American student killer Amanda Knox broke down in an Italian courtroom on Saturday after lawyers began questioning her on the DNA evidence linking her to the murder of Meredith Kercher. Knox read from a note in Italian, apologizing to Kercher's family and friends. "I would like to say that I am sorry that Meredith is not here. What you're going through and what Meredith went through is incomprehensible and unacceptable," Knox said in court. "I am unjustly convicted," she added. "I will never get used to this broken life.” Knox also apologized to Patrice Lumumba for blaming him as the possible murderer during the 2007 police interrogation. The next hearing for the appeal trial is set for December 18 and lawyers say a verdict on whether Knox will receive a life-sentence will be determined by February or March.
