Status:
Unknown
Discussion:
SEQUIN was described in a CIA report in around September of 1954 as an administrative coordinator. A cable on 23 January, 1954, mentioned that the U.S. State Department had reported the previous day that SECANT (Major Enrique Trinidad Oliva) was under arrest and SEQUIN's house had been searched by Guatemalan police. A telegram on 31 January, 1954, stated that SEQUIN was known by Delgado (probably Jorge Isaac) and SECANT. A report on Operation PBSUCCESS in around November of 1954 mentioned that SEQUIN fled to El Salvador early in February 1954, after the White Paper expose, and resumed his operations from that country. A cable on 28 May, 1954, stated that SEQUIN could be identified as a SYNCARP (the "Junta", Castillo Armas' political organization headed by Cordova Cerna) representative. A dispatch on 4 June, 1954, mentioned that Licenciado Luis Coronado Lira of F.A.G.E. was SEQUIN's general assistant, who along with Alberto Molino Menocal, were the two people that SEQUIN relied on the most. A dispatch on 12 June, 1954, stated that two of SEQUIN's contacts in El Salvador included Minister of Interior, Lemus, and Salvadoran Ambassador to Honduras, Adolfo Rubio Melhado. Both were former classmates of Carlos Castillo Armas' at an air force school in the U.S. Another contact of SEQUIN's was Manuel Diaz Sal, Captain of Ilopango Airport. A cable on 26 June, 1954, mentioned that SEQUIN had advised that communications between himself and Castillo Armas had been handled in the past by Jorge Isaac Delgado, a Costa Rican national resident of Nicaragua, who piloted a small plane and travelled between Central American countries. SEQUIN's pseudonym was apparently Ingeniero Viniteco.

Circa 09/01/54: Index of De-briefing Reports: Pages 80-81: ANNEX F: TACTICAL INTELLIGENCE AND GENERAL by Withheld..."According to information which had been supplied by Calligeris (Carlos Castillo Armas), the entire intelligence organization within the target area was being run by SEQUIN, with the aid of SEMANTIC and SECANT (Major Enrique Trinidad Oliva). A closer study of the situation revealed, however, a picture that was somewhat different. SEQUIN's position at that time could be better defined as that of an administrative coordinator, not entirely responsible for intelligence, but also responsible for coordinating efforts along the PP and PM lines in the target area. SEQUIN's main contribution in the intelligence field was his handling of SLEEKER through SETTLER. The SLEEKER/SETTLER complex had been producing fairly well at that time, but it was felt that much of their production could have been obtained through overt sources...The three key Calligeris men in the target, SEMANTIC, SECANT and SEQUIN, all performed a multiplicity of functions. This not only had an adverse effect on security as far as compartmentation was concerned, but also created serious problems during the last few months of the operations, when the size and diversity of the jobs to be performed made it a humanly impossible task for these three men-and finally only SEMANTIC and SECANT - to be responsible for accomplishing the major part of the task which lay ahead..."
