The appellant was convicted of second-degree murder for the shooting deaths of his parents.
At trial, the Crown relied on circumstantial evidence, including the appellant's exclusive insider opportunity and physical evidence, to prove he committed the murders and fabricated a story about an intruder.
On appeal, the appellant argued the trial judge erred in his jury instructions regarding the defence theory, motive, post-offence conduct, and the burden of proof.
The appellant also challenged the trial judge's rulings on the admissibility of expert evidence and sought to introduce fresh evidence.
The Court of Appeal dismissed the appeal, finding no reversible errors in the jury instructions or evidentiary rulings.
The court held that the fresh evidence did not meet the due diligence criterion and would not have affected the verdict.
Furthermore, the court applied the curative proviso under s. 686(1)(b)(iii) of the Criminal Code, concluding that the evidence of guilt was so overwhelming that no substantial wrong or miscarriage of justice occurred.
