Sylvia Odio was the thirty-year-old daughter of two Cuban refugees who were jailed for the attempted assassination of Fidel Castro. According to Odio’s testimony documented by the Warren Commission, in September of 1963 three men arrived unannounced at Odio’s apartment in Dallas. Two of the three men were of Hispanic descent, possibly Cuban or Mexican. These men identified themselves as “Leopoldo” and “Angelo.” The third man was a slender American who went by the name of “Leon Oswald.”
