How should samples be collected for submission to the Forensic Biology Unit?

Samples should be collected in a way that will avoid sample destruction and degradation.  Biological evidence is best preserved in a dry, cooler

environment.  Items of evidence should be packaged in brown paper sacks, evidence envelopes, or similar packaging material.  Biological

evidence should never be packaged in plastic bags.  Specific packaging information can be found in the Evidence Collection Manual.
