Back in Palm Beach, local authorities build what they believe is a solid case against Jeffrey Epstein and they turn it over to the FBI, confident the feds will investigate and prosecute Epstein as the local police feel he deserves. Victims ?from Florida, New York and New Mexico are interviewed by the FBI ?over the course of two years -- and ?they are assured that the wheels of justice are turning. But what eventually happens stuns Palm Beach police and the women who, despite fearing for their safety, opened up old wounds to cooperate with federal investigators. How did the millionaire from Palm Beach, accused of sexually abusing potentially over 30 girls and young women across the country, end up spending just over a year in a local jail cell that allowed to come and go almost as he pleased? Just who was behind the "sweetheart" deal Epstein got, leaving victims both angry and betrayed? And new information from ABC News shows federal investigators knew even more years ago than has been previously reported about allegations against Epstein -- this time, surrounding a 14-year old girl in New York.
