Abstract |
The use of DNA profiles in forensic identification problems are common procedure nowadays. It was in England, in 1995, where the first DNA profiles database was built. It gave rise to new challenges concerning the forensic identification. Here it is intended to exemplify how to use the analysis of DNA profiles to solve the problem of simple maternity search. For this aim it is necessary to make use of a probabilistic expert system (PES), in this case an object-oriented Bayesian network (OOBN). |

Abstract |
The use of biological information in crime scene identification problems is becoming more and more common. In this work, a crime scene is presented and used to exemplify the use of Bayesian networks, to analyse the information contained in a mixture DNA trace, referring to a crime in which there are two victims’ and two suspect’s involved. It is also made some discussion about the hypotheses to be considered in order to make them compatible with the possible information extracted from the mixture trace that constitutes the evidence. |
