[4][5] Miyazaki was dubbed the "Otaku Murderer" due to his extensive collection of anime, manga, horror videotapes and hentai as well as various other forms of pornography.
He was born premature and had the rare birth defect radioulnar synostosis that caused his hand joints to be fused together, preventing him from being able to bend his wrists upwards.
[7] Miyazaki's family operated a regional newspaper company and were well known in Itsukaichi, where his grandfather and great-grandfather had served on the town council.
Miyazaki had led Konno into his black Nissan Langley, then drove westward of Tokyo and parked the car under a bridge in a wooded area.
Miyazaki burned Konno's remaining bones in his furnace, ground them into powder, and sent them to her family in a box along with several of her teeth, photos of her clothes, and a postcard which read, 「真理さん、骨、火葬、調査して、証明して」 ("Mari.
He killed Namba, tied her hands and feet behind her back, covered her with a bedsheet, and placed her body in his car's trunk.
On 20 December, Namba's family received a postcard sent by Miyazaki with a message assembled using words cut out of magazines: 「絵梨香、かぜ、せき、のど、楽、死 」 ("Erika.
Miyazaki took the corpse into his apartment and spent the next two days engaging in sexual acts with her body, taking photos and videos of the remains in various positions.
Fearing that the police would find Nomoto's body parts, Miyazaki returned to the cemetery and the hills two weeks later and carried the remains back to his apartment, where he hid them in his closet.
He was taking photographs of the younger daughter, whom he had convinced to strip nude, when he was caught by their father, who attacked Miyazaki but was unable to restrain him.
[13][11] After fleeing on foot, Miyazaki eventually returned to the park to retrieve his car, whereupon he was arrested by police responding to a call by the father.
[15][better source needed] His killings caused a moral panic against otaku, with speculation that anime and horror films had made him a murderer.
[16][better source needed] Keigo Okonogi, a psychoanalyst at Tokyo International University, told the Shūkan Post that: The danger of a whole generation of youth who do not even experience the most primary two- or three-way relationship between themselves and their mother and father, and who cannot make the transition from a fantasy world of videos and manga to reality, is now extreme.
[17] Another critic, Fumiya Ichihashi, suspected the released information played up to public stereotypes and fears about otaku, as the police knew they would help cement a conviction.
[18] Sharon Kinsella asserts that large collections of manga and videos were typical in the rooms of youths living in the Tokyo area at the time.
"[25] Minister of Justice Kunio Hatoyama signed Miyazaki's death warrant on June 17, 2008, and he was hanged at the Tokyo Detention House that same day.
