His sentence was set aside after he had spent nearly 20 years in prison. The film concentrates on Rubin Carter's life between 1966 and 1985. It describes his fight against the conviction for triple murder and how he copes with nearly 20 years in prison.
A parallel plot follows Lesra Martin, an underprivileged Afro-American youth from Brooklyn, now living in Toronto. In the 1980s, the child becomes interested in Carter's life and circumstances after reading Carter's autobiography. He convinces his Canadian foster family to commit themselves to Carter's case. The story culminates with Carter's legal team's successful pleas to Judge H. Lee Sarokin of the United States District Court for the District of New Jersey.
In 1966, Rubin "The Hurricane" Carter was a top-ranked middleweight boxer, expected by many fans to become the world's greatest boxing champion. When three victims, specifically the club's bartender and a male and a female customer, were shot to death in a bar in Paterson, New Jersey, Carter and his friend John Artis, driving home from another club in Paterson, were stopped and interrogated by the police.
Although the police asserted that Carter and Artis were innocent and thus, "were never suspects," a man named Alfred Bello, a suspect himself in the killings, claimed that Carter and Artis were present at the time of the murders. On the basis of Bello's testimony, Carter and Artis were convicted of the triple homicide in the club, Carter was given three consecutive life sentences. 
Question: What's the full name of the person who made the accusation that landed Carter in prison for nearly 20 years?
Output (English): Alfred Bello.
