ORLANDO, Fla. (AP) -- Florida police investigating the disappearance of three-year-old Caylee Anthony say lab tests confirm there had been a decomposing body in the trunk of her mother's car.
The Orange County, Florida, sheriff's office says investigators now think there's a strong probability that Caylee is dead. The sheriff's department says other evidence not made public also leans in that direction.
Caylee's mother, Casey Anthony, remains jailed on unrelated charges and has been considered a "person of interest" in the case. She's been offered limited immunity in exchange for her cooperation. The offer expires tomorrow.
Caylee was reported missing in mid-July, about a month after she was last seen. Casey Anthony told investigators she dropped the girl off with a baby sitter and went to work. Sheriff's detectives say that's a lie.
