Forensic reports use various types of conclusions, such as a categorical (CAT) conclusion or a likelihood ratio (LR). In order to correctly assess the evidence, users of forensic reports need to understand the conclusion and its evidential strength. The aim of this paper is to study the interpretation of the evidential strength of forensic conclusi...
Article
Fysieke en digitale sporen worden vaak gebruikt in strafzaken om misdrijven te bewijzen. Fysieke sporen worden meestal geanalyseerd om daarmee de bron van het spoor te achterhalen, maar forensisch onderzoekers toetsen de laatste jaren vaker hypothesen op activiteitniveau aan de hand van fysieke sporen. Op dit moment wordt nog weinig aandacht bestee...

Full-text available
Fingerprints are widely used in forensic science for individualization purposes. However, not every fingermark found at a crime scene is suitable for comparison, for instance due to distortion of ridge detail, or when the reference fingerprint is not in the database. To still retrieve information from these fingermarks, several studies have been in...
Article
Fingermarks are highly relevant in criminal investigations for individualization purposes. In some cases, the question in court changes from 'Who is the source of the fingermarks?' to 'How did the fingermark end up on the surface?'. In this paper, we explore the evaluation of fingermarks given activity level propositions by using Bayesian networks....
Article
In de afgelopen decennia hebben technologische ontwikkelingen veel veranderingen teweeggebracht in de forensische opsporingspraktijk en is ook het onderwijs voor de forensisch technische onderzoekers ingrijpend veranderd. Forensische technieken en processen ontwikkelen zich zeer snel, evenals de technologie in de omgeving waarin forensisch onderzoe...

In the present study, how crime scene investigators are informed before going to a crime scene was investigated. In order to gain more insight in the flow of information from emergency call to crime scene, semi-structured interviews were conducted in three different police regions with six crime scene investigators, six forensic team leaders, and s...
Article
Full-text available
Crime scenes can always be explained in multiple ways. Traces alone do not provide enough information to infer a whole series of events that has taken place; they only provide clues for these inferences. CSIs need additional information to be able to interpret observed traces. In the near future, a new source of information that could help to inter...
Article
New technologies will allow Crime Scene Investigators (CSIs) in the near future to analyse traces at the crime scene and receive identification information while still conducting the investigation. These developments could have considerable effects on the way an investigation is conducted. CSIs may start reasoning based on possible database-matches...
