HAYMARKET, Va. (AP) — Prince William County police say DNA from skeletal remains found in the Haymarket area have been linked to a teen who went missing in 1980.

Authorities said Wednesday that DNA samples collected from the family of Cynthia Joan Gastelle in 2011 matched the remains found by a hiker in 1982 in what was then a remote section of Prince William County. The match was produced by a type of test that has only been used in Virginia since 2008.

Police say Gastelle left her Takoma Park, Md., home on April 3, 1980, to attend job interviews. The 18-year-old made it to one appointment at a delicatessen and then disappeared.

Police and the teen’s family are now appealing to the public for leads in the long-standing mystery.
