The Oakland County Sheriff's Department said deputies found the vehicle with apparently fresh front-end damage early Saturday in Pontiac. Investigators said the child's 49-year-old aunt later arrived at the scene and said she had been with the child's 44-year-old mother, who had run out of gas.
The Sheriff's Department said the aunt told investigators the mother left in search of drugs while she had left with the intention of finding gas for the vehicle.
The child was OK and released to the custody of his father. Police are seeking the mother.
Child neglect charges are possible against the aunt and the mother.
