US inmate dies of heart attack after botched execution, 2nd inmate's execution delayed

WASHINGTON (AFP) - An American murderer died of a heart attack on Tuesday more than 40 minutes after his execution was halted due to a botched lethal injection, leading Oklahoma to postpone the execution of a second inmate.

Convicted murderer and rapist Clayton Lockett was administered a new, untested three-drug protocol that included a sedative, an anesthetic and a lethal dose of potassium chloride in what would have been the central state's first double execution in 80 years.

But Oklahoma Department of Corrections director Robert Patton ordered the execution of Lockett stopped about three or four minutes after the start of the injection at 6.23pm, citing a "vein failure", a prisons spokesman said.

Lockett died of a "massive heart attack" at 7.06pm after receiving all three drugs, spokesman Jerry Massie said. Even though he was administered the injection, "the drugs didn't go into the system", the spokesman added.

Oklahoma halted the execution of Clayton Lockett on April 29, 2014 due to problems with its lethal injection, but the inmate later died of an apparent heart attack. -- FILE PHOTO: REUTERS
