Wainwright was 50 years old, a long time resident of Benito, with a wife and four grown children. Shaw was from the Sifton, Manitoba area and engaged to be married.

The two were transferring three men: Joseph Posnikoff; Peter Woiken; and John Kalmakoff, from Manitoba back to Pelly, Saskatchewan where they were wanted for questioning in a robbery. Just outside Pelly, one suspect overpowered Wainright with a knife, took his gun and shot the two officers to death.

The three fled in the car until they meet an RCMP roadblock outside in Canmore, Alberta. In the ensuing shoot-out another suspect is killed along with two more R.C.M.P. officers. The remaining man fled into the bush but a manhunt finds him and he is killed. In all, seven lives were lost.
