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.

file. When "Dan" contacted the writer, "Dan" advised that he
is the action officer for a cable from the Guatemala Station
reporting an assassination plot on the life of President _
LAUGERUD of Guatemala. "Dan" was unfamiliar with the case of
Gerald Patrick HENMING and had not as yet reviewed the 201 file
on HEMMING. "Dan" was requested to alert CI Staff and JMWAVE

copy of the report..coming in from the Guatemala Station.

Er.

2. ‘Dan'' provided the writer with a copy of the cable
(IN 944357, Cite Guatemala City 19536, dated 8 June 1976),
which is attached. In substance, the cable reflects that
circa 8 June 1976 a Guatemalan source, with the knowledge of

Guatemalan President LAUGERUD, provided the Guatemala Station

-—--- -g written report, and.a detailed briefing, concerning a-plot

to assassinate President LAUGERUD. According to the informa-
tion the plot was to have been carried out on 15 September
1975; however, one of the major conspirators, Jorge Antonio
"Cokie" ZIMERI Safie left Guatemala in August 1975 as a result
of an attack upon his, ZIMERI's, life. ZIMERI has been Tiving
in Miami since August 1975S.

NOTE: The Guatemala Station also included
information the Chief of Station had received
from ESDEW-1 on 8 June. ESDEW-1 said that he
had been providing information on ZIMERI to the
Guatemalan government for the past six months or  _
so. He claimed that two Americans were involved
with ZIMERI, one of them who runs a guard service
in Miami. ESDEW-1 did not mention names but ,
described one of the Americans as about six feet
four inches and weighing about 230 pounds.

b. In the event ZIMERI is not in the United
States legally, deport him to Guatemala.

c. Is ZIMERI recruiting merceraries in the
United States for possible use in
Guatemala?

d. Does ZIMERI receive any kind of preferen-
tial treatment by U. S. authorities which
permit him to carry firearms, as well as’
to purchase arms and ammunition for

5. On 19 June 1976 "Dan" of the Guatemala Desk advised
that DDO is referring the entire matter to the FBI and State
Department. ~

6. Office of Security indices are negative in pertinent
variations of the name of ZIMERI or Robert HEMMING.

7. 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.
