The appellant was convicted of two counts of first-degree murder after the elderly victims were stabbed in their sleep.
The Crown relied on circumstantial evidence, including the appellant's motive, opportunity, blood on his track pants, and a confession to an undercover officer.
The trial judge admitted expert evidence from a police officer regarding crime scene reconstruction and criminal profiling.
On appeal, the appellant challenged the admission of the expert evidence, demeanour evidence, and the conduct of Crown counsel.
The Court of Appeal held that while the criminal profiling evidence was inadmissible, the crime scene reconstruction evidence was properly admitted.
The court applied the curative proviso to the profiling evidence, finding the case against the appellant overwhelming, and dismissed the appeal.
