Oklahoma Moves Forward with Execution by Nitrogen Gas Chamber

Oklahoma will execute prisoners using an experimental method never before attempted anywhere in the world: nitrogen hypoxia.
Mike Hunter, the state’s attorney general, and Joe M. Allbaugh, the director of the department of corrections, announced Oklahoma will asphyxiate prisoners by locking them in a chamber that will fill with a physiologically inert gas, such as nitrogen. Such gases are not toxic but instead deplete blood oxygen levels.
