I have recently read most of the book “The Girl on the Stairs” by Barry Ernest. And here’s a quote from that book that helped clarify for me an aspect of Victoria Adams’ testimony about what she saw and heard when the shots were fired:
“I specifically asked if she remembered seeing Kennedy when she heard the first shot. “No,” she answered, “because I did not see the limousine at that time. It was under the tree.” As she gazed out the window, she said, the tree was “slightly to my right.””
Ernest’s book gives me the impression that Victoria Adams was a credible witness. But Victoria’s WC testimony left it a little unclear to me whether the first shot was fired just before JFK disappeared beneath the tree or just after he disappeared under the tree. The clarification, in Ernest’s book, inspired me to use my 3-D computer model to try to determine at approximately what point in time (z-frame) JFK would have disappeared from her view because of the tree.
I placed a generic tree in a position that corresponds with the tree’s position indicated on Don Roberdeaux’s map. I placed the 3-D virtual visitor’s view at the fourth floor window that Victoria testified that she watched the motorcade from. I already had a convertible with a male character sitting in the right rear seat placed in the position of JFK at Z-133, according to Don’s map. And it is apparent that JFK is hidden from the view by the tree from that window at the z-133 point in time.
I know that there are a few others here that have created their own 3-D computer models of Dealey Plaza. And if any one of them can help me verify my results with a similar experiment of their own, I would greatly appreciate it.
Anyone with a copy of Don’s map can simply place a straightedge between that window and the Z-133 mark indicated on Elm Street and see for themselves that it crosses the edge of the tree limbs. However, seeing it on a 3-D computer model helps to verify what it looks like from that elevation and location.
