The severed head of a young woman found Friday on Mount Garyu in Hiroshima Prefecture has been confirmed to be that of a 19-year-old student missing in Shimane Prefecture, police said early Saturday. Miyako Hiraoka, a freshman at the University of Shimane in Hamada, about 25 km from the mountain, had been missing since the evening of Oct. 26, when she failed to return to her dormitory after finishing her part-time job.
