FILE - This April 21, 1993 file photo shows inmates raising their hands in surrender as armed guards watch on the recreation yard of the Southern Ohio Correctional Facility in Lucasville, Ohio. In the 20 years since the nation's longest deadly prison riot broke out in Lucasville, no interviews have been granted with the five men sentenced to death in the killing of a guard. Yet time has brought new evidence and insights that will dominate events marking the 20th anniversary of the 11-day siege of April 1993. (AP Photo/Lennox McLendon, File)
