Mychiska Patterson

Deadly force

Twenty-eight-year-old Dean Ricketts was acting out scenarios he learned in training. A single gunshot killed Patterson, a jailer who had worked for the Fulton County sheriff's department for two years. Atlanta police say Ricketts had removed the magazine from the .40-caliber Glock pistol he was using in the role-playing game, but a bullet remained in the chamber. Ricketts--as a detention officer--was not authorized to carry a firearm, and the gun was not sheriff's department property, police said.
