The authorities at Soledad Prison fostered racial hostility, enforcing rigid segregation in the maximum-security wing. Despite mounting tension, on January 13, 1970, fourteen African-American and two Euro-American prisoners were released into a new recreation yard for the first time in months. No guard accompanied them, but one—renowned for his marksmanship—stood armed in the gun tower overlooking the yard. The events that followed remain unclear. According to prison officials, a fistfight broke out, prompting the guard to fire four shots.
The three African-American prisoners were killed, while one Euro-American prisoner was wounded. No alarm whistle was sounded, no warning shot was fired, and no tear gas was used. In the aftermath, thirteen African-American prisoners launched a hunger strike, demanding an investigation. On January 16, 1970, a Monterey County grand jury convened and declared the deaths of Nolen, Edwards, and Miller a “justifiable homicide.” No African-American prisoners—including those present in the recreation yard—were allowed to testify. Within thirty minutes of the grand jury’s ruling being broadcast over the prison radio, a Euro-American guard was found dying in another maximum-security wing, beaten and thrown from a third-floor tier to the television room below.
However, with the assistance of a state senator, Clutchette’s mother secured legal counsel, initiating one of the most extensive legal defenses in U.S. history. According to their attorneys, Jackson, Drumgo, and Clutchette were charged with murder not due to substantial evidence, but because prison authorities had previously labelled them as militants.
Within weeks, the Soledad Brothers’ case became a political cause célèbre, drawing support from a diverse group of celebrities, writers, and activists. Notable supporters included Julian Bond, Kay Boyle, Marlon Brando, Jane Fonda, Noam Chomsky, Lawrence Ferlinghetti, Allen Ginsberg, Tom Hayden, William Kunstler, Jessica Mitford, Linus Pauling, Pete Seeger, Benjamin Spock, and Angela Davis.
