Chen Shi rushed into the autopsy room and saw the silent body lying on the table. Peng Sijue was sitting on the ground. Several interns were shaking him: "Captain! Captain!"
"Old Peng, what's the matter with you?"
Peng Sijue stared, as if his soul was gone, and it took a full minute before he said, "Who did it?"
An intern said guiltily: "I put my phone on the test bench in the morning to charge it, and I forgot, it exploded somehow."
Another intern scolded him: "I asked you to change your mobile phone and use that brand. Didn't you read the news?"
"Go and check if there is any damage to the equipment." Peng Sijue stood up with Chen Shi's help, clutching his chest and said: "I'm scared to death."
"Haha, you have such a lovely time." Chen Shixu was surprised and smiled.
"Who let you in like this? Get out!"
Chen Shi saw an extremely conspicuous scar on the corpse's abdomen and asked, "What's going on?"
"If you want to see, change to sterile clothes."
Chen Shi put on a sterile suit and came in. When Peng Sijue was about to open it, Chen Shi said, "Wait, look at this bulging stomach, it won't be an explosive, right? This corpse passed through the hands of those people, or be careful. Wonder, is there a metal detector?"
"What age is it, and the metal detector?" Peng Sijue gave him a blank look and ordered his subordinates, "Go to the fourth floor to borrow a drug detector."
Peng Sijue first inspected the body surface of the corpse. There were six stab marks on the right shoulder of the deceased, but none of them were fatal. There were some bruises on the body, which seemed to have occurred in a fight. The time of death should have been two days ago. It has been discovered that there was a needle eye in the leg of the deceased, and the pupils were constricted. It is suspected that the injection of drugs caused the death.
Chen Shi said: "It seems that he, like Zhou Xiao, did not accept the invitation, so he was killed."
"How did you know?" Peng Sijue asked.
"Zhou Xiao told me, don't be surprised when you hear that, I saw the serial killer at his house... It's a pity that he let him run away."
Peng Sijue remained silent for a long time, and whispered: "You must be prepared to expose your identity."
"It won't be too long, it won't be too long." Chen Shi murmured, with Zhou Tiannan's accidental death, his group of subordinates will finally go crazy, but they will definitely be destroyed.
Soon his subordinates took the instrument that Peng Sijue wanted. The full name of this thing was a drug bomb detector. It could detect tiny particles of drugs and explosives. After inspection, it was confirmed that it was safe. Then Peng Sijue cut the suture on the abdomen of the silent.
The bloody internal organs were exposed, and Chen Shi instinctively resisted. He frowned and looked in, but found no foreign matter.
But Peng Sijue had seen the structure of the human body countless times and found something wrong at a glance. He picked up the kidney tube with tweezers and said, "Look, this kidney was already necrotic. This kidney was sewn up later... and here, this piece. The liver is also sewn up."
"This kidney is definitely not his own. I seem to understand that the person who killed him replaced the lost organ for him. This is a kind of respect. The criminal's respect to the criminal made him leave a whole body. "
"Whose one belongs to this kidney and this liver?"
"I guess it's Qin Wanmu who was missing at the same time, no, I can't bear this scene, goodbye..." Chen Shi patted Peng Sijue on the shoulder when he left, "The case is over, let's go out to relax."
"I'm free on Saturday." Peng Sijue replied without looking back.
"see you then."
After Chen Shi left, Peng Sijue and his assistants went to work. They separated the deceased’s abdominal cavity. Peng Sijue saw that the deceased’s liver was very bad, showing signs of edema and necrosis. He said, “Make a pathological section of the liver.”
The organs of the deceased were taken out in the same way, weighed, pericardial blood, urine, and stomach contents were taken. The cause of death may be poisoning. Finding the target organ is equal to half of the success. He noticed that the main cardiovascular system of the deceased was dilated, pupils contracted, Acute kidney failure, severe liver disease.
There was no pungent odor in the stomach contents. The poison was injected into the body and acted on the liver and kidneys. He thought of arsenic compounds and ordered his subordinates: "It may be arsenic poisoning, do an X-ray diffraction analysis, hair and nails Also take samples for testing."
Half an hour later, the subordinates came in and reported: "Captain, the analysis result is not arsenic."
"How is the blood test result?"
"Blood potassium and white blood cells are above average."
Peng Sijue immediately thought of something and murmured: "Snake venom?" He said, "Do a urine test to see if myoglobin is positive."
He checked the lymphatic organs of the deceased, and the pathological characteristics did not match the snake venom. He suddenly thought of something that the deceased was a mental patient. He should take phenothiazines for a long time. The liver has long been necrotic, so it cannot be used as poisoning. index of.
The increase in white blood cells may be caused by the deceased's struggle and injuries before his death.
How to explain the increase in blood potassium? He suddenly thought that the pupils of the deceased contracted. This was an abnormal phenomenon, because the pupils of the normal deceased would dilate. Could it be drugs
Subsequent urine tests confirmed that it was not snake venom, and Peng Sijue calmly ordered: "Chromatographic analysis!"
He continued to check all the organs of the deceased. One hour later, his subordinates reported excitedly: "Captain, there is cocaine in the urine of the deceased."
"Let me see."
He took off his gloves, handed this to his assistant, and personally checked the identification results. There were indeed drug residues in the urine, and the proportion was still high. In order to confirm that he performed liquid chromatography tandem mass spectrometry identification on the blood.
The results showed that not many drugs were injected into the body of the deceased, and the dose was far from lethal. Because the deceased had no history of drug abuse, cocaine had a strong effect on the organs and successfully interfered with forensic judges on poisons.
This can be said to be a technical level of anti-reconnaissance, where the killer sets up interference objects to make the real poison "invisible".
Peng Sijue remembered the teacher's teaching that there is no undetectable poison in the world, there are only undetectable methods, so he made a decision: "Craniotomy, brain dissection!"
A few hours later, Peng Sijue fell into confusion. All the methods were used, metal poisons, biological poisons, plant poisons, drugs, alcohols, anesthetics... all of these were not right. The things that every forensic doctor had imagined in his student days happened. Poison that does not come out!
If there is an unidentifiable poison, it means that the murderer can kill as he pleases, but cannot be prosecuted, because this can be interpreted as an ordinary sudden death.
"Make another..."
Peng Sijue didn't give up, and when he turned his head, he found that several assistants were all leaning against the wall, stumbling asleep.
He called them up, and the assistant rubbed his eyes and said, "Captain, it's twelve o'clock!"
There are no windows here. He didn't notice at all. He has been working for ten hours without eating, drinking, or even sitting. Peng Sijue said tiredly: "Go back, and write an appraisal report tomorrow morning."
"How to write it?"
"Acute poisoning... The poisoning substance is unknown!"
