Seems as though Amanda Knox has the world by the tail. There she was yesterday, strolling around her old UW haunts, listening to music on her headphone, chatting on her cell phone, doing a little shopping. All the while, a lucrative book deal appears imminent, a memoir that could fetch her a cool million. And then, bummer: Italian prosecutors want that murder conviction reinstated.Prosecutors today appealed to Italy’s highest court, filing a 112-page brief more than four months after an appeals court threw out the convictions against her and ex-beau Raffaele Sollecito for the Nov. 1, 2007 stabbing death of Meredith Kercher, a 21-year-old British student.Prosecutor Giovanni Galati said he is “very convinced” that Sollecito and Knox committed the crime and that the appeals sentence must be thrown out, saying it was full of “omissions and many errors,” the news agency ANSA reported.The prosecutors’ appeal, which was expected, marks the third and final stage in the criminal case against Knox and Sollecito.The two were found guilty in a lower court of slaying Kercher, in what prosecutors described as a sex-fueled attack, and sentenced to 26 and 25 years respectively. An appeals court then said the evidence did not hold up, freeing Knox to return home to Seattle last October after serving four years in prison.The high court, however, cannot hear new evidence and must make its decision based on what’s been submitted in earlier trials.What crushed the prosecution’s case was a court-ordered DNA review that blew holes in the crucial genetic evidence used to convict Knox and Sollecito.Knox’s book — which some publishers are steering clear of because of lingering doubts over her version of events in Perugia — will hinge largely on diaries she wrote in jail.
