Studies on geographical profiling have typically focused on crimes with physical crime sites. This study focused on crimes with no physical crimes sites (i.e. no physical contact occurred between the victim and the offender). A single offender made obscene phone calls to 86 children during the years 1999-2000 in the south of Sweden. The locations in which obscene phone calls were received were analysed in a geographical profiling system (Dragnet) to see whether it could provide a map that showed the most likely area the offender would reside in. The purpose of this study was to explore whether geographical software such as Dragnet can be used by investigators of crimes with no physical crime locations. The result showed that the offender in this case had his home close to the region assigned the highest probability of containing home or base, which indicates that Dragnet can provide maps that can narrow down the search areas for the police in cases without physical crime locations.

Considerable emphasis is placed on the importance of building rapport when interviewing witnesses and suspects. Despite the abundant literature on the working alliance in therapeutic settings, however, few studies have addressed the topic of 'rapport' in investigative interviewing. Conceptual analysis revealed a number of similarities between the two constructs. This finding suggests the possible benefits of using the theoretical therapeutic construct and operationalisation of the working alliance in order to gain insight into the dynamics of investigative interviewing in a police context. The present study examines the perceptions of witnesses and suspects regarding the working alliance in actual interviews. It also considers their perceptions of interviewing style, which is another key element in investigative interviewing. In addition, the study investigates the relationship between the working alliance and the interview style. Self-report questionnaires completed by investigators and interviewees showed significant differences between investigators and suspects and between witnesses and suspects with regard to perceptions of interview style and the working alliance during interviews. The results showed perceived interview style to be a predictor of the working alliance.
