On December 30, 1981, 23-year-old Harriet Kaltenbach, known as Sissy, was found shot and deceased while seated in a vehicle parked in front of an apartment complex office on Plyley’s Lane in Chillicothe, Ohio. She was pronounced dead at the scene when law enforcement arrived.

The killing remains unsolved. The Chillicothe Police Department and the Ohio Bureau of Criminal Investigation have both been involved and are asking anyone with information about the events leading up to Harriet’s death to come forward. No suspects have been identified in this case.

Does anyone have information about Harriet’s last known movements or who she might have been with that night?
