I believe big, tall, glasses-wearing Gloria Calvery was one of the four headscarf-wearing gals who were standing virtually shoulder-to-shoulder on the north side of Elm Street during the motorcade in the Zapruder film.
I believe that she can be seen about 30 seconds after the final shot in the Couch-Darnell clip as she's standing on the TSBD steps (with her back to the camera), evidently talking with a baldish man (Joe Molina?) as a youngish dressed-in-white woman (Calvary's colleague, Carol Reed or Karan Hicks?) passes her on the right and apparently tries to coax her up the steps.
I believe we can see at the same time one of her motorcade-watching colleagues (Carol Reed or Karan Hicks) running like crazy from left-to-right down Elm Street Extension towards the TSBD entrance, Officer Baker dashing from left-to-right towards the front steps, Roy Truly spinning around in front of the steps, watching Baker run past him, and Billy Lovelady and William Shelley booking it down Elm Street Extension towards the railroad yard / parking lot.
Assuming I'm right, does what I've said have a bearing on 1) the veracity of Lovelady's and Shelley's claims as to what they did after the assassination (and how soon), 2) the accuracy of the statements of Officer Baker, Roy Truly, Vicki Adams, and Sandra Styles, and 3) whether or not it was possible for Oswald to descend from the 6th floor to the 2nd floor lunchroom without being seen by any of those last four people?
Regarding Molina, this is what he told the Warren Commission:
Mr. BALL. Do you know a girl named Gloria Calvary (sic)?
Mr. MOLINA. Yes.
Mr. BALL. Did Gloria come up?
Ms. MOLINA. Yes, she came. I was in the lobby standing there and she came in with this other girl.
Mr. BALL. What did she say?
Mr. MOLINA. She said “Oh, my God, Joe, he’s been shot.” They were both horrified. I said “Are you sure he was shot?” She said “Oh, Joe, I’m sure. I saw his hair fly up and I’m sure he was shot,” something to that extent.
. . . . . . .
I figure Molina mis-remembered exactly where he was when Calvery and her colleague encountered him on the steps, and that the three of them probably went into the building and continued their conversation there.
