The Angola Three are three prison inmates – Robert Hillary King (born Robert King Wilkerson), Albert Woodfox and Herman Wallace – who were put in solitary confinement in Louisiana State Penitentiary, a.k.a. Angola Prison, after the 1972 killing of a prison guard. Robert King spent 29 years in solitary confinement before his conviction was overturned and he was released. Wallace, before being released October 1, 2013, and Woodfox spent 40 years of solitary confinement as of 2013. The prisoners have been the subject of two documentary films and international attention. In July 2013 Amnesty International called for the release of 71-year-old Herman Wallace, who had advanced liver cancer. He was released October 1, 2013, and died three days later, on October 4, 2013.
On November 20, 2014, Albert Woodfox, the longest-standing solitary confinement prisoner in the US, had his conviction overturned by the US Court of Appeals. He has not yet been released
