On the evening of August 24, 1988, Stephen A. Harris, a Caucasian male, was fatally shot on Olio Road near Geist Reservoir in Hamilton County, Indiana. Harris and a companion had been fishing and were returning to their vehicle when an assailant approached from behind and fired at short range, killing the elder Harris.

Accounts from the time say Harris was with his 16-year-old stepson when the attack occurred. After the first shot, the stepson fled and later described the shooter as a Black male with large shoulders, wearing a cap and dark clothing. Despite that description, the case went cold and no arrests were made in the decades that followed.

The Indiana State Police continue to list the death as an unsolved homicide and have periodically asked anyone with information to come forward. If anyone remembers seeing something on Olio Road near Geist Reservoir that night or knows anything about the shooting, please share what is known with investigators.
