Chapter 1571: Cause of Death

Seeing Ling Ruonan weeping aggrievedly while Wu Yue lowered his head, looking dejected, Luo Ziling finally couldn't bear it.

He wiped his hands on the apron, took out a tissue from his pocket, and wiped away the tears on Ling Ruonan's face.

"Mom, why don't we have a good chat after dinner later," Luo Ziling said softly, "Wu Yue and I will tell you everything, and you can make a decision after listening. What do you think needs to be remedied?" Yes, you decide."

"Okay," Ling Ruonan took the tissue, wiped away her tears, and then told Wu Yue, "You go out first, and report anything at any time."

"Yes," Wu Yue nodded and walked out.

Luo Ziling and Ling Ruonan continued to be busy in the kitchen, but they didn't say anything else. In the kitchen, except for the sound of the range hood, there was only the sound of cutting and cooking vegetables. The atmosphere was very dull, which made Ling Ruonan feel very depressed. , which made Luo Ziling feel very uncomfortable.

However, neither mother nor son knew how to break the dullness.

When Luo Ziling and Ling Ruonan thought of being angry, there was chaos in the VIP ward of Yanjing People's Hospital, about three kilometers away from where they lived.

Suddenly, everyone was stunned.

Yang Yunzhong, a VIP-level patient whose injuries had stabilized after staying with them for nearly a month, suddenly deteriorated. The medical staff rushed to rescue them immediately, but in the end the rescue failed. The line on the ECG monitor that indicated the heartbeat Straighten slowly.

After more than an hour of rescue, the hospital finally announced that the patient died.

When Yang Yunzhong's condition deteriorated, the hospital immediately called the police. The police rushed to the hospital as quickly as possible and controlled the floor of the ward where Yang Yunzhong lived. Most of the leaders of the hospital also rushed to the ward within a short time.

After announcing the death of Yang Yunzhong, the doctors who rescued him at the scene wrote down the rescue case and handed it over to the police.

The doctor in charge of Yang Yunzhong also reported the cause of Yang Yunzhong's death to the hospital leadership.

"The patient was injected with a large amount of potassium chloride, resulting in cardiac arrest and death." This is what the doctors involved in the rescue wrote in the case, and the cause of death reported by them.

It was precisely because it was discovered that a high concentration of potassium chloride was artificially injected that the hospital called the police immediately.

Before Yang Yunzhong was declared dead,

The police who arrived at the scene discovered the abnormal situation.

A nurse in this ward was found unconscious in the dispensing room with her overalls stripped off.

After the police discovered this situation, they immediately checked the surveillance in the ward.

Surveillance showed that the nurse came out soon after entering the dispensing room.

Because the nurse wore glasses, a mask on her face, and a hat on her head, there was no abnormality seen from the monitoring.

The nurse pushed a cart out of the dispensing room, and she went directly to the ward where Yang Yunzhong lived.

There were bodyguards guarding the door of Yang Yunzhong's ward, but they didn't check the nurses.

After the nurse went in, she came out in about a minute.

When she came out, she also said a few words to the bodyguard guarding the door.

What was said, the monitoring system without audio collection could not tell.

After the nurse pushed the medicine changing trolley away, she walked to the ward on the other side and disappeared from the monitoring range of this monitoring, but soon appeared in another monitoring.

After she walked to the ward closest to the elevator, she looked back at the monitoring direction, then put the medicine changing cart at the door of the ward, and walked towards the elevator. After the elevator door opened, she walked in.

The police continued to trace the surveillance in the elevator and found that the nurse had gone to the laundry room in another ward and never appeared again.

Police officers went to the laundry room immediately and found a set of nurses' overalls that had been changed in the laundry room, but no one was in it.

After inspecting the laundry room, the police found that the next door to the laundry room was the bathroom.

After discovering this situation, they continued to check the surveillance and found that several men and women had entered and exited the bathroom for a period of time after the nurse disappeared.

After looking back and forth at the surveillance screen, the police finally discovered that the number of people entering and leaving the bathroom was different, and one more person exited the bathroom than entered the bathroom.

In other words, the "nurse" left from the bathroom.

After a strict comparison, the police locked down a woman in a pink down jacket, a woolen hat, and a mask on her face.

After the woman left the bathroom, she took the elevator downstairs again.

But what is depressing is that the surveillance of that elevator was broken, and there was no surveillance video left.

After the police reviewed all the surveillance videos in the hospital, they still failed to find the woman again.

All the surveillance videos in the nearby neighborhoods were called. The police used a large number of personnel to check all the surveillance videos in the nearby area, but they still failed to find any clues. In other words, the woman just disappeared out of thin air.

The situation is also very clear. This is a man-made murder case. Outsiders disguised themselves as nurses and injected a large dose of potassium chloride into Yang Yunzhong's body, causing Yang Yunzhong to suffer cardiac arrest and die.

During the rescue, the medical staff also performed electrolyte and other biochemical tests on Yang Yunzhong.

Among them, the blood potassium concentration was as high as 18.7mmol/l, which was several times the normal upper limit of 5.5mmol/l.

Simultaneously with hyperkalemia, there are many abnormal indicators.

Originally, Yang Yunzhong's biochemical indicators were basically normal, but the subsequent abnormality should be the result of hyperkalemia.

The large amount of potassium chloride injection led to Yang Yunzhong's death, which the police also admitted, but the medical staff and police officers were very puzzled as to why Yang Yunzhong had no reaction when he was injected with potassium chloride.

You know, when high concentrations of potassium ions are injected into blood vessels, the pain is unbearable.

The patient must have struggled and shouted, but Yang Yunzhong did not show any such behavior, and remained calm all the time.

It's not very scientific.

The police also took his blood and sent it to the criminal identification center to test whether there were any abnormal components in the blood.

After the patient dies, the red blood cells in the body begin to destroy.

Potassium in erythrocytes is released in large quantities outside the body after cell destruction, that is to say, after the patient dies, the blood potassium concentration in the patient's body rises quickly. The potassium concentration in red blood cells is 30 to 40 times that in plasma, and the blood potassium concentration tested after Yang Yunzhong lost his vital signs has lost its meaning.

However, the police detected an anesthetic component in the patient's body. The existence of this barbiturate drug that can act in an ultra-short period explained everyone's doubts.

The woman dressed as a nurse injected Yang Yunzhong with a potassium chloride solution mixed with this highly effective anesthetic called thiopental, or injected him with the anesthetic first and then injected potassium chloride. Fast forward into anesthesia and nothing happens.
