Federal and state law enforcement officials in Georgia used genealogy DNA to identify both a murder victim and her killer in a 1988 homicide that went unsolved for decades.

They say it’s the first time the novel but controversial forensic technique that connects the DNA profiles of different family members was used to learn the identities of both the victim and the perpetrator in the same case.

“It’s extremely unique,” Georgia Bureau of Investigation special agent in charge Joe Montgomery said at a recent press conference. “That, to me, is incredible because as an agent you live with these cases.”
