Beginning in 1976, Pinchot Meyer's life, her relationship with Kennedy, and her murder became the subjects of numerous articles and books, including a full-length biography by journalist Nina Burleigh.

As a child, Pinchot met such left-wing intellectuals as Mabel Dodge, Louis Brandeis, Robert M. La Follette, Sr., and Harold L. Ickes.

[citation needed] Pinchot met Cord Meyer in 1944 when he was a Marine Corps lieutenant who had lost his left eye because of shrapnel injuries received in combat.

That spring they both attended the UN Conference on International Organization in San Francisco, during which the United Nations was founded, Cord as an aide of Harold Stassen and Pinchot as a reporter for a newspaper syndication service.

Their oldest child, Quentin, was born in November 1945, followed by Michael in 1947, after which Pinchot became a homemaker, although she attended classes at the Art Students League of New York.

Meanwhile, her husband began to re-evaluate his notions of world government as members of the Communist Party USA infiltrated the international organizations he had founded.

Their social circle also included CIA-affiliated people such as Richard M. Bissell, Jr., high-ranking counter-intelligence official James Angleton, and Mary and Frank Wisner, Meyer's boss at the CIA.

[citation needed] One of Pinchot Meyer's close friends was a fellow Vassar alumna, Cicely d'Autremont, who married James Angleton.

She also started a close relationship with abstract-minimalist painter Kenneth Noland and became friendly with Robert F. Kennedy, who had purchased his brother's house, Hickory Hill, in 1957.

Nina Burleigh, in her book A Very Private Woman, writes that after the divorce Pinchot Meyer became "a well-bred ingenue out looking for fun and getting in trouble along the way.

"[15] In an interview with Nina Burleigh, Kennedy aide Myer Feldman said, "I think he might have thought more of her than some of the other women and discussed things that were on his mind, not just social gossip."

The unsent letter, written on White House stationery and retained by Kennedy's personal secretary Evelyn Lincoln, sold in June 2016 at auction for just under $89,000.

"[17] On October 12, 1964, Pinchot Meyer finished a painting, then went for her customary daily walk along the Chesapeake and Ohio Canal towpath in Georgetown.

[18] An FBI forensic expert testified at trial that "dark haloes on the skin around both entry wounds suggested they had been fired at close range, possibly point blank".

[5]: 115 [19] The precision, placement and instantaneous lethality of the wounds suggested to the District of Columbia medical examiner that the killer was highly trained in the use of firearms.

[22]: 215 The FBI crime report, withheld from the defense during the trial and published by Peter Janney in his book Mary's Mosaic, documented that there was no forensic evidence linking Crump to the victim or murder scene.

[14] According to Bradlee's account in his memoir A Good Life, moments earlier Janney had heard a radio news report about the murder of a woman at the C&O Canal.

[14] Author Peter Janney, son of Wistar, has established that as of approximately 2:00 pm, when District of Columbia police had Ray Crump in custody at the station, they did not know the identity of the murder victim.

During his trip, he was uncertain as to who had been murdered; he arrived home and noticed the presence of several neighbors, including his close friend Harry "Doc" Dalinsky, a pharmacist.

[11]: 278–81  Roundtree, however, attributed Crump's post-trial violence to the trauma he suffered during his eight-month imprisonment while he awaited trial for Pinchot Meyer's murder.

[22]: 199, 218  Other post-trial revelations appear to corroborate his innocence in the murder, notably the likely presence of another black man at the crime scene and the fact that police dispatched a search for Crump's jacket 15 minutes before his arrest.

In his 1982 autobiography Facing Reality: From World Federalism to the CIA, he wrote, "I was satisfied by the conclusions of the police investigation that Mary had been the victim of a sexually motivated assault by a single individual and that she had been killed in her struggle to escape.

[26] The March 2, 1976, issue of the National Enquirer quoted James Truitt as stating Meyer had a two-year affair with John F. Kennedy and that they smoked marijuana in a White House bedroom.

[13] According to Truitt, their first rendezvous occurred after Meyer was chauffeured to the White House in a limousine driven by a Secret Service agent where she was met by Kennedy and taken to a bedroom.

Truitt said the two would "usually have drinks or dinner alone or sometimes with one of the aides", and claimed that Meyer offered marijuana cigarettes to Kennedy after one such meeting on April 16, 1962.

[14]: 267–68 Ben Bradlee states in his 1995 memoir A Good Life that for several hours after he and his wife Tony learned her sister had been murdered, they were unaware she had kept a diary.

On the night of the murder in their time zone, they received an international phone call from Pinchot Meyer's friend Anne Truitt in Japan.

[14]: 267–68  "The fact that the CIA's most controversial counterintelligence specialist had been caught in the act of breaking and entering, and looking for her diary," Bradlee said, was not something he considered appropriate for public disclosure.

Upon learning years later of the existence, contents and alleged burning of the diary, prosecutor Alfred Hantman and defense attorney Dovey Johnson Roundtree, as well as D.C. Police Detective Bernie Crooke, stated that knowledge of that information at the time of the trial would have materially affected the proceedings.

"[29]: 194 After the 1976 publication of the National Enquirer article on James Truitt's claims, Leary realized Pinchot Meyer had been describing her affair and drug use with President Kennedy.
