The nitrogen hypoxia execution of Alan Eugene Miller is scheduled to take place between midnight on September 26 and midnight on September 27.

The state previously attempted to execute Miller by lethal injection, but the execution was called off after officials were unable to find a vein. Death row inmates have been known to dehydrate themselves by not eating or drinking leading up to the execution to botch the process.

Miller, a delivery truck driver, killed three co-workers at two businesses in Shelby County on Aug. 5, 1999. Christopher Scott Yancy and Lee Holdbrooks were killed at Ferguson Enterprises, and Terry Lee Jarvis was killed at Post Airgas.

During the trial, it was revealed that Miller believed the men had been spreading rumors about him.

Miller will be the second person to be put to death by nitrogen hypoxia. The process replaces oxygen with nitrogen, causing the inmate to die. The first was Kenneth Eugene Smith, who was executed in January.
