Oklahoma carries out its first execution since botched one

McALESTER, OK -- Oklahoma has executed a death row inmate for killing a baby in 1997 in the state's first lethal injection since a botched one last spring.

Prison officials declared Charles Frederick Warner dead at 7:28 p.m. CST Thursday.

It was the second time Oklahoma used the sedative midazolam as part of a three-drug method, which had been challenged by Warner and other death row inmates as presenting an unconstitutional risk of pain and suffering.

Warner was originally scheduled to be executed in April on the same night as Clayton Lockett, who began writhing on the gurney, moaning and trying to lift his head after he'd been declared unconscious.
