GC-MS and GC-IRD analysis of 2-, 3- and 4-methylmethamphetamine and 2-, 3- and 4-methylamphetamine

4-Methylmethamphetamine has been detected in samples submitted for analysis in several states throughout Australia. Six ring substituted methyl isomers of methamphetamine and amphetamine were synthesised and analysed. As the regioisomeric 2-, 3- and 4-methylmethamphetamine and 2-, 3- and 4-methylamphetamine have virtually identical mass spectra, the use of MS is an ineffective technique to discriminate between these closely related compounds. We set out to determine whether the regioisomers could be differentiated by a combination of GC-MS, acetyl derivatisation and GC-IRD. We demonstrate that the three isomers of methylmethamphetamine and methylamphetamine can be separated by GC, and a combination of acetyl derivatisation and vapour phase IR can identify the specific ring substituted compound.     

Physical and mechanical degradation of shirting fabrics in burial conditions

The current focal areas within forensic textile science are fibre identification and assessment of the method of damage to fabrics. This paper investigates fabric degradation within clandestine burials. The fabrics considered in this paper, unlike previous archaeological studies, are a modern polyester-cotton blend (65%/35%) and a 100% cotton fabric both of which are commonly used for men's shirting fabrics in the UK. Three laundering conditions were investigated (i) not-laundered, (ii) laundered 6 times, and (iii) laundered 60 times; this represented varying conditions of fabric upon clothing deposition. The two burial conditions; sand and clay, were selected as extremes of soil type. The deposition times (15 and 30 days) were based on a study of clandestine burials in UK crimes. There were clear differences in how polyester-cotton and cotton stained within the two different soil conditions, polyester-cotton becoming extensively stained after a 30-day deposition in sand. The tear force required to tear the fabric after deposition, suggested that polyester/cotton fabrics were consistently weaker after burial, regardless of soil type and deposition period. There was also significant damage caused to not-laundered cotton fabrics after a 30-day deposition in clay. This work indicates that common apparel fabrics can degrade in relatively short times when buried.     

Learning in practice for becoming a professional forensic expert

The study explores the professional development of future forensic experts. Specifically, it investigates how the forensic expert trainees learn through the internal training program at the Swedish National Laboratory of Forensic Science with a focus on the supervision at work. The findings are drawn from an ethnographical study where five trainees and their supervisors have been observed and interviewed. By drawing on a socio cultural perspective on learning, the results show that supervision is crucial for professional development. Two types of activities and relations define how supervision is implemented. There is a "transitional movement" in how supervision is staged depending on the trainees' gradual changes in participation in the work practice and increased experience. Forensic experts need skills and know-how to make wise and impartial judgments, i.e. a kind of tacit professional practical knowledge, as well as the skill to communicate with other professionals. However, the development of a professional language is somewhat unspoken or planned. Becoming a forensic expert is a learning process in practice where supervision plays a decisive role in maintaining the professional knowledge in the judicial system. Therefore, supervision for supervising might be a valuable support for supervisors.     

Predicting discharge in forensic psychiatry: the legal and psychosocial factors associated with long and short stays in forensic psychiatric hospitals

In Germany, both the number of patients treated in forensic psychiatric hospitals and the average inpatient treatment period have been increasing for over thirty years. Biographical and clinical factors, e.g., the number of prior offences, type of offence, and psychiatric diagnosis, count among the factors that influence the treatment duration and the likelihood of discharge. The aims of the current study were threefold: (1) to provide an estimate of the German forensic psychiatric patient population with a low likelihood of discharge, (2) to replicate a set of personal variables that predict a relatively high, as opposed to a low, likelihood of discharge from forensic psychiatric hospitals, and (3) to describe a group of other factors that are likely to add to the existing body of knowledge. Based on a sample of 899 patients, we applied a battery of primarily biographical and other personal variables to two subgroups of patients. The first subgroup of patients had been treated in a forensic psychiatric hospital according to section 63 of the German legal code for at least ten years (long-stay patients, n=137), whereas the second subgroup had been released after a maximum treatment period of four years (short-stay patients, n=67). The resulting logistic regression model had a high goodness of fit, with more than 85% of the patients correctly classified into the groups. In accordance with earlier studies, we found a series of personal variables, including age at first admission and type of offence, to be predictive of a short or long-stay. Other findings, such as the high number of immigrants among the short-stay patients and the significance of a patient's work time before admission to a forensic psychiatric hospital, are more clearly represented than has been observed in previous research.     

Recent Iowa trends in sudden unexpected infant deaths: the importance of public health collaboration with medical examiners' offices

During the winter in 2008, Iowa experienced an increase in sudden unexplained infant deaths (SUIDs). SUIDs and infectious causes of infant deaths generally average 3 monthly (SD = 1.0) in Iowa. However, in January 2008, 9 infant deaths were reported to the Iowa Department of Public Health and the Iowa Office of the State Medical Examiner. Between January and March of 2008, joint investigation of 22 SUIDs was conducted. The investigations required the involvement of multiple medical examiners from various jurisdictions, testing for pathogens at the University Hygienic Laboratory, epidemiologic support from the Iowa Department of Public Health, and consultation with the Centers for Disease Control and Prevention. The preliminary hypotheses for the increase in the infant mortality included viral respiratory disease and/or possible novel respiratory viral infections being the cause. Collaboration between public health and the medical examiner offices resulted in timely assessment of the cases. While no single causative agent was responsible for the increase seen in the number of infant deaths, respiratory pathogens played a role in the deaths of 15 of 22 children.     

Criminology and victimology of rape in context with war-like conflicts using the example of the former Yugoslavia and Rwanda

The topic of this article is sexual violence in context with war-like conflicts in the former Yugoslavia and Rwanda. The fundamental categories of sexual violence in war-like conflicts are described. The authors discuss the types of sexual violence as defined in the report of the UN Commission of Experts on the war-like conflicts in the former Yugoslavia. Four criminal trials were evaluated: three held before the International Criminal Tribunal for the Former Yugoslavia (ICTY) in The Hague/Netherlands and one before the International Criminal Tribunal for Rwanda (ICTR) in Arusha/Tansania. The defendants were found guilty of torture, crime against humanity and genocide. Potential procedures with respect to similar crimes in current or prospective conflicts are discussed. An alternative may be the assignment of medical personnel (for example of the German Federal Armed Forces). Finally, the post-war cooperation between the Institute of Legal Medicine at the University Medical Centre of Hamburg-Eppendorf as well as the medical and government institutions in Rwanda is presented, which has been going on since 2005.     

Fixation of cells for analysis by laser microdissection--comparative studies in forensic trace material

This paper is focused on the preparation of samples for laser microdissection (LM) in forensic casework. In forensic genetics, it is essential to preserve and separate cellular traces during sample preparation, as they are usually gathered in very small amounts and are often contaminated with undesired cells. This is made possible by laser microdissection, a technique developed to cut cells or tissue of a certain type from a microscopical specimen by UV laser and catapult them directly into a PCR reactor. This method minimizes the risk of getting inconclusive, mixed DNA profiles due to contamination by foreign DNA and also supplies information about the cellular origin of a DNA profile. A method for optimized fixation and staining of spermatozoa for laser microdissection was established. Four different fixation methods combined with two staining methods were tested on two different microscope slides. Moreover, the effect of a blocker pen to contain the specimen on the slide was investigated.     

The role of empathy in anger arousal in violent offenders and university students

A lack of empathic responsiveness toward others has been consistently identified as an important antecedent to aggressive behavior and violent crime, with many rehabilitation programs for violent offenders incorporating treatment modules that are specifically designed to increase offender empathy. This study examined the extent to which cognitive (perspective taking) and affective (empathic concern, personal distress) empathy predicted anger in a clinical (male prisoners convicted of a violent offense) and a nonclinical (student) sample. Perspective taking emerged as the strongest predictor of self-reported anger in response to an interpersonal provocation, as well as being most consistently related to scores on measures of general trait anger and methods of anger control. While the relationship between perspective taking and anger was apparent for offenders as well as students, the results did not support the idea that an inability to perspective take is a particular characteristic of violent offenders.     

Still hazy after all these years: the law regulating surrogacy

In 1997, Margaret Brazier was asked by the then Government to chair a review of the laws regulating surrogacy. The subsequent Brazier Report made a number of recommendations, including the need for greater regulation and the tightening of 'expenses' payments. Fifteen years on, the limitations in the legal regulation of surrogacy have become increasingly clear. Yet, none of Brazier's recommendations have been adopted, despite the clear opportunity for revisiting the regulation of surrogacy offered during the passage of the Human Fertilisation and Embryology Act (2008). In this paper, we revisit the Brazier Report in the light of subsequent developments and assess to what extent its key findings remain salient. Brazier's recommendations will thus provide a jumping off point for a critical analysis of the current state of the law regarding surrogacy.
