 The Arizona Supreme Court affirmed the conviction and sentence.With respect to the finding that the murder was committed in an especially heinous, cruel, or depraved manner, the court observed that under its prior case law, the murder was cruel in light of the evidence that Powell had some uncertainty as to his ultimate fate, and the murder was depraved in light of the evidence that Walton had relished the killing.Reviewing the death sentence independently, it found that the death sentence was appropriate on these facts.
