So Rubin was free － but his joy was short-lived. In a new trial, late in 1976, Bello changed his testimony yet again. The prosecution also put forward a 'racial revenge' theory to explain the shootings: they said that Rubin killed the white bartender, to avenge the shooting, six hours earlier, of a black bar-owner by a white man. What's more, some people who had been alibi witnesses on Rubin's side, now said he had asked them to lie for him. Rubin and his friend were sent back to prison. As before, he spent his time reading and studying, and he had little contact with the inmates and guards around him. But now his hopes for release had been crushed.
But just when everything seemed lost, Rubin struck up an unexpected friendship with a fifteen-year-old boy, Lesra Martin. Lesra was a New York boy who had moved to live in a commune in Toronto, and he had picked up Rubin's autobiography at a garage sale. He visited Rubin in prison, and when he told the other commune members about his visit, they decided to investigate Rubin's case. They spoke with him on the phone, and sent him food, clothes, and even a TV set.
In 1983, the Canadian group began to work with Rubin's defense lawyers, carefully going through the thousands of pages of evidence which had built up, showing how the prosecution had concealed and manipulated evidence. But should they appeal again to the New Jersey Supreme Court, which had already rejected an earlier appeal for a third trial, or should they appeal to the Federal Court ? Rubin himself decided to take the high-risk option and appeal to the Federal Court. If this appeal failed, there would be nothing left － it would mean imprisonment for life.
