On January 21, 1968, Army Sgt. First Class Billy D. Hill, of Wichita, Kansas, was killed in a helicopter that was shot down near Khe Sahn in Vietnam. His remains were not found at the time, and he was declared Missing In Action. Efforts were made, over the years, to find Sgt. Hill and one other soldier who was missing after the same incident, but both soldiers remained missing. In 2014, the remains of unknown soldiers who were found near Khe Sahn and returned in 1989 were analyzed, once again, and DNA matched Sgt. Hill to family members. After almost forty-eight years, Billy D. Hill will be coming home to be laid to rest in Killeen, Texas.
There are still over 1600 missing from the Vietnam War. Here is a link to the Defense POW/MIA website.
