Forensic Medical Results and Law Enforcement Actions Following Sexual Assault: A Comparison of Child, Adolescent and Adult Cases

Cases were randomly sampled from a statewide database of medical reports on sexual assault examinations conducted in hospital emergency departments, including only cases reported to law enforcement (N = 563). Data were combined from a medical report database, from coding of medical documentation and crime laboratory reports, and from case data provided by law enforcement. The study found that rates for both younger and older adolescent victims and adult victims were comparable, with no statistically significant differences on the variables of penetration, perpetrator use of force, non-genital and genital injuries, presence of biological evidence, generating assailant DNA profiles, DNA match to suspect, hits in the FBI's DNA database, and law enforcement "unfounding" (i.e., determining allegations to be false or baseless). Child victims were significantly less likely to have a non-genital injury, and their cases were significantly more likely to be founded by law enforcement. Arrests were significantly more likely when victims were under the age of consent. Despite significant differences by victim age, similarity between adolescent and adult cases was substantial. Both younger and older adolescents may be at higher risk of physical violence during sexual assault than previously recognized, so they may require more medical services in response systems.
