Loosely organized gangs emerged in the 1910s. An Italian American gang known as the Mayfield Road Mob formed in Cleveland's Little Italy neighborhood about 1913. At roughly the same time, another Italian American gang, the Collinwood Crew, formed in the Collinwood neighborhood. This gang centered its activities around the intersection of St. Clair Avenue, E. 152d Street, and Ivanhoe Road. Out of a drug store in Cleveland's Big Italy neighborhood, notary public Angelo Serra ran the "Serra Gang". It was primarily an automobile theft ring which relied on Serra to forge titles to the cars and create fake vehicle registration plates. At one point in the mid-1910s, it did $500,000 ($ in dollars) a year in vehicle thefts. The gang also engaged in other crimes such as extortion, illegal gambling, the numbers racket, and robbery. 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.
