In spite of the problems associated with the development of a statisti
cal approach in specific case analysis, the potential of two statistic
al methods, logistic regression and Bayesian belief networks, has been
investigated and found encouraging in the context of a database relat
ing to child murders with a sexual connotation. Continual collaboratio
n between statisticians and detectives would be needed in the collecti
on of the data, the choice and construction of the models, and the int
erpretation of the results.
