Chapter 210: Akikawa Sosuke's Abilities (22)

"It wasn't through any clues or special information that they determined Chianti was the murderer, but through my reaction..."

After listening to Akikawa Sosuke's explanation, Sera Masumi was also shocked.

She originally thought that Akikawa Sosuke was deceiving her.

In fact, Akikawa Sosuke already had clues about the real murderer.

But she really didn't expect that Akikawa Sosuke could link the murderer of his mother with the person who had a deal with Koizumi Kunio based on just a few questions she asked him that day.

This keen sense of intelligence and observation of people is simply terrifying.

"So, Mr. Sera, what is the matter that brought you to see me today?"

Akikawa Sosuke put the cup in his hand on the table and asked Sera Masumi while looking at him.

"I have a few questions for Mr. Akikawa."

Sera Masumi came back to his senses and spoke slowly.

"I originally wanted to ask Mr. Akikawa how you knew that Chianti was the real culprit in the car accident."

"But you have already given an explanation just now, Mr. Akikawa."

Sera Masumi said with a smile.

She suddenly had a premonition.

Perhaps Akikawa Sosuke is much better than he and Conan expected.

She then asked:
"Mr. Akikawa, how did you know the time of the transaction between the organization and Mr. Koizumi?"

Masumi Sera asked Akikawa Sosuke the question that he was most curious about.

She discussed this with Conan.

Because it is impossible for anyone on their side to leak the information.

So Conan concluded that the information was leaked by the organization.

"If Qiuchuan really got this information from the organization, then the source of his information may become a breakthrough for us to fight against the organization."

Masumi Sera was expecting this in her heart.

Then she heard Akikawa Sosuke say:

"Please don't expect too much from me. I know almost nothing about that organization."

Masumi Sera, whose thoughts were revealed by Akikawa Sosuke's words, was suddenly stunned.

'How...does he know what I'm thinking...?'

While Sera Masumi was horrified, he quickly asked:

"Impossible! This information should only be known to me and Mr. Koizumi."

"Mr. Akikawa, you obviously knew the time of the transaction between the organization and Mr. Koizumi, so you made preparations in advance."

Kunio Koizumi originally planned to make a deal with the organization in the early morning of the day after the dismemberment case. He told this to Masumi Sera and Conan alone at the time.

This is top secret information.

Masumi Sera believed that Akikawa Sousuke, who knew this information, must have other ways to obtain information about the organization.

"This is the same reason why I concluded that the woman with the tattoo on her left eye was the murderer of my mother."

"No special means or channels are needed. I just determined this by analyzing Kunio Koizumi's behavior."

"How can this be!"

Upon hearing this, Sera Masumi couldn't help but raise her voice.

She felt a little unbelievable.

After he came out of the monitoring room, he went straight to Akikawa Sosuke to ask about him and his mother being hunted, so Akikawa Sosuke noticed something was wrong.

Although this matter was quite unbelievable, Sera Masumi felt that he could still understand it.

however.

Akikawa Sosuke had only seen Koizumi Kunio for a few minutes when he was brought to the door of Koizumi Kunio's room.

The two of them had never even spoken face to face.

How could Akikawa Sosuke know the time of the transaction just by analyzing Koizumi Kunio's behavior?
These should be two completely unrelated things!
"Because of dismemberment."

Akikawa Sosuke said softly.

When Sera Masumi heard this, a look of confusion appeared on his face. "Mr. Kawasaki has fallen into rigor mortis while still using his computer."

"Because Mr. Koizumi wanted to conceal this, he dismembered Mr. Kawasaki."

"Yes."

Sera Masumi nodded.

These are all things she deduced herself, there is nothing wrong with them.

"Mr. Kawasaki died the day before the dismemberment case, which was the day the poisoning case occurred."

"Because of the poisoning murder that happened that morning, the police were called in."

"So the murderer had only the time between when Mr. Koizumi was taken away by the police to take a statement that morning and when he returned from taking the statement that evening."

"Since Mr. Koizumi found that Mr. Kawasaki had already developed rigor mortis when he returned, it means that Mr. Kawasaki had been dead for at least 7-8 hours."

"Then Mr. Kawasaki must have been killed around noon on the day of the poisoning."

Masumi Sera nodded as he listened to Akikawa Sosuke's story.

It was only after watching the surveillance video that she was able to determine the time of Kawasaki Ryo's murder was between 13:17 and 13:29 on the previous day.

Unexpectedly, Akikawa Sosuke was able to pinpoint the time of Kawasaki Ryo's murder to a similar range just by hearing a brief description of the case.

Of course, this is not difficult.

As long as we know the time when rigor mortis occurs, we can make such an inference.

She still didn't understand what this had to do with the timing of Koizumi Kunio's deal with the organization.

Then she heard Akikawa Sosuke continue:

"Rigor mortis usually lasts 24 to 48 hours."

"Based on the temperature at the time, rigor mortis should have started to subside about 40 hours after it occurred."

"In other words, if Mr. Koizumi only wanted to cover up the posture of Mr. Kawasaki's death, there was no need to go to the trouble of dismembering the body."

"But if Mr. Kawasaki's body produces a stench, won't it be exposed?"

Sera Masamune asked in confusion.

However, as soon as she asked the question, she realized the problem.

Then I heard Akikawa Sosuke continue:
"Perhaps it is difficult for someone to cover up the stench of a corpse in a hot spring hotel where they are staying. After all, overly strange behavior can easily arouse suspicion."

"But Mr. Koizumi is the owner of Kosen-an, and the room he lives in is his own room, so no one can enter his room unless he asks."

"It should be much easier for him to cover up the stench of a corpse in his room for 40 hours than to dismember Mr. Kawasaki."

"But Mr. Koizumi has no reason to do this. I think there is only one reason——"

"That's when he can't wait for rigor mortis to subside on its own."

Akikawa Sosuke's voice was not loud, but it sounded like thunder to Sera Masumi's ears.

She was stunned on the spot for a moment.

Masumi Sera is smart enough.

When she heard this, she completely understood what was going on.

"Mr. Kawasaki was killed at noon on the day of the poisoning case. 40 hours later, on the morning of the day after the dismemberment case, his rigor mortis should have almost subsided."

'Mr. Koizumi tried to take the blame for Mr. Kawasaki's murder on behalf of the real murderer in order to protect his family.'

'He couldn't wait for Mr. Kawasaki's body to break down, so he had to dismember it.'

"Therefore, the time when Mr. Koizumi and the organization's people made the deal must have been before the morning of the day after the dismemberment case."

"Then the time available for Koizumi-san to negotiate with the organization is only between the night of the dismemberment case and the early morning of the next day..."

With a look of shock on his face, Masumi Sera completed Akikawa Sousuke's subsequent reasoning in his mind.

"There are no clues, no direct evidence, no surveillance, and no face-to-face conversation with Kunio Koizumi."

"With such little information, he was able to foresee what would happen next just by looking at the dismemberment of Kunio Koizumi?"

"This man's ability is simply..."

Masumi Sera raised her eyes, which were trembling with shock, and looked at the thin artist opposite her who picked up the cup again and drank coffee through a straw.

There was a huge storm in my heart.
