The 6-year-old boy at the center of the runaway balloon saga got sick twice on national television when he and his father were asked during separate TV interviews what he meant about his comment that "we did this for a show."

Sheriff Jim Alderman says his investigators believe there was no hoax, but will seek a new interview with the family after the CNN broadcast to clarify the statement.

During an ABC interview, Falcon Heene said Friday: "Mom, I feel like I'm going to vomit." He then left the room with his mother and could be heard gagging.

During a live interview on NBC shown simultaneously on Friday, Falcon threw up into a container when his father was answering the same question.

Falcon vanished around the time that a homemade helium balloon floated away from his home, setting off a national uproar as authorities scoured the plains of northern Colorado for the youngster.
