The principle of proximity, which is often mentioned in "Criminal Psychology", is the idea of ​​​​murders committing crimes. People can't help but be nervous in unfamiliar environments and make mistakes easily, but they will be more confident about their familiar environment and the people around them.

Therefore, the murderer of a serial murder case often chooses the people who are close to him and who are close to him first. After killing one or two people, the murderer will have a sense of accomplishment in killing someone successfully, and his courage will gradually increase, and the scope of the crime will also be increased. Expand accordingly.

This is the basis for Yue Xingwen to determine the location of the murderer.

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

-------Doctor's Office Area---------

05/04/03--koukou--48/49/50

08/07/06--koukou--45/46/47

11/10/09--koukou--42/43/44

14/13/12--koukou--39/40/41

17/16/15--koukou--36/37/38

20/19/18--koukou--33/34/35

23/22/21--koukou--30/31/32

26/25/24--koukou--27/28/29

VIP Ward---Koukou---VIP Ward

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

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

The ward number starts from No. 3 and ends at No. 50 in the upper right corner in order from the upper left corner.

Yue Xingwen pointed to the map and explained to the students: "The entire cardiovascular ward is a 'hui'-shaped corridor structure, with the doctor's office above and the nurse's station below. The left and lower right corners are VIP wards, with 8 wards on both sides of the corridor, 24 beds. Top left 3/4/5 bed, bottom bottom bed 24/25/26; bottom right starting with bed 27/28/29 and ending with bed 48/49/50 in the upper right corner."

When everyone saw the ward distribution map he drew, just like taking notes in class, they quickly took a blank piece of paper and copied it, and marked their corresponding bed number and the location of the deceased.

Yue Xingwen also marked the positions of the five deceased with asterisks, saying: "The two patients who died at 1 a.m., beds 15 and 24, were all close to the corridor. That is to say, the murderer gently pushed the door in the middle of the night. , two steps forward, you can directly add vasoconstrictor drugs or toxins to the patient's syringe, which is very convenient for committing crimes."

Liu Zhaoqing finally understood: "The first time the murderer committed a crime, he would choose someone close to him. After killing someone, he would be able to return to his ward as soon as possible to avoid being caught by other patients or doctors and nurses. The most recent of the deceased...that is, the patients in the wards of 18/19/20 and 21/22/23?"

Ke Shaobin took a closer look with his glasses, and suddenly realized: "The 15-bed deceased is on the left side of his door; the 24-bed deceased is on his right side. The round-trip time to commit the crime will not exceed 10 minutes, which can also be explained. The death time of the two people was only 10 minutes apart? Because they are close, it is convenient for the murderer to commit the crime?"

Yue Xingwen nodded: "That's right. There are doctors and nurses on duty in the ward at night. Once the patient is out of shape, the nurse station will call the police. The murderer must quickly inject the patient with dangerous drugs and slip back to the ward within 10 minutes. Otherwise, the nurse station will After calling the police, the doctors will rush to the scene to rescue them, 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 then sneak back into the ward. The deceased were on his left and right sides, very close to him. After killing people, he could observe the rescue situation of the doctors and nurses at any time.

Yue Xingwen went on to analyze: "After killing these two people, he became more courageous. After two hours, when he committed the crime again at 3:30 in the morning, he chose a farther target. 5 beds and 50 beds, the distance The doctor's duty room is relatively close, and there happens to be a bathroom there. He can pretend to go to the bathroom, kill 5 beds first, then kill 50 beds, and then quickly return to his ward."

"At 5 in the morning, when he committed the crime for the third time, he chose the farthest target, and even swaggered around in front of the nurse's station, touched the ward in the lower right corner from the left corridor, and killed Patient 33."

Seeing Yue Xingwen's complete drawing of the murderer's moving route, the classmates 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, that must be It is to find the closest one first, and finally kill the farther one."

Thinking that the murderer had been in and out of his ward last night, and quietly killed the patient in the next bed, everyone's backs shuddered, and a layer of goosebumps fell.

Liu Xiaoxiao shuddered, gritted her teeth and asked, "Xingwen, are you sure that the suspects are these patients? Is it possible for doctors and nurses 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, it will not cause suspicion, no need Follow the rule of 'kill the near first, then the far away'. Medical staff can commit crimes at random, and the time and path of our analysis are meaningless."

He opened the information of the medical staff in the ward and focused on the duty list last night: "This is the list of doctors and nurses on duty last night. Let's recall your impressions of them first and see if there are any doubts about their information. The possibility of the medical staff committing the crime mentioned by classmate Liu Xiaoxiao cannot be ruled out hastily."

Yue Xingwen distributed the information of doctors and nurses to let everyone find clues carefully.

Liu Xiaoxiao took the information and read it again, and said, "This is the nurse sister in our ward, with a gentle personality. I heard her chat with people yesterday. She is going to get married next week, and she even sent invitations to her colleagues. The happy event is approaching, she should Isn't that the butcher who killed five people in a row?"

Qu Weiwei, who was in the same ward, added: "I noticed that this nurse wore a diamond necklace around her neck, saying that it was given by 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. The little girl who just graduated, is only in her 20s and has a shy personality. When I asked her yesterday, she blushed and didn't look like a murderer. what?"

Ke Shaobin looked serious: "The third is the nurse in charge of our ward. She had a quarrel with her husband. I heard her chat with someone yesterday, and she was obviously in a bad mood. I asked her questions, and she also murdered me. A few words. She seems to have just returned to work after maternity leave, and she looks anxious. But it's not enough to kill a patient to vent her anger, right?"

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

Everyone: "…"

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

Yuexing text did not suspect that it was the nurse who committed the crime. The three nurses had no motive for committing the crime. Besides, after the nurses changed the medicine, they would habitually throw the medicine bottle in the trash can for medical waste collection next to the nurse station. The bucket is cleaned every day, so there is no need to worry about the evidence being discovered. He and Liu Zhaoqing rummaged through the trash can and found no clues.

The reason why he analyzes and excludes one by one is only to allow the students to recognize his inferences. Otherwise, the final answer is wrong, and the students will blame him for not analyzing it properly, and the monitor is not so easy to be.

Yue Xingwen looked at Liu Zhaoqing: "Senior brother, do you think there is any suspicious person 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 shrewd and capable. He graduated with a Ph.D. in cardiovascular specialty. Years of reading, writing papers, training, and finally becoming the attending doctor, and came to the ward to kill? It’s not so crazy, unless he’s psychopathic.”

Yue Xingwen nodded: "Well, antisocial personality disorder, or psychopath, is it possible to 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, his resume shows that he was transferred from another hospital and has only worked here for a year. No way; there is another Sun Liang who is an intern, 25 years old, just graduated from graduate school, doesn't seem to have any motivation?"

Yue Xingwen thought for a moment, and finally came to the conclusion: "Three nurses can be ruled out with high probability. The three doctors on duty who stayed in the ward last night are pending. 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 people, and there is no way to kill indiscriminately in a bad mood. What's more, last night's murderer was quite well prepared. It was obviously not an impulsive crime, but a long-planned murder. The murderer also knew the relevant theoretical knowledge of cardiovascular specialists.

Yue Xingwen picked out the patient information from the two wards and handed it to the students: "6 suspects, an 18-bed old lady who just had an operation, is currently wearing an oxygen mask, is in a coma, and has difficulty moving herself. The first one is ruled out. ."

Zou Yuhang added: "The two grandfathers with beds 22 and 23 live next door to us. They are both over 70 years old. One is a cement worker in a decoration company and the other is a carpenter. The two clearly knew each other and called each other. , and chatting about their grandson's exam results in the corridor, they seem honest and honest, shouldn't they have no medical knowledge? I don't think they are too suspicious."

6 people ruled out 3, and the range narrowed again.

Yue Xingwen opened the information of the remaining three people: "19 beds are retired professors of the medical school; 20 beds are engaged in pharmacy-related work in the hospital; 21 beds have been medical representatives. All three of them have received medical education and should know How to let the sudden death of myocardial infarction patients, the age is between 50 and 60 years old, the condition is not serious, and they all have the conditions for committing the crime. The next step is to find the motive for committing the crime. "

Yue Xingwen couldn't understand, what was the reason 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, walk in with a blank 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 in a class meeting.

When they met the doctor's icy gaze, everyone quickly lowered their heads. Ke Shaobin was in a hurry, closed the data in the laptop with one key, opened a movie that came with the computer, and said with a smile: "Doctor, everyone is so boring, let's watch a movie together." What he opened was a horror movie "The Grudge", and a female ghost crawled out of the ground.

Dr. Xiao's face was even more ugly: "A group of heart patients gathered here to watch ghost movies, do you think they have lived too long?"

Everyone: "…"

Doctor Xiao sternly said, "You're not going back yet?!"

After being stared coldly by the doctor, the classmates immediately scattered and fled back to their ward quickly.

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 lightly, "The coronary CT diagnosis results of 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 stenosis is 80%." Then he took out another film and handed it to Yue Xingwen, saying, "You have an 80% stenosis of the left circumflex artery. , the condition is quite serious, and it has reached the standard of surgery. Fortunately, you are still young and have no other underlying diseases. If you do interventional surgery, the prognosis is not bad. "

Yue Xingwen and Liu Zhaoqing looked at each other and blurted out, "Do you have surgery?"

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

Yue Xingwen took over the consent form and looked at a lot of "dangerous situations" and "possible postoperative complications" listed above.

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 holding down his temples with a headache: "Won't we really send us to the operating room? This course experience is too rich." He usually rarely gets sick. Entering the hospital, encountering a serial murder case, and running for his life at night, if he was sent to the operating room for a knife in the end, it would really be... a complete life?

Liu Zhaoqing put the informed consent form on the bedside table with a sullen face: "We only need to survive for 5 days, and we can 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 surgery either. Who knows if I can come out alive if I enter the operating room. If there is an accident during the operation, it would be too wrong to die."

Liu Zhaoqing picked up the coronary CT film, looked at the light and carefully looked at the location of the artery stenosis, and said, "Alas, our heart disease is more serious than I thought, 80% of the stenosis is already a grade 4 stenosis. In other words, the night assessment has ended last night, right? Will it come back tonight? Do it again, can our hearts take it!"

When Yue Xingwen heard this, his back froze slightly, and he always felt that his senior brother would have a crow's mouth.

Since Dr. Xiao started the ward rounds in the entire ward, the students had to lie down in the hospital bed honestly. Everyone's condition was similar. When they heard the "operation", they were all terrified, for fear that they would really be pushed into the operating room.

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

The clock was gradually approaching the early morning, and Yue Xingwen clenched his fists nervously in the bed.

No night exams tonight, right? You can't push the students too hard, right? Yue Xingwen prayed silently in his heart, but just after saying this, there was a "ding" sound, and a familiar cold mechanical sound sounded in his ears—

【0:00 in the morning】

[The second night assessment begins]

【Countdown 3, 2, 1】

Yue Xingwen's face was ugly: "Here again!"

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

Hearing the strange footsteps sounding outside, the two of them looked at each other helplessly and quickly escaped from the door.

This time without Yuexingwen'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, power off Laozi again, cover me to repair the circuit!"

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