"Like a square peg going into a round hole."
That's how Mark John, an Idaho man who spotted and helped lead authorities to James DiMaggio and 16-year-old Hannah Anderson, described the pair.
DiMaggio is now dead, shot and killed by an FBI agent in the Idaho wilderness.
He was suspected in the slayings of Hannah's mother and brother in California and in the girl's kidnapping.
"They were just like a square peg going into a round hole. They didn't fit. He might have been an outdoorsman in California, but he was not an outdoorsman in Idaho," John told reporters Sunday.
"He just didn't fit."
John, his wife, Christa, and another couple, Mike and Mary Young, were out on horseback when they happened upon DiMaggio and Hannah on Wednesday twice, once on a trail and once at a lake.
Red flags went up immediately.
All their gear looked brand new, said John. They had no rain equipment.
Another flag, said Mike Young, was that DiMaggio said he was headed for the Salmon River, but was going in the wrong direction.
Hannah hid her face and looked kind of scared, he said. Young and the others thought that maybe their horses had frightened her.
She and DiMaggio were hiking. He had a backpack. She was wearing what looked like either sweatpants or pajamas, Young said. He noticed they had a two-man tent set up in a ridge.
Another red flag.
The camping spot had no water, and a tent on a ridge would act like a "lightning rod," Young said.
"Usually when you meet people in the back country, you have a pretty good encounter, you know, and talk about where they've been and where they're going. But they didn't want to talk," he told reporters.
After their group passed DiMaggio and Hannah, he turned to the others and said he thought something wasn't right.
"Just kind of a gut feeling, you know, like they didn't belong," said Young.
'One chance in a trillion'
Their group ran into DiMaggio and Hannah later at a lake. The girl was soaking her feet in the water, and DiMaggio was off to the side petting a gray cat, said John.
Just as he and the others were getting ready to go, Hannah said something that made little sense at the time.
"She said, 'Looks like we're all in trouble now,' or 'We're in real trouble now,'" said John. "I thought it extremely strange."
No one in his group was aware of the massive manhunt under way.
Hannah had been missing since August 3. The bodies of her mother, Christina Anderson, and 8-year-old brother, Ethan, were found one day later in DiMaggio's burned house in San Diego County, California.
But eventually, John, a former county sheriff and retired Army officer, called police.
After he and his wife got home Thursday, he turned on the television and saw an Amber Alert for Hannah. She looked like the girl they'd just seen.
