No episode in NYPD history surpasses the depravities of Louis Eppolito and Stephen Caracappa, two decorated detectives who covertly acted as mafia informants and paid assassins in 1980s Brooklyn. For more than ten years, the two moonlighted as the mob’s early warning alert system, leaking names of mobsters secretly cooperating with the government and crippling investigations by sharing details of surveillance, phone taps and impending arrests. When evidence of their wrongdoing arose in 1994, FBI officials failed to muster an indictment. The allegations lay dormant for a decade, but finally led to a resolution in 2009, nearly thirty years after their crimes took place. Join us for an event with Michael Cannell, author of "Blood and the Badge," as he shared this history and the new research and never-before-released interviews that contributed to his book. Michael Cannell is the author of "A Brotherhood Betrayed: The Man Behind the Rise and Fall of Murder, Inc.," and three other works of non-fiction. He has worked as an editor at The New York Times and contributed to The New Yorker and many other publications. Photo credit: Michael Weschler.
