ROYAL OAK, Mich. — The U.S. Army is searching for the family of a Michigan man killed in the Vietnam War who will be honored at a memorial in May.

The Daily Tribune reports that Robert Townsend was 29 when he was fatally shot in 1965 in South Vietnam while a sergeant with the Army Security Agency.

The National Security Agency plans to honor Townsend at the Memorial Wall in Fort Meade, Maryland.

The Intelligence and Security Command’s History Department has asked Lonnie Long and Gary Blackburn to look for Townsend’s family. Long and Blackburn wrote a book about the Army Security Agency and Vietnam.

Long says Townsend joined the army after graduating from Royal Oak High School in 1954. Townsend married Mary Edwards, with whom he had three children.
