Currently, only New Hampshire has a law specifying hanging as an available secondary method of execution, now only applicable to one person, who was sentenced to capital punishment by the state prior to its repeal in 2019.
The hanging of Billy Bailey is likely to be the final hanging in the United States, considering that all three of the states that maintained hanging as a secondary method of execution alongside lethal injection after the 1976 restoration of the death penalty have now abolished executions. Delaware's Supreme Court declared the death penalty to be in violation of their state constitution in 2016,[21] Washington abolished executions in 2018,[22] and New Hampshire abolished executions in 2019.[23] However, the last person on death row in the three states is Michael K. Addison in New Hampshire, convicted in 2008 of the 2006 murder of Michael Briggs, an on-duty police officer. Should the state carry out Addison's execution, the method could be hanging if lethal injection was found unconstitutional or inefficient, or if he chooses to be executed by hanging.
