Execution botched in Oklahoma, inmate later dies of heart attack

Clayton Lockett

McALESTER, Okla. — Oklahoma authorities stopped one execution Tuesday and postponed another scheduled later in the day after botching the delivery of drugs.

Convicted murderer Clayton Lockett was sedated and then given the second and third drugs in the protocol, Oklahoma Department of Corrections Director Robert Patton told reporters.

“There was some concern at that time that the drugs were not having the effect, so that doctor observed the line and determined that the line had blown,” he said.

When asked what he meant by “blown,” Patton said that Lockett’s vein had “exploded.”

“I notified the attorney general’s office, the governor’s office of my intent to stop the execution and requested a stay for 14 days for the second execution scheduled this afternoon,” said Patton.

Lockett later suffered what appeared to be a heart attack and died, the director said.

A reporter from Oklahoma City TV station KFOR was one of the witnesses to the execution attempt. Read her timeline of the events here.
