He had been stricken with prostate cancer in Toronto, the New Jersey native’s adopted home. John Artis, a longtime friend and caregiver, said Carter died in his sleep.
Carter spent 19 years in prison for three murders at a tavern in Paterson, N.J., in 1966. He was convicted alongside Artis in 1967 and again in a new trial in 1976.
Carter was freed in November 1985 when his convictions were set aside after years of appeals and public advocacy. His ordeal and the alleged racial motivations behind it were publicized in Bob Dylan’s 1975 song “Hurricane,” several books and a 1999 film starring Denzel Washington, who received an Academy Award nomination for playing the boxer turned prisoner.
Carter’s murder convictions abruptly ended the boxing career of a former petty criminal who became an undersized middleweight contender largely on ferocity and punching power.
