Chapter 182 Angel of Death: The Real Murderer Emerges

After returning to the bureau, Fang Rui convened a case analysis meeting.

Fang Rui analyzed: "This should not be a medical accident, but a murder. The hospital's medication process is very standardized, and it is unlikely to make such a low-level mistake as pouring insulin into an infusion bottle."

Xiao Zhang said: "So Consultant Lin guessed right, there is indeed a serial killer in the hospital. If it weren't for the patient's family making a big fuss, this matter would never have been discovered."

Lin Sen corrected dissatisfiedly: "Please change the word 'guess' to 'analyze', otherwise it seems that I am very unprofessional."

"..."

Fang Rui said, "I don't think Li Xiaolan is the murderer. The murderer can't be so stupid as to attack patients while she is on duty."

Xiao Zhang agreed, "And Li Xiaolan's psychological quality is very poor. Such a person can't become a serial killer."

Mu Mian said, "Insulin can be bought online and in pharmacies. It is difficult for us to identify the murderer through the source of the drug.

However, epinephrine is a controlled drug. If Yangyang's death is also related to this murderer, then she must have misappropriated other people's epinephrine. We follow this clue and maybe we can find the murderer."

Fang Rui agreed, "And Yangyang is hospitalized in the Department of Neurosurgery. His ward is on the sixth floor. If the murderer went to replace the drugs, he must have gone to the nurses' station there. We can Retrieve the surveillance footage to see if any nurses from other departments went to the nurses' station there on the day Yangyang died."

Fang Rui thought of the old grandmother of the Ye family, and he added: "Could the murderer have also been to the Ye family?"

Chen Xue said: "It's possible! Ye Yu said that her grandmother suddenly felt very cold that night. Could it be that the murderer gave her some medicine, which caused her to be like this? And the carbon monoxide poisoning was an accident, which just happened to cover up her crime. "

Mu Mian said: "No abnormalities were detected in the blood of the deceased. She died of carbon monoxide poisoning. But there is a problem with the light green tablet. Its composition is still being analyzed. We will discuss it when the results are out."

Fang Rui decided to investigate separately. Mu Mian and Chen Xue went to investigate the use of epinephrine in the hospital; Xiao Li and others went to check the surveillance.

Fang Rui and Xiao Zhang drove to Ye Jianmin's house. Ye Jianmin went out to do farm work, and only his daughter Ye Yu was at home.

Xiao Zhang asked, "Ye Yu, do you know the nurse sister who often comes to your house to treat your grandmother?"

Ye Yu looked at Fang Rui and Xiao Zhang, she thought for a while, and nodded, "Yes."

"Is it her?" Fang Rui showed Ye Yu a photo of Li Xiaolan.

"It's her."

"Are you sure?"

Ye Yu nodded.

At this time, Ye Jianmin came back. He was a little impatient to see the police again, "Comrade police, why are you here again?"

"Is the nurse who often comes to your house her?"

"No. She only came once. The one who often came later was another nurse. That nurse has bigger and rounder eyes, her eyes are very beautiful, it's not her!"

Li Xiaolan has single eyelids and puffy eyes, and her eyes are a little smaller than normal people.

Fang Rui showed Ye Jianmin all the photos of the neurology department, "Mr. Ye, can you recognize which nurse it is?"

Ye Jianmin looked at the photos carefully and immediately shook his head and said, "They all look the same, how can I recognize them. That nurse always wears a mask, and I can't remember her face, I just remember that she has big eyes. You ask my daughter, she must know her. She has a very good relationship with that nurse."

Hearing Ye Jianmin's words, Ye Yu looked down at her toes, and the whole person was panicked because her lie just now was exposed.

Xiao Zhang handed Ye Yu a chocolate, then squatted beside her and whispered, "Can you tell the police uncle who the nurse sister is? We have something urgent to find her. Here is a photo, can you help us identify her?"

Ye Yu did not take the chocolate and did not speak.

Ye Jianmin kicked her, "You are so dumb, tell me something quickly."

Fang Rui glared at him, "Why did you kick the child? You dare to commit domestic violence in front of the police?"

"Oh, I am just anxious. This child has a strange temper. If you don't beat her, she won't tell the truth."

Ye Yu still didn't say anything. After a few seconds, she stretched out her hand and pointed to the photo of one of the nurses.

The nurse was named Zhang Shan.

Xiao Zhang said, "Ye Yu, thank you."

On the way back, Fang Rui was driving. Xiao Zhang took the photo and analyzed, "It seems that Zhang Shan is very suspicious."

"It's not her."

"Boss, you mean, Ye Yu is lying to us."

"Ye Jianmin said that the nurse's eyes are bigger than Li Xiaolan's, but this nurse has single eyelids and her eyes are not big either. Ye Yu should have just pointed to a photo at random."

"No wonder she didn't want my chocolate. But why didn't she tell the truth? She didn't know why we were looking for that nurse."

"Maybe she knows. So she is protecting that nurse."

"Then do we still have to go back and interrogate Ye Yu?"

Fang Rui said, "She doesn't want to say, and it's useless for us to interrogate her."

Xiao Zhang suddenly had a guess: "Could it be that the nurse instigated Ye Yu to kill her grandmother by burning charcoal?"

"It's possible." Fang Rui remembered that when Ye Yu confessed to them, she deliberately mentioned that she opened the window and put a bowl of water, which shows that Ye Yu knew that burning charcoal would cause carbon monoxide poisoning.

Xiao Zhang was boredly flipping through the photos of the nurses. He joked: "Xiao Wang's girlfriend also has big eyes. Her eyes are the most beautiful among these people."

Fang Rui and Xiao Zhang suddenly fell silent.

Fang Rui said: "In order to avoid suspicion, don't let Xiao Wang participate in this case."

"But Chen Shu is such a good person, how could she be a perverted killer? She is usually very kind."

"She is a suspect now."

Mu Mian and Chen Xue asked the hospital staff, and Mu Mian found a loophole. Generally, during first aid, doctors use the dose of epinephrine according to the patient's condition, rather than using the entire bottle. That is to say, it is possible that a medicine was prescribed but only half was used, and the rest was disposed of as medical waste.

The murderer may have collected adrenaline in this way.

Xiao Li's investigation and monitoring have also made progress. There is a camera at the nurse station of the neurosurgery department.

The camera captured the day when Yangyang died at 12:31 p.m. A nurse entered the room where the medicines were stored when no one was around. After staying there for about two minutes, she walked out.

At this time, Yangyang's grandmother passed by the nurse's station carrying a thermos bucket. She grabbed the nurse who was about to leave and said something to her. The nurse smiled at her and answered her question.

At this time, the camera captured the nurse's face. Although she was wearing a mask, Xiao Li recognized her at a glance.

"How could it be her?" Xiao Li exclaimed.

Xiao Li ran to tell Fang Rui and the others the news.

"Team Fang, I found a suspect," Xiao Li reported, "The surveillance video showed that on the day Yangyang died, she went to the neurosurgery nurse station. But she is a nurse in the neurology department, how could she go to the sixth floor and talk to Yangyang's grandmother."

"Who is the suspect?"

"Chen Shu... Xiao Wang's girlfriend."
