Jonathan Peter Jackson (June 23, 1953 – August 7, 1970) was an American youth, who died of gunshot wounds suffered during his armed invasion of a California courthouse. At age 17, Jackson stormed the Marin County Courthouse with automatic weapons, kidnapping Superior Court Judge Harold Haley, prosecutor Gary Thomas, and three jurors. Escaping with the hostages, Jackson demanded the Soledad Brothers' immediate release from prison. The Soledad Brothers, a group of African American inmates facing charges for allegedly throwing a white prison guard to his death at San Quentin, included Jackson's elder brother George Jackson. None of the Soledad defendants were at the courthouse on the day of the attack.
