Tennessee Prisons Chief Resigns After Botched Christa Pike Execution

The head of Tennessee's prison system has resigned following the botched execution of death row inmate Christa Pike, who survived two injections of the execution drug and was later taken to hospital.

Tennessee Governor Bill Lee announced on Saturday that Department of Correction Commissioner Frank Strada would leave his position later this month, as an independent review examines what went wrong during Pike's execution.

Lee said Strada had served the state with integrity and had agreed to step down in what he described as the best interests of Tennesseans.

"Commissioner Strada has served with integrity, and I appreciate his willingness to put the interests of Tennesseans first during this difficult moment," Lee said.

A successor has not yet been announced.

Strada has led Tennessee's Department of Correction for about three years. Before taking the position, he was a senior official in Arizona's corrections system, where several executions conducted during his tenure encountered complications.

In announcing his resignation, Strada said he supported the independent investigation and would cooperate with efforts to establish what happened during Pike's execution.

"I believe this review is entirely appropriate and necessary, and I look forward to doing everything I can to help determine exactly what occurred," he said.

Pike was scheduled to be executed on Wednesday using pentobarbital, a drug Tennessee employs for lethal injections. The procedure failed, however, and Pike survived two attempts to administer the drug before being transported from prison to hospital.

Her lawyers later said she was unconscious and had been intubated and placed on a ventilator while medical personnel worked to remove the drug from her system.

In a court filing, Pike's legal team alleged that problems with the intravenous lines meant the pentobarbital did not properly enter her bloodstream.

They argued that members of the execution team apparently failed to recognise that the IV lines had been incorrectly positioned or that Pike's veins had failed, potentially allowing some or all of the drug to enter surrounding tissue rather than her bloodstream.

Pike's lawyers said Strada's resignation was justified but argued that it did not address the broader concerns raised by the failed execution.

They described the incident as evidence of what they believe are systemic problems within Tennessee's death-penalty system and said they hoped the governor's independent review would examine the system as a whole.

Pike was sentenced to death for the torture and murder of another young woman in 1995. She was 18 at the time of the crime and became one of the youngest women in the United States to be sentenced to death.

Following the failed execution, Lee suspended all executions in Tennessee for the remainder of the year while the state investigates the circumstances surrounding Pike's case.

The independent review is expected to examine the procedures followed by the execution team, including the administration of the lethal injection and the medical response after the procedure failed.
