3. Securing and Collection Evidence
All evidence must be properly packaged, sealed, and labeled.
Specific procedures/techniques for evidence collection and storage must be followed.
Moist biological evidence is stored in breathable containers so evidence can dry out, reducing the chance of mold contamination.
After drying, the evidence can be packaged in a paper bindle and placed in a plastic or paper container.
The outer container is then sealed with tape and labeled with the signature of the collector written across the tape.
