The man seen at the sixth-floor window 4-5 minutes after the assassination by Mrs. Mooneyham may have been Mr. Truly. Or he may have been Mr. Lovelady. Or he may have been Mr. Dougherty. Or he may have been Mr. Oswald. ("I'll keep this cop away from the sixth floor," Mr. Truly mutters to Mr. Oswald by the first-floor storage room, "Get up there and get rid of the damn XYZ.")
This last scenario would actually yield a credible second-floor lunchroom encounter:
----AFTER the encounter at the first-floor small storage room near the front entrance, Mr. Oswald watches Mr. Truly and Officer Baker take off for the shipping floor
----He takes the front stairs up to two and goes through the (empty) office area. His plan is to make his way to the rear stairs in order to go up to six, for he assumes the other two will be already on their way upstairs ahead of him on one of the freight elevators by the time he reaches the rear stairs
----The unexpected use of the stairs by Mr. Truly and Officer Baker leads to Mr. Oswald's being spotted by Officer Baker behind the window of the door leading off the landing
----They have a brief second exchange
----Mr. Oswald ends up taking a freight elevator (the one brought down by Mr. Dougherty?) up to six
Officer Baker doesn't bother mentioning either LHO encounter in his affidavit because he knows this man cannot possibly have been upstairs at the time of the shots.
In the course of the 'investigation', the FIRST LHO-Truly-Baker encounter near the front door is deleted but the SECOND one up at the lunchroom is kept. This allows the ludicrous idea that Mr. Oswald had been on six at the time of the P. Parade to be pushed. It also allows Mr. Truly to explain away the man caught walking away from the stairway several floors up (as per Officer Baker's affidavit).
The attraction of this scenario is that it establishes for the first time a
logical reason for Mr. Oswald to have gone UP to the second floor after the shooting: he was en route to the sixth floor in order to dispose of now undesirable evidence-----------some 'signature' left by the pro-Castro group ostensibly behind the shots-fired incident. (The idea of his going up to two
in order to buy a second Coca-Cola never did wash.*)
*However, he may indeed have purchased a second Coca-Cola in order to cover himself----------in case the officer later talks about meeting him up there. He may even make a point of taking this Coke down to one to be seen by others with it. And---------yes----------he may even go back down to one via the office area, and be seen by Mrs. Reid. Down he goes, back to the first floor, by the front stairs, and makes his way to the rear stairs. Thanks to Mr. Dougherty, a freight elevator is now there for him to take up to six.
