Roberto Girón Mendoza and Pedro Castillo were two Guatemalan men convicted of murder and executed, with their deaths by firing squad occurring on 13 September 1996. It was the first official firing squad execution in Guatemala since 1983. It was also the first execution to occur in Latin America, with the exception of Guyana and the Caribbean, in a span of over ten years.
The executions occurred outside of the Canada Penal Farm (Granja de Canadá), in Escuintla, Guatemala. The men had raped and murdered four-years-old Sonia Marisol Alvarez García on 19 April 1993. This execution was broadcast on live television.
The men survived the initial volleys of bullets, so after a doctor had confirmed they were alive a squad leader killed each man by firing a bullet into their heads. The resulting controversy caused the Guatemalan legislature to change the method of execution to lethal injection.
Their executions were filmed by the press. The executions were featured in the 1998 shockumentary film, Banned from Television.
