Medell Banks, a retarded, poor black man from Butler, Ala., is serving a 15-year sentence for manslaughter as a result of his confession that he killed his newborn baby in 1999, despite strong evidence that there was never a baby in the first place. While in jail in an earlier incident, Banks' estranged wife claimed she was pregnant, hoping for lenient treatment, but refused to be examined except cursorily by a local doctor who said he thought he heard a fetal heartbeat. When Mrs. Banks' "baby" vanished, authorities assumed it had been born and killed. (Mrs. Banks had been sterilized four years earlier, and doctors say she remains sterile.) (In August, a state appeals court ordered a new trial for Banks, but he remains in prison through the obstinacy of the district attorney, Robert Keahey.) [New York Times-AP, 8-12-02, 8-15-02]
