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/Chris Kasson, File)
