Bernard H. O'Rourke, 60, an official in the office of the adjutant general, Department of the Army, died Tuesday at Fairfax Hospital after apparently suffering a heart attack.

He had been chief of the statistical clearance policy group since 1975.

Born in Chillicothe, Mo., Mr. O'Rourke was a graduate of Chillicothe Business College. He came to Washington in 1940 as a civilian employee of the War Department.

From 1945 to 1947, he was on active duty with the Army and remained in the Army Reserve until retiring as a lieutenant colonel last year.

From 1947 to 1950, Mr. O'Rourke served as a civilian employee in the office of the Army chief of staff for personnel. He then was in the office of the Army comptroller.

Mr. O'Rourke was an active member of the Lake Barcroft Community Association.

He is survived by his wife, Helen Lee O'Rourke, of the home in Lake Barcroft; three sons, Bernard Patrick, of Arlington, Michael Joseph, of Falls Church, and Thomas Hugh, of Leesburg, and four sisters, Thelma Price, of Oregon, Wis., Marjorie Ring, of Wolcott, Conn., Frances Mayta, of Kansas City, Mo., and Betty Bell, of Reno, Nev.

The family suggests that expressions of sympathy may be in the form of contributions to the Dollars for Orphans program of the Downtown Jaycees in Washington.
