ORLANDO, Fla. (AP) — Prosecutors proved Casey Anthony was a liar, but convinced the jury of little else. The government failed to establish how 2-year-old Caylee Anthony died and they couldn't find her mother's DNA on the duct tape they said was used to suffocate her. There was conflicting testimony on whether the putrid smell inside the family's car was a decomposing body or simply trash, and it was never quite clear why chloroform was so important.
