OKLAHOMA CITY, Aug. 28 (UPI) -- Clayton Lockett, the Oklahoma inmate who died after his execution was halted, was killed by the drugs given him, not a heart attack, a report released Thursday said.
The Oklahoma Department of Public Safety released the autopsy findings for what has become one of the most notorious executions this year. Oklahoma, which planned to execute a second man the same night Lockett was put to death, has extended a moratorium into next year.
