The Angola 3 refers to three men convicted of murdering a prison guard at the Louisiana State Penitentiary more than 40 years ago, in 1972. Robert King, Herman Wallace, and Albert Woodfox were accused of the crime and then held mostly in solitary confinement for decades. King’s conviction was overturned in 2001. In October, 2013, a federal judge released Herman Wallace, saying he did not receive a fair trial. He died three days later in New Orleans from liver cancer. Now there’s one member of the Angola 3 still in jail: Albert Woodfox. Laine Kaplan Levenson reports on continued efforts to use the story of the Angola 3 to combat long-term solitary confinement in prisons.
