Touch DNA Evidence Collection in Sexual Assault Cases
April 2023
Dr. Julie L. Valentine introduces the application of touch DNA in sexual assault cases through a case study. A literature review on touch DNA is summarized to provide contextual information and research on touch DNA analysis findings in groping sexual assault cases is discussed. The webinar concludes with recommendations for multidisciplinary partners to collect, submit, and analyze evidence in sexual assault cases for touch DNA.
This webinar was hosted by the NIJ Forensic Technology Center of Excellence on April 18, 2023.
