chase and death of Albert Johnson, who was estimated between 35 and 40 years. Sigvald had become obsessed with the notion that the authorities were still looking for him after evading conscription during the First World War. He had built a fortress-like cabin on Digby Island on the north coast of B.C. before disappearing. This author points out circumstantial evidence for this case. In August 2007, a forensic team assembled by Myth Merchant Films located and exhumed Johnson's grave near the cemetery in Aklavik, then conducted a modern forensic examination on his remains; these were documented in the documentary film The Hunt for the Mad Trapper and the book The Mad Trapper: Unearthing a Mystery by Barbara Smith. This team found that isotopic analysis of his teeth suggested he may have grown up in Scandinavia or the U.S. Midwest, that he had scoliosis which would have led to chronic back pain, that he was approximately 35 years of age, and that he had been struck multiple times in his final gun battle including his leg, thorax and a debilitating shot from behind through his pelvis. A spiral fracture of his femur supports the anecdote that a bullet had hit and exploded an ammunition pouch on his hip. His dental work was of very high quality for the time suggesting he was able to afford expensive state-of-the-art work at a major centre such as Chicago or New York. DNA samples were also obtained for comparison work. After the examination his remains were re-interred with full religious rites by both the local priest and native elders, something that had not been afforded to him at his original burial. While many people had offered convincing circumstantial and anecdotal evidence that they were related to him, the DNA analysis ruled out all of the candidates and his identity remains a mystery. In 2017, it was decided to attempt a familial DNA investigation; however, technical problems with the DNA eluded analysis until an adequate sequence was developed by Othram Inc. in 2021. Further investigation by Othram traced his ancestors to Sweden, linking him to multiple descendants of Gustaf Magnusson (1776–1853) and Britta Svensdotter (1781–1846), suggesting that he was either their descendant or the descendant of one of their close relatives. Many of his genetic matches traced their ancestry to the Swedish towns of Hånger, Kävsjö and Kulltorp. , further DNA samples and family history were
