Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.
