From Cuban counterintelligence officer Fabian Escalante's book "The Cuba Files", pg. 130-132.
"Guillermo Ruiz was the translator in the conversation between Azcue and Oswald. He told Fabian Escalante that although he was not an expert in physiognomy, it was his opinion that the Oswald he saw on Mexican television was the one he saw in the consulate that day. Antonio Garcia Lara [who worked in the trade office at the Consulate] saw Oswald as he was leaving, and he had the same impression as Ruiz. Both of them disagreed with Azcue."
So we have two additional witnesses saying that they believed the man who visited the Cuban consulate *was* Oswald. Four in all: Mirabal, Duran, Ruiz and Garcia Lara. A problem with these later accounts, of course, is that Azcue never mentioned the two men, particularly Ruiz who supposedly helped translate for him. And Duran never mentioned them either. Very odd.
Again, the Cubans concluded it *was* Oswald who visited their consulate but they argue he was sent there by someone or some group - CIA or anti-Castro groups - to connect the assassination through him to Havana. Conspiracy believers gonna' conspiracy argue no matter what is presented.
