Decomposed Body in a Field: Anthropology, ID, and Manner
Skeletal remains are found in a wooded area. The remains are largely skeletonized with some mummified tissue. A forensic anthropologist estimates the individual is a male, 35–50 years old, about 175 cm tall, with a healed fracture of the left radius. There is a defect in the left parietal bone with beveling on the inner table. No clothing or identification is found. A missing-person report matches a 42-year-old man who disappeared 8 months earlier and who had a history of a left forearm fracture. The medical examiner must decide whether to certify the death, what the manner is, and how to establish identity.
1. How should the anthropologist and pathologist interpret the skull defect and establish identity?

Skull defect: A defect with inner-table beveling is classic for a gunshot entrance wound (beveling occurs on the inner table at the exit side of the bone). However, beveling can also occur with other high-energy impacts. The pathologist should examine the defect for a corresponding exit wound, fracture patterns, and any metallic fragments; if a firearm is suspected, radiograph and recover any projectile or fragments. The defect should be described, measured, and photographed with a scale. Without soft tissue, determining entrance vs. exit and the direction of fire requires careful reconstruction.
Identity: Anthropological parameters (sex, age, stature) narrow the pool but do not identify. The healed radial fracture is a useful comparative feature but is not unique. Definitive identification requires:
- DNA comparison with a family reference sample (most reliable).
- Dental records comparison (radiographs, restorations, missing teeth) - often the fastest and most practical.
- Fingerprints if tissue permits (unlikely here).
- Medical/surgical records (the healed fracture) as corroboration.
The pathologist should not certify identity on anthropological grounds alone; the report should state the biological profile and the comparative features, and identity should be established by DNA or dental comparison before the death certificate is issued.
2. How should the manner of death be approached given the decomposition and the missing person match?
Read the worked answer
The manner determination should follow from the injury interpretation, not from the identity match.
- If the skull defect is a gunshot wound, the manner is homicide unless evidence supports accident or suicide (e.g., a weapon at the scene, a contact wound, an atypical location). A gunshot wound to the parietal region is a common homicide pattern but can occur in suicide; scene and projectile trajectory matter.
- The decomposition limits soft-tissue assessment; the pathologist should state what can and cannot be determined.
- The missing-person match is corroborative but not determinative; identity should be confirmed by DNA or dental comparison before the certificate is finalized.
- The certificate should list the cause (e.g., gunshot wound of the head) and manner based on the injury and circumstances, with a note on the limitations.
The pathologist should avoid certifying a manner based solely on the presumption that a missing person who is found dead was murdered.
