This essay was written in 2021 and is in need of an update. In particular, this memo from FBI SA Alfred Ellington reflects that the official 5/14/63 closing date of P.O. Box 2915 was known to the Dallas Field Office prior to 8:00 a.m. on November 23rd:

I ordered this document from NARA in 2021 but it did not arrive until after I had published the essay. The Mary Ferrell Foundation recently released this record online for the first time as part of their fantastic Dallas Field Office collection:

The significance of the Ellington memo in my opinion is it reflects that the extant application for P.O. Box 2915 is likely genuine, including the closing date stamp. The evidence still overwhelmingly suggests that Marina effectively closed the box on May 10th, but the application itself was stamped on the 14th, either in response to Oswald’s unendorsed forwarding order that arrived on the 14th or the delay from the weekend. I suspect Marina’s control over the box was reflected in internal Post Office records, and she may have assumed control as the primary renter after Oswald went to New Orleans in April ’63. Such a scenario may also explain the “disappearance” of Section 3 of the application.

I have developed other relevant information since 2021, including a tacit admission from Harry Holmes that Ellington was his FBI handler, and that he suspected Marina may have been involved in the rifle purchase. I also discovered a possible explanation for the “Oswald’s mother” confusion based on information provided to the FBI by the CIA. I will post a more detailed addendum at some point, but overall the essay still holds up and contains a lot of interesting evidence you will not find anywhere else.
