CIA Memorandum on Gerald Patrick Hemming and Guatemalan Assassination Plot (1976)
This eight-page file reproduces a CIA Office of Security memorandum dated 11 June 1976 from Jerry G. Brown, Deputy Chief of the Security Analysis Group, to the Chief of the Security Analysis Group, together with JFK Assassination System identification forms. The memo reports that a Guatemala Station cable (IN 944357, Cite Guatemala City 19536, dated 8 June 1976) relayed a Guatemalan source's account — known to President Laugerud — of a plot to assassinate the Guatemalan president. The plot, said to have been planned for 15 September 1975, involved the National Liberation Movement and Jorge Antonio 'Cokie' Zimeri Safie, who reportedly fled Guatemala in August 1975 after an attempt on his life and had since lived in Miami. Zimeri was said to be tied to two American brothers, Robert and Gerald Patrick Hemming, who allegedly helped acquire arms flown to Guatemala. The memo profiles Hemming as a notorious mercenary and soldier of fortune, long-time cohort of Frank Anthony Sturgis (aka Frank Fiorini) of Watergate notoriety, both former U.S. Marines who briefly joined Fidel Castro before founding anti-communist mercenary groups (the International Anti-Communist Brigade and the Intercontinental Penetration Force). It notes attempts by authors Michael Canfield and Alan J. Weberman, in their 1976 book 'Coup d'Etat in America,' to link the CIA to the JFK assassination through Hunt, Sturgis, Hemming, and Loran Eugene Hall, and recalls New Orleans DA Jim Garrison's 1967 allegations. The document notes CIA denies Hemming ever had genuine Agency affiliation despite his repeated claims. The file was released with deletions by NARA on 18 March 2025.

From the name, physical description, activity, and alleged employment, it is apparent that Gerald Patrick HEMMING is identical with the subject of Office of Security file 429 229, who has been described as six-foot five, 250 pounds, who is a notorious mercenary and soldier of fortune and who as of May 1975 was ostensibly employed by a private investigation company, TEPCOL Security (Office of Security--no record) in Miami, Florida. NW 89804 Docld:323605651 Page 3 ~ 8. Gerald Patrick HEMMING is well known to this Agency, the Office of Security Miami Field Office, and JNWAVE. On numerous occasions since at least the early 1960's, HEMMING had claimed Agency affiliation when in fact there has been none. The most recent incident wherein HEMMING claimed such affiliation was in May 1975 when he volunteered his services to the Drug Enforcement Administration. Gerald Patrick HEMMING is a long-time cohort of Frank Anthony STURGIS (SF#353 459), aka: Fréenk FIORINI, of Watergate notoriety who also has a long-time record of falsely claiming Agency affiliation. In the late 1250's HEMMING and STURGIS, both former U.S. Marines, joined Fidel CASTRO in Cuba but returned shortly thereafter Claiming disillusicnment with the CASTRO cause. Soon thereafter, STURGIS organized a group of mercenaries for Caribbean and Central American activities which he named the International er Anti-Communist Brigade. A reported sub-unit of this "Brigade" (the backers of whom have never been fully established) was named the Intercontinental Penetration Force, headed by Gerald Patrick HEMMING. 9. For an appreciation of the possible ramifications of a Guatemalen government expose of this assassination plot involving HEMMING, you are referred to attachments to instant memorandum, to wit: a memorandum by the writer dated 10 June 1975 in the name of Frank STURGIS and Everett Howard HUNT, Jr.; and an extract from a book published in early 1976 written by Michael CANFIELD and Alan J. WEBERMAN. The book Coup d'etat in America--The CIA and the Assassination of John F. Kennedy Is a diatribe against the Agency and attempts to link the Agency with the assassination _of President KENNEDY. One of the major _ links attempted by the authors is through Everett Howard HUNT, Jr. to Frank STURGIS to Gerald Patrick HEMMING to Loran Eugene HALL. Loran Eugene HALL was a member of HEMMING's Interconti- nental Penetration Force. Loran Eugene HALL received nationwide publicity in 1967 when New Orleans District Attorney “Jim GARRISON alleged that HALL (and the Intercontinental Penetration Force) was involved in the assassination of President KENNEDY and that members of this unit were connected with CIA. GARRISON shortly thereafter dropped his interest in HALL, but it is interesting. that he did so after Gerald Patrick HEMMING and another cohort, Robert K. BROWN, joined GARRISCN's investigation.
