Summary
Proper evidence collection is crucial for analyzing bite mark cases. This study proposes a protocol to improve the handling of forensic evidence, preventing analysis failures in bite mark casework.
Area of Science:
- Forensic Odontology
- Evidence Management
Background:
- Inadequate evidence collection has hampered bite mark analysis in recent cases.
- Lack of standardized information for police, forensic pathologists, and dentists on evidence handling.
Observation:
- Several bite mark cases were unanalyzable due to poor evidence collection practices.
- Case studies illustrate critical errors in collecting, recording, duplicating, storing, and transporting evidence.
Findings:
- Current procedures for bite mark evidence collection are insufficient.
- A significant gap exists in accessible, comprehensive guidelines for forensic evidence handling.
Implications:
- Implementing a standardized protocol can improve the quality and reliability of bite mark evidence.
- Enhanced training and clear guidelines are essential for accurate forensic analysis and legal outcomes.
