OSAKA -- The parents of three 7-year-old girls fatally stabbed in a killing spree in June 2001 at an elementary school in Ikeda, Osaka Prefecture, called Thursday for the defendant to be sentenced to death.

The father of Kana Tsukamoto told the Osaka District Court that they want Mamoru Takuma to "pay for the crime with his life" and described his very existence as a "social ill."

He also blasted Takuma's lawyers for seeking another psychological examination.
