Prior literature shows that although marginalised populations are at a high risk of severe violence and homicide, research has focused on their offenders as if they constituted a homogeneous group. On the basis of a sample of 213 sex offenders who targeted marginalised individuals (i.e., sex trade worker, homeless individual, and severe drug user), we investigate the different pathways that these offenders take both prior to and during the commission of their crimes. Results of 2‐step cluster analysis regarding the offender's development, criminal history, crime context, and modus operandi revealed 3 distinct pathways of the offending process. The coercive pathway was characterised by the amount of violence used against the victim. The explosive pathway was defined by offenders who were in a state of rage at the time of the offence. Finally, offenders in the situational pathway committed their crimes out of opportunity and used very little violence. Differences between pathways were investigated with regard to characteristics of the index offence.
