An Edmonton police officer will face no sanctions for shooting a man armed with a metal rod 16 months ago, an investigation by the Alberta Serious Incident Response Team has concluded.

Kinling Robin Fire, 39, was shot and killed just after midnight on Mar. 30, 2011 behind a west-end apartment building at 155th Street and 100th Avenue.

Police were called to locate a man believed to be suicidal.

They found Fire in his car and followed him to an alley, Clif Purvis, ASIRT executive director, said in a news release.

The man left the vehicle carrying what was later determined to be a metal rod.

Officers demanded the man drop his weapon, but he continued to advance towards officers in a threatening manner.

He was shot twice and killed.

A family member told CBC News Fire was distraught after arguing with his ex-girlfriend over their son.

The ASIRT investigation found the officer, Const. Brendan Power, was justified in shooting Fire.

The investigation has been reviewed by the Calgary Chief Crown Prosecutor and the Federation of Saskatchewan Indian Nations Special Investigations Unit.

Edmonton Police Chief Rod Knecht said Tuesday that he was satisfied with the ASIRT decision.

"The fact that no charges will be laid affirms the appropriateness of Const. Power’s actions, and to the skill and training of all the officers involved," Knecht said.

"The outcome of the ASIRT investigation determined that our members made every attempt to properly subdue Mr. Fire in the moments leading up to this terrible event."
