2. Comparative Case Analysis
Q1: Can I link undetected crimes together?
Q2: I have an offender with a particular offending style. What other crimes is he good for?

3. Q1: Can I link undetected crimes to a common offender?
Burglaries

4. Structural Analysis of Behaviours
Posed (42)

5. Behavioural similarity of crimes

6. Identify crime series
All the same offender

7. Q2: I have an offender with a particular offending style
Q2: I have an offender with a particular offending style. What other crimes is he/she good for?
Burglaries

8. Posed & distraction?
Burglaries

9. Posed & distraction
Crime series

10. Suspect Prioritisation
Who dunnit?
Geography AND Behaviour to prioritise suspects

11. Geography
Prioritises offenders by the location of their (home) base(s)
iOPS does this with Dragnet
Geographical ‘profiling’ system
Developed at CIP
Integrated within iOPS

12. Principles of Dragnet Offenders tend commit crimes close to home
As distance from home to crime increases
Probability of committing the crime decreases
Distance decay

15. Our Example
Known offenders?

16. X = Prioritised offenders
Our example
X = Prioritised offenders
= Known offenders
= Crimes in series
