Many assassins have been killed in the act, such as Rigoberto López Pérez, who shot Nicaraguan dictator Anastasio Somoza García in 1956. Claus von Stauffenberg tried to kill Adolf Hitler on 20 July 1944, was sentenced to death by an impromptu court martial and executed a few hours after the attempted murder. Others were prosecuted for the killing: Antonio de la Maza and his conspirators were executed after their shooting of Rafael Trujillo, dictator of the Dominican Republic in 1961, as was Kim Jaegyu, who shot South Korean dictator Park Chung-hee in 1979. Five of the members of Young Bosnia who were involved with the assassination of Archduke Franz Ferdinand in Sarajevo were sentenced to death by hanging, while eleven were sentenced to various years in prison, including Gavrilo Princip who fired the fatal shot. Khalid Islambouli was one of three members of Egyptian Islamic Jihad executed for the assassination of Anwar Sadat, the autocratic President of Egypt in 1981. Even both Hipparchus's assassins were themselves killed, Harmodius on the spot and Aristogeiton after being tortured, and the major conspirators in the plot to kill Caesar were likewise killed or forced to commit suicide.
