Peter DiFronzo (May 13, 1933 – December 4, 2020) was an American man frequently identified in media and law-enforcement accounts as an associate of the Chicago Outfit, the organized-crime syndicate long active in the Chicago area. He is best known in public records as a brother of John DiFronzo, who has been described in reporting as a leader within the Outfit. Accounts of Peter DiFronzo's role rely on court records, investigative reporting and books about organized crime; many descriptions are framed as allegations or reported associations rather than convicted leadership positions.
Background and criminal convictions
Public records indicate that DiFronzo had prior felony convictions. In 1965 he was arrested in connection with interstate transportation of stolen property; later reporting notes he served time in federal prison, including a term at Leavenworth. Law-enforcement sources and later writers have described him as a "made man" within the Outfit, a term used informally to indicate formal induction into a Mafia family. These characterizations appear in criminal filings and investigative books, though the exact extent of any leadership role has been a matter of reporting rather than comprehensive public court findings.
Business ties and alleged activities
DiFronzo's family was associated with a trucking company in the Chicago area. Publicly available reporting names his wife, Josephine, as a co-owner of D&P Trucking, while authorities have asserted that the company and related businesses were influenced or controlled by family members. Investigations into the Outfit have historically focused on sectors such as waste hauling, trucking and construction for alleged extortion, bid-rigging and racketeering; accounts that mention DiFronzo link him to those patterns of enterprise-based criminal activity, often described as suspected or alleged in contemporary coverage.
Notable references and reporting
DiFronzo appears in several works about organized crime. He is mentioned in William F. Roemer Jr.'s book War of the Godfathers (1990), which examines inter-family conflicts and controls over Las Vegas and other rackets. Journalistic profiles and legal documents have periodically cited his name in discussions of the Chicago Outfit and its operations.
