Julie Cunningham was last seen on March 15, 1975 in Vail, Colorado. The sporting goods employee and part-time ski instructor spoke briefly to her mother by phone that day, then left her Apollo Park apartment early in the evening to join her roommate at a local tavern. She was never seen again and was reported missing on March 21.

Serial killer Ted Bundy confessed to her abduction and murder three days before his execution in Florida in 1989. He said he drove her 80 miles west of Vail to an isolated spot several miles north of the town of Rifle in Garfield County. She was then murdered and buried in a shallow grave. Despite a detailed description of the burial site provided by Bundy and an intensive search of the area, her remains were never recovered. (Information retrieved from NamUs.gov)
