Original 35mm black and white negative taken by Dallas Times Herald staff photographer John Mazziotta. This image shows a Secret Service agent outside the emergency entrance to Parkland Hospital. Behind him is a white car with lights on the roof and a corner of the presidential limousine. In the background, a crowd waits for news. The images on this negative strip were taken by Dallas Times Herald staff photographer John Mazziotta at Parkland Hospital that day. There were two Dallas Times Herald photographers at Parkland - Eamon Kennedy and John Mazziotta. Bob Jackson, another photographer who was at Parkland earlier, was not at the hospital when the Johnsons left, as is pictured in the last frame on the strip.
