Washington (CNN) A Marine who was fatally shot Tuesday at the Marine Barracks in Washington has been identified as Lance Cpl. Riley S. Kuznia, 20, of Karlstad, Minnesota, according to a press release from the Marine Corps on Wednesday.

Kuznia was stationed at the barracks, where he served as a team leader for Guard Company, according to the release.

"We are truly saddened by this terrible loss. Riley was a highly driven and goal-oriented Marine whose positive attitude set the example here at the Barracks," said Col. Don Tomich, commanding officer of Marine Barracks. "Our thoughts and prayers are with Riley's family and friends, and our priority continues to be taking care of them during this tragic time."
