In this gripping episode of Gangland Wire, retired intelligence detective Gary Jenkins sits down with author Jonathan Dyer to explore one of the most complex and dangerous figures in Mafia history—Greg Scarpa, the Colombo family enforcer known as The Grim Reaper.
Dyer, whose career spans military intelligence, law, and education, brings deep insight into Scarpa’s remarkable—and chilling—dual role as both a ruthless mob killer and a prized FBI top echelon informant. Together, Gary and Jonathan unpack the moral ambiguities, betrayals, and calculated violence that defined Scarpa’s career in the turbulent world of organized crime.
Listeners will hear:
How Scarpa balanced loyalty to the mob with his covert cooperation with the FBI.   The structured, almost corporate way his crew operated—and how he enforced discipline with fear and bloodshed.
The darker corners of his personal life, including family ties, marriages, and the impact of his choices on his children.
The violent episodes, such as the murder of Mary Bari, underscore his brutality and the Mafia’s code of protection.
From Cold War–era law enforcement collusion to the inner workings of New York’s underworld, this episode reveals how Scarpa manipulated both sides of the law to maintain power.
Jonathan Dyer’s latest book, Greg Scarpa: Legendary Evil, offers the foundation for a conversation that will leave you questioning where law enforcement ends and organized crime begins.
