JBC's head turn to the right is from z164-171 and follows JFK turning his head in the same direction from z159-168. Neither turns would appear to be unusual. The explanation for those turns was provided by Mary Woodward who said that JFK and Jackie were turned to the left so she waved and shouted to them as they approached. JFK appears to be looking at her as he goes past the lamp post just to the left of Woodward. JBC continues looking and turned to the right as he disappears behind the Stemmons sign. Mary Woodward said that this turn and the subsequent smile and hand wave occurred before the first "horrible, ear-shattering noise". Many others said the same thing. She also said that she and her friends were the last people that JFK ever acknowledged. So that has to be the turn that she is describing.
The turn that JBC described was a turn in response to the first shot, which he recognized as a rifle shot and immediately feared an assassination was taking place. He said he turned to the right to try to see the President. That turn begins about z230. That is the only time he turns around to make any effort to look in the President's direction.
Mary Woodward & friends were on the north side of Elm St, she was 3rd after Millican.
JFK is looking to his right (at Woodward) & then as he disappears behind the sign (Z206) we can see that he has already quickly turned his head hard left
towards an african american family (of dad mum & boy)(on south side of Elm) who appear in Z217.Previous to the african american family on the south side we saw the Willis girl, who has now stopped running (she is last seen in Z223).
That family are the last gawkers on the south side of Elm St (they appear for final time in Z255), until we see Brehm & Brehm boy in Z275, with Beverley Oliver behind Brehm, & then Jean Hill in Z287.
And we know that Oswald's shot-2 was at Z218.
And then when jfk appears from behind the sign (Z225) jfk's head is not turned left nor right.
I am thinking that jfk probly waved to the african american family. In which case they were the last. We dont know their names.
Quote FEDERAL BUREAU OF INVESTIGATION Date: 11/24/63
Mr. JACK FRANZEN, 10572, [sic] Cromwell Circle, telephone FL 7-3717, who is employed by the Fox and Jacob Construction Company, 9106 Soverign [sic] Row, was contacted in response to a telephone call received from him at 1900 Main Street.
Mr. FRANZEN advised he and his wife and small son were standing in the grass area west of Houston Street and south of Elm Street at the time the President's motorcade arrived at that location at approximately 12:30 PM on November 22, 1963. He said he heard the sound of an explosion which appeared to him to come from the President's car and noticed small fragments flying inside the President's car and immediately assumed that someone had tossed a firecracker inside the automobile. He heard a second and third and possibly a fourth explosion and recognized these sounds as being shots fired from some firearm. At the same time he noticed blood appearing at the top and sides of the head of President Kennedy.
He noticed a colored family consisting of a man, woman and small child nearby and at the sound of these shots the man picked up the small boy and ran with the woman west on Elm Street toward the overpass.
During the ensuing confusion he remembers looking at the side of the building occupied by the Texas School Book Depository, located across Elm Street from his position but does not remember seeing anything of a suspicious nature with regard to that building. He noticed the men, who were presumed to be Secret Service Agents, riding in the car directly behind the President's car, unloading from the car, some with firearms in their hands, and noticed police officers and these plain clothesmen [sic] running up the grassy slope across Elm Street from his location and toward a wooded and bushy area located across Elm Street from him.
Because of this activity he presumed the shots which were fired came from the shrubbery or bushes toward which these officers appeared to be running.
He looked over the crowd which had assembled along both sides of Elm Street in this block but noticed nothing which appeared unusual among these spectators.
