Jackson worked for the Dallas Times Herald when he took this photograph.

Jackson studied business in college but later returned to his hobbies of photography and sports car racing. He was the official photographer for the Texas region of the Sports Car Club of America. In 1960 the Dallas Times Herald hired him as a staff photographer. It was while working for this newspaper that he took the picture of Jack Ruby shooting Lee Harvey Oswald. In 1968 Jackson worked for the Denver Post, but he returned to the Times Herald for a time. He later did freelance work before joining the Colorado Springs Gazette. Jackson is now retired.
