Larimer County Sheriff Jim Alderden said no charges had been filed yet, and the parents weren't under arrest. He said he expected to recommend charges of conspiracy, contributing to the delinquency of a minor, making a false report to authorities and attempting to influence a public servant.
Some of the most serious charges each carry a maximum sentence of six years in prison and a $500,000 fine. The sheriff said if charges were filed, his office would seek restitution, but he didn't know the total cost of the rescue effort, which included military helicopters, a ground rescue and even a mounted posse. Officials also rerouted planes around the balloon's flight path and briefly shut down some flights from Denver International Airport.
Alderden said the parents Richard and Mayumi Heene "put on a very good show for us, and we bought it."
Alderden said at an extraordinarily candid news conference that the boy, Falcon Heene, may not have even been hiding in the rafters of the family's garage during the intense five-hour search for him Thursday afternoon.
"For all we know he may have been two blocks down the road playing on the swing in the city park," the sheriff said.
Richard and Mayumi Heene were shopping at a Wal-Mart with their three sons as Alderden told reporters at the sheriff's station that the whole thing was a hoax.
Richard Heene said he's "seeking counsel," though it was unclear whether he was talking about hiring an attorney.
"This thing has become so convoluted," Heene told The Associated Press as tears welled up in his eyes.
He said his wife was holding together better than he was.
The sheriff said all three of the Heenes' sons knew of the Thursday hoax, but likely won't face charges because of their ages. The oldest son is 10. One of the boys told investigators he saw his brother get in the balloon's box before it launched.
Heene, a storm chaser and inventor, and his family have appeared on the ABC television reality show "Wife Swap." Alderden said the couple met in acting school in Hollywood. Richard Heene has described himself as an amateur scientist, but Alderden said Heene has only a high school education.
"He may be nutty, but he's not a professor," Alderden said, adding Heene showed "no evidence of remorse" for the episode.
Alderden said interviews with the parents Saturday resulted in enough information to get a warrant to search the house.
