Buda (at that time known by the alias of Mike Boda) had eluded authorities at the time of the arrests of Sacco and Vanzetti, was experienced in the use of dynamite and other explosives, was known to use sash weights as shrapnel in his time bombs, and is believed to have constructed several of the largest package bombs for the Galleanists (Buda was also a suspect in the Preparedness Day Bombing of San Francisco July 22, 1916).
