She will walk free from Capanne prison, outside Perugia, after serving four years for a crime that the appeal court ruled she did not commit.
Earlier she had told the court in fluent Italian: "I did not kill, I did not rape, I did not steal. I was not there."
Pleading with the jury, she added: "I am not who they say I am. The perversion, the violence, the lack of respect for life - I did not do the things they are saying I did."
