school girl

Junko Furuta (古田 順子 Furuta Junko) was a Japanese high school student who was abducted, tortured, raped, and murdered in the late 1980s. Her murder case was named "Concrete-encased high school girl murder case" (女子高生コンクリート詰め殺人事件, Joshikōsei konkurīto-zume satsujin-jiken), due to her body being discovered in a concrete drum. The murder was mainly perpetrated by four teenage boys, Hiroshi Miyano (now Hiroshi Yokoyama), Jō Ogura (now Jō Kamisaku), Shinji Minato and Yasushi Watanabe.
Approximately 100 people knew about Junko Furuta's captivity, but either did nothing about it or themselves participated in the torture and murder. Most of the participants were friends of the teenage boys, who were low-ranking members of the Yakuza.
