This study aims to describe the views of forensic psychiatric patients' parents, and especially how they feel about the patient's offense. The data analyzed was collected by interviews with forensic psychiatric patients' parents and analyzed by inductive content analysis. The findings suggest that the offense committed has a significant effect on the lives of parents of forensic psychiatric patients and in many ways these people felt like a marginalized group even though they were frequently a major resource for their child who had been taken into forensic psychiatric care. The parents of a forensic psychiatric patient have a prominent role in the life of the patient and this role and the parents' coping should also be supported by the forensic psychiatric treatment system.
