The hospital found a room to serve as a makeshift interrogation room for the police.

The information of the two night nurses was also sent to He Jiahui.

The first nurse was named Zhou Yuting, thirty-five, married, with no children, and had been working in this hospital for eleven years.

Another nurse, Deng Qiaomei, is 30 years old and unmarried, who came to the hospital three years ago.

Zhou Yuting was the first to be brought to He Jiahui, she was not tall, slightly fat, and her appearance was very ordinary, basically the kind of middle-aged woman who was completely inconspicuous in the crowd.

"Ms. Zhou, you worked the night shift with the deceased Dr. Liu last night, when was the last time you saw him?" He Jiahui asked.

Zhou Yuting thought for a while and replied: "Our nurses spend most of their time at the nurses' station, and at nine o'clock last night, when I came to take over the shift, I met Dr. Liu, and then he went back to the office, and I stayed at the nurse's station outside the ward. ”

"Haven't you ever been back to the office?" He Jiahui asked.

"Yes, I went back to the office three times during the night shift yesterday, about 1 a.m., 4 a.m., and 6 a.m., when I went to the pantry to get something to eat.

But when I went back, I didn't see Dr. Liu in the office, and I think he must have gone to the lounge to rest. It was normal for doctors to take a break during the night shift, and I didn't pay much attention to it at the time.

Until the shift this morning, Dr. Liu did not show up, and someone went to the break room to look for Dr. Liu and found him dead. Zhou Yuting replied.

Since there is no monitoring in the office, it cannot be proved that what Zhou Yuting said is true.

So He Jiahui opened his mouth to confirm: "Ms. Zhou, that means that every time you go back to the office, you are alone, right?" ”

"No, the first time I went back to the office, Dr. Cai was still there, and I said hello to him!" Zhou Yuting replied.

"Dr. Cai? Where did Dr. Cai come from? He Jiahui said secretly in his heart, and then asked, "Who are you talking about Dr. Cai?" ”

"It's Dr. Chua Shude, and he's also a doctor in our oncology department." Zhou Yuting replied.

"Did this Dr. Cai Shude also work the night shift last night? However, Dr. Poon told me that there was only one doctor assigned to the night shift in the oncology department. He Jiahui asked.

"That's right, it was indeed Dr. Liu who worked the night shift yesterday, and Dr. Cai stayed because he needed to work overtime, and he still had several medical records to write." Zhou Yuting replied.

"Is Dr. Cai still in the hospital?" He Jiahui immediately asked.

"After Dr. Cai finished writing the medical records, he should have left! He greeted us when we passed by the nurses' station, and I think it was about 3 o'clock in the morning. Zhou Yuting replied.

"The time of death of the deceased was between 1 and 2 a.m., and this Dr. Cai did not leave until 3 o'clock, so he had every time to commit the crime."

Thinking of this, He Jiahui immediately said to Huang Qiqi next to him; "Sir Huang, please send someone to find this Cai Shude."

Huang Qiqi immediately ordered his subordinates to find someone. Ho Ka-fai continued to ask, "Ms. Zhou, how was the deceased Dr. Liu's usual interpersonal relationship?" Did he ever have a feud with a colleague or any kind of conflict? ”

"Dr. Liu's popularity is okay, and I haven't heard of him having conflicts with other colleagues. However, she seems to have a very good relationship with Deng Qiaomei, and she can often see the two of them chatting together. Zhou Yuting said.

"Deng Qiaomei? It's the nurse who was on duty with you yesterday, right? He Jiahui nodded silently.

……

Next, another nurse, Deng Qiaomei, was also called in for questioning.

Deng Qiaomei is also not tall, but her figure is very slender, and she looks very petite. Compared with Zhou Yuting, Deng Qiaomei is obviously much more delicate, and she wears heavy makeup.

Women, as long as they can wear makeup, they will not be too ugly, so on the surface, Deng Qiaomei's image is better, even if she is wearing a nurse's uniform, she can feel that she is a person who loves to dress up.

"Ms. Deng, you worked the night shift with the deceased Dr. Liu last night, when was the last time you saw him?" Ho Ka Fai is still the same problem.

"The last time I saw Dr. Lau was about 12 o'clock in the evening. I went back to the pantry to drink water, and Dr. Liu was there, and he kept yawning and looked sleepy, so I asked him to go to the lounge to sleep for a while, and he agreed, and I never saw him again. Deng Qiaomei replied.

"The time of the deceased's death was between one o'clock in the morning and two o'clock in the morning, and Deng Qiaomei had seen the deceased at twelve o'clock, which means that the murderer's time of committing the crime should be between twelve o'clock and two o'clock in the morning."

Thinking of this, Ho Ka Fai then asked, "When you last saw Dr. Liu, was there anyone else in the office besides you?" ”

"Yes, Dr. Chua was there as well. He was in his position at the time, so he should be working overtime to write medical records! Deng Qiaomei replied.

"Ms. Deng, how was the relationship between the deceased Dr. Liu? Did he ever have a feud with a colleague or any kind of conflict? Ho Ka Fai asked the same question again.

"If you want to talk about conflicts, Dr. Liu once had a conflict with a doctor named Sun Ka-shing because of the allocation of funds for scientific research projects, but Sun Ka-shing left our hospital half a year ago and heard that he had emigrated to the UK." Deng Qiaomei replied.

In the UK, even if there is a motive for committing a crime, there is no possibility of committing a crime.

So Ho Ka-fai then asked, "Ms. Deng, how is your relationship with Dr. Liu?" ”

"I'm just a normal colleague with him." Deng Qiaomei hurriedly said, but her eyes flickered a little.

He Jiahui was keenly aware of this, and Deng Qiaomei's micro-expression had betrayed her.

And the nurse Zhou Yuting also said before that Deng Qiaomei had a very good relationship with the deceased, and at this time, Deng Qiaomei's performance was obviously deliberately concealed.

However, He Jiahui did not debunk Deng Qiaomei, he still has too few clues now, and he still needs more information.

……

After finishing the questioning of the two nurses, Huang Qiqi's subordinates also knocked on the door and walked in, leaned into the ears of the two and said, "I have contacted that Dr. Cai Shude, he is on his way, and he will arrive in half an hour." ”

A moment later, Huang Qiqi's subordinates who went to see the surveillance video also came back to report the situation.

"Sir Huang, I have checked the surveillance video on the night of the crime, and the surveillance video can capture the situation at the door of the doctor's office. According to surveillance footage, only four people have been in and out of the doctor's office since 10 p.m. last night.

They are the deceased Liu Guoqiang, the night nurse Zhou Yuting, the night nurse Deng Qiaomei, and another oncologist, Cai Shude. Among them, the deceased Liu Guoqiang went to the ward at half past eleven to patrol the night, and then returned to the office, and never came out again.

Zhou Yuting, a nurse on the night shift, returned to the office at 1 a.m., 4 a.m., and 6 a.m. respectively, and stayed for about 20 minutes the first time, and then stayed for about half an hour twice. The rest of the time, I stayed at the nurse's station in the ward.

Deng Qiaomei, a nurse on the night shift, returned to the office at 12 o'clock at night and stayed for about half an hour. At 1:40 a.m., Deng Qiaomei returned to the office for the second time and stayed for about 20 minutes. At five o'clock in the morning, Deng Qiaomei returned to the office for the third time and stayed for half an hour again.

Doctor Cai Shude stayed in the office after 10 p.m., left the office at about 12:30 p.m., returned 10 minutes later, left the office again at 2 a.m., returned 10 minutes later, and left the office at 3 a.m. and never returned. ”

"The monitoring is consistent with the descriptions of the two nurses. In other words, all three people were in and out of the office during the time of the deceased's death. It seems that the murderer is among these three people. He Jiahui said.

At this time, Huang Qiqi's subordinates came over again to report: "Huang sir, the doctor named Cai Shude has arrived. ”

"Then ask Dr. Cai to come and assist in the investigation!" Huang Qiqi said immediately.

Cai Shude was taken to the room, and He Jiahui still had the same old question: "Mr. Cai, may I ask when was the last time you saw the deceased?" ”

"It was last night, I can't remember exactly what time it was." Cai Shude lifted the glasses on his nose and continued; "Yesterday I was on the afternoon shift, from 1 pm to 9 pm, and I met Dr. Liu when the shift was handed over at 9:20.

But because I had a few medical record reports that had not been completed, I stayed in the office after work in the evening to work overtime, and it was common for me to work overtime to write medical records.

Although I was in the office at the time, when writing medical records, I was usually more engaged, and medical records could not be wrong, so I didn't pay attention to other people and things at the time, and even if someone walked by me, I wouldn't pay attention.

When I finished writing my medical records, I realized that I was the only one in the office, so I packed up and went home, it was about 3 a.m., and I was saying hello to the night nurse when I passed by the nurse's station. ”

"Have you ever left the office?" He Jiahui asked.

"I remember going to the bathroom twice, and then going straight back to the office." Cai Shude replied.

The content of Cai Shude's narration is also consistent with the surveillance.

Ho Ka Fai asked again: "Dr. Cai, how was the relationship between the deceased Dr. Liu usually?" Did he ever have a feud with a colleague or any kind of conflict? ”

Cai Shude replied: "In work, it is inevitable that there will be disagreements, and for the same patient, different doctors will give different treatment plans, and sometimes there will be some fierce debates over whose plan to adopt.

It is also impossible for two doctors to have no disagreement at all. But we are all professionals, and we all understand that medicine is actually science, and when we encounter disagreements, we will talk about things on the facts, and it is impossible to count differences in work as personal grievances.

So I think this is at most a case discussion, not a conflict between colleagues, let alone a feud. As for Dr. Liu's interpersonal relationships......"

Cai Shude put on an expression of wanting to speak at this time.

"Doctor Cai, if you have something to say, don't worry, we police officers are also professional and will keep the witnesses confidential." He Jiahui said.

"Hey......" Cai Shude sighed and said helplessly: "I don't like to chew my tongue behind my back, and I won't reveal their privacy in private, but since I am involved in the case, I will definitely cooperate with the police."

As far as I know, Dr. Liu and Nurse Tang are relatively close, and the friendship between the two of them has surpassed that of colleagues or friends. “

"The Nurse Deng in your mouth is Ms. Deng Qiaomei, right? Do you mean that there was an improper relationship between Dr. Liu and Nurse Tang? He Jiahui asked immediately.

Cai Shude nodded: "There is indeed a super-friendly intimacy between them. This doctor and nurse work together all day, and often work night shifts together, and it is not very strange that they are bored at night, and they spark each other.

But Dr. Liu has a girlfriend, and they have already met their parents, and to the point of talking about marriage, Dr. Liu also plans to buy a house and get married in the near future.

However, Dr. Liu's girlfriend probably didn't know about him and Nurse Tang. Dr. Liu's relationship with his girlfriend should still be very good, the day before yesterday, her girlfriend's birthday was celebrated, and the two celebrated together! ”

"Mr. Cai still knows a lot about Dr. Liu's private life!" He Jiahui said very casually, in fact, he was tempting.

Cai Shude can become a doctor, and he is naturally a smart person, he sensed He Jiahui's intentions, and immediately explained:

"I know this because Dr. Liu came to me a few days ago when he was planning to buy a house and get married. The apartment I have now is less than half an hour away from the hospital, so it is easy to commute to work.

So Dr. Liu asked me about the environment and property there, and he also wanted to buy a house in that area, and I only found out at that time that he planned to buy a house and marry his girlfriend. ”

As for him celebrating his girlfriend's birthday, I saw it on social software, and the news feed he posted himself, as long as he followed his friends, he could see it. I also gave it a thumbs up. ”

Cai Shude said and took out his mobile phone, found the news message, and handed it to He Jiahui: "Sir, look, this is the message sent by Dr. Liu at that time." ”

He Jiahui took the mobile phone and looked at it, and sure enough, it was a photo of the deceased Liu Guoqiang celebrating his girlfriend's birthday, and the date was the night before yesterday.

"Have you contacted Liu Guoqiang's girlfriend?" He Jiahui opened his mouth and asked Huang Qiqi beside him.

Huang Qiqi shook his head: "At present, only the immediate family of the deceased, that is, his parents, have been notified. ”

Cai Shude, who was opposite, opened his mouth and said: "Sir, it's useless for you to inform her girlfriend, her girlfriend has gone abroad, and she is not in Xiangjiang." ”

"You know that, too?" Huang Qiqi asked.

"It's also Dr. Liu's own news, you pull the screen, there is a picture of Dr. Liu sending his girlfriend to the airport." Cai Shude said.

He Jiahui immediately looked at the back of a few updates, and indeed found a photo of the airport, and the text on it was also to send his girlfriend to the airport.

"Social software is really powerful these days, what do you want to know, look at what the other party's news has posted, faster than our police investigation." He Jiahui said secretly in his heart.

Then Ho Ka Fai then asked: "Mr. Cai, how did you know that Dr. Liu and Nurse Deng had an abnormal relationship between men and women?" Shouldn't it be looking at social software, right? I don't think anyone would make a fuss about this kind of thing. ”

Zhou Yuting only knew that the two were relatively close, but Cai Shude knew that the two had an improper relationship between men and women, which was indeed doubtful.

Cai Shude opened his mouth and replied: "I only learned about this matter recently. On weekdays, Dr. Liu and Nurse Deng are just close to each other and often chat together, so I thought they just had a common language.

Not long ago, Dr. Liu planned to buy a house and marry his girlfriend, and was found out by Nurse Deng. Nurse Deng had a big fight with Dr. Liu in the warehouse next to the pantry.

Dr. Lau said that he was going to marry his girlfriend and planned to end the relationship with Nurse Tang, but Nurse Tang disagreed and blamed Dr. Lau for marrying his girlfriend.

I also happened to go over to get something, and I heard it inadvertently, but after all, this is personal privacy, and it is not convenient for me to snoop, so I left quickly, they should not know that I have been there.

According to my estimate, it should be Nurse Deng who was unwilling to learn that Dr. Liu was getting married! Dr. Liu is a talent, and his income as a doctor is also high, but he is a golden beetle son-in-law in the eyes of many people.

Nurse Deng knew that Dr. Liu had a girlfriend and was willing to be with him, just hoping to be able to 'turn positive', but now that Dr. Liu is getting married, Nurse Deng has no hope of becoming a regular and is naturally unhappy. ”

"Dr. Cai, you know Nurse Deng very well!" He Jiahui said with a smile.

"It's not that I know Nurse Deng, it's because I'm also a doctor, and I've seen a lot of things like this." Cai Shude shook his head with a wry smile, and continued: "Many of the patients in our oncology department are elderly, so there are very few peachy incidents.

In some departments with a large number of young patients, patients often confess to their doctors. In particular, the kind of doctor who is about forty years old and not yet married, is the most popular.

Doctors at this age are in the prime of life, and their income has entered a relatively lucrative stage, so even if they are Hong Kong sisters, they can marry home. If I were Nurse Deng and had the opportunity to marry a young and promising doctor, I would definitely fight for it. ”

Cai Shude's statement that a doctor can marry a Hong Kong sister is not an exaggeration, and there are even many cases in reality. For example, the "White Lady" Ms. Zhao Yazhi, her first husband was a doctor ten years older than her.

It often appears in Hong Kong dramas that parents hope that their children will grow up to be doctors and lawyers, because these two professions are really profitable in Xiangjiang.

Being a lawyer also requires a certain amount of connections, and lawyers without connections, that is, middle-class income, do not make a lot of money.

But doctors are different, doctors rely more on technology, as long as the technology is excellent, even if you have a very bad temper and a very poor interpersonal relationship, at most others will hurt you behind your back, but it will not affect your money.

The reason is very simple, when you need a doctor to save your life, will you choose a doctor with extensive connections, high moral character, and a particularly sweet mouth? Or will you choose a highly skilled doctor?

Connections, medical ethics, and service attitude, no matter how perfect they are, they can't cure the disease. In the field of doctors, if you want to make a lot of money, any medical ethics and attitude are only auxiliaries, and technology is the core competitiveness.

……

After ending the questioning of Cai Shude and inviting him out of the room, Huang Qiqi took the initiative to say:

"At present, it seems that Deng Qiaomei's crime is the most suspected. She had an improper relationship with the deceased, but deliberately concealed it, saying that the two were just ordinary colleagues, and it was probably because she was afraid that if she talked too much, the police would find out about her.

And she also has a motive to kill. Liu Guoqiang wants to marry his girlfriend and doesn't want to continue his relationship with her, so it is reasonable for her to be angry with Liu Guoqiang and kill him. ”

This time, Ho Ka-fai did not refute, judging from the clues currently in hand, Wong's analysis is correct.

At this time, Huang Qiqi's mobile phone text message suddenly rang, and the forensic doctor completed the blood test of the deceased and sent a message.

"The medical examiner conducted an examination of the deceased's blood and found a relatively high residue of sedative, which should be enough to cause death. The forensic doctor preliminarily judged that the deceased should have been injected with a large amount of sedatives by the murderer, which affected the central system and caused respiratory failure and died. Huang Qiqi said.

"All those sedatives?" He Jiahui asked.

"I'll ask the medical examiner." Huang immediately sent a message to the medical examiner, and a moment later, the medical examiner replied with a message.

"There's midafile, promethazine, and chlorpromazine." Huang Qiqi replied.

He Jiahui thought for a moment and asked, "That's all?" Nothing else? ”

Huang Qiqi reconfirmed the message sent by the forensic doctor and replied, "No." ”

He Jiahui shook his head: "No, there should be more than that!" There is at least one tranquilizer. ”

"Why? You are not a murderer, how do you know how many tranquilizers the murderer used! Huang Qiqi asked.

He Jiahui explained: "The sedatives you just mentioned need to be injected, just imagine, if it were you, if the murderer injected something in the neck, would you immediately call for help?" What's more, it's still a hospital.

Even if there is an overdose of sedative, it takes a certain amount of time for the seizure to occur, which is enough time for the deceased to run to the nurse's station outside, right? If you're quicker, you might be able to run to the emergency room on your own!

But the deceased died in the end, which means that he did not go out to call for help, so the only possibility is that the deceased was not awake when the murderer injected the deceased with sedatives, and he was either unconscious or asleep.

There were no traces of a fight at the scene, and there were no external injuries on the deceased's head, so it was impossible for him to be knocked unconscious, so it means that the deceased was asleep at the time, and he slept very deadly, and he couldn't wake up even with a needle in his neck.

Normal sleep, it is impossible to be pricked by needles and not wake up, and the deceased is still wearing shoes, obviously wanting to take a little rest and not planning to go into a deep sleep.

Therefore, I judge that the deceased should have taken sleeping pills before his death, and these sedatives you just mentioned are not the main ingredients of sleeping pills. The deceased should also have at least one tranquilizer in his body that is often used as a sleeping pill. ”

"But the medical examiner didn't detect it." Huang Qiqi said.

"When the forensic doctor drew blood, five or six hours had passed since the incident, and it could not be ruled out that the sleeping pills had been metabolized, so they could not be detected." He Jiahui said.

"Talking is equal to saying nothing!" Huang Qiqi pursed his lips: "It's all metabolized, that is, it's gone, how can I check?" ”

"Isn't there any forensic evidence?" Ho Ka-fai continued; "Sleeping pills generally need to be taken orally, so the deceased must have eaten or drunk something last night, go and check the cups, food packaging and other things, maybe you can find the residue of sleeping pills!"
