It is clear that the note was written while the Oswalds were living in Dallas before they moved to New Orleans in the spring of 1963. The references to house rent and payments for water and gas indicated that the note was written when they were living in a rented apartment; therefore it could not have been written while Marina Oswald was living with the Paines. Moreover, the reference in paragraph 3 to paying “the house rent on the 2d” would be consistent with the period when the Oswalds were living on Neely Street since the apartment was rented on March 3, 1963. Oswald had paid the first month’s rent in advance on March 2, 1963, and the second month’s rent was paid on either April 2 or April 3.[C4-711] The main post office “on Ervay Street” refers to the post office where Oswald rented box 2915 from October 9, 1962, to May 14, 1963.[C4-712] Another statement which limits the time when it could have been written is the reference “you and the baby,” which would indicate that it was probably written before the birth of Oswald’s second child on October 20, 1963. Oswald had apparently mistaken the county jail for the city jail. From Neely Street the Oswalds would have traveled downtown on the Beckley bus, across the Commerce Street viaduct and into downtown Dallas through the Triple Underpass.[C4-713] Either the viaduct or the underpass might have been the “bridge” mentioned in the last paragraph of the note. The county jail is at the corner of Houston and Main Streets “right in the beginning of the city” after one travels through the underpass. _Photographs._--In her testimony before the Commission in February 1964, Marina Oswald stated that when Oswald returned home on the night of the Walker shooting, he told her that he had been planning the attempt for 2 months. He showed her a notebook 3 days later containing photographs of General Walker’s home and a map of the area where the house was located.[C4-714] Although Oswald destroyed the notebook,[C4-715] three photographs found among Oswald’s possessions after the assassination were identified by Marina Oswald as photographs of General Walker’s house.[C4-716] Two of these photographs were taken from the rear of Walker’s house.[C4-717] The Commission confirmed, by comparison with other photographs, that these were, indeed, photographs of the rear of Walker’s house.[C4-718] An examination of the window at the rear of the house, the wall through which the bullet passed, and the fence behind the house indicated that the bullet was fired from a position near the point where one of the photographs was taken.[C4-719]
