More details are emerging in the killing of Missouri Highway Patrol Sergeant Carl Graham ten days ago now that a murder charge has been filed. The Highway Patrol says Graham was shot with a rifle, then at least once with a shotgun. Court documents say Lance Shockley borrowed his grandmother’s car and asked for directions to Graham’s home. Police say some witnesses saw the car on a road near Graham’s home later. Police say a 22-caliber shel found in Shockley’s house in Van Buren matches a cartridge pulled from Graham’s body. Graham had been investigating a fatal traffic accident that happened last November when he was killed. Shockley was suspected of being involved and was arrested in that case after Graham’s death and was then identified as a “person of interest” in the Graham case.
