SEATTLE - Finally cleared of involvement in her roommate's 2007 murder in Italy, Amanda Knox says she will work on behalf of the wrongly convicted.
Knox writes in a letter published Friday in that the kindness of friends, family and strangers has sustained her in the seven-plus years since she was arrested in Meredith Kercher's death of in Perugia.
She says she knows she must give back.
Knox writes that she's lucky she had the backing of lawyers, DNA experts and former FBI investigators who saw the injustice in her case. She says countless other wrongfully convicted people lack that support, and she wants to work to give them a voice.
Italy's highest court exonerated Knox and her former Italian boyfriend March 27.
