The exploration of the psychological states, traits, and characteristics of non-organised crime homicide offenders in the commissioning of homicide

The psychological state, traits, and characteristics of non-organised crime homicide offenders (NOCHO) and their body disposal methods is not a subject that has historically been explored. This research seeks to identify the specific states, traits and characteristics exhibited by NOCHO’s and predict body disposal methods, in order to aid criminal investigators and profilers faced with disorganised crime scenes. This research adopts a Rapid Evidence Assessment methodology to analyse the existing scientific evidence base between 2002 to 2022, providing a contemporary understanding of this area. Findings revealed that NOCHO’s are often delusional, impulsive, socially inadequate, unable to maintain interpersonal relationships, have higher rates of personality disorders, have criminal histories, are withdrawn, and use drugs or alcohol. Findings made throughout this series of studies will contribute to knowledge within this field.
