Alabama has executed convicted murderer Kenneth Eugene Smith with nitrogen gas, the first time the method of capital punishment has been used in the US. Smith, 58, lost two final appeals to the Supreme Court and one to a federal appeals court, arguing the execution was a cruel and unusual punishment. In 2022, Alabama tried and failed to execute Smith by lethal injection. He was convicted in 1989 of murdering a preacher’s wife, Elizabeth Sennett, in a killing-for-hire.
