In this tense atmosphere, Falcone introduced an innovative investigative technique in the Spatola investigation, seizing bank records to follow "the money trail" created by heroin deals to build his case, applying the skills he had learned unravelling bankruptcies. He was probably among the first Sicilian magistrates to establish working relationships with colleagues from other countries, thus developing an early understanding of the global dimensions of heroin trafficking, while enhancing the ridiculously meagre investigative resources of his office. A colleague was astonished to discover that Falcone, who had no computers at his disposal, was personally recording the details listed on printouts of transactions that he had requisitioned from every bank in Palermo province.
