the appeal hearing was under way. by now, they had both been imprisoned for four years. raffaele sollecito shaved his head. knox rarely smiled. knox's family said the couple who had met just eight days before the murder hadn't communicated since their arrest. march 26th, 2011, amanda mouths to raffaele are you okay. it is a tender moment in what would be a strange hearing. amanda knox's attorney cross-examine an old witness. he is the homeless man who lived in this park and originally told the court he saw amanda and raffaele near the crime scene the night of the murder. before any testimony, cameras are ushered out of the court, and police bring in a star prosecution witness that the jury would find laughable. the homeless heroin addict could no longer remember the exact night he saw the couple. he was confused. it could have been halloween.
