Study Notes
Latent Fingerprint Enhancement
- Super glue fumes can reveal latent fingerprints on non-porous surfaces, like glass bottles.
- Oblique ambient light or white light sources are used to visualize fumes adhering to prints.
Types of Surfaces
- Non-Porous Surfaces: Best for collecting latent prints; requires specific handling and packaging.
- Porous Surfaces: Latent prints remain stable; special care needed during collection.
- Semi-Porous Surfaces: Require attention, but details are less emphasized in handling.
Packaging of Evidence
- Latent fingerprint evidence is extremely fragile and can degrade easily.
- Excessive handling or improper packaging can lead to destruction of latent prints.
Packaging Protocols
- Non-Porous Items: Should be stored in paper bags or cardboard boxes secured with plastic ties to prevent movement; avoid plastic bags.
- Wet items must dry before packaging or undergo super glue fuming.
- Each item should be packaged separately to minimize cross-contamination.
Securing Evidence
- Evidence must be secured within packaging to prevent loss of fingerprints, often using strings.
- Latent prints on adhesive tapes can be preserved by mounting on cardboard and sealing in a box to protect from contamination.
Common Mistakes to Avoid
- Do not cover latent print surfaces with evidence tape.
- Avoid wrapping non-porous items in cotton, cloth, or polythene bags to prevent damage to prints.
- Do not pack multiple items together without proper securing mechanisms to prevent damage.
Conclusion
- Correct sealing and packaging methods are essential to preserve latent fingerprint evidence for successful examination and analysis.
