Seeing that Ling Ruonan was very aggrieved and shed tears there, while Wu Yue lowered his head and looked dejected, Luo Ziling finally couldn't bear it.

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

"Mom, or, after dinner in a while, let's have a good chat," Luo Ziling softened, "Wu Yue and I will tell you everything, and you will make a decision after listening." What do you think needs to be remedied, you decide. ”

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

"Yes," Wu Yue nodded and walked out as well.

Luo Ziling and Ling Ruonan continued to be busy in the kitchen, but neither of them said anything, except for the sound of the range hood in the kitchen, there was only the sound of chopping vegetables and stir-frying, and the atmosphere was very dull, which made Ling Ruonan feel very depressed and made Luo Ziling feel very uncomfortable.

It's just that the mother and son don't know how to break this dullness.

When Luo Ziling and Ling Ruonan thought of their anger, there was chaos in the VIP ward of the high-ranking cadres of the Yanjing People's Hospital, which was about three kilometers away from where they lived.

Emergencies made everyone confused.

Yang Yunzhong, a VIP-level patient who has lived with them for nearly a month and whose injuries have stabilized, suddenly deteriorated, and the medical staff immediately put in the rescue, but in the end, the rescue was too late, and the line on the ECG monitor indicating the heartbeat was slowly straightened.

After more than an hour of resuscitation, the hospital finally declared the patient dead.

When Yang Yunzhong's condition deteriorated, the hospital immediately called the police, and the police rushed to the hospital as quickly as possible to control the floor where Yang Yunzhong was staying. Most of the leaders of the hospital also rushed to the ward in a very short time.

After Yang Yunzhong's death was announced, the doctor 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 leaders.

"The patient was injected with a large amount of potassium chloride, which led to cardiac arrest and death. "This is what the doctors involved in the rescue wrote on the case and the cause of the patient's death that they reported.

It was precisely because it was found that a high concentration of potassium chloride was artificially injected that the hospital called the police as soon as possible.

Before Yang Yunzhong was pronounced dead, the police who arrived at the scene discovered an abnormal situation.

A nurse in the ward was found unconscious in the dispensing room, stripped of her work clothes.

When the police discovered the situation, they immediately called up 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 over her face, and a hat on her head, she could not see anything unusual from the surveillance.

The nurse pushed a cart out of the dispensing room, and she went straight into the ward where Yang Yunzhong was staying.

There were bodyguards guarding the door of the ward where Yang Yunzhong lived, but they did not have any interrogation of 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.

There is no way to tell what to say without audio collection in a monitoring system.

The nurse pushed the dressing cart and left, walked to the other side of the room, disappeared from the surveillance range, but soon appeared in another surveillance.

After she walked to the ward next to the elevator, she looked back in the direction of the surveillance, and then put the dressing change cart at the door of the ward, and walked in the direction of the elevator. As soon as the elevator doors opened, she stepped inside.

The police continued to track down the surveillance inside the elevator and found that the nurse had not been seen since she went to the washing room in another ward.

Police officers immediately went to the washing room and found a set of nurses' overalls in the washing room, but no one was inside.

When the police inspected the washing room, they found that the bathroom was next door to the washing room.

After discovering this, 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 footage, the police finally found that the number of people entering and leaving the bathroom was different, and there were one more people leaving the bathroom than entering the bathroom.

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

After a rigorous comparison, the police zeroed in on a woman in a pink down jacket, a beanie hat on her head, and a mask over her face.

After the woman left the bathroom, she took the elevator down the stairs again.

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

After reviewing all the surveillance video in the hospital, the police still could not find any trace of the woman again.

The surveillance video of the nearby neighborhood was also called, and the police used a large number of personnel to check all the surveillance video in the nearby area, but still failed to find 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, it is a large dose of potassium chloride injected by someone outside dressed as a nurse on Yang Yunzhong's body, causing Yang Yunzhong to suffer cardiac arrest and die.

At the time of rescue, the medical staff also gave Yang Yunzhong electrolytes and a number of other biochemical tests.

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

Synchronously with hyperkalemia, there are also a number of index abnormalities.

Originally, the biochemical indicators in Yang Yunzhong were basically normal, and the abnormalities in the back should be the result of high blood potassium.

The police also recognized that a large amount of potassium chloride injections led to Yang Yunzhong's death, but the medical staff and police personnel were puzzled by why Yang Yunzhong did not react when he was injected with potassium chloride.

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

The patient must have struggled and shouted, but Yang Yunzhong did not show the slightest such performance, and he was very calm.

It's not very scientific.

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

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

Potassium in red blood cells is released in large quantities outside the body after cell destruction, that is, the concentration of potassium in the blood of the patient rises very quickly after the death of the patient. The potassium concentration in red blood cells is 30 to 40 times that of plasma, and the blood potassium concentration taken by Yang Yunzhong after losing his vital body has lost its meaning.

However, the police detected an anesthetic component in the patient's body, and the existence of barbiturates, which can work for an ultra-short time, explains the doubts in everyone's minds.

The woman who was dressed as a nurse injected Yang Yunzhong with a potassium chloride solution mixed with this highly effective anesthetic called sodium thiopental, or injected him with anesthetic first and then potassium chloride, so that Yang Yunzhong quickly fell into anesthesia and did not react.
