"There are too many drivers, the drivers of the government, the drivers of large trucks, the drivers of small passenger cars, how can you judge that they are taxi drivers?" high.

Park Sang-won pointed to the deceased's left shoe and said: "There are obvious wear and tear on this pair of shoes, indicating that the deceased's left foot was used to step on the clutch, so he was driving a car with manual transmission."

"We know that manual transmission cars basically belong to the lower configuration of the same model, so some government departments will not purchase them, which rules out the possibility that the deceased was the lead driver."

"General leaders' drivers don't dress so shabby."

"And the most important thing is that the old Seoul cloth shoe on the left foot of the deceased is the most severely worn. We all know that manual transmission cars need to constantly change gears by stepping on the clutch, and they need to change when turning or overtaking, that is to say When the speed doesn’t match your gear, we’re going to hit the clutch and change gears, and that’s absolutely true.”

As Pu Shangyuan's most sincere investigator, Dian Wei added another sentence in a timely manner. "Boss, how to rule out other situations?"

Park Shangyuan was silent, and then looked at Su Shuzhen with a questioning look.

Su Shuzhen recognized this, but he thought about it carefully, and it seemed that there was really no reason to refute it. It seemed that it was true, and he substituted it unconsciously. He thought it was a popular idea, and thought This is the taxi driver, but the fact is really the case, so how to rule out other viewpoints?
Qiu Xiuzhen also said: "In addition, there are truck drivers, bus drivers, and tricycle drivers who have been engaged in driving for a long time, but the specifications of the clutch, accelerator, and brake pedals of each car are different. Different.

Due to the heavy weight of trucks and buses, the forward inertia is relatively large, and it is very difficult to brake, so the pedal surface is relatively wide, in order to prevent the soles of the feet from stepping on the ground in an emergency.For some small tricycles, the pedal surface is relatively small due to the limited operating space of the cab.

Only the sedan's tread is mid-spec.

As he said that, Park Shangyuan looked down at the two shoes of the deceased again, pointed to the worn features and said: "From the above, it is not difficult to see that the most severely worn part of the deceased's soles is rectangular, and the size is basically consistent with the pedal surface of a car. , so I can be sure that the vehicle driven by the deceased is a sedan with less than seven seats, and I can even exclude commercial vehicles and SUVs."

"So what do you say?" Qiu Xiuzhen refused to let go, and looked at Pu Shangyuan with the eyes of a seeker, and then subconsciously glanced at Dian Wei and Su Shuzhen.

Both of them shook their heads helplessly, they really didn't know how to refute this point.

"It's better to observe the degree of wear of the soles, but these are just experiences, and you can naturally conclude after seeing a lot."

It's not that I don't want to talk about it, after all, no matter what subject there is, it's hard to tell Park Shangyuan in front of so many people.

Qiu Xiuzhen saw that Pu Shangyuan said such a sentence perfunctorily, so she consciously did not continue to ask.Park Shangyuan winked at her, and then said: "From the clothes of the deceased, we can see that the clothes on his body are very cheap, but he has been driving a car for a long time, which shows that he is probably a type of person who drives for a living.

"In our city, only taxi drivers meet my inference."

"Your analysis is very reasonable, but you have overlooked one point."

Park Sang-won opened his mouth at this moment. "Which point?"

Su Shuzhen pricked up his ears and smiled.

"The corpses buried deep in the soil are completely boneless. Except for special cases, the general time is between two and four years. In our city, besides taxi drivers, there are also black car drivers. Although our city Black car drivers were basically banned two years ago, but the exact time of death of the deceased has not been determined, and the possibility that he was a black car driver cannot be ruled out."

Su Shuzhen's thinking was really meticulous, and he helped Park Shangyuan make up for this omission in time.Since the scene was outdoors, there were more and more people onlookers.

Liu Xiumin finished stitching all the bones together, and after confirming that there were no missing pieces, Park Shangyuan returned to the department with the on-site inspection materials to prepare for the next step of laboratory work.

As far as the current situation is concerned, the busiest people are Liu Xiumin and her apprentices.One of them has to analyze the bones, and the other has to do a lot of inspection work.

Therefore, Pu Shangyuan and his friends all gathered together in Liu Xiumin's royal room.

This room is usually used for forensic research, and various models of human tissues are placed neatly and orderly in it. In addition, there is an anatomy bed in the middle of the room. This bed does not usually dissect corpses, and only When the forensic anatomy room of the funeral parlor cannot be used normally, it will be temporarily supported.But for the bone case, this bed just comes in handy.

"Forensic Doctor Liu, what shall we analyze next?" Qiu Xiuzhen had the strongest desire for knowledge in Pu Shangyuan's inspection team. "

It is precisely because he is not satisfied at the age of just graduating from college, she still has momentum now, although she is only a clerk, but she is eager to become a prosecutor like herself, so she is not ashamed to ask, there is This kind of thinking gradually changed in her.

Mature?

"We have determined the height of the deceased through measurements at the scene." Liu Xiumin opened her forensic record book and read a value: "The height of the deceased is 1.6 meters five.

Now that we know the height, what we want to analyze next is the gender and age of the deceased.Although the body is now ossified, we can still see some inherent features.

When Liu Xiumin said this, he pointed to the pile of bones in front of him: "Men and women have different physiological functions and engage in physical labor differently, and the bones also reflect gender differences. "

Men's bones are generally thicker and stronger, with obvious protrusions at the attachment of muscles, thicker bone compact, and heavier bone quality;
Women's bones are thinner, with less obvious protrusions, lighter bone quality and smooth surface, and thinner bone density than men's.However, the bones of women who have been engaged in physical work for a long time are not significantly different from those of men.

At this time, it can be judged by the pelvis. Since women undertake the task of giving birth, the size of the upper opening of the pelvis is larger.

Because the sex difference between men and women in the pelvis has already appeared during the fetal period and remains unchanged throughout life, it can be judged that the deceased was a man based on this alone.

There are a total of 206 bones in the human body. This is for adults, and there are more for children. Because the epiphyses of children are not completely closed, there are more.There are 29 skulls, 51 trunk bones, and 126 limb bones.

These bones are also divided into long tubular bones, which are long bones, such as the femur, which is the thigh bone, and the tibia and fibula, which are the two bones of the lower leg, and the humerus, ulna, and radius are all long tubular bones.Flat bones, like skulls, are thin and flat bones.Short bones, like the calcaneus, some of the bones in the foot are short bones.Irregular bone, most of the skull is irregular bone.

"Then how to judge the age of the deceased?" Qiu Xiuzhen glanced at the confident Liu Xiumin, and then asked.

Liu Xiumin had a calm demeanor. Hearing this, he was taken aback for a moment and then looked at the shameless student standing opposite him, but somehow he couldn't help but subconsciously glanced at the rather stern-looking man among them, and then shook his head with a smile. .

Sure enough, there is a team member as long as there is a captain. Park Sang-won once asked himself so reluctantly in the first case in Daegu.

It is said that this is accumulative learning, but in fact it is just stealing. I don’t know what is the use of such a guy learning these things. Is it necessary for a prosecutor to learn so much?
Or it means that he wanted to take the forensic medical certificate, but he persuaded others to study medicine, and his family was ruined.

This sentence is absolutely true.

Studying medicine is a difficult and lengthy thing. Those who can persevere are those who truly love or have persistent perseverance. They abide by professional rules and shoulder the important responsibility of defending, extending and welcoming life.

This is especially important in forensic medicine.

They are not as glamorous as in the reports, just like the profession of prosecutors, they have been deliberately beautified.In fact, forensic doctors work day and night.

If a murder happened at night and the criminal police were notified, and then the police were invited to notify the forensic doctor, then it is conceivable.

After all, murders don't wait until night, and there is no specific time for them to happen. There has never been such a thing as nine to five. If you are free, then the city will really be quiet.

Liu Xiumin stopped her reverie and opened her mouth to explain.

"To judge the age of the deceased, we have to judge according to the most special type of bone in the human body."

Liu Xiumin picked out the skull of the deceased, pointed to the position of his mouth and said: "From the degree of bone development of the deceased, it is not difficult to see that the deceased is an adult, and the most accurate way to judge the age of an adult is to observe the wear characteristics of the teeth. "

"Wear characteristics of the teeth?"

Park Sang-won heard that this term seemed to have something to do with the university's auditory traceology, so he focused his attention.willow
Xiumin glanced at me, and after confirming that Park Sang-won's eyes were focused on the direction of his fingertips, he said: "When people eat food, due to the chewing movement, there is friction between the teeth and the food, and between the teeth. Cause the wear of the occlusal surface and incisal end of the teeth. After the adult teeth are fully developed, there will be almost no changes. Therefore, the degree of wear of the adult teeth will increase with age.

"We can find a lot of clues in this wear pattern of teeth."

"Clue?" Dian Wei shouted a little excitedly.Liu Xiumin nodded, and continued: "Let me give you a few examples, so you can get a general understanding. For example, shoemakers, they often use their teeth to bite the studs, which will cause serious wear and tear on the incisors.

People who like to smoke pipes wear more lateral incisors.

There are also people who have been engaged in sewing for a long time, because they often bite the thread with their teeth, which will also cause the characteristic wear characteristics.

In fact, the most vivid scenes are some scenes shown in old movies. If you observe carefully enough, you will find that the landlords at that time liked to wrap their teeth in gold.
