A Bayesian Approach to the Problem of Interpreting Glass Evidence in Forensic Science Casework

Abstract A new approach is described to the problem of interpreting the evidential value of glass fragments found on the clothing of a person who is suspected of having committed a crime. The problem is described in a formal sense and a brief review is given of previous papers which have been written on the problem. It is then shown how the Bayesian argument can be applied. Numerical examples are given, based on data abstracted from various sources.
