Leo J. ‘Skip’ Dunn
CIA official

Leo J. “Skip” Dunn, 85, a retired CIA official who spent more than 40 years at the agency, died May 7 at his home in Potomac.

He had congestive heart failure, his stepdaughter Maria Fusco said.

Mr. Dunn joined the CIA in 1951 as a security clerk and rose to become deputy director of security for policy and management before his official retirement in 1986. He continued working on contract for the agency until 1993.

He had a number of special assignments for the CIA, including work on the Watergate investigation. He spent five years in Asia, including 18 months in South Vietnam in the late 1960s. He also chaired a task force in the 1970s that provided recommendations after Christopher John Boyce and Andrew Daulton Lee were convicted of espionage for selling spy-satellite information to Soviet agents. The case was the subject of a book and film, both called “The Falcon and the Snowman.”

Mr. Dunn received the Intelligence Medal of Merit in 1986 and a certificate of excellence in 1993.

Leo John Dumm was born in Newry, Pa. He changed his name to Dunn after joining the CIA.

He served in the Army in Korea in the 1940s and was a 1951 graduate of St. Francis University in Loretto, Pa. He graduated in 1969 from Georgetown University law school.

Survivors include his wife of 42 years, Uri Julia Ha Dunn of Potomac; their daughter, Julia Kinerk of Scottsdale, Ariz.; two stepchildren, Maria Fusco of Potomac and Richard J. Giroux of Gaithersburg; a brother; and nine grandchildren.
