Charles Harbaugh was 22 when his body was found in Livingston County, Michigan, on March 12, 1973. Reports state he was fatally shot, prompting a homicide investigation as authorities reconstructed his final hours in the community.

Investigators identified a suspect and arrested Wilburn D. Stewart. Prosecutors tried Stewart for the killing; a jury found him guilty of first-degree murder and he was sentenced to life in prison without the possibility of parole. Stewart’s later appeal was unsuccessful when the Michigan Court of Appeals upheld the conviction in 1975.

Anyone who knew Charles, his movements in Livingston County in early 1973, or has information about the case is asked to come forward.
