On April 23, 2011, 48 HOURS MYSTERY correspondent Richard Schlesinger reported the story, "Grave Injustice," of Anthony Graves, a Texas man who walked free in October 2010 when it was proven that he had been wrongfully convicted in 1994 on six counts of capital murder. Formerly known as Inmate #999127, Graves was on death row when a group of journalism students from the University of St. Thomas in Houston began looking at his case. After four years of investigating, they uncovered the truth: Anthony Graves was an innocent man. Now correspondent Richard Schlesinger details this complicated miscarriage of justice. He speaks with Graves, his family and two former prosecutors who battle over the truthfulness of the evidence. Schlesinger also talks with the former journalism students and members of the media who helped shed light on this injustice.
