Attorneys for the families of three women slain during a visit to Yosemite National Park said Wednesday they are preparing to file a wrongful death action against the motel where the victims stayed, as well as against suspected slayer Cary Stayner.

San Francisco attorney Steven Fabbro said the litigation would name the Cedar Lodge, where the women had rented rooms, and motel handyman Stayner, who has confessed to killing them. The suit would ask for an unspecified but “significant amount,” he said.
