- Legal Medicine
Background:
- Defense injuries offer critical insights into assault dynamics and manner of death.
- Understanding these injuries is vital for accurate forensic investigations.
Purpose of the Study:
- To analyze the prevalence, patterns, and forensic significance of defense injuries in homicide cases.
- To establish correlations between defense wound characteristics and weapon types.
Main Methods:
- Retrospective observational study of 60 homicide cases with documented defense injuries.
- Data collected from autopsy reports, crime scene records, and inquest papers over five years.
- Injuries categorized by type, anatomical distribution, and weapon involved; statistical analysis performed.
Main Results:
- Defense injuries most common on hands (80%), forearms (65%), and fingers (40%).
- Incised wounds (60%) predominated in knife attacks; contusions/fractures (55%) in blunt force trauma.
- Significant correlation found between defense wound type and weapon used (p<0.05).
Conclusions:
