The earliest known Mafia boss in Rockford was Antonio Musso, who established his group during the
Prohibition era. Musso would step down as boss in 1957, due to ill health and was replaced by Joseph Zammuto. During his time in Rockford, Zammuto amassed significant wealth as a mobster and, in 1954, he purchased the
Dr. Pepper bottling plant in the city. Zammuto's
consigliere Joseph Zito was a brother to the
Springfield Mafia boss
Frank Zito. Zito had arrived in America during Prohibition along with his brother-in-law Jasper Calo, and his brothers settling in Springfield before moving he relocated to Rockford. Vince had risen to power during the 1950s, by controlling the family's illegal gambling rackets. After Vince's death, Sebastian Gulotta took over the family becoming boss. Gulotta was a longtime member of the Rockford family having been inducted into the family during Zammuto's reign. In the 1970s, Saladino associated himself with the Chicago Outfit's South Side/26th Street crew in committing many contract murders for the Chicago Outfit. On April 25, 2005, the
U.S. Department of Justice launched
Operation Family Secrets which indicted Frank Saladino alongside thirteen Chicago Outfit members and associates under the
RICO Act, including
Joseph Lombardo,
Nicholas Calabrese,
Frank Calabrese Sr. and
James Marcello. ==Historical leadership==
