Congressman Hales Boggs was a member of the Warren Commission. In 1972 the twin engine airplane in which Boggs was traveling over a remote section of Alaska disappeared. The plane presumably crashed and was never found.
After Hale's disappearance, Lindy and Hale's brother, a Jesuit priest in New Orleans, were fearful that he had been murdered because of his inside knowledge about the role of the FBI, CIA, and organized crime in events leading up to the Kennedy assassination--knowledge that he had acquired as a member of the Warren Commission and that might also have some relevance to Watergate.
Congresswoman Boggs had expressed her fears to Congressman Bill Hungate as well as to me and Peter Rodino in the strictest confidence.
In 1971 Boggs had made an extraordinary speech on the House floor. The then-majority leader accused the Department of Justice of using "Gestapo-like" police-state tactics that included bugging the offices and homes of members of Congress and other political leaders--and in some cases using illegally obtained information to blackmail public officials.
The unreported truth was that when Boggs made the speech he ws undergoing psychiatric treatment for manic depression, and the CIA and FBI were concerned that his judgement had become sufficiently impaired to endanger national security.Without Honor: The Impeachment of President Nixon And The Crimes of Camelot by Jerry Zeifman
