A mentally impaired man was convicted; now another man is charged for the crime he was convicted of. Moore implicated himself during interrogation. Thirty-three years after conviction -- two years after Moore's death -- the case was reopened, and police charged an Emporia sex offender with the slaying. The author writes, “If Moore is cleared, it will not be the first time DNA has proved that a mentally impaired person made a false confession in a Virginia murder investigation.”
