ICMP, EAAF, and ICTY Recovery Protocols

Clyde Snow arrived in Argentina in 1984 at the invitation of the newly democratic government's National Commission on the Disappearance of Persons. He brought with him the methods of American forensic anthropology, developed primarily in homicide investigations, and applied them to the scale problem of thousands of disappeared individuals buried in clandestine graves across the country. He trained a cohort of archaeology and anthropology students who formed EAAF, and the team began excavating graves in 1984.

EAAF's methodological innovation was systematic: archaeological excavation of the burial, osteological analysis in a laboratory setting, ante-mortem data collection from family interviews, and careful comparison. Before EAAF, exhumations in conflict contexts were often rapid and politically directed, producing identifications through face recognition or clothing that were subsequently challenged or wrong. EAAF insisted on the scientific standard: an identification required convergent lines of skeletal, dental, and eventually genetic evidence. The team also insisted on independence from the state, working under agreements that kept its forensic conclusions outside political control.

The team's emphasis on family liaison was as important as its technical contribution. Families of the disappeared were brought into the process, told how identification worked and what to expect, and given formal notification when an identification was made. This model, treating families as stakeholders with rights rather than as passive subjects, became the standard for subsequent international operations including ICMP's Bosnia programme.

The ICTY, established in 1993, faced a problem EAAF had not: the forensic teams were working not only to identify the dead for families, but to produce evidence that would support criminal prosecutions of named defendants. This dual function required a more formal evidence-management framework than the identification programmes EAAF had pioneered. The Office of the Prosecutor commissioned forensic teams, primarily under the direction of forensic anthropologist William Haglund and pathologist John Clark, to conduct exhumations at sites across Bosnia-Herzegovina and Croatia.

The approach combined archaeological excavation with forensic pathology. Each individual was excavated in situ, photographed, given a unique body-bag number linked to a GPS-recorded location, and transferred to a mortuary where pathological examination established cause of death and where osteological analysis recorded age, sex, stature, and trauma. The full documentation package for each individual became a legal exhibit in the relevant case file.

The Rule 94bis procedure required that defence teams receive expert reports in advance and could request cross-examination. This meant forensic team members had to be prepared to defend their methods, qualifications, and conclusions under adversarial challenge. In practice this sharpened methodological discipline: investigators documented their reasoning explicitly, distinguished between findings and inferences, and were careful not to overstate what the physical evidence could support.

The International Commission on Missing Persons was announced at the G7 Lyon summit in June 1996, with an initial mandate to address the estimated 30,000 missing persons from the conflicts in Bosnia, Croatia, and Kosovo. It established its headquarters in Sarajevo and initially focused on coordinating the work of national commissions on missing persons. By the late 1990s it had become clear that the scale of the identification problem in Bosnia alone required a DNA-based approach.

ICMP built a laboratory network and a reference database of family DNA samples. Relatives of missing individuals donated blood samples from which STR profiles were generated. Post-mortem bone samples from excavated graves were processed in parallel. Matching was performed by a proprietary database system that compared post-mortem profiles against the family reference database and flagged probabilistic matches above a threshold, which were then reviewed by a geneticist before a report was issued to the relevant national commission. The report, when confirmed, initiated the official identification process and the return of remains to families.

• Over 7,000 Srebrenica-related identifications completed by 2023, representing approximately 87 percent of the estimated victim population.
• Reference database holds over 90,000 family profiles from former Yugoslavia alone.
• Bone sample processing developed for highly degraded material: powdered cortical bone, inhibitor-removal protocols, mini-STR amplification.
• ICMP identification reports used as evidence in ICTY and MICT proceedings and in national courts across the region.

ICMP's mandate has since expanded globally. It has assisted with missing persons programmes in Colombia, Mexico, Libya, Iraq, and elsewhere, and played a role in the identification of victims of the 2004 Indian Ocean tsunami. The organisation's legal basis was consolidated when it became a formal intergovernmental organisation under international law in 2014, giving it legal personality similar to that of other international bodies.

The INTERPOL DVI (Disaster Victim Identification) framework was developed for mass casualty events such as aircraft crashes, distinguishing it from single-victim homicide investigation. Its core structure is the AM/PM process: ante-mortem data describing the missing person (medical records, dental charts, physical descriptions, photographs, DNA reference samples) is assembled independently of post-mortem data gathered from remains, and the two are compared in a reconciliation step. A confirmed identification requires the convergence of at least one primary identifier (dental comparison, fingerprint, or DNA) or multiple secondary identifiers.

In conflict-related mass casualty contexts, the AM data source is often family testimony rather than pre-existing medical records, because victims were healthy adults in a country without comprehensive dental records. EAAF, ICMP, and the ICTY commissions all developed family interview protocols that extracted maximum physical description data while being sensitive to the trauma of the interview process. Questions covered clothing worn at last sighting, healed injuries, jewellery, and identifying features. These descriptions became the ante-mortem record against which recovered clothing and skeletal trauma were compared.

The Minnesota Protocol, formally the UN Manual on the Effective Prevention and Investigation of Extra-Legal, Arbitrary, and Summary Executions, was first published in 1991 and substantially revised in 2016 under the auspices of the UN Special Rapporteur on extrajudicial, summary or arbitrary executions and the Office of the United Nations High Commissioner for Human Rights (OHCHR). It is not a treaty but a document of normative authority: states party to the International Covenant on Civil and Political Rights (ICCPR) are bound to investigate potentially unlawful deaths, and the Protocol provides the minimum technical and procedural content of an adequate investigation.

For forensic practitioners the Protocol's most operational provisions concern exhumations. It requires that the legal basis for exhumation be established before work begins, that a chain of custody be maintained from first exposure of remains through laboratory analysis, that family members be informed and consulted, and that the investigation be conducted by appropriately qualified personnel independent of the authorities suspected of involvement. These are not aspirational standards: courts have cited failures to meet them as evidence that an investigation was inadequate.

• Legal authority for exhumation must be established in advance; consent or court order is required.
• Chain of custody documentation from first exposure of remains to final laboratory disposition.
• Investigators must be qualified and independent of suspected parties.
• Families must be informed, consulted, and given the opportunity to observe or participate.
• Unidentified remains must not be disposed of until all reasonable identification efforts are exhausted.

One of the most operationally significant contributions of the ICTY and ICMP experience was the formalisation of body-bag numbering as a chain-of-custody tool. Each set of remains recovered from a grave receives a unique identifier that links it to: the specific grave site, the spatial position within the grave (recorded by total-station or GPS), the date of recovery, the body bag itself, the post-mortem examination record, any DNA samples taken, and the ultimate identification decision or open case record. This cascade of linkages means that at any point in the process, a bone sample or clothing exhibit can be traced back to its exact position in the ground and forward to any court record in which it appears as evidence.

ICMP developed a parallel AM numbering system so that a family's blood reference sample could be linked through a pseudonymous code to both the family interview record and the post-mortem DNA profile without exposing identifying information to laboratory staff performing the matching. This privacy protection was important for securing family participation and complied with applicable data protection requirements. The pseudonymous architecture did not prevent full traceability; it simply required an authorised reconciliation step before personal identification data was released.
