Remember this morning when we said that missing 3-year-old Caylee Anthony's mom, Casey, had a car that her mother described as smelling like a "dead body"? Well uh, that's because there was a dead body in the trunk of Casey's Pontiac. The Orlando Sentinel is reporting this afternoon that "air sample tests from Casey Anthony's car show a decomposing human body was inside the trunk, a sheriff's office official just confirmed." In addition, "Officials have offered Anthony a partial immunity deal if she admits 3-year-old Caylee Marie died as a result of an accident." [Orlando Sentinel]
