CASCADE, Idaho — A man suspected of killing a California woman and her young son before fleeing with her 16-year-old daughter was killed in the Idaho wilderness and the teen was found safe Saturday, authorities said.

James Lee DiMaggio, 40, was killed by FBI tactical agents at the north end of Morehead Lake, San Diego Sheriff William D. Gore said. The shooting came after officers participating in a massive manhunt spotted a campsite from the air.

Gore declined to discuss details of DiMaggio’s death, saying authorities in Idaho would release details at a news conference planned for Saturday night.

He said San Diego sheriff’s authorities had notified Hannah Anderson’s father that she was rescued. “He was very relieved and very excited and looking forward to being reunited with his daughter,” Gore said.

Federal and local law enforcement spent Saturday combing through Idaho’s rugged Frank Church River of No Return Wilderness in search of Hannah and DiMaggio. The wilderness is the largest roadless area in the lower 48 states, sprawling across central Idaho and reaching north to the Montana border.

DiMaggio is suspected of killing Hannah’s mother, 44-year-old Christina Anderson, and her 8-year-old brother Ethan Anderson, whose bodies were found Aug. 4 in DiMaggio’s burning house in California near the Mexico border.

DiMaggio’s car was found Friday morning about 40 miles east of the tiny town of Cascade, parked where the dirt road ends and the Sand Creek trailhead enters the wilderness area.

Detectives with the San Diego County Sheriff’s Department finished searching DiMaggio’s car Saturday afternoon. They had the vehicle towed to a garage in Cascade for further processing.

The discovery of the car came about two days after a horseback rider reported seeing the man and girl hiking in the area. Ada County Sheriff’s department spokeswoman Andrea Dearden, who is helping the Valley County sheriff’s department handle the case, said the rider didn’t realize the pair were being sought until he got home and recognized them in news reports.
