Isam Dart walked out of his cabin on the morning of Oct. 4, 1900, and headed toward his corral. He didnât make it.
From behind a tree 120 yards away, an assassin fired a single rifle shot that struck Dart in the breast and severed his spine. The 42-year-old Dart died almost instantly, moaning âOh my God!â as he fell.
History has held notorious gunman Tom Horn responsible for the murder of Dart, who was a well-respected Black cowboy. Even though Horn was never arrested or even investigated for the killing, there is significant evidence to tie him to the killings of both Dart and Dartâs friend, Mat Rash.
