This updated Crime Scene Investigation: A Guide to Law Enforcement is a revision of the original publication published in January 2000, and borrows heavily from that work. The original publication was based upon the work of the National Crime Scene Planning Panel and additional Technical Working Group Members. Their contributions remain as vital today as when the original Guide was published.

To develop this expanded edition, a Review Committee of recognized experts was assembled. This committee selected additional material from content developed for Department of Justice-funded crime scene projects, Scientific Working Groups and other open-source documents, which are reflected in the Reference section. Additional vetting of the material was accomplished through recognized subject matter experts.

NFSTC wishes to thank the Bureau of Justice Assistance (BJA), the National Institute of Standards and Technology (NIST) and the National Institute of Justice (NIJ) for providing input to this project.

The resulting document includes detailed procedural guides for the complete range of crime scene investigation tasks – from securing the scene to submitting the evidence. This publication provides law enforcement professionals and first responders step-by-step guidance in this crucial first phase of the justice process.

Agencies are encouraged to use this reference to enhance existing training and promote quality. While these methods can be implemented at any agency, jurisdictions will want to carefully consider the procedures and their applicability to local agencies and circumstances.



Revision of this guide was conducted by the National Forensic Science Technology Center (NFSTC), supported under cooperative agreements 2009-D1-BX-K028 and 2010-DD-BX-K009 by the Bureau of Justice Assistance, and 2007-MU-BX-K008 by the National Institute of Justice, Office of Justice Programs, U.S. Department of Justice.
