A 19-year-old Army sergeant from Gallup, New Mexico, killed in the Korean War in 1953 has been identified through DNA testing and buried this week after 73 years as a missing person. Sgt. Celestino Chavez Jr. was among remains returned by North Korea following the 2018 Trump-Kim summit and was posthumously awarded a Silver Star for holding his defensive position despite wounds. The case exemplifies decades-long efforts by the Defense POW/MIA Accounting Agency to identify fallen servicemembers and return them to families — a process that has accelerated in recent years through DNA advances.
