Patricia Kennedy Lawford, Sammy Davis, Jr., Marilyn Monroe
In the early 1960's, the FBI was tracking what went on in Jack Kennedy's apartment at the Carlyle Hotel in New York, and in particular, the "sex parties" that occurred there, at least according to Mrs. Jacqueline Hammond.
Some of the participants mentioned in a recently released (under the FOI Act) FBI report include: Frank Sinatra, JFK's younger brothers Bobby and Teddy, Marilyn Monroe, Sammy Davis, Jr., and Mr. and Mrs. Peter Lawford (Mrs. Peter Lawford was JFK's sister Patricia).
