Authorities have said DiMaggio had an "unusual infatuation" with Hannah, although the father said he never saw any strange behavior.

An Amber Alert was issued, and tips led investigators to Oregon after DiMaggio and the teen were reportedly spotted there.

But it wasn't until the Idaho horseback rider called in his tip that investigators found a major lead - DiMaggio's car, hidden under brush at a trailhead on the border of the Frank Church River of No Return Wilderness in central Idaho.

A contingent of about 270 law enforcement officers from the FBI, the Valley and Ada County sheriffs' offices, Idaho State Police, the US Marshals Service, and the Border Patrol, aided by experts from federal land management and wildlife agencies, worked around the clock to figure out the best way to track DiMaggio and the teen in the roadless area.

San Diego County Sheriff William D. Gore announced Hannah's rescue and DiMaggio's death from a news conference in California. He said members of his office notified Hannah's father, Brett Anderson, of her rescue.

"He was very relieved and very excited and looking forward to being reunited with his daughter," Gore said.

At a separate news conference in Idaho, Dearden said she didn't know if DiMaggio fired shots at officers but there were no reports of any injuries to authorities involved in the encounter. Cascade residents gathered behind Dearden, Rook and the other officials gathered at the news conference and cheered at the news of Hannah's rescue.

Rook said FBI victim specialists were working with Hannah and her family to get them the resources they need.

"As grateful as we are that she was recovered safely, we also remember the other victims in this case who lost their lives," Rook said.

FBI policy calls for an investigation whenever an agent fires a weapon, Rook said. A team from Washington, was preparing to investigate the events at the campsite, and until that investigation is complete, Rook said she couldn't share any other details.
