    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. 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

    13. Source, Professor Canter, iOPS presentation, September 2004

    14. Our Example Known offenders?

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

    16. Prioritisation table

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

    18. MO Matching Behaviours in crimes Behaviours of known offenders climb sharp smoke defecate

    19. Prioritisation table

    20. Social Network Analysis

    21. 3. Prioritise suspects using Geo-behavioural profiling iOPS: An interactive Geo-Behavioural Profiling System 2. Identify offence series 1. M.O. 'heat map' 4. Social Network Analysis 5. Linked Offenders?
