Ch12 - Cardiovascular Ward 07

At 6 o’clock in the afternoon, the students ate their dinners individually and then came to the ward where Yue Xingwen was. They handed over the ‘homework’ that had been assigned to everyone back to Yue Xingwen’s hand.

Yue Xingwen carefully summarized the homework submitted by everyone and sorted out the experiences of the five deceased before they passed away. 

Bed no. 5, 55-year-old lady had a cheerful personality. Her son and daughter-in-law were teachers, and they came to the hospital yesterday afternoon to visit her. Originally, it was said that she would be discharged today and that the old lady was recovering well. After hearing that she passed away unexpectedly, her family members came to the hospital this morning and refused to accept this fact, they cried in the ward for a while and argued with the doctors for a while.

Yue Xingwen handed the information to Liu Zhaoqing, who frowned and said, “This old lady died unjustly. She could have been discharged from the hospital today, but she had a sudden heart attack last night, no wonder it was difficult for her family members to accept it.”

 

 

Yue Xingwen continued, “The family of the 80-year-old man was very calm, he himself was in critical condition and had been hospitalized six times. His family should have been mentally prepared and quickly accepted the fact that the old man had passed away and they had already claimed the body.”

“The 60-year-old lady originally had a schedule for surgery three days later. Unfortunately, she passed away before the surgery could be done.” Liu Zhaoqing asked, “What did her family say?” 

Yue Xingwen said, “Her family member was not here, and her body hadn’t been claimed yet. The remaining 70-year-old and 77-year-old men had already undergone surgery. Their family members should have a much harder time, having thought the operation was a success and the result was sudden death after the operation.”

 

Liu Zhaoqing sighed. “*sigh*. Sudden illness and death in the middle of the night is very common in the hospital. I have encountered this several times during my internship. However, if it’s true, as you say, that someone is secretly doing the murder, that’s a completely different story.”

Yue Xingwen nodded. “So, we have to find clues as soon as possible.”

At 7:30pm in the evening, most of the doctors had already left work, and the students began to pretend to be ill according to Yue Xingwen’s instructions.

 

First, Liu Xiaoxiao in bed no. 4 pressed the nurse call button, and when the nurse came to the bed, she curled up on the bed and rolled around while shouting, “My stomach feels terrible, maybe I ate something bad, it’s so painful…” The skinny female student’s forehead was in a cold sweat, and she looked pale as she pressed her stomach. The nurse was startled and rushed to find the doctor on duty.

The doctor had just walked into Liu Xiaoxiao’s ward when the male student from the Chemistry Department also began to pretend to be sick. The male student already looked sickly, shrinking on the bed while shivering and pressing on his heart. Zou Yuhang, who was in the same ward, rushed to the doctor’s office with a nervous face and said, “Doctor, doctor, the patient in my ward is having a heart attack, please go and see him quickly!”

The doctor, who had just eaten his dinner, was called away by him.

 

Then, Qin Lu also cooperated with the act, pretending to have a headache, calling away the last doctor on duty. 

The patient’s condition in the ward was issued frequently, and the three doctors were called away from their office. Yue Xingwen and Liu Zhaoqing had been walking near the doctor’s office, and when they saw that the doctors were all called away, Yue Xingwen immediately gestured towards Ke Shaobin in the distance.

Ke Shaobin understood and slipped into the doctor’s office under the cover of Yue Xingwen. He opened the doctor’s computer and started deciphering the password. Liu Zhaoqing and Yue Xingwen guarded the left and right corners of the corridor to prevent doctors or nurses from coming.

Ke Shaobin was sitting in front of the computer, his slender hands tapping the keyboard quickly, looking extremely serious.

Lines of complex code appeared on the computer’s screen, and a few moments later, Ke Shaobin successfully hacked into the system. He quickly lifted his right hand, placed his laptop next to the desktop and turned on the wireless data transmission. 

A blue [data transfer in progress……] read bar appeared on the computer’s screen.

We’re sorry for MTLers or people who like using reading mode, but our translations keep getting stolen by aggregators so we’re going to bring back the copy protection. If you need to MTL please retype the gibberish parts.

Seeing that the transmission reached 80%, there was a sudden sound of footsteps in the right corridor. Liu Zhaoqing saw a nurse pushing a treatment cart and hurriedly stepped forward to stop the other party as he smiled. “Hello sister, I want to ask something, do I still need an injection tonight? I’m patient Liu Zhaoqing from bed no. 16.”

The data transfer finally became 100%, Ke Shaobin immediately withdrew from the system, raised his right hand to retrieve the laptop into his palm, and quickly slipped out of the office, turning away with Yue Xingwen.

After seeing the two of them approaching, Liu Zhaoqing then smiled at the nurse and stepped out to the side and said, “Thank you beauty.”

 

The three of them walked down the corridor towards the wards, and when they passed the nurses’ station, they noticed an oversized trash can labeled ‘medical waste’ at the end of the walkway next to the nurses’ station. Yue Xingwen looked at Liu Zhaoqing and pointed to the trash can. “Senior brother, do you want to check it out? If my reasoning is true, the evidence that the murdered didn’t have time to deal with might be in the trash can.”

Liu Zhaoqing nodded his head, “En, let’s go.” 

The three people sneaked up next to the nurses’ station.

As the other students were still dragging the doctors and nurses in their acting, there was no one nearby. Ke Shaobin guarded the entrance to the passageway to cover while Yue Xingwen and Liu Shaoqing stole two pairs of medical gloves from the nurses’ station to put on. They went through the trash can to start looking for clues.

Gauze and syringes had little value for the inspection, the key was in the medicine bottles.

Yue Xingwen rummaged through all the medicine bottles and infusion bags, while Liu Zhaoqing double-checked them carefully. “Saline, glucose, antihypertensive drugs, blood transfusion… There is also adrenaline, which should have been used when resuscitating the patient…” He went through the medicine bottles he had turned up in order, then shook his head, “It’s all common drugs, nothing out of the ordinary.” 

Although it was a wasted effort, Yue Xingwen was not frustrated and said softly, “No traces were left here, which means the murderer did not change the medicine at the nurses’ station, and the possibility of the nurses committing the crime is relatively low, so we can further narrow down the scope of the search.”

The three of them returned to the ward and sat down. A few moments later a few more students knocked on the door.

You Xingwen said in a gentle tone, “Everyone is working hard, come in and find a place to sit down. Let’s have a meeting to discuss it first.”

Zou Yuhang quipped, “It has the feeling of a class meeting ah, and Xingwen is our temporary class monitor?” 

Yue Xingwen smiled at him and looked at Ke Shaobin, saying, “Open the information and see the doctors’ conclusion.”

Ke Shaobin raised his right hand and the computer icon in his hand turned into a slim laptop, the other students were envious of the Computer Department’s reward—— There is a smart robot and now a laptop, the Faculty of Computer Science is really rich ah!

Ke Shaobin opened the folder of patient information in his laptop and rotated the screen to show it to Yue Xingwen. Yue Xingwen quickly slid the mouse over the medical records that he had finished reading yesterday, and directly opened the new section of ‘Death Case Discussion’, and said to Liu Zhaoqing, “Senior brother, you’re more professional about this matter, you should take a look too.”

Liu Zhaoqing moved a stool to sit next to him, looked at the screen and said, “These are the analyses of death cases recorded after the doctors held a meeting in the afternoon. The cause of death for all five people is written as acute myocardial infarction. The case contains details of the time of death, resuscitation records, and judging from the resuscitation records, the doctors did try their best, but unfortunately none of them were saved.” 

Yue Xingwen tore a blank piece of paper from the dictionary and said while sorting out——

“The patient in bed no. 15 died at 1:10am early in the morning; Bed no. 24 died at 1:20am early in the morning; Bed no. 5 died at 3:30am early in the morning; Bed no. 50 died at 3:40am early in the morning; Bed no.33 died exactly at 5:00am.” He looked up at everyone, “Have you guys noticed any pattern yet?”

The crowd looked at each other for a while.

Zou Yuhang took the lead in raising his hand and said, “Is it the time of death?” 

Ke Shaobin analyzed, “These bed numbers sound pretty messy, but after Xingwen organized them according to the time of death. The patients’ deaths seem to be divided into three stages; Two died at 1:10am and 1:20am, two at 3:30am and 3:40am, and one at 5:00am?”

The other students suddenly realized, but then they showed a blank expression. “Is there anything strange about this?”

 

Yue Xingwen drew a circle on the paper with a pen and explained, “The murderer’s time of operation, and the path of movement.”

Hearing the word ‘murderer’, a group of students froze at the same time. Zhou Yuhang’s face was pale and his lip could not help but tremble, “Mur–murderer? You mean, these five patients were murdered?!” 

“That’s right. The additional question is asking us to find the real cause of death of the patients in the ward, and if their death was not man-made, then the answer to this question should be ‘acute myocardial infarction’.”  Yue Xingwen paused and raised his eyes to glance at the crowd, “Do you guys think that the 30 points additional question will be so easy and give us the points straight away?”

It was very easy for everyone to think of a heart disease patient dying because of an acute myocardial infarction. The doctors’ analysis of death was also written like this, and it was certainly not the correct answer.

“Personally, I believe that the five patients died by the hand of the same murderer.” Yue Xingwen turned his head to look at Liu Zhaoqing, “Senior brother, is there any medicine that can cause a sudden heart attack in a patient with heart disease?”

“Vasoconstricting drugs.” Once again, Liu Zhaoqing clenched his left hand into a fist lightly to represent the heart and gestured on it with his right hand to explain, “You can understand it this way, a patient with coronary heart disease has narrowed arteries on the surface of the heart and the river is congested. Doctors usually use medications that relax and soften the arteries to clear the river. But if you go the opposite and give them drugs that constrict the arteries,” His two fingers suddenly clamped together, and continued, “Won’t the already narrow arteries get clogged when they’re blocked by the drug?” 

With senior brother Liu’s explanation, coupled with his action gestures, it was easy to understand. Originally, the patients had vascular stenosis, and if they continued to use that kind of vasoconstricting drugs, it could easily trigger a blockage of their arteries, leaving the patient unaware and suddenly dying of myocardial infarction.

——All they had to do was to find this person, and that would be the answer to the additional question.

Ke Shaobin offered another guess and said, “Some highly toxic substances could also kill these people quickly, right? Suppose, if someone added poison to their medication, and this one shot could kill five people as well?”

Yue Xingwen nodded. “Indeed, we can’t rule out the possibility of poisoning.” 

Qu Weiwei’s face turned pale, she bit her lip and asked, “But, who would do that? What is the reason for doing this? What kind of deep hatred did the five patients have with the murderer?”

Zou Yuhang speculated and said, “Judging from the information we have compiled, the five patients don’t know each other at all, and the probability of offending the same murderer is very small, right? Could it be some perverted doctors at the hospital doing human experiments? The previous course <Escape From the Lab> were animals mutation caused by a drug problem in the laboratory.”

Yue Xingwen had also thought about this possibility, and after a moment of contemplation, he pointed out a suspicion, “The laboratory course is where the researchers experiment with antiviral drugs on the animals’ bodies. If this cardiovascular ward is also experimenting with new drugs, senior brother Liu should be able to find out that something is wrong from the cases, right?”

He looked at Liu Zhaoqing, who hurriedly opened the diagnosis and treatment records of several patients in the laptop, pointed the drugs on it and said, “I saw the diagnosis and treatment plan yesterday, and there was nothing wrong with it. The doctor prescribed the patients with the common clinical drugs for controlling coronary heart disease, and we just went through the trash cans and found no suspicious medicines, so it shouldn’t be doctors doing experiments.” 

Ke Shaobin said, “After several analyses, Xingwen’s deduction is the most reasonable—— there is a lurking murderer in the ward who was committing the crime. He secretly switched out the medicine or added a strong poison to it, killing five patients in a row.”

The students’ expressions turned ugly.

Was this exam really a reasoning to find the murderer during the day and the terrifying battle royale at night?

Everyone looked at Yue Xingwen, and Zou Yuhang said, “Xingwen, do you have any clue about the murderer?” 

Yue Xingwen cleared his throat and concluded, “Many serial killers and murderers will have common characteristics, such as long-haired women, young men, etc., which usually has to do with the murderer’s hatred value towards that type of people. In our case, the five deceased have different ages, different identities, different genders, but the common denominator is in their heart disease. The murderer should have some dissatisfaction with the heart disease patient.”

Zou Yuhang could not help but spit out, “Specializing in killing the heart disease patient? Wouldn’t that be difficult to reason about?”

 

Yue Xingwen said calmly, “It’s not very difficult. Because the murderer in this case is still around us, with a fixed range of suspects, we can use the elimination method and line to investigate one by one.”

Liu Zhaoqing quickly reacted, “That’s right! The times of death for the patients that died last night were 1:00am, 3:00am, and 5:00am. The doors to the ward were locked at night so that outsiders couldn’t enter, indicating that the murderer had been in the ward all night!” 

Yue Xingwen nodded his head, “Those who stayed in the ward last night, apart from the 10 of us and the 5 who had been murdered, and all the doctors, nurses on duty and the patients are suspects. Let’s look at the picture I drew first”

He picked up the paper he had just drawn for a long time and displayed it in front of everyone.

The students were surprised to find that he had drawn a strange circular trajectory on it.

Yue Xingwen said, “The time of death of the five patients were 1:10am and 1:20am; 3:30am and 3:40am; and lastly 5:00am, divided into three stages. The order in which the murderer killed from bed no. 15, to bed no. 24, and then to bed no. 5, to bed no. 50, and finally to bed no. 33. This was the route the murderer moved last night.” 

He used a pen to draw three arrows on the paper, representing the murderer’s movement trajectory in three times periods, followed closely by, “According to the graphical trajectory analysis and criminal psychology inference, the murderer, when committing a crime, will first pick someone close to himself which is convenient to start, and only after the crime is successful will he pick a hospital bed at a distance. Well, the murderer is most likely in——”

He drew three trajectories of movement at an intersection, circling the two wards located at the intersection and said, “Here.”

The students stared dumbfounded at Yue Xingwen.

After a moment, Liu Zhaoqing gave a thumbs up, “Detective Yue, it’s awesome ah!” 

Zou Yuhang was impressed by Yue Xingwen and said, “Brother, aren’t you from the Chinese Department? How come you still know about trajectory analysis?”

Yue Xingwen explained with a smile on his face, “I have a good friend in the Mathematics Department, and I learned this method of trajectory analysis from him. If he had taken this exam, he would have quickly found the connection between the time of death, the path of movement, and location of the murderer.

Everyone: “……”

Following a class monitor like Yue Xingwen, was everyone ready to lie down and win to get points?
