Chapter 145: Identification with Blood (Three Watches)
……
Later, An Yijing found the girl's diary in a pile of evidence.
An Yijing remembered that on the last page of the girl's diary, such a passage was recorded.
…… When I become an adult, I will have to plan for my future life. I'm going to save a sum of money, find a good day, and take that one on a trip. The world is so big, I have to look around......
This girl, who always had the most beautiful dream in her heart, was forever asleep the night before she turned eighteen.
Seeing An Yijing wandering, the forensic doctor couldn't help but remind her: "What's wrong?" If you're too tired, go and rest for a while. ”
He also knew that An Yijing had just stayed up at Ning's house for three hours straight, so she looked tired now.
Hearing this, An Yijing came back to her senses in an instant, and then shook her head gently, with a faint smile always hanging on the corner of her mouth.
"No, I want to solve this case now."
With that, she immediately threw herself into the autopsy.
Picking up the corpse's hair, An Yijing suddenly found a strange wound on the corpse's head.
This wound is easy to overlook if not looked at closely.
The wound is in the shape of a small U-shape, which is supposed to have been caused by some blunt object.
It's just that what blunt object can form such a strange wound?
Also, there is blood around the hair where the wound is located.
Blood!
An Yijing suddenly thought of something, her eyes lit up, and she hurriedly proposed to the forensic doctor: "Actually, we may be able to use these blood stains to firm the wound, and then find out the fatal wound."
The bleeding state of the wound is an important basis for forensic medical identification of the state in which the wound was caused by the deceased.
Bleeding and injury are inseparable, and injury is a prerequisite for bleeding.
Thus, the injury on the cadaver is usually examined first to distinguish between antemortem and postmortem hemorrhage.
Determine whether the injury is anterior, near-fat, or post-mortem.
When the body is decomposed or the body is not found, and it is difficult to find evidence using a post-mortem examination, it can be identified by observing the characteristics of the blood stains on the scene.
If the deceased is bleeding due to injury before death, the blood gradually flows out of the blood vessels, and coagulated blood stains will gradually form on the wound or the surrounding skin.
NDE injuries are intermediate between antetime and postmortem injuries and are relatively complex.
There is a side that manifests itself as a reaction to life, and there is also a side that is close to death.
At the same time, it is a process, and the early stage of the near-death injury is characterized by the life response of the prenatal injury.
Only to a lesser extent than anterior bleeding is as pronounced and typical.
Late near-death injuries are close to postmortem injuries.
The various life reactions are not obvious.
Post-mortem injury hemorrhage, because the human body stops life, so the injury bleeding has no life reaction.
The wound is pale, there is no contusion around the wound, there is no contraction of the severed muscle, and the wound is no blood clot.
The blood flowing out of the blood vessels after death, if it is accidentally found to be a coagulated blood clot, but it is also loosely combined, and there is a layer of chicken fat-like membranous substance on the surface, which is easy to dissolve and easily washed by water.
……
An Yijing's proposal was quickly approved by the medical examiner.
He nodded approvingly, it was true that the fatal wound of the deceased could be determined by the bleeding state.
So, the two immediately got busy and began to strengthen the wounds of the deceased one by one.
