James - After Darnell filmed that segment showing the retaining wall, Elm St, etc, he then filmed the interview of Sitzman there at the Pergola Shelter. After that, Darnell filmed those "3 girls" walking down the knoll below the Pergola. Richard Trask's "Pictures Of The Pain" did not provide a timeline for this film segment. I realized that these same "3 Girls" were also filmed by Tina Towner at the very end of her film. (I can't be sure, but it looks like the same 3 Girls). Trask time stamped this Towner film "3 Girls" segment to be at, "About 10 minutes" after the shooting. This same Towner segment showing the "3 Girls", also shows a man running down from the Pergola shelter area. He begins to circle around in front of the girls. This man might be Darnell getting into position to film his own segment of these same 3 girls. It's a rough estimate, but figure around 12:40 for the Darnell film segment you asked about.
Dear Royell,
Those three young women -- self-described American Indian Stella Mae Jacob, strawberry-blond Gloria Jeanne Holt, and blue-headscarf-wearing Sharon Simmons -- still(?) mislabeled in the Zapruder film as "Gloria Calvery," "Karan Hicks," and "Carol Reed," respectively, by the likes of Don Roberdeau and Robin Unger, were filmed walking across the concrete "patio" on the Grassy Knoll several minutes after the assassination NOT by Tina Towner, but by Tina Towner's father, Mr. Towner, with Tina Towner's camera.
You really should improve the quality of your so-called "JFKA research," Royell.
