The Tennessee prison chief who oversaw the botched execution of murderer Christa Pike has stepped down from the position.

Tennessee Department of Correction Commissioner Frank Strada offered his resignation to Republican Gov. Bill Lee on Oct. 3, according to a report from The Tennessean.

Strada maintained that the department carried out its responsibilities “in accordance with established protocol,” the report stated.

“Even so, stepping aside is in the best interest of Tennesseans as the independent review moves forward,” Stada said. “I believe this review is entirely appropriate and necessary, and I look forward to doing everything I can to help determine exactly what occurred.”
