'My innocence propelled me forward': Amanda Knox pledges to help the wrongly convicted

After finally being cleared of involvement in her roommate's 2007 murder in Italy, Amanda Knox says she will work on behalf of the wrongly convicted.

Ms Knox wrote in a letter published in The Seattle Times, that the kindness of friends, family and strangers has sustained her in the seven-plus years since she was arrested over Meredith Kercher's death in Perugia.

She says she knows she must give back.

Ms Knox said she's lucky she had the backing of lawyers, DNA experts and former FBI investigators who saw the injustice in her case.

"Throughout these past seven and a half years, knowledge of my innocence propelled me forward," she wrote. 

"Your kindness sustained me. 

"I am, and forever will be, grateful to the many people who helped me survive when I was at my most vulnerable and almost entirely lost."

Ms Knox has committed to help those wrongly convicted. 

"I will work to give a voice to those individuals," she wrote. 

"I will do this because I know how a wrongful conviction can destroy one’s life and because we best honor crime victims by ensuring that the actual perpetrators are brought to justice."

Italy's highest court exonerated Knox and her former Italian boyfriend Raffaele Sollecito last week.
