Research Context

​The aim of this research is to identify how police forces in the UK currently review their unsolved murders.

An exploration of the decisions made during these reviews, and how they impact the progression of cases, is explored alongside the factors which can influence a detective's final outcome(s) for the case. A further element of this research is to determine how cases are reviewed and progressed when they do not have any forensic evidence available to facilitate a thorough review in line with the ACPO's guidance.

Research Methodology

The research will utilise:

  • ​Surveys for the police, legal professionals and forensic scientists

  • Interviews with policing organisations in the UK and US

  • Decision-Board Analysis with detectives of differing ranks, and with differing levels of experience.

Interim reports and publications
