And many women who are forensic doctors are not icebergs, just like Su Yaxin, they are almost overactive.

"The scalp is normal, there is no fracture of the skull, the occipital bone is fragmented, there is blood coming out, but there are no signs of intracranial hemorrhage, there is no abnormality in the brain tissue, the mucosa of the deceased has a mucosal damage in the mouth and nose, and the heart blood and costal cartilage are extracted as backup."

Now we use costal cartilage to make samples for the DNA of deceased people, because the exclusion of a human mosaicism and the abnormality of the test data caused by the blood transfusion has just been completed, which will cause the results to be biased.

Xiao Dong conducted a preliminary analysis of the victim's female corpse and extracted the required samples, Su Yaxin took an anal thermometer to test the anal temperature of the deceased, and analyzed after obtaining a set of data: "The accurate time of death should be between 2 and 3 o'clock in the morning, and the cause of death is currently shock due to excessive blood loss in the aora caused by the fragmentation of the occipital bone, and then check the trachea." ”

In order to analyze the suffocation of the deceased, I also came to a forensic step of picking out the tongue, which is actually the abbreviation commonly used by forensic doctors, which means that the tongue in the mouth is pulled out from the neck, and then the entire set of internal organs can be separated from the body. This method is usually used when forensic histopathology is required, where all visceral sections are taken and analyzed under a microscope.

I used a finger to go deep into the throat of the deceased and touched the tongue of the deceased, and then used a lancet to separate the neck of the deceased, and the moment I separated the trachea and esophagus, I touched the cricoid cartilage and thyroid cartilage of the deceased, which is a significant feature of suffocation death, and at this moment Su Yaxin suddenly said: "This kind of mark should be caused by human hands. ”

The thyroid cartilage, which forms the anterior and lateral walls of the larynx, consists of quadrangular left and right cartilage plates with interfacing anterior margins.

The "V" shaped notch above the Adam's apple is called the upper notch, and the posterior edge of the left and right plates is free and protrudes upwards and downwards, which are called the upper and lower angles. The superior horn is longer, connected to the greater horn of the hyoid bone by a ligament; The small horn is shorter and associated with the cricoid cartilage.

Xiao Dong was curious: "Why didn't you hang yourself?" ”

Su Yaxin looked at her: "The death of self-hanging was not caused by suffocation, some people believe that the self-hanged person died of cervical vertebra fracture caused by excessive support during self-hanging." In fact, this statement is not absolute, the cervical spine as one of the fragile parts of human beings, when subjected to a large force from the outside world, it will indeed cause some damage, but only if it hangs itself, it will not cause breakage.

What we call a broken neck and death is a kind of "pedal hanging" that prevailed in ancient times, by making the prisoner's body fall quickly, all the strength of the body is concentrated in the neck, which leads to a great tension on the neck, resulting in a disconnection between the cervical spine and the bone marrow, and when the weight is too large, it is possible to directly pull the person's head down, which is a cruel punishment.

Therefore, in what we often call death by hanging, the real cause of death is actually the lack of oxygen to the brain. In the neck of the human body, in addition to the trachea and cervical vertebrae, there are also the presence of large blood vessels, which are what we call arteries. When hanging, the blood vessels in the neck are compressed by the weight of the body itself, preventing blood from flowing to the brain.

Therefore, the human brain will soon produce a signal of lack of oxygen, and many people will even regret it under the action of survival instinct due to the pain caused by self-hanging, but it is too late at that time, so the self-hanger will often have traces of struggle to scratch his neck! ”

Xiao Dong immediately came to his senses, and took out a pen and paper to record, this guy really has to work hard, otherwise it will be enough to choke at that time, I ignored her, the next step has been opened The deceased's chest cavity has been separated from a lot of muscle tissue, and then straight into the pericardium!

"There is nothing wrong with this heart, the color is fresh and tender, the structure is good, theoretically it should be very good, I cut the coronary artery, well, and I didn't find any signs of stenosis, even if this person's previous routine was not very good, he didn't like exercise, and he sat in a position for a long time, but his cardiovascular function was still healthy, which was given to her by her parents good genes." I said.

"Ha, but if it goes on like this, there will always be some impact, senior, something is wrong, you see that there are signs of bleeding at the tip of the heart." Su Yaxin took the hemostat and pointed out a certain location for me to see.

I looked at it with the help of a head-mounted electron microscope and a probe, and found that there was indeed a bleeding spot in the place, "Do a pathology biopsy to see if she has any underlying coronary heart disease." ”

"Yes!" Su Yaxin moved quickly, and after a while, she completed the visceral section, and put it into the glass slide, plus the coverslip, and checked it first, at this time Xia Xiaoling came in, she took the video recorder that a police officer helped us shoot just now, and said, "Haven't you finished it yet?" ”

"Almost, now let's dissect the muscles of her limbs!" I replied, cut the limbs of the deceased respectively, but this step did not find anything special, my attention returned to some cases of the deceased vomiting blood, this blood I analyzed it is mainly produced by the stomach, at this moment Xia Xiaoling didn't know if he thought of something, and suddenly said: "Is this compensatory menstrual syndrome?" ”

"Huh? Do you know this term too? ”

"Well, of course, this disease refers to periodic bleeding that occurs outside the uterus during menstruation. Most of the diseases occur around the onset of menstruation, or during menstruation, and are often accompanied by decreased menstrual flow or even amenorrhea. The most common clinical bleeding is nasal mucosal bleeding, and others include conjunctival bleeding, external auditory canal bleeding, hematochezia, nipple hemorrhage, hemoptysis and even skin bleeding. Traditional medicine calls this 'menstrual reverse', and severe conditions can lead to anemia. ”

"That's a good point, but compensatory menstrual syndrome is mostly bleeding from the eyes, and the blood is generally not too big, if it is vomiting blood in the mouth......" I haven't finished talking at the moment, Su Yaxin analyzed some of the deceased's conditions so quickly: "Senior, rule out the possibility of lung cancer of the deceased, do a tuberculin experiment to rule out tuberculosis, and do parasite and fungal cultures, these will take time!" ”

"Don't worry, let's rule it out step by step, how is the CT film?"

"I'm doing it, um, it's out, there is no tuberculosis in the lungs, the hemorrhage is normal, and I used an upper fiber bronchoscope to look for bleeding spots!" Su Yaxin replied skillfully using the bronchoscope to operate, if it is a living person, it may be dangerous to use the upper fiber bronchoscope in this case, because if there is a blood clot during the operation, then this person may go to see God.
