SEATTLE (AP) -- Amanda Knox and her family say they're not worried about a decision by Italian prosecutors to appeal her acquittal on charges of killing her roommate in 2007.
A statement released by a family spokesman says her most recent trial clearly established her innocence. It calls the appeal "simply another example of harassment by the prosecution against Amanda."
Knox and her former boyfriend, Raffaele Sollecito, served four years in prison before an appeals court overturned their convictions last fall. Knox was a foreign exchange student in Italy when Meredith Kercher was killed. She returned to Seattle after her release from custody.
