BackgroundSerial murder in clinics and care homes have gained attention more than once in recent years. The strong yet quickly fading public outrage has not yet led to well-founded professional and health-political engagement with the topic. With few systematic studies conducted, knowledge about perpetrator-related and environment-related risk factors in the day-to-day context of healthcare is sparse.MethodsCourt cases of serial murder in clinics and care homes in Germany, Austria, and Switzerland that were concluded with a final verdict by February 2022 were investigated. Research materials consisted of court documents and observations made during the trials. The cases were evaluated with regard to the victims, crime scenes, methods of killing, perpetrators, and perpetrator motives. 12 serial murders involving 17 perpetrators were included in this study.ResultsPerpetrator-specific early warning signs included a pronounced insecurity in combination with a striving for prestige and power, which were accompanied by a loss of empathy. Reactions of the colleagues and supervisors of the perpetrators in the immediate professional environment included misjudgement, concern about one's own disadvantages, feared damage to the reputation of the institution, and insufficient willingness to clarify the situation. As a result, many initial murders went unsuspected and unreported so that the frequency of the criminal activity and the number of victims increased over time.ConclusionMore information about serial murder in clinics and care homes is necessary. Research efforts are needed to better assess the prevalence of such crimes and to develop appropriate preventive measures. Circumstances that enable such acts, risk factors, perpetrator profiles, and early-stage countermeasures must be comprehensively addressed in the context of education, training and further education.The Author(s).
