Money Laundering and Terrorism Financing Risks of Prepaid Cards Instruments?

Advances in information and communication technologies (ICT) have had, and will continue to have, wide-ranging influences on how the banking and finance industry operates. Making payments and transmitting money electronically or online are increasingly popular. An increased dependence on global electronic payment systems and the ability to move large amounts of money expeditiously across different jurisdiction, however, expose both payment processing companies and consumers to an evolving spectrum of threats such as fraud and money laundering. This article considers ways in which prepaid cards can be exploited by organised criminals and terrorists to launder their illicit proceeds of crime, and to transfer money anonymously and instantaneously over the globe for use by terrorist organisations. Risks identified in this article include recruiting card mules (e.g. international students) to purchase prepaid cards, and the mailing or shipping of prepaid cards out of the country without regulators being aware. To minimise risks of abuse by organised criminals and terrorists, legislation will need to adapt to deal with threats that organised criminals and terrorists seek to exploit. Future directions for research in relation to prepaid cards are also identified.

Voltammetric determination of cocaine in confiscated samples using a cobalt hexacyanoferrate film-modified electrode

In this work, a fast, non destructive voltammetric method for cocaine detection in acetonitrile medium using a platinum disk electrode chemically modified with cobalt-hexacyanoferrate (CoHCFe) film is described. The deposition of CoHCFe film at platinum disk (working electrode) was carried out in aqueous solution containing NaClO₄ at 0.1 mol L⁻¹ as supporting electrolite. Stability studies of the film and subsequent voltammetric analysis of cocaine were made in acetonitrile medium with NaClO₄ at 0.1 mol L⁻¹ as supporting electrolite. A reversible interaction between cocaine and CoHCFe at the film produces a proportional decrease of original peak current, due to the formation of a complex between cocaine and cobalt íons, with subsequent partial passivation of the film surface, being the intensity of current decrease used as analytical signal for cocaine. A linear dependence of cocaine detection was carried out in the range from 2.4 × 10⁻⁴ to 1.5 × 10⁻³ mol L⁻¹, with a linear correlation coefficient of 0.994 and a detection limit of 1.4 × 10⁻⁴ mol L⁻¹. The analysis of confiscated samples by the proposed method indicated cocaine levels from 37% to 95% (m/m) and these results were validated by comparison to HPLC technique, being obtained good correlation between both methods.     

Increased sensitivity for amplified STR alleles on capillary sequencers with BigDye XTerminator™

Free fluorescent dyes from PCR primers or amplification products can interfere with the interpretation of STR alleles in an electropherograph especially when the profiles have a low signal intensity. These artefacts can be removed by using a simple procedure based on BigDye^® XTerminator™. This procedure requires limited amounts of PCR product, allows to do several loadings on a capillary sequencer starting from the same purified PCR product and also increases the sensitivity for detection of less amplified loci.     

The Use of Radio-Frequency Identification Tags for Labeling Dentures—Scanning Properties

Abstract:  The inclusion of radio-frequency identification (RFID)-tags within dental prostheses has been suggested as means of effectively labeling such devices and permitting rapid and reliable identification of the wearer. Previous studies have suggested that patients will accept denture labeling and recognize the need for such systems. However, they demand systems that are aesthetic, durable, and secure. One concern over the use of RFID-tags is that they could be scanned by third parties without the patient's knowledge. This study categorizes the scanning patterns of RFID-tags both in vitro and in vivo to provide data for patients for the consent process and for forensic dentists to ensure that they are scanning prostheses optimally. The results demonstrate that the RFID chips can only be read when the interrogator is in close proximity to the denture and thus should alleviate any concerns over privacy issues. However, evidence obtained from both the literature and experiments suggests that authorities must agree upon a unified standard for chip and reader specifications and protocols in order to avoid cases in which RFID-tags may fail to be read by an incompatible reader.     

Study of Short- and Long-Term Storage of Teeth and Its Influence on DNA

Abstract:  DNA degradation can interfere with the resolution of forensic cases. Allelic dropout often reduces the opportunity for adequate comparisons between degraded and reference samples. This study analyzed DNA degradation in 24 extracted teeth after storage at room temperature for 0, 2, 5, and 10 years. DNA concentration, quantified by dot-blot hybridization, declined significantly for the first 2 years, but there was no significant further degradation from the second to the tenth year of storage. COfiler™ analysis was used and the allelic dropout ratio for the amelogenin locus relative to CSF1PO locus was also estimated. Statistically significant differences were found between fresh teeth and teeth from the 2- and 5-year groups but not from the 10-year group. Under our storage conditions most of the DNA degradation occurred during the first 2 years. Further research is needed to control for individual and external factors that could affect DNA.     

Criminal Exploitation of Online Systems by Organised Crime Groups

This article considers how information and communications technologies (ICT) can be used by organised crime groups to infringe legal and regulatory controls. Three categories of groups are identified: traditional organised criminal groups which make use of ICT to enhance their terrestrial criminal activities; organised cybercriminal groups which operate exclusively online; and organised groups of ideologically and politically motivated individuals who make use of ICT to facilitate their criminal conduct. The activities of each group are then assessed in relation to five areas of risk: the use of online payment systems, online auctions, online gaming, social networking sites and blogs. It is concluded that the distinction between traditional organised crime groups and the other two groups—cybercriminal groups and ideologically/politically motivated cyber groups—is converging, with financially-motivated attacks becoming more targeted. Legislation will need to adapt to deal with new technological developments and threats that organised criminals seek to exploit.

A fatal dichlorvos poisoning: concentrations in biological specimens

Abstract:  A 54-year-old man was found dead with a bottle containing a brownish fluid near him. A toxicological screening was carried out in blood, urine, and stomach content. Only dichlorvos (2,2 dichlorovinyl O-O dimethylphosphate or DDVP) was found. A simple and rapid method, using DDVP-D₆ as an internal standard, was developed for the determination of DDVP by gas chromatography/mass spectrometry (GC/MS). The method was linear from 1 to 10 mg/L. Intraday and interday precisions were all <15%. DDVP concentration in cardiac blood was approximately four times higher than in peripheral blood. A high concentration was found in the heart showing a cardiac tropism of DDVP, kidney and lung concentrations being much lower. No DDVP was found in liver. DDVP stomach content was 38 g. The amount presumed ingested was 82 g, c . 1000 mg/kg of body. The oral LD₅₀ for DDVP ranges between 20 and 1090 mg/kg in animals but is not known for humans.     

HAIRVEQ 2006: evolution of laboratories' performance after different educational actions

HAIRVEQ is a proficiency testing program for hair analysis of illicit drugs organized by the Istituto Superiore di Sanità (Rome, Italy) and the Institut Municipal d'Investigació Mèdica (Barcelona, Spain). The aim of the three exercises performed in 2006 was the evaluation of 32 laboratories' performance when analyzing the same hair sample containing opiates, cocaine and methadone, after carrying out some specific educational interventions. In the first round, the sample was sent to be analyzed following laboratory routine methodology. In the second round, standard operating procedures (SOP) for hair testing including sample preparation, method validation and qualitative and quantitative data evaluation, and an open hair sample for SOP training were also sent together with other hair samples including the one used for performance evaluation. After the second round, a workshop was held with participant laboratories to discuss methodological issues and interpretation of obtained results. An additional amount of open samples was distributed to the laboratories for implementing the SOPs. In the third round, the same unknown sample containing opiates, cocaine and methadone was resent for the final evaluation of laboratory performance. In the first round, 11 incorrect qualitative results (10 false negative and 1 false positive) were reported by seven laboratories (22%), in the second round, a reduction in the number of incorrect results was observed (4 false negatives and 1 false positive were reported by four laboratories, 13%) and in the third round, 5 false positives and 5 false negatives were reported by seven laboratories (22%). Concerning quantitative results, the scatter was similar between the three rounds and similar to the ones reported by other proficiency tests in hair analysis. More educational actions should be addressed to a group of laboratories, which did not yet show satisfying qualitative and quantitative results.     

The PCL: YV and recidivism in male and female juveniles: a follow-up into young adulthood

Adolescents, and most recently, adolescent females, have emerged as an important population in violence risk assessment and have sparked a debate regarding the downward and gendered extension of the Psychopathy Checklist: Youth Version (PCL:YV). This article evaluates the differential prediction of the three and four-factor models of the PCL:YV for male (n=201) and female (n=55) juvenile offenders using a prospective four and one-half year follow-up (M=3 years) study. Both models of the PCL:YV were significant predictors for boys; however, contrary to findings from studies using shorter follow-up periods, the predictive power was due primarily to the behavioral features of psychopathy. The PCL:YV was not a significant predictor of non-violent or violent recidivism for girls. This study does not lend support for the use of the PCL:YV as a risk factor for girl offenders. More research is needed to understand the application of the psychopathy construct in youth, particularly in girls.     

Characterization of lesions in hanging deaths

Hanging is a common method of committing suicide and a routine task in medico-legal autopsies. The hanging mark is the most relevant external sign and its characteristics are well known, but, for unknown reasons, there are major differences in reports on internal findings. We retrospectively studied 228 consecutive cases of hanging deaths. A complete standard autopsy was performed for every case. We investigated the association between the characteristics of the hanging mark and the frequency of bone, cartilage, soft tissue, and vascular injuries with the mode of suspension. Most cases (75.3%) presented some kind of bone or cartilage fracture, but these were unrelated to any of the variables studied. Vascular lesions are clearly more infrequent: intimal injuries were found in the carotid artery (9.1%), the jugular vein (2.2%), and ruptures of the carotid adventitial layer (21.7%). These could be partially associated with the use of a hard fixed noose and body weight.
