By far the most important confirmation of Senora Duran's testimony, however, has been supplied by confidential sources of extremely high reliability available to the United States in Mexico. The information from these sources establishes that her testimony was truthful and accurate in all material respects. The identities of these sources cannot be disclosed without destroying their future usefulness to the United States.

The investigation of the Commission has produced considerable testimonial and documentary evidence establishing the precise time of Oswald's journey, his means of transportation, the hotel at which he stayed in Mexico City, and a restaurant at which he often ate. All known persons whom Oswald may have met while in Mexico, including passengers on the buses he rode, 552 and the employees and guests of the hotel where he stayed,553 were interviewed. No credible witness has been located who saw Oswald with any unidentified person while in Mexico City; to the contrary, he was observed traveling alone to and from Mexico City, 554 at his hotel, 555 and at the nearby restaurant where he frequently ate.556 A hotel guest stated that on one occasion he sat down at a table with Oswald at the restaurant because no empty table was available, but that neither spoke to the other because of the language barrier.557 Two Australian girls who saw Oswald on the bus to Mexico City relate that he occupied a seat next to a man who has been identified as Albert Osborne, an elderly itinerant preacher.558 Osborne denies that Oswald was beside him on the bus.559 To the other passengers on the bus it appeared that Osborne and Oswald had not previously met, 560 and extensive investigation of Osborne has revealed no further contact between him and Oswald. Osborne's responses to Federal investigators on matters unrelated to Oswald have proved inconsistent and unreliable, and, therefore, based on the contrary evidence and Osborne's lack of reliability, the Commission has attached no credence to his denial that Oswald was beside him on the bus. Investigation of his background and activities, however, disclose no basis for suspecting him of any involvement in the assassination.561

Investigation of the hotel at which Oswald stayed has failed to uncover any evidence that the hotel is unusual in any way that could relate to Oswald's visit. It is not especially popular among Cubans, and there is no indication that it is used as a meeting place for extremist or revolutionary organizations.562 Investigation of other guests of the hotel who were there when Oswald was has failed to uncover anything creating suspicion.563 Oswald's notebook which he carried with him to Mexico City contained the telephone number of the Cuban Air- lines Office in Mexico City; 564 however, a Cuban visa is required by Mexican authorities before an individual may enplane for Cuba,565 and a confidential check of the Cuban Airlines Office uncovered no evidence that Oswald visited their offices while in the city.566

Allegations of conspiracy.--Literally dozens of allegations of a conspiratorial contact between Oswald and agents of the Cuban Government have been investigated by the Commission. Among the claims made were allegations that Oswald had made a previous trip to
