Xu Chu didn't raise his head, but took the tweezers and probed into the so-called trauma on the surface of the corpse and said, "Qian Qian should know that after the corpse encounters fire, the skin will shrink, and then curl up." The degree of contraction generally does not exceed the maximum functional position of the joint, so there will be a fist-like posture. However, there is another situation in the corpse in the fire, that is, the tension of the skin exceeds a certain limit, so that the skin is too tense and produces wounds along the direction of the skin striae, which is suspected to be a trace of trauma. Then there is the corpse due to the high temperature, the skull will be fractured, there will be a large hematoma on the epidural, and it will also be suspected that the head will be hit hard. ”

However, whether it is the former or the latter, a closer look will still reveal signs that are different from the external injuries left by external blows. For example, skin cracking caused by high temperatures is regular and blooms along the texture of the skin. However, it is impossible for the injuries caused by the blow to be obvious and the depth of the injury cannot be the same. ”

"As for skull fractures, it is also the same reason, and there will generally be no epidural hematoma under heavy blows."

Xu Chu said concisely, but the words were clear and easy to understand, even if it was Sikong Han and other laymen on the side, he could easily think of it clearly.

Qian Qizuo was a little dumbfounded at this time, although he was still quite unconvinced in his heart, but he couldn't say anything to refute for a while.

He glanced at Xu Chu with some hesitation, and saw that Xu Chu's expression was serious and solemn, and he seemed to be very dissatisfied with what he said. However, she didn't know what kind of shock these words had on an insider like Qian Chengzuo.

The so-called blood swollen, Qian Qizuo was still a little incomprehensible for a while, but the general meaning was already understood. If you think about it carefully, it seems that there is really some truth, just like what she said before, the muscles suddenly contract due to the high temperature, but the bones cannot contract, so it is not impossible for the skin to exceed its maximum tolerance and finally burst open.

Just when Qian Qian was stunned, Xu Chu had already taken the autopsy knife and tweezers to pry open the lips and teeth of the deceased. After a series of simple examinations, she looked up at the scribe and said, "Excuse me, fill out a new autopsy form for me." ”

The scribe on the side hurriedly nodded, took a blank autopsy sheet and waited.

Xu Chu inspected the deceased's body very carefully, and after measuring the length of the corpse with a half-squatting body, he said, "The deceased, male, is about five feet eight inches long, and he is fat. The corpse was charred black, with unclear facial features, hands like fists, and a large amount of ash in the mouth and nose. ”

As she spoke, she carefully poked her finger into the deceased's mouth and groped for a moment, and only after a moment did she continue, "Laryngeal edema, there is an obvious phenomenon of hot respiratory syndrome, and the cause of death is suspected to be suffocation due to laryngeal edema and other reasons. ”

Thermal respiratory syndrome is one of the most common words used by medical examiners when examining charred bodies.

To put it simply, it is a series of pathological changes after the injury of the respiratory tract and lungs caused by the fire, scorching air, smoke and other harmful gases in the high-temperature environment of the fire field. The most common ones are soot charcoal deposition, black line-like mucous sputum, congestion and edema, bleeding, necrosis and sometimes blisters on the surface of the mucous membranes of the respiratory tract.

"Is it certain that he was burned to death, or if he was badly injured before he died and could not struggle for help?" Xiao Qinglang's gaze swept over the blackened corpse, and then looked at Xu Chu and asked.

Xu Chu nodded, observed in silence for another moment, and then said, "Normally, the production of respiratory syndrome by heat is enough to show that when the fire burns, the deceased is still dead. This is also unique to burns before death, and is the main basis for distinguishing burns before and after death. ”

However, there are exceptions, such as the deceased's heart muscle is strong, so their heart is very compensatory, so when they are subjected to violent injuries or unexpected stimuli, they will be in a state of suspended animation. However, when the external pressure disappears and the appropriate stimulus, such as high temperature stimulation, is encountered, the heart function will be restored again in about a quarter of an hour. In this case, there will also be various phenomena of burning to death before death, but when investigating the case, there will also be deviations."

The latter is not common in the experience of conducting an autopsy, but it is not uncommon. In many cases, the case was brought to a deadlock because of the cracks on his skull and body, which mistook him for being hit hard first, and he lost the ability to resist and was burned to death.

After Xu Chu's words fell, there was no sound on the side. Obviously, among the people present, only she and Qian Qizuo knew the inner truth best, and others sounded like they were surrounded by clouds and clouds.

However, she was not embarrassed by others, and in order to explain more intuitively, she simply took a post-mortem knife and carefully cut the throat of the deceased, and then carefully exposed his internal trachea. But I saw that the trachea was still swollen and blocked.

"Well, that's what hot respiratory syndrome looks like."

As her hand fell, in the blink of an eye, the deceased's throat was completely revealed to everyone. As for the mucus inside, there was also the sputum that looked sticky and stained with black filamentous soot, which became more and more conspicuous under the cold tip of the knife, causing Sikong Han and the others to tumble in their stomachs.

However, Xu Chu didn't care about Sikong Han and the others' somewhat pale faces, and continued to adjust the blade of the autopsy knife to the deceased's mouth.

"In addition, the neck surface of the deceased's teeth in the mouth is rose-colored, and his teeth are bleeding, so it can be basically inferred that the deceased died of suffocation."

Although Sikong Han's face was ugly, he was still convinced by the results of her autopsy. However, Qian Qizuo was a little embarrassed at this time, he frowned and questioned, "I think the color in this person's mouth should be caused by the heat burning, which is not enough to prove that he died of suffocation." ”

Xu Chu nodded, noncommittal to his words, and went straight to take out the liquor from the toolbox.

"Find a cup."

The official on the side got her instructions, didn't dare to delay and question, and hurriedly ran to the people on the side to find a cup.

After he retrieved the cup, Xu Chu poured the liquor into the cup.

Just when everyone was puzzled, Xu Chu had already used tweezers and a post-mortem knife to remove one of the deceased's teeth. With a bang, the tooth was placed in the glass.

"If it's just a strange taste of the color in the mouth, maybe it's caused by burning. However, if the teeth are rose-colored, does Qian Yanzuo think that it will also be caused by burning? She glanced at Qian Qizuo, and her expression remained unchanged, "Because of suffocation, the capillaries in the mouth burst, and then the teeth are stained with blood and rose." And this color, after soaking in spirits, will become more and more noticeable. ”

Sure enough, after another half an hour, the teeth in the glass became brighter and brighter. This made Qian Qizuo also dumbfounded, thinking that he had an autopsy for more than 20 years, but he never knew that his teeth would change color

Xiao Qinglang glanced at Qian Qi, who was a little stunned, which made him subconsciously shudder, and then said with a smile, "Lord Wang, the small autopsy is mostly based on ancient records, and there has never been a mistake, Lord Xu's autopsy method is really unheard of, unheard of, and unseen."

He didn't mean to deny Xu Chu's conclusion, but it was really a prevarication in a hurry. After all, although he is not an official member, he can be regarded as a person walking in the public gate if he can register for an autopsy in the Criminal Department, even if he is a lowly member, it will make people jealous. But if at this time, the results of his autopsy are completely overturned, it will undoubtedly tell everyone that he is not good at learning

When Xu Chu heard him say this, he immediately said with a facial expression, "I only know that I am stubbornly guarding the classics of my predecessors for autopsy, so how can I develop my line?" But if you compare what you have examined with corpses of similar causes of death and similar circumstances, the new knowledge you can gain may not be more convincing than what your ancestors wrote. ”

Qian Yanzuo was reprimanded so lightly, his face became more and more embarrassed, and his heart became even more worried. As for the initial contempt and impatience for Xu Chu, he didn't dare to show half a point at this time.

Xiao Qinglang lowered his eyes and glanced at Xu Chu, who was still squatting on the side of the corpse, with a solemn face, his eyes flickered slightly, and then looked at Qian Chengzuo, and said in a rather cold tone: "Human life is a matter of heaven, there must be no sloppiness, Qian Chengzuo should calm down." ”

With King Jing'an's words, even if Qian Qizuo wanted to find another excuse, he didn't dare. He only nodded again and again, and said in a cold sweat, "What the prince said is very true."

Xu Chu, who was still checking the situation of the corpse, didn't care about the conversation between Xiao Qinglang and Qian Yanzuo, but continued, "If you want to be further sure, I need to dissect it in detail." ”

Xiao Qinglang has always known that Xu Chu is very cautious in the matter of autopsy, and most of them will rely on autopsy when they have doubts. Therefore, seeing that she had such a need at this time, she naturally nodded and agreed.

In fact, not only Xiao Qinglang, but most of the officials and guards who came with them were also accustomed to Xu Chu's dissection. I have to say that the habit in the proverb is very reasonable.

The guards who wanted to follow Xiao Qinglang's side, when they saw Xu Chu for the first time for autopsy, they would look ugly due to nausea and nausea. When I saw her autopsy for the second time, although I was still a little uncomfortable, at least I wouldn't lose my temper. After the third and fourth times, I got used to it more and more, and even felt that the gaffes of others were really useless.

And the officials of the three law divisions are nothing more than this, at most, they sigh with emotion, Lord Xu is really no taboo. However, with the blessing of the rumors outside, coupled with Xiao Qinglang's acquiescence, it seems that the autopsy is not a big deal.
