"The survivors of the crime scene are all here." Cheng Cheng told the guards to open the door to the detention room and said, "People who have experienced that tragedy are not quite mentally right. Because the incident has not yet been clarified, these people are not suitable to be sent to other hospitals for treatment, so they can only be arranged with us first. On the one hand, our detention cells also have isolation rooms, where psychiatrists can be arranged for psychological treatment, and on the other hand, the safety of these witnesses can be guaranteed. ”

On duty in the detention room was a female police officer, very young, with a ponytail, the first impression was the image of the energetic girl next door, she took the three of us directly to the direction of the isolation room, and said to Cheng Cheng: "Team Cheng, these people are all mentally troubled because of the huge stimulation, and even a few of them have serious violent tendencies, which is very dangerous. We have questioned them several times, but we have received no useful information. ”

Cheng Cheng is now in turmoil, his wife and daughter are missing, and now this big case is confusing, and he has no desire to talk, just humming a few times, which is considered a response.

The little policewoman was obviously dissatisfied with Cheng Cheng's answer, and before she could say more, Shen Tangzhi coughed and interrupted: "Okay, Xiao Zhou, don't say a word, Team Cheng will only be more eager to solve the case than you." ”

"Yes, Section Chief Shen." The little policewoman known as Xiao Zhou seemed to be in awe of Shen Tangzhi, so she quickly closed her mouth and stopped talking.

"Everyone is here, you can pick one." In front of the isolation room, Shen Tangzhi turned around and said to me, "But I have said it first, although Section Chief Cheng insists on hiring you as a temporary consultant of the Criminal Investigation Bureau, if you try to fool yourself with the tricks of charlatans, I will definitely prosecute you for the crime of obstructing official business." ”

The old knife raised his eyebrows, and his face was suddenly full of unhappiness, I saw Cheng Cheng on the side with an embarrassed face, so I stopped the old knife, I only nodded at this section chief Shen who spoke without giving anyone face, indicating that he understood.

Then, I was not polite, I looked directly at the isolation room by myself, and looked for a suitable candidate through the observation window on the door of the isolation room.

Walking to the door of the first isolation room, I opened the observation window, and the little policewoman, probably curious about what I could see, followed.

In this isolation room, a woman in her thirties was closed, and she noticed that someone had opened the observation window on the door, and the woman, who had been spinning in circles in the isolation room, immediately became hideous and pounced on me - but because the walls and doors inside the isolation room were all wrapped with thick cushions to prevent the prisoner from harming himself - so the woman's pounce only made the door of the isolation room shake slightly.

But the woman did not relent, rushing to the door again and again, and the door of the isolation room was slammed into a round of muffled sounds.

The woman's hideous expression, the hair-raising hiss, made the little policewoman standing behind me take a small step back in fright, but I was unmoved, and observed the frantic woman in the isolation room with an almost indifferent eye.

After looking at it for a while, I closed the observation window, walked to the next isolation room, and opened the observation window.

In this isolation room was an old man who was kneeling naked on the floor, his clothes tossed aside.

The policewoman Xiao Zhou explained to me that since this old man came to the police station, he has stripped off his clothes and knelt on the ground and kept kowtowing, no matter how much persuasion is useless, the old man does not communicate with you at all, it is useless for you to force him to put on clothes, and it will be like this again after a while. Since the old man did not show any aggression/behavior, the police could not take compulsory detention measures and could only let the old man do so.

When I looked, sure enough, the old man was kneeling on the ground, a white-haired head was knocking on the ground, his white and flabby skin was crumpled and covered with a scrawny frame, and he kept shaking with the kowtowing movements, and there were words in his mouth, but I couldn't hear what he was saying because of the distance.

I looked at the rooms one by one, and after looking at all the isolation rooms, I returned to the door of one of the isolation rooms, and just stopped for a while, I heard Shen Tangzhi's somewhat impatient voice: "Have you decided to want this person?" ”

Looking at the bald tattooed man in the isolation room who was banging his head against the wall, I nodded: "He's more in line with the requirements." ”

"This man's violent tendencies are the most serious of these patients, and in order to control him, there was also a senior brother who was injured a little - what do you want him to do?" Policewoman Xiao Zhou asked.

Shen Tangzhi glanced at Xiao Zhou: "Don't ask what you shouldn't ask." ”

The policewoman Xiao Zhou stuck out her tongue and closed her mouth.

I said to Cheng Cheng and Shen Tang: "That's right, I want this person." Who is he? ”

Cheng Cheng motioned for Xiao Zhou to answer, and the little policewoman thought about it and said seriously: "A little gangster, I don't know the specific name." Their leader was slashed and hospitalized by the enemy, and he went to accompany him for the night. The trauma department was on the first floor, so he was able to get away with it. ”

"That's it." I clapped the board.

Cheng Cheng brought in three male policemen and brought the tattooed bald man into the interrogation room, and his bald limbs were handicaled to an iron chair firmly fixed to the ground, but the thug seemed to be really crazy, kicking and kicking, and even opening his mouth to bite someone, and a group of people spent a lot of effort to get him.

"Alright, you all go out. This interrogation was top secret. It's okay for me and Section Chief Shen to be directly responsible. Cheng Cheng instructed the three police officers.

The three police officers agreed in unison, and then pulled Xiao Zhou out of the interrogation room with a curious face.

The interrogation room was very simple, with an iron table in the middle, and several chairs on either side of the table, among which the prisoner's chair was also made of iron and bolted to the floor.

On the table was a bright light, some tools for recording confessions, such as voice recorders and notebooks, and in the corner was a surveillance video camera.

The wall on one side of the interrogation room is made of special high-intensity polarized glass, so that those who are inside cannot see the outside, but those who stand outside can clearly see the scene inside the room.

I stayed in the interrogation room, and then my first move was to step aside and turn off the surveillance footage.

Shen Tangzhi immediately warned me through the headset, reminding me not to do anything that violated the torture law, because the person in the interrogation room could only be characterized as a criminal suspect, so I ignored her and took off the headset directly.

"Now it's just the two of us. I'm curious, how the hell did you kill so many people? ”

With that, I unwrapped the handcuffs on one of my bald hands, shoved the key into the other's hand, and added a small police hunting knife.

"Open it yourself. Oh yes, I have this with you, maybe you'll like it. ”

Then I stood aside and just looked at each other silently.

According to the live videos that Cheng Cheng showed me, coupled with the discussion with Lao Dao, I have deduced in my mind the general outline of the tragedy of the municipal Chengnan Hospital.

Given the scale of this incident, it is almost completely impossible for the perpetrators to infiltrate and escape quietly if they were outsiders. Video footage from the scene and subsequent investigations also support this hypothesis - all the culprits and victims were all from the hospital.

And just now I got clear information from Shen Tangzhi, the head of the forensic forensic section: the time of death of the victim was roughly between 12 o'clock in the morning and 2 o'clock in the morning.

In just two hours, 384 people were killed with such troublesome murderous methods, and these people were scattered all over the hospital, even the inpatient building where the victims were concentrated had 20 floors - there were also patients with night emergencies who were also killed that night.

The killings on the night of May 17 took place in almost every area of the hospital at the same time.

And that weird dark red chain......

Common sense can no longer be applied to this incident.

So I had to take some risks and use extreme measures.
