Warren Commission Hearings, vol. 19, p. 113, Barnes Exhibit A, Right side of Tippit squad car, showing open wing vent window. Mrs. Markham was on the opposite side of the street and a half block back.
By the evening of November 22, five of them (Helen Markham, Barbara Davis, Virginia Davis, Ted Callaway, Sam Guinyard) had identified Oswald in police lineups as the man they saw. A sixth (William Scoggins) did so the next day. Three others (Harold Russell, Pat Patterson, Warren Reynolds) subsequently identified Oswald from a photograph. Two witnesses (Domingo Benavides, William Smith) testified that Oswald resembled the man they had seen. One witness (L.J. Lewis) felt he was too distant from the gunman to make a positive identification.

Specifically, the first report began 1 minute 41 seconds after the 1:16 time stamp. Before that, witness Domingo Benavides could be heard unsuccessfully trying to use Tippit's police radio microphone, beginning at 1:16.[27]
