There was violence by the strikers. Strikebreaker Pedro Armijo was murdered near the Aguilar tent colony. A mine clerk named Herbert Smith, scabbing in a Colorado Fuel and Iron mine, was brutally beaten near Trinidad. Strikers fired on the Forbes mining camp, where strike-breakers were living, and were dispersed by an infantry company. Four mine guards were killed at La Veta while escorting a scab. And on November 20, 1913, George Belcher, the killer of Lippiatt, was leaving a Trinidad drugstore, stopped on the corner to light a cigar, and was killed by a single rifle shot by an unseen gunman.
