Amanda Knox, cleared of the murder of British student Meredith Kercher, on Tuesday thanked supporters who believed in her innocence as she prepared to return home to the United States after four years in jail.
The family of British student Meredith Kercher said on Tuesday their ordeal would not end until they found out the truth about her murder, after Amanda Knox and her former boyfriend Raffaele Sollecito were acquitted by an Italian appeals court.
Stephanie Kercher, Meredith's sister, said they would first wait for the court's written explanation of Monday's verdict.
"Once we've got the reasons behind the decisions for this one, then we can understand why they have been acquitted of it and work toward finding those who are responsible," she told a news conference.
"That's the biggest disappointment, not knowing still and knowing that there is someone or people out there who have done this," she said.
The acquittal of Knox and Sollecito leaves Rudy Guede, an Ivorian drifter and drug dealer, as the only person convicted of the killing which investigators believe was committed by more than one person.
