In 1963--wearing a white Stetson and a tan suit--Mr. Leavelle was one of the Dallas detectives escorting Lee Harvey Oswald, in the basement of the Dallas Police Headquarters, when Oswald was shot by Jack Ruby. Oswald was handcuffed to Mr. Leavelle, when he was shot.
The remarkable photograph of the shooting--which was awarded a Pulitzer Prize--was taken by Bob Jackson, of the Dallas Times Herald.
Mr. Leavelle died on Thursday; he was 99 years old.
Here is an obituary of Mr. Leavelle, from the New York Times:
The image, below, is of the front page of the New York Daily News, from Monday, November 25, 1963, the day after Oswald's death.
The photograph at the bottom of the Daily News page is the Pulitzer-awarded picture by Bob Jackson. The striking, dramatic picture above it, taken as Ruby approached Oswald, was by Jack Beers, of the Dallas Morning News. Mr. Leavelle is at the left, in each photo.
Both pictures have often been cropped, in varying ways, when seen in newspapers, magazines, books, or on television.
Below, for example, is a much wider view of Bob Jackson's photograph, as seen at the center of the front page of The Scranton Tribune:
