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.

这项研究调查了风险因素，这些风险因素预测了亲密伴侣暴力行为导致凶杀的可能性。我们使用2011年国家基于事件的报告系统（NIBRS）数据的子样本，估计了将亲密伴侣的凶杀与亲密伴侣的严重攻击进行比较的二元逻辑回归模型。几种受害者特征（种族，年龄），罪犯特征（年龄，种族，与受害者的关系）和情境特征（使用武器，罪犯饮酒）将凶杀事件与严重攻击事件区分开。研究结果提供了证据，证明受害者，罪犯和事件的特征导致亲密伴侣暴力升级为凶杀的可能性。
