Discussion:
Trigon is defined as "an archaic term for triangle". AMTRIGON-2 was probably Roberto Herrera (aka Tico Herrera). AMTRIGON-8 was Miguel de los Santos Delgado Martinez. Both A-2 and A-8 were part of the crew of the Villaro vessel. A dispatch in October of 1962 stated that AMOT-28 (Andres Eugenio Venegas Garcia) reported in late September that the brother of AMTORRID-1 had told the former that AMTRIGON-1 was organizing a group or association called the Hermandad Cubana (Cuban Brotherhood), which included about seven or eight Americans. The dispatch added that AMTRIGON-1 lived "with two Americans at 220 N.W. 8th Avenue, top floor, Miami. In the upper room #5 of this house the group has arms and equipment." One of AMTRIGON-1's associates was said to have been a man named "Larry" (possibly Larry Laborde/AMDENIM-4). The dispatch also noted that "AMTRIGON-1 doesn't try to hide his anti-American feelings, and he says he doesn't want to have anything to do with KUBARK (CIA) personnel." According to Fabian Escalante, former Cuban intelligence chief, in his book, JFK: The Cuban Files, on November 13, 1963, "Argimiro Fonseca Fernandez, Wilfredo Alfonso Ibanez, Israel Rodriguez Lima, and Erasmo Manchin Garcia, four CIA agents infiltrated into Cuba for subversive and espionage activities, were captured and brought to trial. Guns, pistols, ammunition, and letters written in invisible ink were taken from them. The CIA had given them the task of locating coastal areas suitable for landing arms." Andres Venegas is discussed in the strange epilogue to the Bayo-Pawley mission, where much disinformation is contained about survivors - see 104-10057-10102 - page 6. Venegas was AMOT-28.
