ORLANDO, Fla. -- FBI tapes released Friday reveal new information about Casey Anthony and her web of lies surrounding the disappearance of her daughter Caylee. Casey Anthony told lie after lie to her parents and even stole from her daughter's own piggy bank.

Because of Casey's arrest, her parents discovered dozens of compromising photographs of her that were on the Internet, a whole life they said they knew nothing about.

Detectives told George that they were going to find out what happened to Caylee, regardless of whether Casey or the Anthonys got hurt in the process. During the interview on July 31, they made it very clear their focus was finding Caylee.
