Evidence, Sexual Assaults, and Case Outcomes: Understanding the Role of Sexual Assault Kits, Non-Forensic Evidence, and Case Characteristics, 2015-2017

This project examined the role of sexual assault medical forensic exams (sexual assault kits) and other case characteristics in achieving investigative and prosecutorial outcomes in sexual assault cases. The study team conducted comprehensive reviews of over 500 sexual assault cases based on reports to police to identify evidence and case characteristics as they progress through case processing. Using statistical models, the study team predicted case outcomes using a variety of case, suspect, and victim characteristics, with a focus on the role of sexual assault exams and kits. Additionally, the study team interviewed key stakeholders in each site to supplement the case-level information, including law enforcement, prosecutors, representatives from victim service agencies, and sexual assault nurse examiners.
