Summary
Rodent bite marks on deceased individuals are often circular with serrated edges. These postmortem injuries are common on exposed body parts, particularly in homeless populations or low-income settings.
Area of Science:
- Forensic Pathology
- Zoology
Background:
- Postmortem artifacts on human remains can be challenging to interpret.
- Rodent activity is a potential factor in body decomposition and artifactual damage.
Observation:
- Presents five cases of postmortem rodent bite injuries on male decedents aged 41-89.
- Injuries characterized by circular appearance, finely serrated margins, and irregular edges.
- Diagnostic features include distinct parallel cutaneous lacerations from incisors; claw marks absent.
Findings:
- Mice and rats were identified as the causative agents, with one case of mixed activity.
- Injuries predominantly occurred on exposed areas like eyelids, nose, mouth, and hands.
- Postmortem rodent activity can also affect clothed areas, especially in specific environmental contexts.
Implications:
- Understanding rodent artifact patterns aids forensic investigations.
- Highlights the importance of considering environmental and socioeconomic factors in postmortem findings.
- These findings are particularly relevant for cases involving homeless individuals or those in low socioeconomic settings.
