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.
Although never a world champion, Carter went 27-12-1 with 19 knockouts, memorably stopping two-division champ Emile Griffith in the first round in 1963. He also fought for a middleweight title in 1964, losing a unanimous decision to Joey Giardello.
In June 1966, three white people were shot by two black men at the Lafayette Bar and Grill in Paterson. Carter and Artis were convicted by an all-white jury largely on the testimony of two thieves who later recanted their stories.
Carter was granted a new trial and briefly freed in 1976, but sent back for nine more years after being convicted in a second trial.
Thom Kidrin, who became friends with Carter after visiting him several times in prison, told The Associated Press the boxer "didn't have any bitterness or anger — he kind of got above it all. That was his great strength."
"I wouldn't give up," Carter said in an interview on PBS in 2011. "No matter that they sentenced me to three life terms in prison. I wouldn't give up. Just because a jury of 12 misinformed people ... found me guilty did not make me guilty. And because I was not guilty, I refused to act like a guilty person."
Dylan became aware of Carter's plight after reading the boxer's autobiography. He met Carter and co-wrote "Hurricane," which he performed on his Rolling Thunder Revue tour in 1975. The song concludes: "That's the story of the Hurricane/But it won't be over till they clear his name/And give him back the time he's done/Put him in a prison cell but one time he could-a been/The champion of the world."
Muhammad Ali spoke out on Carter's behalf. Advertising art director George Lois and other celebrities also worked toward Carter's release.
With a network of friends and volunteers also advocating for him, Carter eventually won his release from U.S. District Judge H. Lee Sarokin, who wrote that Carter's prosecution had been "predicated upon an appeal to racism rather than reason, and concealment rather than disclosure."
Born on May 6, 1937, into a family of seven children, Carter struggled with a hereditary speech impediment and was sent to a juvenile reform center at 12 after an assault. He escaped and joined the Army in 1954, experiencing racial segregation and learning to box while in West Germany.
Carter then committed a series of muggings after returning home, spending four years in various state prisons. He began his pro boxing career in 1961 after his release, winning 20 of his first 24 fights mostly by stoppage.
Carter was fairly short for a middleweight at 5-foot-8, but he was aggressive and threw a lot of punches. His shaved head and menacing glower gave him an imposing ring presence, but also contributed to a menacing aura outside the ring. He was quoted as joking about killing police officers in a 1964 story in the Saturday Evening Post, which was later cited by Carter as a cause of his troubles with police.
Carter boxed regularly on television at Madison Square Garden and overseas in London, Paris and Johannesburg. Although his career appeared to be on a downswing before he was implicated in the murders, Carter was hoping for a second middleweight title shot.
Carter and Artis were questioned after being spotted in the area of the murders in Carter's white car, which vaguely matched witnesses' descriptions.
