Amanda Knox has been declared guilty of murdering her former roommate, Meredith Kercher, and was sentenced to 26 years in prison by an Italian jury Friday night. The Italian jury declared Knox guilty of all six counts she faced, including tampering with a crime scene and theft. The 22-year-old has been on trial for 11 months in a case that has gripped international media attention. Prosecutors argued that Knox convinced her boyfriend and another man to hold her British roommate down and sexually assault her before she cut her throat. She was led from the courtroom crying, and her lawyer says they will appeal the decision.
