David Atlee Phillips and E. Howard Hunt met and conspired in Guatemala in the 1954 CIA- overthrow of the democratically-elected government of Jacobo Arbenz. Incidentally, Dr. Ernesto "Che" Guevara was there too, observing the whole thing as it unfolded. He later went on to advise Fidel Castro as to how to proceed in Cuba, vis-à-vis the CIA and the politicians in Washington. https://en.wikipedia.org/wiki/David_Atlee_Phillips
In 1961 New Orleans mob boss Carlos Marcello was deported and taken to Guatemala and simply dumped off there despite having no real connection to the country.
