Hearing Okata's words, Xiaolan walked to the open window and pressed the switch of the speaker.

Everyone looked at Okata because the protagonist was him at this moment. Everyone's thinking was in the inference of this case, following every word he said.

"If you look closely, you will find that the books on the desk are slight shaking, and a medium is formed between the desktop and the desktop. Through this subtle oscillation, listening to the little bones will feel a stream of low audio. This low audio generates more sound pressure, causing another uncovered ear to receive higher audio."

"That is to say, after the sound is turned on, the disc played by Mrs. Damura is a 'Black Sunday' as a forbidden song. And through what I explained just now, the biggest difference between this song and other melodies and rhythms is that there will be a significant upscaling in the change of rhythm, causing high audio to press the human heart. In this confined space, the sound is gathered, and we can see in the study that the desk that can form a resonance principle with the music under the same volume state is the desk used by the deceased to support the elbow and maintain a stable sitting position."

"The desk was shocked by sound, which caused the deceased's elbow to receive the transmission of this medium and reflected the ears covered by his body. The audio received by this ear caused a certain low-sounding sound pressure, and at the same time, the high-frequency syllables were refracted in the other ear, causing the pressure applied to the deceased's heart to be maximized. A total of 13 ups and downs, each rise was tantamount to a heavy hammer on the deceased's chest, causing his heart to atrophy, cramped, and nervous. Finally, there was a sudden stop in the myocardial function under severe contraction and damage."

Okara stood up, his eyes swept across everyone's eyes. With a calm expression, his lips gently opened, and his voice swept away all the doubts and confusions in the study.

Hattori Heiji looked at him, and when he thought of his previous contempt for him and his behavior of interrupting his autopsy, his expression became awkward.

After hearing the final answer, Kudo Shinichi finally felt relieved.

Cousin, it's him again.

Although he didn't want to admit it, he lost to his cousin in such a situation where there was almost no reason to argue.

Even as Shinichi Kudo, he appeared in front of him.

"But Brother Ogata, although the process of the case has changed, Mrs. Tamura cannot clear her murderous crime." Megu sighed and directly expressed her thoughts.

He was determined to help the mother and daughter, but the facts were analyzed and interpreted after Okata's inference. However, she put the disc into the machine and played on the audio, so she still couldn't clear her guilt.

When Okabaya heard Meguchi's words, he smiled softly: "Police Department, as a diplomat, Tatsumura Mori, in order to take into account his reputation, how could he collect such banned songs? Even if he has a hobby of collecting, he would not place discs like 'Black Friday' on the surface."

"you mean"

There was a hint of surprise in Memu's eyes, and he knew that Okara had something else to say.

Okabaya said lightly: "Mrs. Tamura is unavoidable to be criminally responsible, but her crime can be reduced because from a legal perspective, the person who gave the disc to the deceased was also the one who gave the disc to the deceased."

Kogoro Maori said in confusion: "Are you saying that this disc did not originally belong to the deceased, but someone attempted to murder him?"

If there is really a deceased person in this process, a third person other than Mrs. Damura, then the judgment will be completely different.

"It can be understood this way." Okabaya walked to the speaker in the window, opened the machine storing the disc, took out the disc with the ban song "Black Friday" and said, "This disc was deliberately designed by someone to let the deceased hear it. Because the 'Black Friday' song is a gentle and ordinary symphony before the music about 8 and a half minutes, and it is the same behind it. So the person who took the disc to the deceased to move was holding a grudge. He obviously knew the background and information of the three ban songs. Copy the music into the disc and mixed it between other symphony music. I hope to use this song to curse him to die sooner."

Upon hearing this, Memu nodded: "In other words, the person who gave the deceased to hold a grudge against him for some reason. So I hope to use a music like "Black Friday" that can make people commit suicide, curse Tamura Tou to die early, but I didn't expect it to eventually turn into reality."

"So who is the person who gave this disc to the deceased?" Megu never left Okata, because the progress and inference of the entire case were led by him.

Okao searched the forensic doctor in the department and overturned the reasoning of high school detective Shinichi Kudo, making Meguri feel good now.

Because before he appeared, the police would use the words "detective XX" in each newspaper to describe the cracking of a case. Although it improved the police's efficiency in solving cases, it was a disguised saying to the people of society that the police are so incompetent and need to rely on detectives to help.

Seeing that Mrs. Tamura's expression and expression were relieved a lot, Okata asked: "Madam, do you remember that in recent times, have you received express delivery and email?"

"Email?" Mrs. Tamura looked at Okamaru gratefully, and then thought hard.

After a long time, she replied: "I remember that the butler Xiaochi walked into the study with a file bag a few days ago. I caught him at that time and said that he had something to discuss with Dacundong. But as far as I know, Dacundong went outside to meet customers at that time, but he was not in the study."

Hearing Mrs. Dacun's words, who had been ignored and stood in the corner without saying a word, the butler Xiaochi Wenxiong turned pale and looked at everyone's eyes in panic.

He knew that because of Mrs. Damura's remarks, he had now become the target of suspected murder.

Fumio Koike hurriedly explained: "I was holding the documents that Mr. Tamura wanted to process, not a disc."

Ogata looked at the butler who gave people a sense of stability at first sight. He did not ask about the file bags and discs in detail, but instead changed the topic: "Mr. Koike, how did you and Mr. Tatsumura meet."

Koike Fumio was stunned and looked at Okata.
