Mayerthorpe tragedy

The Mayerthorpe tragedy occurred on March 3, 2005, on the property of James Roszko, approximately 11 km (6.8 mi) north of Rochfort Bridge near the Town of Mayerthorpe in the Canadian province of Alberta. With a Heckler & Koch 91, Roszko shot and killed Royal Canadian Mounted Police Constables Peter Schiemann, Anthony Gordon, Lionide Johnston, and Brock Myrol as the officers were executing a property seizure on the farm. This was the worst one-day loss of life for the RCMP in 100 years.
