Abstract.
We show how probabilistic expert systems can be used  to analyse  
forensic identification
problems involving DNA mixture traces using peak area information.  
This information can
be exploited to make inferences regarding the genetic profiles of  
unknown contributors to the
mixture, or for evaluating the evidential strength for a hypothesis  
that DNA from a particular
person is present in the mixture. We will also present an extension of  
the Bayesian network
for taking  account artifacts such as allelic dropout, stutter bands  
and silent alleles when
interpreting  DNA profiles from a single and from a pair of mixture  
traces.
We illustrate the use of the network on a published criminal casework  
example.

This is joint work with Robert Cowell and Steffen Lauritzen
