In 1968, Garrigus won a spot on the
United States Olympic Team to compete at the Summer Games held in
Mexico City, and was still a member of the U.S. Air Force Shooting Team. He was the youngest member of the U.S. shooting team at the Games. Garrigus tied for second place in the event, with John Braithwaite of the
United Kingdom winning the
gold medal with a world record score of 198. Held on October 19, the event had a three-way tie for second place between Garrigus, Kurt Czekalla of
East Germany, and Pavel Senichev of the
Soviet Union all with a score of 196. In the first shoot-off between the three competitors, Czekalla and Garrigus had scores of 25 in this event where clay pigeons are shot, while Senichev was eliminated with a score of 22. Garrigus then defeated the East German in the second shoot-off with a score of 25 to 23. This was the highest finish for an American in the event since
Mark Arie won the gold medal in
1920. ==Later life and family==
