Murder of Rie Isogai

Rie Isogai (磯谷 利恵, Isogai Rie; 20 July 1976 – 24 August 2007) was a 31-year-old Japanese woman, an office clerk who was robbed and murdered in Aichi Prefecture on the night of 24 August 2007 by three men who became acquainted through an underground message board. Because the three men met on an underground website, the case is frequently called the Dark Site Murder (闇サイト殺人, Yami Saito Satsujin) in Japan, "dark site" being the Japanese term for underground websites. Despite Japan's death penalty not normally being used in cases involving a single murder, Isogai's mother launched a petition to have the three killers face the death penalty; one was sentenced to death on 18 March 2009, while the other two, including serial killer Yoshitomo Hori, were sentenced to life in prison on 13 April 2011.
