Outside the door, Miss Miyano, who was standing in the corridor, heard her boyfriend's 'call', was stunned for a moment, raised her hand and pointed at herself, feeling indescribably confused.
What's going on?
Why is the interrogation coming to me?
She is definitely not a suspect!
Absolutely innocent!
But Sakaki Makoto is serious and has a solemn attitude. He is as meticulous as a judge in a courtroom. No matter whether the defendants in the audience are parents or children, they must be judged strictly according to the law.
"Hey, hey, hey, isn't she your girlfriend?"
Although Yamamura So was not very smart, he had a good eye. He guessed their relationship from Sakaki Makoto's attitude towards Miss Miyano just now, and was even more confused.
Of course police officers cannot be partial to each other, but who doesn’t have some ulterior motives?
The first person Sakaki Makoto wants to interrogate is his girlfriend. Isn’t he afraid that he won’t be allowed to have sex with her when he gets home at night?
"It is precisely because she is my girlfriend that I want to prove her innocence."
Miss Miyano glanced at her boyfriend and said nothing more. She walked straight into the ward, hung the IV on the iron bar beside her, and sat opposite him.
"Ask."
"Um."
Sakaki Makoto nodded, signaling Yamamura Sou to assist in recording, while he himself served as the chief judge:
"The incident happened at 10 o'clock at night. Where were you during this period?"
"I'm on the second floor, in the corridor outside Yoshio Ogawa's bedroom."
"Who can testify for you?"
"There were many people in the corridor at the time, and they can all testify for me, including Ogawa Yoshio's wife, who left the bedroom at 10 o'clock."
"Very good, your alibi is established. Next question is, did you enter the kitchen or touch the charcoal stove before the incident?"
"No."
"What is the purpose of your visit to the Ogawa family?"
"For world peace."
Miss Miyano answered without hesitation, and Yamamura So was dumbfounded listening to her.
"I've finished my questions. Inspector Yamamura, do you have anything to add?"
"ah...."
Shancuncao's brain crashed for a while before he came back to his senses:
"No, I think... You guys are in the same group, is there any point in asking these questions?"
"Of course."
Sakaki Makoto said without hesitation:
"Since we are investigating a case, we must have the right attitude. We are outsiders and suspects, so we must prove our innocence."
"oh...."
As if he understood it, Shancun Cao nodded, feeling awe-inspiring.
As soon as the police arrived at the scene, Makoto Sakaki proved that he was not a suspect. However, his not being a suspect does not mean that Miss Miyano, Conan and others are not suspects either. The identity of a detective is not a protective umbrella and cannot be used to escape guilt.
"You may leave now. The next person, please ask Ogawa Yoshio's wife to come in."
Makoto Sakaki smiled at his girlfriend, but Miss Miyano rolled her eyes at him, picked up the IV bottle, stood up and left the room.
soon....
A hunchbacked old woman came in. She refused her son's support and walked into the ward by herself and sat opposite Sakaki Makoto and Yamamura Cao.
After she sat down, Sakaki Makoto asked the first two questions again, and the answers he got were similar. The old woman acted with them together. She had never been to the kitchen or even the courtyard. She was completely under the surveillance of Sakaki Makoto and others.
You could say....
Apart from Sakaki Makoto and the others, the old woman is the least suspicious one.
If she wanted to kill Yoshio Ogawa, it would be so easy and effortless.
After the routine, Sakaki Makoto finally got to the point. He frowned and asked seriously:
"Who suggested installing the central air conditioner in Xiaochuan's house?"
"Um?"
The old woman frowned, realizing that the situation was not that simple. She thought about it carefully and said:
"It was the younger generation of the family who jointly requested it at the dinner table. I'm not sure who proposed it, but the first person who said we should install central air conditioning was Cheng Zhi."
"Ogawa Seiji... OK, I understand."
"Why do you ask that?"
The old woman stared into Sakaki Makoto's eyes:
"The central air conditioning was installed several years ago. If something was going to go wrong, it would have happened a long time ago. Why wait until now?"
"Because the criminal used the fresh air system of the central air conditioner to commit the crime."
Sakaki Makoto said calmly:
"The prisoners added silica to the carbon furnace and used high temperature to produce relatively pure high-concentration carbon monoxide. They then placed it at the air inlet of the fresh air system and used the pipes to circulate it so that the carbon monoxide was dispersed throughout the rooms."
"Under normal circumstances, the various pipes of central air conditioners are not interconnected. Only central air conditioners with fresh air systems will have their pipes connected to facilitate air purification."
"So I think the person who proposed installing a central air conditioner with a fresh air system is the most suspicious."
Hearing this, the old woman's eyes flashed. I don't know what she was thinking of, and her face was gloomy.
"Do you remember anything?"
"....No."
The old woman shook her head:
"It's been so long since I last saw it, I can't think of anything and I can't remember it very clearly."
This sentence seemed to be trying to cover up the truth, so Sakaki Makoto smiled slightly and did not ask any further questions. He just told the old woman that she could leave and let the next one take her place.
A few seconds later, Ogawa Yoshio's eldest son, Ogawa Masaki, walked into the ward. As soon as he sat down, he asked in a deep voice:
"Is someone trying to murder my father?"
"yes."
Sakaki Makoto said bluntly:
"So I need you to tell me everything you know, for your father and for your own innocence."
"Okay, just ask."
"First question, who suggested installing the central air conditioner in your home?"
Regarding central air conditioning, it has been a few years since I last remembered it, so I can’t remember many details. However, Masaki Ogawa still tried to recall them and said carefully:
"In the past two years, the climate was unstable and the temperature was unpredictable. Our house is old, so there were a lot of insects and ants in the summer. The room was as hot as a steam oven, so everyone wanted to install air conditioning."
"But we have too many rooms in our house. If we install wall-mounted air conditioners in every room, the outdoor units alone would fill up half of the courtyard. So we discussed it and decided to install a home central air conditioner. It was not just a suggestion from one person alone."
"I see. Then the second question is, who is responsible for the purchase and installation of central air conditioners?"
"It was originally my turn, but I had an academic paper to write at the time, so I handed the task over to my wife. However, my wife knew nothing about electrical appliances, so she asked Cheng Zhi to help her buy it."
"It's Ogawa Seiji again..."
Yamamura Cao, who was writing quickly at the side, muttered something and recorded everything Ogawa Masaki said.
“The third question is, how much do you know about silica?”
"Silicon dioxide?"
Ogawa Masaki was stunned for a moment and said:
“The academic paper I wrote a few years ago was about silica.”
