Nangong Yi nodded and confirmed Jiang Xinyu's words, bowed her head and whispered to us that she knew about this matter, because the murderer's mental illness is a very strict matter after being caught, and once he is diagnosed with mental illness, he cannot be admitted to prison, and he is first sent to a psychiatric hospital for treatment.

The reason why there is cooperation between Halt Medical College and the police is because Hop Tak Medical College was formerly an extremely famous psychiatric hospital, which is unique in the treatment of diseases in this area, so all murderers with mental illness will be arranged here.

Although I am a forensic doctor, although I also know a little about psychiatry, I know very well that the difficulty of the treatment of this kind of mental illness requires a lot of time and effort, and the treatment methods are different from the conventional, it is completely understandable why Jiang Xinyu built this place so tightly, these people seem to be normal, but their thinking and ideas are completely different from our normal people, and they can't measure the mental state of these people according to normal standards, let alone predict what they are going to do.

But this is the only place where you can go after the stairs, and from the video taken by Qiao Kewei, the last place where the four dead disappeared is also here, and I am somewhat interested in this closed room.

"Can you show me the files and medical records of these patients?" I asked Jiang Xinyu politely, after all, doctor-patient files are confidential, and even if I investigate a case, I follow my identity as a doctor first.

"In principle, it is not allowed, but since it is helpful for you to investigate the case, I will have people sort out the files and medical records and send them to you." Jiang Xinyu replied seriously.

I nodded gratefully and looked back and forth in the ward of this university, perhaps because of these patients, I always felt that this place was eerie and terrible, Jiang Xinyu accompanied us until the end of the investigation of this place by colleagues in the identification department.

The results of the temporary investigation left us somewhat at a loss, there were no signs of a fight in this ward, and no fingerprints and footprints taken from the bodies of the four deceased had been found here, and it was initially certain that the four deceased had not been here.

Coming out of the basement, I saw Wen Jike lock the iron door again, and then put the key carefully, I suddenly asked with interest.

"How many keys are there to this iron door?"

"Just a handful." Jiang Xinyu replied with a nak-to-nail answer. "Wen Jike is mainly responsible for the diet of these seriously mentally ill patients and the cleaning of the wards every day, and these patients are usually arranged in the wards except for time-limited activities outside, and no one except the medical staff can contact them without my permission."

"Why?" The prince looked up and Jiang Xinyu looked at each other and asked very calmly. "Why don't these people have contact with the outside world?"

"......" Jiang Xinyu showed a sluggish expression in front of us for the first time, she seemed to have something she didn't want to tell us, and after a while she replied in a heavy voice. Each of these mentally ill patients has a strong psychological suggestion and the ability to control their thoughts, and although they receive treatment, they have little effect, even if they are imprisoned in the ward, they have the ability to control others through contact with outsiders, which is why we hired Wen Jike. ”

"He ......," Yun Duruo asked curiously, looking back at Wen Jike. What is the relationship between the condition of these patients and the employment of Wen Jike? ”

"Wen Jike has suffered a speech disorder due to a car accident, and his hearing function is very poor, his brain has suffered from traumatic sequelae, and he is slow to respond to external stimuli, and we have repeatedly tested him when we hired Wen Jike." Jiang Xinyu told us expressionlessly. "It's difficult for a person like him to be subtly controlled by the mentally ill people here in terms of language and behavior, and we also take into account that the detention and treatment of patients here are arranged in this way."

Jiang Xinyu's explanation is very reasonable, I also studied some books on psychology when I was in college, mental illness refers to a serious psychological disorder, the patient's cognitive emotion, will, action behavior and other mental activities can have lasting obvious abnormalities, action behavior is difficult to be understood by ordinary people, under the domination of pathological psychology, there are suicide or attack and hurt others.

Normal people are extremely susceptible to the temptation and misdirection of psychopaths, and most people think that psychosis is produced after being stimulated, but in fact, until today, psychiatric research still believes that most psychosis is a disease of unknown etiology.

Of course, some mentally ill patients have encountered unpleasant things before the onset of the disease, but more of them are closely related to the internal factors of the patient, and they may encounter various setbacks and difficulties in life, but the number of mentally ill people is a minority, and some patients do not have any mental stimulation before the onset of the disease.

Therefore, mental stimulation is only the trigger, not the cause, on the contrary, neurosis is generally caused by real or traumatic psychological pathogenic factors in childhood.

I can understand the reason why Jiang Xinyu hired Wen Jike, detaining and treating these severe mental illnesses is an extremely dangerous thing in itself, and Wen Jike's special condition will not affect him, Jiang Xinyu wants to minimize all any subtle emergencies, and it can be seen that she is also a very strict woman.

Early the next morning, Jiang Xinyu arranged for someone to send over the files and medical records of all the patients in the basement, and I carefully looked through the information of each of the patients who were detained, and sure enough, as Jiang Xinyu said, if each of these patients is removed from mental illness, they are extremely vicious, and if only in terms of the harm caused, then everyone in the basement is a death row prisoner with ironclad evidence!

However, in terms of sentencing, because they are determined to be mentally ill, they cannot be criminally punished according to the standards of normal people, because most mental illnesses, such as schizophrenia and depression, are born diseases, and are neurological diseases caused by genetic changes.

However, the so-called murder of a mentally ill person is not a crime, in fact, it is a misunderstanding, and the law does not stipulate that a mentally ill person cannot bear criminal responsibility only if he commits an act when he is unable to recognize or control his own behavior.

I then looked through the medical records of these patients, and the results of the treatment had little effect, but it was not a problem of the doctor's medical level, because most of the mental illnesses are brain dysfunctions and lesions caused by congenital polygenic changes, so drugs can only treat the symptoms but not the root cause, and it is absolutely impossible to cure the root cause of the disease, because the root cause of the disease is genes.

"You've been looking at the files and medical records of these patients all morning, what do you see?" Han Yu dragged a chair and sat next to me and asked.

I shook my head, and after a cursory look at the medical records and files in front of me, they were all rare mental patients, as Jiang Xinyu described, there were several cases of illness that I had only seen in the books.

"Since it's useless, what are you doing with this?" Yun Duruo took a few steps back and forth and asked.

"I always felt strange about the room with the door locked." I looked up at her and asked thoughtfully. "You...... Don't you feel that way? ”

"This is an investigation of the case and everything must be based on evidence, not based on feelings." Yun Duruo sat down and answered seriously. "The people in the basement are all mentally ill, I don't know if these people have the ability to attack, but the two-layer glass door blocks them inside, I don't think they will have the ability to penetrate the walls no matter how powerful they are."

"What do you think is strange about that ward?" The prince asked calmly.

"I ...... I don't know, it's just the feeling. I took a deep breath and rubbed my forehead, and found that what Yun Duruo said was right. Those people are very dangerous, but Jiang Xinyu said that except for Wen Jike, who has the key, no one else can enter, do you think there is a problem with Wen Jike? ”

"Wen Jike: What can be wrong with a person with different degrees of physical and psychological disabilities." Yun Duruo glanced at me and said angrily. "It's okay for you to be a forensic doctor, let you investigate the case and even go in the wrong direction, now it's the four ...... No, it's the cause of death of the nameless deceased, what do you keep struggling with those patients and an administrator? ”

"Wen Jike really has no problem, at least he has nothing to do with the murder that happened in dormitory 403 at the beginning." I just wanted to refute Yun Duruo when Nangong Yi, who walked in from outside, interrupted me. "After learning that Wen Jike was the only person with the iron door key, I also set him as a suspect, I specially learned about the investigation of Wen Jike's movements at the time of the crime, the death time of the 403 dormitory girl was two o'clock in the morning, and that night because the security guard of the north gate of Hede Medical College had something to do and asked for leave, so Wen Jike was arranged to be on duty at the north gate that night, there was a surveillance video at the gate, I checked that Wen Jike was in the duty room all night, and he didn't leave until nine o'clock in the morning."

Hearing Nangong Yi's words, I fell silent again, lit a cigarette, stood up, walked a few steps back and forth in the room, and muttered to myself.

"Judging from the video taken by Qiao Kewei, the last place where the four deceased disappeared was when they went down the stairs, and in the video there was a light that we have not been able to explain so far, and the results of the on-site investigation also showed that there could be no other space under the steps, and the only passage was the locked iron door."

"It's safe to assume that the four women had indeed been to the basement of Building 19, and that the light that appeared might have been the iron door opened." The prince shook the rosary in his hand and said unhurriedly. "I've been standing on the steps before, and when the iron door is opened, there is indeed a light coming out, and it must be more visible at night."

"That's what the prince meant, and I'm also assuming that if you say it's possible that the four deceased actually entered the basement ward in the end." I nodded and took the prince's words. "And the people who are admitted to it are all extremely vicious murderers, you must know that there are many causes of mental illness, and some of these people may be stimulated by people who suddenly appear and cause the onset."

"I remember Jiang Xinyu seems to have said that each of these mentally ill patients has a strong psychological suggestion and the ability to control their thoughts, although they receive treatment but have little effect, even if they are imprisoned in the ward, they have the ability to control others through contact with outsiders." Yun Duruo looked back at me and said thoughtfully. "If you follow your hypothesis, is it possible that the four deceased who broke into the basement ward by mistake because they listened to the rumors were psychologically cued or behaved and thus what happened in the ward?"

"That's right! That's what I mean when I look at the files and medical records of these patients. I nodded in reply.

"Wait, you all say this, it seems that you have ignored a crucial fact." Han Yu suddenly interjected.

"What facts?" I asked.

"The female student in the 403 dormitory, you have determined that the time of death is 2 o'clock in the morning, but your inferences and assumptions are all based on ......," Han Yu said unhurriedly. It's all based on the fact that the four dead people didn't die, I don't believe that people two hours after death will go to another place, of course, this possibility exists, you all know in your hearts, if it's really the ghosts of these four girls after they died, then I think since they have all become ghosts, there is nothing to be afraid of. ”

I sighed heavily, Han Yu's words almost completely overturned my assumptions, this is the most bizarre and weird part of the whole case, why did the four deceased still appear two hours after their deaths, if it was really a ghost after death, but in Qiao Kewei's video, we could all see that Nie Bingwan was scared and frightened from the bottom of her heart, since she was dead, what else was she afraid of.

Of course, if it is really a ghost after death, then there is no such thing as going to the basement to be attacked or killed, and it is impossible for a person to die twice, so they disappear on the steps leading to the basement and there is only one last explanation...... Transcript:

The nineteenth step really appears in the video, and Li Hajun told us that in the supernatural rumors of this medical school.

The nineteenth staircase is a passage to Hades!

For such rumors, it may be absurd in many people's hearts, but for us in the room, it is not that there is no such possibility, nothing will be groundless, since there are such rumors, there must be a reason, but now the research does not seem to be of much help to the investigation of the case.

"Whether the rumors are true or not, the top priority is to first find out the cause of the mysterious deaths of these five deceased." I snuffed out the cigarette butt in my hand and took a deep breath. "Whether it's suicide or murder, there will always be a reason, and finding that reason may be the key to solving the case."

"Where are you going to start?" Nangong Yi asked.

"Autopsy!" I replied in a nutshell.

There's another chapter poking back
