put out at night to be shined. The scheme progressed as far as procuring the chemical and testing it on animals. [deletion] recollection is that Castro did not make the intended trip, and the scheme fell through. [deletion] remembers consideration being given to use the thallium salts (perhaps against Castro) and something having to do with boots or shoes. [deletion] does not remember with whom he dealt on this plot. We found no one else with firm knowledge of it.
Gambling Syndicate:
The first seriously pursued CIA plan to assassinate Castro had its inception in August 1960. It involved the use of members of the criminal underworld with contacts inside Cuba. The operation had two phases: the first ran from August 1960 until late April or early May 1961, when it was called off following the Bay of Pigs; the second ran from April 1962 until February 1963 and was merely a revival of the first phase which had been inactive since about May 1961.
Gambling Syndicate – Phase I
August 1960
Richard Bissell, Deputy Director for Plans, asked Sheffield Edwards, Director of Security, if Edwards could establish contact with the U.S. gambling syndicate that was active in Cuba. The objective clearly was the assassination of Castro although Edwards claims that there was a studied avoidance of the term in his conversation with Bissell. Bissell recalls that the idea originated with J. C. King, then Chief of WH Division, although King now recalls having had only limited knowledge of such a plan and at a much later date – about mid-1962.
Edwards consulted Robert A. Maheu, a private investigator who had done sensitive work for the Agency, to see if Maheu had any underworld contacts. Maheu was once a special agent of the FBI. He opened a private office in Washington in 1956. The late Robert Cunningham, of the Office of Security (and also a former Special Agent with the FBI), knew Maheu and knew that his business was having a shaky start financially. Cunningham arranged to subsidize Maheu to the extent of $500 per month. Within six months Maheu was doing so well financially that he suggested that the retainer be discontinued. Over the years he has been intimately involved in providing support for some of the Agency’s more sensitive operations. He has since moved his personal headquarters to Los Angeles but retains a Washington office. A more detailed account of Maheu’s background appears in a separate section of this report [...]
Maheu acknowledged that he had a contact who might furnish access to the criminal underworld, but Maheu was most reluctant to allow himself to be involved in such an assignment. He agreed to participate only after being pressed by Edwards to do so. Maheu identified his contact as one Johnny Roselli, who lived in Los Angeles and had the concession for the ice-making machines on “the strip” in Las Vegas and whom Maheu understood to be a member of the syndicate. Maheu was known to Roselli as a man who had a number of large business organizations as clients. Edwards and Maheu agreed that Maheu would approach Roselli as the representative of businessmen with interests in Cuba who saw the elimination of Castro as the essential first step to the recovery of their investments. Maheu was authorized to tell Roselli that his “clients” were willing to pay $150,000 for Castro’s removal.
September 1960
Shef Edwards named as his case officer for the operation James P. O’Connell (a former Special Agent of the FBI), then Chief, Operational Support Division, Office of Security. O’Connell and Maheu met Roselli in New York City on 14 September 1960 where Maheu made the pitch. Roselli initially was also reluctant to become involved, but finally agreed to introduce Maheu to “Sam Gold” who either had or could arrange contacts with syndicate elements in Cuba who might handle the job. Roselli said he had no interest in being paid for his participation and believed that “Gold” would feel the same way. A memorandum for the
