In a notable development in capital punishment practices, Alabama has executed Alan Eugene Miller using nitrogen gas, marking the state's second execution utilizing this method. Miller, who was convicted of killing three individuals in 1999, became the second inmate in the United States to be executed via nitrogen gas. This execution follows increased scrutiny and controversy surrounding the nitrogen gas method, which critics describe as brutal and secretive. The execution took place on a Thursday, with Alabama's Department of Corrections affirming the use of nitrogen hypoxia, despite concerns over its humaneness and the implications of its use in the death penalty.
