DENVER -- Richard Heene has denied that the panic started when his son was thought to have been trapped inside a runaway balloon was a hoax.
But according to court documents, his wife has told Colorado sheriff's deputies the opposite.
An affidavit used to get a search warrant for the family's home says Mayumi Heene admitted that she and her husband "knew all along" that 6-year-old Falcon was hiding in their home.
She allegedly told investigators that they had devised the hoax about two weeks earlier and "instructed their three children to lie to authorities" and the media about it.
Mayumi Heene's lawyer has not commented on the document, but Richard's has.
David Lane says he's waiting to see evidence and until then, "allegations are cheap."
The Larimer County Sheriff has said he will recommend charges against the Heenes.
The most serious charges are felonies and carry a maximum sentence of six years in prison.
