Retired Air Force Col. Frank P. Dunnington Jr. died Tuesday of heart disease at his home on Indian Head Road in Ruxton.
Colonel Dunnington, who was 83, retired in 1965 as head of the Air Force Office of Special Investigations for District 12, which handled counterintelligence work in Illinois, Indiana and Missouri. He joined the Office of Special Investigations during the Korean War. His career started in 1939 in the Army's Judge Advocate General's Corps.
During World War II, he was the inspector general for Army Air Forces units in England and then for the 82nd Airborne Division during its campaigns in Europe. At the end of the war, he was chief of war crimes investigations for the 9th Army, a job that involved work at several concentration camps. Later, he became an officer in the newly formed Air Force.
His decorations included the Bronze Star.
Born in White Hall, he was a graduate of the Polytechnic Institute, the University of Virginia and the University of Maryland law school.
He was survived by several cousins.
