Resumen:
According to the Federal Bureau of Investigation (FBI) of the United
States of America (USA), the serial killing is defined as the murder of two or more
victims by the same offender in separate events. Despite the low frequency of serial
killers, each of which may be responsible for a large number of deaths. Data from
this study may help detect earlier the serial killer, and prevent the extent of their
crimes. OBJECTIVE: To verify the association between ritualized serial crimes and
typologies based on motivation and organization of the crime scene. METHODS: We
performed a cross-sectional study. The population consisted of serial killers
cataloged in Radford / FGCU Serial Killer Database (Radford / FGCU SKDB) who
committed their first murder in the 80s of the last century. The subjects were
classified according to the motivation for the homicide and organizing of the murder.
Variables were cross-matched with the presence of ritualistic behaviors during the
crime. Data were tabulated in Microsoft Excel® 2013 and statistical analysis
performed using the IBM SPSS software in the version 23.0. Two crosstabs were
settled up, between motivation or the organization of the crime and the presence of
ritualistic behaviors, with chi-square test of independence for the two subsamples
and 5% of significance level. RESULTS: The typology based on the motivation for
murder could be set to 619 subjects. Four types - pleasure, financial gain,
anger/hatred and multiple reasons accounted for over 80% of the subjects. It was
confirmed that there is statistically significant difference between the frequency with
which types of murderers in series ritualize their crimes. Comparing the groups, the
killers motivated by pleasure and disorganized group had the highest percentage in
the practice of rituals. CONCLUSION: There were statistically significant differences
in the frequency of performance of rituals. The sample was concentrated in three
specific types of motivation for the crime: pleasure, anger and financial gain. The
ones who kill for pleasure, in turn, presented the highest prevalence of ritual
practices. As for organized or disorganized types, the latter was more associated
with the practice of ritual actions than the first.
