In Los Angeles the SLNA "stoutly defended" the McNamara brothers, who had confessed to dynamiting the "Los Angeles Times" building. William J. Burns, a labor spy, set up a network in Home, Washington to try to implicate Jay Fox in the matter, and was able to recruit a young anarchist, Donald Voss, into his spy ring. With Voss' help he was able to apprehend Matt Schmidt and Dave Kaplan, who were the McNamaras alleged accomplices.
