According to Pennsylvania State Police, the police officer with the city’s police department shot 54-year-old Joseph Miller of Clarendon, Pa., around 7:30 p.m. following a traffic stop on Route 6, just outside of the city limits.

Police say Miller was pulled over because he was driving erratically. When the officer approached Miller’s vehicle, Miller reportedly became agitated and started loading an AK-47 rifle he had with him in the vehicle.

When Miller failed to obey the officer’s commands and continued to load the weapon and exit the vehicle, the officer fatally shot Miller. No one else was injured in the shooting.

Pennsylvania State Police said the investigation is ongoing but at this time it appears the shooting was justified.
