Differentiating Sexual Violence: A Comparison of Sexual Homicide and
Rape
Abstract:
The present study sought to identify consistent patterns in the actions
of sexually violent offenders to determine whether sexual homicide and
rape reflect different behavioral emphasis of a single thematic model
of sexual assault. A sample of seventy-four (37 sexual homicide and
37 rape) solved cases of sexual violence from across England and Wales
were empirically compared over 17 variables that related directly to
the offender's behavior at the crime scene. Results of a non-metric
multi-dimensional scaling solution revealed three thematic styles of
interacting with the victim during a sexual assault (Exploit, Control,
and Violent). Further analysis indicated that offender-victim interactions
in sexual homicide and rape are predominantly distinguished by the degree
of violence, such that behaviors associated with each type of offense
were found to occur in two discrete areas along a single continuum.
The implications of these findings for elucidating a general framework
for understanding sexual violent interactions, and the possibility of
differentiating between offenses over a scale of increasing violence,
are discussed.
