WASHINGTON (AP) - New Supreme Court Justice Samuel Alito split with the court's conservatives Wednesday night, refusing to let Missouri execute a death-row inmate contesting lethal injection. Alito, handling his first case, sided with inmate Michael Taylor, who had won a stay from an appeals court earlier in the evening. Chief Justice John Roberts and Justices Antonin Scalia and Clarence Thomas supported lifting the stay, but Alito joined the remaining five members in turning down Missouri's last-minute request to allow a midnight execution.
