A Statistical Approach to Crime Linkage

Abstract: The object of this paper is to develop a statistical approach to criminal linkage analysis that discovers and groups crime events that share a common offender and prioritizes suspects for further investigation. Bayes factors are used to describe the strength of evidence that two crimes are linked. Using concepts from agglomerative hierarchical clustering, the Bayes factors for crime pairs are combined to provide similarity measures for comparing two crime series. This facilitates crime series clustering, crime… Show more

“…In general, these models achieved statistically larger AUCs than the tree‐based models, which is perhaps unsurprising given the problems of overfitting that are sometimes associated with classification tree models (e.g., Liu et al, ; Thomas et al, ; Tonkin, Woodhams, et al, ). Although, it is important to note that regression and probabilistic models do not always outperform tree‐based models in terms of discrimination performance (Porter, ).…”

“…Within this research, several different statistical methods have been tested to determine whether they have the potential to underpin BCL decision-support tools. These include logistic regression (e.g., Bennell & Jones, 2005;Burrell, Bull, & Bond, 2012;Melnyk, Bennell, Gauthier, & Gauthier, 2011;Tonkin, Grant, & Bond, 2008;Woodhams & Labuschagne, 2012;Woodhams & Toye, 2007), classification tree analysis (e.g., Tonkin, Woodhams, Bull, Bond, & Santtila, 2012), and Bayesian analysis (e.g., Kringen, 2014;Porter, 2014;Salo et al, 2013;Winter et al, 2013). Many of these studies have, however, only tested a single statistical method and have not compared different approaches.…”

“…One way to do this is to identify cases in which there is a higher probability of a near repeat crime (Garnier et al, 2018;Moreto et al, 2014;Piza & Carter, 2018), and then devote more detective resources to those events (or prevent them from being triaged). Another may be to use other automated detection processes to identify if a particular crime is linked to other crimes (Chohlas-Wood & Levine, 2019;Porter, 2016). Again, those criminal events within a linked chain should then get higher priority from detectives, as those individuals have established a prior history that suggests they will commit a future crime.…”
