A comparison of graphical methods using the case of the murder of Meredith Kercher as an example

Year: 2025
Type: article
Abstract: We compare three graphical methods for displaying evidence in a legal case: Wigmore Charts, Bayesian Networks, and Chain Event Graphs. We find that these methods are aimed at three distinct audiences, respectively, lawyers, forensic scientists and the police. The methods are illustrated using part of the evidence in the case of the murder of Meredith Kercher. More specifically, we focus on representing the list of propositions, evidence, testimony, and facts given in the first trial against Raffaele Sollecito and Amanda Knox with these graphical methodologies.
