Yuan Youchong was a little surprised, what Xiao Xu said was somewhat unexpected to him, but it seems that there is also some truth.
Even Zhou Qianxin glanced back at him, and then said: "Our forensic autopsy work basically follows a sequential principle from easy to difficult, from the outside to the inside, from the appearance to the essence, first find the clues that are easy to find and summarize, and then do tedious work." ” "How to say, this purpose itself is indeed to obtain the most clues and evidence in the shortest possible time, after all, criminal investigation work, especially in the early stage of work, and in serial cases, time is quite precious."
"In this respect, your answer is correct, but in a different direction."
Xiao Xu pursed his lips, obviously a little happy.
Yuan Youchong also nodded with satisfaction.
Answers like this after thinking about it are naturally the most impressive, and will be deeply imprinted in his mind.
During the internship and probationary period, it is undoubtedly the most malleable time, and his discoveries one by one, a little bit of accumulated experience, will eventually form his case-handling and work habits and style.
Yuan Youchong then asked: "What did you find after that?"
"First of all, He Rui's corpse."
He was obviously a lot more confident, his tone was less hesitant, more determined, and he spoke a little faster, saying: "The corpse was badly missing, occupying at least two-thirds of its previous body weight, leaving only the head, about one-thirteen of its torso, mainly the spine, and being cut into multiple pieces, with only six segments and a small number of internal organs.
This part of the corpse is pale, like the severed hands and feet found earlier. ” "Among them, the remaining small piece of liver provides us with a lot of information, the liver is not only an important metabolic organ of the human body, but also the largest blood bank, when acute trauma causes massive bleeding, the maximum can release 1,000 to 2,000 milliliters of blood for the human body."
"Therefore, in the identification of death from acute hemorrhagic shock, I believe that liver examination is the most important.
The remaining small liver of He Rui is lighter in color than the normal liver, and microthrombosis can be seen in the hepatic sinusoids and venules, and the degeneration and necrosis of the central stem cells of the liver lobules, which is a typical pathological change of shock. ” "According to this, although we did not find any ante-mortem injuries in He Rui's remaining body parts, it is enough to determine that he died of hemorrhagic shock caused by acute injuries."
After hearing this, Yuan Youchong hummed, and then looked at Zhou Qianxin.
Although he has dabbled in forensic science, after all, he has relied on self-study, and has not studied systematically, what Xiao Xu said, whether the details are correct or not, he really can't judge, he can only rely on Zhou Qianxin.
Zhou Qianxin received his gaze, the corners of her mouth raised slightly, and said: "Generally correct, but the determination of the cause of death, except for the typical characteristics and pathological changes formed by some special causes of death, in most cases, it takes a combination of multiple examinations to finally determine, and there is no statement of which examination is the most important."
"For example, in the identification of death due to hemorrhagic shock you mentioned, there are actually pathological changes in many organs of the body, and their typicality is no less than that of the liver."
"For example, in the central nervous system, cranial neurons can be seen with ischemic constriction or swelling, glial cell swelling, widening of the space around nerve cells and small blood vessels, and loose and edema of brain stromal structure."
"In the digestive system, for example, there is congestion of small blood vessels in the mucosa of the gastrointestinal tract, leakage bleeding, erosions and stress ulcers.
In addition, the heart, lungs, and kidneys also have many typical features. ” "Moreover, in many cases, the cause of death is quite complex, and it is likely to be the result of a combination of factors, such as primary injury combined with complications, such as toxic effects combined with mechanical asphyxia caused by tracheal obstruction, and then massive acute bleeding leading to acute attacks of certain chronic diseases."
"Therefore, in the actual autopsy work, the pathological changes of a certain organ under the lethal mode are the most typical, and the idea that the examination should be focused on must not be had."
"What you should know is that for a certain type of death, which organs should be examined instead of which parts and parts, and the results of multiple tests are combined to have objectivity."
"Otherwise, once you rush to conclusions, you are likely to form a preconceived notion that will be difficult to reverse, and the report will be biased and biased, leading to the wrong direction of the investigation."
"When deciding to autopsy, regardless of the location of the injury before death, and what the preliminary cause of death is, three chambers must be opened, that is, the thoracic cavity, the abdominal cavity and the cranial cavity, and each organ must be carefully examined and the root cause of the biopsy must be done, which is here."
"Our forensic science, like clinical medicine, must also follow the core theme of evidence-based medicine, and must ensure that the identification results are scientific and objective, understand?"
Xiao Xu nodded again and again, signaling that she had listened.
The young forensic doctor chuckled: "Director Zhou, it's good that he can know that the liver test results have important reference significance for the identification of death due to hemorrhagic shock, don't be too demanding, I was not as good as him when I first graduated from the internship." ” "No," Zhou Qianxin shook her head and said seriously: "The plasticity during the internship is the strongest, and it should be guided more intensively, otherwise once it is formed, it will be difficult to reverse it once it is formed and the thinking inertia is formed."
I'd rather he didn't know about this knowledge than that he would try to take a shortcut in autopsy work because of this knowledge. ” "No matter how powerful the forensic doctor is, even if he can see the cause of death and fatal injuries at a glance, he must honestly complete the autopsy step by step, and the root cause is here."
"It's just that they can tell their subjective judgment to their colleagues in the field as soon as possible, give them a direction as a reference, and when the autopsy is over, they still have to submit an autopsy report, and if there is a discrepancy with the previous judgment, they will change it as soon as possible."
The young forensic doctor pursed his lips and stopped talking.
Yuan Youchong coughed dryly, and then said: "That, Xiao Xu, just said, He Rui died of hemorrhagic shock is undoubted, and then?"
"Well, and then it's time for Liao Wenjue's body to be examined."
Xiao Xu said: "After the personal identification of the corpse parts and the same identification work were completed, that is, after it was determined that these corpse pieces belonged to Liao Wenjue, we further determined that Liao Wenjue's body parts were relatively complete, and no important organs and body parts were missing. ” "Secondly, after identification, it was found that there were several antemortem injuries on the corpse parts, one was blunt force trauma, in the back of the head; The rest are cut wounds and are located in the neck.
