13. Although in his interrogation on Friday afternoon, November 22, Oswald said he was having lunch on the first floor of the Book Depository Building at the time of the assassination, during Sunday’s interrogation Oswald slipped up and placed himself on the sixth floor at the time of the assassination, making him the only employee of the Book Depository Building who placed himself on the sixth floor, or was placed there by anyone else, at the time we know an assassin shot Kennedy from the sixth floor. In his Sunday-morning interrogation he said that at lunchtime, one of the “Negro” employees invited him to eat lunch with him and he declined, saying, “You go on down and send the elevator back up and I will join you in a few minutes.” He said before he could finish whatever he was doing, the commotion surrounding the assassination took place and when he “went downstairs,” a policeman questioned him as to his identification, and his boss stated that he was one of their employees. The latter confrontation, of course, refers to Officer Marrion Baker, in Roy Truly’s presence, talking to Oswald in the second-floor lunchroom within two minutes after the shooting. Where was Oswald at the time the Negro employee invited him to lunch, and before he descended to the second-floor lunchroom? The sixth floor. Charles Givens testified that around 11:55 a.m., he went up to the sixth floor to get his jacket with cigarettes in it and saw Oswald on the sixth floor. He said to Oswald, “Boy, are you going downstairs…it’s near lunchtime.” He said Oswald answered, “No, sir. When you get downstairs, close the gate to the elevator.” There is another very powerful reason why we can know that Oswald, at the time of his confrontation with Baker in the second-floor lunchroom, had just come down from the sixth floor, not up from the first floor, as he claimed. It is an accepted part of conspiracy dogma to believe what Oswald told Fritz during his interrogation—that he had been eating lunch in the lunchroom on the first floor at the time of the shooting and had walked up to the second floor to get a Coke from the Coke machine just before Baker called out to him.
