Floyd Heidelberg, 56, was shot and killed inside his apartment at 2127 Gilbert Avenue, Apartment 61, in Cincinnati, Ohio, on July 28, 1986. Authorities have described the incident as appearing to be drug-related, and investigators believe narcotics played a role in the motive.

The Cincinnati Police Department led the investigation, with assistance from the Ohio Attorney General’s Office and the Bureau of Criminal Investigation on the case’s inclusion in unsolved homicides listings and cold-case efforts. Despite efforts to gather evidence and solicit public tips, the homicide remains unsolved.

Anyone who lived in the neighborhood at that time or who has information about drug activity or people connected to that address in July 1986 is asked to come forward with tips that might help bring resolution to the family.
