Overview

• Marvin Haynes, who has spent nearly two decades in prison for a deadly 2004 flower shop robbery, insists he is '100 percent innocent'.
• Judge William Koch is re-examining Haynes' conviction, with hearings set to continue until December 20.
• No physical evidence tied Haynes to the crime and he didn't match the physical description that witnesses provided to investigators.
• Several people who testified at Haynes' 2005 trial have since signed affidavits recanting their statements.
• Haynes' lawyers argue that he was wrongfully convicted based on faulty eyewitness identification and improper police lineups.
