Lawyers for Troy Davis, Stephen Marsh and Danielle Garten, in car, are turned away at the Georgia Diagnostic Prison Wednesday, Sept. 21, 2011 as they tried to gain access to give a polygraph test to Troy Davis before he is scheduled to be executed Wednesday night. Davis, who has always maintained his innocence, sits on death row for the 1989 murder of off-duty Savannah Police Officer Mark Allen MacPhail. Supporters of Davis are urging Savannah's top prosecutor to intervene with just hours to spare before Davis' scheduled execution.(AP Photo/Atlanta Journal-Constitution, John Spink) MARIETTA DAILY OUT; GWINNETT DAILY POST OUT less
