An Edmonton man was found guilty of manslaughter this month for selling the rifle used to kill two police officers [1], [2].
The verdict establishes a legal precedent for the responsibility of firearm sellers when weapons are used in violent crimes. It highlights the critical link between illegal gun trafficking and the deaths of law enforcement personnel.
Dennis Okeymow sold a semi-automatic rifle to Roman Shewchuk, who was 16 [1], [2]. Shewchuk used that weapon to kill Constable Travis Jordan and Constable Brett Ryan in 2023 [1], [2].
The court delivered the manslaughter verdict in May 2026 [2], [4]. The decision followed a legal analysis of whether Okeymow could have reasonably foreseen that the rifle would be used to commit a violent crime [1], [3].
Under the legal test for manslaughter, the court concluded that Okeymow's actions in supplying the firearm contributed to the deaths of the two officers [1], [3]. The case centered on the foreseeability of harm associated with the sale of such a high-powered weapon to a minor.
The incident sparked significant grief and outcry within the Edmonton community and the law enforcement sector. The deaths of the two officers [1] marked one of the most violent encounters with police in the region's recent history.
“Dennis Okeymow was found guilty of manslaughter for supplying a semi‑automatic rifle.”
This conviction underscores a judicial shift toward holding firearm suppliers accountable for the eventual use of the weapons they sell. By applying the manslaughter test to a seller rather than just the shooter, the court is signaling that the act of providing a lethal weapon to a high-risk individual—such as a minor—carries severe criminal liability if that weapon is used in a killing.
