An inmate executed by the state of Tennessee reportedly cried out in pain shortly after the lethal injection began, with witnesses claiming he was "hurting so bad" despite an implanted defibrillator remaining active. Byron Black's death has sparked controversy, as he was put to death amid uncertainty over whether the device would shock his heart as the lethal chemicals took effect.

Prison officials confirmed Black died at 10:43 a.m., approximately 10 minutes after the execution commenced. Asked for any last words, he replied, "No sir." As the process began, Black was observed looking around the room, lifting his head off the gurney multiple times, sighing and breathing heavily. All seven media witnesses present agreed he appeared to be in discomfort. A spiritual advisor prayed and sang over Black throughout the execution, at one point touching his face.
