Convicted triple-murderer Byron Black might elude his scheduled execution on Tuesday morning due to a recently claimed intellectual disability and dementia.

Attorneys for Byron Black, a 66-year-old man on Tennessee's death row, have filed a motion for a stay of his execution due to the potential for his implanted defibrillator to trigger a prolonged and gruesome death.

Tennessee can execute Byron Black on Aug. 5 without having to first deactivate his heart device, the Tennessee Supreme Court has ruled.
