Abstract
Abstract In the USA, police statistics have shown a constant increase in violent crime, particularly murder and sexual assault, since the early 1960s. Studies associated with this problem have concentrated on serial crime — crime committed in a repetitive manner by the same perpetrator. The principal research projects have been conducted within the human sciences such as law, criminology, psychology and psychiatry, and have approached the problem by studying a posteriori the criminals and their behaviour. These studies have permitted a definition of the problem and the development of a classification system according to different typologies that can aid the investigator in solving cases of violent serial crime. In Switzerland, the only effort aimed at regrouping criminal information is limited to a central fingerprint identification system (AFIS) and the recording of randomly obtained information on personal ‘files’. These files contain only non-standardised and unverified information on private individuals, and are of only limited value to the criminal investigator. The systematic recording of crime-related information is principally aimed at establishing links between different criminal affairs occurring in different jurisdictions or between different affairs treated by different investigators within the same jurisdiction (state or canton, for example).
