Enemies of the Association soon fought back. George Henderson, the range detective who had accused Ella Watson, was murdered by rustlers near Sweetwater Creek in October 1890, an obvious taunt to the Association. The cattle barons soon tightened their control and hunted down those who tried to oppose them. The double lynching of the Averells was followed by the lynching of Tom Waggoner, a horse trader from Newcastle, in June 1891. A friend of Waggoner named Jimmy the Butcher, who was once arrested for rustling from the Standard Cattle Company, was also murdered. Range detective Tom Smith killed a suspected rustler, and when he was indicted for murder, political connections of the Association secured his release. These killings would precipitate more hostilities and violence in the years to come.
