Differential diagnostics of stomach contents showing blue discoloration

A 42-year-old man evidently had died from an intoxication. On the basis of the findings at scene it was primarily assumed that the man had ingested a larger quantity of an ethylene glycol-containing antifreeze for suicidal purposes. The man was said to have had an alcohol problem and did not only consume drinking alcohol, but also other alcoholic liquids. At autopsy, a bluish liquid with an aromatic smell was found in the oesophagus and stomach. However, toxicological analyses did not furnish evidence of ethylene glycol--as expected--but a potentially fatal concentration of ethanol (blood alcohol concentration 4.01 per mille). The blue colour (patent blue C.I.42051) came from a liquid used in the wind-screen washer system in winter, which now contains ethanol (denatured with 2-butanone) instead of ethylene glycol. The results of the toxicological findings including the analysis of congener alcohols and the differential diagnostics of blue-coloured stomach contents are discussed.     

Overhearing the Planning of A Crime: Do Adults Outperform Children As Earwitnesses?

This study examined the reliability of earwitnesses using an ecologically realistic experimental set-up. A total of 282 participants, distributed over three age-groups (7–9 vs. 11–13 year olds vs. adults), were exposed to an unfamiliar voice for 40 seconds. After a two week delay, they were presented with a 7-voice lineup. Half of the participants were exposed to a target-present lineup (TP), and the other half to a target-absent lineup (TA). For both types of lineups the participants performed poorly. In the TP-condition only the 11–13-year olds (with 27% correct identifications) performed above chance level. Furthermore, in the TA-condition all age-groups showed a high willingness to make an identification (overall mean = 53%). For both groups of children, voice identification co-varied significantly with speaking rate and pitch level, as did pitch variation for the youngest children. Neither factor correlated significantly with the adults’ identifications.     

Vaginorectal impalement injury in a 2-year-old child--caused by sexual abuse or an accident?

Anogenital impalement injuries are rarely encountered in clinical or forensic practice. If seen in children and if incurred under suspect circumstances, sexual abuse must be considered in the differential diagnosis. Here we describe the case of a 2-year-old girl admitted to hospital with a vaginorectal impalement injury. According to the girl's parents, she had slipped in the bathroom and fallen onto the handle of an upright toilet bowl brush. Since a second slight anal injury was present, the parents' account appeared inconsistent. Therefore, physicians from the Institute of Legal Medicine were consulted to investigate the possibility of underlying sexual abuse. Because they could not rule out that the injuries could have been caused by sexual abuse, they recommended having the police immediately examine the site of the purported accident for evidence. The police and forensic investigations, however, verified the parents' account of an accidental injury. Thus, in this case, the initiation of a police inquiry, which is not compulsory in Germany even when sexual abuse is strongly suspected, led to the exoneration of the father.     

Interviewing to Detect Deception: When to Disclose the Evidence?

Research shows that there are few objective cues to deception. However, it may be possible to create such cues by strategic interviewing techniques. Strategic Use of Evidence (SUE) is one such technique. The basic premise of the SUE technique is that liars and truth tellers employ different counter-interrogation strategies, and that the evidence against the suspect can be used to exploit these differences in strategies. This study examined the effect of the timing of evidence disclosure (early vs. late vs. gradual) on verbal cues to deception. We predicted that late disclosure would be most effective in differentiating between liars and truth-tellers, and that cues to deception in the gradual disclosure condition would progressively disappear due to the suspects’ realization that evidence against them exists. That is, we expected that liars in the gradual presentation condition would become more consistent with the evidence over time. A sample of 86 undergraduate students went through a mock-terrorism paradigm (half innocent, half guilty), and were subsequently interviewed using one of three disclosure strategies: early, gradual, and late disclosure. We measured statement-evidence inconsistencies as cues to deception . Results supported our predictions in that cues to deception were most pronounced in the late disclosure condition. Contrary to our expectations, the results suggested that presenting the evidence gradually may put innocent suspects at a higher risk of misclassification as they seem to adopt a strategy that is more similar to guilty suspects.     

Blame attribution and guilt feelings in violent offenders

Offenders with high psychopathic traits and/or antisocial personality disorder (ASPD) are hypothesised to experience less guilt and less responsibility for their actions than offenders without these problems. These hypotheses were tested and partly substantiated. The study investigates blame attributions and guilt feeling using Gudjonsson Blame Attribution Inventory–Revised (GBAI-R) for 177 young male violent offenders. GBAI scores were compared to ASPD and psychopathy according to the Psychopathy Checklist–Revised. Results showed that individuals with ASPD and those with higher degrees of psychopathy tended to report significantly less guilt and higher degree of mental control than other subjects. Another finding was a weak relationship between ASPD, high scores on psychopathic traits and external attribution. We suggest these results might be explained by admitting poor mental control may be extra difficult for individuals belonging to either of these groups and that the external attribution items do not separate causal from moral responsibility.     

Beyond the Arab revolts: conceptualizing civil society in the Middle East and North Africa

How do we make sense of the potential role of civil society in the Middle East and North Africa (MENA) in bringing the region into a new era of reform and political participation? This article critically examines how the civil society landscape in the region has been conceptualized in the past and proposes a new typology of MENA civil society actors. I employ this typology in two cases – the revolutionary uprising in Egypt in 2011 and “evolutionary” long-term efforts to broaden the space for political participation in Lebanon. Comparing these two very different cases illustrates the utility of a typology of civil society actors (CSAs) that (a) emphasizes temporary coalitions between diverse actors; (b) highlights the both contentious and collaborative struggles through which political change actually happens; and (c) recognizes that different types of CSAs face different constraints and opportunities. I argue that employing such a typology can help structure comparison between disparate cases of civil society efforts for democratization and bring to the forefront issues of authenticity and legitimacy – challenges emanating not only from an oppressive state, but from within civil society itself.     

Challenges for teaching interaction skills for law students

Abstract

Are lawyers witty courtroom heroes or professionals working with and for people? Is law only universal judgements and afterthoughts or could it also be preventive and proactive individual planning and dialogue? The traditional legal education could be seen to have been based on the first assumptions. The course “Interaction skills for lawyers”, in the Faculty of Law at the University of Helsinki (Finland), evolves instead from the latter assumptions. In this article we relate our starting points in planning the course and evaluate our challenges and experiences in developing it.     

EXPERTISE AND DECISION‐MAKING IN THE LINKING OF CAR CRIME SERIES

The aim of the present study was to investigate whether experienced car crime investigators have special expertise in the linking of car crime and what characterises effective decision‐making in this context. Groups of experienced car crime investigators, experienced other investigators, novice participants, and naive participants attempted to link 10 series of three car crimes while thinking aloud. The results showed that experience had an effect on actual and self‐assessed linking accuracy but not on processing speed. Linking accuracy was also related to the use of a limited subset of case characteristics. Characteristics used in successful linking were included in a multidimensional scaling analysis which showed that these characteristics could be used to link the cases together also automatically. The implications of the findings for car crime investigation and for the creation of automated decision‐support systems were discussed.     

To act truthfully: Nonverbal behaviour and strategies during a police interrogation

Abstract

In an experiment, nonverbal indicators of deception in police interrogations of mock crimes were examined. Both vocal and nonvocal behaviours were scored. Thirty participants were subjected to long interrogations (over 9 minutes) conducted by 30 experienced police officers, asked to interrogate as they normally do. Although the liars reported being significantly more nervous, and found the task more strenuous than the truth tellers, no differences in the nonverbal behaviours scored were found. In an analysis of the strategies employed, both truth tellers and liars were found to try to not make excess movements. The principal verbal content strategy for the liars was to keep the story simple, and for truth tellers to keep the story real. The reasons why, in this demanding situation, the truth tellers and liars could not be distinguished by their nonverbal behaviour are discussed.
