On August 7, 1970, Jonathan Jackson, a heavily armed 17-year-old African-American high-school student, gained control over a courtroom in Marin County, California. Once in the courtroom, Jackson armed the black defendants and took Judge Harold Haley, the prosecutor, and three female jurors as hostages. As Jackson transported the hostages and two black convicts away from the courtroom, the police began shooting at the vehicle. The judge and the three black men were killed in the melee; one of the jurors and the prosecutor were injured. Davis had purchased the firearms used in the attack, including the shotgun used to kill Haley, which had been bought two days prior and the barrel sawed off. Davis was also corresponding with one of the inmates involved.
