Document Summary

Linkage analysis: identifying behavioural similarities between offenses that point to them being committed by the same perpetrator; Linkage analysis rests on the assumption of behavioural consistency; People show a degree of consistency but most evident when a person encounters psychologically similar situations; Different people will vary in the way they behave in the same situation; Behaviours vary in their degree of consistency; Behavioural consistency is proposed to increase with experience in an activity; Temporal period over which behaviour is observed can affect the degree of behavioural consistency. Recommend: recommend considering the frequency of similar homicide cases throughout a region; Use: use mo, ritualistic, and non-ritualistic behaviours to link cases; Determine: determine the central theme among linked cases; Use: for ritualistic behaviours, use the rarity of each factor as a first step in using each behaviour in the final signature determination; Combine: combine ritualistic and non-ritualistic features to determine the rarity of identifying a grouping characteristics as a signature element;
