Italy's highest court is reviewing Wednesday the murder conviction of Amanda Knox, a process that could set up an extradition battle between Italy and the United States. In 2007, while Knox was living in Italy as an exchange student, her 21-year-old roommate Meredith Kercher was found dead, bearing signs of sexual assault and her throat slashed. An Italian court found Knox and her former boyfriend, Raffaele Sollecito, guilty, and they served four years in prison before they were acquitted by an appeals court in 2011. They were retried, and in January 2014 a second appellate court upheld the original conviction, sentencing Ms. Knox to 28½ years in prison and Mr. Sollecito to 25.
