A botched execution in Arizona is not stopping Missouri from moving forward with its own. The Missouri Supreme Court on Thursday set a September execution date for convicted killer Leon Taylor. Taylor is scheduled to die Sept. 10 at the state prison in Bonne Terre for killing a suburban Kansas City service station attendant during a 1994 robbery. Authorities say he tried to kill the victim’s 8 year old stepdaughter, too, but the gun misfired. Missouri has executed six men this year. Only Florida and Texas, with seven each, have executed more. Another execution is scheduled for Aug. 6, when Michael Shane Worthington is scheduled to be put to death for the rape and killing of a suburban St. Louis neighbor in 1995.
