Alan, the 2 people are likely Jarman and Norman who arrived around 12.25. Before they arrived the windows were closed so it is likely that Rowland looked back around the time of the ambulance leaving (12.25).
Agreed. Also, Rowland talks about the black male he sees in the snipers nest (who he describes as 'elderly but also notes " I didn't pay very much attention to him")around the same time (12:15 pm) as he sees the white male with the rifle. The black male is there until the motorcade reaches Main and Elvary which ties in very nicely with Jarman and Norman heading for the fifth after hearing the motorcade is on Main. The 'elderly' black male in the snipers nest at 12:15 must surely be Bonnie Ray Williams. That he is in the snipers nest and up on the 6th floor with a man holding a rifle points to William's heavy involvement in the assassination. This is reflected in the 'extreme inconsistencies' in his various statements, inconsistencies that display a particular pattern.
In his affidavit given on the day of the assassination Williams specifically distances himself from being on the 6th floor. He does not tell the truth about his movements leading up to the assassination (something he is never questioned about):
"We worked up until about 10 minutes to 12. Then we went downstairs. We rode the elevator to the 1st floor and got our lunches. I went back on the 5th floor with a fellow called Hank and Junior, I don't know his last name. Just after we got on the 5th floor we saw the President coming around the corner on Houston from Main Street."It is difficult to imagine this is a 'misrememberance' rather than an outright lie. If it were not for the fact that Bonnie Ray left his lunch on the 6th floor there is a strong chance he would never have been placed there. Once Williams admits he was on the 6th having his lunch he appears embark on a campaign to minimise the time spent there. After each questioning this time gets longer and longer:
22nd November affidavit - is not on 6th floor having lunch
23rd November - tells FBI he stayed on 6th floor for 3 minutes
14th January - Carter and Griffin report Williams went down to 5th floor at 12:05
Warren Commission testimony -
Mr. WILLIAMS. It was after I had left the sixth floor, after I had eaten the chicken sandwich. I finished the chicken sandwich maybe 10 or 15 minutes after 12. I could say approximately what time it was.
Mr. BALL. Approximately what time was it?
Mr. WILLIAMS. Approximately 12:20, maybe.
The evolution of his statements regarding how long it was before he went down to the 5th floor have a specific pattern - 0, 3, 5, 10, 15, 20 minutes. We can synchronise Williams arrival time on the 5th with the statement of Hank Norman to find it is more like 12:29. It can be stated with some confidence Williams is involved in the assassination.
I'm not sure why you have Dougherty using the elevators
after Jarman and Norman. How would he have time to collect stock on the 6th floor and make his way down to the 5th floor in the time allotted by the testimonies. If it's a question of Truly calling the elevator then I think an examination of Truly's actions with Baker might be beneficial.
