Tennessee Supreme Court allows execution of inmate with heart device, as legal and ethical issues are considered.

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.

A Tennessee hospital says it never agreed to a request by state officials who face a court order to turn off a death row inmate’s heart-regulating implant before receiving a lethal injection next week.
