Alabama Drops Lethal Injection for Alan Miller, But May Attempt Execution With Nitrogen Gas

Alabama offi­cials have agreed not to make a sec­ond attempt to exe­cute Alan Miller by lethal injec­tion after the state had to call off his September 22, 2022 exe­cu­tion because of the fail­ure to estab­lish an IV line. If the state seeks to exe­cute Miller in the future, it will use nitro­gen hypox­ia, a method that has nev­er been used for an exe­cu­tion.
