*453 OPINION
Appellants Edward Thomas Wilson and John Steven Olausen pleaded guilty to the first degree murder of Reno undercover narcotics officer James Hoff and were sentenced to death by a three judge panel. The murder convictions, as well as convictions of related felonies (kidnapping and robbery), were affirmed by this court in Wilson v. State,
Appellants, along with two other young men, 2 carried out an elaborate, preplanned plot to kill a drug dealer for $16,000.00. The drug dealer was actually Reno police officer James Hoff, who was conducting an undercover investigation. Wilson, the apparent ringleader of the group, brought Hoff to the scene of his death where the other three were lying in wait. Hoff was stabbed a total of nine times. There was evidence that Hoff begged for his life after the first wounds were inflicted. A medical expert testified that Hoff might have lived as long as twenty minutes after the attack before dying of massive bleeding.
Hoff’s body was placed in the back of his Datsun 280Z and taken to a remote area in Verdi, where he was buried in a shallow grave. His fellow officers located the body the next day after a massive search effort.
Comparing the facts of this murder with other capital cases in Nevada, we conclude that Hoff’s murder evidences the brutality and violence present in other cases in which the death penalty was imposed.
See
Farmer v. State,
We are aware that the facts of this cáse do bear some similarity to the facts of a case in which only life imprisonment was imposed.
See
Crew v. State,
We particularly note that some flexibility must be incorporated into any scheme of proportionality review. The fact that juries have imposed a lesser penalty than death in some cases factually similar to the one under review is significant, but is not absolutely binding on the reviewing court. The unique aspects of the case under review may cause it to withstand proportionality review even in the face of points of similarity with life imprisonment cases.
See
Moore v. State,
We further conclude that nothing in the record of the proceedings below indicates that the death sentences were imposed under the influence of passion, prejudice or any arbitrary factor. Accordingly, the death sentences are affirmed. 3
Notes
NRS 177.055(2)(d) was recently amended to abolish the proportionality review requirement. This amendment became effective June 6, 1985. 1985 Stats, ch. 527 § 1, at 1597-1598. The prohibition against ex post facto laws requires that we apply the law as it existed when the crime was committed.
See
Goldsworthy v. Hannifin,
Fred Stites and David Lani also pleaded guilty to Hoff’s murder. They were sentenced to life in prison without possibility of parole by the same three judge panel which sentenced appellants to death. The panel concluded that Stites and Lani were less culpable than Wilson and Olausen because they were under Wilson’s domination and because they showed remorse immediately after the murder. The record indicates that Lani fled the scene after stabbing Hoff once in the back. Stites reportedly refused to slit Hoff’s throat after Olausen ordered him to do so, fleeing the scene after Lani. Stites also refused to participate in the hasty burial of Hoff’s body.
Appellant Wilson’s attorney requested permission during oral argument to supplement the record with additional materials relative to Wilson’s character. The motion is denied. We may not “consider matters not properly appearing in the record on appeal.” Lewis v. State,
