In Conan, people have a brain option system.

Chapter 179 Verifying the conjecture (12)

Akikawa Sousuke's "inadvertent" words instantly awakened Conan and Sera Masumi, who were trapped in a dead end due to their refusal to cooperate.

What puzzled the two detectives the most in this case was the reason why Kunio Koizumi wanted to cover up the deceased Kawasaki Ryo's computer posture.

After all, Kosenan is a hot spring hotel for vacation.

Everyone's first reaction was that Kawasaki Ryo came here for vacation.

However, when they learned that this hot spring hotel was not only popular among programmers,
Then the nature is completely different.

"Mr. Kawasaki is not here on vacation at all."

"As a senior programmer at a large IT company, the reason why he stayed at home for so many days after coming to Guquanan is probably because he was working overtime to develop software!"

"The description of the staff who delivered the meal earlier also confirmed that Kawasaki Ryo was not able to rest properly after arriving at Kosenan."

"Some reason must have led to Mr. Kawasaki's death, and Mr. Koizumi didn't want the fact that Mr. Kawasaki developed software to be exposed, so he had to dismember Mr. Kawasaki while he was still using a computer."

"After all, for ordinary people, they don't know the connection between this and programmers at all."

"So as long as the police don't know that Mr. Kawasaki was using a computer when he died, they will naturally not investigate the software he developed."

After figuring out all of this, Masumi Sera turned to look at Inspector Okamura standing beside him.

"Officer Okamura, could you please investigate Mr. Koizumi's previous occupation?"

"I think that since this hotel is so popular among programmers, there must be other reasons besides the fact that the hot springs here can heal the body and mind."

“——The reason why a group of programmers can gather here.”

Inspector Okamura was about to give his orders when he heard Kunio Koizumi slowly speak:

"No need to check. Before I started running a hot spring hotel, I was also a programmer."

This time, Kunio Koizumi's tone was no longer as firm as before, but was filled with despair.

He originally thought that after he dismembered Kawasaki Ryo, the police would not be able to link Kawasaki Ryo's death to the computer no matter what they did.

Unexpectedly, the high school detective figured out so quickly that he was using dismemberment to cover up the posture of Kawasaki Ryo's death.

Kunio Koizumi wanted to stop the police from continuing their investigation by confessing his guilt.

It’s a pity that the artist Akikawa Sosuke, who suddenly appeared from nowhere, provided the detective with the most important information with just a casual remark.

When Kunio Koizumi heard Sera Masumi's reasoning, he knew that he could not hide it any longer.

Because once the National Police Agency makes Sera Masumi's reasoning public, everything will be over.

"So, could you please repeat what happened yesterday in full?"

Inspector Okamura added.

Koizumi Kunio nodded desperately and said:
"Yesterday, I finished taking a statement at the police station, and after returning to Kosenan, I found out that Kawasaki had been murdered."

"You didn't kill Mr. Kawasaki?!"

The police officers present all showed extremely surprised expressions after hearing what Kunio Koizumi said.

In their minds, the moment the forensic police confirmed that there was a large amount of blood in Kunio Koizumi's bathroom, they had already equated him with the murderer.

"Who killed him then? And how did he die?"

Inspector Okamura asked further questions.

"…not sure."

After hesitating for a moment, Kunio Koizumi gave an ambiguous answer.

"But Kawasaki should have died from a knife wound to the neck."

"A knife wound on the neck? But I didn't see any knife wound on Mr. Kawasaki's neck."

A detective said in confusion, "Because Mr. Koizumi covered up the wound by dismembering the body."

Sera Masumi said.

The police officers present all showed slightly horrified expressions when they heard this.

Before Sera Masumi explained, they had never imagined that there could be such a cruel and cruel method.

And Kunio Koizumi's description once again verified Akikawa Sousuke's guess.

When Akikawa Sosuke discovered at the beginning that the victim's neck was the only part that was not cut through the movable joints, he guessed that the dismemberer might have wanted to use the cuts to cover up the fatal injury caused by the real murderer.

Assume that the dagger was stabbed into the victim's neck in a horizontal position.

Then when dismembering the body, just cut along the wound location, and the original wound will be covered by the larger "complete neck separation" wound.

It’s just like what Ohkawa Takao did before, using gunshot wounds to cover up the injection needle holes.

However, the police raised new doubts.

"No matter how serious the wound on the neck is, it can't kill him instantly, right? How could the deceased maintain the posture of using the computer in this situation?"

"If it is an important blood vessel such as the carotid artery or jugular vein, then in extreme cases, death may occur within 1-2 minutes."

"Assuming that Mr. Kawasaki was stabbed in a vital part, or had lost consciousness when he was stabbed, it is possible that he was in the position of using the computer."

As Sera Masumi said this, he stole a glance at Akikawa Sousuke's neck at the door.

There, too, is a scar.

That was the scar left by Akikawa Sosuke when he was stabbed with the dagger that the murderer of the car accident killed his mother with more than half a month ago.

If Akikawa Sosuke had worse luck, he would probably have died at that time.

Masumi Sera withdrew his gaze from Akikawa Sosuke and continued to look at Kunio Koizumi.

"So, what exactly is the software you and Mr. Kawasaki developed? And why would you rather dismember your friend than call the police?"

"Because...if the police knew about this, my family would be in danger."

Kunio Koizumi once again made a shocking statement.

Kanagawa Prefecture's police chief, Bu Okamura, was stunned for a moment, then suddenly said angrily:

"Are you being threatened, Mr. Koizumi?"

"How can you not trust the police?"

Upon hearing this, Masumi Sera and Conan looked at Inspector Okamura speechlessly.

This man was about to take Koizumi Kunio to the police station as a criminal just a few minutes ago, but he still had the nerve to say this at this time.

Kunio Koizumi turned his head and glanced at Inspector Okamura, and said coldly:
"If it weren't for this detective, would you be able to determine the truth?"

Inspector Okamura blushed and said awkwardly:

"Of course... we can! It will just take us a little longer, but as long as we carefully check the surveillance footage, we will definitely be able to catch you, Mr. Koizumi."

"But you would never know that Kawasaki was using a computer when he died."

After saying this, Kunio Koizumi sighed.

"Anyway, this is what happened. I was the one who dismembered the body. I also destroyed the fatal wound on Kawasaki's neck. You can't get any evidence."

"Just think of it as me who killed Kawasaki and take me to the police station."

"When I face the prosecutor and the judge, I will also say that I killed someone, so you don't need to continue investigating."

"If the truth gets out, my family will die."
