Sammy Gravano — Mob Underboss Turned Informant and Drug Boss
New York and Arizona, 1970s–2000s; multiple convictions, released 2017

Quick Facts
The Case
The Sammy Gravano case is not a single crime but a cluster of major American organized-crime prosecutions centered on Salvatore 'Sammy the Bull' Gravano, the former Gambino crime family underboss who became one of the most consequential federal cooperating witnesses in U.S. history before reoffending years later as the head of an Arizona ecstasy ring. Born in Brooklyn on March 12, 1945, Gravano rose through the ranks of the Gambino family under boss John Gotti, eventually admitting personal involvement in at least 19 murders committed in the service of the Mafia.
The Crime
Gravano's criminal career falls into two distinct chapters. The first is his decades of organized-crime activity in New York City, where he participated in murders, racketeering, extortion, loan-sharking and labor racketeering on behalf of the Gambinos. Among the federally charged killings discussed by prosecutors was the murder of Brooklyn contractor Eddie Garofalo, who was gunned down in 1990 after refusing to bow to mob demands in the construction industry.
The second chapter began after Gravano entered the federal witness protection program and ultimately resettled in Arizona. Federal and state investigators later determined that he had built and bankrolled an interstate ecstasy distribution network. According to reporting by ABC News on the Phoenix case, prosecutors said Gravano 'masterminded' an ecstasy ring that moved pills from Arizona to New York and was capable of distributing as many as 30,000 tablets per week.

The Victims
Because the Arizona prosecution was a drug-conspiracy case rather than a homicide, it has no single named victim. In the broader mob context, however, Gravano admitted to participation in 19 murders as part of his cooperation deal — a tally that includes mob associates, rivals and at least one civilian businessman, Eddie Garofalo. Many of these killings took place in and around New York City during the 1970s and 1980s as the Gambino family consolidated power under Paul Castellano and later John Gotti.
Investigation
The pivotal moment in the mob investigation came on November 13, 1991, when Gravano agreed to cooperate with federal prosecutors in the Southern District of New York. His decision — driven in part by recorded conversations in which Gotti disparaged him — transformed the government's racketeering case. Gravano's detailed inside testimony produced convictions not only of Gotti but of numerous other made members across the Five Families.
The Arizona investigation, by contrast, was a multi-agency narcotics probe focused on a large ecstasy pipeline. As described by the Mob Museum's account of Gravano's release, state and federal agents tracked the ring's operations until Gravano, his son Gerard, his wife Debra and his daughter Karen were all charged in 2000.
Trial and Verdict
Under his 1994 federal cooperation agreement, Gravano received a sharply reduced sentence of five years for his admitted role in 19 mob murders and a long list of other felonies. The Arizona case ended very differently. On June 29, 2001, Gravano pleaded guilty in Maricopa County Superior Court to leading the ecstasy operation, and in 2002 he was sentenced to 20 years in prison, with related federal drug convictions running concurrently. His wife and children also pleaded guilty in the case.
A detailed chronology of Gravano's criminal record compiled by organized-crime researchers documents how the Arizona convictions effectively erased the benefit of his earlier cooperation deal and returned him to long-term incarceration.
Today
Gravano was released from federal custody in September 2017 after serving most of his Arizona-related sentence. Since his release he has rebuilt a public profile as a commentator on organized crime, running a personal website and media platform and hosting the popular YouTube and podcast series 'Our Thing,' where he discusses Mafia history and his own past. A long-form interview series available on YouTube has drawn millions of views, and his daughter Karen Gravano became a reality-television figure on 'Mob Wives.' The case remains a touchstone in U.S. organized-crime history: the man whose testimony broke the Gambino family also became one of the most prominent examples of a cooperating witness who returned to serious crime.
