This day, September 30, 1915 was an unfortunate one for a White Pass & Yukon Route section crew. One of the four, Tom Bokovitch was a German prisoner of war, working his way through the war in the Yukon. With him were Henry Cook, Patrick Kinslow and George Lane.
The four men stopped for a lunch break on the track near Whitehorse when they were approached by a Russian man Alex Gagoff. Gagoff may have thought they laughed at him, in any event, he shot them all dead. He then turned himself in to the NWMP in Whitehorse. He was subsequently tried and hung on a cold (-36 below zero) day in Whitehorse on March 10, 1916.
