The deaths of Guillermo Sanchez and Gildardo Sanchez occurred on July 16, 1970, when the Los Angeles Police Department raided their apartment at 826 E. 7th St. in downtown Los Angeles in the U.S. state of California. The cousins were both shot and killed during the raid. Guillermo Beltran Sanchez was 22 years old, Gildardo Alcazar Sanchez was 21. The incident was dubbed the mistake shooting by the newspapers. Journalist Ruben Salazar, who would himself be killed by an L.A. County sheriff's deputy in August 1970, featured interviews with survivors of the raid on KMEX. The following year the militant Chicano Liberation Front claimed responsibility for bombing Los Angeles City Hall with a telephone message that stated that the bomb was "in memory of the Sanchez brothers."
