Surly and unfriendly, Johnson built a cabin in the summer of 1931 at prime trapping grounds along the Rat River in the Northwest Territories—but he never got a licence to trap.

When trapping season started, members of the Loucheux First Nation found someone interfering with their traps—and the only new person on the scene was Johnson. They complained to Millen at Fort McPherson, south of Inuvik.

Millen sent out two investigators, who trekked a week to Johnson’s cabin. Met with surly resistance, the constables went to Aklavik for reinforcements and a search warrant. When the expanded party of four reached the cabin again on Dec. 31, 1931, Const. Alfred King was severely wounded.

The authorities returned in force in January, with four constables, Inspector Alexander Eames, three trappers, 42 dogs and about 10 kilograms of dynamite. Johnson would not surrender, despite a 15-hour siege during which the cabin was blown up. The posse was forced to return to base to restock.

When they caught up with him on Jan. 30, he killed Millen and fled over the 1,200-metre Richardson Mountains into the Yukon.

Hundreds of people became involved in tracking him. For the first time, the RCMP used a plane to help get their man, enlisting legendary bush pilot Wilfred (Wop) May, who directed them to the Eagle River. It took two weeks for a crack team to catch up with him.

Johnson, prepared for a gunfight, was armed with three rifles and plenty of ammunition.

In the ensuing shootout on Feb. 17, Johnson was killed and Staff Sergeant H.F. Hersey, of the Royal Canadian Corps of Signals, was injured.

Mystery still surrounds the case. Who was Johnson? Why was he trapping in the wilderness when he had in his possession a fortune worth about $60,000 in today’s dollars? Was Johnson even his real name? No one knows.
