Alabama Executes Third Inmate with Nitrogen Gas in Controversial Case

Alabama executed Carey Grayson using nitrogen gas, marking the third such execution in the state this year. Grayson was convicted of the 1994 murder of Vickie Lynn Deblieux. The US Supreme Court denied a stay of execution, despite arguments that nitrogen asphyxiation is cruel and unusual punishment. Alabama is the only US state using this controversial method, which has been criticized by human rights experts and the UN. Grayson's execution has reignited debates over the death penalty and humane methods of execution.
