Eighteen-year-old Jon Truscott Haynes arrived in Boulder, Colorado, in the summer of 1981 to attend the University of Colorado but was last seen that July at a 7-11 near 28th Street and Baseline Road. After that brief stop both Jon and the beige 1981 two-door Subaru he was driving, California plate 1CPK105, vanished. He was described as a Caucasian male, five feet ten inches, about 140 pounds, with blond hair, light green eyes and minor acne; there is no reliable report of what he was wearing that day.

The Boulder County Sheriff’s Office kept the investigation open for decades; the case was shared with other agencies and age-progressed images were later released, yet no significant breakthroughs have been reported and his disappearance remains unsolved. The absence of the vehicle raised the possibility he traveled a significant distance after the last sighting, but little else is known about his movements that day.

If anyone saw Jon, the Subaru, or remembers activity near 28th and Baseline in July 1981, can you share what you recall?
