INTRODUCTION
It is usual when reviewing a particular subject in a particular locality to begin with a definition and
summary of practice. Consideration of forensic archaeology in Brazil, however, requires some
understanding of Brazilian history in relation to this important – but neglected – area of knowledge,
and how it is located in the context of contemporary Brazilian society. Importantly, forensic
archaeology in Brazil has been closely intertwined with the development of forensic anthropology,
although contributions from more traditional archaeological thought and practice have become a
more recent feature.
This chapter therefore begins with a brief overview of Brazil’s somewhat hectic past and some key
developments in legislation that have led to the rather incongruous state of forensic archaeology in a
country whose economy is ranked the world’s sixth largest and which has been chosen to host
major sporting events such as the FIFA World Cup in 2014 and the Olympic Games in 2016.
Discussion of the contemporary situation in forensic archaeology in Brazil then follows, with
reference to illustrative examples.
Brief Historical Background
The significance of recent history to forensic science and medicine in Brazil has been considered by
Guimarães (2003) and Soares and Guimarães (2008). Brazil began as a Portuguese colony in AD
1500. Europeans initially subjugated indigenous peoples and subsequently imported slaves from
Africa. Coexistence led to intense admixture between these populations. After independence in
1822, Brazil became an imperial monarchy that had only two emperors – Dom Pedro I and II. In
1888, Brazil was the last country in the world to abolish slavery, and in 1889 it became a republic.
In the 20th
century, from 1930-1945, the country had its first period of dictatorship under the control
of Getúlio Vargas. A new wave of migration followed, composed mainly of World War II refugees
from Japan, Italy, Germany, and Eastern Europe, but with others from the Middle East, leading to a

further period of considerable admixture and intermarriage. In 1964, another dictatorship was
established. Leftist political parties were banned and civil rights limited. This dictatorship lasted
until 1985 – making advanced democracy a recent acquisition for Brazil.
The criminal law is defined robustly in the Brazilian Penal Code (Brasil 1940) and Brazilian Penal
Process Code (Brasil 1941), both of which were established during the Vargas dictatorship and
which have received only minor modification since. These codes specify that all forensic
investigations are the responsibility of the Civil Police (Polícia Civil). Although this arrangement is
not entirely without merit, the resulting degree of governmental control made investigations
vulnerable to political manipulation, both during the Vargas years and again during the military
dictatorship of 1964-1985. As a consequence of this legislation, research and teaching in all
branches of the forensic sciences were badly affected. Forensic cases were kept away from the
Universities, which were considered centres of political subversion. Very poor conditions of work
in forensic medicine became the rule, as did the lack of up-to-date technology for criminal
investigation. In many important respects, human identification was one of the worst-affected areas.
Keeping victims unidentified meant that government institutions could avoid being the target of
criticism or investigation. Political crimes could be hidden and members of the political opposition
– mainly from left-wing political parties – could be ‘disappeared’ (Guimarães 2003, 215).
Within the vast 8,515,767 km2 of the Brazilian interior (IBGE 2010), however, it was not an easy
task for the military government to keep all opposition groups under control. Armed resistance
spread to the countryside, and both urban and rural guerrilla networks developed. While
confrontations resulted in deaths sustained by both sides, it was the military government that was
accused of continuous human rights violations – through exile, torture, execution and the
‘disappearance’ of political prisoners.
Eventually, gradual liberalisation led to the Amnesty Law (Brasil 1979), enabling the exoneration
of some Brazilian citizens who had been convicted of political crimes between 1961 and 1979.
While the military dictatorship finally ended in 1985 with the indirect election of a civilian

president, it was the establishment of the New Constitution (Brasil 1988) that was ultimately the
most significant step in the process of re-democratization and restoration of civil and human rights.
The Amnesty Law (Brasil 2002) was also amended, enabling exoneration of those convicted of
political crimes committed between 1946 and 1988.
Restorative actions on behalf of victims also formed part of the re-democratization process. The
Special Commission for the Political Dead and Disappeared (Comissão Especial de Mortos e
Desaparecidos Políticos (CEMDP)), was the first formal government initiative in the investigation
of the political crimes of the dictatorship (Brasil 1995). This was followed by the establishment of
the office of the National Secretary for Human Rights (Secretaria Nacional dos Direitos Humanos
(SNDH)) (Brasil 1997) – both within the Ministry of Justice. The SNDH was later elevated to
Ministry status (Brasil 2003) and the CEMDP was incorporated within its structure (Brasil 2004). In
2010, the SNDH was further elevated to become part of the President’s Office and its name
amended to the Secretary of Human Rights of the President of the Republic (Secretaria de Direitos
Humanos da Presidência da República (SDH/PR)) (Brasil 2010). The main contemporary national
initiatives in the use of forensic archaeology and anthropology in the investigation of alleged human
rights violations in Brazil are linked to SDH/PR-CEMDP.
In 2011 the President, Dilma Rousseff, herself a former political prisoner of the military
government, signed into law the establishment of the National Commission of Truth (Commisão
Nacional da Verdade) (Brasil 2011a), mandated to investigate human rights violations occurring
between 1946 and 1988. Under the auspices of this Commission, independent investigations are to
be undertaken which are intended to bring to light the widest possible range of findings relating to
human rights violations in the country. The Commission’s work is to be completed by 2014.
ACADEMIC, PROFESSIONAL AND LEGAL ASPECTS

According to Zarankin and Funari (2008, 310), archaeology in the Americas has traditionally
focused on the study of prehistoric societies and their lifestyles, dietary habits, and economic
activities. In the public imagination, however, there is a gap between the exotic and distant past that
archaeologists analyse and the present world. Frequently, it was the Indiana Jones representation of
the archaeologist that was used to fill this gap.
This situation began to change when, some years ago, archaeologists began to question the nature of
the knowledge they produced, and its wider social consequences. Archaeology became a political
tool for opening new lines of inquiry regarding marginal groups in history – slaves, women,
children, gays, lesbians, workers, aboriginals, prisoners, the elderly and afro-descendants – whose
importance is now more widely accepted. It was believed that this critical discussion of past
domination, exploitation, and resistance would lead archaeologists to political action in the present.
It was thought that the democratic potential of archaeology could be co-opted in order to create
alternative histories for invisible, minority, and oppressed groups (Zarankin and Funari 2008, 310).
In this context, it is not surprising that academic archaeology only began to expand in the last years
of the military government, when steps toward democracy had already occurred.
Perhaps the most significant development in academic archaeology in Brazil occurred in 1980 with
the creation of the Society for Brazilian Archaeology (Sociedade de Arqueologia Brasileira (SAB)),
which had its first scientific meeting in 1981 at the Universidade Estácio de Sá in Rio de Janeiro.
This University offered a unique undergraduate degree in archaeology at that time – although
archaeology courses were sometimes delivered elsewhere from various Departments of
Anthropology, Geography and History. Although this particular archaeology degree did not survive
past the beginning of the last decade (SAB 2013) there are today 11 undergraduate courses at public
institutions in Brazil – the first of which was established in 2004. Six of these are at specialisation
level and, additionally, there are 14 Masters and six PhD programs (Costa 2013).
Given the historic absence of dedicated undergraduate degree courses in archaeology, many
professionals who work in the field have a degree in a related area such as social science, history,
Guimarães, M.A., Francisco, R.A., de Abreu e Souza, R. and Evison, M.P. (2015) Forensic archaeology and anthropology in Brazil. In Groen, M., Márquez-Grant, N. and Janaway, R. (eds.), Forensic archaeology: current trends and future prospects. New York: Wiley. ISBN 978-1-118-74598-4
geography, biology or geology. The SAB accepts affiliation of members who do not have a degree
in archaeology, but in an alternative specialisation, Masters or PhD degree and, occasionally, those
with formal experience working in the area for at least five years. Most work in Brazil, however, is
still focused on academic research in prehistoric and historical archaeology, preservation of the
national historical and cultural heritage and, recently, in assessments for construction engineering
where potential archaeological sites need to be investigated before building work commences.
Forensic Archaeology
Although it is clear that archaeological techniques are sometimes essential in criminal investigation,
the role of the archaeologist in the forensic arena is still very limited in Brazil. There are two main
reasons for this.
The first reason is related to the above-mentioned legislation that controls forensic investigation in
Brazil. The Brazilian Penal Code (Brasil 1940) and the Brazilian Penal Process Code (Brasil 1941)
– both from the Getúlio Vargas dictatorship – limit forensic investigation of crimes to ‘official
experts’ who are police staff. However, occasionally a non-official expert can be appointed by the
police or judicial authorities to participate in a forensic investigation as an ad hoc expert — a
geophysicist or some other academically qualified professional, for example. The legislation
predates the arrival of professionals with a degree in archaeology, however, and there is no legal
requirement for police forces to recruit or appoint archaeologists to apply their skills in criminal
cases. Archaeologists can apply along with other graduates to join the police service with the aim of
becoming an ‘official expert’, but even if selected there is no guarantee they will be deployed to
work in their specific area of interest. There are, simply, no official posts for archaeologists on
police staff to work in forensic archaeology.
The second reason is related to specialisations in qualifications. Among the 11 undergraduate
courses in archaeology mentioned above, only two offer formal content in forensic archaeology.
One is compulsory – a 30 hour module with the Universidade do Estado do Amazonas. The other is
Guimarães, M.A., Francisco, R.A., de Abreu e Souza, R. and Evison, M.P. (2015) Forensic archaeology and anthropology in Brazil. In Groen, M., Márquez-Grant, N. and Janaway, R. (eds.), Forensic archaeology: current trends and future prospects. New York: Wiley. ISBN 978-1-118-74598-4
optional – a 60 hour module with the Universidade Federal de Sergipe. It is possible that other
courses are offered in private institutions, but these do not typically serve potential professionals.
There are as yet no standards for the qualification and experience of University teachers in forensic
science, curriculum content or the methods of theoretical and practical instruction used.
A final point to be considered is that death certificates relating to violent deaths can only be signed
by medical doctors who are also ‘official experts’ – the equivalent of the forensic pathologist in
some jurisdictions, limiting the role of the professional forensic archaeologist and anthropologist in
the forensic investigation of human remains.
The overall consequence is that archaeologists are not typically seen as the most suitable
professionals to work in forensic cases. This very limiting vision is the result of the late origin and
lack of a tradition of archaeology as an academic or professional occupation in the country.
Changes in this perception have been marked by the publication of Arqueologia: Direito e
Democracia [Archaeology: Law and Democracy] (Carvalho et al. 2009) and Memories from
Darkness: Archaeology of Repression and Resistance in Latin America (Funari et al. 2010). Both
books highlight the importance of forensic archaeology in the investigation of human rights
violations that occurred during the dictatorship years in Brazil and Latin America. These are
probably the most relevant texts to the application of archaeology in the interests of the courts in
Brazil, a field still considered to be at an ‘embryonic stage’ by one of the authors.
Technical contributions on bioarchaeology, biological anthropology and forensic anthropology have
been produced by the archaeology team from the National School of Public Health of the Oswaldo
Cruz Foundation – as described by Mendonça de Souza (2009). Bioarchaeologists have contributed
sporadically to forensic science and medicine, having delivered courses to the Police Academy of
São Paulo in 2006 (Silva e Oliveira 2009, 171) and participated in the recent foundation of the
Associação Brasileira de Antropologia Forense in September 2012 (ABRAF 2012).
Forensic Anthropology
Guimarães, M.A., Francisco, R.A., de Abreu e Souza, R. and Evison, M.P. (2015) Forensic archaeology and anthropology in Brazil. In Groen, M., Márquez-Grant, N. and Janaway, R. (eds.), Forensic archaeology: current trends and future prospects. New York: Wiley. ISBN 978-1-118-74598-4
Forensic Anthropology is a relatively new area of science, having originated during the 20th
century
(Burns 1999). It applies methods from physical anthropology and archaeology in the collection and
analysis of evidence related to apparent crimes, with the aim of establishing the identity of the
victim and the circumstances relating to the individual’s death (Soares and Guimarães 2008, 7;
Francisco et al. 2011, 231).
Despite – or, perhaps, because of – its relevance to criminal justice, the development of forensic
anthropology was also badly affected in the years of dictatorship in Brazil. It was not convenient for
government institutions involved in political repression and the violation of human rights – like
torture and homicide – to have a well-established infrastructure for forensic anthropology, which
could make such abuses public knowledge. During the military dictatorship, the bodies of political
prisoners who died in the large urban centres were autopsied, as required by law, but the death
certificate was liable to be modified to disguise the real cause of death. This practice was sometimes
condoned or supported by the official medical expert, some of whom supported the dictatorship. If
not, the medical examiners concerned could find themselves harassed into changing the final
diagnosis, or substituted by other experts willing to cooperate with the deception. Probably the most
widely known case of this type concerned the journalist Vladimir Herzog, who died after his arrest
in 1975. His body was found in a prison cell in a military institution in São Paulo City. The official
cause of death was given as ‘mechanical asphyxia by hanging’. Suicide was inferred even though
signs of torture were evident on his body. It was not until March 13th
2013 when, as a consequence
of a judicial application on behalf of the National Commission of Truth and the Herzog family, the
cause of death recorded on the death certificate was corrected to include ‘lesions and maltreatment’
while in the custody of the II Army DOI-CODI (Borges 2013).
Again, it is not surprising that forensic anthropology, like forensic archaeology, could only emerge
after the end of the dictatorship in 1985 and the establishment of the New Constitution, when the
first groups in Brazil – such as those located in Campinas (São Paulo State) and Brasília (the
Brazilian capital) – began to establish expertise. The forensic anthropology group in the Department

of Legal Medicine at the Universidade de Campinas (UNICAMP) was founded in 1986, and
worked on cases of national importance, such as the identification of the remains of the Nazi doctor
Josef Mengele. The Department was dissolved in 1999 for academic reasons mainly related to
limited scientific productivity, but specialist expertise is retained by the School of Odontology
located at the Piracicaba campus of the University. The second group, linked to the Medico Legal
Institute of the Secretariat of Public Security in Brasilia, is part of the civil police structure. It was
established in 1992 on the initiative of three official experts – Drs. Malthus Galvão, Eduardo Reis
and Aluísio Trindade Filho – who recognised the necessity for expertise the area. It is significant
that it was individual, rather than government, initiatives that led to the establishment of this
expertise. The group now has six members and deals with routine cases from Brasília and
surrounding areas. This group has also worked on cases of national importance, such as the
investigation of GOL flight 1907 (CENIPA 2008) and participates in the search for remains of
victims of the military dictatorship as part of the Araguaía Working Group (Grupo de Trabalho
Araguaia) (see below).
Other groups have since arisen around the country, including – among others – in Salvador (Bahia
State), Goiânia (Goiás State), Rio de Janeiro (Rio de Janeiro State), Porto Alegre (Rio Grande do
Sul State) and Recife (Pernambuco State). Most of these are linked to police institutions, except for
the one in Recife, which offers a postgraduate course (a Masters in Forensic Expertise) including a
module in forensic anthropology.
In Ribeirão Preto, a city in the interior of the State of São Paulo, a significant change arose in 1996,
when post-dictatorial changes in legislation in the State allowed the establishment of partnerships
between public institutions. Originally conceived by Dr. Carmen Martin, the Centro de Medicina
Legal (CEMEL) was established in the city in 1999 as the result of a partnership between the
Faculty of Medicine of Ribeirão Preto - University of São Paulo (FMRP-USP) and the Medico
Legal Institute – Secretary of Public Security of São Paulo (IML/SSP-SP). CEMEL became the first
centre in Brazil to bring officially recognized forensic expertise into the University sector. This

partnership offers better facilities and a higher quality scientific environment for forensic experts,
and access to forensic data for teaching and research in the University – something unimaginable
during dictatorship years (Guimarães 2003, 215). Expertise was extended to include forensic DNA
profiling of skeletal remains via collaboration with the Sheffield Medico-Legal Centre in the UK. A
unique institution in Brazil, CEMEL gained both national and international acknowledgement when
its work was the subject of an article by Adam (2003, 13) in the scientific journal Nature.
In 2005, a new Laboratory for Forensic Anthropology was established at CEMEL as a result of the
UK collaboration and financial support from the United Kingdom Foreign and Commonwealth
Office Global Opportunities Fund (FCO-GOF). This capacity-building partnership resulted not only
in laboratory infrastructure, but also bilateral exchanges and training in forensic autopsy, forensic
anthropology, forensic facial reconstruction and forensic DNA profiling. Practical and pragmatic
procedures for anthropological analysis of human remains (Soares and Guimarães 2008, 7; Crocco
et al. 2008; Guimarães et al. 2009; Francisco et al. 2011, 231) were developed by CEMEL,
specifically focused on forensic human identification in the challenging tropical environments of
Brazil. These proved useful in local conditions and were adopted by the regional state Medico Legal
Institute (IML) leading to a substantial increase in the rate of identification of skeletonised and
partially-skeletonised human remains (Soares and Guimarães 2008, 7; Francisco et al. 2011, 231).
In 2008, the forensic anthropology protocol was enhanced via a partnership with Dr. Ricardo Alves
da Silva from the Faculty of Odontology of Ribeirão Preto, University of São Paulo (FORP-USP) to
permit extended odontological analysis.
In 2010, the Laboratory for Forensic Anthropology was approached by the Federal Police (Policia
Federal) – a national civilian police agency whose role is equivalent to the US Federal Bureau of
Investigation – with a request to provide training in forensic anthropology for its official experts.
This resulted in a new partnership offering the prospect of academic qualifications for federal police
scientists, and giving the University access to new forensic anthropology cases. The partnership

between these institutions was essential in enabling them to participate in the work of the Grupo de
Trabalho do Araguaia in its search for the remains of victims of the military dictatorship.
Finally, CEMEL has recently been tasked with establishing national reference standards for forensic
anthropology (FAPESP 2013), a particularly significant issue given the diverse ancestry and extent
of admixture and intermarriage in the Brazilian population. These guidelines, however, address
methods analysis of remains. Standards for recovery of remains are anticipated to be included in a
separate protocol.
EXAMPLES OF FORENSIC ARCHAEOLOGY AND ANTHROPOLOGY IN BRAZIL
Archaeological and forensic investigations of buried human remains typically rely on the
application of a near-identical suite of methods. They represent the interface between archaeology
and forensic sciences (Santos 2012, 1) and the suite of methods employed and potential for
investigative use vary from country to country (Evison 2009). It is difficult to establish the extent of
professional practice in forensic archaeology in Brazil. While forensic investigation of clandestine
graves is a regular feature in the Brazilian media, these investigations tend to be conducted by
police agencies. CEMEL is a notable exception, in that its experts are frequently asked by the police
to assist in recovery and analysis of buried remains. Funding for development of the field is limited,
with some academic research funding being potentially available as well as central government
support for the investigation of recent human rights abuse allegations. It is the latter agenda which
presently drives the development of forensic archaeology and anthropology in the country, with
historical investigations also being prominent in the popular consciousness. Some examples from
Brazil are presented here.
Grupo de Trabalho Araguaía [Araguaía Working Group]
Location of the remains of political prisoners who disappeared in rural areas represents a particular
problem in Brazil. It is widely believed many were buried clandestinely in mass graves in legal
Guimarães, M.A., Francisco, R.A., de Abreu e Souza, R. and Evison, M.P. (2015) Forensic archaeology and anthropology in Brazil. In Groen, M., Márquez-Grant, N. and Janaway, R. (eds.), Forensic archaeology: current trends and future prospects. New York: Wiley. ISBN 978-1-118-74598-4
cemeteries and their bodies mingled with those of vagrants, in an attempt to preempt future
recovery and identification. It is believed others were buried in clandestine cemeteries or other
hidden locations. This practice is described in the book Brasil: Nunca Mais [Brazil: Never More]
(Arns 1996), written following the secret investigation of 707 cases from the archives of the
Superior Military Tribunal dating from 1961 to 1979. This book exposes the extent of political
repression in Brazil during the dictatorship years.
The Grupo de Trabalho Araguaia (GTA) (The Araguaía Working Group) was established in 2011
with the aim of locating and identifying the remains of the dead from one such rural locality as a
consequence of the Araguaia Guerrilla War (1966-1974). This war was the result of an insurrection
movement formed by the Communist Party of Brazil (Partido Comunista do Brasil (PCdoB)) in
opposition to the military dictatorship, with the aim of instigating a socialist revolution in Brazil
similar to those of Cuba and China. The movement started during the late 1960s and early 1970s in
a region of the Araguaía River known as ‘Bico do Papagaio’ [‘Parrot´s Beak’], where the Brazilian
States of Pará, Tocantins and Maranhão meet. The guerilla group numbered about 70 members –
the exact number is still uncertain – and had the support of part of the local population, which was
also involved in the conflict. The guerrillas were gradually eliminated by troops from the military
dictatorship between 1972 and1974. Their remains are anticipated to be spread within an area of
approximately 7 000 km2, but most are probably concentrated between the cities of Xambioá
(Tocantins State), São Geraldo do Araguaia and Marabá (Pará State).
The GTA was mandated as the consequence of an agreement between the First Federal Court of
Brasília and the Inter-American Court of Human Rights of the Organization of American States
(OAS) and established following the enactment of Inter-Ministry Ordinance no1 (Brasil 2011b) by
signatories from the Ministry of Justice and Ministry of Defense, and the National Human Rights
Secretary (SDH/PR). The GTA replaced a pre-existing group founded in 2009 (Brasil 2009) and is
composed of forensic medical experts, forensic anthropologists, archaeologists, geologists and
geophysicists, sociologists, historians, journalists and other university representatives and

independent observers (including relatives of the victims), and has the logistical support of the
Brazilian Army. Professionals from the humanities and social sciences work on information
collection from witnesses who lived – or still live – in the area, as well as from technical reports
from previous investigations, and specialised literature from libraries, public institutions and private
companies. Their main objective is to locate burials in official or clandestine cemeteries or in open
areas like fields and forests (the location is inside the Amazon region). Professionals from geology
and geophysics work on surveying areas of interest for possible human remains using Ground
Penetrating Radar (GPR). Forensic anthropologists from the Medico Legal Institutes of Brasília and
Goiânia, the Brazilian Federal Police and CEMEL are responsible for the excavation and
exhumation of remains using the established techniques of forensic archaeology and anthropology.
In an innovative approach to forensic investigation, the archaeology team led by Drs. Valéria
Cristina Ferreira e Silva and Rafael de Abreu e Souza has established a systematic survey of surface
and subsurface finds as a precursor to excavation at the military bases of Xambioá and Urutu, which
were used as prison camps during the guerrilla war. The objective has been to establish the pattern
dispersal of artifacts in order to characterise different areas of activity, which can then be used to
construct a contra-discursive memory and history of events. This novel perspective is part of a
movement intended to enhance understanding of wider contexts of recent internal conflict in Latin
America – via an ‘Archaeology of Repression’.
The GTA is probably the most substantial public initiative in Brazil undertaking forensic
archaeological investigation. There are two archaeologists contributing to the project, whose
backgrounds are in historical archaeology – especially that relevant to recent political conflict – and
who have some training in forensic procedures. Up to this date, 25 individual human remains have
been located and recovered for further investigation – such as textile analysis and DNA profiling –
in order to establish whether or not they are victims of the guerilla war.

Despite much socio-political interest in the forensic archaeological investigation of the crimes of
the military dictatorship, the most well-known work among the general public in Brazil probably
relates to the investigations of the Luz Monastery and of the first emperors of Brazil.
Funerary Archaeology of the Luz Monastery
The excavation of well-preserved human remains from the Luz Monastery in São Paulo City is
described by Fuzinato et al. (2009, 17). One of the most interesting finds – and one which caused a
national sensation in Brazil – was that of two female bodies discovered buried in an embrace.
Difficulties arising from ambiguous legislation that affects forensic archaeological investigation are
also described, and the authors recount the list of laws and regulations involving various different
institutions that can be encountered. They also emphasise the important contribution forensic
pathologists and other forensic experts can make to the preservation of the archaeological heritage.
Studies in forensic archeology applied to the human remains of the first emperors of Brazil
Deterioration of the funerary monuments of the first Emperor of Brazil, Dom Pedro I (Pedro IV of
Portugal), and his two wives, Empress Dona Maria Leopoldina von Habsburg-Lorraine and
Empress Dona Amélia de Beauharnais-Leuchtenberg, led to the excavation and analysis of their
remains. Although initially intended to establish the state of preservation of the remains, the study
revealed details of forensic significance. Dona Maria Leopoldina’s bones showed no signs of
fractures, contrary to a popular belief that she may have died as a consequence of falling from the
stairs of the palace during an argument with her husband the Emperor. The skeleton of the Emperor,
however, presented with two fractured ribs compatible with a riding accident, which may have
resulted in a pneumothorax (Ambiel 2013).
This forensic archaeological and anthropological study was probably the first to receive
considerable attention not only from the academic world, but also from the general public, leading
to wider popular interest in the field. Contributions of forensic archaeology and anthropology to

Other Studies
While the work of the GTA offers an outstanding example of the contribution of forensic
archaeology and anthropology to criminal justice and the safeguarding of human rights, its wider
role in public health and safety is frequently forgotten. Preliminary models for the study of utility
and efficacy in forensic anthropology and archaeology have been offered by Evison et al. (2012a,
b), which compared patterns of practice in Brazil in relation to other international centres. These
studies suggest effectiveness can be significantly enhanced via improvements in feedback from
investigative agencies, and better communication and integration in the investigative and
prosecutorial use of forensic archaeology and anthropology. The authors suggest that changes in the
law in Brazil may assist in the investigation and prosecution of homicides relating to organized
crime and ‘extra-judicial executions’. The authors also note, for example, the hugely
disproportionate number of male fatalities encountered in forensic anthropology case work, whether
due to homicide, suicide or natural causes – raising the question of whether gender discrimination is
resulting in the neglect of the human rights of men and boys in many countries.
CONCLUSIONS
Practice in Brazil conforms to broad definitions, including both ‘the application of archaeological
theory and methodology for the search and excavation of remains in a crime scene’ (Hunter and
Cox 2005; Santos 2012, 1) and ‘the use of archaeological practices to search, identify and analyze
human remains from crimes as well as to recover evidences of how, when and who promoted that
fact’ (Santos 2012, 1). The close interface between forensic archaeology and anthropology in Brazil

makes both areas almost indistinguishable. Practitioners can come from either sub-discipline or may
originate from specialisations such as history, anthropology, sociology, biology, biomedicine,
odontology or medicine. The few training opportunities available are spread around the country,
and there are no national standards or system of accreditation. It is necessary to keep in mind that
while forensic archaeology and anthropology expanded in other countries – like the USA and UK –
from the early 1970s (Santos 2012, 1), Brazil was under a military dictatorship. The development of
scientific tools and techniques useful to solving crimes that could include those of the government
was undesirable. It was not until the socio-political environment became favourable to the
development of sciences formerly threatening to the dictatorship status quo that progress could
begin.
Contemporary practice does recognise, however, that forensic archaeology and anthropology
represent more than excavation and osteology. Forensic facial reconstruction from the skull,
forensic facial comparison, and low-template DNA analysis of skeletal remains are also undertaken
in Brazil, and practitioners conduct relevant research in these areas, reflecting the cross-disciplinary
nature of the field (Evison et al. 2012a, 85). Furthermore, there is considerable opportunity to
develop dialogue between more traditional archaeologists and forensic practitioners, who have legal
authorisation to deal with crime scenes but not necessarily with archaeological sites – and vice
versa – with the aim of defining common objectives, responsibilities and proposals for changes in
legislation that will lead to their formal acceptance.
The wider significance of forensic archaeology and anthropology to the rule of law and the
safeguarding of human rights is of contemporary as well as historical importance, in Brazil as it is
elsewhere. There is now no excuse for forensic archaeology and anthropology to remain forgotten
sciences, as there was during the time of political repression.
