A classified file released by the FBI shows how the agency tracked Marilyn Monroe's suspected ties to communism in 1956.
The agency documented an anonymous phone call to the New York Daily News that year warning that playwright Arthur Miller was a communist and Monroe had 'drifted into the communist orbit' after her marriage to him earlier that year.
The file is just one piece of the puzzle about what the FBI knew about the actress when she died in August 1962.
The Associated Press waging an ongoing campaign to have more of the FBI documents released by the agency, coinciding with the 50th anniversary Monroe's death.
The caller said Miller's marriage to Monroe during a Jewish ceremony less than a months earlier was a 'coverup.'
Miller, the man said, 'was still a member of the CP (communist party) and was their cultural front man.'
The FBI has long made portions of its documents about Monroe public, but most of them are heavily redacted.
However, the FBI claims it has lost its files on the actress and cannot release them.
Finding out precisely when the records were moved - as the FBI says has happened - required the filing of yet another, still-pending Freedom of Information Act request.
The most recent version of the files is publicly available on the bureau's website, The Vault, which periodically posts FBI records on celebrities, government officials, spies and criminals.
The AP appealed the FBI's continued censorship of its Monroe files, noting the agency has not given 'any legal or factual analysis of the foreseeable harm that might result from the release of the full records.'
Monroe's star power and fears she might be recruited by the Communist Party during the tenure of longtime FBI Director J. Edgar Hoover led to reports being taken on her activities and relationships, including her marriage to playwright Arthur Miller.
Monroe's file begins in 1955 and mostly focuses on her travels and associations, searching for signs of leftist views and possible ties to communism.
There have been two major government investigations into Monroe's demise - the original inquiry immediately after her death and another effort by the Los Angeles District Attorney's Office in 1982.
The second inquiry, released in December 1982, reviewed all files available investigative reports, including files compiled by the FBI on her death. The records, the DA's office noted, were 'heavily censored.'
That mention intrigued the man who performed Monroe's autopsy, Dr. Thomas Noguchi. While the DA investigation concluded he conducted a thorough autopsy, Noguchi has conceded that no one will likely ever know all the details of Monroe's death.
The FBI files and confidential interviews conducted with the actress' friends that have never been made public might help, he wrote in his 1983 memoir 'Coroner.'
