Using PMCT of Individuals of Known Age to Test the Suchey–Brooks Method of Aging in Victoria,Australia

The estimation of an individual's age at death plays a critical role in the investigation of unidentified human remains. The Suchey–Brooks method, which involves the analysis of degenerative morphological changes in the pubic symphysis, is currently widely used to estimate age in adults. This study tested the applicability of the Suchey–Brooks method on a contemporary adult Australian (Victorian) subpopulation by observing three‐dimensional volume‐rendered postmortem computed tomographic (PMCT) reconstructions of the pubic symphysis of 204 individuals aged 15–100 years. Results showed the method was reliable for females (85% correct allocations) but not for males (67% correct allocations). It is therefore recommended that extreme caution be used when applying the Suchey–Brooks method for estimating age at death of an individual in this subpopulation from PMCT images. The results suggest further investigation into alternate age estimation methods is required.     

Improving court-appearance rates through court-date reminder phone calls

Without a defendant’s appearance in court, the adjudication of criminal charges cannot proceed. The low defendant court appearance rates of Lafayette Parish, Louisiana were identified as a high priority to address. A pilot project was implemented, in which, Lafayette Parish Sheriff’s Office (LPSO) Information Officers would call defendants approximately 5–9 days before their pretrial court appearance. This process began in September 2014. LPSO staff attempted to call all non-incarcerated or diverted defendants with known contact information. LPSO staff documented when calls were made and the type of response (spoke to defendant, left a voicemail, no answer, inoperable phone or spoke to friend or family member). Calls were made to defendants with court appearances in arraignment hearings, misdemeanor pretrial and trial, felony pretrial and traffic court. Court appearance rates for all court hearings increased from 48 to 62%.     

An Anthropological Examination of the Types of Skeletal Fractures Resulting from Fatal High (˃3 m) Free Falls,

Fatal falls from heights (?3 m) often result in blunt force trauma (BFT) to the skeleton. The fracture patterns that result from this BFT mechanism are well understood in forensic anthropology and forensic pathology; however, details of the specific types of fractures that result remain poorly documented. The aim of this study was to provide a detailed examination of the types of fractures that may result from fatal high falls. Fractures were recorded from 95 full‐body postmortem computed tomography scans of individuals known to have died from a high fall. Trauma was then analyzed taking into account the extrinsic and intrinsic variables known to influence a fall using multiple logistic regression. A total of 339 types of fractures were classified, of which 16 were significantly associated with this BFT mechanism. Classified fracture types will augment anthropological interpretations of the circumstances of death from BFT in cases of suspected high falls.     

Microwave-assisted extraction and differential scanning calorimetry in the chemical identification of sliming agents apprehended in the south region of Brazil

Over the past decades, consume of slimming agents considerably increased in several countries, including Brazil, due to weight-loss and stimulant properties. Since these drugs are controlled to prevent illicit and indiscriminate use, there is a parallel illegal market that uses the Internet and irregular pharmacies in order to distribute these formulations. Slimming agents produced by these illegal sources are known for being manufactured with little or none quality control resulting in uncertain and unknown formulations. For forensic purposes, apprehended pharmaceuticals have to undergo a process of chemical identification that can be difficult due to its complex matrix. In this sense, application of assisted energies in the extraction step such as microwave irradiation can be a promising method to increase the recuperation of the target molecules of the sample. Therefore, the aim of this research was to identify four slimming agents apprehended in Brazil by means of visual inspection, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry and Gas Chromatography – Mass Spectrometry. Moreover, the efficiency of solid-liquid extraction and microwave-assisted extraction was compared. It should be noted that our work was one of the few to use Differential Scanning Calorimetry and the application of microwave irradiation in the analysis of apprehended materials. Results showed that the majority of the samples was counterfeit being composed of one or several adulterants or contaminants. Initially, visual inspection resourcefully screened the slimming agents for possible signs of falsification, however it failed to detect fraudulent products that were very similar to veridical medicines. Sequentially, Fourier Transform Infrared Spectroscopy detected functional groups present in the samples while the presence or absence of the alleged active ingredients were successfully measured with Differential Scanning Calorimetry and, thus, providing a full chemical screening of the apprehended materials. Gas Chromatography- Mass Spectrometry confirmed the presence of adulterants such as caffeine, fluoxetine and phenolphthalein as well as contaminants such as sulfurol in the falsified samples. Finally, comparison of extraction procedures indicated that microwave-assisted extraction increased the recovery of compounds detected in chromatographic analysis to a greater extent than solid-liquid extraction.     

The effect of the presence and seating position of an interpreter on eliciting information and cues to deceit

The present experiment examined how the seating position of an interpreter during investigative interviews affects information elicitation and cues to deceit. A total of 60 native English speakers were interviewed in English and 200 non-native English speakers were interviewed in English (a non-native language) or through an interpreter who either sat next to the interviewer, behind the interviewee or interpreted via the telephone. Interviewees either lied or told the truth about a mock security meeting they watched. Interviewees who spoke in their native language provided more detail than interviewees who spoke in their native language through an interpreter or in a non-native language (English) without an interpreter. The latter groups did not differ. Additionally, the amount of detail differentiated truth tellers from liars in all conditions and interviewees found the presence of an interpreter to be a largely positive experience. The interpreter’s seating position had no effect on the findings.     

The experience of pregnancy and childbirth for unmarried mothers in London, 1760-1866

This article explores the experience of pregnancy and childbirth for unmarried mothers in the metropolis in the eighteenth and nineteenth centuries. It draws upon, in particular, the infanticide cases heard at the Old Bailey between 1760 and 1866. Many of the women in these records found themselves alone and afraid as they coped with the pregnancy and birth of their first child. A great deal is revealed about the birthing body: the ambiguity surrounding the identification of and signs of pregnancy, labour and delivery, the place of birth and the degree of privacy, and the nature of, and dangers associated with, solitary childbirth.     

Methyl 3-[3',4'-(methylenedioxy)phenyl]-2-methyl glycidate: an ecstasy precursor seized in Sydney, Australia

Five 44 gallon drums labeled as glycidyl methacrylate were seized by the Australian Customs Service and the Australian Federal Police at Port Botany, Sydney, Australia, in December 2004. Each drum contained a white, semisolid substance that was initially suspected to be 3,4-methylenedioxymethylamphetamine (MDMA). Gas chromatography-mass spectroscopy (GC/MS) analysis demonstrated that the material was neither glycidyl methacrylate nor MDMA. Because intelligence sources employed by federal agents indicated that this material was in some way connected to MDMA production, suspicion fell on the various MDMA precursor chemicals. Using a number of techniques including proton nuclear magnetic resonance spectroscopy ((1)H NMR), carbon nuclear magnetic resonance spectroscopy ((13)C NMR), GC/MS, infrared spectroscopy, and total synthesis, the unknown substance was eventually identified as methyl 3-[3',4'(methylenedioxy)phenyl]-2-methyl glycidate. The substance was also subjected to a published hydrolysis and decarboxylation procedure and gave a high yield of the MDMA precursor chemical, 3,4-methylenedioxyphenyl-2-propanone, thereby establishing this material as a "precursor to a precursor."     

Regulating Complex Contracting: A Socio‐legal Study of Decision‐Making Under EU and UK law

The article evaluates interview data on decision‐making under public procurement law using Halliday's analytical model on compliance with administrative law. In this study, unlike other studies on administrative compliance, the decisions faced by public bodies are not routine; they relate to the award of complex, high‐value contracts. Two contrasting decisions in the procurement process are discussed: the decision over the choice of procedure at the outset of the process, and the decision over the extent to which the public body should negotiate with the winning bidder towards the end of the process. The article considers the rationales behind decisions, and finds that, although public bodies are generally predisposed to comply, legal uncertainty means the relevance of commercial pressures and challenge risk impact heavily on approaches to compliance, even shaping understanding of what compliant behaviour actually is.
