James T. Licavoli, who became boss of the Cleveland family after Scalish's death, hired hitman Ray Ferritto to kill Greene.
Much of the family's weakening can be attributed to Jimmy Fratianno, who turned government witness and provided the Federal Bureau of Investigation (FBI) with incriminating information on the organization.
[6] Following a series of convictions, including those of bosses Licavoli, Angelo Lonardo and John Tronolone, the Cleveland family nearly ceased to exist during the 1980s and 1990s.
[8] Semi-organized Sicilian American- and Italian American-run "Black Hand" extortion rackets first emerged in Cleveland, Ohio, around the year 1900.
After a series of Black Hand-related murders in the city in 1906, the Italian squad largely suppressed this first expression of organized crime in Cleveland.
[11] Elsewhere in Little Italy,[12][b] notary public Angelo Serra oversaw a gang primarily specializing in auto theft that at one point yielded $500,000 ($14,000,000 in 2023 dollars) a year.
[25] The brothels, speakeasies and gambling halls of Little Hollywood became the favorite hangouts of small gang leaders throughout Cleveland, many of whom established their offices in the city's tiny red-light district.
Initially establishing themselves as legitimate businessmen, the Lonardos and the Porrellos dabbled in various criminal activities including robbery and extortion but were not considered a major organization prior to Prohibition.
In 1927, hostilities between the Lonardos and the Porrellos escalated as the families competed in the manufacture of corn sugar, the prime ingredient in bootleg liquor.
They vied for control of the most lucrative rackets outside of the corn sugar business, which included gambling, the most profitable hustle for crime families of the period after bootlegging.
[30] In 1931, Milano joined the National Crime Syndicate, a network of powerful criminals which included Charles "Lucky" Luciano and Meyer Lansky.
[30] Alfred Polizzi, another leading member of the Mayfield Road Mob, seized power and reigned as boss until 1944, when he himself was convicted of tax evasion.
Members of the Collinwood Crew included Alfred "Allie Con" Calabrese, Joe "Joey Loose" Lacobacci, Butchie Cisternino.
[32] The family helped finance the construction of Las Vegas' Desert Inn casino hotel in the late 1940s and received a percentage of profits from the resort in exchange for providing protection.
[36] During Licavoli's reign, an Irish gangster named Danny Greene began competing with the Cleveland family for control of the city's rackets.
[37] Greene partnered with John Nardi, a rogue Mafia associate and Teamster, who arranged the murder of Calogero "Leo Lips" Moceri, Licavoli's underboss.
[37] Moceri disappeared after attending a Feast of the Assumption festival in Little Italy on August 22, 1976; his blood-stained car was found in Akron days later, although his remains were never recovered.
[45] In 1978, the CDP warned then-Mayor Dennis Kucinich that the Cleveland family had put out a hit on him because of some of his initiatives were hindering their criminal activities.
[48][49][50] The Pittsburgh family emerged victorious after the disappearances of Cleveland capo Charles "Charlie the Crab" Carabbia in December 1980 and his crew's top hitman, Joseph DeRose, Jr., in April 1981.
[56] After Tronolone's death, Anthony "Tony Lib" Liberatore took over the remnants of the Cleveland family until he was imprisoned for racketeering and money laundering in 1993.
[55][57] Following the imprisonment of Liberatore, two mafiosi who had been inducted into the family by Angelo Lonardo in 1983 – Joseph "Joe Loose" Iacobacci and Russell "R.J." Papalardo – became the leading figures in the Cleveland Mafia.
[55] Iacobacci, along with Alfred "Allie" Calabrese, was convicted of bank fraud and sentenced to three years in federal prison in 1995, during which time Papalardo served as acting boss of the family.
[55][58][59] Delmonti covertly recorded over 500 audio and videotapes which led to the seizure of $100,000 in illicit gambling money, $250,000 in stolen vehicles and 700 kilograms of cocaine, and over a hundred convictions in Cleveland and Rochester between 2000 and 2002.
