STATE of Washington, Respondent,
v.
Curtis Scott BUCKNER, Appellant.
Supreme Court of Washington, En Banc.
John Troberg, Colville, Curtis Buckner, Walla Walla, for Appellant.
John G. Wetle, Stevens County Prosecutor, Colville, for Respondent.
MADSEN, Justice.
We granted the State's motion for reconsideration to consider whether we should adhere to our original holdings in this case following our decisions in other cases involving admissibility of DNA evidence and the recent publication of a national report addressing statistical issues involving DNA evidence. In light of these recent developments, we conclude that our original opinion is no longer sound. Upon reconsideration, we affirm the decision of the Court of Appeals upholding Curtis S. Buckner's conviction for first degree felony murder.
The facts are recounted in our original opinion, State v. Buckner,
After reviewing the case, we decided that in order to conform to the analysis in Cauthron, statistical probability testimony had to be given in accord with the "ceiling principle" or "another statistical model proved to be accepted in the scientific community." State v. Buckner,
The original opinion in this case also disapproved testimony in terms of statistical probabilities which implies or states that defendant is uniquely identified as the person in the human population who left the forensic *668 sample. In 1993, this court accepted the proposition that an absolute identification of an individual could be made based upon DNA analysis provided that the technology exists to do so, because, except for identical twins, each individual's DNA is unique. State v. Cauthron,
Thus, we now conclude there should be no bar to an expert giving his or her expert opinion that, based upon an exceedingly small probability of a defendant's DNA profile matching that of another in a random human population, the profile is unique. As in the case of all expert testimony, the opposing side will be able to challenge the expert's opinion and present its own experts.
The 1996 report states that as the number of DNA markers increases, smaller probabilities than that introduced at trial in this case will be introduced with growing frequency. Id. Contrary to our original view in this case, we now recognize that a profile probability of 1 in 20 billion or other number greater than the earth's population may be admissible, as the state of forensic DNA analysis allows for such probabilities. Indeed, exceedingly small probabilities have been introduced in recent cases. E.g., Smith v. State,
The two bases for our disagreement with the Court of Appeals opinion in this case are no longer sound. The product rule may be used to calculate profile frequencies, and there is nothing per se wrong with introducing a probability estimate of 1 in 19.25 billion or an expert's opinion that a profile is unique.
Accordingly, we now affirm the Court of Appeals decision upholding Buckner's conviction for first degree felony murder and remanding this case for resentencing.
DURHAM, C.J., and DOLLIVER, SMITH, GUY, JOHNSON, ALEXANDER, TALMADGE and SANDERS, JJ., concur.
