Yung Krall

Yung Krall (Vietnamese: Đặng Mỹ Dung; born 1946) is an American former spy born in Vietnam. Her self-published autobiography, A Thousand Tears Falling, recounts her life growing up in the midst of the Vietnam War, as well as her life in America as a spy for the CIA, FBI, and NSA.

She is the mother of actor and comedian Lance Krall.

Yung Krall was born Đặng Mỹ Dung in 1946 near Cần Thơ in Vietnam during the French administration of the Indochine colony, and lived there during the Anti-French Resistance War. She was nine years old at the signing of the Geneva Conference, which divided Vietnam into North and South Vietnam. Yung's mother chose to remain in South Vietnam to raise her children while her husband joined the Communist cause in the North with the NLF, eventually becoming Hanoi's ambassador to the U.S.S.R.. Krall's father remained in the North for the greater part of her upbringing.

Krall gained employment working for American vendors on a U.S. Navy base near Saigon where she met Lt. John Krall, a U.S. Navy pilot, whom she later married. The two of them moved to the United States.

She worked with the CIA and FBI to recruit informants in the U.S. and Europe and played a role in the arrest and conviction of both David Truong and Ronald Humphrey for passing low-level classified State Department information on to representatives of North Vietnam. Truong was a private citizen of South Vietnam and graduate of Stanford University who opposed U.S. policy in South Vietnam. Humphrey was an employee of the United States Information Service. Neither Truong nor Humphrey were spies for North Vietnam, but acted on their own in a manner they believed could be helpful for reconciliation between the U.S. and Hanoi.
