The inmate Clayton Lockett, 38, convicted of first-degree murder, rape, kidnapping and robbery for a 1999 crime, died of an apparent massive heart attack about 40 minutes after the procedure started and was halted by director. “It was a horrible thing to witness. This was totally botched,” said Lockett’s attorney, David Autry. It was the first time Oklahoma used the sedative drug midazolam as the first element in its execution drug combination, after drugmakers have stopped selling their products to prisons and corrections departments. Clayton was breathing heavily, writhing, clenching his teeth and straining to lift his head off the pillow. The blinds were lowered to prevent those in the viewing gallery from watching what was happening in the death chamber. It’s unclear what was the problem and an investigation was ordered by the Governor Mary Fallin. But the appearance that Clayton Lockett was tortured to death, in violation of the U.S. Constitution, it ‘s expected to have national implication being considered without doubts in any future debates about human executions.
