Can Victim, Offender, and Situational Characteristics Differentiate Between Lethal and Non-Lethal Incidents of Intimate Partner Violence Occurring Among Adults?

Abstract

This study investigates risk factors that predict the likelihood of homicide as a result of intimate partner violence. Using a subsample of the 2011 National Incident-Based Reporting System (NIBRS) data, we estimate binary logistic regression models comparing homicide by intimate partners to aggravated assault by intimate partners. Several victim characteristics (race, age), offender characteristics (age, race, relationship with victim), and situational characteristics (weapon use, offender alcohol use) differentiated homicide incidents from aggravated assault incidents. The findings provide evidence that characteristics of victims, offenders, and events contribute to the likelihood that intimate partner violence will escalate to homicide.
