Takayuki Fukuda

Takayuki Ōtsuki (大月 孝行) was the perpetrator of the Hikari City Mother and Child Murder Incident (光市母子殺害事件) in Hikari, Yamaguchi, Japan, on 14 April 1999. On that day, when he was 18 years and 1 month old, he killed a woman (then 23 years old) and then performed necrophilia on the body, and also killed her daughter Yūka Motomura (本村 夕夏), and stole the mother's purse. He was charged with rape, murder and robbery, and was handed the death sentence although he was not of the age of maturity (20 years of age in Japan) at that time (18 years and 1 month). The appeal was rejected.

Trial
During the trial, the brutality of the details of the incident and the demands by the defense lawyers that teenagers ought not receive the death sentence were widely reported in mass media, sparking a debate within Japan. The husband, Hiroshi Motomura, of the two killed vowed to wait until his release to kill him. In 2006, the courts reviewed his case and in 2008 they sentenced him to death by hanging.
