On a second look through the photos, Charles, I think I found the woman described by Aynesworth. She's right by the entrance to the jail, which is to say, near the south end of the County Records Building along Houston. She is most easily observed in the Betzner photo of the JFK limo on Houston.
To be clear, I don't have a particular grievance against Aynesworth. When I first started researching this case (about 18 years ago), I was confounded by all the cherry-picking and misinformation caused by cherry-picking. So I decided to create a database per se, in which I compared the statements made by witnesses over the years. I started off with the assassination witnesses, but eventually included sections where I compare the statements of the Parkland witnesses as well. And the bottom line is this--most every witness making more than one or two statements over the years contradicted themselves on one point or another.
But that's not to say that witnesses are unreliable. When there is a consistent pattern within the witness statements--such as the earliest and closest witnesses saying the last two shots were bunched together--which is in direct opposition to the cognitive psychology maxim time slows down during traumatic events--one can bet the farm the last two loud sounds heard by the bulk of the witnesses were bunched together.
As far as the possibility of a shot at 190, it's not just the blur analysis and eyewitness evidence that places the first shot at this time, but the photo analysis. One of the most overlooked facts about the case is that the HSCA photography panel concluded a shot rang out before Kennedy went behind the sign...and that they came to this conclusion before the acoustics panel came to their conclusion a shot at Z-190 was probable.
Dave Powers said Kennedy jerked off the side of the car when hit. Kennedy's head and arm movements as he heads behind the sign suggest he was hit at this time. His movements at this time certainly don't look natural. And the failure of Dale Myers etc to acknowledge this and to insist he continued calmly waving at this time is perplexing, to say the least.
