"How old is this fingermark?" This question is relatively often raised in trials when suspects admit that they have left their fingermarks on a crime scene but allege that the contact occurred at a time different to that of the crime and for legitimate reasons. The first part of this article highlighted the current lack of consensus among the answers given to this question by the experts. It was also emphasised that no methodology has been validated and accepted by the forensic community so far. This is why this second part proposes a formal and pragmatic framework to approach the fingermark dating question using current research about aging kinetics of lipid compounds found in fingermark residue. This framework allows identifying which type of information the scientist would be able to bring so far to investigators and/or Justice about fingermark dating, in which conditions and what developments are still required.
