Murder of Lynn Gray (First Fed'l S & L, Abilene, 3/18/80)
Lucas confessed (as summarized in a federal report). Authorities hoped that - for once - forensic evidence might corroborate a Lucas confession. Unfortunately, they could only find 5 "points" of similarity to fingerprints at the scene, not enough for a match. As it turned out, Lucas was in Florida at the time of this Texas murder.
