Carbon and nitrogen stable isotopes as indicative of geographical origin of marijuana samples seized in the city of São Paulo (Brazil)

The drug trafficking is one of the most serious problems related to the Public Safety in Brazil, especially in the most populous areas of the country, as is the case of the city of São Paulo. In this work, it was developed a methodology that can help tracking the traffic routes of marijuana samples seized in the city of São Paulo, based on stable carbon and nitrogen isotopes, which are related to the climate and plant growth conditions. A model to classify the origin of unknown samples was built using linear discriminant analysis based on about 150 samples apprehended in the main producing regions of the country. Results for 76 samples seized in the city of São Paulo showed that most of them were cultivated in a humid region with the same origin as those from Mato Grosso do Sul. The provenance of 13 outliers samples from Northeast region (an important producing region) also were evaluated and some of them presented same profile of those from Mato Grosso do Sul, pointing to the existence of the traffic routes between the Northeast and Midwest region, probably as a consequence of the intensive field raids by Brazilian Federal Government since 1999.     

Differences in the Validity of Self-Reported Drug Use Across Five Factors: Gender,Race, Age,Type of Drug,and Offense Seriousness

This study expands our knowledge about the validity of self-reported drug use by examining how gender, race, age, type of drug, and offense seriousness interact to affect the validity of self-reported drug use. This study also provides a conceptual framework that can be used to examine the validity of self-reported drug use. Differences in the validity of self-reported drug use are explained by examining differences in underreporting and overreporting. Differences in underreporting and overreporting are then further examined while controlling for differences in base rates of drug use. As shown, whether one controls for base rates of use may drastically affect estimates of underreporting and overreporting. By using hierarchical loglinear, logit, and logistic regression models with the Drug Use Forecasting data, we show that Black offenders provide less accurate self-reports than White offenders. Black offenders do so because they are more likely to underreport crack/cocaine use than White offenders. This difference, however, disappears once differences in base rates are controlled. A Black offender who tests positive is not more likely to underreport crack/cocaine use than a White offender who tests positive. Black offenders are also more likely to overreport both marijuana and crack/cocaine use relative to White offenders. Contrary to the first, this difference is not attributable to a difference in base rates. Methodological and substantive implications of this distinction are discussed. No differences across gender, age, or offense seriousness were found.

Judicial Murder‐Suicides in Van Diemen's Land

On the morning of December 17, 1827, nine convicts were executed by public hanging in Hobart Town, the capital of the British colony of Van Diemen's Land (now the Australian state of Tasmania). Two months previously they had drowned senior Constable George Rex on Small Island, which was part of the penal settlement at Macquarie Harbor, in front of five bound and gagged witnesses. They offered no defence at their trial. Examination of the Tasmanian colonial convict records shows that “suicide by lottery” involved convicts choosing two men, one to die and the other to kill him. The witnesses would earn a respite when taken away for the trial, and the murderer would be executed. “Death by gallows” could be considered a nineteenth‐century version of an orchestrated suicide reminiscent of more modern “death by cop.” This category of “judicial” murder‐suicide expands the range of contemporary classifications of dyadic deaths.     

An Analysis of The Morbidity and Mortality of Diabetes Mellitus in a Forensic Context

To investigate the spectrum of diseases seen in diabetes mellitus in a forensic context, all autopsy reports of diabetic individuals who presented to Forensic Science, South Australia (FSSA), over a 5‐year period from 2005 to 2009 were studied. The leading cause of death was cardiovascular disease (55.0%), followed by unnatural deaths (15.4%) and infections (9.4%). In type 1 diabetics, principal causes of death included cardiovascular disease (44.7%), acute metabolic complications (18.7%), unnatural deaths (17.9%), and infections (8.9%). However, frequencies of these diseases differed in type 2 diabetics, with cardiovascular events responsible for 56.6% of cases, followed by unnatural deaths (15.0%) and infections (10.9%). A larger number of male deaths were seen in all disease categories, except respiratory and gastrointestinal where the frequencies were similar to females. Cardiovascular disease was the leading overall cause of death across all ages except in those under the age of 30 where metabolic complications were more common.     

Illicit payments for illicit goods: noncontact drug distribution on Russian online drug marketplaces

The distribution or consumption of traditional drugs has become the subject of stringent penalties throughout most of the world and synthetic designer drugs have become the alternative. Novel psychoactive substances, also called ‘legal highs’, are highly varied in terms of chemical composition. These substances are advertised and distributed as an alternative to traditional drugs on the Internet, making identification of new substances and enforcement difficult. For this article, we downloaded and analysed 28 Russian-language online drug marketplaces which distribute traditional and novel psychoactive substances. All marketplaces used a noncontact drug dealing method where the seller and the buyer communicate through the Internet to arrange for payment and delivery of drugs without meeting face-to-face. Geographic information, price, amount, substance type and payment method data were extracted. Findings indicate such marketplaces are able to operate due to the ability of their clients to pay anonymously with the virtual currencies – Qiwi and Bitcoin.     

Foreigners Dying in Istanbul

Abstract:  The study included 411 deaths selected from 14,647 medicolegal deaths autopsied in the Morgue Department of Forensic Medicine Institute Directorate, affiliated with the Ministry of Justice, between 1998 and 2002. Data were collected from court documents, coroner's investigation reports, and autopsy reports. The parameters of age, gender, nationality and origin, cause and place of death in foreigners dying in Istanbul were evaluated in the study. Out of 14,647 medicolegal deaths, 3.5% were foreigners from 34 different nationalities. The nationality with the highest rate of foreigner deaths (34%) was Romanian. Out of 411 deaths, 74.3% were male and 25.7% were female. Of all cases, 64.4% were tourists visiting Istanbul and 35.6% had a job in Istanbul. Of 146 foreigners employed in Istanbul, 94.5% did not have a work permit, while only 5.5% had a work permit.     

Excessive Uniformity in Federal Drug Sentencing

The ideal of fair and proportionate punishment was a major impetus for federal sentencing reform. Observers of the current federal drug sentencing regime contend that the sentencing guidelines and mandatory minimums lead to the problem of “excessive uniformity” in which offenders of widely differing culpability receive similar sentences due to the dominance of drug quantity as a sentencing factor. This study investigates this phenomenon using the 1997 Survey of Inmates in Federal Correctional Facilities. Controlling for relevant offense, offender, and case processing variables, the analysis finds that the quantity-driven sentencing fails to account for important differences in offender culpability—resulting in excessively uniform sentences for offenders with highly dissimilar roles in the offense. The main policy implication of this research is that the central, organizing role of drug quantity in federal drug sentencing needs to be rethought. Indeed, effectively dealing with the problem of excessive uniformity will likely require the wholesale restructuring of how federal sentences for drug offenders are determined.
