Tennessee readies for execution of man with working implanted defibrillator

Tennessee is gearing up for an execution on Tuesday that experts say would likely mark the first time a man has been put to death with a working defibrillator in his chest. Gov. Bill Lee declined Monday to grant a reprieve, clearing the way for Byron Black’s execution after a legal battle and ongoing uncertainty about whether the implantable cardioverter-defibrillator will shock his heart when the lethal drug takes effect. The nonprofit Death Penalty Information Center said it’s unaware of any other cases in which a person on death row made similar claims to Black's about defibrillators or pacemakers.
