Unpredictable Behavior Under the Influence of “Magic Mushrooms”: A Case Report and Review of the Literature

Fatalities implicating psychedelic mushrooms are not a common clinical situation in everyday forensic medicine. Despite classification as an illegal drug in many countries, psilocybin mushrooms have the reputation of being safe. We report the case of a young man who jumped from a second story balcony under the influence of psilocybin mushrooms. The psilocin assay was performed by gas chromatography coupled to an electron‐impact ionization time‐of‐flight detector (GC‐EI‐TOF) after solid‐phase extraction. Total psilocin was quantified in peripheral and cardiac blood as 60 and 67 ng/mL, respectively, and in urine (2230 ng/mL), bile (3102 ng/mL), and vitreous humor (57 ng/mL). This case report and review of literature highlights the danger of psilocybin mushrooms. Isolated use of psilocybin mushrooms by a regular consumer without psychiatric history, even under “safe” circumstances, can lead to a fatal outcome.     

Implementation and Optimization of the Sodium‐Rhodizonate Method for Chemographic Shooting Distance Estimation

In shooting incident investigations where it is important to estimate the shooting distance, the sodium‐rhodizonate coloring method has been used for the visualization of GSR patterns extensively. This publication describes the optimization of this method by the use of a heated press for the transfer of GSR traces on garments, as well as variation of a number of other important process parameters. Our final aim for this project was to prepare a formal validation of the coloring method as prerequisite for its inclusion into the scope of ISO17025‐certified methods in the GSR Laboratory. A number of important factors and process parameters were identified, such as buffer composition and pH, type of textile used as a substrate and resolution of the documentation of the results. Results were tested using a synthetic proficiency test. Our optimized method has been found to be a very effective technique for visualization of macroscopic GSR traces.

Severity of neurocognitive impairment in women who have experienced intimate partner violence in Spain

This study examines neuropsychological impairment in women who have experienced intimate partner violence using DSM 5 criteria for mild and severe cognitive impairment. A total of 108 females in Spain were included in one of three groups: psychological abuse (n = 24), physical and psychological abuse (n = 45), and no-abuse (n = 39). There were differences between the control and IPV groups in attention and executive functioning. Furthermore, approximately 25% of women experiencing IPV suffer mild neuropsychological alterations and 5% severe, mostly in memory and executive function domains. This evidence supports the growth in research that suggests psychological violence on its own to be as strongly related to poor health outcomes as physical violence in intimate partner relationships.     

Not guilty by reason of insanity: clinical and judicial profile of medium and high security patients in Belgium

Under Belgian law, offenders deemed to lack criminal responsibility because of insanity receive mandated treatment under the internment law. Population profiles of these forensic patients (‘internees’) are, however, very scarce. In this study, we analysed the demographic, clinical and judicial profile of a large sample of Belgian internees admitted to a secure setting. In addition, differences between internees admitted to a medium versus a high security setting were investigated. Belgian internees were characterised by a large number of personality disorders and a low number of first offenders. Comparative analyses showed substantial differences between the high and medium security settings, with a marked proportion of the forensic patients in high security having committed a sexual offence. Contrary to expectations, more predictors for length of stay were found in the medium security subsample, while admission periods were significantly longer in the high security subsample.     

Secondary transfer of organic gunshot residues: Empirical data to assist the evaluation of three scenarios

The present study aimed at providing data to assess the secondary transfer of organic gunshot residues (OGSR). Three scenarios were evaluated in controlled conditions, namely displacing a firearm from point A to point B, a simple handshake and an arrest involving handcuffing on the ground. Specimens were collected from the firearm, the hands of the shooter and the non-shooter undergoing the secondary transfer in order to compare the amounts detected.Secondary transfer was observed for the three scenarios, but to a different extent. It was found that displacing a firearm resulted in secondary transfer in <50% of the experiments. The firearm also had an influence, as contrary to the pistol, no secondary OGSR were detected using the revolver. Shaking the hand of the shooter also transferred OGSR to the non-shooter's hand. In that case, the amount of OGSR was generally higher on the shooter than on the non-shooter. Finally, the largest secondary transfer was observed after the arrest with handcuffing with positive results in all cases using the pistol. In that scenario, the amounts on the shooter and the non-shooter were in the same range.This study highlights that the secondary transfer must be taken into account in the interpretation of OGSR. Indeed, an individual's hands might be contaminated by handling a firearm or having physical contact with a shooter.     

Abolition and pedagogy: reflections on teaching a course on alternatives to punishment,state repression and social control

Abolitionism is an important, but often overlooked, theoretical and political alternative to the failings and injustices of the penal system and other forms of social control. While many have documented different approaches to abolitionist strategy, few have explored the work that is done sensitizing individuals to abolitionism, including in university settings. Through an analysis of student journal entries, this study discusses how students enrolled in a mandatory abolition course engaged with the viability of, and barriers to, a world without prisons, punishment and other forms of control. By looking at abolition as a threshold concept, we consider how students negotiate the concept of abolition as a radical justice alternative. As the journal entries showed, while students were able to understand the basic tenets of abolition, many remained in a liminal state between the existing system and the unknown landscape of abolition, and could not see its viability or possibility as a radical alternative. We conclude that other learning strategies may have been helpful in moving student through such a ‘dangerous’ concept. Further research on sensitising individuals to abolition is needed given the current proliferation and intensification of penal and carceral institutions today.     

Preliminary results of an investigation on postmortem variations in human skeletal mass of buried bones

Extreme fragmentation can complicate the inventory of human skeletal remains. In such cases, skeletal mass can provide information regarding skeleton completeness and the minimum number of individuals. For that purpose, several references for skeletal mass can be used to establish comparisons and draw inferences regarding those parameters. However, little is known about the feasibility of establishing comparisons between inherently different materials, as is the case of curated reference skeletal collections and human remains recovered from forensic and archaeological settings. The objective of this paper was to investigate the effect of inhumation, weather and heat exposure on the skeletal mass of two different bone types. This was investigated on a sample of 30 human bone fragments (14 trabecular bones and 16 compact bones) that was experimentally buried for two years after being submitted to one of four different heat treatments (left unburned; 500?°C; 900?°C; 1000?°C). Bones were exhumed periodically to assess time-related mass variation. Skeletal mass varied substantially, decreasing and increasing in accordance to the interchanging dry and wet seasons. However, trends were not the same for the two bone types and the four temperature thresholds. The reason for this appears to be related to water absorption and to the differential heat-induced changes in bone microporosity, volume, and composition. Our results suggest that mass comparisons against published references should be performed only after the skeletal remains have been preemptively dried from exogenous water.
