OFFENDER PROFILING:
TOP-DOWN APPROACH
,The American approach
● Also known as the typology approach
● The top-down approach to profiling is originated in the US
● FBI’s Behavioural Science Unit drew upon data gathered from in-depth interviews
with 36 sexually motivated serial killer including Ted Bundy & Charles Manson
● Match what’s known about the crime & the offender to a pre-existing template that
the FBI developed. Murderers & rapists are classified in one of two categories
[organised or disorganised] on the basis of the evidence & this classification
informs the subsequent police investigation
● Organised & disorganised distinction is based on the idea that serious offenders
have certain ‘ways of working’ [often referred to as their modus operandi] & these
generally correlate with a particular set of social & psychological characteristics
that relate to the individual

, CONSTRUCTING AN FBI PROFILE
There are 4 main stages in the construction of an FBI profile:
1. Data assimilation - the profiler reviews the evidence [crime scene photos, pathology
reports, etc]
2. Crime scene classification - organised or disorganised
3. Crime reconstruction - hypotheses in terms of sequence of events, behaviour of the victim,
etc
4. Profile generation - hypothesis related to the likely offender e.g demographic background,
physical characteristics, behaviour, etc
