TORONTO -- Rubin "Hurricane" Carter, the former American boxer who became a global champion for the wrongfully convicted after spending almost 20 years in prison for a triple murder he didnt commit, died at his home in Toronto on Sunday. Sokratis Papastathopoulos Jersey . He was 76. His long-time friend and co-accused, John Artis, said Carter died in his sleep after a lengthy battle with prostate cancer. "Its a big loss to those who are in institutions that have been wrongfully convicted," Artis told The Canadian Press. "He dedicated the remainder of his life, once we were released from prison, to fighting for the cause." Artis quit his job stateside and moved to Toronto to act as Carters caregiver after his friend was diagnosed with cancer nearly three years ago. During the final few months, as Carters health took a turn for the worse, Artis said the man who was immortalized in a Bob Dylan song and a Hollywood film came to grips with the fact that he was dying. "He tried to accomplish as much as he possibly could prior to his passing," Artis said, noting Carters efforts earlier this year to bring about the release of a New York City man incarcerated since 1985 -- the year Carter was freed. "He didnt express very much about his legacy. Thatll be established for itself through the results of his work. Thats primarily what he was concerned about -- his work," Artis said. 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 centre 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. He was fairly short for a middleweight, but his aggression and high punch volume made him effective. Carters life changed forever one summer night in 1966, when two white men and a white woman were gunned down in a New Jersey Bar. Police were searching for what witnesses described as two black men in a white car, and pulled over Carter and Artis a half-hour after the shootings. Though there was no physical evidence linking them to the crime and eyewitnesses at the time of the slayings couldnt identify them as the killers, Carter was convicted along with Artis. Their convictions were overturned in 1975, but both were found guilty a second time in a retrial a year later. After 19 years behind bars, Carter was finally freed in 1985 when a federal judge overturned the second set of convictions, citing a racially biased prosecution. Artis was also exonerated after being earlier paroled in 1981. Carter later moved to Toronto and became the founding executive director of the Association in Defence of the Wrongly Convicted, which has secured the release of 18 people since 1993. Win Wahrer, a director with the association, remembers Carter as the "voice and the face" of the group. "I think its because of him that we got the credibility that we did get, largely due to him -- he was already a celebrity, people knew who he was," she said. "He suffered along with those who were suffering." Though Carter left the organization in 2005, the phone never stopped ringing with requests for him, Wahrer said. "He was an eloquent speaker, a passionate speaker. I remember the first time I ever heard him I knew I was in the presence of a man that could move mountains just by his presence and his words and his passion for what he believed in," she said. Carter went on to found another advocacy group, Innocence International. "He wanted to bring people together. That was his real purpose in life -- to get people to understand one another and to work together to make changes," said Wahrer. "It was so important for him to make a difference. And I think he did. I think he accomplished what he set out to do." Association lawyer James Lockyer, who has known Carter since they were involved in the wrongful conviction case of Guy Paul Morin, remembered how Carter called him just before sitting down with then-president Bill Clinton for a screening of his 1999 biopic "The Hurricane." The call was to ask for advice on how to bring the U.S. leaders attention to the case of a Canadian woman facing execution in Vietnam. "Even though this was sort of a pinnacle moment of Rubins life -- to sit at the White House with the president and his wife on either side of him watching a film about him -- he wasnt really thinking about himself," said Lockyer. "He was thinking about this poor woman who was sitting on death row in Vietnam that we were trying to save from the firing squad." The film about Carters life starred Denzel Washington, who received an Academy Award nomination for playing the boxer turned prisoner. On Sunday, when told of Carters death, Washington said in a statement: "God bless Rubin Carter and his tireless fight to ensure justice for all." Carters fight continued to the very end. Never letting up even as his body was wracked with cancer, Carter penned an impassioned letter to a New York paper in February calling for the conviction of a man jailed in 1985 to be reviewed -- and reflected on his own mortality in the process. "If I find a heaven after this life, Ill be quite surprised. In my own years on this planet, though, I lived in hell for the first 49 years, and have been in heaven for the past 28 years," he wrote. "To live in a world where truth matters and justice, however late, really happens, that world would be heaven enough for us all."

"I just think what it does for everybody in life is real simple," said Babcock early on Friday afternoon. "You dont give in. You just keep on keeping on. Is it going to go your way every time? No. But you choose your attitude and how you perform and how hard you dig in." Nearly four years to the day of the 2010 gold medal match in Vancouver, his team dug in with its best effort of these Olympics, snuffing out the high-powered Americans for another opportunity at gold.Barnsley defender George Williams is hoping to make it two successive summers of celebration this weekend - but for very different reasons. Last year the 23-year-old earned a degree in sports science and management at Loughborough University, four years after being released by MK Dons.Twelve months later he is one game away from becoming a Championship player as the Reds take on Millwall in the Sky Bet League 1 play-off final at Wembley on Sunday. Victory for Paul Heckingbottoms side would complete a remarkable journey for Williams, who was heartbroken at his 2012 exit from the Dons.He combined his studies with playing in non-league and the full-back got his second chance at Oakwell in December 2015 after joining from Worcester.Now the chance to earn a second Wembley win of the season - after the clubs Johnstones Paint Trophy triumph - and cap off a superb 12 months is getting Williams excited. Rob Holding Jersey. I have had a different route in the professional game, went to university and played non-league, so it means a hell of a lot to be here, he said.I graduated last year and now its nice just to focus on football. Towards the end of last season I was training and then going back to uni for lectures.I got released at 18 and Id always liked studying so I went there but my goal was to get back to full-time football and as well as that get a degree.Professional football doesnt happen for many people so I would have a career in sports science. I am glad I have done that and I will have that to fall back on whenever that day comes. Also See: Barnsley video Barnsley fixtures Barnsley stats ' ' '
