Atif Rafay and Sebastian Burns, two brilliant best friends who once wrote a screenplay about two boys wrongfully accused of murder, are now caught up in a real-life murder mystery. They are accused of murdering Rafay's family, from the upper middle-class community of Bellevue, Wash., near Seattle. The brutal murders took place in July 1994. Correspondent Peter Van Sant reports on this 10-year mystery that led investigators to Vancouver, British Columbia, Canada and involved secret videotaped operations by the Royal Canadian Mounted Police (RCMP).
