An Italian jury has overturned the murder conviction of Amanda Knox, a Seattle woman convicted four years ago of killing her roommate. Knox, a university student studying abroad, was accused of participating in the murder of a British student, Meredith Kercher, in 2007. After a report that called the forensic evidence into question, the jury freed both Knox and her then-boyfriend, Raffaele Sollecito, who was convicted of the same crime. The third person convicted of the murder, Rudy Guede, already had his conviction upheld on appeal. “I did not kill. I did not rape. I did not steal. I was not there. I was not present at this crime,” said Knox, who was described as tearful when the new verdict was announced.
