I was shooting as they were coming along, and Jacqueline and the President were waving, and as {the car] came in line with my camera, I heard a shot. I saw the President lean over to Jacqueline - I didn't realize what had happened, actually - then the second shot came. I saw his head open up, and I started yelling, "They killed him, they killed him!" and I continued shooting until they were under the underpass. (from a 1966 interview)
