Tennessee Executes Inmate Without Deactivating Implantable Defibrillator

Black’s death has propelled this year’s U.S. execution total to a five-year high

A 60-year-old Oklahoma man who stabbed a prison cafeteria worker to death in 1998 is scheduled to receive a lethal injection Thursday, Oct. 28, 2021 in the state's first attempt to administer the death penalty since a series of flawed executions more than six years ago. The state was moving forward with John Marion Grant's lethal injection after the U.S. Supreme Court, in a 5-3 decision, lifted stays of execution that were put in place on Wednesday for Grant and another death row inmate, Julius Jones, by the 10th U.S. Circuit Court of Appeals.

Overview

  • Byron Black was executed by lethal injection at 10:43 a.m. on August 5 in Tennessee with his implantable cardioverter defibrillator left active.
  • The U.S. Supreme Court declined his final appeal on August 4 and Governor Bill Lee refused clemency, ending his legal and executive options.
  • A mid-July trial court order to deactivate the device was overturned days later by the Tennessee Supreme Court.
  • Black’s defense argued that his dementia, brain damage and heart failure could worsen pain if the device delivered shocks during the procedure.
  • The case has underscored ethical objections from health care professionals who view execution involvement as a breach of medical ethics.
