Albert Johnson, the "Mad Trapper" (b ?; d on the Rat River, Yukon 17 Feb 1932). Johnson (who sometimes called himself Arthur Nelson) was shot and killed by RCMP officers on the Rat River, northern Yukon Territory 17 Feb 1932. On 31 Dec 1931, an RCMP constable investigating a complaint about traplines was shot and seriously wounded by a trapper living west of Fort McPherson, NWT.
The ensuing chase lasted 48 days and covered 240 km in temperatures averaging -40°C, and at its end another policeman was badly wounded and a third, Constable Edgar Millen, had been killed. The killer, tentatively but never positively identified as Albert Johnson, was so skilled at survival that the police had to employ bush pilot "Wop" May to track him. No motive for his crimes has ever been established. A request for the exhumation of Johnson's body - to allow a fingerprint comparison - was refused by the NWT's government in June 1987.
