Army Maj. Dale W. Richardson of Mount Sterling, Illinois, will be buried Aug. 29, in Mountain View, Ark. Richardson was assigned to 2nd Battalion, 34th Armor Regiment, 1st Cavalry Division, and was the passenger aboard an UH-1H Iroquois (Huey) helicopter that was en route to Fire Support Base Katum, South Vietnam, when it was diverted due to bad weather. After flying into Cambodian airspace, the aircraft came under heavy enemy ground fire, causing the pilot to make an emergency landing in Kampong Cham Province, Cambodia.
The Huey’s four crewmen and its four passengers survived the landing. One crewman was able to evade being captured by enemy forces and later returned to friendly lines. The other three crewmen and one passenger were captured. Two of the captured crewmen were released by the Vietnamese in 1973, and the remains of the other two captured men were returned to U.S. control in the 1980s and identified. Richardson died at the site of the crash during a fire fight with enemy forces. His remains were not recovered after the fire fight.
From 1992 through 2008, joint U.S. / Kingdom of Cambodia (K.O.C.) teams investigated the site without success. On Feb. 18, 2009, a joint team interviewed witnesses in the Memot District of Cambodia who claimed to have information on the loss. The witnesses identified a possible burial site for the unaccounted for servicemen. The team excavated the burial site but was unsuccessful locating the remains.
From Jan. 16, 2010 to March 11, 2011, joint U.S. / K.O.C. teams excavated the area, but were unsuccessful recovering the crewman’s remains.
In February 2012, another joint U.S. / K.O.C. team re-interviewed two of the witnesses. The witnesses identified a secondary burial site near the previously excavated site. The team excavated the secondary burial site and recovered human remains and military gear from a single grave.
In the identification of Richardson, scientists from DPAA and the Armed Forces DNA Identification Laboratory analyzed circumstantial evidence and used forensic identification tools, to include mitochondrial DNA, which matched his sister.
