OKLAHOMA CITY (AP) — A special grand jury looking into Oklahoma's execution procedures said Thursday a top lawyer for Gov. Mary Fallin encouraged the use of the wrong lethal injection drug in an execution that was later called off. The grand jury did not issue any indictments.
After conducting 112 executions since 1976, Oklahoma imposed a moratorium in October 2015 following three consecutive flawed executions or attempted executions. In two of those cases, a company whose identity is kept secret under state law sent the wrong drug to prison officials to be used during the three-drug lethal injection process — and the wrong drug was actually used in one of those executions.
Here is a look at those and other issues surrounding executions in Oklahoma:
— Aug. 11, 1995: Robert Brecheen attempted suicide ahead of his scheduled execution, using sedatives and anti-anxiety pills he had hoarded in his cell. He was rushed to a hospital, had his stomach pumped and was returned to the death chamber, where he was executed hours later.
— Nov. 6, 2012: Garry Allen is executed despite the state parole board's clemency recommendation and arguments that he was insane. He had been shot in the head during his arrest and spent his final moments rambling about the presidential election. Allen, who was executed on Election Day, appeared startled when a prison official announced the start of his execution. Among his last words were, "What? Huh?"
— Jan. 9, 2014: Michael Lee Wilson was given pentobarbital, vecuronium bromide and potassium chloride during his lethal injection, and said "I feel my whole body burning" as he died.
— April 29, 2014: Clayton Lockett writhed and groaned on the gurney as Oklahoma used the surgical sedative midazolam for the first time during an execution. State prisons director Robert Patton halted the execution process, but Lockett died 43 minutes later. His death was ruled a heart attack. The state later says an improperly placed intravenous line — not the new drug mix — caused problems with Lockett's execution. A second execution set that night, for Charles Warner, was postponed.
— June 25, 2014: Inmates sue Oklahoma, alleging the state unconstitutionally allows an "ever-changing array of untried drugs" during executions.
— Dec. 22, 2014: A federal judge declares Oklahoma's lethal injection protocol constitutional. The U.S. Supreme Court says later it will consider whether Oklahoma can use midazolam during executions, but it doesn't disrupt Warner's rescheduled execution.
— Jan. 15, 2015: Oklahoma executes Warner for the 1997 killing of his roommate's infant daughter. "My body is on fire," he said after receiving midazolam, though he showed no other signs of distress.
— June 29, 2015: A sharply divided U.S. Supreme Court upholds Oklahoma's use of midazolam during executions.
— Sept. 30, 2015: Prison officials prepare to execute Richard Glossip, but Oklahoma Gov. Mary Fallin issues a 37-day stay, saying the state Department of Corrections received the wrong drug, potassium acetate, rather than the potassium chloride listed in the state's execution protocol.
— Oct. 2, 2015: All executions are put on indefinite hold in the state by the Oklahoma Court of Criminal Appeals at the request of Attorney General Scott Pruitt, who calls for an inquiry into the state's execution procedures.
— Oct. 8, 2015: The Oklahoman newspaper reports that the state used potassium acetate during Warner's execution in January, rather than potassium chloride. Fallin says she agrees all executions should be delayed after an autopsy report revealed the wrong drug was used to stop the inmate's heart.
— Oct. 29, 2015: Anita Trammell, who as warden of the Oklahoma State Penitentiary presided over the three botched execution attempts, retires after appearing before Pruitt's grand jury. The prison system said her departure is not related to the probe.
— Dec. 4, 2015: Patton, whom Fallin backed to lead the Oklahoma prison system and who oversaw each of the three botched execution attempts, resigns weeks after appearing before Pruitt's grand jury. The prison system said his departure is not related to the probe.
— Jan. 7, 2016 — Fallin names former Federal Emergency Management Director Joe Allbaugh as interim director of the Department of Corrections.
— Feb. 11, 2016: Fallin's general counsel, Steve Mullins, resigns after appearing before the grand jury. Fallin's office would not say whether his departure is related to the probe.
— May 19, 2016: An Oklahoma grand jury investigating the state's execution procedures issues its 106-page report with no indictments. It does say Mullins encouraged the use of the wrong lethal injection drug in an execution that was later called off.
