Sex workers are commonly claimed to be at heightened risk of fatal victimization. Although prior research indicates that the dynamics of sex worker homicides resemble sexual homicides more than nonsexual homicides, little is known about how these types of homicides compare in terms of offending patterns. This study considers a sample of 2,851 single-victim, single-offender homicide cases extracted from a 37-year (1976–2012) US Supplementary Homicide Reports database, and compares the offender, victim, and offender characteristics of 243 sex worker homicides (189 males and 54 females) with those of 2608 sexual homicides (2474 males and 134 females). The findings suggest that the offender, victim, and offense characteristics of general, male-offender, and female-offender sex worker homicides are essentially different from the characteristics of sexual homicides. Logistic regressions further indicate that most offender, victim, and offense characteristics on the occurrence of general and male-offender sex worker homicides were significantly associated with the perpetration of general and male-offender sex worker homicides, with reference to sexual homicides. These findings offer insights relevant to the prioritization of criminal investigative practices.

性工作者凶杀案和性凶杀案：犯罪者、受害者和犯罪特征的比较研究

性工作者通常被声称面临更高的致命受害风险。尽管先前的研究表明，性工作者凶杀案的动态比非性凶杀案更像性凶杀案，但人们对这些类型的凶杀案在犯罪模式方面的比较知之甚少。本研究考虑了从 37 年（1976 年至 2012 年）美国补充凶杀报告数据库中提取的 2,851 起单一受害者、单一犯罪者凶杀案件的样本，并比较了 243 起性工作者凶杀案的犯罪者、受害者和犯罪者特征（男 189 人，女 54 人），性凶杀案 2608 人（男 2474 人，女 134 人）。调查结果表明，一般男性罪犯的罪犯、受害者和犯罪特征，和女犯性工作者杀人案与性杀人案的特征有本质区别。逻辑回归进一步表明，在一般性和男性性犯罪者性工作者凶杀案的发生中，大多数罪犯、受害者和犯罪特征与一般性和男性性性工作者性工作者凶杀案的实施显着相关，参考性凶杀案。这些发现提供了与刑事调查实践的优先顺序相关的见解。
