5 of 14
What was Canter's aim?
To test the reliability of organised/disorganised classification of killers in offender profiling.
6 of 14
Describe the procedure of Canter's top-down typology research
Content analysis of 100 cases of serial killers from the USA. 3rd crime committed by each serial killer was analysed using The Crime Classification Manual as either organised or disorganised.
7 of 14
What were the results found about organised/disorganised?
Twice as many disorganised as organised crime-scenes were identified.
8 of 14
How were the bodies found?
In 70% of cases, the body was concealed, in 75% of the cases, sexual activity occurred.
9 of 14
What did further analysis do?
Further analysis failed to reveal any significant differences between organised and disorganised variables.
10 of 14
What did Canter conclude?
Concluded that instead of there being a distinction between 2 types of serial murder, all of the crimes had to have an organised element to them as they hadn't been caught after 3 killings.
11 of 14

Concluded it would be better to look at personality variables
12 of 14

No evidence for the organised/disorganised typology.
13 of 14
