“ The trial judge overrode the jury's recommendation and sentenced respondent to death. He unequivocally stated that his decision to impose the death sentence was based on the collateral crimes evidence that had been received for the limited purpose of proving respondent's identity at the guilt phase of the trial. ”

“ And, with respect to sentence, the state court's reliance on Johnson for the proposition that the death sentence could not stand when it was based on evidence that had been rendered unreliable was entirely correct. When a state supreme court, in compliance with our mandate, has applied an intervening decision in a permissible fashion, we should respect its decision even if we might detect a slight flaw in its opinion. ”

“ Our review of the record reveals that the state introduced no evidence at the sentencing phase beyond that established at the guilt phase. There was no evidence of two of the three aggravating factors other than the collateral crimes evidence. The United States Supreme Court held in Johnson that the eighth amendment requires a stringent review of death sentences based in part on improper aggravating circumstances. ”

“ In this case, the judge found the aggravating factors of witness elimination and cold, calculated and premeditated murder based predominantly, if not exclusively, on the Williams rule evidence presented during the guilt phase of the trial. ”
