Acting New Jersey Gov. Kim Guadagno has ordered flags at all state buildings to be flown at half-staff to honor an Army soldier from Palisades Park who went missing in action in Vietnam in 1969.

The flags will be lowered Thursday in tribute to Army Sgt. 1st Class Gunther Wald, whose remains were recently identified. Wald was part of a Special Forces reconnaissance patrol operating near the Vietnam-Laos border in 1969.

The Pentagon says Wald and two other Americans were wounded during an ambush. There were no signs of them when a search-and-rescue team, hampered by the enemy and weather, reached the site eight days later.

A Vietnamese citizen led investigators to human remains he had discovered in 2007. They were excavated in 2010.
