Their hopes for a reality TV show all but deflated, Richard and Mayumi Heene, the Colorado couple who allegedly staged the runaway balloon stunt as a marketing ploy, continue to stay out of the public eye.
We did see a brief glimpse of Richard Heene Tuesday morning when he answered the door at the family's home in Fort Collins, CO.
Two men had come to the Heene home, looking to retrieve some helium tanks Heene had rented to inflate the saucer-shaped balloon.
They removed the tanks and minutes later, Heene handed them a valve for the tanks.
Meanwhile, Larimer County investigators have been pouring over e-mails, phone records and financial documents from the Heene home as they decide what, if any, charges will be filed against the couple.
Authorities say once their investigation is complete, they will forward their findings to prosecutors -probably next week --to decide if the Heenes should be charged with falsely reporting that their 6-year-old son, Falcon, had drifted away in the home-built helium balloon.
Whatever the outcome, Sheriff Jim Alderden says it's unlikely the couple will spend any time behind bars.
The Federal Aviation Administration has opened its own investigation into the balloon flight, spokesman Mike Fergus said Tuesday. He said the inquiry began either Friday or Monday, but he didn't know how long it would take.
