The purpose of this module is to improve the use of forensic examinations to collect evidence from the bodies and clothing of both victims and suspects during a sexual assault investigation. The module goes beyond simply explaining the procedures that are used during victim and suspect forensic examinations. It also explores the different types of evidence that may be gathered during these examinations and describes how this evidence can be used to advance a sexual assault investigation. It also gives participants an opportunity to apply what is learned through case study activities. Ultimately, the goal of this module is to encourage professionals involved in these cases to push past traditional ways of thinking about evidence, to critically analyze how each piece of information gathered fits into the complicated puzzle of a comprehensive investigation.
