(a) Where the sentence of death is pronounced against a convict, the sentence shall be executed at any hour on the day set for the execution, not less than 30 nor more than 100 days from the date of sentence, as the court may adjudge, by lethal injection unless the convict elects execution by electrocution as provided by law. If electrocution is held unconstitutional, the method of execution shall be lethal injection.
(b) Executions shall take place at the William C. Holman unit of the prison system at Atmore in a room arranged for that purpose. It shall be the duty of the Department of Corrections of this state to provide the necessary room and appliances to carry out the execution.
(c) The warden of the William C. Holman unit of the prison system at Atmore or, in case of his or her death, disability, or absence, his or her deputy, shall be the executioner. In the case of execution by lethal injection, the warden, or in the case of his or her death, disability, or absence, his or her deputy, may designate an employee of the unit to administer the lethal injection. In the event of the death or disability or absence of both the warden and deputy, the executioner shall be that person appointed by the Commissioner of the Department of Corrections.
