Donald Clark Arnold

Sergeant Arnold was shot and killed when he interrupted a robbery at a local service station. He routinely stopped at the station during his shift to check on the graveyard shift employees.

When he arrived at the service station the three suspects took the attendant and hid in the bathroom. As Sergeant Arnold walked through the building one of the suspects fired through the open door, striking Sergeant Arnold several times. He was found with his service revolver still in its holster. The suspects then murdered the attendant and fled the scene.

The shooter was arrested and sentenced to death for Sergeant Arnold's murder and life for the attendant's murder. His death sentence was commuted to life in 1972.

Sergeant Arnold had served with the agency for 17 years.

I lived in Sherman when Officer Arnold was murdered. What a tragic event. I was a teenager at the time, but I remember all the coverage of the event very vividly, and I think of it every year at this time, just two days before Christmas.
