As Special Agent In Charge Jerry Parr quickly pushed Reagan into the limousine, the fourth bullet hit Secret Service agent Timothy McCarthy in the abdomen as he spread his body over Reagan to protect him. The fifth bullet hit the bullet-resistant glass of the window on the open side door of the limousine. The sixth and final bullet ricocheted off the armored side of the limousine and hit the president in his left underarm, grazing a rib and lodging in his lung, stopping nearly 1 inch (25mm) from his heart. Parr's prompt reaction saved Reagan from being hit in the head. Reagan suffered from a punctured lung and heavy internal bleeding. He received medical attention quickly.
