Drug consumption estimates are of relevance because of public health effects as well as associated criminal activities. Wastewater analysis of drug residues enables the estimation of drug consumption and drug markets. Short-term and long-term trends of cocaine, MDMA (ecstasy), amphetamine (speed) and …

Narcissism is a personality construct with grandiose, and vulnerable aspects, that are interconnected through antagonistic characteristics. While antagonism is strongly related to antisocial behavior, the role of narcissism remains underexplored in offender rehabilitation practice. Research in non-forensic …

Bayesian networks have shown to be a useful tool for the evaluation of forensic findings given activity level propositions. In this paper, we demonstrate how case specific experiments can be used to assign probabilities to the states of the nodes of a Bayesian network for the evaluation of fingermarks …

A previous paper published in this journal proposed a model for evaluating the location of fingermarks on two-dimensional items (de Ronde, van Aken, de Puit and de Poot (2019)). In this paper, we apply the proposed model to a dataset consisting of letters to test whether the activity of writing a letter …

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 …

Traces of condom lubricants in fingerprints can be valuable information in cases of sexual assault. Ideally, not only confirmation of the presence of the condom but also determination of the type of condom brand used can be retrieved. Previous studies have shown to be able to retrieve information about …

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 evaluation of fingermarks given activity level …

Highlights •Crime scene investigations are accompanied by cognitive challenges. •Introducing technologies at crime scenes requires research into the human factor. •Mobile technologies can impede the investigation without studying the impact.

In this paper, we describe a promising method to evaluate the location of fingermarks on two-dimensional objects, which provides valuable information for the evaluation of fingermarks at activity level. For this purpose, an experiment with pillowcases was conducted at the Dutch music festival Lowlands, …

This study examined if a macro-, meso-, and micro outcome measurement instrument that constitutes the evaluation stage of a Dutch forensic psychiatric outcome monitor, the Hoeven Outcome Monitor (HOM), can provide a first step towards a more evidence based groundwork in forensic mental health. General, …
