Mexico City in early September to receive money and orders for the assassination,567 that he had been flown to a secret airfield somewhere in or near the Yucatan Peninsula,568 that he might have made contacts in Mexico City with a Communist from the United States shortly before the assassination, 569 and that Oswald assassinated the President at the direction of a particular Cuban agent who met with him in the United States and paid him $7,000.570 A letter was received from someone in Cuba alleging the writer had attended a meeting where the assassination had been discussed as part of a plan which would soon include the death of other non-Communist leaders in the Americas.571 The charge was made in a Cuban expatriate publication that in a speech he delivered 5 days after the assassination, while he was under the influence of liquor, Fidel Castro made a slip of the tongue and said, "The first time Oswald was in Cuba," thereby giving away the fact that Oswald had made one or more surreptitious trips to that country.572

Some stories linked the assassination to anti-Castro groups who allegedly were engaged in obtaining illicit firearms in the United States, one such claim being that these groups killed the President as part of a bargain with some illicit organizations who would then supply them with firearms as payment.573 Other rumors placed Oswald in Miami, Fla., at various times, allegedly in pro-Cuban activities there.574 The assassination was claimed to have been carried out by Chinese Communists operating jointly with the Cubans.575 Oswald was also alleged to have met with the Cuban Ambassador in a Mexico City restaurant and to have driven off in the Ambassador's car for a private talk.576 Castro himself, it was alleged, 2 days after the assassination called for the files relating to Oswald's dealings with two members of the Cuban diplomatic mission in the Soviet Union; the inference drawn was that the "dealings" had occurred and had established a secret subversive relationship which continued through Oswald's life.577 Without exception, the rumors and allegations of a conspiratorial contact were shown to be without any factual basis, in some cases the product of mistaken identification.

Illustrative of the attention given to the most serious allegations is the case of "D," a young Latin American secret agent who approached U.S. authorities in Mexico shortly after the assassination and declared that he saw Lee Harvey Oswald receiving $6,500 to kill the President. Among other details, "D" said that at about noon on September 18, waiting to conduct some business at the Cuban consulate, he saw a group of three persons conversing in a patio a few feet away. One was a tall, thin Negro with reddish hair, obviously dyed, who spoke rapidly in both Spanish and English, and another was a man he said was Lee Harvey Oswald. A tall Cuban joined the group momentarily and passed some currency to the Negro. The Negro then allegedly said to Oswald in English, "I want to kill the man." Oswald replied, "You're not man enough, I can do it." The Negro then said in Spanish, "I can't go with you, I have a lot to do." Oswald replied, "The people are waiting for me back there." The
