The boundaries within a cold case review: review type, terms of reference and prioritisation scales
Authors: Bennett Kirsty

PurposeThe reviews of cold case homicides are infrequently referenced within either procedural guides or scholarly outputs. However, boundaries for the review are imperative to ascertain the most productive use of resources, aligned with the case’s chance of eventual resolution. The purpose of the study is to identify the boundaries established by police forces within England and Wales for their reviews of cold cases. Due to the lack of guidance, forces have created their own methods which may result in ineffective review processes and strategies. Therefore, this study sought to elucidate the boundaries of the review process through 13 semi-structured interviews with cold case detectives and a seven-month observation period (analysed simultaneously using an inductive Thematic Analysis), the following boundaries were identified before the review commences: the Terms of Reference (which provide a framework for the review based on live homicide review criteria), the identification of the review type (either a full or thematic review) and justification of the case’s prioritisation. This study provides initial evidence that there is an interconnectedness of procedures underpinning the reviews of cold cases, with the Terms of Reference dictating the type of review to be conducted, which is subsequently influenced by the case’s prioritisation. This study provides an important insight into the boundaries of reviews, and recognises the challenges for their implementation, attributed primarily to available resources and the number of cases that a force is responsible for. Important recommendations are proposed for the ongoing practice of cold case reviews to provide areas of evaluation and improved practice.Design/methodology/approachThe reviews of cold case homicides are infrequently referenced within either procedural guides or scholarly outputs.
