01 / The Detroit story
The Detroit story
Giuseppe Zerilli left Terrasini, Sicily, at 17 and settled in Detroit in 1914 among many other Sicilian immigrants, working at first as a laborer for the Detroit Gas Company. During Prohibition he joined the bootlegging crews that smuggled liquor across the Detroit River from Windsor, working alongside his relatives and fellow Terrasini natives, including his brother-in-law William Tocco. After the Crosstown mob war of 1930–1931 ended with the killing of rival Chester LaMare, Detroit's Sicilian factions merged into what became known as the Detroit Partnership, and by 1936 Zerilli had operational control. For four decades he presided over gambling, loan-sharking, union and legitimate business interests across southeast Michigan, Windsor and Toledo, while largely avoiding prison. In 1956 Detroit's family was given a seat on the Mafia's national Commission. His family's interest in Hazel Park Raceway, opened in 1949, was a major source of money in an era when racetracks were Michigan's only legal gambling. He died of natural causes in 1977 and is buried in Mount Olivet Cemetery.
