With no reprieve by the United States Supreme Court, Richard Glossip's death seemed inevitable.
That is, until Governor Mary Fallin granted Glossip 37 extra days, despite continuously saying she would deny a stay.
Fallin met with members of the media late Wednesday evening to discuss the stay.
"One of the things we do in our state is go through the execution process," Fallin said. "It's a very, very serious matter for the state that none of us take lightly."
The stay was issued after the governor received a call from the Attorney General's office.
The office had been notified by the Department of Corrections, they had received potassium acetate as part of the three drug lethal combo to be used.
The problem is proper protocol calls for potassium chloride not acetate.
"The Department of Corrections did what they should have done, which is to notify the Attorney General," Fallin said. "The Attorney General was thinking it through, called me, made me aware of it."
The use of potassium acetate is against protocol but, turns out, it's not all that different from potassium chloride.
"Basically, they do the same thing. They both cause what's called 'hyperkalemia.' It elevates doses of potassium, which will affect the rhythm of the heart," said Dani Lynch with Thrifty Pharmacy. "It'll stop your heart, regardless."
When asked if the chemical has been used in previous executions, the governor was not sure.
"That is one of the things that we're going to wait and see," Fallin said.
