DESCRIPTION:<br><span>co-authors J de Koeijer\, J de Zoete and B Kokshoorn
 &nbsp\;<br></span><span><br>The Netherlands Forensic Institute is currentl
 y exploring the use of Bayesian networks in their forensic casework. We id
 entified a number of different ways that networks can be used\, e.g.\, as 
 a probability calculator\, as an exploratory tool for complex problems and
  as a reasoning tool. In this presentation we focus on the latter and disc
 uss a recent case in which Bayesian networks were used in this way. The ca
 se concerned a series of six different robberies in which several DNA matc
 hes with a suspect were found on &ldquo\;movable objects&rdquo\; in each c
 ase. We were asked to assess the evidential value of the combined DNA evid
 ence. Bayesian networks proved to be very valuable to assist in our reason
 ing and in busting a few important DNA myths that are common in the legal 
 domain. We chose not to report the networks themselves but only the reason
 ing\, and explain why.&nbsp\;</span>
