In Conan, people have a brain option system

Chapter 165 The murderer is you——(12)

The three suspects, Kyusuke Akikawa, Mayumi Motoki and Shoichi Matsutani, stayed on the first floor of Kosen-an under the surveillance of the criminal police.

Mayumi Motoki and Shoichi Matsutani were obviously full of hostility towards Akikawa Kongsuke because of his "slander".

But Akikawa Kyusuke didn't care about this.

He sat on the chair and ignored the glares of Mayumi Motoki and Shoichi Matsutani.

Quietly observing the actions of the criminal police at the scene.

About ten minutes later, a criminal police officer came back carrying a black suitcase.

Then the police from the Forensic Division began to search for fingerprints on the suitcase.

‘The suitcase used to dump the body was found. ’

Akikawa Kyousuke thought in his heart, and then looked at Shoichi Matsutani and Mayumi Motoki.

Then it was discovered that the two of them did not show the slightest panic because the police found the suitcase.

After more than twenty minutes, a criminal policeman came down from upstairs.

Then he went straight to the souvenir sales area on the first floor of the hot spring hotel, and then picked up the bath agents sold there and inspected them.

After a while, the criminal policeman came to the staff of Guquan Temple with the bath agent in his hand and began to ask them what they were talking about.

However, when faced with the criminal police's questioning, several staff members shook their heads and showed blank expressions.

Unlike when the suitcase was discovered by the criminal police,

This time, after seeing the detective approaching the staff of Kosen-an with a bathing agent,

Mayumi Motoki and Shoichi Matsutani both showed signs of dilated pupils and slight movements of their lower lips pursed.

This scene could not escape Akikawa Kyousuke's eyes.

He knew that this was body language that represented anxiety and tension.

In addition, Akikawa Kongsuke also noticed that both suspects had tight cheek and jaw muscles.

So Akikawa Kongsuke had a further judgment on this case.

'Both of them showed nervousness and anxiety about the bathing agent, so it seems that they used the bathing agent of Kosenan to make hydrogen sulfide to kill Takeshi Furusawa. ’

'They were very confident in the handling of the suitcase used to throw the body, and they thought there were no flaws in it. ’

'However, the two of them obviously did not expect that the criminal police would so quickly target the bath agent as a raw material for making hydrogen sulfide. ’

‘If it hadn’t been for the Shinigami pupil, maybe the police would have been deceived. ’

Akikawa Kousuke previously confessed to the police that he heard Motoki Mayumi and Matsutani Shoichi secretly discussing matters about Furuzawa Kenshi. This was indeed Akikawa Kousuke's nonsense.

However, the two of them could not prove that Akikawa Kyusuke was lying.

Because Mayumi Motoki and Shoichi Matsutani did know each other, and they were indeed accomplices in killing Takeshi Furusawa.

Akikawa Kyousuke only had a brief contact with the two when he was called down by the police for questioning, and he judged this.

He noticed that when Mayumi Motoki heard Furusawa Takeshi's name, she had a slight change in expression with the corners of her mouth turning downwards and one of her eyebrows raising.

This means that Mayumi Motoki hates the name Furuzawa Takeshi in her heart.

This conflicts with her confession that she did not know Takeshi Furuzawa.

Akikawa Kyousuke also noticed that when Mayumi Motoki was regarded as a suspect by the police because she did not have an alibi at one o'clock in the middle of the night,

He once refuted the police with "Most people are sleeping at this time, how can we have an alibi?"

When being regarded as a suspect, it seemed very strange for Mayumi Motoki to use "we" to refute the police.

If the case really had nothing to do with her, it would be more beneficial to her if the other suspects were suspected by the police.

She had no reason to explain for the remaining suspects.

Unless there is someone who knows her among the suspects.

After Mayumi Motoki made this speech, Shoichi Matsutani immediately took over and expressed his agreement.

This made Akikawa Kongsuke suspicious of the relationship between the two.

In addition, Shoichi Matsutani glanced at Mayumi Motoki many times when she was speaking.

But after the two of them made eye contact, Shoichi Matsutani would always look away immediately.

Akikawa Kyousuke judged from Matsutani Shoichi's behavior of deliberately avoiding eye contact that he wanted to hide the fact that he and Motoki Mayumi knew each other.

This method of judging what the other person is thinking by relying on micro-expressions and psychology cannot be 100% accurate.

But when many of the other party's behaviors point to the same conclusion, then that conclusion is most likely the truth.

Many of the performances of Mayumi Motoki and Shoichi Matsutani point to the fact that the two are deliberately hiding the fact that they know each other.

And Mayumi Motoki, who seems to have nothing to do with the case, is also hiding her dislike of the deceased Takeshi Furuzawa.

Therefore, Akikawa Kongsuke judged that this could not be just a coincidence.

The two most likely collaborated to kill Furusawa Takeshi.

The perpetrator was Shoichi Matsutani, who apparently had no motive for killing Takeshi Furuzawa.

The person responsible for providing Shoichi Matsutani with the tools to commit crimes is Mayumi Motoki, who does not seem to have the ability to commit crimes.

Akikawa Kyusuke is not a policeman or a detective.

He didn't need to catch the criminal himself, so he didn't need to find out the criminal's motive and method of committing the crime.

There was no need to find solid evidence that could identify the other party as the murderer.

Akikawa Sosuke only deduced that Matsutani Choichi and Motoki Mayumi were the criminals from their words and deeds.

After revealing this matter to the Death God Elementary School Student, Conan would naturally complete all the remaining steps.

After so many contacts with Conan, Akikawa Sosuke found that this little detective had a strong ability to find evidence after determining the murderer in advance.

Sure enough.

After Conan began to suspect Motoki Mayumi and Matsutani Choichi because of Akikawa Sosuke's words, he quickly searched for the bathing agent, a seemingly inconspicuous murder weapon, from the other party's room.

Akikawa Sosuke was thinking in his heart, and saw Conan and others coming down from upstairs.

Dr. Agasa, who looked extremely smart, came to Akikawa Sosuke and others, and said under Conan's voiceover:

"The murderer's method of committing the crime has been completely understood."

"The murderer used the bathing agent sold by Kosen-an to make hydrogen sulfide gas, and then used the mask of Kamen Rider to kill Mr. Furusawa."

"The murderer is you--"

"Mr. Matsutani!"

"And you, Ms. Motoki, assisted Mr. Matsutani in completing the murder."
