NIJ/NIST Publishes Biological Evidence Preservation Handbook 

A new handbook by the National Institute of Standards and Technology (NIST) and the Department of Justice’s National Institute of Justice (NIJ) provides forensic laboratories, law enforcement agencies and the judicial system with state-of-the-art guidelines and recommended best practices for preserving biological evidence so that it is available at any time to solve "cold cases," confirm the guilt of criminals, or exonerate the innocent.
