CIA Memorandum on Gerald Patrick Hemming and Alleged Plot to Assassinate Guatemalan President Laugerud

This CIA internal memorandum, dated 11 June 1976 and authored by Jerry G. Brown (Deputy Chief, Security Analysis Group), documents the Agency's handling of a cable (CIN 944357, dated 8 June 1976) from the Guatemala Station reporting an assassination plot against Guatemalan President Laugerud. According to the cable, a Guatemalan source, with President Laugerud's knowledge, provided a written report and briefing describing a plot originally planned for 15 September 1975. The plot allegedly involved the National Liberation Movement and Jorge Antonio 'Cokie' Zimeri Safie, who left Guatemala in August 1975 after an attack on his life and had since been living in Miami. Zimeri was reportedly linked to two American brothers, Robert and Gerald Patrick Hemming, who assisted in acquiring arms flown to Guatemala. The memo identifies Gerald Patrick Hemming as a notorious mercenary known to the Agency, a long-time associate of Frank Anthony Sturgis (aka Frank Fiorini) of Watergate notoriety, and head of the Intercontinental Penetration Force. It notes President Laugerud's five requests for information about Zimeri and the Hemmings, that the matter was being referred to the FBI and State Department, and references the book 'Coup d'Etat in America' by Michael Canfield and Alan J. Weberman, which attempts to link the CIA to the Kennedy assassination via Howard Hunt, Sturgis, Hemming, and Loran Eugene Hall. The document was released in part with deletions in 1993 and re-released in the 2025 NARA batch.
