Applications of Social Network Media in Medicolegal Death Investigation

With the increased popularity of online social networking services (SNS) such as Facebook, LinkedIn, Twitter, and Google+, we propose that a wealth of new resources is available for medicolegal death investigation. Recognizing this potential, we identified cases in which social media had been useful in the past in our office and asked our investigative staff to consider using social media in current cases. These cases provided illustrative examples for this primer regarding how information from SNS was used in death investigations in our office. Information gleaned from online social media aided in establishing preliminary identification of a decedent, locating next‐of‐kin, investigating the circumstances of death as relevant to the manner of death, corroborating eyewitness accounts, and providing information relevant to time of death. Potential pitfalls were identified, such as shared accounts or online impostors. SNS proved useful to the medicolegal death investigator and medical examiner, so long as their limitations were recognized.     

DNA‐Based Identification of Forensically Important Lucilia (Diptera: Calliphoridae) in the Continental United States*

Abstract: Correct species identification is critical when dipteran larvae are used for inference of the postmortem interval. To facilitate DNA‐based identification of forensically important flies of the genus Lucilia in the continental United States, we develop a vouchered reference collection and DNA sequence database. A total of 122 specimens were collected for nine of the 10 species of Lucilia reported to occur in the continental United States. Using the polymerase chain reaction and DNA sequencing, data were obtained for an 1100‐bp region of the mitochondrial gene encoding cytochrome oxidase I (COI). We consider a species suitable for DNA‐based identification if it is exclusively monophyletic in >95% of bootstrap pseudoreplicate phylogenetic analyses. Seven of the nine species meet that criterion. Two species (Lucilia coeruleiviridis and Lucilia mexicana) share COI sequence and cannot be distinguished using our reference database. We conclude that DNA‐based identification is likely to be successful for the other seven species.     

State‐Sponsored Homophobia and the Denial of the Right of Assembly in Central and Eastern Europe: The “Boomerang” and the “Ricochet” between European Organizations and Civil Society to Uphold Human Rights

State‐sponsored homophobia emerged in certain Central and Eastern European states in the past decade, with the denial of the right of assembly for gay pride marches. However, more recently there has been progress in the recognition of the fundamental democratic right of assembly. What accounts for this progress in fulfilling commitments enshrined in the European human rights treaties? This article proposes that the response of European organizations, in particular the Council of Europe and the European Union, as well as human rights nongovernmental organizations working in collaboration with local civil society organizations, have been critical to this progress. Previous literature has described a “boomerang” effect, in which aggrieved citizens use transnational activist networks to publicize human rights violations and put pressure on governments to fulfill their international legal commitments. To understand the functioning and effectiveness of the “boomerang” we introduce the concept of the “ricochet”—a process in which various institutions and civil society rapidly exchange information as well as political and legal argumentation. We posit that the ricochet is an integral process in the development of a European consensus on the human rights recognized by the European Court of Human Rights. Four cases have been selected for empirical analysis: Poland, Latvia, Serbia, and Russia. In analyzing the ricochet of information and argumentation between institutions and civil society, we find the consensus has been framed around the right of assembly, instead of the more contested area of human rights and sexual orientation.     

“What works” with mentally disordered offenders

Treatment and rehabilitation of mentally disordered offenders has traditionally been a function of high security hospitals, but is increasingly based in community settings. Evidence for the effectiveness of psychological interventions remains scarce, and for secure hospitals, is limited to demonstrations of short-term effects using a conventional range of behavioural and cognitive–behavioural procedures. Some findings support the use of directive community programmes in meeting the needs of public safety and improved reintegration of the individual. Long-term services are required, and more complex psychological contributions are needed to meet the multiple needs of this client group.     

Providing eyewitnesses with initial retrieval support: what works at immediate and subsequent recall?

The effect of retrieval support on eyewitness recall was investigated in two experiments. Based on the outshining hypothesis, Experiment 1 tested whether retrieval support enhances witness performance (compared to free recall) especially when witnessing conditions are suboptimal (e.g., because witnesses were distracted during the crime). Eighty-eight participants watched a videotaped crime with either full or divided attention and subsequently received retrieval support with the Self-Administered Interview© (SAI) or completed a free recall (FR). One week later (Time 2 – T2) all participants completed a second FR. Unexpectedly, retrieval support did not lead to better memory performance than FR under divided attention conditions, suggesting that retrieval support is not effective to overcome adverse effects of divided attention. Moreover, presence of retrieval support at Time 1 (T1) had no effect on memory performance at T2. Experiment 2 (N = 81) tested the hypothesis that these T2-results were due to a reporting issue undermining the memory-preserving effect of T1-retrieval support by manipulating retrieval support (SAI vs. FR) at T1 and T2. As expected, T1-retrieval support led to increased accuracy at T2. Thus, the beneficial value of T1-retrieval support seems greatest with high-quality T2-interviews. Interviewers should consider this when planning a subsequent interview.     

Eyewitness identification procedures for multiple perpetrator crimes: a survey of police in Sweden,Belgium, and the Netherlands

ABSTRACT

A considerable proportion of crimes involve multiple perpetrators. Yet, little is known about how police officers construct, administer, and record eyewitness identification procedures for multiple suspects. An online survey of law enforcement agents in Sweden, Belgium, and the Netherlands (N?=?51) was conducted to obtain an initial understanding of police perceptions of prevalence and characteristics of multiple perpetrator crimes, and to examine identification procedure practices given the little to no guidance provided for police. Practice converged when it came to the use of sequential, photographic lineups, but diverged between and within countries on whether or not suspects of multiple perpetrator crimes should be placed in separate lineups. Results specifically highlight contextual cuing as one critical area for future research in identification for multiple perpetrator crimes (i.e. placing multiple suspects in the same lineup or asking eyewitnesses to look for a specific suspect).     

‘I'm a photographer,not a terrorist’: the use of photography to detect deception

When planning large-scale incidents or bombing campaigns, terrorists often conduct reconnaissance research to identify key targets. This may include taking photographs of potential target locations. Identifying an effective real-time method to distinguish between genuine photographers and those with more sinister intent may be beneficial for law enforcement and security agencies. Participants took photographs in a public place with a genuine intent (truth tellers) or sinister intent (liars). After taking these photographs, the participants were approached by an undercover interviewer (a mime artist) who asked them whether he could see the photographs. Later, the participants discussed their photographs in a formal interview. First, liars were less cooperative in their interaction with the undercover interviewer than truth tellers. Second, in the formal interview, liars mentioned some security features that appeared in the photographs more than truth tellers. The findings suggest that ‘using photographs to detect deception’ is a subject that could prove important to explore to benefit forensic and counter-terrorist practice.     

Two heads are better than one? How to effectively use two interviewers to elicit cues to deception

Background. We examined the effect of a second interviewer's demeanour on cues to deception. We predicted that a supportive demeanour would be the most beneficial for eliciting verbal cues to deceit, as it would encourage truth tellers, but not liars, to say more. In addition, we examined the extent to which interviewees deliberately made eye contact with the interviewers. Liars take their credibility less for granted than truth tellers, and therefore have a greater drive to be convincing. Liars are thus more likely to monitor the interviewer to determine if the interviewer appears to believe them. Method. Participants appeared before two interviewers: the first asked all the questions and the second remained silent. The second interviewer exhibited either a supportive, neutral, or a suspicious demeanour. Results. Truth tellers provided significantly more detail than liars, but only in the supportive second interviewer condition. The effect of a second interviewer's demeanour on detail was perhaps remarkable given that the interviewees hardly looked at the second interviewer (less than 10% of the time). Liars displayed more deliberate eye contact (with the first interviewer) than truth tellers did. Conclusions. A supportive second interviewer has a positive effect on interviewing. We discuss this finding in the wider contexts of investigative interviewing and interviewing to detect deception.     

Image construction versus empirical evaluations: automobile safety

The present study expands upon earlier work examining advertising as it relates to the construction of safety-related images in the automobile industry. Comparisons are made between automaker portrayal of vehicle safety in magazine advertising and their real-world safety-related performances. Such an analysis enables suggestions regarding, whether or not, the extent to which particular automakers demonstrate a misleading concern for safety and potentially produce false advertisements that violate the standards of law. In this sense, misleading claims related to automobile safety could be considered corporate deviance, particularly in relation to false advertising practices. This paper examines safety and vehicle marketing, a noted gap in recent literature, by looking at three magazine publications over the course of five?years and comparing the marketing strategies and assessing the extent to which automaker crash test evaluations correspond with their socially constructed, safety-based image. Our findings suggest that automakers are largely accurate in their advertising practices with regard to promoting and supporting safety claims.
