In the wake of a botched execution , an Oklahoma court has granted a six-month stay for a man on death row . Earlier , the state 's attorney general had said his office would not object to the stay for Charles Warner . An investigation into the death of Clayton Lockett last month continues . His lethal injection was stopped because of problems in administering the drugs . Officials say he later died of an apparent heart attack . Witnesses described the man convulsing and writhing on the gurney , as well as struggling to speak , before officials blocked their view . It was the state 's first time using a new , three-drug cocktail for an execution . Warner had been scheduled to be put the death the same day as Lockett , but his execution was stayed . `` No one wants to see another prolonged , botched execution take place , so we are greatly relieved that the Court of Criminal Appeals stayed Charles Warner 's scheduled execution , as both Mr. Warner and the State requested , '' Susanna Gattoni and Seth Day , attorneys for Warner , said in a statement . `` The extreme secrecy surrounding lethal injection that led to Mr. Lockett 's agonizing death must be replaced with transparency in order to ensure that executions are legal and humane , '' they said . Attorney General Scott Pruitt 's office filed court documents Thursday that said he would not protest a 180-day stay to allow for the completion of the investigation . Warner 's execution , which had been set for May 13 , is now scheduled for November 13 .
