- Top Down
- AO1
- American approach
- used as result of FBI work of info gathered from interviews with 36 sexually motivated serial killers
- Typology approach - match what is known about crime to pre-existing template - murderers and rapists either organised or disorganised
- Organised
- Planned crime before hand
- Victim deliberately targeted due to killers type
- High degree of control and operate with surgical precision
- Little evidence left and tend to be above average IQ, in a skilled professional job and are socially and sexually competent, often having families.
- Disorganised
- Little evidence of planning, often spontaneous
- Crime scene reflects impulse - body often left behind and little to no control
- Lower than average IQ, unskilled or unemployed, history of sexual dysfunction and failed relationships
- Constructing FBI profile
- Data assimilation - evidence reviewed
- Crime scene classified - organised or disorganised
- Crime recronstruction
- Profile generation - hypotheses made to likely offender
- American approach
- AO3
- Only applies to particular crimes

- Alison et al - old fashioned view of beh as see behaviour as being driven by stable disposition rather than constantly changing external factors
- Poor validity when identifying possible suspects or trying to predict next move

- Small sample size
- Only 184 police officers asked, low population validity

- developed on interviews with 36 serial killers
- Too small and an unrepresentative sample to base typology profile on that could influence police investigation
