Exploring the Social Context of Instrumental and
Expressive Homicides: An Application of
Qualitative Comparative Analysis
Terance D. Miethe' and Kriss A. Drass'
Using data from the UCR's Supplementary Homicide Reports, the method of
qualitative comparative analysis (QCA) is used to examine whether instrumental
and expressive homicides are similar or unique in their social context (i.e., combi-
nations of offender, victim, and situational characteristics). Instrumental and
expressive homicides are found to have both common and unique social contexts,
but the vast majority of homicide incidents involve combinations of individual
and situational factors that are common in both general types of homicides.
Among subtypes of instrumental (like rape, prostitution, robbery murders) and
expressive homicides (like lovers' triangles, brawls, and arguments), there is wide
variability in their prevalence of unique and common components. After dis-
cussing these results, the paper concludes with illustrations of how QCA may be
used in other areas within criminology.
KEY   WORDS: homicide; qualitative comparative analysis; instrumental

1. INTRODUCTION
There are various ways to classify and distinguish types of criminal
homicide. State statutes distinguish between criminal and noncriminal homi-
cides, degrees of murders, and types of manslaughters. Law enforcement
agencies often categorize homicides according to the characteristics of the
offender (e.g., gang vs nongang), the victim (e.g., child murders, teen
violence, elderly victims), or its situational context or attributes (e.g., dom-
estic violence, stranger assaults, drive-by shootings, robbery-mur-
ders, road rage, or workplace homicides). Lawyers, social scientists,
and law enforcers also classify homicides in terms of their motive. Common
