Louisiana's oldest death row inmate dies less than month before execution date

A terminally ill man who spent over 30 years on death row in Louisiana for the killing of his stepson died days after a March date was scheduled for his execution by nitrogen gas.

Christopher Sepulvado, 81, died Saturday at the Louisiana State Penitentiary in Angola, Louisiana, "from natural causes as a result of complications arising from his pre-existing medical conditions," according to the Louisiana Department of Public Safety and Corrections.

He was the oldest of the 57 inmates on death row as the state weighed resuming executions after a 15-year pause, CBS affiliate WWL-TV reported.
