In an affidavit made public today, the sheriff's office in Larimer County, Colo., says that Mayumi Heene admitted last Saturday that the whole "balloon boy" story was a hoax.

Mayumi, mother of six-year-old Falcon, told investigators that it was all done to make the family more attractive to the media, the affidavit — used to secure a search warrant for the Heene family's home — states.

KUSA-TV of Denver has posted the document here.

Bear in mind that the father in this family, Richard Heene, has maintained that the adventure was not a hoax. The Coloradoan writes today that:

Richard Heene's attorney David Lane and Mayumi Heene's attorney Lee Christian both have not seen the affidavit, which was made available to the public today through the Larimer County courthouse.

"The fact that they're releasing an affidavit before an arrest is made — I've never seen that before," Lane said in a phone interview. "It's further proof of what that sheriff will do to further his own agenda and try to make it unfair to the Heenes."

In case you've been in a news media blackout for the past week or so, on Oct. 15 a homemade weather balloon took off from the Heenes' backyard and it was initially thought that Falcon was inside its plywood basket. The whole drama was broadcast live on TV across the nation. Later, the family claimed he had been hiding in an attic because he thought he was in trouble. But now, the local sheriff plans to press criminal charges.
