Who Is the O'Brien Crime Family
The O'Brien crime family is a Boston-based organized crime group historically tied to the Irish Mob and the broader New England underworld. The organization is named after former boss James "Whitey" Bulger and associates linked to the Winter Hill Gang and South Boston criminal networks. Law enforcement agencies, including the FBI and the U.S. Department of Justice, have identified the group as part of the Patriarca crime family's influence area in some older federal cases, while newer indictments treat it as a distinct crew focused on drug trafficking, extortion, and racketeering. Public court filings and federal press releases describe the family's operations through a mix of legitimate businesses and street-level crews that move drugs, collect debts, and coordinate with other regional groups.
In recent years, federal prosecutors have continued to target members and associates through RICO cases, wiretap evidence, and cooperating witness testimony. The group's leadership structure has shifted over time, with younger figures stepping into roles once held by older gangsters who faced lengthy prison sentences or death. Investigators from the FBI's Boston Field Office and the Massachusetts State Police have documented connections between the O'Brien family and other gangs, including the Genovese and Bonanno families, in narcotics distribution and illegal gambling operations across New England.
Key Figures and Legal Actions
Notable Members and Associates
Key figures linked to the O'Brien crime family include James "Whitey" Bulger, Stephen Flemmi, Kevin Weeks, and several current and former associates named in federal indictments. Bulger, who was captured in 2011 and later convicted, was a central figure in Boston's organized crime landscape and is frequently cited in DOJ reports on the group's history. Other individuals have faced charges in connection with drug distribution, firearms offenses, and money laundering, with court records showing ties to legitimate businesses used to launder proceeds from criminal activity.
Federal grand jury indictments and sentencing memos provide details on the roles these individuals played in the organization's operations. For example, some associates have pleaded guilty to participating in a pattern of racketeering activity that included extortion, drug trafficking, and violent intimidation of rivals and witnesses. The U.S. Attorney's Office for the District of Massachusetts has publicly described the group's activities as part of a broader effort to dismantle organized crime networks in the region.
