 As documented by the House Select Committee on Assassinations, this fifth photo was captured concurrent with Zapruder film frame 202.In his fifth photo, some conspiracists allege that the image of a still-unknown person can be seen located up on the grassy knoll, seen near a 3-foot-tall concrete wall and near the 5-foot-tall stockade fence.The angled shape of this still-unknown person's outline has led to that person's image being labeled by authors in books and persons working in the Kennedy assassination research community the "black dog man."
