abstract: Details are given of the sexual assaults dealt with by this laboratory, with particular mention of the increasing number of rape cases submitted each year. The contribution of a forensic biologist to the investigation of alleged rapes is summarized. The laboratory's sexual assault index is explained using examples of three series of linked rapes recognized by this method. The uses and limitations of the ABO grouping of semen are briefly mentioned and an example given showing how the male's ABO group may be ascertained even in the absence of semen.
