Offender profiling- Bottom up Flashcards
Bottom up
Profilers work up from evidence collected from the crime scene to develop hypotheses about the likely characteristics, motivations and social background of the offender
What country did the bottom up approach originate from
UK
Who did carried out work for the bottom up approach
Police
What was the Polices research into the bottom up approach
Profile is data driven and emerges as the investigator engages in deeper and more rigorous scrutiny of the details of the offence
What are the two parts to the bottom up approach
- Investigative psychology
- Geographical profiling
Investigative psychology
A form of bottom-up profiling the matches details from the crime scene with statistical analysis of a typical offender behaviour patterns based on psychological theory
Interpersonal coherence
Crime scene behaviour reflects everyday behaviour
Eg. Helliwell saying gorgeous girl and gorgeous boy at crime and everyday life
Geographical profiling
A form of bottom-up profiling based on the principle of spatial consistency- that and offenders operational base and possible future offences are revealed by the geographical location of the previous crimes
Crime mapping
Utilising the information about the location of crime scenes to make inferences about the home base of an offender
Spatial consistency
An offenders operational base and possible future offences are revealed by the geographical location of their previous crimes
Canters circle theory
Created due to the assumption that the pattern of offending forms a circle around the offenders home
Centre of gravity
Offenders home
Jeopardy surface
Where they are next likely to commit a crime
What are the two models of offender behaviour
- Marauder
- Commuter
Marauder
