Prosecutors on Monday demanded the death penalty for the former parents' association chief accused of murdering a 9-year-old Vietnamese girl in Chiba Prefecture last year.

Yasumasa Shibuya, 47, committed a "cold-blooded, heinous and cruel" crime in abducting, sexually assaulting and strangling Le Thi Nhat Linh, prosecutors said at the hearing at the Chiba District Court.

Shibuya, a neighbor of the girl, has pleaded not guilty to the charges.
