The head of Tennessee's prison system is resigning in the wake of the failed execution of Christa Pike.
Tennessee Governor Bill Lee announced that Frank Strada, commissioner of the Department of Correction, will step down this month, in the first major staff shake-up since Pike's stunning failed execution left her unconscious and on a ventilator in hospital.
It was the second time since May that Tennessee has not been able to execute a prisoner.
Independent review into failure
Mr Strada said in a statement that resigning was "in the best interest of Tennesseans", while an independent review determines what happened on Wednesday when the state failed to execute Pike despite administering two doses of a lethal drug, pentobarbital.
Pike, now 50, was 18 when she and her boyfriend tortured and killed a classmate, Colleen Slemmer, in a jealous rage in 1995.
She became one of the youngest women to be sent to death row.
She had been scheduled to become the first woman executed in Tennessee in more than two centuries, and the only person in the modern era of US capital punishment to be executed in that state for a crime committed by a teenager.
Pike's then-17-year-old boyfriend was tried as an adult and convicted of murder, but received a life sentence with eligibility for parole.
A third schoolmate who was 18 at the time and acted as a lookout testified for the prosecution and received probation.
Mr Lee this week rejected a clemency petition seeking to commute Pike's death penalty to a life prison term without the possibility of parole.
The petition argued for leniency, in part, on the basis of her childhood history of severe neglect, sexual abuse that included two rapes, and untreated mental illness.
Strada defends execution protocol
Pike's lawyers said they believed problems with the intravenous lines caused the pentobarbital to flow into her body instead of her bloodstream.
Hospital staff were working to save Pike's life and clear the pentobarbital from her system, her lawyers said in an emergency motion, which seeks a court order for Tennessee's Department of Correction to preserve evidence from the botched execution, Pike's lawyers said.
Pike remained in critical condition, intubated and hooked to a mechanical ventilator to breathe, her lawyers said, after two doses of pentobarbital were administered to her intravenously at the Riverbend Maximum Security Institution in Nashville.
The bungled attempt to establish intravenous lines also left both her arms "swollen, burned and blistered", the apparent result of the pentobarbital, a highly alkaline and caustic substance, seeping into the tissues under her skin, the court filing said.
Mr Lee has ordered an independent review and halted any new executions.
Mr Strada said he believed the state "carried out its responsibilities in accordance with the established protocol".
Pike's legal team welcomed Mr Strada's departure but said "it does nothing to help Christa now".
"What happened to her reflects a systemic failure that goes far beyond any one person," her legal team said.
"We hope the governor's call for a full, independent review will expose the profound problems within Tennessee's entire death penalty system."
Second failed execution since May
In May, Tennessee stopped the execution of Tony Carruthers after staff placed an IV into his right arm but couldn't get a secondary IV line.
The governor ordered officials to wait at least a year before trying to execute him again.
Mr Strada took over the Correction Department in January 2023.
In late 2024, he announced that Tennessee was changing its lethal injection protocol and would use only pentobarbital.
Four people have been executed in Tennessee since 2025, according to the Correction Department.
