Aim: Test relibailty organised/ disorganised typologies
Method: Content analysis using 100 cases to found out if the features hypothesised belong to each typology would be consistently and distincly differed. The cases came from published accounts of serial murders in the use and were cross-checked with court reports and officers. The third crime committed by each serial killer in each series was analysed for research. The crime classification manual was used to classify the crimes as organised or disorganised
Findings:
- Twice as many disorganised as organised crime scene action were identified
- Only two crimes-scene behaviours co-ourred in the orgainsed typologies which where the body was concelaed in 70% of cases and sexual activity occured in 75% of cases
- Only sex acts and vaginal **** occur in more than 2/3 of disorganised cases
- Further stastical analysis failed to seperate the two sets of variables
Conclusion: Canter concludes that instead of there being distinction between two types of serial murder, al such crimes will have an organised element to them, as we might expect from the fact the killers were not caught after three killings
