Criticisms of Typologies
- Overlap of types (thrill, lust, power/control)
- Typologies were generated from case files
- Cannot explain changing motives
- Lack of empirical scrutiny or analyses by external individuals
Testing Holmes & Holmes Typology (Canter & Wentink, 2004)
- 100 serial killers, coded killing #3
- Two assumptions
o Assumed that crime scene characteristics should cluster together if different types exist
o Each type needs to have characteristics that are clearly distinct from those of other types
