Knox leaves Italy for US as victim's family searches for answers in brutal slaying

PERUGIA, Italy - Amanda Knox headed home to the United States a free woman Tuesday, after an Italian appeals court dramatically overturned the American student's conviction of sexually assaulting and brutally slaying her British roommate.

The family of 21-year-old victim Meredith Kercher appeared overwhelmed at the ruling, saying they were shocked and bewildered by the stunning reversal of the 2009 decision. The prosecutor said he would appeal the decision releasing Knox and her co-defendant and one-time boyfriend, Italian Raffaele Sollecito.

The case has been a cause celebre in the U.S., and a staple of British tabloids, which took to calling her "Foxy Knoxy." Throughout the four-year case, Knox was portrayed either as a femme fatale with an angel face or a naive young woman caught up in a judicial nightmare.
