The guard performed the process of placing the straps and belts. Then, a metal headpiece was then put on the prisoner’s head. When everyone was out of the room, the open electrical system was turned on. The first current was applied for 15 seconds, 2000 volts. The second current was applied for 20 seconds. At this point, the prisoner’s body will be convulsed. Electrocution leads to paralysis of the brain’s respiratory centers and stops the muscles pumping the heart. Sometimes the body will become very hot, even burnt, and the eyeballs protrude.
