An Edmonton man who supplied a teenager with a semi-automatic rifle that was later used to kill two Edmonton police officers has been found guilty of manslaughter, according to reporting by the Edmonton Journal and CBC News. The case centers on the man’s role as the gun seller: he provides the weapon to a teen, and the teen subsequently uses the firearm in an attack that results in the deaths of two police officers. Both outlets report the conviction for manslaughter, describing it as a notable legal outcome in Canada. The Edmonton Journal characterizes the finding as the first of its kind in Canadian legal history, while CBC focuses on the basic finding and the connection between the gun supplier’s actions and the later killings. The sources agree that the gun was supplied to a teenager and that the weapon was later used to shoot and kill two Edmonton police officers.
