Forensic data management and database systems in forensic investigations for cases of missing and unidentified persons in Brazil.

Forensic investigations, especially those related to missing persons and unidentified remains, produce different types of data that must be managed and understood. The data collected and produced are extensive and originate from various sources: the police, non-governmental organizations (NGOs), medical examiner offices, specialised forensic teams, family members, and others. Some examples of information include, but are not limited to, the investigative background information, excavation data of burial sites, antemortem data on missing persons, and postmortem data on the remains of unidentified individuals. These complex data must be stored in a secured place, analysed, compared, shared, and then reported to the investigative actors and the public, especially the families of missing persons, who should be kept informed of the investigation. Therefore, a data management system with the capability of performing the tasks relevant to the goals of the investigation and the identification of an individual, while respecting the deceased and their families, is critical for standardising investigations. Data management is crucial to assure the quality of investigative processes, and it must be recognised as a holistic integrated system. The aim of this article is to discuss some of the most important components of an effective forensic data management system. The discussion is enriched by examples, challenges, and lessons learned from the erratic development and launching of databases for missing and unidentified persons in Brazil. The main objective of this article is to bring attention to the urgent need for an effective and integrated system in Brazil.

Considerations of coronavirus (COVID-19) impact and the management of the dead in Brazil.

During a pandemic such as COVID-19, the forensic community plays a key role in the management of the crisis, both nationally and internationally. Much has been written and disseminated regarding protocols for death investigation, infection mitigation and risks, and management of dead. However, in many contexts, the ability of forensic practitioners to follow best-practice procedures is limited by the resources available to them. This article examines some of the impact of the novel coronavirus (COVID-19) in Brazil, with emphasis on management of the dead and challenges faced by medicolegal services.

Forensic anthropology and missing persons: A Brazilian perspective.

The problem of the missing persons phenomenon in Brazil in the 21st century has become apparent, and the responses to the issue are still under development. The relatively new field of forensic anthropology and its trained professionals occupy an essential place in the investigation of cases of missing and unidentified individuals. The development of forensic anthropology in Brazil is unique among Latin American countries, who improved their expertise during the investigations of political crimes that occurred between the 1960s and 1980s in most places. The qualifications and the paths to become a forensic anthropologist in Brazil are different from other professionals who work in the field worldwide. This article addresses the issue of missing person investigations and details the work of forensic anthropologists in such cases in Brazil.

A mass sacrifice of children and camelids at the Huanchaquito-Las Llamas site, Moche Valley, Peru.

Here we report the results of excavation and interdisciplinary study of the largest child and camelid sacrifice known from the New World. Stratigraphy, associated artifacts, and radiocarbon dating indicate that it was a single mass killing of more than 140 children and over 200 camelids directed by the Chimú state, c. AD 1450. Preliminary DNA analysis indicates that both boys and girls were chosen for sacrifice. Variability in forms of cranial modification (head shaping) and stable isotope analysis of carbon and nitrogen suggest that the children were a heterogeneous sample drawn from multiple regions and ethnic groups throughout the Chimú state. The Huanchaquito-Las Llamas mass sacrifice opens a new window on a previously unknown sacrificial ritual from fifteenth century northern coastal Peru. While the motivation for such a massive sacrifice is a subject for further research, there is archaeological evidence that it was associated with a climatic event (heavy rainfall and flooding) that could have impacted the economic, political and ideological stability of one of the most powerful states in the New World during the fifteenth century A.D.
