#### Moonlight Sonata Murder Case (Manga: [62-67](/wiki/Volume_7 "Volume 7"), Anime: (/wiki/Moonlight_Sonata_Murder_Case "Moonlight Sonata Murder Case")/[1000-1001](/wiki/The_Moonlight_Sonata_Murder "The Moonlight Sonata Murder"))[[edit](/wiki/index.php?title=Seiji_Asoh&action=edit&section=5 "Edit section: Moonlight Sonata Murder Case (Manga: 62-67, Anime: 11/1000-1001)")]
The culprit's death.
He murdered four people because they used his father's international concerts as a front for their international drug trade and, when he stated who wouldn't cooperate any longer, they got scared that their secret might be exposed, so they locked the family in their home and set it on fire. As the famous [Sleeping Kogoro](/wiki/Kogoro_Mouri "Kogoro Mouri") explains all of this, he escapes and, while the police is looking for him, the community center building suddenly go up in flames. Having realized that he has been found out, he locks himself inside and set it on fire, intending to die like his father. Conan manages to slip in and tells him, who is sitting at the piano, to keep on living. He refuses, however, because he is already too bloodstained. Then, he grabs Conan and threw him through the window, saving his life. Afterwards, he plays one last music code message in the burning flames: "Thank you, little detective". [Ran](/wiki/Ran_Mouri "Ran Mouri") wonders why did he summon her father when he knew how risky that would be for his plan, and for Conan it wasn't just a challenge: that deep down, he wanted Kogoro to stop him.
