Crime Scene Processing and Recovery of Physical Evidence from Sexual Assault Scenes

This training module provides guidance on crime scene processing, a systematic, meticulous, and scientific process that law enforcement investigators should employ in every major criminal investigation.

DNA and Biological Evidence

This training module explores the complex role of DNA and other biological evidence in a sexual assault investigation. A number of resources and tools are provided, along with a series of complex and interactive case examples. The module was co-authored by EVAWI’s Joanne Archambault and Kim Lonsway, along with Dr. Patrick O’Donnell (Supervising Criminalist, San Diego Police Department) and Lauren Ware (Chief of the Forensics and Special Investigative Branch at the Federal Law Enforcement Training Center).

In this 7-part series of Training Bulletins, we explore the role of DNA and other biological evidence in a sexual assault investigation. It is based on our 32-hour OLTI module, and includes a number of resources and tools, along with interactive case examples.

Untested Evidence and Cold Case Investigation

This training module is designed to help communities address the complex challenges of untested evidence in sexual assault cases. While the material is largely written with reference to cold cases, much of the guidance applies equally to current sexual assault cases and investigations that have been recently inactivated or suspended. Specific guidance is offered for notifying victims that their investigation has been re-opened, keeping victims informed of the status of their case, and providing ongoing victim support throughout the criminal justice process.

PowerPoint on DNA in a Sexual Assault Investigation

This PowerPoint presentation was developed by Joanne Archambault and Kim Lonsway, in collaboration with Brian Lew of the San Diego Police Department’s Forensic Biology Unit.  It explains the nature of the “DNA backlog” and explores the role of DNA in a sexual assault investigation.  Topics include the primary sources and purposes of DNA evidence, the three-tier structure of CODIS (on the local, state, and national level), and strategies for evidence assessment, particularly when prioritizing laboratory service requests for the analysis of particular pieces of evidence based on specific case facts.  The presentation also covers the historical background as well as the future promise - and challenge - of DNA technologies in the context of sexual assault investigations.
