PERUGIA, ITALY -- An Italian jury has begun deliberations in the yearlong trial of American student Amanda Knox, who is charged with murdering her British roommate.

The eight members of the jury, including two judges, sequestered themselves Friday in the courtroom of this Medieval city. A verdict can come any time, but it is not expected before Friday night, according to court officials.

Knox and her co-defendant, Raffaele Sollecito of Italy, are charged with murder and sexual assault in the 2007 slaying of Meredith Kercher. Knox and Sollecito were dating at the time.

The prosecutors are seeking a life sentence. Both defendants deny wrongdoing.

In an emotional statement to the court Thursday, Knox said she does not want the "mask of an assassin" forced on to her.
