The planned double execution for two men Tuesday in McAlester did not go according to plan.
The execution for one of the men, Clayton Lockett, began at 6:23 p.m. Lockett was not declared unconscious until 6:33 p.m. and at 6:36 p.m. he started convulsing. Witnesses said they heard him say "something's wrong" at 6:37 p.m.
At 6:39 p.m. officials lowered the blinds and announced a vein failure. Officials said the chemicals did not enter as they were supposed to.
Lockett was declared dead of a heart attack at 7:06 p.m. Lockett's attorney has reportedly called it a "botched execution" and wanted him to be taken to the hospital.
The execution for the other suspect, Charles Warner, which was scheduled for tonight at 8 p.m., has been postponed.
Gov. Mary Fallin issued a 14-day stay of execution for Warner after today's event.
"I have asked the Department of Corrections to conduct a full review of Oklahoma's execution procedures to determine what happened and why during this evening's execution of Clayton Derrell Lockett," said Fallin. "I have issued an executive order delaying the execution of Charles Frederick Warner for 14 days to allow for that review to be completed."
Both men were convicted of murder in the 1990s. Lockett was accused of a 1999 fatal shooting and Warner has been convicted of killing his girlfriend's baby daughter in 1997.
