Rescued 16-year-old awaits reunion with father

Updated 5:11 p.m. ET

CASCADE, Idaho A California teen missing for more than a week after she was abducted by a man suspected of killing her mother and brother has been rescued, her captor killed, and a reunion with her father was expected Sunday at an Idaho hospital.

But for law enforcement investigating the ordeal, there is still plenty of work to be done.

Two camping couples tipped authorities when they connected that a suspicious man and a young girl they saw on the trail matched an amber alert they later saw on television.

"When the showed up to the lake, he was like a square peg in a round hole - he didn't fit," said one of the camping men, rancher and former county sheriff Mark John.

FBI agents are processing evidence at the campsite in central Idaho's Frank Church River of No Return Wilderness where they first discovered 16-year-old Hannah Anderson and the man suspected of abducting her, 40-year-old James Lee DiMaggio. Details about the operation that ended in Hannah's rescue are being released slowly.

Law enforcement agents first spotted two people who looked like Anderson and DiMaggio on Saturday afternoon, as they flew over the wilderness area in a plane, according to a statement from Ada County Sheriff's spokeswoman Andrea Dearden.

The air was filled with smoke blown in from distant wildfires, and that made both flying and seeing the ground tough, Dearden said. The law enforcement commanders decided to send in an FBI Hostage Rescue Team immediately to get Hannah while they could.

The mountainous area is extremely steep, and the closest point where the helicopters could drop the team was more than a two-hour hike away. The agents crept close to the camp, waited until DiMaggio and Hannah separated, and then moved in.

The FBI moved the teen to an area where she could be picked up by a helicopter. The FBI won't release details about what happened between DiMaggio and law enforcement at the campsite until an investigation is complete, other than to say DiMaggio was shot and killed.

FBI Special Agent in Charge Mary Rook from Salt Lake City said the FBI will continue to work with law enforcement in both Idaho and California as the case transitions back to the San Diego Sheriff's Department.

Anderson appeared to be uninjured and was taken to an Idaho hospital where crisis counselors and health care providers were assisting her. Her father was expected to arrive in Idaho on Sunday to reunite with her.

"We will make sure she gets as much care as possible, physically and emotionally," said Dearden.

The FBI said it was sending a team to investigate what unfolded before, during and after the shooting.

The location wasn't far from what had been the last known sighting of the pair. A horseback rider called authorities Thursday night to report that he had seen two people who resembled Anderson and DiMaggio with camping gear on a trail near the lake. The rider, whose name wasn't released, didn't realize they were subjects of a massive search until he got home and saw news reports. He was expected to speak to media Sunday.

The case began when the charred bodies of Hannah Anderson's mother, Christina Anderson, 44, and the teen's 8-year-old brother, Ethan Anderson, were found in DiMaggio's burning house outside San Diego, near the Mexico border.

DiMaggio was close to the family. Christina Anderson's husband, Brett Anderson, has described him as a best friend and said the children thought of him as an uncle.

As CBS News correspondent Carter Evans reported, Hannah's father had pleaded all week to the man he once considered a good family friend. "The damage is done," Anderson had said earlier before the rescue. "I'm begging you to let my daughter go. You've taken everything else."

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.

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.

The father described a range of emotion in a text message to CNN.

"I am nervous excited saddened 4 my wife and son and worried what my daughter has been through," he wrote to the network. "It's now healing time. Keep us in your prayers."
