For 40 years, Alan’s rescue was seen as miraculous—until DNA linked him to the cold case murders of two women, Barbara Jo Oberholtzer and Annette Kay Schnee, who vanished the same night in Breckenridge, Colorado. The two women were later found shot to death. A key clue was Annette’s orange sock, which matched one found near Barbara Jo’s body, confirming they had been killed by the same person.
