While sexual assault is a crime that frequently occurs, public perceptions tend to greatly differ from the reality of the act. Sexual assault is the most underreported crime in the United States. This is perhaps due to the negative stigma that surrounds victims of sexual assault and the presence of rape myths in society today. Perceptions of sexual assault can vary depending on the relationship between the victim and the offender and the presence of physical evidence, if any, that was collected at the scene of the crime. This study uses data on sex crimes reported to the Los Angeles Police Department and the Los Angeles County Sheriff’s Department in 2008, to address the following research questions: How are sexual assault cases prosecuted when the offender is a stranger vs. non-stranger to the victim? Does physical evidence play a role in the charging decisions of stranger vs. non-stranger cases? Data are analyzed using logistic and multinomial regression. Findings show that there is little to no significance among victim-offender relationship and charging decision, but this varies among different evidence types. Implications of this study and areas of future research are discussed.
