FSC239Y5 Lecture Notes - Lecture 32: Geographic Profiling, Attractor, Ruin Theory
FSC239 Lecture 32:
• Hot spot mapping in law enforcement
• Tactical crime series analysis
• Geographic profiling analysis
o Not hotspot mapping
o Trying to establish, based on locations of crimes that have taken place, in a
crime series
▪ Determine likely profile/area where the offender lives or frequents
o Crime patterns
▪ Series of points on a map
o Crime series
▪ Next step after identifying pattern
▪ Whether crimes are related
• Committed by same person/group of people
▪ Case
• Map Guy
o Targeting pre-teen girls
o Over 20 cases unsolved
o Increase in frequency over time
o Reduce 300 km2 to 15 km2 area
▪ Either lives there or begins local hunt
▪ Does not predict where crime will happen
▪ Provides peak location of residence or significant routine space
o When people try to be random, they end up stabilizing the pattern
▪ Risk theory
▪ Travelling short distances vs long distances
▪ Rational choices
o Groups have an alpha
▪ Makes the decisions
▪ Identifier
o Cannot be used in all cases
▪ Has to be completely in series, or very close to
▪ Cannot to be a commuter/marauder
• Goes somewhere else to commit crime
▪ Target back law (cloth?)
• Offender can’t be found everywhere
• Crime generator/crime attractor
o Crime generator
▪ Parking lots
o Crime attractor
▪ Shady part of town
• Disqualify geographic profiling
• Targets must be found everywhere
