I rule out option 3 altogether. The fourth option would be that Adams descended later than she recalled.
No surprise there, as far as option 3 is concerned. It is, however, still a viable option to be considered if no other plausible explanation is found.
The fourth option is no option at all, as it can be ruled out completely based on the known information.
The building was sealed of by
12.37, so if Adams and Styles came down the stairs after that time, they wouldn't have been able to leave the building
We know from her testimony that Adams was at the front entrance at
12.36, where she heard a radio call and then entered the building. She took the stairs to the 2nd floor, walked through the office space to the freight elevators in the back of the building and saw two men whom she believed were police men or secret agents. She then took the stairs up to the 4th floor. This means that by 12.36 there were already law enforcement people in the building. Had Styles and Adams descended at 12.36 they would most likely have encountered police men running up the stairs, but they didn't
We also know that Adams and Styles left the building at the back, walked around the loading dock and towards the railroad yard. At some point a policeman told them to return to the building and they did so by walking towards Elm street, passing the TSBD and it's warehouse extension at the west side of the building, and turning left on the dead end parallel road in front of the TSBD and walking toward the main entrance, where they arrived at
12.35, as Styles went immediately into the building, which at that time was not yet sealed off.
I would argue that it would have taken the women, on high heels, at least four minutes to walk the distance around the building and have a conversation with the policeman. Working backwards, this would mean that they must have left the building no later than
12.31 which fits perfectly with the scenario of them leaving the window immediately after the shots, running towards the stairs, going down and just missing Truly and Baker.
And then there is this to consider;
Victoria Adams told the FBI on 11/24/63 that she and Styles went down the stairs immediately after the last shot. She said the same thing again to Jim Leavelle on 02/07/64, again to the FBI on 03/23/64 and she repeated it again in her testimony. Dorothy Garner told Barefoot Sanders that the girls went down before Truly and Baker came up. And Sandra Styles told the FBI on 03/19/64 she and Adams left "at that time" after hearing the shots and seeing people running.
Your 4th option basically requires all these statements to be false.
If you don't think these statements are false, we can rule out option 4 all together, which basically leaves us, to reach agreement, options 1 and 2
1. The encounter never happened and Adams remembered something that never took place.
2. The girls crossed paths with Shelley and Lovelady at the parking lot and Adams only parcially remembered
Right?
