 In the late 1910s, the "Benigno Gang" formed under Dominic Benigno in Little Italy.The gang specialized in payroll robberies, and in 1919 and 1920 monopolized payroll robberies by intimidating or murdering anyone who tried to pull off a heist without Benigno's permission.A less organized and more fluid criminal organization was the "reservoir gang", a group of criminals engaged in armed robbery, automobile theft, burglary, and other property crimes which met at Cleveland's Baldwin Water Treatment Plant reservoir in order to plan crimes, exchange stolen goods, and disperse profits from crime.
