The execution of Clayton Lockett was scheduled to start at PM, with a prison official standing by a telephone to receive the call that it was done. But as the clock continually moved closer to 7, that call never came.
It was shortly after PM when the Director of the Department of Corrections announced that something had gone wrong roughly 7 minutes into the procedure.
"There was some concern at that time that the drugs were not having the effect so the doctor observed the line and determined that the line had blown," said Robert Patton.
Unsure of just how much of the lethal cocktail the inmate had received, the director brought the proceedings to a halt.
"It was my decision at that time to stop the execution," he said.
But then, 43 minutes after the first injection of 6:23, Clayton Lockett would die anyway.
"At approx. 7:06 hours, inmate suffered what appears to be a massive heart attack and passed away," he said.
"I really don't, it's just horrible," said Father Bryan Brooks.
He was holding vigil at the front gates, and was stunned at the outcome.
"Its rather ironic because the whole issue about the legal battle over the drugs themselves and whether or not they could be used in such an execution, that it would cause a quick death, that would be compatible with, that it would not be a form of cruel and unusual punishment, so then for his death to occur under these circumstances is certainly interesting to say the least," he said.
Governor Fallin has asked the Department of Corrections to conduct a full review of Oklahoma's execution procedures to determine what happened.
