Seven months after a 49-year-old man was fatally shot by RCMP officers in Onoway, the Alberta Serious Incident Response Team has found the officers’ actions were justified.

On January 11th, Stony Plain RCMP members were called to a domestic disturbance at an apartment building in Onoway.

RCMP said two officers arrived at the apartment building to find a male, later identified by neighbours as 49-year-old Darby Mahon, armed with a knife.

ASIRT officials say police demanded that the man drop the weapon. They say he didn’t obey, and instead approached the officers with the knife.

ASIRT says despite asking the man more than once to drop the weapon, he continued to approach and that’s when the officers fired their weapons.

Police say paramedics attended the scene, but the man was pronounced dead on scene.

A witness at the time told CTV News the man was angry with another resident of the apartment before police were called. The witness said he'd tried to intervene when Mahon started trying to bust down the door to a basement apartment.

ASIRT says the results of the investigation found both police officers were acting in self-defense when they fired their guns.

“The executive director of ASIRT has determined that they were acting lawfully and were justified in their actions,” states a news release from ASIRT.
