Makoto Sakaki has no idea who the real IQ ceiling is in this world.
But if we talk about the IQ floor...
He dared to guarantee to everyone that this person must be Shancun Cao.
A mountain village student whose IQ has reached the lowest limit.
Although this was not the first time that Makoto Sakaki was suspected of being a criminal, this was the only time he had ever seen such an outrageous suspicion.
Mountain Village Fuck....
It's not playing by the rules at all!
Who can keep up with his way of thinking?
But in other words...
He is also very easy to fool.
Sakaki Makoto didn't want to waste time, he said directly:
"Inspector Yamamura, I am not the criminal."
"Eh? Isn't it you?"
Yamamura Cao blinked:
"But your fingerprints are the only ones on the stove that produces carbon monoxide!"
"That's because I just brought the stove into the room, and of course my fingerprints are on it."
"Hmm... makes sense."
Yamamura Cao was convinced by this reason.
"Inspector, you can't trust him!"
The slightly smarter police officer behind him saw that the boss was about to be fooled again, and hurriedly reminded him:
"Although we can't prove what he said, he also can't prove his innocence!"
"Why can't his fingerprints be left on the stove when he committed the crime?"
"Oh, yes!"
Yamamura So's eyes lit up, and suspicion of Sakaki Makoto suddenly surged in his heart:
"How do you prove that you are not a criminal?"
"Inspector! This is our duty. We shouldn't question the suspect!"
The police officer was really worried and felt helpless about this incompetent boss.
Sakaki Makoto and Kidd looked at each other, unable to describe how desperate they were.
This kind of person...
Isn't it just to hinder them from solving the case? !
It seems that the Gunma Prefecture's forensics department is quite capable and immediately identified the source of the carbon monoxide, which was somewhat beyond Sakaki Makoto's expectations.
From the police's perspective, all members of the Ogawa family were poisoned by carbon monoxide, except for Makoto Sakaki and Kidd, so it was understandable to suspect them, so before finding the identity of the criminal....
Sakaki Makoto must first prove his innocence so that he can get rid of the entanglement of Dacongming Shancuncao.
first....
"Inspector Yamamura, please answer me, whose call did you receive? And why did you rush to the crime scene so quickly?"
Less than 10 minutes have passed since Miss Miyano and others were poisoned by carbon monoxide. The reaction speed of the Gunma Prefecture police is not so much swift as it is prophetic, foreseeing that a gas attack would occur here in advance.
"Call the police?"
Shancuncao was stunned for a moment:
"I don't know who called. The other party used a voice changer and the number was hidden."
"When did you receive the report?"
"It should be 9:55. I was eating instant noodles when the phone rang. Someone said there was a case of carbon monoxide poisoning here..."
9:55?
Miss Miyano and the others were poisoned at exactly 10 o'clock, which means...
Someone called the police 5 minutes in advance.
"The one who called the police is the criminal."
Sakaki asked Kid to show the call records on his phone and said:
"We found someone suffering from carbon monoxide poisoning at 10 o'clock and called the hospital's emergency number in time. When the police received the report, the criminal had not yet committed the crime. Do you understand?"
Shancun Cao asked in confusion:
"The prisoner called the police himself? Why?"
"Because the death time from carbon monoxide poisoning is 15 minutes."
Shaking his head, Sakaki Makoto explained:
"In a closed environment with high carbon monoxide concentration, if the patient does not receive timely treatment, it will only take 15 minutes for him to die from respiratory failure."
"The carbon monoxide content in the atmosphere is only 0.002%, and the carbon monoxide concentration that humans can withstand is 0.005%. When a carbon stove burns, the carbon monoxide concentration in the air can rise to 6%-30% in a short period of time, far exceeding the human limit."
"The reason why the criminal called the police in advance was because he didn't know that we went out just when the carbon monoxide concentration in the house was rising. In the criminal's plan, everyone would be killed. At this time, the police who received the report in advance rushed to the scene and could launch a rescue before the criminal died!"
"Souga! I see!"
After slapping his head, Shancuncao understood:
"That prisoner is really clever! But why did he allow himself to be poisoned?"
"To get rid of suspicion, of course!"
Gritting his teeth, Sakaki Makoto resisted the urge to hit the man and said angrily:
"Just like you are suspecting me now, whoever is not poisoned at the crime scene is the biggest suspect, right?!"
"Hmm, that makes sense..."
Yamamura So didn't hear the anger in Sakaki Makoto's tone at all. Instead, he thought seriously:
"We received the report at 9:55. It took 13 minutes to get here from the police station. The carbon monoxide poisoning incident occurred at 10 o'clock. Including the time to call the ambulance, there was still 5 minutes to spare. It was a brilliant plan, but..."
"Whether you are poisoned or not, the police will arrive at the scene in time. In this way, the criminal's plan will be thwarted, right?"
"You only know one side of the story but not the other."
Sakaki Makoto said with a sullen face:
"The affinity of carbon monoxide for hemoglobin is 240 times that of oxygen! Once it enters the human body, it will quickly combine with hemoglobin, causing the body to be short of oxygen. The patient will experience symptoms such as unconsciousness, dizziness, and coma. Long-term lack of oxygen will cause irreversible damage to the brain. It's okay for young people, but it will become very dangerous for the elderly!"
"Among the poisoned patients, there is an old man named Yoshio Ogawa. He suffers from Alzheimer's disease, brain atrophy, and epilepsy. The lack of oxygen in the body may not be fatal to us, but it is different for him!"
"In the final analysis, the criminal's goal was not to kill us, but specifically to target Ogawa Yoshio!"
That’s all I have to say. Whether you can understand it or not is up to Shancuncao himself.
Shancuncao thought for a moment, then looked at his subordinate beside him and asked with his eyes.
"Yes, Inspector. There is indeed an old man named Ogawa Yoshio in the Ogawa family. We can find out the details with just a little investigation. I don't think he would dare to make up stories."
The subordinate gave an affirmative answer, proving that what Sakaki Makoto said was true.
"So it seems that you are not the criminals..."
Shancuncao finally came to his senses:
"It was you who called the emergency number. Without your help, I'm afraid Ogawa Yoshio wouldn't have had a chance to be saved..."
“You finally understand.”
Sakaki Makoto nodded, feeling slightly relieved.
fine.
Fortunately, although Shancuncao is a little stupid, he can at least communicate and listen to reason. He is not the kind of stupid person who likes to act on his own.
"So who are you? Why are you here at the crime scene?"
"....We are friends of Yoshio Ogawa. We came all the way from Tokyo to visit him."
"Tokyo?"
Shancun Cao was surprised:
"So do you know the Great Detective Maori?"
