Pietro Peter Panto was a pioneering labor leader who pledged to free the Brooklyn dockyards from Mafia racket control. On one occasion Panto drew more than 1,200 longshoremen to one of his rallies. The union reformer was warned to stop his campaign against mobsters but he continued to persevere. On the morning of July 14, 1939 Panto said goodbye to his girlfriend Anna Maffia at their residence at North Elliott Place in Brooklyn. He told her he was "going to meet a couple of guys I don't trust."
