Serendipitously segueing this thread into what I've posted on another one ("Why Did The First Shot Miss?"), I've just now stumbled upon the FBI's 11/25/63
report regarding the observations of
Mrs A. G. (Jane) Berry that says she was standing (with her colleague Betty Thornton
on Elm Street in front of the TSBD, according to her 4/01/64 statement to the FBI) "
just west of the building," and that
as the limo was passing her, she heard the first of three shots ring out.
Which, if she was standing near the tip of the "island" or at the very base of Elm Street, would appear to jibe with what Amos Euins and Patricia Ann Lawrence (married name Donaldson) say in the excellent video,
The Lost Bullet -- that the first shot ran out right after the limo had passed the black-and-white "Highway 80" signs on the "island".
