After Kennard published a letter in the local paper about integrated education, the Mississippi State Sovereignty Commission, a state-supported agency, conspired to have him arrested on false charges. He was convicted and sentenced to seven years at Parchman Penitentiary, the state's notorious high-security prison. He became terminally ill with cancer. The state governor refused to pardon him, but released him on parole in January 1963. Kennard died that year in July. After publication in 2005 of evidence that Kennard had been framed, supporters tried to secure a posthumous pardon for him, but Governor Haley Barbour refused. Supporters gained Barbour's cooperation in petitioning the court to review Kennard's case, and in 2006, his conviction was overturned completely.
