Some Tinfoil Hat Conspiracy Theorists believe the first shot missed at Z-160, or so.
Did Rosemary Willis continue running for a full second after hearing "that", or until she heard her father screaming at her and her sister to come back?

"Did Rosemary Willis continue running for a full second after hearing "that"Rosemary told David Lui of the Dallas Time-Herald that she stopped when she heard the 1st shot.
"Around Zapruder frame 160-165, ten-year-old Rosemary Willis, who has been running on the grass alongside the
President's limousine, begins to slow down; by frame 190 she has come to a complete halt. "I stopped when I
heard the shot," she says.(3) "In that first split second, I thought it was a firecracker. But within maybe
one-tenth of a second, I knew it was a gun shot."(4)3. David Lui, "The Little Girl Must Have Heard," Dallas Time-Herald, June 3, 1979, cited in Gerald Posner,
Case Closed (New York: Random House, 1993), p. 321

"or until she heard her father screaming at her and her sister to come back?"Her father said he yelled at both of his daughters after he heard the shots but told the WC they didn't hear him.
Mr. LIEBELER - Did you follow the car down Elm Street after you took the picture, which we have marked Hudson Exhibit No. 1?
Mr. WLLIS - I proceeded down the street and didn't take any other pictures instantly, because the three shots were fired approximately about 2 seconds apart, and
I knew my little daughters were running along beside the Presidential car, and I was immediately concerned about them, and I was screaming for them to come back, and they didn't hear me. But I was concerned about them immediately, because I knew something tragic had happened, and the shots didn't ring out long like a rifle shot that is fired into midair in a distance. I knew it hit something, and it couldn't have been a firecracker or anything like that, so it impressed me, I remember, and after I found my daughters, I saw they were heading back toward their mother.
