The Tokyo High Court on Tuesday sentenced serial rapist Joji Obara to life in prison for kidnapping Briton Lucie Blackman and mutilating her corpse eight years ago, after a lower court acquitted him of the charges.

The high court also upheld the Tokyo District Court's life sentence for Obara, 56, for nine other rape cases, including that of an Australian woman who died from an overdose of sleeping drugs Obara slipped her before the assault.

Dressed in a dark suit and brown-framed glasses, Obara nervously wiped his face with a blue handkerchief before the judge read out the 1 1/2-hour decision. As the ruling was being announced, Obara stared at the floor and remained motionless.
