Chapter 233: Ling Xu's autopsy
Hearing Ling Xu's words, Chen Shaochun looked at him in amazement: "You don't dissect?" So what are you doing with a scalpel? ”
"This is called a wound examination knife, the blade has no edge, and it is a tool for examining all kinds of wounds. Pen, fun, pavilion www. biquge。 After saying this, Ling Xu picked up a lancet from his toolkit: "See?" This is the scalpel, used to dissect cadavers. ”
After putting down the tool, Ling Xu looked at Chen Shaochun with a strange expression, and looked at Chen Shaochun with straight hair: "Why are you staring at me like this?" ”
"No, Captain Chen, you don't know anything about the autopsy, do you?" Ling Xu asked with a suspicious expression.
After hearing this, Chen Shaochun's face turned red, and he retorted unconvinced: "What's wrong with not knowing how to conduct an autopsy?" The owner of the restaurant may not be able to cook, the vegetable seller may not know how to grow vegetables, and the director of some hospitals does not know how to see a doctor. ”
"That's because I don't have a governor, and if I become the director of the Midtown sub-bureau, I will stipulate that the captain of the criminal police must be able to conduct an autopsy." After Ling Xu finished speaking, he handed a notepad and a pen to Chen Shaochun: "The autopsy won't be, then the writing will always be right?" I said, "You remember." ”
After speaking, Ling Xu lowered his head and began to examine Li Yanxin's body: "The head is intact, the chest part is intact, there are two fatal wounds on the abdomen, and the lower body is intact, and it was not violated before death."
There were three scratches on the palm of the deceased, and the scratches were located in the center of the palm and arranged in order, with a length of three centimeters, two centimeters, and five centimeters. The cut is wide and smooth, which excludes the murder weapon, which should have been caused by an object such as glass.
According to the length of the scratch and the depth of the cut, there should be blood stains on the hand, but the photos of the body scene show that there was no blood on the deceased's hand at that time, and no tool was found at the scene to cause the scratch, which is suspicion 1.
The corpse had a slight abrasion on the thumb of the left hand and the middle finger of the right hand, the wound was irregular and circular, the area was about three centimeters in diameter, the surface skin was scratched, and there were traces of peeling, but no peeling epidermis was found at the scene, and no abrasion point was found, which is suspicion 2.
There was a superficial bruise on the elbow of the left arm of the corpse, which was in the shape of a strip, which was artificially forcefully pinched, which should be the traces left by the murderer when he pulled the deceased's arm with his fingers, but no third-party fingerprints were left on the surface of the bruises, which is suspicious point 3.
Li Yanxin died of knife wounds, two fatal wounds, one three centimeters above the body's navel and five centimeters below the heart. The fatal wound was a trauma to the heart, the wound was 23 centimeters deep and 6 centimeters wide, the liver organ was penetrated by a sharp weapon, the nerves and blood vessels of many organs were cut by the blade, the heart organ was directly pierced by the murder weapon, and the heart vein was broken.
The wound at the navel was 11 centimeters deep and 4 centimeters wide, the small intestine was damaged in many places, the wound caused here was a non-fatal injury, the murder weapon was a fruit knife, the blade was 30 centimeters long, when it was found, the murder weapon was inserted into the wound under the deceased's heart, and the surrounding blood stains had coagulated.
Since the body had been frozen in a freezer and the blood stains had been cleaned, it was not possible to examine the clinical changes of the wound and the necrosis of the damaged organs, but according to the results of the forensic examination at the scene, the time of the victim's death was determined to be between 23 o'clock on the night of the crime and 1 a.m. the next day. ”
Ling Xu inspected here, he used tweezers to pinch out a piece of intestine from the wound in the navel of the corpse, and then held the intestine in front of Chen Shaochun, Chen Shaochun was recording, Leng Buding saw the intestine handed over by Ling Xu, he trembled with fright, subconsciously took a few steps back, and looked at Ling Xu with an angry face: "What are you doing?" Want to scare me to death? ”
"I asked you to see this intestine, did you react so much?" Glancing at Chen Shaochun with disdain, Ling Xu stared at the intestines in front of him, and gradually frowned: "The incision of this intestine is white, slightly turned outward, there is no blood in the intestine, and even the incisions of the organs around the small intestine are also shrinking, this is not right." ”
Seeing Ling Xu take out a section of intestines from the wound of the corpse, and the other end of the intestines was still in the abdominal cavity of the corpse, Chen Shaochun smacked his lips with a look on his face, looking at Ling Xu's carefully observed expression, he asked casually: "The intestines have been cut off by a knife, what else is wrong?" Hurry up and stuff the intestines back, I can't stand this. ”
Ignoring Chen Shaochun, Ling Xu said to himself: "The inquest report issued by the forensic doctor where you separated is clearly written that the cause of the victim's death was caused by serious damage to internal organs and excessive blood loss. However, although the damage to these small intestines is very severe, the signs around the wound do not meet the conditions for excessive blood loss. ”
"What do you mean by that?" Chen Shaochun looked up at Ling Xu.
Ling Xu and Chen Shaochun glanced at each other: "Last night, I asked Wanqing to carefully recall the details of that night, according to Wanqing's recollection, after she was led into the dormitory by the so-called female ghost, she saw the corpse on the bed, although the knife was inserted into the deceased's body, but at that time, there was only one wound on the corpse, which was the wound located in the heart.
However, when you found the body the next day, there was an extra wound on the deceased's body, and it is for this reason that I insisted on coming here for an autopsy today, and through the examination just now, I found that the wound on the deceased's navel, whether it was the injury or the location of the wound, was not enough to pose a fatal hazard to the deceased.
In particular, the internal organs in the wound are not in line with the clinical fatal factors. I suspect that Li Yanxin was already dead before this wound was formed, and if this inference is true, then the time of death judged by the forensic doctor before was biased, and the time of Li Yanxin's death is likely to be advanced, before 23 o'clock in the evening. ”
"What? It can't be, right? Chen Shaochun has been engaged in criminal investigation work for many years, and knows the importance of the time of death to the homicide investigation, so when he heard Ling Xu say that Li Yanxin's death time should be advanced, he instantly frowned: "Ling Xu, I hope you don't lie in order to help Mo Wanqing clear his suspicions." ”
"Why am I going to lie?" After asking this, Ling Xu stuffed his intestines back into the wound, and at the same time continued in his mouth: "The time when Wanqing found the deceased was around 24 o'clock, when the deceased had already died in dormitory No. 26 on the tenth floor, and there were blood stains on the ground.
However, there is a lot of evidence missing in dormitory No. 26 on the tenth floor, what is the item that scratched the palm of the deceased? Where is the skin that came off the abrasions on the deceased's fingers? Why are there no fingerprints on the surface of the bruises on the deceased's arm?
On the surface of all this, your criminal police team missed a scene, the place where the murderer should transfer the body in dormitory No. 26 on the tenth floor, and before that, there must be a real crime scene, which is where the murderer killed. ”
