RELATED SLIDESHOW: Pictures of the balloon floating over Colorado
The boy was found hiding in the home's garage Thursday afternoon, hours after the balloon launched and traveled more than 50 miles.
Sheriff Jim Alderden said Friday the suggestion that the boy, Falcon Heene, was coached to hide seems inconceivable. He says the boy thought he was responsible for the balloon coming untied and hid because he was afraid he'd be in trouble.
Questions were raised about the incident after the boy said "we did this for a show" in a live interview with CNN. The boys' parents are storm chasers who appeared in the ABC reality show "Wife Swap."
