You're Guilty: Conspiracy Scene 2 crime escalation

Chapter 22 The Bubbles in the Heart
The chest and abdomen of Xu Mutian's corpse had been opened.

Accompanied by her assistant, Su Caixuan wore a strict sterile dissecting suit, put on a medical mask to protect her mouth and nose, and held tweezers to carefully examine the internal organs of the corpse.Xu Mutian died not long ago, and has been placed in the refrigerator, but the smell in the opened abdominal cavity is still very strong.Since Su Caixuan became a doctor, she has dissected two or three hundred corpses, but she is still a little sensitive to this smell. After smelling it for a long time, her temples ache.

In Xu Mutian's abdominal cavity, the peritoneum was extensively edematous. It was obvious that he had been severely congested during his lifetime. The inflammatory exudation amounted to several thousand milliliters. A large amount of pus accumulated in the abdominal cavity. The intestinal tube was soaked in the pus. Symptoms of acute peritonitis.Su Caixuan thought, Li Shouquan's diagnosis is fairly correct. This man has a low character, but his medical skills are passable, but the internal organs are generally edematous. It is not easy to determine the cause of the disease, and where did the cyanosis on the corpse come from?

When the tweezers in Su Caixuan's hand touched the stomach wall of the corpse, her heart skipped a beat, the feeling was obviously different.Su Caixuan signaled to the assistant to turn on the spotlight with her eyes, and carefully observed the stomach of the corpse, she couldn't help being surprised.Under the strong light, Xu Mutian's stomach took on a peculiar shape, and half of the stomach wall was almost completely transparent, as thin as a cicada's wing.

The human stomach wall is a tight and solid tissue. The stomach wall tissue is divided into four layers from the outside to the inside, namely, the serosa layer, the muscle layer, the submucosa layer and the mucosa layer. It is precisely because of this that the stomach can accommodate a large amount of food and has extremely Good flexibility.A stomach wall like Xu Mutian's can be broken at the touch of a finger, how can it exist in the human body, wrap and digest food, and complete its mission?
Could this be the cause of Xu Mutian's acute peritonitis?
This idea flashed in Su Caixuan's mind because it was too unimaginable.How can a living person have a stomach as thin as paper?Another more reasonable explanation quickly emerged in my mind-autolysis of the internal organs of the corpse.

The so-called cadaver viscera autolysis refers to the process in which the cells, tissues, and organs of the corpse are destroyed, softened, dissolved, and disappeared under the action of intracellular enzymes after death.

Su Caixuan and her assistant looked at each other, with a tacit understanding, they both accepted the conclusion that the stomach wall of Xu Mutian's corpse had self-dissolved.

But how did the cyanosis on Xu Mutian's corpse come from?Although the degree is not severe, cyanosis spreads all over the body, especially at the extremities of the body such as fingertips and nose.Su Caixuan used tweezers to search the corpse's lungs, testing the degree of swelling of the alveoli, thoughtfully.She moved the tweezers to the surface of the heart again, pressed down gently, and suddenly raised her head and said to the assistant, "Go get a basin of clean water."

The assistant brought water, and Su Caixuan signaled her to turn on the camera to record her process of collecting evidence and keep it as a video material.

When everything was ready, Su Caixuan quickly took out the heart of Xu Mutian's corpse with an autopsy knife, and then gently placed it in the water basin. The assistant watched in amazement as a heart floated on the water, but did not sink.It's really strange, the specific gravity of the heart is much higher than that of clear water, how can it float on the water?
Su Caixuan then did something that surprised the assistant.She raised the autopsy knife and scratched vigorously on the surface of the heart. Wherever the blade touched, bubbles rose in the water.It was only at this point that the assistant suddenly realized, and while recording the video data, he sincerely praised Su Caixuan's professionalism.

Half an hour later, Su Caixuan reported the autopsy results to Li Guanlan: "Confirmed once again that Xu Mutian suffered from acute peritonitis, which was severe enough to cause death. In addition, the real cause of Xu Mutian's death was air embolism."

Li Guanlan was refreshed, knowing that the results of the autopsy had yielded something, so he listened intently.

Su Caixuan said: "When I performed an autopsy on Xu Mutian's corpse, I found that his pericardium was not abnormally enlarged, but the volume of his heart was obviously much larger than that of ordinary people. Combined with the cyanosis on his corpse, I removed his heart. Cut it off and place it in water for inspection. A large amount of gas overflows from the left and right atria and ventricles, and bubbles are generated in the water. It is estimated that the total amount of gas exceeds [-] milliliters. For ordinary people, after [-] milliliters of air enters the blood circulation system, it will block the arteries and veins, causing severe circulatory failure and death immediately. Xu Mutian's heart contained ten times the lethal amount of gas, which was the direct cause of his death and also the cause of the cyanosis on the surface of the corpse. After Xu Mutian fell ill and was sent to the hospital, He was declared dead in less than two hours, and his attending doctor, Li Shouquan, did not perform an operation on him, so the gas entering Xu Mutian's blood vessel was not a complication caused by the operation, but was deliberately injected into Xu Mutian's body, most likely by using an infusion bottle as a tool of crime.”

Li Guanlan pondered and said: "Using air embolism to kill people, we have come into contact with similar cases in the past. From a professional point of view, how long does it take for such a large amount of gas to enter the human body?"

Su Caixuan said: "A few minutes is enough. Once it happens, it is almost impossible to rescue."

Li Guanlan said: "Then the case is very simple. Xu Mutian was forcibly injected with air after he was sent to the hospital. That is to say, the person who had contact with him within 10 minutes before his death is the suspect."

Su Caixuan said: "At that time, there should be people coming and going in the emergency room, which was a bit chaotic. The murderer was able to complete the crime process quickly without being discovered, and he was almost certainly a well-trained medical staff."

After figuring out the clues, Li Guanlan led Feng Xinran to Quzhou City People's Hospital immediately, and asked Zhou Zhuxiu and Li Shouquan to learn about Xu Mutian's situation before he died.

Zhou Zhuxiu disregarded the responsibility and said: "As an administrative cadre, I am not involved in the specific treatment process. Li Shouquan is more clear about this aspect."

Li Shouquan hurriedly said: "The thing is like this. After District Chief Xu was sent to the hospital, he was in a critical condition. The hospital leaders attached great importance to it and asked us to save District Chief Xu at all costs. We are conducting blood tests and imaging on District Chief Xu. After the examination, it was preliminarily determined that he was suffering from acute peritonitis. Immediately, the most capable medical staff in the hospital were organized to discuss the condition, diagnosis and treatment plan, and prepare for the operation. But half an hour later, the nurse informed me that District Chief Xu was critically ill, and I rushed back to the emergency room. The chief was unconscious, and he was declared dead after 5 minutes. That is to say, I was not by his side within half an hour before his death."

Feng Xinran heard that these two people were in a hurry to clear up the suspicion, there was no lack of bureaucracy and flattery to power in their words, and he felt disgusted in his heart, and before Li Shouquan could finish speaking, he interrupted him: "You are the attending doctor, just tell us, when Xu Mutian comes In the 10 minutes before his death, no one touched him, needless to say other irrelevant things."

Li Shouquan said: "Yes, yes, head nurse Guo Meijuan and nurse Zhao Yingying have been with District Chief Xu, and a male nurse, who seems to be called Qiao, is also with them."

The two criminal policemen asked Zhou Zhuxiu to arrange an empty office, and had separate conversations with the three suspects, trying to find clues from their confessions.

Quzhou People's Hospital has allocated the most powerful medical team for Xu Mutian. The nursing team is led by the head nurse Guo Meijuan. Zhao Yingying is also an excellent nurse with 20 years of work experience. Model staff of the People's Hospital.

Although the three made statements separately, their confessions were consistent.The three of them stayed with Xu Mutian in the emergency room for half an hour before his death, never leaving a single step.Guo Meijuan and Zhao Yingying gave Xu Mutian infusions and injections, and monitored Xu Mutian's heartbeat, blood pressure and other indicators.Qiao Baitao was on the side assisting the two.After Xu Mutian was sent to the hospital, he infused two bottles of normal saline, which were mixed with anti-inflammatory drugs.The two bottles of normal saline were taken by Zhao Yingying from the storage room dedicated to the nurses' station.

Guo Meijuan and Zhao Yingying have rich work experience. Although they are busy, they can testify to each other. It was impossible to inject a large amount of gas into Xu Mutian's body.

Qiao Baitao didn't have any chance to get close to Xu Mutian except to help the patients dispose of the waste.

Li Guanlan was slightly disappointed.Previously, he thought that this was an extremely simple case. It took only a few minutes for Xu Mutian to die, which minimized the range of suspects and revealed the murderer.But after interrogation, all three appeared to be unsuspected.

Guo Meijuan and Zhao Yingying have the best chance of committing the crime, but they testify against each other. There are only two possibilities. One is that both of them are innocent and the murderer is someone else;If the first possibility is true, then the murderer seems to be an invisible person, which is contrary to common sense.The second possibility is more likely, but what is the motive of the two committing the crime?Moreover, the two jointly took care of Xu Mutian, which was appointed by Li Shouquan, how could the two reach a tacit agreement to jointly kill Xu Mutian in the shortest possible time?
Both of these possibilities are small probability events.Is there a third possibility?

The two detectives returned without success.After returning to the police force, Li Guanlan ordered Feng Xinran to lead someone to investigate the backgrounds of Guo Meijuan and Zhao Yingying, especially their private lives, whether they had any emotional entanglements or affair with Xu Mutian.Including their family members, whether they have been tortured by Xu Mutian.This is the only thing Li Guanlan can think of at the moment, Guo Meijuan and Zhao Yingying's potential motives for committing the crime.Besides, there was nothing in the case worth pursuing.
