The Rise of the Peninsula

Chapter 168 0130 – Case Analysis
"Zhou Papi seems to exist!" Su Shuzhen recalled a scene from an old movie.

Liu Xiumin nodded: "At that time, rural people ate rough and hard coarse grains as their staple food, and their teeth were very worn. If they didn't wrap their teeth in advance, they wouldn't be able to chew anything when they got old."

Unexpectedly, a feature of wear and tear that seems easy to be ignored by people can sum up so many things. Park Shangyuan couldn't help but admire Liu Xiumin in his heart.

Liu Xiumin did not stop: "Usually there are six grades of tooth wear. Grade A is a slight wear of the enamel; Grade B is the gradual wear of the enamel; Grade C is the tooth exposed in spots; Grade D is striped. Exposed; by grade E, the tooth is highly worn; by grade F, the pulp cavity is exposed."

"Tooth wear will appear in different age groups. Grade A wear usually occurs under 20 years old, B grade is 21 to 30 years old, C grade is 31 to 40 years old, D grade is 41 to 50 years old, E grade is Between the ages of 51 and 65, the final level, only appears in the elderly over the age of 65."

"Through the comprehensive analysis of the wear and tear of the deceased's teeth, it should belong to the C-level wear, so his age should be between 41 and 50 years old, and combined with the developmental characteristics of the deceased's skull, I can conclude that the specific age of the deceased should be between 45 and 50 years old." between the ages.

"Before the investigation by the criminal police team, I can't be too specific." Liu Xiumin shook her head. Although she had a rough idea of ​​the specific time, this kind of thing is just a speculation and cannot be used as practical evidence. It still needs to be followed up. evidence follow-up.

Listening to her tone, Park Sang-won was sure that the exact age of the deceased might already be known in her mind, but in order to be conservative, Liu Xiumin gave an estimate with an error within five years.

"Liu Fayi, can you tell the time of death of the deceased?" Qiu Xiuzhen still asked.

This time it was Liu Xiumin's turn to think. The skull of the deceased had been severely deformed, and the skull and brain were forcibly removed after death. The cause of death should be intracranial pressure, blood vessel blockage and extracranial pressure, and the left skull of the deceased was removed. The traces of the skull are also obvious, but the skull on the right side of the deceased is neat.

"The skull was torn from the head abruptly, and was pulled off alive." Liu Xiumin's eyes narrowed slightly.

"How could this be? The skull is an extremely fragile part of the human body!" Qiu Xiuzhen said in surprise.

"Yes, the skull is one of the most fragile organs in the human body. Once the skull is ripped off alive, the deceased's skull will be broken immediately, and then die from intracranial hemorrhage."

"But doing so would do too much harm to the deceased, who would do such a thing?" Qiu Xiuzhen's eyes became serious.

"Intracranial hemorrhage, then there are two possibilities, the first is intracranial tumor, and the second is intracranial blood."

"Blood? The blood is the blood in the skull of the deceased?"

Liu Xiumin nodded lightly, and then shook her head: "The first possibility is basically 90.00%, but this kind of situation is very rare. First of all, the blood vessels in the brain are limited. If there are enough blood vessels in the brain, It can support the blood circulation in the brain, and even if it is an intracranial hemorrhage, it can be treated in time, but if there are not many intracranial blood vessels, it is necessary to find the location of the intracranial tumor or blockage of the intracranial blood vessels for resection or amputation. But intracranial tumors The location of intracranial blood vessel blockage is relatively hidden, and the size of the intracranial blood vessel blockage is relatively large. Most people don’t know these locations, and it is impossible to remove intracranial blood vessels and intracranial tumors. These locations are relatively hidden.”

"Then where is the clogged blood vessel in the deceased's brain?"

"The location of intracranial blood vessel blockage may be the intracranial temporal lobe," Liu Xiumin said.

"Intracranial temporal lobe?"

Liu Xiumin nodded, "Yes, the intracranial temporal lobe is located in the center of the temporal lobe, which is a soft acupuncture point and the place where blood vessels are the weakest. If someone uses the position of the intracranial temporal lobe to If you grab it with your hand, then you can cause it to bleed, which can lead to intracranial temporal lobe hemorrhage, which is a condition in which blood in the brain flows into the large arteries in the brain."

These things are all recorded by Liu Xiumin through the computer, so Liu Xiumin doesn't know where the exact location is.

"Then where is this location?" Qiu Xiuzhen frowned and thought for a long time, but she didn't think of any location in her skull that was easier to determine.

"If my deduction is correct, the intracranial temporal lobe should be located one centimeter from the center of the temporal lobe on the left side of the head."

From this point, we can judge the truth of the deceased, and then return to the topic.

"I can only make a rough analysis, but there are still errors. If we want to get a definite answer, we have to wait for the results of the forensic examination."

Hearing what Liu Xiumin said, Park Sang-won quickly understood the deep meaning of this. She meant to use DNA comparison technology to judge the time of death.If the deceased had family members, it would be impossible not to report the crime for such a long time. To report a missing person case at the police station, the first step in the general procedure is to collect DNA and blood samples from the immediate family members of the deceased.

Liu Xiumin means that if the family members of the deceased report the crime, we only need to collect the DNA of the deceased and compare it to find out the family members of the deceased.Then, the exact time of disappearance can be found out from the family members of the deceased. This kind of accuracy rate can be accurate to the day, which is definitely much more reasonable than blind inference.

In this case, he really has no way to refute. After all, they only saw the color of the deceased's teeth turned red, but they didn't know the specific development situation very well.

No loss is a professional forensic doctor.

"Then." Qiu Xiuzhen asked again: "How do we identify the deceased?"

"Identity?" Liu Xiumin shook her head: "There is no need for identification, based on the joints and skeletal characteristics of the body, and then compared with the dna, you can tell who he is.

"However... I want to know, how much do you know about the profession of forensic medicine?" Liu Xiumin then asked again.

"The profession of forensic medicine?" Qiu Xiuzhen didn't understand, but she repeated the word.

"Forensic medicine in the legal field is mainly responsible for the identification and detection of various difficult and miscellaneous diseases, treatment of difficult and miscellaneous diseases, solving cases, and treating diseases. They are respected and sought after by most people in society. Departments are very familiar."

While speaking, Liu Xiumin looked at Qiu Xiuzhen's expression, and saw the expression of surprise and admiration on Qiu Xiuzhen's face.

Can't help but nodded secretly.

It seems that Qiu Xiuzhen is still a smart kid. Although he usually behaves very straightforward and is not good at disguising himself, but sometimes he is very smart and is very suitable to be a police officer.

Such a person should practice a lot, and sooner or later he will become an excellent investigator.

"Then, let's look for the wounds on the deceased first."

After Liu Xiumin said this, she turned around and walked in front of an instrument, and picked up a piece of bone according to the body shape of the deceased.

"The deceased had a fractured left arm, and there was a deep visible bony scar on the bone of the right hand, and the size, width, and height of the skeleton were in line with the bone characteristics of an adult.

"I don't know if it matches the characteristics this person said." Liu Xiumin muttered to herself, and then used a pen to draw the shape of the bone.

"Liu Xiumin, here are a few questions that I think you need to answer for us. Are you interested?"

At this time, Pu Shangyuan couldn't help but ask, Liu Xiumin turned to look at him.

"Speaking."

Pu Shangyuan rubbed his hands shyly, and then said slowly: "What we want to do is to solve the case, but in the process of solving many cases, a lot of technical things are needed, such as autopsy, identification, blood, Teeth, etc. If there are no qualified identification tools, we may not be able to accurately determine whether these corpses and the deceased belong to the same person, so, I think Liu Xiumin has a set of very reasonable identification tools?"

"Oh, so, what kind of tools does Captain Park want?" Liu Xiumin asked lightly.

Park Shangyuan was a little embarrassed, and then scratched his head. Suddenly, what Liu Xiumin said just now appeared in his mind, and he couldn't help but move.

"I would like to ask Liu Xiumin, what kind of detection method is the most effective for general corpse identification tools?" Park Shangyuan asked tentatively. He felt that since Liu Xiumin could say this, he should be very professional, saying Might not really be able to help them.

Liu Xiumin looked at Park Sang-won, and then said with a smile: "I was also researching this issue just now, now we can look for breakthroughs from the corpses, and judge whether they are related to this case from their physical characteristics, so that we can find Some valuable information.

"However, in terms of identification tools, I still suggest that we rely on our own experience to make some more professional identification tools.

"After all, there are still many wonderful things in this world. If a set of professional instruments can be used to identify identification tools, maybe we can find a better breakthrough."

Hearing this, Qiu Xiuzhen also nodded her head: "That's a good statement. If we can find better identification tools, maybe the truth of the case can be surfaced, so that more people won't be wronged."

"Well, I think such a method is feasible."

Park Shangyuan nodded: "Since we are forensic doctors, we must have a clear understanding of the various characteristics of the corpse, so that we can judge what the relationship between this case and the murder case is."

"Yes, Captain Park is right." Liu Xiumin nodded appreciatively.

Liu Xiumin and Park Shangyuan were discussing the case, while Qiu Xiuzhen listened quietly beside her. She could tell that although this man named Liu Xiumin was young, he had a great leadership style. Such a big man, It must be a very powerful forensic doctor, and maybe she can have some unique insights in this case. Naturally, such a person cannot be neglected. No matter whether she can help or not, it is not a bad idea to make a friend first.

However, when thinking like this, Qiu Xiuzhen felt a little depressed again, and sighed in her heart, is such a good opportunity really so rare?
Thinking about it, Qiu Xiuzhen suddenly felt her stomach rumbling, she couldn't help but blushed, she quickly covered her stomach, and looked around in embarrassment.

When Liu Xiumin looked up and saw Qiu Xiuzhen's appearance, she chuckled suddenly: "Secretary Qiu, are you hungry? I don't think you need to eat today's lunch."

Qiu Xiuzhen was taken aback, and when she saw Liu Xiumin's smile, she couldn't help but blushed: "Well... what are you laughing at?"

"It's nothing, I just want to tell you that you don't have this kind of luck every time." Liu Xiumin shook her head, then lowered her head and started to compare.

"By the way, Director Leng, how was the fatal injury of the deceased caused? Why is the wound so strange?"

Qiu Xiuzhen looked like she broke the casserole and asked the bottom line.Liu Xiumin frowned slightly, staring at the two rows of scar-like wounds, lost in thought. "Could it be a business card?"

He suddenly remembered the movie "Young and Dangerous".

"By the way, it's a business card."

Dian Wei slapped his forehead, his eyes lit up suddenly, he seemed to have grasped who the murderer was, who had never seen Young and Dangerous at that time, and no one imagined that he could become Young and Dangerous at that time, killing all directions , The brotherhood of buddies was in that era, and whoever hadn't had blood rampant at his age, it was normal to think of these things.

"Could it be that people from the underworld did it? Isn't this kind of plot too familiar?"

Liu Xiumin had a surprised expression on her face.

"That possibility is not ruled out."

Liu Xiumin shook her head and said, ""

"Oh~!"

Ye Qian nodded half-understood, and then suddenly said: "But if that's the case, could it be that the murderer did it alone? Wasn't it someone from the underworld?"

After hearing this sentence, Liu Xiumin was stunned for a moment. Why does this sentence feel like a line from that movie?
"What's a business card?" Su Shuzhen shifted his gaze to Pu Shangyuan, with a puzzled expression on his face. He hasn't seen Young and Dangerous at his age, so that's abnormal.

But as for some people who don't know what a business card is, as the group leader of several people, it is necessary to introduce it.

"A business stab is a weapon worn on the hand. There are spikes on the top of the bracelet. During a fight, the sharp spikes are like knives and can penetrate any part of the opponent. If the spikes are sharp enough Is it possible to pierce the skull in this case?"

Park Sang-won tentatively asked Liu Xiumin, the first time he had only seen it in movies, but he had never seen it in reality, nor had he seen anyone stabbing others with this kind of weapon, and this kind of weapon should be regarded as relatively Hard to buy is targeted.

Therefore, through this possibility, the possibility of checking the demand can be greatly reduced, but if it is a gangster, it is another matter.

"You said it's very possible. If you use proper force, it's easy to pierce the skull. And I just observed that there are still a lot of dot marks on the skull of the deceased. These marks should be formed by insufficient force, because there is no puncture Through the skull, without our attention."
