The Forensic Technology Center of Excellence (FTCoE) is leading an effort to organize and transfer knowledge and best practices of sexual assault response to the criminal justice community. Whether through webinars, podcast episodes, reports, or conferences, the FTCoE is working to address the systemic challenges that impede the investigation of criminal sexual assaults in the United States.
The organization of education materials for those responding to and investigating criminal sexual assault is a major component of our efforts toward sexual assault response reform. In that respect, the Fact Sheets below were designed to feature webinars and additional resources related to specific topics within the sexual assault response reform movement. Click on the icons to open, download, print, and share these fact sheets with SANEs/SARTs, investigators, first responders, and anyone else who could benefit from having access to this information.
NIJ’s FTCoE and Forensic Laboratory Needs Technology Working Group
Recognizing the many challenges associated with adopting new technologies and other innovations in forensic science organizations, the National Institute of Justice (NIJ) formed the Forensic Laboratory Needs Technology Working Group (FLN-TWG) in 2018. FLN-TWG provides a forum for which forensic practitioners and researchers can develop coordinated approaches to addressing technology implementation challenges for the forensic science community.
Housed at NIJ and supported by the Forensic Technology Center of Excellence (FTCoE), FLN-TWG membership is comprised of crime laboratory directors or managers and academic researchers who meet regularly to share ideas, assess the impact of new technologies on the criminal justice system, and identify paths forward for implementation. The group’s mandate encompasses the full range of needs facing federal, state, local, and tribal jurisdictions; FLN-TWG is designed to clear roadblocks that have prevented broad, successful adoption of promising technologies.
This in-brief provides a summary of FLN-TWG’s goals and outputs of the first meeting and provides a list of programs and resources that can promote technology adoption by crime laboratories.
“I’m very pleased to welcome the newly created working group members and grateful for their willingness to take part in this important endeavor. I look forward to hearing their valuable input and working together toward strengthening the relationship between the Justice Department and forensic science practitioners.”
—David Muhlhausen, NIJ Director

The National Institute of Justice (NIJ) is committed in their efforts to support scientific advancement, evidence-based practices, and community awareness of our Nation’s sexual assault response. As NIJ’s Director, Dr. David B. Muhlhausen, indicated, “our nation’s forensic laboratories have the ability to find and test smaller and smaller amounts of crucial evidence and get quality results for cases that years ago would have been unattainable” . NIJ’s numerous sexual assault response resources, including the National Best Practices for Sexual Assault Kits: A Multidisciplinary Approach, are summarized in this NIJ Director’s Message [1, 2].
Sexual assault remains prevalent in the United States, with an average of 300,000 cases reported to law enforcement each year . However, another 600,000 go unreported . The circumstances of and trauma resulting from a sexual assault can pose a challenge to investigators. For example, witnesses are not always present; the impact of trauma or incapacitating substances, such as alcohol, may affect the victim’s ability to recount details of the incident; and frequently, corroborating evidence is limited.
DNA evidence, while valuable, is not always probative or present in every case: many DNA samples do not meet the quality standards required to be uploaded into CODIS (38% of profiles were found to be ineligible as noted from recent NIJ-supported research ). Even in cases where a DNA profile is present and is CODIS-eligible, a CODIS hit occurs only about half of the time . Additionally, a DNA profile may provide limited probative value in situations where sexual contact is not disputed. Thus, many types of additional physical evidence play a critical role in the investigation and prosecution of sexual assault cases.
Physical evidence collection, submission, and analysis can be an effective and necessary means of reconstructing at least some of the events that occurred during a sexual assault. Physical evidence provides value to investigations even if a DNA profile is developed and probative, as it can be used to corroborate and supplement a greater understanding of the circumstance and make a stronger case. This three-part Beyond DNA In-Brief series highlights types of physical evidence that can provide crucial information about a sexual assault, so that key stakeholders in the criminal justice community ultimately obtain just resolutions for these crimes.

“Based on our findings, jurors were more likely to find a defendant guilty than not guilty even without scientific evidence if the victim or other witnesses testified, except in the case of rape.” —Honorable Donald E. Shelton,The ‘CSI Effect’: Does It Really Exist?, National Institute of Justice (NIJ)

“Sexual assault evidence should be evaluated holistically. The identification of the type of biological fluid may further substantiate and clarify how events took place.” -Dr. Patricia Melton, RTI International

“Because of the effects that CNS depressants can have on memory and the subsequent reporting of suspected DFSA by potential victims, the true prevalence of this crime may never be fully realized.” – Marc LeBeau, FBI Laboratory
The NIJ and the FTCoE provide resources for sexual assault response, including:
• The National Institute of Justice’s National Best Practices for Sexual Assault Practices: A Multidisciplinary Approach provides 35 recommendations to improve evidence collection and tracking procedures, investigative considerations, communication strategies, and more.
• The Forensic Technology Center of Excellence (FTCoE) published a comprehensive report on current knowledge and best practices for sexual assault response teams, including considerations for evidence collection.
• The Sexual Assault Kit Initiative (SAKI) provides resources on these issues, including insight for cold cases where DNA may not be dispositive.
• The NIJ introduces the value of physical evidence in Sexual Assault Cases: Exploring the Importance of Non-DNA Forensic Evidence. The NIJ has also published a variety of resources around sexual assault response
• The FTCoE has collaborated with the Center for Nursing Excellence (CFNEI) to develop an online sexual violence glossary to standardize language amongst medical, law enforcement, and legal professionals.
