Gregory McRoberts, 24, was last seen the evening of December 12, 1991, in Lee Township, Midland County, after his car broke down. He rode a bicycle away from his home, reportedly heading to work on the disabled vehicle, and was never seen alive again. A missing person report was filed on December 16, prompting a search that ended on January 4, 1992, when his body was found partially submerged in a ditch alongside South Meridian Road.

Investigators concluded McRoberts was the victim of a hit-and-run. Evidence at the scene pointed to a light blue 1982–1987 four-door Oldsmobile Cutlass Supreme or Cutlass Supreme Brougham with damage to the right front corner. No driver was identified and the case later went cold. On March 25, 2005, his parents received an anonymous two-page typewritten letter claiming responsibility and apologizing, but the author’s identity was not disclosed.

No arrests have been announced. If anyone knew Gregory, saw a damaged light blue Cutlass Supreme in late 1991, or recognizes details in the confession letter, please come forward with information.
