"The deceased, Peng Zihang, male, 24 years old, single, 176 cm tall, 61 kg in weight, professional real estate sales consultant, worked for a real estate agency.
In the autopsy laboratory, Zhou Qianxin was staring at an investigation report, then glanced at the corpse on the autopsy table and said, "Prepare for the autopsy." ” The assistant on the side asked, "Section chief, didn't the victim's family disagree with the autopsy?"
"Forced autopsy" Zhou Qianxin glanced at him and said: "In criminal cases, we have the right to compel the autopsy of the victim's body with an unknown cause of death, you remember, our obligation is to notify the victim's family to be present, not to obtain the consent of the family, he likes to come, even if he doesn't come, understand" "Got it."
The assistant nodded, and stood aside to take notes.
Zhou Qianxin took an 18-gauge dural lumbar puncture needle and a 5 ml disposable syringe, selected the third intercostal space of the left chest of the corpse, completely inserted the needle into it, pulled out the needle core, connected the needle tube with some air, pushed air into the needle to achieve unobstructed needle, and then sucked back the syringe to form negative pressure, and then slowly withdrew the needle outward.
After retreating about a few millimeters, I finally succeeded in extracting my heart's blood.
She waited for a while, continued to suck back the syringe, and did not withdraw the needle completely until about 3 milliliters of blood was drawn, injected it into the test tube, and handed it to the assistant and said, "Take it to test the hemoglobin concentration of alcohol and carbon monoxide in the heart and blood." ” "Okay."
The assistant took the test tube and immediately complied.
Then she picked up the scalpel and prepared for the dissection.
Starting from the neck, a sharp knife is slashed to the pubic symphysis.
Then, she held a knife against the ribs of the corpse to quickly cut the muscles, used scissors to cut the junction between the ribs and the costal cartilage, and then pinched the sternum with both hands and quickly cut off the tissue on the back of the sternum with a scalpel.
In this way, the corpse's chest cavity was opened.
"There is no foreign body in the victim's lungs and respiratory tract, which can rule out the possibility of choking on vomit into the respiratory tract and choking."
Zhou Qianxin observed: "In addition, the pectoralis major muscle is obviously cherry red, the blood in the heart chamber is not coagulated, and it is also cherry red, and the possibility of death from carbon monoxide poisoning is very high." ” "But the special smell of alcohol is equally strong, so it's hard to draw conclusions for the time being."
She cut open the abdominal muscles again, cut open the peritoneum, and the intestines in the abdominal cavity immediately gushed out, emitting a disgusting and disgusting smell.
After pulling her hands for a moment, she found the victim's stomach and duodenum, and quickly cut it open, and took a look: "The stomach is empty, and there is a small amount of chyme in the duodenum. ” "There were no ulcers on the stomach and intestinal walls, and no bleeding spots were seen.
In this way, although the victim consumed a lot of alcohol, it should not be fatal. ” As she spoke, she turned her head to look at her assistant: "Hey, it's been more than half an hour, are you coming out soon?"
"Just came out."
The assistant quickly stood up and said, "Section chief, the content of carbon monoxide hemoglobin in the deceased's heart and blood was positive, which was nearly five times higher than the normal value, which was enough to cause death quickly.
In addition, the blood concentration of alcohol is about 270 milligrams per 100 millilitres, which meets the standard for acute alcohol poisoning, but does not reach the lethal level. ” "Then it is clear that the victim died of acute carbon monoxide poisoning."
Zhou Qianxin took a long breath, walked to the side and took off her gloves and white coat, and said at the same time: "You immediately stitch the body and send it to the freezer, and I will report to the Yu team after typing out the autopsy report."
By the way, give me the inspection order. ” The "good" assistant hurriedly handed the test report to Zhou Qianxin, and she left the dissection room directly with the report.
After another few dozen minutes, the autopsy report was typed, and she came to the outside of the team leader's office on the third floor, and saw that Yu Chen was looking down at something, so she coughed dryly and knocked on the door.
"Xiao Zhou, come in."
Yu Chen looked up suddenly, and when he saw that it was Zhou Qianxin, he immediately put down the file in his hand and stood up and said, "How is it, the autopsy report is out."
"Hmm."
Zhou Qianxin walked into the office, put the autopsy report on the table, and said: "The victim's concentration of carbon monoxide hemoglobin is very high, but the blood concentration of alcohol is not fatal, and the autopsy does not show the presence of foreign bodies in the respiratory tract and lungs, which can be determined to be a death from carbon monoxide poisoning." ” Yu Chen picked up the report and glanced at it, and said, "Cheng, I've worked hard for you, hurry up and rest." ” "Uh-huh."
Zhou Qianxin put her hand on the desk and asked with interest: "Ask, how is the situation in the trace examination department, I am very interested in this case." ” "Not much progress."
Yu Chen shook his head with a wry smile and said: "The footprints and fingerprints at the scene have been surveyed and examined, all of which were left by the victim, and the village where he lives is basically not monitored, so I can't find out who has entered and exited the scene of the crime." ” Zhou Qianxin asked again: "Who did the deceased drink with on the night of his murder, did you find out?"
"Got it."
Yu Chen said: "On the same day, Peng Zihang was rated as an excellent salesman, and he invited many colleagues and friends to drink in a good mood.
At present, the person who sent him back is suspected of committing a major crime, but the people who drank together that night were all so drunk that they can't remember when or how he left. ” "There is no better way but to question them one by one to see if the suspect can be found.
In addition, I will call up the monitoring of the restaurant that night and ask the staff, hoping to get something out. ” "That's right."
Zhou Qianxin thought about it, the forensic autopsy work was over, and she couldn't help much for the time being, so she said, "Then I'll go back first, call me if you need to." ” "Wait."
Yu Chen picked up the file he had just put down, took out a photo from it and handed it to Zhou Qianxin, and asked, "This is a photo taken on the spot, I always feel that there is something weird, you see." ” "Oh" Zhou Qianxin took the photo curiously.
She followed a piece out of the scene, and she didn't find anything strange at the time, but when she heard Yu Chen say this, she should have made a discovery, so she took a closer look.
After looking at it for a while, she suddenly noticed the shoes next to the bed and said, "Team Yu, do you see if it could be a problem with these shoes?"
Yu Chen took back the photo and glanced at it twice, and said, "There's no problem, although the two shoes are a little far apart, and one is still on its side, but it's strange that you can still put your shoes neatly after being drunk."
"Not this one.
Look at the team, is there a shoe print on the edge of the bed?"
Zhou Qianxin said, pointing to a place on the photo.
After speaking, her eyes suddenly lit up: "I probably know how the murderer entered the scene
