Richard Heene, the father of Balloon Boy, began serving his jail sentence on Monday.
Heene reported to Colorado's Larimer County Detention Center around 8:30 a.m. local time, spokeswoman Eloise Campanella, told TVGuide.com.
Balloon Boy father sentenced to 90 days
Heene pleaded guilty in November to a felony count of attempting to influence a public servant by engineering the balloon debacle that transfixed the nation last fall. A judge sentenced him to 90 days in December. He will spend 30 days in jail, but will be eligible to serve the remaining 60 days through work release.
"Whether he gets into work release and so forth, all of that is totally up to him. You don't automatically go from the jail to work release," Campanella said. "He's got to do everything it takes to get into work release. He has to find a job himself. If everything else is fulfilled, he'll finish the sentence on work release."
Balloon boy bill comes due: $42,000
Heene's wife, Mayumi, who pleaded guilty to a misdemeanor count of false reporting to authorities, was sentenced to 20 days in jail, which she will serve once her husband completes his time to ensure that one parent will be with their three sons.
The Heenes are also on probation for four years, and Richard Heene must perform 400 hours of community service.
Richard and Mayumi Heene plead guilty
Last week, Richard Heene appeared on Larry King Live and denied that the balloon boy incident was a hoax, saying he truly believed his 6-year-old son, Falcon, was inside the balloon as it floated above the Colorado skies. He also told King that he pleaded guilty to prevent his wife from being deported to her native Japan.

Larimer County Sheriff Jim Alderden, however, said the evidence against the couple was "overwhelming." "There's no doubt in my mind that this thing was a hoax," he said.
