Here's a short story:

(CNN) -- In the middle of the Idaho wilderness, a man on horseback had a brief conversation with two campers. The rider's realization later that he may have been talking to California Amber Alert suspect James DiMaggio and his alleged teenage captive has now focused a nationwide manhunt for the pair on the rugged mountain area in central Idaho. 

The horseback rider saw the man and girl Wednesday and struck up a brief conversation with them, Andrea Dearden, spokeswoman for the Ada County Sheriff's Office, said Friday. 

He was not aware of the manhunt at the time, but he called the Amber Alert tip line after he saw a news account that night and realized the pair matched the description of DiMaggio and 16-year-old Hannah Anderson, she said. 

The rider's impression of the pair was "it seemed odd but nothing as alarming," Dearden said. 

"They did speak and exchange pleasantries. I don't think there was a lot of information exchanged," she said. "He left the conversation believing they were camping in the area." 

The rider said the man and girl were on foot, hiking with camping gear, Dearden said. 

Dearden appeared to be correcting authorities' earlier reports that the suspect and girl were spotted by more than one horseback rider. 

Investigators set up checkpoints where DiMaggio and Hannah were believed to be traveling in the River of No Return Wilderness area, about 15 miles outside Cascade, Dearden said. 

Authorities haven't yet evacuated any homes or businesses, she said, adding, "We have those access points secured."  (End of story)
