CHEYENNE - A television crew is in Cheyenne this week working on a documentary about the legendary Tom Horn and other notable names of the Old West.

Producer Conor McCarthy says plans are to air the documentary on The History Channel, perhaps as early as this spring.

McCarthy said the documentary will feature several hour-long episodes, one on Horn and another on Ellen Watson, better known as Cattle Kate.

Horn was hanged on Nov. 20, 1902, for the murder of an unarmed teen boy, but some maintain Horn did not kill the youth.
