No one can deny that mob boss James "Whitey" Bulger and Stephen "The Rifleman" Flemmi are two of the most brutal killers in American history—not even the two gangsters themselves. But a jury denied the Davis family closure for the slaying of Debbie Davis, Flemmi's beautiful young girlfriend, who went missing in 1981 and whose remains were found nearly twenty years later under the Neponset River Bridge in Quincy, Massachusetts. Now serving a life sentence, Stephen Flemmi testified in graphic detail how he lured Debbie to a house in South Boston where Bulger jumped out of the shadows and strangled her to death. Flemmi then extracted her teeth and buried her body by the Neponset River while Bulger watched. Bulger wanted Debbie dead, Flemmi claimed, because she knew that the two men were meeting with an FBI agent named John Connolly. That, and he might have been jealous of the time Flemmi and Debbie were spending together. Throughout his trial, Bulger stubbornly insisted that he never would have committed the dishonorable act of killing a woman. In the end, it was one stone-cold murderer's testimony against another's. In Impact Statement, veteran journalist Bob Halloran looks at the devastating impact Bulger and Flemmi have had on the Davis family, whose longstanding relationship with the two mobsters cost them a father, two sisters, and a brother.
