Resolution of small-scale commingling: a case report from the Vietnam War.
A case is reported that involves the commingled skeletal remains of two individuals who died in a helicopter crash in 1969 during the Vietnam War. The incomplete portions of two bodies were initially recovered soon after the crash. These portions were identified by personnel at a U.S. Army Mortuary in Saigon and were returned to the next-of-kin. While searching for scrap metal in 2002, a Vietnamese citizen unexpectedly discovered human remains and personal effects interspersed with buried aircraft wreckage. The personal effects correlated with the individuals who died in the 1969 incident. These newly discovered remains and artifacts were subsequently received at the U.S. Army Central Identification Laboratory, Hawaii (CILHI) for analysis. As part of the CILHI analysis it was necessary to segregate the commingled remains into specific individuals for identification purposes. Details regarding various sorting techniques are described that provide a solid framework for systematically dealing with small-scale commingling. The sorting techniques used in the resolution of this case consist of visual pair-matching, articulation, process of elimination, osteometric comparison, and taphonomy. These techniques, when used in conjunction with each other, provided a solid basis for the individualization of most skeletal elements.
