Amanda Knox: Does the Countdown to Freedom Begin This Weekend?

In the final hours before the verdict in the appeal trial of Amanda Knox, the now 24-year-old American convicted in 2009 with two others of murdering her roommate, Elizabeth Vargas reports the very latest bombshells in court from Perugia, Italy. For the past week in an underground medieval courtroom, the closing arguments in Knox's appeal have been unfolding before a jury of two judges, six jurors and a worldwide audience of millions. The proceedings have been intense - the prosecution showing images of the fatal wounds to the victim, Knox's former roommate Meredith Kercher; the defense insisting that the young American is herself a victim of shoddy police work and an overzealous prosecution. As Amanda and her family wait for word that could mean freedom, or a life sentence, Vargas, who has been covering the story from the beginning, reveals never-before-seen letters from Knox to her family, new interviews and access to the investigation, and uncovers details about the prosecutor's questionable past and motives.
