Recent research has highlighted the potential benefits of implementing criminal profiling in police investigations, to improve the efficacy of the identification of suspects. Due to the continuous increase in digital sexual offenses law enforcements are experiencing overwhelming amounts of cybercrime, necessitating a re-evaluation of investigative methods and resources. This thesis explores my preconception, that profiling of online offenders can strengthen and improve investigative methods, as well as potentially aid preventative methods, when dealing with cybercrime against children. Through two semi-structured expert interviews and research literature, this thesis aims to explore if the implementation of criminal profiling can increase efficacy in police investigative methods. The results indicate that the Trinity-approach to profiling enablesinvestigators to categorise the characteristics and patterns of offenders and victims, allowing for more effective and targeted strategies against online offenders. This ultimately enables law enforcement to better address cybercrime against children and to protect this vulnerable population. The thesis also acknowledges methodological limitations, due to a small sample size of interviews. This is, however, justified with the use of an in-depth case study method, emphasising the focus of gaining deeper insights, while also establishingthe validity of the results due to the hermeneutic approach.
