Collecting paper evidence involves careful handling and documentation to maintain its integrity for examination. Based on established procedures, the process includes specific steps to ensure proper collection and preservation.
Key Steps for Collecting Paper Evidence
Proper collection begins with preparation and meticulous execution. The core actions involve documentation, protection, and secure packaging.
Step 1: Document the Evidence In Place
Before disturbing the paper documents, it is crucial to record their original location and condition.
- Photograph the documents in place. This visual record provides essential context, showing how the documents were found relative to their surroundings and other items. This helps preserve the scene's integrity digitally before collection occurs.
Step 2: Ensure Personal and Evidence Protection
Handling evidence requires precautions to avoid contamination or damage.
- Wear new, unused, clean latex or nitrile gloves. This protects the evidence from oils, fingerprints, or foreign contaminants from your hands, and also protects you from potential hazards on the documents. Using new gloves for each set of evidence or each location prevents cross-contamination.
Step 3: Properly Containerize and Label the Evidence
Secure packaging is vital for transporting and storing paper evidence while maintaining a clear chain of custody.
- Label a collection container large enough for the item. Choose an appropriate container like a box, envelope, or plastic tub that fits the paper evidence without folding or damaging it.
- Include identifying information on the container label. This information must include:
- Case number
- Date of collection
- Exhibit number (a unique identifier for the collected item)
- A brief description of the paper evidence
- Your name (the collector's name)
Following these steps helps ensure that paper evidence is collected correctly, preserving its evidentiary value for further analysis.
