Italy's highest court has overturned the murder convictions of American Amanda Knox and her former Italian boyfriend, Raffaele Sollecito, ending a years-long high-profile case.
Friday's ruling by the Court of Cassation ends the legal battle by Knox and Sollecito, who have long maintained their innocence in the death of British student Meredith Kercher on November 1, 2007.
Knox had been awaiting the verdict in the U.S. city of Seattle, Washington. David Marriott, a representative for Knox, told the Reuters news agency that she was "overjoyed" by the court's action.
Friday's decision overturned last year's conviction by a Florence appeals court. The Court of Cassation also declined to order another trial.
Knox and Sollecito have been free since 2011, when an appeals court first overturned their convictions and sentences of 26 and 25 years. A criminal court then overturned that acquittal and ordered a retrial, at which they were convicted again in 2014.
Prosecutors had said Kercher, a British student who lived with Knox when the two were exchange students in Perugia, Italy, was killed in their house when a sex game turned violent.
A third suspect in the case, former drug dealer Rudy Guede, was given a 30-year prison sentence, which was later reduced to 16 years,
