JPAC's operations were divided into four areas: Analysis and Investigation, Recovery, Identification, and Closure.
Analysis and investigation JPAC investigated leads concerning Americans who were killed in action but were never brought home. This process involved close coordination with other U.S. agencies involved in the POW/MIA issue. JPAC carried out technical negotiations and talks with representatives of foreign governments around the world in order to ensure positive in-country conditions were maintained or created for JPAC investigative and recovery operations wherever JPAC teams deployed in the world. If enough evidence was found, a site was recommended for recovery.
Recovery Nov 6,1998 (July 2004). This particular mission involved searching for the human remains of two
F-4 Phantom crewmen who crashed after a bombing run over Vietnam. JPAC had 18 Recovery Teams whose members traveled throughout the world to recover missing from past wars. A typical recovery team was made up of 10 to 14 people, led by a team leader and a
forensic anthropologist. Other members of the team typically included a team sergeant, linguist, medic, life support technician, forensic photographer, RF systems communications technician/operator and an
explosive ordnance disposal technician. Additional experts were added to the mission as needed, such as mountaineering specialists or divers. The team carefully excavates the site and screens the soil to locate all possible remains and artifacts. In the case of an airplane crash, a recovery site may be quite large. Once the recovery effort was completed, the team returned to Hawaii. All remains and artifacts found during the recovery operation were then transported from a U.S. military plane or private airline to JPAC's Central Identification Laboratory where identification took an average of 18 months; often cited statistics of 11 years include materials that were severely commingled (intentionally) from turnovers from the Korean People's Army in the mid-1990s. These materials only recently began to be identified used several different DNA techniques.
Identification Upon arrival at the laboratory, all remains and artifacts recovered from a site were signed over to the custody of the CIL and stored in a secure area. Forensic anthropologists carefully analyze all remains and artifacts to determine the sex, race, age at death, and stature of the individual. Anthropologists also analyzed trauma caused at or near the time of death and pathological conditions of bone such as arthritis or previous healed breaks. Lab scientists used a variety of techniques to establish the identification of missing Americans, including analysis of skeletal and dental remains, sampling
mitochondrial DNA (mtDNA), and analyzing material evidence, personal effects, aviation life-support equipment (gear used by aircrew: helmets, oxygen masks, harnesses, etc.), or other military equipment. Often, recovered military and personal equipment artifacts were forwarded to the USAF Life Sciences Equipment Laboratory (LSEL, located at Wright-Patterson Air Force Base, in Dayton, OH), for advanced scientific and historical analysis. The LSEL (a highly unique scientific facility within the US and the world) was singularly qualified to scientifically study recovered military equipment artifacts and determine critical forensic aspects, to include, but not limited to: number of unaccounted for personnel represented at the loss site (i.e. 2 aviators), branch of military service represented (i.e. Navy), vehicle type represented (i.e. F-4 aircraft type), time frame represented (i.e. c. 1967), and represented levels of non-survivability or survivability (i.e. any evidence of fatal/non-fatal status). Frequently, the LSEL was able to provide crucial case determinations (through analysis of recovered equipment artifacts) when other critical evidence (such as human remains: bone or teeth) was not recovered or available, and/or does not yield any substantial conclusions through testing (i.e. DNA testing).
Closure The recovery and identification process may take years to complete. The average identification time by the JPAC CIL was 18 months, excluding a vast amount of commingled remains turned over by North Korea, after remains arrived in the laboratory. In addition to the factors previously mentioned, each separate line of evidence was examined at the CIL (bones, teeth, and material evidence) and correlated with all historical evidence. All reports underwent a thorough peer review process that included an external review by independent experts. Additionally, if mtDNA was part of the process, the search for family reference samples for mtDNA comparison added a significant amount of time to the identification process because building a DNA database was not the purview of JPAC. Completed cases were forwarded to the appropriate service
Mortuary Affairs office, whose members personally notified next-of-kin family members. ==Ongoing efforts==
