Michael B. Hunter was 23 when he was last seen in Fort Collins, Colorado, on May 27, 1979. He was described as a Caucasian man with brown hair and brown eyes who wore glasses, standing between 5 feet 6 inches and 5 feet 10 inches and weighing between 165 and 180 pounds. The disappearance report was filed with the Fort Collins Police Department on June 23, 1979, under case number 79-12933.

Very few concrete details about his last day are available. Nothing public is recorded about what he was doing, what he was wearing, or any personal items he may have had, and the narrative of his disappearance remains largely blank. The case was entered into the National Missing and Unidentified Persons System on October 15, 2010, but the section describing circumstances contains no additional information.

Anyone who knew Michael, saw him in late May 1979 in the Fort Collins area, or has information that could help fill in his last movements is asked to come forward.
