Alabama's attorney general announced that the state will proceed with the execution of Alan Miller using nitrogen gas in September, following a confidential settlement that ends his legal challenges against the method. Miller, convicted of killing three men, had filed a lawsuit citing concerns about the execution process based on witness accounts of Kenneth Smith's nitrogen gas execution in January 2024. Despite his suggestions for changes to the protocol, including the use of medical-grade nitrogen and supervision by trained professionals, the state has not confirmed if these modifications will be implemented. Attorney General Steve Marshall characterized the settlement as a victory for the nitrogen gas execution method, asserting its reliability and humane nature. Miller's attorney stated that the agreement protects his constitutional rights against cruel and unusual punishment. The execution is scheduled for September 26.
