(e) If the defendant is found guilty of a capital offense or offenses with which he or she is charged and the defendant establishes to the court by a preponderance of the evidence that he or she was under the age of 18 years at the time of the capital offense or offenses, the sentence shall be either life without the possibility of parole or, in the alternative, life, and the sentence shall be determined by the procedures set forth in the Alabama Rules of Criminal Procedure for judicially imposing sentences within the range set by statute without a jury, rather than as provided in Sections
13A-5-45 to
13A-5-53, inclusive. The judge shall consider all relevant mitigating circumstances.
If the defendant is sentenced to life on a capital offense, the defendant must serve a minimum of 30 years, day for day, prior to first consideration of parole.
