Jennifer Anne Douglas was 17 when she left home in Denver’s Park Hill neighborhood on the morning of July 16, 1984. A straight-A student at East High School and an avid cyclist who sometimes rode as far as 60 miles, she told her mother she planned to ride the Highline Canal trail and be home that afternoon. A witness saw her on Monaco Parkway heading north around 10:00 a.m., and she was due at a ballet class from 4:00 p.m. to 9:00 p.m., but she never arrived.

Jennifer vanished without a trace. Her black Univega 12-speed bicycle, carrying Denver Police tag number 12083, was never recovered. At the time she disappeared she was 5 feet tall, 87 pounds, with blond naturally curly hair, blue-green eyes, contact lenses, and wearing blue and green khaki shorts, black Nike sneakers and a blue fanny pack. The disappearance is classified as a non-family abduction; family and police believe she was taken against her will.

There are no reported physical clues from the Highline Canal searches and neither Jennifer nor her bike has ever been found. Does anyone remember seeing Jennifer or that distinctive Univega bike on July 16, 1984, or have information that might help resolve what happened?
