Forensics: Bottom Up Approach

    Cards (8)

    • Bottom Up offender profiling
      • Doesn't use pre-established typology but develops a profile
      • Two Hallmarks are investigative psychology and geographical profiling
    • Investigative psychology
      Each crime is recorded on a database to develop hypotheses about likely characteristics
    • Geographical profiling
      Suggests each offender has an operational base, which can be inferred by mapping locations of previous crimes
    • Marauders
      Crimes close to home
    • Commuters
      Crimes opposite to home
    • Offender profiling doesn't always lead to correct identification (only 3% success rate)
    • Offender profiling is more scientific and less reductionist
    • There is evidence supporting geographical profiling
