On August 7, 1970, heavily armed 17-year-old African-American high-school student Jonathan Jackson, whose brother was George Jackson, one of the three Soledad Brothers, gained control of a courtroom in Marin County, California. He 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 defendants away from the courtroom, one of the defendants, James McClain, shot at the police. The police returned fire. The judge and the three black men were killed in the melee; one of the jurors and the prosecutor were injured. Although the judge was shot in the head with a blast from a shotgun, he also suffered a chest wound from a bullet that may have been fired from outside the van. Evidence during the trial showed that either could have been fatal. Davis had purchased several of the firearms Jackson used in the attack, including the shotgun used to shoot Haley, which she bought at a San Francisco pawn shop two days before the incident. She was also found to have been corresponding with one of the inmates involved.
