History and Scope of Forensic Archaeology

The British Army Graves Registration Units that operated in France and Belgium from 1914 onward were not archaeologists in any academic sense, but their practice anticipated forensic archaeology in several important ways. They worked from maps and aerial photographs to locate probable burial sites. They used systematic probing to confirm sub-surface remains before excavating. They recorded each find with sufficient detail to support identification, and they maintained documentation chains that allowed families to be notified years after the war ended. The scale was extraordinary: the Imperial War Graves Commission eventually registered over 587,000 graves, with hundreds of thousands more commemorated as missing.

The Second World War produced equivalent operations and added new complexity. Crash-site archaeology for downed aircraft required the same kind of controlled excavation that would later be used in criminal investigations, and pathologists and anthropologists were often present at recoveries. In some cases the work was done under conditions that required chain-of-custody documentation, particularly for war-crimes investigations that were already being contemplated by the Allied powers before the war ended.

The gap between this kind of practical work and a recognized academic discipline persisted for decades. Police searches for murder victims were typically conducted without archaeological input, and the evidentiary value of the site itself, as distinct from the body it contained, was poorly understood by investigators. It was not until forensic scientists and academic archaeologists began collaborating in the UK from the late 1970s onward that the discipline started to acquire a professional identity.

Eric Pye is among the figures most closely associated with the systematisation of forensic archaeological practice in the UK. Working at the interface of police casework and academic archaeology, Pye developed and documented protocols for police searches and grave excavations that could withstand scrutiny in criminal courts. His contributions were methodological and institutional: establishing that archaeologists could operate within chain-of-custody requirements and that their findings could be presented as expert testimony.

The name of Keith Simpson is sometimes associated with the early use of expert evidence in homicide cases involving buried remains, though Simpson was primarily a pathologist. His casework during the mid-twentieth century underscored the limitations of relying on pathological examination alone when a grave had been disturbed or when the context of the burial contained forensically significant information. These limitations were part of the pressure that eventually brought archaeologists into the field.

The Archaeology and Forensic Science group, and later the AGSA, gave practitioners a forum for developing shared standards, reviewing each other's work, and establishing training pathways. This institutional scaffolding mattered because forensic archaeology was (and in many jurisdictions still is) a small discipline with no standardized accreditation, where the quality of practice varied significantly between practitioners. Professional bodies provided the peer-review mechanism that courts need when evaluating expert evidence.

Forensic archaeology, forensic anthropology, and crime-scene investigation are distinct disciplines with distinct site roles. Conflating them in court can undermine the admissibility or weight of evidence, particularly if an archaeologist is asked to give opinions that fall within the expertise of an anthropologist, or vice versa.

In practice these boundaries are more permeable than the table suggests. At a mass grave, the archaeologist directing the excavation may also have anthropological training and may make in-field observations about trauma or skeletal preservation. What distinguishes the professional is not the absence of overlapping skills but the clarity about which judgements fall within their primary expertise and which require a specialist.

Argentina's military dictatorship between 1976 and 1983 caused the disappearance of at least 8,961 people, the figure documented by CONADEP in its Nunca Mas report, with credible estimates considerably higher. When democratic government returned, families of the disappeared faced the task of identifying remains from clandestine graves across the country within a judicial system that had no established framework for this kind of physical evidence. The EAAF, founded in 1984 with the support of physical anthropologist Clyde Snow, was created to address that gap.

What made EAAF significant beyond Argentina was the operational model it established: a politically independent scientific team working within a judicial framework, using archaeological field methods and anthropological laboratory analysis to produce evidence capable of supporting prosecutions. The team maintained scientific standards in a politically charged environment and documented their methods transparently enough to be scrutinised and replicated elsewhere. That combination established EAAF as a reference point for subsequent human-rights recovery operations.

The EAAF model influenced teams in Guatemala (FAFG), El Salvador, Chile, Spain, and eventually Bosnia and Kosovo. It also influenced the protocols adopted by international tribunals. When the ICTY began excavating graves at Srebrenica from 1996, the methodological inheritance from Argentine practice was direct and explicit.

The International Criminal Tribunal for the former Yugoslavia opened its first investigations in the mid-1990s and faced a problem without precedent at that scale: thousands of missing persons, with remains distributed across primary and secondary graves that had been deliberately relocated to complicate investigation. The ICTY drew on experts from several countries, developed detailed protocols for mass-grave excavation, and produced an evidentiary record that had no precedent in the discipline.

The Srebrenica investigations produced several technical developments that became standard practice. The concept of primary and secondary graves, in which a perpetrator disturbs an original mass burial and moves remains to a more remote location, became central to the archaeological interpretation of the evidence. Establishing the relationship between primary and secondary graves required integrating archaeological, geological, and DNA evidence across three disciplines. The ICTY cases also generated detailed legal rulings on the admissibility of archaeological evidence and the standards required of expert witnesses.

The ICC, established by the Rome Statute in 2002, extended the operating context for forensic archaeology. Unlike the ICTY, which addressed a specific conflict, the ICC is a standing court with jurisdiction over genocide, crimes against humanity, and war crimes committed anywhere in the world. Forensic archaeology is now a routine component of ICC investigations across Africa, Asia, and elsewhere, requiring practitioners to operate in a wider range of environments, legal systems, and security situations than those in which the discipline originally developed.

In England and Wales, forensic archaeologists work most frequently as contractors to police forces investigating homicides, suspicious deaths, and missing-person cases involving potential burial. They are engaged when a scene requires systematic ground search or when a grave must be excavated in a way that preserves contextual evidence. The Senior Investigating Officer holds legal responsibility for the investigation; the archaeologist controls the physical recovery and recording within that structure.

• National criminal investigations: police forces in England, Wales, Scotland, Northern Ireland, and across Europe engage forensic archaeologists for homicide, terrorism, and missing-persons cases where ground search or grave excavation is required.
• Disaster victim identification: aviation crashes, building collapses, and floods generate scenes that require systematic archaeological recovery methods even though the cause is not criminal. The discipline contributes to DVI operations alongside pathology and odontology.
• Human-rights investigations: NGOs including EAAF, Physicians for Human Rights, and the Guatemalan FAFG deploy archaeologists to recover evidence of atrocities, often decades after the events, in contexts where no state authority is either able or willing to do the work.
• International tribunal support: the ICTY, ICC, and ad hoc special courts have all used forensic archaeologists as both investigators and expert witnesses. The ICMP in Bosnia has produced the most sustained institutional example of archaeological methods applied at scale to a post-conflict identification programme.
• Teaching and research: a growing number of universities in the UK, USA, Australia, and Europe offer forensic archaeology programmes. Research focuses on improving search methods, validating geophysical techniques, and developing quality-assurance frameworks for casework.
