Governor Bill Lee said Strada would leave his position later in October, the first major staff shake-up since Wednesday's failed execution. Some of Lee's fellow Republicans and other elected officials had been urging a change in leadership, the governor noted.
Strada said in a statement that resigning was "in the best interest of Tennesseans" while an independent review determines what occurred. "I believe this review is entirely appropriate and necessary," he said. Strada also said he believes the state "carried out its responsibilities in accordance with the established protocol."
Lee has appointed former US attorney Ed Stanton to lead the review. Stanton previously conducted a review in 2022 after Lee called off a different execution, finding that Tennessee had not complied with its own lethal injection process.
The failed execution on Wednesday saw Pike, 50, receive two doses of pentobarbital intravenously but remain alive. Her lawyers said she could be heard "crying, whimpering, and breathing loudly throughout the procedure." She was taken to a Nashville hospital, where she remained unconscious and on a ventilator as of Thursday night. Hospital staff were working to clear the drugs from her system, her lawyers said in an emergency motion seeking to preserve evidence. The lawyers said problems with the IV lines likely caused the pentobarbital to flow into her body instead of her bloodstream, leaving her arms "swollen, burned and blistered."
It was the second time since May that Tennessee has been unable to execute a prisoner who was seemingly moments away from death. Lee has halted all executions in the state this year.
Pike was sentenced to death in 1996 for the murder of a classmate, Colleen Slemmer, when she was 18. She became one of the youngest women on death row. Lee rejected a clemency petition that cited her history of severe neglect, sexual abuse and untreated mental illness. The state's Department of Correction has defended the method, saying "the protocol does not allow for additional procedures beyond what was carried out."
