As part of the investigation, RCMP issued a request for information from anyone who heard gunshots, who had security or dashcam video or who saw anything they thought was suspicious.
Following the years-long investigation, police obtained an arrest warrant for their suspect, a Mackenzie County resident, on June 25.
Amadeus Laforce was arrested July 3 and charged with second-degree murder. He was remanded into custody and is scheduled to appear in Grande Prairie court on Monday.
