—PRETTY BOY FLOYD TO SPECIAL AGENT SAM McKEE The story of the Kansas City Massacre as told by Michael “Jimmy Needles” LaCapra was everything Hoover could have wanted. Pacing a Wichita, Kansas, jail cell in the predawn hours of September 1, LaCapra told agents he had learned details of the massacre from his brother-in-law, one of the mob boss Johnny Lazia’s henchmen. What happened, LaCapra said, was this: Late on the night of June 16, 1933, barely two hours after learning FBI agents were bringing Frank Nash to Kansas City the next morning, Verne Miller had driven to Union Station. The FBI knew this much was true; they had traced calls Miller made from a pay phone outside the station around midnight. But surveying the ground for the rescue was only one reason Miller drove to the station, LaCapra explained. The other was to see Johnny Lazia, who held court at the station’s Harvey Restaurant. According to LaCapra, Miller asked Lazia for men to help him rescue Nash. Lazia demurred, saying he didn’t want the heat that would bring.
