This combination of undated photos provided by the San Diego Sheriff's Department shows James Lee DiMaggio, 40, left, and Hannah Anderson, 16.

California authorities have been searching for 16-year-old Hannah Anderson since her mother and what's thought to be her 8-year-old brother were found dead in a burned-down house on Monday. Now they are focusing their search on the central Idaho wilderness, where a horseback rider says he exchanged pleasantries with a teenage girl and James DiMaggio, the man suspected of killing her family and kidnapping her. The pair were on foot, hiking with camping gear, which was "odd, but nothing as alarming," according to the rider. There is an Amber Alert out for Anderson and they are believed to be traveling in the River of No Return Wilderness area, 15 miles from Cascade.
