Diana Lynn Miller was 23 when she disappeared from Emporium, Pennsylvania, in late spring 1986. Around June 20 she left her four-year-old daughter with a relative and reportedly planned to attend the Sinnemahoning Snake Hunt, about twenty miles from home. She was last seen wearing a white t-shirt and blue jeans and has not been heard from since.

She used several names at different times, including Diane Lynn Miller, Diana Lynn Morton, and Diana Lynn Zuback. Descriptions list her as about 5 feet 4 inches to 5 feet 6 inches tall, roughly 125 pounds, with long straight blonde hair, blue eyes, and tattoos: FTW across the fingers of one hand and possibly the same on her right forearm. Reports from the time say she liked social gatherings and had an interest in the biker community; she may have gone to a party near the snake hunt at a campsite frequented by motorcycle gang members.

Very few concrete leads emerged, and the case remained open with no definitive conclusions. If anyone knew Diana, saw her around Emporium or at the Sinnemahoning Snake Hunt in June 1986, or has information about people she associated with then, please come forward.
