MT. ORAB, Ohio— Authorities say a Mount Orab man who had been booked and released on drunk driving charges returned to the police station and shot an officer in the back, then was fatally shot himself.

Mount Orab Police Chief Bryan Mount says 61-year-old George Ruby of Mount Orab was killed about 4 a.m. Sunday. Patrolman Justin Conley was shot but was not seriously injured.

A few hours earlier, Conley had arrested Ruby on drunk driving charges. Ruby had been taken to the station 30 miles east of Cincinnati and released to his wife.

Police say Ruby returned later and opened fire when Conley walked out. Conley used his radio to call an officer inside the station, and the two exchanged fire with Ruby.

Ruby was pronounced dead at Mercy Mount Orab Hospital.

The state is investigating.
