Marilyn Monroe

Patricia Seaton Lawford, the fourth wife of actor Peter Lawford, also deals with the Monroe-Kennedy matters in her 1988 biography of Peter Lawford, entitled The Peter Lawford Story. Lawford's first wife was Patricia Kennedy Lawford, a sister of John and Robert; Lawford was very close to the Kennedy family for over a decade, including the time of Monroe's death.
In 1997, documents purporting to prove a coverup of a relationship between JFK and Monroe were discovered to be fraudulent.
