11/23/63 cable MEXI-7021 from Easby/White to Director: "(FBI) agent left here 2000 local with two copies each of six photos person suspected (to) be Oswald (note: The "Mystery Man") on special flight to Dallas. He carrying envelope with one copy each photo for airmail special from Dallas for Galbond/JC King at home as per telecon with Curtis. 1 copy each (of) these photos showing same person exiting (Cuban) Embassy forwarded in HMMA 22533 (see 104-10422-10254, pp. 2-3) leaving regular pouch tonight.
"Alan White, who was Deputy Chief of Station in Mexico City in 1963, testified that Ann Goodpasture was a 'Special Assistant' to the Chief of Station and that 'her main responsibilities were to handle the surveillance operations..."
"The description of Oswald is marked on (DIR 74830, see 104-10125-10249, p. 2) with a double black line, a check mark, and the description '24 years old' in Ann Goodpasture's hand-writing. At this point, at least Ms. Goodpasture and Allen White, the DCOS, realized that the photograph they had described in MEXI 6453 (see 104-10428-10260, p. 2) was not of Oswald. But this realization was evidently not shared by all the officers in the station...Ms. Goodpasture remembers she believed, based on the cable, that the photograph reported in MEXI-6453 was not Oswald.

Endnote 45: Warren Commission staffers David Slawson and William Coleman admitted in a 2003 interview that White was the one who actually played the Oswald tape for them in Mexico City during April 1964: This admission was made in interviews conducted by the authors Gus Russo and Stephen Moulton, recounted in Brothers in Arms (New York, Bloomsbury, 2008), p. 312. Endnote 47: Under penalty of perjury, Alan White and several other CIA officers denied that an Oswald tape existed after 11/22/63, but John Whitten's testimony was that "I think so...tapes were probably still in existence". See 124-10230-10434: FBI agent Bert Turner also asked the Mexico City office to send to him "tapes previously reviewed in Dallas".
