Approximately 1/6th of second after President Kennedy's head was shattered at frame Z-313, Mary Ann Moorman captured a Polaroid photograph (her fifth that day) of the presidential limousine and President Kennedy that also includes the grassy knoll area. What was captured in the background of the photo has been a matter of contentious debate. On the grassy knoll some claim to have identified as many as four different figures, while others dismiss these indistinct images as trees or shadows. - November 19, 2007
