Forensic anthropologists apply their expertise in physical anthropology to legal investigations. Their work includes identifying human remains, estimating age, sex, stature and ancestry to create a biological profile. They also analyze trauma to determine cause and manner of death. Forensic anthropologists help in mass disasters by separating and identifying commingled remains. They also use their archaeological skills to locate buried evidence at crime scenes. Anthropometry, the systematic measurement of the human body, is another tool used for individual identification in forensic investigations.

- 8. Scope of Forensic Anthropology • The routine scope of this discipline is the identification of: – Skeletonized Remains – Badly Decomposed Cadaver – Unidentified Human Remains – Ageing of Individuals – Mass Disaster and Homicide Victims – Discrimination of Commingled Skeletons or bones
- 9. Scope of Forensic Anthropology in Homicide Investigation • Forensic Anthropologists are trained physical anthropologists who apply their expertise to solve cases of homicides by Identifying: – Race – Sex – Age – Stature – Ethnicity – Culture – Religion – Caste – Possible career and/or behavior – Ante-, Peri- and Postmortem injuries – Time Since Death – Facial Reconstruction (2D and 3D) }In Some Cases
- 11. Case Study • Adolph Luetgert was a prosperous sausage manufacturer whose business was beginning to fail. • Luetgert claimed that his wife had run off with another man, but a search of his factory led to a foul smell at the bottom of a large vat. • There, two of his wife’s rings, a corset stay, and several small bones were found; thus Luetgert was accused of killing his wife. • George Dorsey was the first expert forensic analyst to receive a doctoral degree in anthropology by Harvard. • He was assigned to the Luetgert case and revealed his findings to the court. • Among the bones, rings, and corset stay were other pieces of evidence that made the case a win for Dorsey. • This case acquired national recognition and for months, the sale of sausages had fallen as it was rumored that pieces of Luetgert’s wife was mixed in with the product.
- 12. Scope of Forensic Anthropology in Mass Disasters • Whether a result of human or natural circumstances, a disaster is likely to involve a range of extreme forces such as: • Heat (burning), • Impact (G-force, wave) • Crushing (structure collapse) • Explosion, • Freefall (impact) and/or • Environmental influences (temperature; humidity; water—warm, cold, salt, fresh; carnivore/rodent activity)
- 13. • Disasters resulting in mass fatalities commonly present a range of differentially preserved remains that may include bodies and/or body parts that are: – Intact – Fairly intact – Decomposed Fragmentary – Commingled – Burned or cremated – Partially burnt – Distorted – Buried – Or a combination of several of these states of preservation.
- 14. Phases of Disaster Victim Identification • Phase 1- The Scene – Identifying the presence of skeletal remains. – Identification of the spatial temporal relationships between the bodies and associated evidence. – Position of Body – Number of Individuals – Establishing if there are more than one individual present (Commingled Remains)
- 15. • Phase 2- The Mortuary • Separation of osseous and non-osseous remains. • Separation of human and non-human bone material. (Anthropologists were required to distinguish human from nonhuman remains in the New York September 11 terrorist attacks on the World Trade Centre where many restaurants were located in the area of the destruction) • Separation of recognizable vs. non-recognizable fragments that require DNA analysis. (Retrieval and identification of soft tissue fragments in the 2002 Bali incident, especially from individuals thought to be at the epicenter of the explosion, contributed to the identification of many of the deceased) • Separation of Commingled Remains. • Analysis of small fragments of bone from any region in the body. • Siding to left and right of skeletal fragments. • Analysis of cross-sections of bone in soft tissue masses. • Analysis of incinerated remains with no soft tissue.
- 16. • Evaluation from Phase 2 enables the forensic anthropologists to: – Determine the minimum number of individuals present. – Establish a biological profile (Race, sex, age, stature etc.) of individuals. – Provide an opinion on ante-, peri- and post- mortem traumas. • Phase 3- Ante-mortem Data Collection • Phase 4- Reconciliation or Opinion Formation
- 17. Case Study • 11 September 2001- Attackers from Al-Qaeda attacked World Trade Center and The Pentagon. • Casualties- 2996 and 19 Hijackers • Weeks after attacks death toll rised to 6000 • Only 1600 individuals were identified. • The medical examiner collected over 10,000 unidentidied bone and tissue fragments. • More of the bone fragments still found in 2006 when workers planned to rebuild Deutsche Bank. • In 2010, a team of anthropologists and archeologists found 72 more bones from Fresh Kills Landfills. • Identification process is still going on. • On March 20, 2015, 1,640th Victim was identified and there are still 1,113 victims who have not been identified.
- 18. Forensic Archaeology • Archaeology or archeology, is the study of human activity in the past, primarily through the recovery and analysis of the material culture and environmental data that has been left behind by past human populations, which includes artifacts, architecture, biofacts (also known as eco-facts) and cultural landscapes (the archaeological record). • Forensic Archeology is the application of this study in legal setting or in courts of law. • Forensic archaeologists are employed by police and other agencies to help locate evidence at a crime scene using the skills normally used on archaeological sites to uncover evidence from the past. • Forensic Archaeologists are employed to locate, excavate and record buried remains, the variety of such targets is large and each case is unique in its requirements (hence the need to use an experienced professional forensic archaeologist).
- 19. • However whilst the types of target that forensic archaeologists are asked to investigate are diverse the most common can be generally grouped as follows: – Buried small items or personal effects from a victim of crime, which may be used to corroborate a statement or contain other evidential value. This group includes evidence buried by a perpetrator of a crime to hide their involvement (e.g., weapons, money, mobile phones, etc.) – Potential gravesites, forensic archaeology attempts to locate and recover any human remains whilst also recording all evidence in association with the remains to reconstruct events that took place prior to the burial of the victim or victims. – The grave may be sought as part of an investigation of an unsolved crime or may in some rare cases result from information gained from an individual already convicted of the crime in the absence of a grave.
- 20. – Surface body disposals where a recent victim has been concealed under fallen walls, tree branches, rubbish etc. In this case the application of archaeological stratigraphic recording to the removal of the layers of material concealing the victim can be of great evidential value. The collaboration of a forensic archaeologist, entomologist and forensic botanist in cases of this sort can allow very detailed reconstructions of the timing of the disposal and have in previous cases been decisive in proving a death was not accidental but an intentional criminal act. – Mass graves, usually as part of an international organisation's investigation (e.g. the United Nations) where the recovery of remains is focused on both evidential recovery for future indictments (e.g. The War Crimes indictments in the International Criminal Court) and the identification of individuals remains for surviving relatives which may form a crucial role in reconciliation and breaking the cycles of violence that can continue to occur over generations in such conflicts. – Civil cases involving buried evidence (e.g. locating former fence lines
- 21. – Excavating a grave under archaeological conditions can provide valuable evidence on the time and circumstances of burial, the manner of death, and the tools and techniques used for interment. – Associated disciplines can aid in the fine detail from such investigations, for example the analysis of pollen, plant remains and ash from within a grave by a forensic botanist may allow the reconstruction of the environment a victim has been in prior to their burial in the grave. Similarly a Forensic Entomologist may help with the analysis of insect remains to determine the time of day or year a victim was buried.
- 22. Anthropometry • Anthropometry (from Greek ἄνθρωπος anthropos, "man", and μέτρον metron, "measure") refers to the measurement of the human individual. • It is an early tool of physical anthropology. • It has been used for identification, for the purposes of understanding human physical variation, in Forensics and in various attempts to correlate physical with racial and psychological traits. • First applied in Forensics by Sir Alphonse Bertillion in 1883 and called his system Bertillonage. • Anthropometry involves the systematic measurement of the physical properties of the human body, primarily dimensional descriptors of body size and shape
- 23. Applications • In Forensic Anthropology – In osteological analysis age, stature, ancestry, and sex of the skeletal remains are first determined. – The investigator may find evidence regarding cause and manner of death; however, when flesh is still found on the bone, the stage of decomposition is noted and time since death may be more effectively narrowed. – A range is also applied to stature based on the length of long bones, applied to a specific mathematical equation. • In Forensic Odontology
