(originally produced for KPFT-Houston News) Angola prison inmate and Black Panther Herman Wallace may get a chance at overturning his life sentence. At a hearing Tuesday new evidence was presented that a key prosecution witness was bribed in the 1972 trial where Wallace was implicated in the murder of a prison guard. Wallace is one of the Angola 3, a group of black panthers who have spent decades in solitary confinement in the infamous prison and former slave plantation. Christian Roselund is in Angola and has more.
