Capt. Loyd Baker, commander of the Tuscaloosa County Homicide Unit, says the death of the unidentified girl appears to be heat-related.
Baker says the girl's siblings may have been playing in the car with her while parents got groceries Friday, but parents later noticed she was not with them.
Baker says the father searched the house near the Echola community and eventually found the girl on the floor of the car by the front passenger seat.
He said the doors were not locked, but were closed along with the windows.
