Facts of the Crime:

On December 7, 1992, Miles and two 16-year-old companions planned a carjacking and discussed killing someone. At 1:30 p.m. that day, Miles and his two companions waited for a car to stop near the area of 24th Street and Columbus Avenue in Tucson.

When the 40-year-old victim approached in her vehicle and stopped, one of the two companions asked her for a "light" for a cigarette. As she reached for the lighter, the companion pointed a .45 caliber handgun at her head and forced her to move over. Miles and the two companions took control of the car, kept the gun pointed at her, and drove her to a desert area, where she was shot once in the chest. She died from this gunshot wound, which lacerated her heart and her left lung.

Miles was sentenced to death on July 6, 1993.
