Injury evidence and biological evidence gained from forensic medical examinations of victims can provide evidence about the crime as well as the means of linking a suspect to the crime. Evidence from a forensic medical examination can include genital and non-genital injuries, biological evidence (including sperm or semen, blood, and amylase, an enzyme of saliva), and a DNA profile that can often be derived from the biological evidence. This DNA can be matched to a potential suspect, matched to another investigation in the FBI’s Combined DNA Index System (CODIS), or matched to a convicted offender in CODIS. Injury evidence can be used to establish a victim’s lack of consent and could lead to physical assault charges. 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.
