article: Amanda Knox has said she will work to overturn miscarriages of justice after being sensationally cleared of the murder of Meredith Kercher. Knox said she would lobby on behalf of other innocent people who were jailed ‘because I know how a wrongful conviction can destroy one’s life.’ The American, known as Foxy Knoxy, and former boyfriend Raffaele Sollecito served four years for the 2007 murder of the 21-year-old exchange student. Scroll down for video . Cleared: Amanda Knox is pledging to work for others who claim to have suffered miscarriages of justice . They were freed on appeal in 2011 and Knox immediately returned to the US where she rebuilt her life finding love with ex school friend Colin Sutherland. Then last year an appeal court overturned their acquittal finding the pair guilty of the murder again. Victim: Meredith Kercher was killed while in her bed in Perugia in 2007 . In a shocking twist Italy’s highest court last week conclusively cleared the former couple. A third man Rudy Guede is serving a 16 year sentence for the murder. In an open letter to the Seattle Times, Knox said she was ‘relieved and grateful’ that the court had found her innocent. She said she felt ‘lucky’ to have had the support of those belief ‘helped me survive when I was at my most vulnerable and almost entirely lost.’ She only survived the seven year ordeal she said ‘because my dear family gave up their lives to be with me in Italy, because scores of friends donated their resources, because my lawyers worked tirelessly to bring attention to the evidence that exonerated me, because strangers — from world-renowned DNA experts to former FBI crime-scene investigators to everyday citizens — saw the injustice in my case and spoke out.' Because of this she said she felt compelled to ‘give back’. She said: ‘I am all too aware of how lucky I am to have received such strong support. I am also aware that countless other wrongfully convicted persons do not have such support. I will work to give a voice to those individuals. I will do this because I know how a wrongful conviction can destroy one’s life.’ Knox -who was reportedly paid £2.7million ($4million) for her 2013 book Waiting to Be Heard -could be in line for millions in compensation for time wrongly spent in prison. It is thought the amount could reach seven figures.
