Last year, Knox was convicted and sentenced to 26 years in prison for the murder of her British roommate Meredith Kercher. Also convicted of the same charges was Raffaele Sollecito, an Italian who is Knox’s former boyfriend. He was sentenced to 25 years in prison. Both deny wrongdoing, and have appealed the verdict.
