On October 13, 1964 the ex-wife of former CIA Covert Action Head Cord Meyer--Mary Pinchot-Meyer--"was shot twice, once in the head and once in the chest with no apparent motive" and she and President Kennedy had been "involved at the time of the president's assassination" on November 22, 1963, acording to The Encyclopedia of American Scandal by George Kohn.
In his book The Senator Must Die, former CIA contract agent Robert Morrow stated that shortly before Mary Pinchot-Meyer was eliminated, he met with a former Deputy Comptroller of the U.S. Treasury, Marshall Diggs, at Paul Young's Restaurant in Washington, D.C. According to Morrow, Diggs told him that Mary Pinchot-Meyer "claimed to my friend that she positively knew that company-affiliated Cuban exiles and the Mafia were responsible for killing John Kennedy." After speaking with Diggs, Morrow "drove to New York and met with [Cuban Exile Leader] Kohly" and "after I told him the story of Mary Meyer, he looked very concerned."
According to Morrow, Kohly then said "Just tell Diggs I'll take care of the matter" and "Then he told me to stay away from him and not tell anyone I had seen him or where he could be found." A week after Morrow's meeting with Kohly in New York, Mary Pinchot-Meyer was, coincidentally, eliminated.
Also, coincidentally, in his 1980 book, Conspiracy, Anthony Summers wrote:
"In 1978 I interviewed the son of the late Mario Kohly...The younger Kohly recalled opening a bottle of champagne at the news of President Kennedy's death and then calling his father. According to Kohly, `My father seemed elated and quite relieved; he seemed more pleased, I would say, than surprised. I am sure he had knowledge of what really happened in Dealey Plaza. But, if you recall, everyone that has had knowledge ended up dead.'"
The same book also observed that Kohly's son quoted the deceased Cuban Exile Leader as saying "John Kennedy was a traitor...He was a Communist."
