Escape From the Library

The principle of proximity is the murderer's thinking often mentioned in "Criminal Psychology". People can't help being nervous in unfamiliar environments and are prone to make mistakes, but they will be more confident in the environment they are familiar with and the people around them.

Therefore, serial murderers often choose people who are close to them and around them to attack first. After killing one or two people, the murderer will have a sense of accomplishment in killing people, and his courage will gradually increase, and the scope of the crime will also increase. Expand accordingly.

This is the basis for Yue Xingwen to judge the murderer's location.

He drew the distribution of all the wards in the ward on a piece of paper, so that the students could understand his thinking more intuitively.

-------Doctor Office Area---------

05/04/03--口口--48/49/50

08/07/06--口口--45/46/47

11/10/09--口口--42/43/44

14/13/12--口口--39/40/41

17/16/15--口口--36/37/38

20/19/18--口口--33/34/35

23/22/21--口口--30/31/32

26/25/24--口口--27/28/29

VIP ward---Koukou---VIP ward

--------Nurse Station------------

The dotted line part represents the corridor, and the road in the middle area is blocked.

The ward number starts from No. 3, goes from the upper left corner to No. 50 in the upper right corner in order.

越星文指着地图跟同学们解释道：“整个心血管病区是‘回’字形走廊结构，上方医生办公区，下方护士站。左、右下角是VIP病房，两边走廊各8个病房、24张床位。左边最上方3/4/5床，最下方24/25/26床；右边下方从27/28/29床开始，右上角48/49/50床结束。”

When everyone saw the distribution map of the ward drawn by him, they quickly took a blank piece of paper to copy a copy, just like taking notes in class, and marked their corresponding bed number and the location of the deceased.

Yue Xingwen also marked the locations of the five deceased with asterisks, saying: "The two patients who died at 1 am, beds 15 and 24, the beds are all close to the corridor, that is to say, the murderer gently opened the door in the middle of the night. , two steps forward, you can directly add vasoconstrictor drugs or toxins into the patient's syringe, which is very convenient to commit crimes."

Liu Zhaoqing finally understood: "The first time a murderer commits a crime, he will choose someone who is close to him. After killing someone, he can return to his ward as soon as possible to avoid being bumped by other patients or doctors and nurses. Then, leave The deceased's nearest...that is, the patients in the two wards of 18/19/20 and 21/22/23?"

Ke Shaobin took a closer look with his glasses, and suddenly realized: "The deceased in bed 15 was on his left when he went out; the deceased in bed 24 was on his right. The time for committing crimes back and forth will not exceed 10 minutes, which can also explain. There was only 10 minutes between the deaths of the two people? Because they were so close, it was convenient for the murderer to commit crimes?"

Yue Xingwen nodded: "That's right. There are doctors and nurses on duty in the ward at night. Once the patient is in trouble, the nurse station will call the police. The murderer must quickly inject the patient with dangerous drugs within 10 minutes and sneak back to the ward. Otherwise, the nurse station will call the police." After calling the police, the doctors will quickly rush to the scene for rescue, and it is easy to bump into the murderer in the corridor."

Since the murderer is next door, it will take a very short time to go out to kill and sneak back to the ward.The deceased was on his left and right, very close to him, and he could observe the rescue situation of the doctors and nurses at any time after killing someone.

Yue Xingwen continued to analyze: "After killing these two people, he became more courageous. Two hours later, when he committed the crime again at 3:5 in the morning, he chose a farther target. 50 beds and 5 beds, the distance The doctor's duty room is relatively close, and there happens to be a bathroom there, so he can pretend to go to the bathroom, kill 50 beds first, then kill [-] beds, and then quickly return to his ward."

"At 5 o'clock in the morning, when he committed the crime for the third time, he chose the farthest target. He even swaggered around in front of the nurse's station, touched the ward in the lower right corner from the corridor on the left, and killed patient No. 33."

Seeing that Yue Xingwen had completely drawn the murderer's moving route, the students all gave thumbs up: "Xingwen's reasoning, I think it is very logical!" "I also think that the murderer's crime is divided into three time periods, so it must It is to find the ones that are close first, and then kill the ones that are far away."

Remembering that the murderer had entered and exited his ward last night, and quietly killed the patient in the next bed, everyone's spine shuddered, and a layer of goosebumps fell off.

Liu Xiaoxiao shivered, gritted her teeth and asked, "Xingwen, are you sure the suspects are these patients? Doctors and nurses, are they also likely to commit crimes?"

Yue Xingwen said: "Of course. The principle of proximity does not apply to doctors and nurses. If the murderer in this case is a medical staff, they can enter and leave any ward at will. Even if they are seen by patients or colleagues, they will not arouse suspicion. No need Follow the rule of 'kill near first, then kill far away'. Medical staff can commit crimes randomly, and the time and path we analyzed are meaningless."

He opened the information of the medical staff in the ward and focused on last night's duty list: "This is the list of doctors and nurses on duty last night. Let's first recall your impressions of them and see if there is any doubt about their information." We cannot rule out the possibility of medical staff committing crimes that student Liu Xiaoxiao mentioned."

Yue Xingwen distributed the information of doctors and nurses, and asked everyone to look for clues carefully.

Liu Xiaoxiao took the information and looked it over, and said: "This is the sister nurse in our ward. She has a gentle personality. I heard her chatting with people yesterday. She is going to get married next week, and she sent invitations to her colleagues. The happy event is coming, she should Isn’t he the butcher who killed five people in a row?”

Qu Weiwei, who was in the same ward, added: "I noticed that the nurse was wearing a diamond necklace around her neck. She said it was a gift from her fiancé. The relationship between the two should be very good. Such a girl has no motive to kill suddenly."

Yue Xingwen nodded and looked at everyone: "Where are the other nurses?"

Zou Yuhang frowned and said, "This is the nurse in charge of our ward. She is a girl who just graduated. She is only in her 20s. She has a shy personality. When I asked her something yesterday, she blushed, and she didn't look like a murderer." ah?"

Ke Shaobin looked serious: "The third one is the nurse in charge of our ward. She quarreled with her husband. I heard her chatting with someone yesterday. She was obviously not in a good mood. I asked her a question, and she even got angry with me. A few words. She seems to have just returned to work after her maternity leave, and she looks anxious. But it's not to the extent of killing a patient to vent her anger, right?"

Liu Zhaoqing said: "She quarreled with her husband, and if she wanted to vent her anger and kill someone, she would kill her husband first."

Everyone: "..."

What the brother said was reasonable, her husband made her angry, she had no reason to go back to the hospital to kill patients, and even killed five in a row.

Yue Xingwen didn't suspect that it was a nurse who committed the crime. None of the three nurses had a motive for committing the crime. Besides, after changing the medicine, the nurses would habitually throw the medicine bottle in the trash can next to the nurse station for collecting medical waste. The bucket will be cleared every day, so there is no need to worry about being found evidence. He and Liu Zhaoqing rummaged through the trash can, but found no clues.

The reason why he analyzed and excluded them one by one was just to let the students recognize his inferences.Otherwise, if the final answer is wrong, the students will blame him for not analyzing well, and the monitor is not so easy to be.

Yue Xingwen looked at Liu Zhaoqing: "Brother, do you think there is anyone suspicious among the three doctors on duty?"

Liu Zhaoqing looked down at the names on the duty list, and dug out their information from the computer: "The doctor in charge Xiao Wen is smart and capable. He graduated with a Ph. Years of reading, writing papers, and training, finally became an attending doctor, and came to the ward to kill people? It can’t be so crazy, unless he is psychopathic.”

Yue Xingwen nodded: "Well, only antisocial personality disorder or psychopath can do such a thing."

Liu Zhaoqing touched his chin and continued to analyze the other two doctors on duty: "Doctor Ma Ping is 30 years old, a resident doctor, and his resume shows that he was transferred from another hospital. He has only worked here for a year, and he always feels that it is difficult to deal with patients in the ward. No idea; another Sun Liang is an intern, 25 years old, just graduated from graduate school, doesn’t seem to have any motivation?”

Yue Xingwen thought for a while, and finally came to a conclusion: "The three nurses can be ruled out with a high probability. The three on-duty doctors who stayed in the ward last night are waiting to be determined. The more suspicious ones are the two I just analyzed based on the path. patients in a ward."

There must always be a motive for killing, and you can't kill randomly in a bad mood.What's more, last night's murderer was quite well prepared. Obviously, he did not commit the crime impulsively, but planned it for a long time. The murderer also knew the relevant theoretical knowledge of cardiology.

Yue Xingwen picked out the patient data of the two wards and handed them to the students: "6 suspects, an 18-bed old lady who just finished surgery, is currently wearing an oxygen mask, is unconscious, and has difficulty in moving herself. The first one to rule out .”

Zou Yuhang added: "The two grandfathers on beds 22 and 23 live next door to us. They are both over 70 years old. One is a cement worker for a decoration company, and the other is a carpenter. , still chatting about their grandson’s exam results in the corridor, they seem honest and honest, so they probably don’t understand this kind of medical knowledge? I don’t think they are too suspicious.”

6 people ruled out 3, and the scope narrowed down again.

Yue Xingwen opened the information of the remaining three people: "Bed 19, a retired professor of medical school; Bed 20, engaged in pharmacy-related work in the hospital; Bed 21 was a medical representative. All three of them have received medical education, and they should know How to cause sudden death of myocardial infarction patients, all of them are between 50 and 60 years old, their condition is not serious, and they all have the conditions to commit the crime. The next step is to find the motive for the crime.”

Yue Xingwen couldn't understand why the murderer hated heart patients so much?

Just then, the door of the ward was suddenly pushed open.

Everyone turned their heads in unison, only to see Xiao Wen, the attending doctor in a white coat, walking in with no expression on his face. Seeing so many patients gathered in the ward, he raised his eyebrows in displeasure, and asked coldly: "What are you doing?" What?"

The students almost blurted out: We are having a class meeting.

Facing the doctor's cold gaze, everyone quickly lowered their heads.Ke Shaobin was quick to gain wisdom, closed the data in the laptop with one click, opened a movie that came with the computer, and said with a smile: "Doctor, everyone is too boring, let's watch a movie together." What he opened was a horror movie "The Grudge", in which a female ghost crawled out from the ground.

Doctor Xiao's face became even more ugly: "A group of heart patients gather here to watch ghost movies, do they think they live too long?"

Everyone: "..."

Doctor Xiao sternly said, "Not going back yet?!"

After being stared at coldly by the doctor, the students immediately dispersed and fled back to their wards.

Yue Xingwen and Liu Zhaoqing quickly sat down on the bed.Dr. Xiao came over, picked up the stethoscope and listened carefully to the heart rate of the two people, and said indifferently: "The diagnostic results of the coronary CT scans for the two of you have come out."

Liu Zhaoqing hurriedly asked: "Doctor Xiao, is it not serious?"

Dr. Xiao looked at him and said, "Liu Zhaoqing, your left anterior descending coronary artery has 80% stenosis." Then he took out another film and handed it to Yue Xingwen, saying, "Your left circumflex artery is 80% stenotic. , the condition is quite serious, and has reached the surgical standard. Fortunately, you are still young and have no other underlying diseases, and the prognosis is not bad if you undergo interventional surgery."

Yue Xingwen and Liu Zhaoqing looked at each other and blurted out: "Surgery?"

Dr. Xiao: "This is the informed consent form for the operation. Please read it first and ask the family members to sign it another day."

Yue Xingwen took the consent form and looked at the list of "dangerous situations" and "possible postoperative complications". The more he looked at it, the more his scalp became numb. He couldn't help but said, "Is it necessary to do it?"

Dr. Xiao responded indifferently: "80% stenosis can easily cause blood vessel blockage, it is best to operate as soon as possible."

After the doctor left, Yue Xingwen couldn't help pressing his temples with a headache: "You won't really send us to the operating room, will you? This course experience is too rich." He rarely gets sick, but this time he got a heart attack. Entering the hospital, encountering serial murders, and running for his life at night, if he is finally sent to the operating room for a knife, it will really be... life is complete?

Liu Zhaoqing put the informed consent form on the bedside table with a sullen face: "We only need to survive for 5 days, and leave here before the operation. The family members are out of town and cannot come to sign. This excuse can be delayed for a few days. Anyway, I will never go to the operation. room."

Yue Xingwen immediately agreed: "I don't want to have an operation either. Who knows if I can come out alive after entering the operating room. If there is an accident during the operation, it would be an unjust death."

Liu Zhaoqing picked up the coronary CT scan, carefully looked at the stenosis of the artery against the light, and said, "Oh, our heart disease is more serious than I thought, and a stenosis of 80% is considered a grade 4 stenosis. By the way, the night assessment was over last night, right? We won’t come back tonight, right? Do it again, can our hearts take it!”

When Yue Xingwen heard this, his back stiffened slightly. He always felt that his senior brother would be crowed.

Since Dr. Xiao started the ward rounds of the whole ward, the students had no choice but to lie down on the hospital bed honestly. Everyone’s condition was similar, and they were frightened when they heard “operating”. They were afraid that they would really be pushed into the operating room.

It was dark again, and there was still no light outside the window.

As the clock gradually approached the early morning, Yue Xingwen clenched his fists nervously under the quilt.

Don't want to take the night examination room tonight, right?You can't push the students too hard, right?Yue Xingwen prayed silently in his heart, but just as he finished speaking, there was a "ding", and a familiar cold mechanical sound sounded in his ears——

【0:[-] a.m.】

[The second night assessment begins]

【Countdown 3, 2, 1】

Yue Xingwen's expression turned ugly: "Here we go again!"

Liu Zhaoqing swears directly: "Damn, the library is so inhuman!"

Hearing the strange footsteps outside, the two looked at each other helplessly, and quickly fled out the door.

This time without Yue Xingwen's reminder, Qu Weiwei shouted in the corridor: "5G signal tower, I put the signal tower in the upper left corner! Everyone run to the lower right corner!"

Zou Yuhang said: "Damn it, cut off the power to me again, quickly cover me to repair the circuit!"

It seems that the students have all escaped from the battle royale experience?
