Jim Leavelle, the Dallas lawman who was captured in one of history's most iconic photographs, has died at age 99, according to ABC News.
The photograph shows Leavelle, in the light colored suit, escorting President John F. Kennedy's assassin, Lee Harvey Oswald, as he was fatally shot.
Leavelle is seen in the photograph with his hand on Oswald. His reaction is captured as nightclub owner Jack Ruby shot Oswald at close range on live television.
The photo was taken shortly after Kennedy's assassination on November 22, 1963.
Leavelle's daughter Tanya Evers told The Associated Press that her father died Thursday in Colorado.
He had surgery for a broken hip earlier this week and responded well, but later suffered a heart attack.
Leavelle spoke at schools for decades after the assassination, telling his story.
He never believed there were any conspiracy theories regarding JFK's death.
Leavelle has stated that he tried to jerk Oswald behind him to shield him from harm when he saw Jack Ruby approach.
Instead, he simply turned Oswald's body, and the bullet his to the left of his navel instead of dead center.
The photo was taken by Robert H. Jackson, who won a Pulitzer Prize for the image.
