The first execution of a prisoner, Kenny Smith, using nitrogen hypoxia, took place in the US state of Alabama on 25 Jan 2024. A few weeks earlier I had visited Holman prison to inspect the new equipment they planned to use, and met Kenny on death row with his lawyer Robert Grass. I gave evidence at a hearing in Montgomery a week later in an attempt to stop the execution. Kenny died, but accounts of a slow grotesque death were horrible. When I talked with him I should have explained how he could have made his death fast, peaceful and effective.
