ORLANDO, Fla. (AP) -- The Florida sheriff's office that investigated Caylee Anthony's death says it overlooked a computer search for suffocation made from the little girl's home on the day she was last seen alive.
Orange County sheriff's Capt. Angelo Nieves said Sunday that the office's computer investigator missed a June 16, 2008, Google search for fool-proof suffocation methods. The oversight was first reported by Orlando television station WKMG. It's not known who performed the search. The station reported it was done on a browser primarily used by the 2-year-old's mother, Casey Anthony.
The girl's body was found six months after she disappeared.
Casey Anthony was acquitted of her daughter's murder in 2011. Her attorneys argued that the toddler accidentally drowned in the family pool and that Casey Anthony's father helped her cover it up.
