Mark Dillard was killed in Dayton, Ohio, on January 14, 1979. The Montgomery County homicide remains unsolved; the Dayton Police Department has no apparent viable leads and the case is listed by the Ohio Bureau of Criminal Investigation among unsolved homicides that the state is highlighting to attract public attention.

Authorities note that investigators face challenges common to cold cases from that era, including limited forensic technology available at the time and potential witness reluctance. The BCI and local law enforcement continue to seek community assistance and urge anyone with information to contact the Bureau or Dayton Police.

Does anyone have information about Mark Dillard, his last known whereabouts, or acquaintances who might help revive leads?
