The process was usually carried out by single executioner, usage of firing squads being limited to wartime executions. The most common method was to make the convict walk into a dead-end room, and shoot him from behind in the back of the head with a handgun. In some cases, the convict could be forced down on his knees. Some prisons were rumored to have specially designed rooms with fire slits, while in some Georgian prisons during the 1990s, the convict was tied to the floor, his head against a blood draining hole. Another method was to make the convict walk out of the prison building, where he was awaited by the executioner and a truck with the engine and headlamps turned on. The lights blinded and disoriented the convict, while the noise of the engine muffled the shot.
