Several prisoners from Skagway were sent to McNeil Island, Washington at the turn of the century. There was an article written in the Dawson Daily News of August 14, 1905 that the Alaska Native prisoners were being kept isolated because they were all dying of consumption (tuberculosis) and were resigned to the fact that they would die in prison. The warden of the prison said that in his experience, the Alaskan natives had “a hereditary tuberculosis which was aggravated by the weather and confinement.”
They listed 12 Alaskan natives including the three which had been convicted of the Horton murders: Jim Kishtoo (Williams), Jack Klane (Mark Klanat), and Jim Hanson (Kebeth).
I believe the first two died around 1905 there and Kebeth died August 13, 1905 of consumption at age 28.
Land for the McNeil Island Cemetery was donated by island pioneers, Eric Nyberg and his wife, Martha, and the first of many burials was in October 1905. When the island’s residents were forced to leave in 1936, the cemetery was closed and all remains were exhumed and reburied in cemeteries on the mainland. So the actual resting place of these three is still unknown.
