One of the current trends in the study of criminal profiling consists of developing theoretical
and methodological typologies to o er information of operational use in police investigations.
The objective of this work was to verify the validity of the instrumental/expressive model, so as
to establish homicide typologies based on modus operandi relationships, characteristics of the
victims, and characteristics of perpetrators. The sample consisted of 448 homicide cases registered
in the database of the Homicide Revision Project of the O ce of Coordination and Studies of the
Spanish Secretary of State and Security. Through multidimensional scaling and cluster analysis,
three expressive homicide subtypes were identified (expressive-impulsive, expressive-distancing,
and expressive-family), as well as two instrumental homicide subtypes (instrumental-opportunist
and instrumental-gratification). The expressive homicide typologies accounted for almost 95% of
all of the studied cases, and most of the homicides occurring in Spain were found to take place
between individuals who know one another (friends, family members, intimate couples/ex-couples).
The findings from this study suggest that the instrumental/expressive model may be a useful
framework for understanding the psychological processes underlying homicides, based on the study
of relationships between the crime and aggressor characteristics, which may be very helpful in the prioritization of suspects
