The Anthony family's spokesman isn't the uncle of the bondsman. The spokesman is Larry Garrison, who has been variously involved in PR and such for suspects and victims, such as John Mark Karr and Dave Holloway. The bondsman's uncle is Leonard Padilla, who is a bounty hunter with a TV show on National Geographic Channel.
So, these three guys' roles are:
1. Tony Padilla -- being responsible for paying $500,000 if Casey doesn't show up in court.
2. Leonard Padilla -- making sure that Casey appears in court and does not violate the terms of her bond. He also plans to get information from her on the whereabouts of Caylee.
3. Larry Garrison -- speaking to the press for George and Cindy Anthony (and Lee and Casey?)
