In late April 1919, at least 36 booby trap dynamite-filled bombs were mailed to a cross-section of prominent politicians and appointees, including the Attorney General as well as justice officials, newspaper editors and businessmen, including John D. Rockefeller. Among all the bombs addressed to high-level officials, one bomb was addressed to the home of a Department of Justice Bureau of Investigation (BOI) field agent once tasked with investigating the Galleanists, Rayme Weston Finch, who in 1918 had arrested two prominent Galleanists while leading a police raid on the offices of their publication "Cronaca Sovversiva".
