Amanda Marie Knox is an American writer and activist who spent almost four years in an Italian prison accused of the murder of Meredith Kercher on November 1, 2007. Knox, then a 20 year old exchange student, had spent the night with her boyfriend, Raffaele Sollecito; upon returning to her flat, she discovered her roommate Kercher dead. Knox became a suspect and during an extended interrogation—the conduct of which is a matter of dispute—she implicated herself, Sollecito, and her employer, Patrick Lumumba. They were charged with the murder, but forensic evidence from Kercher's body identified Rudy Guede, a local petty criminal. Although originally denying that Knox had any involvement, Guede later incriminated her as the killer. Guede was tried separately and convicted of participating in the killing. At the subsequent trial of Knox and Sollecito, American legal commentators were disturbed by the latitude given to the prosecution.
