Colleen Emily Orsborn was a 15-year-old from Daytona Beach who disappeared on March 15, 1984, after skipping school to go to the beach. Her family reported her missing four days later. Three weeks after she vanished a decomposed body was found in a shallow grave near a lake in Orange County, Florida, but the remains were not identified as Colleen at the time because of differences in physical characteristics and the absence of a previously documented healed fracture.

In March 2011 DNA testing confirmed the body was Colleen’s. Investigators have long linked her death to Christopher Wilder, an Australian-American serial killer known as the Beauty Queen Killer, who was reportedly staying at a motel near Interstate 95 in Daytona Beach on the day Colleen disappeared. Witness accounts and circumstantial evidence suggest Wilder may have approached her by offering money for modeling photographs, a tactic he used with other victims. Wilder died by suicide during a shootout with police in April 1984.

No other suspects have been publicly identified and the case remains officially unsolved. If anyone knew Colleen, saw her on March 15, 1984, or has information about her disappearance, please come forward.
