May 1, 1962 - Two U.S. Army sergeants captured by the Viet Cong more than three weeks ago were freed today by their captors. The Communists turned them loose five miles from the spot where they were seized April 8. The sergeants said they had suffered no brutal treatment at the hands of the Viet Cong, although their wrists had been kept bound. They did not know why they had been set free. They were simply told they could go. For 22 days, Sgts. Francis Quinn of Niagara Falls, N.Y., and George E. Groom of St. Joseph, Mo., were held in a peasant hut on a mountain behind Danang, northeast of Saigon. Following their release today, they were brought in a cargo plane to Saigon where they were interrogated by officers of the special U.S. force in Vietnam.
