The accused, a former army reservist, shot and killed a prowler who was breaking into his truck.
At trial, the accused claimed self-defence, arguing his military training led him to proactively confront the threat and that he believed the prowler was reaching for a gun.
The jury acquitted the accused of second-degree murder.
The Crown appealed, arguing the trial judge erred in his instructions to the jury regarding self-defence under s. 34 of the Criminal Code.
The Court of Appeal allowed the appeal and ordered a new trial, finding the trial judge failed to instruct the jury to consider the accused's conduct leading up to the shooting when assessing the reasonableness of his actions.
