Italy's highest court will decide later whether to uphold Amanda Knox's conviction for murdering a British student.
Meredith Kercher was stabbed to death in 2007 while studying in Perugia in Italy.
Her flatmate Amanda Knox and her then boyfriend spent four years in jail for the murder but were acquitted on appeal in 2011.
Knox returned to the US before an appeals court reinstated the guilty verdict - that decision could be upheld today.
But legal experts are split on whether Italy will be able to extradite her.
