Conan: Chief of Rice Flower's Science Points

Chapter 103 Resonance
Kanzaki, who had been staring at the "scene" but didn't notice any changes, frowned and asked, "Are you sure it was this music?"

"Yes, this is my famous song "Kizuni"..." Fujimaru quickly confirmed.

Akasaka, who was focusing on the "person", noticed that Fujimaru Yoshino's face had turned ugly, so he interrupted and asked, "Mrs. Fujimaru, have you thought of anything?"

"No, nothing..." Fujimaru Yoshino hurriedly shook his head.

But just as Akasaka frowned, Fujimaru Yoshino emphasized: "This was... created by me and my husband when I was an assistant."

Akasaka:……

Everyone in the room looked at Fujimaru Kazuo with disdain - he was singing under the wedding photo, and using the famous song they created together to cover up the sound... Was this to make his wife feel more involved?

At this moment, Kanzaki suddenly discovered something in front of the console, pointed at a very low volume control fader and said, "Is this also a channel?"

"That's right, but that one is empty..." Seeing this, Fujimaru Kazuo nodded disapprovingly.

but……

Kanzaki didn't care whether it was empty or not at this time, but directly pushed this channel to the highest level, and turned off all other channels at the same time.

There was indeed no other sound afterwards. Instead, the place became quiet again because the other sound channels were turned off. However, Bai Shi's expression tightened a little at this time, and he stretched out a finger and scratched his eyebrows.

Kanzaki frowned and said, "Did you feel it..." As he spoke, he gestured next to his ear, as if he heard something faintly.

"Huh? What's wrong?" Akasaka said puzzledly.

at the same time……

Kara - Kara -

There really were some strange noises around, and... the source of the sound was the photo frame that Bai Shi had just hung up!

"What, what's going on?" Akasaka was stunned when he saw this.

At this time, Shinichi and others also came up.

"Hmm?" Akasaka looked at Kuroki, as if wanting to ask him what was wrong.

"Kudo and the others said they seemed to hear some sound...could it be an illusion?" Kuroki was also wondering at this time.

But just then...

click-

There was a loud bang, and the photo frame that Bai Shi had just hung up suddenly shattered by itself!
Fortunately, everyone had already sensed that something was not right and had moved away from it.

Looking at the thick glass shattered all over the ground, everyone had no doubt that if there was really someone underneath, he would be injured if not dead!

Shinichi curled his lips in dissatisfaction upon seeing this - as expected, Shiraishi not only discovered the murderer's flaw, he even knew the method!
only……

Seeing Kanzaki pumping his fist in celebration at the control console, Shinichi finally understood something.

It seems that Shiraishi was not prepared to tell the truth from the beginning. The reason why he sent me away was to create opportunities for his police officers!
"Kami, Kanzaki, what's going on? How did you do it?" Kuroki asked in surprise.

"Resonance! It's resonance!" Kanzaki said excitedly - those who didn't know would think that he discovered the physical phenomenon of "resonance".

"Resonance?" Kuroki's eyes sparkled with clarity.

"Elastic objects are more sensitive to vibrations of a certain frequency. Once affected by this frequency or vibrations close to this frequency, they will produce large vibrations... Audio that meets the inherent frequency of the photo frame glass has been added to this music, so when it plays to a certain stage, the glass will shatter!" Kanzaki explained.

"Audio? What audio?" Hei Mu still didn't understand.

"When people are young, they can hear sounds up to 20,000 Hz. However, as they age, this upper limit will continue to decrease... This sound should be around 20,000 Hz. These three students must have heard some of it, right?" Kanzaki looked at Kudo and the other two.

Among the people present, apart from the three sixteen-year-old high school students, Ryuichi Kanzaki was the youngest, only 22 years old, and his hearing was very good, so after turning up the volume, he and the three students from Teitan High School could vaguely hear some mosquito sounds.

"I see. In short... it was the music that caused the photo frame to break?" Akasaka skipped the conclusion and looked at Fujimaru Kazuo.

"No... I haven't added any such thing! And... I play this music every time, and I haven't found that it would cause anything before..." Fujimaru Kazuo quickly denied it.

"That should be... someone else who knew you would play this disc during your affair, and modified the audio. If you investigate this kind of thing, you will easily find clues." Kanzaki said, looking between Fujimaru Kazuo and Fujimaru Yoshino. He was not sure who it was, and he did not speculate too much about the psychology of the "involved persons". To him, the two couples were equally suspicious, and he only focused on the physical evidence!

However, after the discovery of the "resonance" mechanism, there was no need for any other reasoning - as long as the fingerprints on the console and disc, as well as the modification records, were thoroughly investigated, the murderer would not be able to hide at all.

Just then...

Yoshino suddenly fell to his knees and said, "No need to check... Of course you'll find out it's me!"

Seeing this, Fujimaru Kazuo immediately became alert: "What? It's you, a vicious woman?"

"Vicious? Back then...wasn't it me who first composed your famous song?" Yoshino said angrily.

"Shut up! W-what did you create? Even if you provided some ideas at the beginning, it was me who completed it in the end..." Fujimaru Kazuo said with his neck stiff.

"Yes, at that time I thought it didn't matter even if it was like this. After getting married I even gave up my music career, but I didn't expect..."

Yoshino was already very angry at this time, and recalled the words that Hideko mocked her when she went to persuade her to leave. She believed that she had a deep "bond" with her husband and a legal marriage, but... her husband chose to have an affair in "Bonds" and under the "wedding photo".

At this moment, Yoshino suddenly stood up, holding a large piece of glass in his hand, and was about to stab Fujimaru Kazuo in front of him!

but……

Of course she won't succeed.

A big hand reached out from behind her, over her shoulder, and grasped her hand holding the glass shards.

"Madam, please don't add more sins." Bai Shi said calmly.

In terms of size, Fujimaru Yoshino, who is less than 1.6 meters tall, is no bigger than a child in front of Shiraishi. Looking from a "high vantage point", he can see everything Shiraishi does clearly.

"Killing two people is completely different from killing one person. Using the love song that you and your husband wrote together to verify revenge and cause the death of the adulterer is completely different from intentionally killing someone with a weapon." Shiraishi continued calmly.

Seeing this, Akasaka hurried forward and snatched the glass fragments from her hands, and handcuffed her.

"What verification? Director Shiraishi, this is the deliberate murder she has been planning for a long time, right?" Fujimaru Kazuo said immediately.

"Who knows... The identification of murder requires the unity of subjective and objective factors, while the identification of premeditated murder requires the unity of behavior and consequences. If you had told the suspect that you would continue to have an affair with this music, then it would undoubtedly be premeditated murder.

"If you have promised not to have an affair again, the prosecutor or the lawyer may also think that this is a test, that is, using dangerous means to see whether you can keep your promise, and thus causing the death of the victim... Well, the specific sentence and how much responsibility you each have to bear depends on the situation in the court." Shiraishi said with a shrug.

Anyway, the Mihua Police Department will record the incident truthfully and send the case to the prosecutor for murder. As for how the prosecution will attribute the crime, how the defense lawyer will argue in court, and how the judge will exercise his power to judge... that is not the Mihua Police Department's business.

At the same time, after being stopped by Shiraishi and handcuffed, Yoshino calmed down a little. She did not fight with her husband again, but said fiercely: "Fujimaru Kazuo...just wait and see! Our 'bond'...I will explain it clearly in court!"

"You..." Fujimaru Kazuo panicked when he saw this.

As a composer, he is a public figure after all, and his compositions have always been mainly love songs, not rock music. If such things were exposed by reporters, especially if he had to argue in court about whether his wife knew that my promise not to cheat was a lie, his reputation and future would be in jeopardy.

"Mr. Fujimaru Kazuo, please come to the police station later to explain clearly about the destruction of the crime scene and the impact on the investigation of the case." Akasaka also had a long face at this time.

Although this guy is not the murderer, but...

Because he despises the person, Akasaka of course chooses to deal with the matter seriously as it "can be investigated or not"!

Both of them were taken into the police car, but the three people from Teitan High School were not in a hurry to be taken away to take a statement. After all, it was already late at night.

Since the criminal had been arrested, Shiraishi certainly had no intention of going to work early tonight. He just saw Akasaka and the others off.

While Ayako was talking to Sonoko, Kudo Shinichi approached Shiraishi unconvinced and said, "Director Shiraishi, when did you think of the criminal... no, when did you think of the murder method?"

Shinichi felt that since the criminal this time didn't kill people often, he still had a lot of emotional holes, but... this method had troubled him for a long time.

Finally, he remembered that when Yoshino first arrived at the scene, he operated the audio console while everyone was looking at the body. Then he thought of the broken photo frame downstairs, and inspiration suddenly hit him.

But Bai Shi didn’t see this scene!
This made Shinichi feel the same frustration and unwillingness as when he was in the aquarium...
