The Agent Who Discovered Roy DeMeo

Retired Intelligence Detective Gary Jenkins brings you the best of mob history through his unique perspective on the mafia.
In this episode of Gangland Wire, Gary Jenkins sits down with author Craig McGuire to discuss his gripping book, Empire City Under Siege, a deep dive into three decades of FBI manhunts, mob wars, and organized-crime investigations in New York City.  

Craig explains how the project grew out of his collaboration with retired FBI agent Anthony John Nelson, whose career spanned the most violent and chaotic years of New York’s Mafia history. From Nelson’s early days as a radio dispatcher in 1969 to his transition into undercover and frontline investigative work, the book captures the gritty reality of law enforcement during the 1970s and 1980s. 

We explore how Nelson’s career mirrored the evolution of organized crime and law-enforcement tactics, including the rise of undercover stings, inter-agency cooperation, and the increasing role of technology. Craig highlights the close working relationship between Nelson and NYPD detective Kenny McCabe, whose deep knowledge of Mafia families and quiet professionalism led to major breakthroughs against organized crime. He tells how these two investigators wathced and uncovered the Gambino Family Roy DeMeo crew under Paul Castellano and Nino Gaggi. 

Throughout the conversation, Craig shares vivid, often humorous slice-of-life stories from the book—tense undercover moments, dangerous confrontations, and the emotional toll of living a double life. These anecdotes reveal not only the danger of the job, but the camaraderie and resilience that sustained agents and detectives working in the shadows.   The episode closes with a reminder that Empire City Under Siege is as much about honoring unsung law-enforcement professionals as it is about mob history. Craig encourages listeners to support true-crime storytelling that preserves these firsthand accounts before they’re lost to time.
