For decades, Valerie Nagle tirelessly sought answers about her older sister, Marion Vinetta Nagle McWhorter, who was last seen in Oregon in 1974. Her persistent search, which involved poring over online databases of unidentified persons and submitting her DNA to a popular ancestry website, finally yielded a breakthrough this summer.
In June, Oregon authorities contacted Ms Nagle "out of the blue" to request a DNA comparison for a cold case known as "Swamp Mountain Jane Doe." Her genetic material ultimately confirmed that remains found near a mountain creek in Oregon’s Central Cascades in 1976 belonged to her sister.
