Amanda Knox, left, follows her attorney Michael Nifong as they attend a news conference held at the Seattle-Tacoma International Airport near Seattle, Washington on October 4, 2011. After spending four years in an Italian prison Knox arrived in the United States after departing Rome's Leonardo da Vinci airport. Knox's life turned around dramatically Monday when an Italian appeals court threw out her conviction in the sexual assault and fatal stabbing of her British roommate. ©2011. Jim Bryant Photo.
