Arctic, or if he was actually responsible for interfering with the trap lines as alleged. Identity The RCMP sent a series of photographs throughout Canada and the United States in an unsuccessful effort to learn his real identity, which has never been definitively established. In the 1930s, the initial investigation about the identity of Albert Johnson primarily focused on an obscure individual named Arthur Nelson. Details of Nelson's life were recorded by Yukon researcher and author Richard North. Nelson apparently travelled from Dease Lake, British Columbia, up into the Yukon in the 1927 to 1931 period. He had similar guns (a Savage Model 99, a .30-30 Winchester calibre lever action rifle, a sawn-off Iver-Johnson 16 gauge shotgun and a sawn-off Winchester Model 58 .22 Long Rifle) as Albert Johnson. Nelson was also remembered by Kaska Dena elders Art John Sr. and others who knew him by the alias "Mickey Nelson" when he trapped and prospected in the Ross River region in west-central Yukon. North's 1989 book Trackdown put forward his theory that Albert Johnson, Arthur Nelson, and a North Dakota repeat criminal by the name of John Johnson were one and the same person. John Johnson did time in San Quentin Prison and Folsom Prison, and his physical description is well documented and similar to the Mad Trapper's. North traced John Johnson's identity back to Norway. "Johnny Johnson" was born Johan Konrad Jonsen (1898) in Bardu, Norway north of the Arctic Circle. However, the Mad Trapper's expensive dental work were not likely to belong to the criminal Johnson. Also, DNA tests involving John Johnson's great-nephew Ole Getz disproved that Johnny Johnson and the Mad Trapper were the same people. The Johnston family of Pictou, Nova Scotia have long believed that Albert Johnson is actually Owen Albert Johnston, a relative who had left Pictou at the beginning of the Great Depression to find work in the United States. The family's last letter from Johnston was posted from Revelstoke, British Columbia early in 1931. They never heard from him again. According to a 2009 radio interview a relative was arranging for DNA tests. Previous theories were challenged with the release of Mark Fremmerlid's book What Became of Sigvald Anyway. He proposed too many coincidences to ignore the possibility of Sigvald Pedersen Haaskjold from Norway emerging as Albert Johnson. Sigvald was last known as a highly self-sufficient 32-year-old in 1927, years before the
