Sal Maroni was the second-in-command of Falcone's Mob.
Although a mobster, Sal Maroni did have a softer side, getting married and having a son. After his son was in trouble during the Zero Year, Maroni ended up finding himself in the debt of Haley's Circus. This would be the first interaction between the Mob and the Circus, this was ironic because of Tony Zucco, Maroni's top enforcer, later attacking the circus. Following the Zero Year, Falcone's Mob began to fall and due to the GCPD getting more honest officers, Maroni, much like other mafioso, fell from his position. The gang was then consolidated into the Penguin's Empire.
