This project explored the use and impact of injury evidence and biological evidence through a study of the role of these forms of evidence in prosecuting sexual assault in an urban district attorney's office in a metropolitan area in the eastern United States. The research questions addressed in this summary overview were as follows: How frequent were different forms of injury evidence and biological evidence in the sample? Is the presence of injury evidence and biological evidence correlated with the presence of other forms of evidence?Which types of cases and case circumstances are more likely to yield injury evidence and biological evidence? Do the presence of injury evidence and biological evidence predict criminal justice outcomes, taking into account the effects of other predictors? In what ways do prosecutors use injury evidence and biological evidence and what is their appraisal of their impact on case outcomes?
