Caliyah McNabb, who was born premature on Sept. 23, was found under a log about a quarter of a mile from her home, according to Newton County Sheriff's Capt. Keith Crum.
She weighed just five pounds.
The infant's mother was questioned by police and released, WGCL reported. She is not considered a person of interest.
Officials wanted immediately to speak with the father, Christopher McNabb, but were not able to locate him immediately after the infant was found.
According to local reports, Mr. McNabb was later found near a convenience store where witnesses said he told them he didn't kill his baby.
McNabb was arrested Sunday evening on the unrelated violation and brought in for questioning.
Also released Tuesday was the 911 call made by Caliyah's mother on Saturday.
