There appears to be some hesitation within the forensic biology community to formally evaluate and report on findings given activity level propositions. This hesitance in part stems from concerns about the lack of relevant data on the dynamics of biological traces and doubt about the relevance of such expert opinions to the trier of fact. At the Netherlands Forensic Institute formal evaluative opinions on the probability of case findings given propositions at the activity level are provided since 2013, if requested by a mandating authority. In this study we share the results from a retrospective analysis of 74 of such requests. We explore which party initiates requests, the types of cases that are submitted, the sources of data being used to assign probabilities to DNA transfer, persistence, prevalence and recovery (TPPR) events, the conclusions that were drawn by the scientists, and how the conclusions were used by the courts. This retrospective analysis of cases demonstrates that published sources of data are generally available and can be used to address DNA TPPR events in most cases, although significant gaps still remain. The study furthermore shows that reporting on forensic biology findings given activity level propositions has been generally accepted by the district and appeal courts, as well as the other parties in the criminal justice system in the Netherlands.

Objective: The majority of parents with a disabled child experience chronic sorrow, characterized by recurrent feelings of grief and loss related to their child’s disability. There is a significant lack of research on parents’ lived experiences of chronic sorrow, which limits our ability to understand parents’ needs and provide proper support. Design: Interpretative Phenomenological Analysis (IPA) was conducted based on in-depth interviews with six parents of severely disabled children. Results: In the literature on chronic sorrow, an important aspect has been consistently overlooked: the particular position of being a parent, experiencing an awareness of being ultimately responsible for their children. The analysis revealed how this awareness, experienced as a deeply felt ethical commitment, unconditional, largely in isolation, and without a limit in time, shaped the experience of chronic sorrow. Because of this awareness, the parents experienced themselves facing a Herculean task of navigating their intricate motions while struggling to maintain their ability to function. Conclusions: By revealing the importance of considering the unique parental position, the study enriches the concept of chronic sorrow, simultaneously offering insights into what it means to be a parent of a disabled child. These insights can improve care professionals’ responsiveness to parental needs.

Residential burglaries often go unsolved, as collected DNA traces and fingermarks frequently originate from residents rather than the offender. It is therefore important to know how to target sampling locations that specifically relate to the burglary event. However, data that aid in assessing the likelihood of a burglar touching certain surfaces, and, consequently leaving trace evidence, is unavailable. Instead, forensic examiners rely primarily on their personal experience and expertise to determine where burglary-related traces are most likely to be found.The current study aims to identify specific areas that are contacted during different types of interactions with points of entry. An experiment was conducted at a Dutch music festival, where participants simulated both a legitimate and burglary scenario. Using paint, the points of contact between the participants’ hands and the experimental set-up were recorded. The contact locations of all participants were combined using heatmaps to reveal the patterns of contact. We found that different burglary methods lead to distinct contact patterns, indicating specific areas where traces are most likely to be deposited. Our findings can support forensic examiners in making evidence-based decisions during search strategies in burglary investigations.
