This footage is from about 12.50pm.
Therefore! That lady can't be Pauline Sanders
Nor can she be Sarah Stanton, who is admittedly the SPITTING IMAGE OF HER (look at that gray hair-----the match is uncanny!). Heartbreakingly, we know that Sarah reentered the building very shortly after the assassination and didn't leave again until about 14.20
So who could she be??
Logic tells us she's probably either
Vida Lee Whatley or
Virginia H. Barnum.
But logic is boring! Let's pull out all the stops to secure an identification of this random woman who can't possibly be Prayer Person! Go team
