The remains were discovered in May 2009 off of Interstate 185 just south of the Troup County line. Authorities say the remains belong to a black female, age 35 to 59.
GBI spokesman John Bankhead said investigators have checked the missing persons cases in that area but the remains do not match up with those. Initially, investigators thought the skeletal remains belonged to a missing Talbot County woman but a DNA test proved otherwise.
GBI has provided a sketch of the woman in hopes that someone can identify her.
