Isam Dart

"[3] He and his partner Mat Rash were gunned down in separate events and were believed to have been assassinated by Tom Horn, a hired gunman.

In 1927, a biographical fiction book about a Black cowboy was published that erroneously stated that Dart was born in Arkansas nine years before his birth.

[5] He worked as a cook at a railroad construction camp between Green River and Rock Springs of the Wyoming Territory.

[1] In 1883, Dart was a member of a cattle drive to the Browns Park area[4] in northwestern Colorado, near the borders with Wyoming and Utah.

[5] Due to the lack of law enforcement, the area attracted outlaws, like Butch Cassidy and the Wild Bunch, which meant that ranchers were reluctant to take full use of the open range land.

[1] While working for the Bassetts, Dart was a ranch hand who also cooked meals, washed laundry, cut wood, and performed other household duties.

In one case, Dart was said to have been arrested by a deputy sheriff, who drove the two men in a buckboard wagon and headed for jail.

[3] In addition to being a cattle rancher and rustler, Dart captured, broke in, and sold wild horses that were branded with "I D Bar".

Dart was taken to a jail north of Steamboat Springs on Hahns Peak, where he awaited the start of the trial for arson in 1890.

[1][6] In 1898, Dart was a member of a posse that tracked down men who had killed a teenager, Willie Strang, in Browns Park.

Horn assumed the persona of a horse buyer to gain evidence of rustlers, which was found to include Dart.

After Matt Rush was killed on July 8, 1900, Dart invited his friends—including Sam and George Bassett—to stay at his cabin, which he assumed would be safe.

[1] By the time of his death, Dart and his partner Mat Rash were said to have amassed two good ranches and a lot of cattle and horses.

[7] An impaneled jury found that "Isam Dart came to his death, by a rifle shot at the hands of a party unknown".
