Pushing the wheelchair to the front of the interrogation room, Liu Yanshi could no longer enter.

She stopped, leaned over, and gently pressed her face against the left side of the wheelchair. The other hand gently wrapped around his neck and stroked his back.

"Don't be afraid...... Everything will be fine, don't be afraid ......"

Her tone was extremely gentle.

Her eyes were full of love.

"Shi Zuocai" blinked blankly, stretched out his hand to leave her, and as soon as he opened his mouth, saliva trickled down from the corner of his mouth.

The policemen present, including Xing Guangkun, saw this scene and subconsciously sensed that something was wrong.

But now we have to follow the procedure.

The police handcuffed Shi Zuocai, who yelled in horror. Liu Yanwei walked to another interrogation room, looking back at him worriedly from time to time.

It was not easy for "Shi Zuocai" to calm down in the interrogation room, and the policeman sitting opposite breathed a sigh of relief and looked at the file in his hand.

"Your name is Shi Zuo, right?"

"Shi Zuocai" nodded. The policeman looked down and looked again, and the names and student IDs matched.

"You say, you killed Fu Sizhe?"

"Shi Zuocai" raised his head, his eyes glazed, he was silent for about a minute, and began to muttered mechanically:

Fu Sizhe...... Damn ......"

The inquisitor's heart sank.

"Shi Zuocai" continued to lose his mind and muttered:

"Fu Sizhe is a scumbag, a waste, a coward...... He made Ying'er unhappy...... If he's dead, Ying'er won't be unhappy......"

"I was waiting for him at the bus stop on Friday night. I knew he came home late. I told him, 'Ying'er was unconscious at my house,' and he believed it — he was so stupid, he believed it, and he went to my house with me. Then, I knocked him unconscious and fed him sleeping pills, lots and lots of sleeping pills...... He slept until Saturday. ”

The interrogator turned his head a little uneasily and glanced at Xing Guangkun. From each other's eyes, they read the same meaning: this person is not mentally normal.

"Then, on Saturday night, I was stunned by the people looking at the cold storage door. I dragged him into cold storage. I dragged Fu Sizhe into the cold storage and hid in the corner. Then I locked the door – and then, I disguised myself as a beggar and went to the security guard of the neighborhood to trick him into cold storage and stunned him. ”

"I want to kill him, but if I kill him, I'll go to jail. I don't want to go to jail. I'm going to find someone to blame. I looked for those two people and I came up with a solution......"

"I spend money, I want a beggar to do things for me. When a beggar has money, he will do anything. He lent me his clothes and came over at eleven o'clock to lock the cold storage door, as I had instructed...... Turn off the electric switch. I was in the cold storage, pretending to be Fu Sizhe, I woke up the two people and said that we were going to be killed, and everyone was scared, so they went to move the shelves and block the door...... I put the box on it. ”

"Then I lied to them...... Say I'm tired. I'm going to sleep next to the shelf. They ignored me and went back to sleep on their own. ”

"When they fell asleep, I took out chloroform and stunned them again. And then...... Then I dragged Fu Sizhe, left fingerprints, and then dragged him next to the two of them, and shot him to death with a brick...... Then, I just waited. When the snow melts in the cold storage, and when the snow melts, I can push the shelves. I pushed the shelf out and called the beggar to come and open the door. He came to open the door for me and put the boxes back on the shelves...... That way, no one will doubt me......"

After speaking, Shi Zuocai's body trembled, took a breath, and looked at them with a begging look.

The interrogator and Xing Guangkun looked at each other, and their hearts were extremely heavy.

With his confession alone, it doesn't sound like this kind of thing that a person who can't say anything can do - but the confession he provided matches the police's speculation about the entire double secret room.

You must know that the police strictly prohibit the disclosure of the facts of the case to unrelated persons. If this person really didn't do anything, how could he say such a confession that was completely consistent with the investigation at the scene?

The inquisitor knew that the matter was tricky, and asked cautiously:

"Tell me first, where did you get the chloroform you used to stun the security guards and the owner of the fish shop?"

Shi Zuocai was silent for a while and said, "Yes...... School...... Saturday afternoon...... I went to school...... I am, the ...... of my senior year of high school."

There was a knock outside the interrogation room, Xing Guangkun opened the door, and a panting Xia Liang was standing outside the door. He glanced at Shi Zuocai in the interrogation room and motioned for Xia Liang to come in.

When he walked into the interrogation room and saw Shi Zuocai, Xia Liang was stunned.

"The school's laboratory ...... Locked...... But the lock of the school, which is very old, can be used with a student card...... Using the lever principle to pry it open, I went in and took chloroform, and other materials......"

The Inquisitor frowned:

"What material?"

Shi Zuocai muttered: "I...... I'm going to...... Sulfur hexafluoride ......"

Xia Liang suddenly interjected: "It's sulfur and fluorine." ”

Xing Guangkun frowned and looked at Xia Liang, who turned his head solemnly:

"I just went to the Hinako and their lab was stolen. The chemicals that are not seen are sulfur and fluorine, as well as chloroform...... Sulfur and fluorine can be used to synthesize sulfur hexafluoride from combustion. ”

"What is sulfur hexafluoride used for?"

"Shi Zuocai", who had always seemed to be in a state of confusion and low spirits, heard this question and subconsciously replied in extremely fluent language:

"Sulfur hexafluoride is five times denser than air, and when inhaled, it fills the vocal cords around it, and when a human speaks, the vocal cords vibrate, and it is not ordinary air but sulfur hexafluoride that is driven to vibrate. Sulfur hexafluoride is dense and has a low vibration frequency, which can make people speak in a coarse voice. ”

Xia Liang raised his eyebrows, he remembered that when he first entered his brother-in-law's bedroom, his voice did become a little thicker - obviously, it was the effect of inhaling sulfur hexafluoride.

The voice grew thicker...... That's it...... Pretend to be an old man...... So that no one will suspect me. ”

The tone of Shi Zuocai's speech became choppy again, and his pupils were dilated.

Xia Liang's brows furrowed more and more. Silence in the air.

The inquisitor asked:

"Why are you doing that?"

After a period of silence, Shi Zuo said:

Fu Sizhe...... It's scum...... Rubbish...... Coward...... He's dead...... Ying'er won't be unhappy......"

The inquisitor leaned back in his chair and looked at him with a frown:

What do you mean by that? Do you think Fu Yinger hates Fu Sizhe very much? ”

"It's not that I think it's ......" Shi Zuo raised his head and smiled sluggishly: "I'm sure...... There is no one in the world who knows Fu Yinger better than me. I know everything, everything about her, I know everything. ”

"You've known each other for a long time?"

"No...... I didn't know her ...... until she transferred to another school" Shi Zuo Cai tilted his head and smiled, his eyes revealing obsession: "When I saw her, I knew that I was destined for her...... Guardian ......"

"Guardians?" The inquisitor's eyes widened:

"What does that mean?"

"Fu Ying'er cares about me very much......" Shi Zuo Cai muttered: "I also care about her...... In the beginning, we talked on the phone every day, but she didn't want her parents to know about our relationship...... So, instead of me calling her, she didn't have to answer, and I hung up after five rings...... Then she will understand my heart......"

Xing Guangkun frowned, quietly pulled over a criminal policeman beside him, and asked him to investigate Fu Yinger's call records. Xia Liang's heart slowly sank.

Shi Zuocai was still shaking his body in the wheelchair, and said without a word:

"I know everything...... Everything...... Fu Yinger's family affairs...... Her dad owes a lot of money and can't afford it, and her dad isn't a good thing...... Fu Yinger used to live in a very big house, but now she can only live in a very small house, and Fu Yinger's mother is also crying......"

"Wait......" the inquisitor asked, "How do you know all these things?" ”

Fu Yinger...... Tell me ...... in person"

"She told you herself?"

"Right...... In her home. ”

"Have you been to her house?"

"Haven't been...... She's pretending to be talking to her mom, but she's actually talking to me, and we know it, I know it...... I hear it all......"

"How can you possibly hear what they are saying in their own homes?"

"I can hear it, Ying'er loves me very much...... She kept the gifts I gave her at home so I could hear them. ”

Xia Liang narrowed his eyes, and soon realized that something was wrong. He leaned into Xing Guangkun's ear and lowered his voice:

"Listening to the students on Xiaoguang's side, Fu Ying'er was scared and cried by Shi Zuocai...... Team Xing, he can't be a psychopath, right? ”

Xing Guangkun sighed and whispered, "I also hope he isn't." ”

The inquisitor took a breath and asked:

"In that case, why did you choose to turn yourself in?"

Shi Zuocai slowly lowered his head, his shoulders trembled, and when he raised his head again, the facial features of his entire face were distorted.

"Do you still need to ask...... I was betrayed by Fu Yinger. ”

Everyone in the interrogation room was stunned.

"That woman who doesn't know what to do, I have paid so much for her...... As a result, I told her that her trouble was solved by me, and she lost her temper at me, saying that she would call the police and kill me...... This kind of heartless woman...... This kind of woman ......"

Shi Zuocai muttered "this kind of woman" several times in a row, and yelled a few times like crazy. Several detectives pounced on him and pinned him down. He struggled desperately, drooling, snotty, and tearful.

"Let go of me! I don't want to die! Let me go! Let me go...... Mom...... Father...... Let go of my ......"

He cried hysterically, like an epileptic, and in a few moments foamed at the mouth of his mouth.

At the same time, in the interrogation room on the other side, Liu Yanshi was already lying on the table, crying with pear blossoms.

"I have been dating Shi Zuocai for more than a month, and I never knew that he had a split personality...... I didn't know that he had such a personality hidden in his body...... I only found out about this two days ago...... I didn't expect him to do such a terrible thing to Ying'er......"

……

No one expected this bizarre case to come to such a hasty and bizarre end.

The murderer turned himself in - a "nerd" with a high IQ and symptoms of a split personality.

With the confession of "Shi Zuocai", the police gathered evidence at an astonishing speed.

In less than two hours, more and more clues began to surface, confirming "Shi Zuocai's" description of his murder methods and motives.

The police found Fu Ying'er, who had returned home from the funeral home, and she took out an old mobile phone from her bedroom.

According to her, it was only when Shi Zuo forced her to put her at home in the form of threats. said that she and Shi Zuo kept in touch at any time. But Fu Yinger didn't turn on the machine because she was afraid.

The police disassembled the phone, and where the battery was stored, there was a bugging chip.

The description of the phone call every night has also been confirmed: Fu Yinger took out her mobile phone, and there was a missed call at eight o'clock every day in the call record.

It wasn't until the police explained the situation to Fu Ying'er that she knew that it was Shi Zuocai's doing, and she looked surprised.

Especially after hearing that Shi Zuo turned himself in, the shocked look on her face was even more sincere.

Subsequently, the police tracked down the phone number and found that the place where the call was made was an old phone booth a few blocks away in the Tsui Court neighborhood.

This is an old town that is about to be demolished, and it is off the beaten track. After communicating with the shopkeeper across the street, I confirmed the fact that someone would come over to call around eight o'clock every night.

The evidence is ironclad. No matter how unbelievable the people in the task force were, everything that Shi Zuocai confessed was appropriately consistent with the clues of the case. It even explained some of the problems that the police had not been able to investigate clearly.

Why would a good old man like this, who had never made enemies, be brutally murdered - because the murderer was not mentally sane.

Why did Fu Sizhe disappear on Friday night - because the murderer was indeed Fu Yinger's classmate, he was eager to save his daughter, and was tricked into Shi Zuocai's apartment, which kicked off the murder.

The police even searched Shi Zuocai's apartment for chloroform and sulfur hexafluoride, which could be destroyed in the future, the former in a glass bottle and the latter into a balloon.

In addition to these physical evidence, Xia Liang's confession from the investigation before he turned himself in, including the comments on Shi Zuocai on campus, his affair with Fu Yinger, and the stolen chemical materials, all became the most favorable clues to testify that Shi Zuocai killed people.

But no one really felt relieved from the inside.

Because the murderer was a psychopath.

According to the law, if a mentally ill person goes on a rampage and kills people without being able to control his consciousness, there is no convictive sentence.

According to the description of Shi Zuocai's "girlfriend" and classmate Liu Yanshi, his behavior is more inclined to "split personality".

If the symptoms of split personality are not disguised, it will be extremely difficult to sentence the case committed by Shi Zuocai.

No one can be sure whether the psychosis was conscious or not at the time of the killing. This is bound to go through a serious and lengthy psychiatric evaluation and sentencing discussion.

After going through a series of procedures, Shi Zuo changed into prison clothes, put on handcuffs, and was about to be sent to a psychiatric hospital for evaluation. The police also contacted his psychiatrist, Ms. Qin Fenglou, through his medical records.

Liu Yanshi wiped her tears with a tissue and was sent away by the police. Xia Liang looked at her departing back, and endless confusion arose in his heart.

He instinctively felt that the case shouldn't be so simple, but the facts were in front of him, unless he could immediately find another perfect "answer".

The psychiatric hospital's escort car drove to the police station. At the same time, there was another person who was late.

I wish you a good life.

He was still wearing the black suit he had used to go to the funeral home in the morning, and after hearing that Xia Liang had said that someone had turned himself in, he hurried by car. When the police officers of the task force saw her, they were all speechless and had complicated expressions.

"Team Xing."

He walked through the police force and said hello to Xing Guangkun. Xing Guangkun looked at him, sighed silently, and reached out to pat him on the shoulder.

Zhu Ansheng looked solemn and came to Xia Liang's side.

"How's it going?"

Xia Liang pursed his lips and said:

"The murderer has confessed. We found chloroform at his house...... Conclusive. ”

"What about people?"

"I'm preparing to be escorted to a psychiatric hospital."

Zhu Ansheng narrowed his eyes slightly, looking a little irritable. He reached into his pocket and pulled out a cigarette.

There was a commotion at the door of the police station, and Xia Liang said, "It's coming." Everyone turned their heads, and at the door, several criminal policemen pushed wheelchairs and brought Shi Zuocai out.

The wheelchair was rolling on the brick floor, and "Shi Zuocai", who had just woken up from a coma, had a dull gaze, and there were traces of saliva on his neckline.

All the way through the queue of task force members, a pair of silent eyes fell on him.

At the bottom of everyone's heart, there was an inexplicable sense of frustration.

The staff of the escort car got out of the car, took out the stretcher from the back door, and prepared to carry it into the car, at which point Zuo would be put on a special psychiatric gown, his hands tied up in a staggered manner, and sent to a psychiatric hospital.

The officers silently surrounded him.

Zhu Ansheng's expression was complicated, and while shouting to borrow it, he squeezed to the front.

The staff turned the wheelchair around. Someone took out a psychiatric gown, someone was assembling a stretcher. There was a silent hustle and bustle everywhere.

Zhu Ansheng and Shi Zuocai looked at each other.

At a certain moment, Shi Zuocai's eyes moved slightly, and his dull pupils returned to clarity. He wrapped his left hand in front of him, and at an angle that no one could see clearly, he quietly stretched out the index finger and thumb of his right hand to Zhu Ansheng.

That's the gesture of the "gun".

The "gun" in his hand quietly pointed at Zhu Ansheng.

The corners of Mr. Demon's mouth hooked up a bewitching smile, his lips moved slightly, and he silently made a lip shape-

“Bang.”
