The Tennessee Department of Correction (TDOC) has finalized a significant revision of its lethal injection protocol, opting to use the single drug pentobarbital for executions moving forward. This decision follows a hiatus on executions that began in May 2022, after Governor Bill Lee called for an independent review of the procedures. The move to revise the state’s method of execution also came with new leadership under Commissioner Frank Strada, who had been tasked with developing an updated protocol since January 2023.
