PURPOSE
The duration of time that the serial offender remains free in the community to commit murders may be seen as a direct measure of their longevity; a sign of their success. The aim of this study is to predict the duration of the serial homicide series by examining the factors that contribute to the length of time a serial murderer is able to remain free of police detection.
Methods
Generalized estimating equations with a negative binomial link function were used to examine factors predicting the duration of series in a sample of 1258 serial murder cases.
Results
Results showed that offenders' criminal history, race (i.e., White and Hispanic), and victims of minority backgrounds significantly predicted longer duration in their murder series. A combination of multiple killing methods and atypical methods also predicted longer murder series, while the moving of the victim's body predicted shorter duration in the series.
Conclusions
This study builds upon the serial homicide literature, particularly the duration of the series.
RESULTS from this study help inform investigative efforts in serial homicide cases.
