About this Lecture


In this lecture, we think about the organised and disorganised typologies in the context of murderers, focusing in particular on: (i) the early development of these two typologies by Ressler et al. in 1986; (ii) examples of an organised and a disorganised crime scene, with their features being attributed, in part, to the intelligence levels of each respective criminal; (iii) the typical traits associated with an organised and disorganised offenders respectively; (iv) the development of the mixed offenders category, which is often relevant for pre-planned attacks involving a chaotic crime scene, and for murders involving more than one killer.


In this course, Professor Ciarán O’Keeffe (Buckinghamshire New University) explores offender profiling. In the first lecture, we think about the top down and bottom up approaches to profiling, and review a range of definitions of offender profiling. In the second lecture, we think about the FBI’s organised and disorganised crime scene and criminal typologies. Next, we think about the investigative psychology approach as an alternative to the ‘FBI approach’. In the fourth and final lecture, we think about geographic profiling and its origins in John Snow’s ‘cholera map’ of London.
