A woman vanished in Oregon in 1974. Now, remains found 2 years later have been identified as her, through DNA.

Portland, Oregon — Valerie Nagle spent decades wondering what happened to her older sister, who was last seen in Oregon in 1974. She searched online databases of unidentified persons cases looking for her and sent DNA to a popular ancestry website in the hopes of finding a match.

That all changed in June when authorities in Oregon called Nagle "out of the blue" to ask about comparing her DNA to a cold case known as "Swamp Mountain Jane Doe," she said. Nagle's DNA ultimately helped confirm that the remains of a woman found near a mountain creek in Oregon's Central Cascades in 1976 were that of her sister, Marion Vinetta Nagle McWhorter.
