Pietro (Pete) Catucci, 54, a retired D.C. policeman who was employed as a security officer in the office of the Sergeant at Arms of the Senate, died Sunday at his home in Riverdale after a heart attack.

Born in Washington, Mr. Catucci attended McKinley Technical High School and served overseas with the U.S. Merchant Marine during World War II.

He joined the D.C. Police Department in 1945 and retired in 1966 after receiving numerous commendations for meritorious service.

From 1967 until his death, he had worked for the office of the Sergeant at Arms in the Senate.

Mr. Catucci was a past grand knight of the Knights of Columbus, Carroll Council, and a member of the Holy Name Society of Holy Rosary Catholic Church.

He was also a member of the Fraternal Order of Police, the Police Columbia Association, Catholic War Veterans and the Sons of Italy.

Survivors include 10 children, Ernest G., of Chevy Chase, Enrico G., of Hyattsville, Peter G., of Riverdale, Gerard E., of Calverton, Geralyn, of Minneapolis, Minn., and Christine, Angelo J., Kenneth P., Anthony and Finalynn M., all of the home; three brothers, Henry G., Nicholas G. and Angelo J., all of Washington; a sister, Elena C. Gasch, of Wheaton, and seven grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Casa Italiana, 595 3d St. NW, in Washington.
