The appellant was convicted of first degree murder in the death of Diane Werendowicz, who was sexually assaulted and strangled in 1981.
The appellant's DNA matched semen found on the victim.
The case proceeded through four trials: the first resulted in conviction (later overturned on appeal), the second and third ended in hung juries, and the fourth resulted in conviction.
The Crown's key evidence included a 911 call traced to a phone booth near the appellant's workplace, voice identification evidence, and DNA evidence.
The appellant challenged the trial judge's jury instructions on the call tracing evidence, voice identification evidence, and other matters.
The Court of Appeal dismissed the appeal, finding the jury instructions adequate and fair.
