Sheriff turns to family tree databases to find ID of first victim of serial killer

MARION, Ohio — The Marion County Sheriff is turning to DNA databases used by amateur genealogists to fill in their family trees in his latest effort to find the identity of a woman who may be the first victim of serial killer Shawn Grate. Those databases were used to solve recent high profile cases including the arrest of the Golden State Killer after he murdered dozens and eluded police for decades.
