An Italian appeals court convicted former exchange student Amanda Knox and her ex-boyfriend Raffaele Sollecito on murder charges Thursday night. Prosecutors said the couple had killed Meredith Kercher in 2007. They were convicted two years later of murder, but those charges were overturned on appeal in 2011. It is unlikely Knox, who lives in Seattle, Washington, will return to Italy to serve additional prison time because U.S. law dictates that a person cannot be tried twice on the same charge, a legal expert tells CNN.
