Abstract

In this paper we describe an approach to assess the potentiality of a probabilistic system for indirect identification through DNA evidence. The aim is, before an identification is attempted, to provide, the expected performances of the system and help all the parts involved to judge if the system fits their requirements. The analysis provided considers the probabilities associated to the weight of evidence related to the case, also suggesting possible strategies to improve the system. A detailed case study is illustrated as well as some possible information theoretic measures able to summarize the information capabilities of the DNA marker employed in a specific indirect identification.
