This is a list of mafia-tied individuals and cooperating mafia-tied individuals authorities have stated have associations with, or who have made statements which directly implicated, Gianfranco Becchina for Cosa Nostra involvement. 

(Note:  This list is not complete and will be updated periodically as other names and details are released.)

Giovanni Brusca - Ex Capomafia of the San Giuseppe Jato family.  Incarcerated. Also known as "U' Verru" (in Sicilian) or Il Porco or Il Maiale, (In Italian: The Pig, The Swine) or lo scannacristiani (christian-slayer; in Italian dialects the word "christians" often stands in place of human beings). The information he provided regarding Becchina has not been made public though it appears to implicate Becchina with having had a relationship with Francesco Messina Denaro and fencing of antiquities.

Calculating and violent, Brusca is known to have tortured the 11-year-old son of a mafia turncoat or pentito to get him to retract statements made to the authorities in connection to the Capaci massacre.  After holding the boy hostage for 26 months, he strangled the child and dissolved his body in acid.  Brusca  once stated that he had killed "between 100 and 200" people with his own hands, but was unable to recall exactly how many murders he had participated in or ordered.

Brusca is also responsible for detonating 100 kilograms of TNT in 1992 under the highway between Palermo and the Punta Raisi airport in a bomb attack which murdered anti-Mafia magistrate and prosecutor Giovanni Falcone, Falcone's wife and five of his bodyguards. In 1993 Brusca mounted further bombing raids throughout mainland Italy hoping to intimidate politicians into reversing decrees for tougher jail regimes for incarcerated mafiosi. This wave of bombings in Florence, Milan and Rome left 10 people dead and injured 70 others.

Later, after his arrest, and through a series of strange accords, Brusca also turned informant, though much of his testimony has, at times, appeared to be self serving.  His testimony has afforded him controversial and exceptional treatment in direct contrast with his previous level of lethality. According to some of the testimony released, Messina Denaro was given the job of picking which paintings to target in the Florence bombing that ripped through a wing of the world famous Uffizi gallery because of his knowledge of art.    He is currently sentenced to life in prison.

Rosario Cascio - Mafia Associate to several bosses in multiple families including the fugitive Matteo Messina Denaro of the Castelvetrano family.  Incarcerated.  A Sicilian building magnate known as the "cashier of Cosa Nostra." At one time had a hit put out on him by mobster Angelo Siino, only to have Matteo Messina Denaro intervene on his behalf.

Cascio managed the family's economic activities and sub-contracts, and monopolized the concrete market and the sale of and construction equipment.  Through these he steered public contracts towards mafia businesses and managed an extortion racket which imposed sub contracts and labor.  In 1991 Cascio became connected with Becchina's Atlas cements Ltd., and took over as reference shareholder and director.

Vincenzo Calcara - exMafia soldier of the Castelvetrano family and collaborator of justice. Former protege of Francesco Messina Denaro.  Previously involved in international drug trafficking and money laundering which purportedly implicated the Vatican bank.  Calcara was originally tasked to kill antimafia Judge Paolo Borsellino with a sniper rifle but was arrested before he could carry out the plot. Involved in the trafficking of weapons, drugs, and political corruption he was offered a place in the witness protection program but refused.  Later Cosa Nostra determined his whereabouts and threatened his wife if she didn't get him to stop talking to authorities.  In 1992 Calcara and Rosario Spatola incriminated Becchina for alleged association with the Campobello di Mazara and Castelvetrano clans implying that there was a gang affiliate active in Switzerland whose role was to excavate and sell ancient artefacts on the black market.

Lorenzo Cimarosa -  Mafia declarant and law enforcement collaborator. Deceased.  Cimarosa died as the result of cancer while under house arrest. He was married to a cousin of mob boss Matteo Messina Denaro. Cimarosa told authorities about a warning message Becchina received from the mob in January 2012.  In that incident, someone fired shots from a shotgun at Becchina's door and left an intimidating gift of flowers. Cimarosa told authorities that he had heard through Francesco Guttadauro, nephew of the boss of the Castelvetrano family, that the incident was ordered by Matteo Messina Denaro himself for non-delivery of payments.  Cimorosa indicated that between 70 and 80,000 euros were paid through Becchina regularly. After his death the site where Cimorasa was buried has subsequently vandalised, perhaps as a warning to his wife and son. 

Francesco Messina Denaro - Capo Mandamento of the Castelvetrano family.  Deceased.  Died in hiding in 1998 while a fugitive from justice.  Father to Matteo Messina Denaro who took over his father's enterprise.  Francesco, also known as Don Ciccio, headed up the Castelvetrano family from 1981 until 1998 and was a member of the Cupola (Mafia Commission) of the Trapani region from 1983 until his death in 1998.  He was a close ally to the Corleone faction led by Salvatore "Totò" Riina and Bernardo Provenzano.  Purportedly had ties to Becchina relating to the theft, looting, and laundering of antiquities. 

Matteo Messina Denaro - Boss of the Castelvetrano family. Also known as "Diabolik." Fugutive.  Solidified his position in the mafia following the arrests of two of his predecessors, Salvatore "Totò" Riina in 1993 and Bernardo Provenzano in 2006.  A fugitive since 1993, he has been convicted in absentia for the Sicilian mafia's bombing campaign in the early 1990s, which killed magistrates and bystanders in Sicily, Rome and Florence which killed ten people and injured 93 others.  He once boasted "I filled a cemetery all by myself." According to Giovanni Brusca, Matteo Messina Denaro was the facilitator of the 1993 Uffizi gallery bombing in Florence.  In that incident a Fiat car packed with 100kg of explosives detonated killing six people, and destroying three paintings - two by Bartolomeo Manfredi and one by the Gherardo delle Notti.  He was also implicated in the bombing of the Basilica of St. John Lateran in Rome.  Mafia informants have claimed that Becchina allegedly passed envelopes of money to Denaro's brother in law and sister. Investigative seizures made by authorities in connection with this Cosa Nostra boss are so extensive it is hard to tell where the economy of western Sicily stops and Denaro’s mafia-controlled empire begins.  

Patrizia Messina Denaro - Sister of fugitive Boss and Capodonna representative of the Castelvetrano family.  Incarcerated.  Serving a 14 year and 6 months sentence for acting as stand in Capo Donna for her brother.  She was found guilty of being a full member of the Mafia and not an affiliate mafia. Several firms including an olive-oil company belonging to her and her husband were impounded and a number of bank accounts frozen.

Francesco Geraci - Mafia associate to Boss of Bosses Salvatore "Totò" Riina of of the Catania Family.  Incarcerated. There are two Cosa Nostra affiliates in custody with this same name.  One is the nephew and one is son of a deceased capomafia of the mafia family of Chiusa Sclafani.  It is unclear at this time which is cooperating with authorities. 

Giuseppe Grigoli - Mafia associate to the Castelvetrano family and law enforcement collaborator. Incarcerated. Also known as "Grigg." Former owner of a chain of Despar supermarkets in Sicily, convicted of being the entrepreneurial arm of fugitive Messina Denaro’s organisation using his retail and distribution group to launder Matteo Messina Denaro's cash.  Told the PM of the District Anti-Mafia Directorate of Palermo that between 1999 and 2006 he was given envelopes filled with money by Becchina which were to be delivered to Vincenzo Panicola, the husband of Matteo Messina Denaro's sister Patrizia Messina Denaro. These exchanges were said to have taken place in the former offices of 6GDo, the distribution chain confiscated just at the time of his arrest. 

Concetto Mariano - Mafia Associate of the Cosa Nostra Marsala family and law enforcement collaborator. Incarcerated. Mariano began cooperating with justice officials two months after being arrested.  Implicated Becchina in a plot to steal and fence in Switzerland the bronze statue of the Dancing Satyr, attributed by scholars to Praxiteles housed at the Piazza Plebiscito Museum in Mazara del Vallo.

Vincenzo Panicola - Mafia associate. -Incarcerated.  Brother-in-Law of fugitive Castelvetrano boss, Matteo Messina Denaro. Husband of Patrizia Messina Denaro, sister of the boss.  Worked with mafia associate to the Castelvetrano family, Giuseppe Grigoli. Convicted in 2013 to ten years in prison. Several firms, including an olive-oil company belonging to him and his wife, were impounded and a number of bank accounts frozen.

Santo Sacco - Mafia associate - Incarcerated.  A former UIL trade unionist and city councillor for Castelvetrano, Sacco was  sentenced to 12 years for is affiliations with Matteo Messina Denaro in the control of various business activities, including alternative energy as well as activities in support of the families of mobsters incarcerated.  Wiretaps of conversations with Becchina show collusion towards vote fixing and influence peddling in support of the election campaigns of Giuseppe Marinello and Ludovico Corrao. 

Angelo Siino - Mafia associate to the San Giuseppe Jato family. Incarcerated.  Often referred to as Cosa Nostra's "ex-minister of public works".  A businessman who oversaw whose principal duties were to oversee mafia public sector affairs through the illegal acquisition of public work contracts. Siino would receive the lists of public contracts before they became publicised and through through threats and extortion, insure that these contracts would be awarded to mafia influence coalitions, thereby controlling the market for public contracts in Sicily.

Rosario Spatola - Law enforcement collaborator.  Deceased. A former drug dealer who passed information in the 1990s to Judge Paolo Borsellino on drug trafficking in Trapani area and the role of the clan led by Boss Francesco Messina Denaro.  Believed by some not to be a true member of Cosa Nostra as his father was a policeman making his membership void.  In 1992 Spatola and Vincenzo Calcara, incriminated Becchina for alleged association with the Campobello di Mazara and Castelvetrano clans implying that there was a gang affiliate active in Switzerland whose role was to excavate and sell ancient artefacts on the black market.  Much of his testimony has been discounted as many were skeptical that he had actual knowledge or invented things to his own benefit.
