Bobby Panknin, a 4-year-old Spokane boy, disappeared without a trace on Aug. 3, 1963, while on a family camping trip to Deep Lake Resort near Northport, Wash. His mother carried this photo with her until she died in December 1998. Despite a massive search, no one knows whether the 2-foot-8, 30-pound boy was abducted or - more likely - taken by a bear or a cougar. Min Pins, Unexplained Mysteries, Lake Resort
