The nurse took Conan's possessed trio to the hospital's oncology department, where the crime occurred.

Dean Lu had already arrived here, and when he saw the nurse coming with three strangers, one of whom was still wearing a hospital gown, he immediately frowned.

Seeing this scene, Dr. Pan, Dean Lu's assistant, immediately stepped forward and asked, "Didn't you all let the patients go back to their respective wards, how did you bring them here?" ”

"Doctor Pan, these three are all sirs." The nurse quickly explained.

Ah Li and Qiu Junxuan immediately took out their police cards and spoke; "We're police officers, and we've heard that there are deaths here, so we're here to take a look and avoid people from ruining the scene."

"It turned out to be a sir!" Dr. Pan nodded, and then looked at Ho Ka-fai, who was wearing a hospital gown.

"I'm also a police officer, but my police ID is in the ward." He Jiahui hurriedly explained.

"I remember, you are the sir who was injured at work, and your commander still asked me to take care of you!"

The doctor nodded, and then walked over to Dean Lu to report a few words.

"Invite a few sirs to come over!" Dean Lu spoke.

Hearing that the police were coming, Dean Lu immediately decided to hand over the scene to the police.

Conan's possessed trio was brought to the door of the oncology department, and Ah Li took the initiative to come forward to greet him: "Dean Lu, we met again, I don't know if you remember me, my name is Yu Xueli, and my father is Yu Shitang." ”

"I remember, you are Mr. Yu's son-in-law, what a talent!" Dean Lu said, but there was a hint of surprise in his eyes.

It is really rare for the son of a rich man not to go back to inherit the family business, but to become a policeman.

After greeting him, Dean Lu briefly introduced the case: "The deceased is Liu Guoqiang, a doctor from the oncology department of our hospital, who was on night duty last night. This morning, when it was time to shift his shift, we found him dead in the break room, so we immediately called the police. ”

"Dean Lu, can we go to the scene and have a look?" Ali asked.

"Yes, the break room is inside." Dean Lu pointed to the transparent glass door of the office area, and then said: "After the body was found, I asked everyone in the oncology department to withdraw, and the things inside were not touched, and the scene was well preserved. ”

Ali nodded, and was about to push the door, but the door didn't move.

Dean Lu immediately explained: "The management of our hospital is relatively strict, this is the office area of doctors and nurses, in order to prevent idle people and other unauthorized entry, so we have set up an access control card, and our staff need to swipe the card to enter." ”

Dean Lu said, and made a look with the assistant, who immediately took out his identity card and swiped it at the emotional device at the door before opening the door.

"Do you have shoe covers and gloves?" He Jiahui asked.

"Yes, I'll send someone to bring it right away." Dean Lu replied.

In places like hospitals, based on the need to prevent infection, not to mention shoe covers and gloves, even biochemical-grade protective clothing is available.

After putting on the shoe covers, Conan walked into the doctor's office with the trio, which is a common office area with many desks and computers, where the doctor usually writes medical records.

Dean Lu's assistant, Dr. Pan, said: "There is the rest room, and in the innermost, the men's and women's lounges are separated, and next to them are the men's and women's locker rooms.

Next to the changing room is the pantry, which usually stores some snacks, and on the very edge is a utility room where you can put some things that you don't usually need. Dr. Liu Guoqiang was found dead in the men's lounge. ”

He Jiahui looked at the layout of the scene, this row of rooms is in the innermost part of the office, separated by a corridor in the middle, and he can't see the situation of the various rooms in the corridor when he sits in the office.

"Doctor Pan, Dean Lu just introduced that the deceased was on the night shift last night, can he rest during the night shift?" He Jiahui asked.

Dr. Pan immediately explained: "Yes, during the night shift, if there is nothing in the ward, the doctor can go to the rest room to rest, of course, if there is an emergency, he must get up immediately.

In places like the oncology department, most of the patients are post-chemotherapy, their vital signs are relatively stable, the patients also have to sleep at night, and they will not be treated at night, as long as there are no critically ill patients, the work of the night shift is relatively easy. ”

While talking, several people came to the door of the men's lounge.

It was a small room, with a table, a chair, and two beds, and the room had no windows, only a central air conditioning outlet, and the deceased was lying on one of the beds.

The deceased was still wearing a white lab coat and the shoes on his feet had not been removed, and it seemed that he did not intend to rest for a long time, but probably just wanted to squint for a while.

"There are no obvious scars on the surface, and there is no residue at the corners of the mouth, it should not be poisoning, but more like sudden death, and the specific words have to wait for a forensic autopsy to give the result."

He Jiahui paused, and then explained to Ah Li and Qiu Junxuan:

"In general, people who die suddenly will suffer from certain diseases, such as cardiovascular and cerebrovascular diseases, respiratory diseases, central nervous system diseases, digestive system diseases, and so on."

"This sir is right, but Dr. Liu Guoqiang is in the prime of life, and our hospital will also organize regular physical examinations for employees, and Dr. Liu's body has always been healthy, and there are no of the above diseases, so we have doubts about the cause of Dr. Liu's death, so we immediately called the police." Dr. Poon explained.

He Jiahui pondered for a moment and said: "If it is sudden death caused by external factors, the most likely way is to inject substances harmful to the body, which will cause diseases of the cardiovascular and cerebrovascular system, respiratory system or central nervous system, resulting in death. ”

He Jiahui walked to the corpse as he spoke, and began to carefully observe the exposed skin of the corpse, and sure enough, a small pinhole was found in the position of the neck.

"Looks like this is a homicide!" He Jiahui immediately made a judgment.

At this moment, there was a sound of footsteps outside, and then a familiar voice sounded:

"I'm Chief Inspector Wong Kai-chie of the Regional Crime Unit of Hong Kong Island!"

Hearing this voice, the trio of Conan and his possession glanced at each other, and the three of them remembered that this time the location of the crime was on Huang Qiqi's territory again.

The royal praise has also arrived.

After a while, Huang Qiqi walked over and immediately saw Conan's possessed trio.

"Sir Huang, it's early!" He Jiahui greeted with a smile.

"Why are you three again!" Huang Qiqi grinned and said with an unhappy face: "Every time I meet the three of you, it's not a good thing, there must be another homicide!" ”

"Sir Huang, look at what you said, I didn't help you solve the case once!" He Jiahui opened his mouth to respond.

Huang Qiqi also noticed the hospital gown on He Jiahui's body, and immediately asked, "Why are you wearing this?" Sick and hospitalized? This hospital is also unlucky, it accepted you as a patient, and the doctor died as a result! ”

The two are also acquaintances, and Huang Qiqi directly ridiculed.

He Jiahui explained: "I am not sick, I was injured when I caught the thief. ”

"Where's the injury? Is it serious? Huang Qiqi asked with a concerned face, and there was a trace of anxiety in his eyes.

"Broken ribs." Ho Ka Fai replied.

"It's okay if you don't hurt your brain, and you won't delay solving the case." Huang Qiqi laughed again.

He Jiahui shook his head a little helplessly, and said secretly in his heart: "Huang Qiqi this guy, this is another want to pick up ready-made!" ”

Sure enough, Huang Qiqi asked directly: "You arrived before me, what did you find?" ”

"I found a pinhole in the neck of the deceased, indicating that the deceased should belong to him." Ho Ka-fai did not hide his findings either.

"There is a pinhole in the neck, is he killed?" Huang Qiqi began to raise the bar very cooperatively.

"If you get an injection, will you hit your neck?" He Jiahui asked rhetorically.

Huang Qiqi pondered, it was really like that, it was not a cat or a dog, how could there be a needle in the neck when the needle was given, and the needle hole in the neck of the deceased must have been left by the murderer when he committed the crime.

He Jiahui continued to ask: "Sir Huang, is the forensic doctor here?" ”

"Here, just outside." Huang Qiqi nodded.

"Let the medical examiner come in and work. First of all, the time of death of the deceased is determined, and then the deceased's blood is drawn and the deceased's blood sample is taken back for analysis. ”

Ho Ka-fai was worried that Huang Qiqi would not understand, so he went on to explain;

"I judged that the deceased was injected with some kind of toxic substance, which caused sudden death, in this case, there must be residues of this substance in his blood, and the cause of death of the deceased can be quickly determined through a blood test!"

Huang Qiqi nodded: "Okay, I'll arrange it right away!" ”

Not far away, Dean Lu looked at this scene with some confusion.

"What is the origin of this sir? Surely he is not a senior officer at such a young age! Huang Qiqi is the chief inspector of the serious crime team, why do you want to listen to his command? ”

The forensic doctor walked in and started working, while He Jiahui came to Dean Lu and whispered: "Dean Lu, if Dr. Liu Guoqiang died by him, the murderer is likely to be an internal member of the hospital, so please be mentally prepared!" ”

"You're saying it was our colleague who killed Dr. Liu? How is this possible! We're all doctors and nurses! ”

Dean Lu said with some incredulity, in his opinion, doctors and nurses are both professions that save people, how can they kill people?

He Jiahui explained: "The scene of the crime is a lounge, in the office area of the medical staff, I noticed that to enter this area, you must swipe the access control card, and the access card is only available to the internal staff of your hospital, which means that the murderer who killed Dr. Liu is most likely the internal personnel of the hospital." ”

After listening to He Jiahui's analysis, although Dean Lu didn't like it very much, he still accepted the reality and nodded.

In the end, he is a well-known doctor, he has seen a lot of life and death on weekdays, and he can bear things in his heart, so even if he learned that the murderer was his own person, Dean Lu's expression was still calm and did not change.

He Jiahui continued to ask: "Dean Lu, I want to ask, can your access card record the information of the person who swiped the card and the time of swiping the card?" If we can, this will help us narrow down the suspects. ”

"I really don't know about this, I need to ask the security department." Dean Lu said, turning his head to look at the assistant: "Doctor Pan, go and ask!" ”

"Okay, I'll call the head of security right away." Dr. Pan said, pulling out his phone.

After a few moments, Dr. Pan ended the call and spoke; "Sir, I'm very sorry, our access control system currently only has the function of identifying the access card, and it cannot record the person who swiped the card and the time of swiping the card."

He Jiahui nodded disappointedly, it seems that this access control system only has the simplest chip recognition function, as long as the chip in the identity card is read, the access control will open the door.

He Jiahui looked at the surrounding ceiling again, and then asked, "There should be no monitoring installed in the doctor's office, right?" ”

"The monitoring in our hospital is mainly installed in the common area where patients can move around, and there is no monitoring in the doctor's office. However, in the corridor outside, there is a surveillance. Dr. Pan replied.

"Can you see who has been in and out of the doctor's office?" He Jiahui asked again.

"I don't know much about this, I'll have to go to the monitoring room to check it out." Dr. Pan replied.

At this time, the medical examiner also completed the measurement of the deceased's liver temperature.

"By measuring the liver temperature of the deceased, it was preliminarily determined that the time of death of the deceased was between one and two o'clock in the morning." The medical examiner spoke.

The lounge is a confined space, which is always at a constant temperature, and the time from the death of the deceased is relatively short, and the estimated time of death is more accurate.

Huang Qiqi also came over and asked, "How is it, have you found a new clue?" ”

"Huang sir, the time of death of the deceased has been determined, it is between one and two o'clock in the morning, during this time period, most people are asleep, and there are definitely not many people who are still active outside."

He Jiahui pointed to the corridor, and then said: "There is a camera in the corridor outside, which should be able to capture who has entered this doctor's office, you send someone to check the surveillance last night, who has entered and exited here."

In addition, we have to ask the other people who worked the night shift here yesterday, Dr. Pan, who else was on duty in the oncology department last night, apart from the dead Dr. Liu? ”

Ho Ka Fai turned his head to look at Dr. Pan.

Dr. Pan immediately replied, "The manpower arranged at night is relatively small, and the night shift in the oncology department is not busy, so only one doctor and two nurses are arranged to be on the night shift." ”

"The night doctor is the deceased Liu Guoqiang, which means that there were two nurses here last night. Are the two nurses still in the hospital? He Jiahui asked.

"Yes. Because we found out that Dr. Liu was dead when we were on duty in the morning, the two nurses on duty last night had not left. Dr. Pan replied.

"Then please Dr. Pan, prepare a room for us, and we need to record a record for the two nurses. Also, I need information about these two nurses. He Jiahui said.

"Okay, I'll arrange it right away." Dr. Pan nodded, took out his mobile phone to check the night shift schedule, and spoke; "It was Zhou Yuting and Deng Qiaomei who were on the night shift last night, and I immediately asked the personnel department to send their materials over."

Thank you for subscribing. I went to Qinghai a few days ago, and I sent all the manuscripts during the period. Writing this type, I really panicked if I didn't save the manuscript, because when I write a case, I will always find that the logic is incoherent somewhere in front of it, and it is best to write a whole case and then send it out, so that there will be no problem logically. The number of words in the update is not much, and it is also because I want to save more manuscripts in the past few days, as long as I set aside a manuscript of the whole case. Thank you for your understanding.
