Alabama executes man using nitrogen gas in third U.S. execution of its kind

Alabama executed Carey Dale Grayson on Thursday, marking the third use of nitrogen gas for an execution in the U.S. Grayson, 50, was convicted of the 1994 murder of hitchhiker Vickie Deblieux. The execution took place at William C. Holman Correctional Facility after the U.S. Supreme Court denied Grayson's request for a stay. His attorneys raised concerns about the new method, claiming it could cause suffering. Nitrogen gas replaces breathable air, leading to death by lack of oxygen. Critics argue the method requires further examination due to issues in previous executions, where inmates showed signs of distress.
