ANTH 1010: Week 8 Lecture

Week Eight: Tuesday, March 5, 2019

This week’s lecture on subfields of biological anthropology the focus was on forensic anthropology, which is the use of human osteology and archaeology to legal investigation of human remains. A large point of focus was trauma; the different aspects of trauma, the nature of trauma, the importance of the location and pattern of trauma and so forth. We also spoke briefly about forensic entomology or the use of insects and other bug activity in a body to determine time of death.

In relation to the nature of trauma, we talked about the three different time classifications used to describe the time in which an injury or trauma was sustained by the victim. First, there was an antemortem trauma which is an injury that occurred sometime before the victim’s death and therefore an anthropologist would be able to clearly see remodeling on the bone. Second, there was a perimortem trauma which is an injury that occurred right before the death of the victim and could possibly also serve as cause of death. Some characteristics of a perimortem trauma include sharp edges surrounding the injury, hinging, fracture lines, and hematoma staining. The final one was postmortem trauma which is an injury that occurred after the victim had already died, an example of this would be cut marks on the bone of a victim that was dismembered by their killer. Some characteristics of a postmortem trauma include clean edged wounds, no hinging, and very little evidence of fracture lines.

We also talked about the location and pattern of trauma and how it can help a forensic anthropologist determine a great number of different details about the manner of the individual’s death. You could tell from the location and pattern of a trauma whether the wound was self inflicted or not, if it was accidental or done on purpose, and the sequence in which the injuries were sustained which would help establish a sequence of events.

Antemortem vs Postmortem

Understanding whether injuries or exposures occurred before or after death is a crucial part of forensic profiling. These distinctions allow investigators to reconstruct timelines, assess narratives, and evaluate suspect statements through careful lab work, analysis, and scientific observation, all while maintaining ethical and professional boundaries. Core Postmortem Indicators 1. Pallor Mortis • Immediate paleness of the skin after death due to stopped circulation. • Provides early context for estimating time of death. • Alone it’s not precise, but complements other postmortem indicators like livor and rigor mortis.

2. Livor Mortis (Postmortem Lividity) • The settling of blood in the body due to gravity. • Can indicate position of the body after death and whether it has been moved. • Helps narrow down timelines and assess staging attempts.

3. Rigor Mortis • Stiffening of muscles after death. • Timing of onset and relaxation can provide rough postmortem intervals. • Variations can hint at environmental factors or cause of death.

4. Algor Mortis • Cooling of the body over time. • Can be used to estimate time of death, though environmental conditions affect accuracy.

5. Injuries vs Postmortem Changes • Differentiating ante‑ vs post‑mortem injuries (e.g., bruises, cuts). • Presence of inflammation or hemorrhage indicates living tissue response, crucial for profiling intent and timing.

6. Stomach Contents • Timing of last meal can help establish chronology of events. • Can indicate location or movement if food traces correspond to specific environments.

7. Decomposition Patterns • Rate and type of decomposition can provide timeline estimates, depending on environmental exposure. • Certain decomposition signs can reveal attempts to conceal or move the body.

8. Toxicology Findings • Presence of alcohol, drugs, or poisons in blood or tissues. • Can provide context for behavior or susceptibility to certain actions before death. • Links physiological state to potential motive or vulnerability.

9. Trace Evidence • Fibers, soil, or particulate matter on the body. • Can connect a person to a scene, reveal movement, or support/reject statements.

10. Signs of Struggle • Defensive wounds, tissue damage, or contusions. • Help interpret interactions before death and may indicate relationship to suspect.

Fire and Smoke Indicators 1. Soot in the Trachea and Bronchi • Presence of soot in the airways indicates the individual was breathing when exposed to smoke, showing the fire occurred while the body was alive. • Absence of soot suggests exposure after death, helping verify or challenge witness statements or suspect claims.

2. Elevated Carboxyhemoglobin Levels in Blood • High carboxyhemoglobin levels demonstrate carbon monoxide was inhaled while circulation was active. • Critical when determining whether death occurred before or during a fire, providing insight into possible timelines of the incident.

3. Thermal Injury Patterns • Certain burn patterns are only present in living tissue, while others may develop postmortem. • Observing these patterns enables investigators to distinguish between injuries that contributed to death and those that occurred after death, informing the investigation of staging, concealment, or causality.

Profiling Implications: By analyzing these physiological and pathological indicators, forensic professionals can:

• Corroborate or contradict suspect and witness statements • Narrow down timelines of events • Identify potential staging or secondary factors in crimes • Assess whether the focus is on concealment versus actual cause of death

This approach emphasizes interpretation over execution, allowing criminal profilers to understand behaviors and event sequences without divulging operational procedures.

Antemortem Assessment Without Postmortem Evidence When no body is recovered, and postmortem examination is impossible, criminal profiling becomes significantly more complex and limited. Investigators must rely on indirect indicators and psychological reconstruction rather than biological confirmation.

If there is:

• No blood spatter or trace evidence indicating injury or death • No body available for pathological analysis • No clear physical indicators of cause or timing of death

Profiling requires reconstruction of multiple hypothetical scenarios, drawing on behavioral patterns, victimology, opportunity, motive, and environmental context. This process involves deep psychological inference and comparative reasoning rather than confirmation.

Without postmortem findings, conclusions remain probabilistic rather than definitive. Statements, timelines, and motives cannot be biologically verified, and deception becomes harder to detect. This limitation increases the risk of misinterpretation, false assumptions, or narrative-driven reasoning.

For this reason, postmortem examination is essential to criminal profiling. The body provides objective data that anchors psychological analysis to reality, transforming speculation into evidence-based interpretation. It allows profilers to move from imagined possibilities to validated sequences of events, strengthening the identification and assessment of suspects.
