Rapists' behaviour: a three aspect model as a basis for analysis and the identification of serial crime.
In this paper it is proposed that the behaviour of an offender during a sexual assault can be considered as consisting of three main groupings or 'aspects'. These have been termed 'Modus Operandi', 'Sexual and Personal Gratification' and 'Attitude and Intimacy'. Although an oversimplification, such a model facilitates a preliminary description of the offender which can be of direct assistance to an investigating officer. Various factors affect the consistency and variability of behaviour and the model has formed a basis for the development of a concept as to which behaviours might be the more useful for identifying linked offences. This more systematic approach to the investigative and intelligence processes is reliant on a victim's statement containing very detailed information about the offender's actions, together with a record of as much of his speech as can be recollected. The material required is described using the model and the text is illustrated with case examples. Instances are quoted of the possible inferences and their relevance to the investigation of sexual offences.
