Amanda Knox, the American charged and convicted of the 2007 murder of her British roommate Meredith Kercher, faces a 28-and-a-half-year sentence if the Court of Cassation upholds the conviction. Her ex-boyfriend Raffaele Sollecito faces a 25-year sentence if the appeal is denied.

Knox is waiting for the ruling in her hometown of Seattle. As HNGN previously reported, Knox works as a writer for the West Seattle Herald. Her attorney, Carlo Dalla Vedova, said Knox is "worried, very worried," according to News Day. A decision is expected Wednesday or Thursday. Sollecito is waiting at the court, but Knox has vowed never to return willingly to Italy.

Knox and Sollecito were found guilty in Perugia in 2009, but freed in 2011 after an appellate court overturned the convictions. Knox had spent four years in prison during the whole ordeal. 2013 found the couple back in an appellate court in Florence after the Court of Cassation vacated the acquittals.

The appeals court decided that Knox and Sollecito carried out the murder with Rudy Hermann Guede, from the Ivory Coast. Guede is serving a 16-year sentence for his role in the killing and sexual assault. The judge who presided over the last appeal believes that Knox was the one who delivered the fatal stab wound. He wrote that Knox wanted to "humiliate the victim," according to News Day.

Knox considers the reversal unjust and the result of an "overzealous and intransigent prosecution," ''narrow-minded investigation" and coercive interrogation, according to News Day.
