Although the Provenzanos withdrew in favor of giving the Matrangas a cut of waterfront racketeering, by the late 1880s, the two families eventually went to war over the grocery and produce businesses held by the Provenzanos. As both sides began employing a large number of Sicilian mafiosi from their native Monreale, Sicily, the violent gang war began attracting police attention, particularly from New Orleans police chief David Hennessy who began investigating the warring organizations. Within months of his investigation, Hennessy was shot by several unidentified attackers while walking home on the night of October 15, 1890; he died of his wounds less than twelve hours later, having failed to identify his assailants beyond allegedly claiming "The Dagoes shot me". The shooter was never positively identified and the assassination remains unsolved.
