Joji Obara, accused of fatally drugging two women, including British hostess Lucie Blackman, and raping eight others, made his final plea Monday at the Tokyo District Court, denying all charges against him.

"It would be impossible for me to do such a thing," Obara, 54, said, referring to the mutilation and burial of Blackman's body in a cave. "The prosecutor's statements contain no truth."

Obara's lawyers also claimed prosecutors have tried to hold him responsible for Blackman's death despite having no evidence.
