President William McKinley ordered U.S. troops from Montana into the area. The miners were rounded up and once again herded into a bullpen. Some of the miners were released after denying that they belonged to any subversive organization. Boyce was charged with conspiring to blow up the concentrator. Boyce had been in Wardner conferring with local union officers only a week before the explosion. In 1906, former union member and Boyce business associate Harry Orchard told a court that he knew Boyce had planned and approved the bombing of the Bunker Hill and Sullivan Mine.
