A former employee of a sawmill shot four co-workers, two of them fatally. The attack began in the parking lot and then moved into the mill’s offices. The RCMP arrested the 47-year-old worker, who they believe acted alone, and seized a shotgun. The suspect, Kevin Addison, was charged with two counts of first-degree murder and two counts of attempted murder. The sawmill declined to reveal when he left the company or under what circumstances.
