Geographical profiling of serial offenders Prof Craig Jackson As serial murder offending spaces evolve, can geographical profiling help investigations? School of Social Sciences Faculty of Business, Law & Social Sciences
Criminal / Offender profiling does not work • Geo profiling has high potential to catch serial offenders • Consider relationship between work and offending • The role and context of driving, remoteness & isolation • How do offenders ‘move through their worlds’? • Don’t explore murderers’ minds – explore their environment Overview
The age of transit and movement Jacques Lantier and "Lison" in La Bete Humaine, Emile Zola (1890)
Enables trolling / stalking Fantasy space - anchor point Covert trial runs Extends Offending space Valid reason for solitude / alibi Gives authority / makes respectable Reduces likelihood of victim being related to offender Crosses police boundaries Structural approach: Vehicle use

Prof. Stuart Kind • UK govt scientist & academic • Home Office Central Research Establishment • Accidentally invented geo profiling • Realised maps of serial crimes could predict offender base(s) • Before term "offender profiling" even used • Led to "Lawrence Byford" report The Pioneer of Geographic Profiling
Principles of Geographic Profiling In a few hours, using techniques he learned as a Royal Air Force wartime navigator, Dr Kind mapped the dates and times of the killings, trying to determine the centre of gravity of the attacks. Kind realised the killer needed darkness and was trying to mislead the police as to his operational base
Principles of Geographic Profiling • Dr Kind knew the Ripper had to return to his home as soon as possible to avoid capture near the crime scene. • He deduced that the earlier in the evening an attack happened, the further away from "home" the killer was. • Attacks very late at night happened close to his base, so he could return home quickly at a decent hour.”
