Study Notes
Forensic Anthropology
- Forensic anthropology is the application of skeletal analysis to legal questions.
- Specialists analyze human remains to determine age, sex, ancestry, stature, and trauma to aid in criminal investigations and identification.
- Skeletal features are used to distinguish between individuals and populations.
- Trauma analysis helps estimate the cause and manner of death.
- Forensic anthropologists may also assess the presence of decomposition and the time elapsed since death.
Bone Analysis
- Bone analysis is a critical component of forensic anthropology.
- Microscopic features (e.g., bone structure, markings from disease or trauma) provide information about the deceased.
- Bone density, shape, and size can give clues about lifestyle and physical characteristics.
- Age estimation is based on markers in the bone's growth, fusion of epiphyses, and other indicators.
- Sex assessment is based on distinctive skeletal differences between males and females.
- Ancestry determination is made based on characteristics associated with particular populations.
Trauma Analysis
- Trauma analysis examines injuries on skeletal remains to understand the cause of death.
- Examination of fractures and signs of blunt force trauma, sharp force trauma, and gunshot wounds are crucial in forensic investigations.
- Analyzing the location, patterns, and types of injuries can help reconstruct the events surrounding the death.
- The presence of defensive wounds suggests victim resistance.
- Analysis may involve comparing injuries to known weapons or tools.
Forensic Archaeology
- Forensic archaeology is the application of archaeological methods and principles to legal proceedings.
- It involves excavation and analysis of human remains and evidence within archaeological contexts.
- Site survey, mapping, excavation and careful documentation are key aspects.
- Determining the context of the remains within their surroundings and soil conditions can be crucial to determining time since death.
- Examining the presence of artifacts may help to corroborate information found from bone analysis.
Crime Scene Investigation
- Crime scene investigation encompasses the entire process from initial response to final report.
- Forensic anthropologists and archaeologists play a role in a broader criminal investigation.
- Initial documentation and preservation of the scene is a critical part of any investigation.
- Evidence from the crime scene has to be collected, packaged, and analyzed carefully.
- Reconstruction of events is often based on observations of the scene and findings from different specialists (e.g., forensic science).
Identification Techniques
- Identification techniques play a vital role in the investigation.
- Forensic anthropology relies on comparisons of skeletal features with other known remains.
- Dental records and DNA testing are often supplementary to bone analysis methods.
- Matching dental records to skeletal remains can aid positive identification.
- Comparison to other evidence, such as clothing, personal items, or injuries, is done to aid in the identification.
- Advancements in DNA analysis can confirm or refine conclusions, specifically through mitochondrial DNA analysis for cases with incomplete skeletal remains.
