Biggest Snitches in Italian MOB History – ht
:
The courtroom was packed. October 15th, 1991. Federal courthouse in Brooklyn. Every seat filled with reporters, prosecutors, defense attorneys, family members. At the front of the room sat John Gotti, 51 years old, boss of the Gambino crime family, the most powerful mobster in America.
Gotti was wearing an expensive suit, tailored, perfect. His hair was perfectly styled. He looked confident, almost smug. Gotti had beaten three previous federal prosecutions. The press called him the Teflon Dawn because charges never stuck. Gotti believed he’d beat this case, too. Believed his lawyers were better than the prosecutors. believed witnesses wouldn’t testify, believed he was untouchable.
Then the prosecution called their star witness. The courtroom doors opened. US marshals escorted a man to the witness stand. The man was 46 years old, short, stocky, wearing a prison jumpsuit. He didn’t look at Gotti, didn’t acknowledge the audience, just walked to the stand and sat down.
The prosecutor asked, “Please state your name for the record.” Salvator Graano, “What is your occupation?” I was the under boss of the Gambino crime family. I worked directly under John Gotti for 5 years. The courtroom erupted. Reporters scrambled to take notes. Defense attorneys objected. Gotti’s face turned red.
Because Salvatore Sammy the Bull, Graano, Gotti’s under boss, his second in command, his trusted friend, was testifying against him. Was about to detail every crime, every murder, every conspiracy, was about to destroy the Teflon Dawn with 16 days of testimony that would send Gotti to prison for life. Sammy the Bull wasn’t the first major mafia informant, wasn’t the last, but he was the most consequential.
His cooperation didn’t just convict one boss. It shattered the myth of Omera, the code of silence that had protected the mafia for a century. After Sammy, the floodgates opened. Dozens of mobsters cooperated, testified, destroyed their own organizations from within. The mafia, which had survived for generations by enforcing absolute silence, was being destroyed by its own members becoming informants.
This is the story of the biggest snitches in Italian mob history. The men who violated Omera, who testified against their bosses, their friends, their families, who traded loyalty for freedom, and who in doing so destroyed the American mafia as a functioning criminal organization. From Joe Velace in 1963 to Michael Francesci walking away in the 1990s, these are the informants who broke the code and broke the mob.
Joe Velace, the first to break. Omera. Joseph Velace wasn’t a boss, wasn’t a captain, was just a soldier in the Genevas crime family. low-level, unremarkable, had killed some people, made some money, nothing special. But in 1963, Joe Velace became the first maid member of the Italian mafia to publicly testify about the organization’s existence and structure.
The background. Valishi was arrested in 1960 on narcotics charges was facing significant prison time. While in prison awaiting trial, Valashi became convinced that his boss Veto Genevvesi had put a contract on him. Believed Genevvesi thought Valishi was cooperating with authorities. In June 1962, while in federal prison, Valashi killed another inmate, John Sa, because Valashi believed Sa was there to kill him on Genevy’s orders.
Sa probably wasn’t a hitman. Velashi likely killed the wrong person out of paranoia. After killing Sa, Velashi knew he’d never get out of prison. facing life sentence decided to cooperate with federal authorities. The testimony in September to October 1963, Valishi testified before the Senate Permanent Subcommittee on Investigations.
His testimony was televised. Millions of Americans watched. Valiche revealed the existence of Black Kosa Nostra, our thing, the formal name of the Italian-American mafia. The structure, bosses, under bosses, captains, soldiers. The commission, governing body of the five New York families.
The initiation ritual, burning saint card, blood oath. The rules, oma, code of silence, no cooperation with law enforcement. The impact Valishi’s testimony didn’t lead to many immediate prosecutions. He was too low-level to have detailed knowledge of specific crimes. But his testimony changed public perception. Before Velashi, the FBI officially denied the mafia existed.
After Velachi, the FBI couldn’t deny it anymore. Velashi lived in protective custody until his death from natural causes in 1971. Was the first, but not the last, to break Omar. Why he snitched? Paranoia and fear. Believed he was going to be killed. Cooperated to save himself. Body count as informant.
No significant prosecutions directly resulting from his testimony, but open door for future informants. Jimmy the Weasel. Fatiano, the first boss to cooperate. Aladena, Jimmy the Weasel. Fratiano was acting boss of the Los Angeles crime family, was the highest ranking mobster to cooperate with authorities up to that point.
Fratiano was born in 1913, rose through the ranks of the LA family, became acting boss in 1977, but his position was precarious. Other members wanted him out. Fratiano learned there was a contract on his life in 1977. Facing both legal charges and a mob hit, Fratiano decided to cooperate with the FBI. Fatiano testified in multiple trials from 1978 to 1987, provided evidence about Los Angeles and San Francisco mob operations, testified about murder contracts, and organized crime activities, detailed relationships between families.
Fratiano’s cooperation led to convictions of multiple mobsters, including several LA family members. Chicago outfit figures, various associates and soldiers. More importantly, Fatiano proved that even bosses could be turned. Showed that nobody was too high ranking to cooperate. Fraatiano lived in witness protection until his death in 1993 at age 79.
Why he snitched self-preservation contract on his life plus legal pressure made cooperation the only survival option body count as informant approximately 10 to 15 major convictions directly from his testimony. Sammy the Bull Graano the underboss who destroyed Gotti Salvatore. Sammy the Bull Graano was under boss of the Gambino crime family under John Gotti.
His cooperation was the most devastating in mafia history up to that point. Sammy was made in 1976. Rose rapidly. By 1990 was Gotti’s under boss, second in command of America’s most powerful crime family. Was involved in 19 murders. Was a feared and respected figure. But Sammy had a problem. Gotti was bringing heat. The boss’s high-profile, media attention, and reckless behavior were attracting FBI scrutiny.
Worse, FBI had recordings of Gotti badmouthing Sammy. Gotti had been recorded insulting Sammy, questioning his loyalty, blaming him for problems. When Sammy heard those tapes played by prosecutors as part of legal proceedings, he realized Gotti was willing to sacrifice him. In November 1991, Sammy agreed to cooperate. His testimony was devastating.
Testified for 16 days, detailed murder conspiracies, explained Gambino family structure, described Gotti’s role in ordering hits. Gotti was convicted on all counts, sentenced to life without parole, died in prison in 2002. Other prosecutions. Sammy testified in multiple trials, helped convict 37 mobsters, destroyed significant portions of Gambino and Columbbo family leadership.
Sammy’s cooperation shattered Omea. If an under boss, a man who’d killed 19 people, who’d been loyal for 25 years, could cooperate, anyone could. After Sammy, dozens of mobsters flipped. The code was broken. Sammy entered witness protection, started New Life in Arizona, but in 2000 was arrested for running an ecstasy distribution ring, was convicted, served additional prison time, released in 2017, now lives openly, does interviews, runs a podcast.
Why he snitched? Combination of self-preservation, facing life sentence, and anger at Gotti. Felt betrayed by the boss’s insulting recordings. Body count as informant. 37 major convictions directly from his testimony. Indirectly inspired dozens of other informants. Philip Crazy Phil Leonetti, the under boss who destroyed Scaro.
Philip Leonetti was under boss of the Philadelphia crime family under his uncle Nicodemi Scaro. His cooperation destroyed the Philadelphia mob. Leonetti was born in 1953. Was brought into the life by his uncle Nikki Scaro. Was made in 1980. Became under boss in 1986 at age 33. was involved in 10 murders. Scarfo’s leadership was brutal and paranoid.
Between 1980 and 1989, Scaro ordered the murders of 30 plus people, including many family members. The violence was internal. Scaro was killing his own people over minor infractions. Leonetti watched his uncle destroy the family. Realized Scaro was insane. realized eventually Scarfo would kill him too.
Arrested in 1987 on racketeering charges, Leonetti initially planned to fight the case. But watching his uncle’s paranoid behavior, Scaro even ordered hits on family members while in prison. Leonetti decided to cooperate in 1989. Leonetti testified about 10 murders. He participated in Scaro’s leadership and decision-making Philadelphia family structure and operations relationships with other families.
The impact Leonetti’s testimony led to Scaro convicted, sentenced to 55 years, died in prison 2017. Multiple Philadelphia family members convicted, essentially destroyed. Philadelphia family’s leadership. Leonetti entered witness protection. Was released from prison in 2015 after serving reduced sentence. Now lives freely.
Why he snitched? Combination of facing life sentence and recognizing his uncle was insane and would eventually kill him. Body count as informant. Approximately 12 to 15 major convictions including his uncle, the boss. Alance Alib Persico, the boss’s son. Alons Persico was the son of Columbbo family boss Carmine the snake Persico.
His cooperation was particularly shocking because family members, especially boss’s sons, were supposed to be the most loyal. Wait, I need to correct this. Alons Persico didn’t cooperate. Let me replace with an actual informant. Leonid Lenny Dei Maria multiple families damaged. Actually, let me use a more significant informant.
Vincent Vinosian Polarmo de Cavalcante boss who flipped. Vincent Polalmo was acting boss of the De Cavalcante crime family, the real life inspiration for the Sopranos. His cooperation was unusual because bosses rarely flipped. Polarmo became acting boss of the De Cavalcante family in 1999. The family controlled operations in New Jersey, was smaller than the five New York families, but still significant.
Polarmo was facing RICO charges, life sentence, and had personal problems. His wife was sick. His children needed him. In 1999, facing overwhelming evidence, Polarmo agreed to cooperate, wore a wire, recorded conversations with other mobsters, testified at trials. Polarmo’s cooperation, convicted multiple De Cavalcante members, provided intelligence about New York families, helped dismantle significant portions of De Cavalcante operations.
Polarmo entered witness protection. lives under assumed name. Why he snitched facing life sentence plus wanting to be there for sick wife and children. Body count as informant approximately 8 to 10 convictions. Michael Franazi, the made man who just walked away. Michael Franazi is unique on this list because he didn’t testify, didn’t cooperate, didn’t wear wires, just walked away.
Michael was born in 1951, son of John Sunny Francesi, Columbbo family under boss. Michael was made in 1975, became a captain, created the gasoline bootlegging scheme that made him millions. By the mid 1980s, Michael was generating approximately $8 million weekly, roughly $25 million in 2024. Michael was arrested in 1985, convicted on racketeering charges, faced long prison sentence, prosecutors offered deal, cooperate, testify, get reduced sentence.
Michael refused to cooperate, wouldn’t testify, wouldn’t wear a wire, wouldn’t give up anyone. But when released from prison in 1994 after serving 7 years, Michael didn’t return to the life, walked away, became a Christian, started motivational speaking career, wrote books, made money legitimately. Michael’s situation was unusual.
didn’t testify against the family, didn’t cooperate with prosecutors, but also didn’t return to organized crime, walked away, and stayed away. Typically, the mob kills people who leave. But Michael had advantages. His father, Sunny, was still alive and respected. Michael had made the family millions. Over the years, Michael hadn’t testified or cooperated.
The family was weakened by prosecutions and couldn’t pursue everyone. As of 2026, Michael is still alive, age 74, runs a successful YouTube channel, does podcasts, speaks publicly, makes money telling stories about his mob days, but never names names, or provides information that could be used in prosecutions. Why he’s on this list? Michael didn’t snitch in the traditional sense, but he violated the code by leaving the life, by talking publicly about the mafia, though not providing prosecutable information, by becoming a public figure who profits
from his past. Some mobsters consider this a form of cooperation. Others respect that he didn’t testify. It’s complicated. Body count as informant, zero. never cooperated or testified. Anthony Gaspipe Casso, the underboss who destroyed his own deal. Anthony Casso was under boss of the Lucesi crime family.
His cooperation could have been the most significant in mob history, but Casso destroyed his own deal through lies and murder. Casso was made in 1974, became under boss in 1991, was involved in 36 plus murders, was known for extreme paranoia and violence. Arrested in 1993, Casso agreed to cooperate in 1994. Prosecutors were thrilled.
Casso had knowledge of dozens of crimes across multiple families. Casso’s cooperation failed because he lied repeatedly on the stand. He tried to order murders from prison even after cooperating. He provided false information that damaged prosecutions. Prosecutors couldn’t use him as a witness because he wasn’t credible.
In 1998, prosecutors withdrew Caso’s cooperation agreement. He was sentenced to life imprisonment in solitary confinement, died in prison in 2020. Caso’s failed cooperation actually hurt the prosecution of other mobsters. His lies and unreliability made it harder to use his information. Why he snitched self-preservation but couldn’t control himself enough to make cooperation successful.
Body count as informant, minimal. His lies destroyed most prosecutions that relied on his testimony. John Junior Gotti, the boss’s son, who almost cooperated. John Gotti Jr., son of John Gotti, was acting boss of the Gambino family after his father’s imprisonment. Junior faced multiple trials in the 2000s. Junior was made in 1988.
Became acting boss in 1992 after his father was convicted. Arrested multiple times in the 1990s to 2000s. Rumors persisted that Junior was considering cooperation. Prosecutors offered deals. Junior’s trials ended in mistrials. Juries couldn’t reach unanimous verdicts. Eventually, prosecutors stopped trying to convict Junior.
He claimed he’d left the life, retired, went legitimate. Junior has never cooperated or testified, but like Michael Franesi, he’s walked away, does interviews, defends his father’s legacy, makes money from his mob heritage without providing prosecutable information. why he’s on this list. Junior didn’t snitch, but the fact that he was rumored to be considering it, that prosecutors thought they could flip John Gotti’s son, shows how broken Omeaha had become by the 2000s.
Joseph Big Joey Msino, the boss who wore a wire. Joseph Msino was boss of the Bonano crime family. Was the first boss of a New York family to cooperate with authorities while still boss. Msino became boss in 1991. Ran the family successfully for 13 years, but in 2004 was facing death penalty on murder charges.
In 2004, facing potential execution, Msino agreed to cooperate. wore a wire. Recorded conversations with other mobsters, including Columbbo family boss Vincent Vinnie Gorges Bashiano. Msino’s recordings led to conviction of Vincent Bashiano, sentenced to life, multiple other Banano and Columbbo convictions, complete dismantling of Banano family leadership.
Msino was sentenced to life in prison. Death penalty taken off table due to cooperation. Is currently in protective custody in federal prison. Why? He snitched. Death penalty. Cooperated to avoid execution. Body count as informant. Approximately 12 to 15 convictions, including the boss of another family. Michael Mickey Scars. De Leonardo.
The Gambino captain. Michael D. Leonardo was a captain in the Gambino family. His cooperation provided detailed intelligence about Gambino operations in the 2000s. Deleonardo was made in 1988, became captain in the 1990s, was involved in various criminal enterprises, arrested in 2002. Deleonardo agreed to cooperate, testified in multiple trials.
Deleonardo’s testimony helped convict multiple Gambino family members, associates of other families, corrupt officials, and business people. Deleonardo is in witness protection. Why he snitched facing long sentence plus wanted out of the life. Body count as informant approximately 10 to 12 convictions. After Sammy the Bull’s cooperation in 1991, the floodgates opened.
Dozens, eventually hundreds of mobsters cooperated. Some notable posts Sammy informants. 1990s, multiple Columbbo family members during the Columbbo Wars. Various Gambino soldiers and associates, Lucasi family members, Genevvesi associates, 2000s. Bonano family members after Msino flipped de Cavalcante members Philadelphia family members Chicago outfit associates 2010s to 2020s continued flow of informants across all families street level soldiers cooperating to avoid long sentences associates turning to save themselves.
By 2020 cooperation had become routine. The code of Omera, once absolute, was now optional. Mobsters expected that people would flip, built that expectation into their operations. Looking at all these informants, common factors emerge. Factor one, self-preservation. Every informant faced significant prison time or death. Cooperation was survival.
Factor two, betrayal. Many felt betrayed by their organizations. Gotti insulting Sammy. Scarfo’s paranoid violence. Bosses sacrificing subordinates. Factor three, family. Many had wives and children they wanted to see. Life in prison meant abandoning family. Cooperation meant reduced sentence and eventual freedom.
Factor four, money. The mafia doesn’t take care of imprisoned members families like it used to. Informants who cooperate keep seized assets or get books/mov deals. Factor five, weakness of omarea. Once the first few high-profile members cooperated, it became easier for others. The taboo was broken. The wave of informants from 1991 to 2020 destroyed the American mafia as a functioning organization.
Before informants 1960 to 1990, five families in New York plus families in other cities. Thousands of maid members. Billions in annual revenue. Significant political and law enforcement corruption. Effective enforcement of omare ta after informance 1991 to 2024. Families still exist but greatly weakened.
Hundreds of maid members down from thousands. Revenue significantly reduced. Less corruption capacity. Omera Ta effectively dead. The biggest snitches, Velacei, Fatiano, Sammy, Leonetti, Msino, and others didn’t just betray their organizations, they destroyed them. showed that the code of silence was breakable, that anyone could be turned, that loyalty was conditional.
Joe Velace broke Omera in 1963, was the first maid member to testify publicly, opened the door. Jimmy Fatiano followed in 1977, showed bosses could flip. Sammy the Bull exploded the floodgates in 1991, destroyed Gotti, and shattered the myth of absolute loyalty. After Sammy, dozens more followed.
Leonetti, Msino, Dillionardo, hundreds of soldiers and associates, all breaking the code, all trading loyalty for freedom. These informants destroyed the American mafia. Not through violence, not through competition, but through cooperation with the enemy, law enforcement. They testified, wore wires, provided evidence, convicted their bosses, their friends, their families.
Why did they do it? self-preservation, betrayal, family, money, fear, all the human motivations that organized crime tries to suppress through codes and violence and tradition. But ultimately, they did it because the code was always a lie. Omera demanded absolute loyalty to an organization that would sacrifice you without hesitation when you became inconvenient.
The informants just figured this out before the organization killed them. The biggest snitches in Italian mob history weren’t villains, weren’t heroes, were just criminals who chose survival over death, freedom over life in prison, self-interest over organizational loyalty. They broke the code and in breaking it broke the mob.
