Albert Johnson ( – February 17, 1932), also known as the Mad Trapper of Rat River, was a fugitive whose actions stemming from a trapping dispute eventually sparked a huge manhunt in the Northwest Territories and Yukon in Northern Canada. The event became a media circus as Johnson eluded the Royal Canadian Mounted Police (RCMP) team sent to take him into custody, which ended after a pursuit lasting more than a month and a shootout in which Johnson was fatally wounded on the Eagle River, Yukon. Albert Johnson is suspected to have been a pseudonym and his true identity remains unknown.

Attack on police

Albert Johnson arrived in Fort McPherson after coming down the Peel River on July 9, 1931. He was questioned by RCMP constable Edgar Millen, but provided little information. Millen thought he had a Scandinavian accent, generally kept himself clean-shaven, and seemed to have plenty of money for supplies. After venturing the waterways in an indigenous-built raft to the Mackenzie River delta, he built a small cabin on the banks of the Rat River. Johnson had not acquired a trapping licence, which was considered odd for someone living in the bush. At that time many northern native traditional trapping areas were being invaded by outsiders fleeing the Great Depression and some complaints may have been intended to remove him.

In December, indigenous trappers complained to the local RCMP detachment in Aklavik that 'Johnson' was tampering with their traps, tripping them and hanging them on the trees. A post incident investigation by the RCMP "found an entirely different story. Evidently, Johnson had roughly told them to take off and had even pointed a gun at them, when they came-a-visiting at Johnson's cabin".

On December 26, Constable Alfred King and Special Constable Joe Bernard, each of whom had a considerable northern experience, trekked the to Johnson's cabin to ask him about the allegations. Seeing smoke coming from the chimney, they approached the hut to talk. Johnson refused to talk to them, however, seeming not even to notice them. King looked into the cabin window, at which point Johnson placed a sack across it. The two constables eventually decided to return to Aklavik and get a search warrant.

King and Bernard returned five days later with two other men. Johnson again refused to talk and eventually King decided to enforce the warrant and force the door. As soon as he began, Johnson shot him through the wooden door. A brief firefight broke out, and the team managed to return the wounded King to Aklavik where he eventually recovered.

Manhunt

A posse was then formed consisting of nine men, 42 dogs and of dynamite which they intended to use to blast Johnson out of the cabin if necessary. After surrounding the cabin they thawed the dynamite inside their coats. The common version states that this charge was thrown onto the roof of the cabin, collapsing it in the following explosion. After the explosion, the men tried to rush in. Johnson opened fire from a five-foot dugout beneath the ruins. No one was hit, and after a 15-hour standoff (ending at 4:00 A.M.) in the weather, the posse retreated to Aklavik for further assistance. Again, the RCMP investigative report partially contradicts this, claiming that the dynamite charge barely damaged the cabin, but it was later purposely destroyed to prevent him from returning to it, which may have led to the impression by some that the blast had destroyed it.

By this point, the news had filtered out to the rest of the world via radio. After being delayed because of blizzard conditions, the reinforced posse returned on January 14 to find that Johnson had left the cabin, and the posse struck out after him. Eventually, they caught up with him on January 30, surrounding him in a thicket. In the ensuing firefight, Johnson shot Constable Edgar Millen through the heart, killing him. Millen was later to have a tributary of the Rat River, Millen Creek, named for him. A memorial is located in the area. Once again they fell into retreat. The posse continued to grow, enlisting local Inuvialuit and Gwich'in who were better able to move in the back country. Johnson had clearly decided to leave for the Yukon, but the RCMP blocked the only two passes over the Richardson Mountains. That did not stop Johnson, who climbed a peak and once again disappeared.
