Heene, who recently was sentenced to 90 days in jail, told Larry King that the incident was not a hoax and that he pleaded guilty to charges of influencing a public servant to prevent wife Mayumi from being deported to Japan.
He further tried to explain that his son had been asked by a Japanese cameraman to show him how he got into the attic — apparently for the cameraman's own TV program. "That's why Falcon answered [as he did]," Heene said.
Larimer County Sheriff Jim Alderden, however, doesn't buy it and said the evidence is "overwhelming."
"I'm shocked he would make such statements," Alderden told King. "There's no doubt in my mind that this thing was a hoax."
The interview will air Friday on Larry King Live at 9/8c on CNN.
