Two states, Louisiana and Oregon, have laws that allow offenders of some crimes to be convicted with less than unanimous jury verdicts. The U.S. Supreme Court upheld those laws Monday when the court refused to hear the appeal of convicted Louisiana serial killer Derrick Todd Lee. Lee was convicted of second-degree murder. The jury voted 11-1 to convict. Because the verdict was not unanimous, Lee's attorneys appealed. The Supreme Court ruled in a previous case more than 30 years ago that the Constitution does not ban less than unanimous verdicts.
