Top Down Approach Flashcards
Offender profiling
- predicts and profiles characteristics of an offender
- creates a hypotheses of who the offender might be
FBI top down approach
- Interviewed 36 sexually motivated murderers
- concluded that data could be characterised into organised or disorganised murderers
Organised and Disorganised offenders
- each category has certain characteristics
- in future situations crime scenes could be matched
Organised offender
- evidence crime was planned
- victim is deliberately targeted
- control is maintained
- little evidence
- high IQ
- in a professional occupation
- has a family
- sexually competent
disorganised offender
- little evidence of planning
- offence is spontaneous
- crime scene left messy
- little control
- low IQ
- unskilled
- unemployed
- sexual dysfunction
- live alone
Four stages of constructing an FBI profile
- Data assimilation (review of evidence)
- crime scene classification (organised/ disorganised)
- crime reconstruction (hypotheses in terms of sequence of events/ behaviour of victim)
- profile generation (hypotheses of likely offender)
Evaluation
+ Research support - serial killers studied - seem to be a subset of features such as high intelligence and
sexual competence of serial killers - has validity
+ wider application - applied to burglary leading to an 85% rise in solved cases in the US
- Flawed evidence - small interview sample, similar kind of offender, non-standard questions
