The challenge of identification following the tragedy of the Solar Temple (Cheiry/Salvan, Switzerland)

On October 5, 1994, 48 members of the Sect of the Solar Temple were found dead at two different locations in Switzerland: 23 victims in Cheiry and 25 victims in Salvan. Our Institute was commissioned to solve the forensic problems presented by this tragedy. Our goals were to establish the time of death, determine its causes, help elucidate the surrounding circumstances and identify the victims. This work presented us with the following challenges

• this catastrophe was of an ‘open’ type: there were no lists of ‘passengers’;

• the victims were of five different nationalities and many had just arrived in Switzerland to participate in this event;

• family ties were very complex within the group;

• half of the victims were burned and sometimes charred;

• the exceptionally intense media coverage of the story put a lot of pressure on the investigators and our Institute.

In spite of these difficulties, all the victims were positively identified within 1 month. In the present report, we describe the steps realized to progress in our work. A special section describes our relationship with the journalists and their invaluable help in our investigations. The importance of being prepared for such an event is discussed.     

A study of the interrelationships of several validity scales used in police selection

Validity scale data have received attention recently as providing valuable information about potential problematic police officer candidates. In this study, validity scale data from a number of selection instruments were obtained using 42 state police officer candidates. The scale used were the MMPI-2 L scale, the MMPI-2 K scale, the PAI Positive Impression Scale (PIM), the PAI Defensiveness Index (DI), the IPI Guardedness scale, the Hilson Life Adjustment Profile Lack of Candor scale, and the Inwald Survey 2 Denial of Shortcomings scale. Intercorrelations among the scales were developed and a factor analysis was performed. Factor analysis revealed two factors to be present. One is associated with the Hilson scales and is appropriately named guardedness or defensiveness. The other is associated with the MMPI-2 K scale and the PAI scales and is appropriately named social desirability. The MMPI-2 L scale loaded significantly on both factors and seemed to be the most general of the validity scales in terms of its characteristics. Implications of these analyses for police selection are discussed.     

Three Faces of Constituency Campaigns in Mixed-Member Electoral Systems. Parties and Candidates in Germany, 2005–13

Constituency campaigns are multidimensional and complex: parties and candidates are deeply entangled, and, at least in mixed-member electoral systems, local constituency campaigns are embedded within national party campaigns. Recent discussions have focused on aspects of campaign change in European democracies, especially disentanglement in terms of individualisation, personalisation, and/or localisation. This study contributes to the discussion both conceptually and empirically. Conceptually, three dimensions (‘faces’) of constituency campaigns are differentiated: organisational partyness, vertical integration, and communicative personalisation. This threefold differentiation allows for a more precise analysis of campaign patterns by differentiating party–candidate (organisation, communication) and intra-party (vertical integration) aspects. Constituency campaigns in the 2005, 2009, and 2013 German federal elections are empirically examined. The analysis explains why candidates decide for one or another campaign pattern. These three faces are empirically distinct as well. Furthermore, we argue that parties remain vital for the organisation of campaigns despite a decline in centralisation. Addressing the communicative face, the analysis shows that candidate-related issues are important, but a mix of party- and candidate-related communication gains importance.     

Evaluation of high performance liquid chromatography (HPLC), enzyme linked immunosorbent assay (ELISA) and particle concentration fluorescence immunoassay (PCFIA) methods for the screening, quantitation and pharmacokinetic study of furosemide in horses

Equine plasma and urine samples were analyzed by using a high-performance liquid chromatography (HPLC), enzyme-linked immunosorbent assay (ELISA) and particle concentration fluorescence assay (PCFIA). Although ELISA and PCFIA were rapid, simple and sensitive for the screening of furosemide, they did not give reproducible quantitative results. The HPLC method, which required relatively longer analysis time, provided simple and reproducible quantitative analysis of furosemide in plasma and urine. The performance of the three methods was compared for the quantitation of furosemide in plasma obtained from thoroughbred mares dosed intravenously with furosemide (500 micrograms/kg (n = 7) and 1.0 mg/kg (n = 5)). Although the plasma furosemide profiles determined by ELISA, PCFIA and HPLC were similar, ELISA and PCFIA methods exhibited considerable variation in values. At high furosemide concentrations, the PCFIA method gave better quantitative values than ELISA. However, at trace furosemide concentrations the PCFIA method gave false positive values which were not confirmed by HPLC or ELISA. The pharmacokinetic values obtained from the HPLC data and the pharmacokinetic values obtained previously from the gas chromatographic data were comparable. The data obtained by ELISA and PCFIA were not suitable for the pharmacokinetic calculations.     

Selective detection of cytomegalovirus by in situ hybridization

In two SIDS autopsy cases, in situ hybridization with biotin-labeled DNA probes was used to demonstrate a specific cytomegalovirus (CMV) infection in paraffin-embedded tissue sections. This technique represents a rapid, specific, and highly sensitive tool for the detection of CMV infections and is recommended for routine examination in other suspected viral infections, particularly in cases connected with SIDS.     

A novel approach to the visualisation of heat-induced structural change in bone.

A new approach to visualising heat-induced change in bone was attempted. This was an attempt to counter the serious limitations of existing analytical methods yet still allow for the examination of subtle changes that occur due to burning. A new form of Magnetic Resonance Imaging was deemed to fulfil this remit. Preliminary tests were performed and proved successful in creating clear, well-defined images of progressive heat-induced structural changes in bone. The implications for improving our understanding of heat-induced change, and therefore our methods of human identification, are significant.
