prisoners (Cleveland Edwards and Alvin Miller) during a yard riot with members of the Aryan Brotherhood, killing all three. Following Nolen's death, Jackson became increasingly confrontational with corrections officials and spoke often about the need to protect fellow inmates and take revenge on correction officers, employing what Jackson called "selective retaliatory violence". On January 17, 1970, Jackson, Fleeta Drumgo and John Clutchette were charged with murdering a corrections officer, John V. Mills, who was beaten and thrown from the third floor of Soledad's Y wing. This was a capital offense and a successful conviction would have put Jackson in the gas chamber. Mills was purportedly killed in retaliation for the shooting deaths of three inmates by Miller the previous year. Miller had not been charged with any crime, as a grand jury ruled his actions during the prison fight justifiable homicide. Marin County courthouse incident On August 7, 1970, George Jackson's 17-year-old brother Jonathan P. Jackson burst into a Marin County courtroom with an automatic weapon, freed prisoners James McClain, William A. Christmas and Ruchell Magee, and took Judge Harold Haley, Deputy District Attorney Gary Thomas, and three jurors hostage to demand the release of the "Soledad Brothers". Police killed Haley, Jackson, Christmas and McClain as they attempted to drive away from the courthouse. Eyewitness testimony suggests Haley was hit by fire discharged from a sawed-off shotgun that had been fastened to his neck with adhesive tape by the abductors. Thomas, Magee and one of the jurors were wounded. The case made national headlines. Angela Davis, who owned the weapons used in the hostage taking, was later acquitted of conspiracy, kidnapping, and murder. A possible explanation for the gun connection is that Jonathan Jackson was her bodyguard. Magee, the sole survivor among the attackers, eventually pleaded guilty to aggravated kidnapping and was sentenced to life imprisonment in 1975. Magee has been imprisoned for over 50 years. Prison escape and death On August 21, 1971, Jackson met with attorney Stephen Bingham at San Quentin prison to discuss a civil lawsuit that Jackson had filed against the California Department of Corrections. After the meeting, Jackson was being escorted by officer Urbano Rubiaco back to his cell when Rubiaco noticed a metallic object in Jackson's hair, later revealed to be a wig, and ordered him to remove it. Jackson then pulled a Spanish Astra 9 mm pistol from beneath the wig and said:
