A man convicted of killing his estranged wife has died after spending more than four decades on Florida’s death row.

An octogenarian death row has died, according to Florida court records, making him at least the seventh death row inmate to die while waiting for their sentence to be carried out.

A Tennessee judge ruled Tuesday that the state can deactivate a death row inmate's implanted heart-regulating device at a hospital on the morning of his execution, rather than bringing a doctor or technician into the execution chamber.
