Cryptic chemical identification as a crime intelligence aid.

A dead body was found near the sea and a commercial port in north-east Italy. The man had been shot and then burnt, by using a large volume of fire accelerant. The chemical composition of the flammable mixture had to be determined in order to aid police investigations. GC-MS analysis of residual cloth and soil identified a common gasoline, together with some unrelated compounds deriving from the container used to carry the inflammable liquid. A reconstruction of the event, an examination of the surroundings where the crime took place and the cryptic chemicals found, enabled the investigators to restrict and intensify their enquiries within a specific area.     

Multi-sector cooperation in preventing crime: the case of a South African Neighbourhood Watch as an effective crime prevention model

Abstract

This case study describes the experience of effective and sustainable multi-sector co-operation in the prevention of crime between the Roodekrans Neighbourhood Watch (RNW) in Roodepoort, South Africa, the South African Police Service, private security businesses and the local business sector. This case study is illustrated in the context of empowering communities to take ownership of community safety by facilitating a multi-sector approach. Many studies have highlighted the role of the police in driving crime prevention, however, this paper focuses on the role and contribution of communities themselves as an effective vehicle of crime prevention drawing on multi-sector co-operation. Knowledge regarding best practices in this field of crime prevention remains a work in progress, therefore this paper aims to contribute to the general framework for the growth of successful multi-sector community-based crime prevention initiatives.

Age as a basis for allocating lifesaving medical resources: an ethical analysis

In light of the growing prominence of an age criterion in patient selection, it is essential to scrutinize the ethical legitimacy of arguments being offered both for and against using age as a criterion. Accordingly, the present study first explores the primary justifications for an age criterion, then examines the criterion's weaknesses. Weaknesses are grouped into two areas: deficiencies in the justifications of the criterion, and overarching critiques. Finally, a way forward in the midst of the present controversy is suggested. The study's conclusion is that an age criterion per se is unjustified, though age may play a carefully defined role in medical assessments relevant to patient selection.     

STR melting curve analysis as a genetic screening tool for crime scene samples

In this proof-of-concept study, high-resolution melt curve (HRMC) analysis was investigated as a postquantification screening tool to discriminate human CSF1PO and THO1 genotypes amplified with mini-STR primers in the presence of SYBR Green or LCGreen Plus dyes. A total of 12 CSF1PO and 11 HUMTHO1 genotypes were analyzed on the LightScanner HR96 and LS-32 systems and were correctly differentiated based upon their respective melt profiles. Short STR amplicon melt curves were affected by repeat number, and single-source and mixed DNA samples were additionally differentiated by the formation of heteroduplexes. Melting curves were shown to be unique and reproducible from DNA quantities ranging from 20 to 0.4 ng and distinguished identical from nonidentical genotypes from DNA derived from different biological fluids and compromised samples. Thus, a method is described which can assess both the quantity and the possible probative value of samples without full genotyping.     

Secondary victimization and the collective identity of crime victims: a qualitative analysis of Swedish crime news discourse

This article presents an analysis of how secondary victims of murder—in this context, the parents or close family members of a primary murder victim—are represented in Swedish crime news discourse. The study is based on a discourse analysis of media coverage of secondary victims, and statements made by them, in relation to four highly publicized murder cases during the last two decades. The analysis shows that portrayals of secondary victimization reinforce the conflictual character of victim–offender relationships in the news, but also limit the conditions for talking about the significance of social support, mediation and reconciliation for crime victims. News representations of crime victims become less clearly marked by the characteristics of the ‘ideal’ victim as secondary victims, and persons who are explicitly critical toward the legal system, claim victimhood. Furthermore, the identity of the crime victims’ movement as a collective becomes destabilized when the category of the victim is widened to include individuals whose interests are framed as subjective, rather than related to the needs of other crime victims or the general public. In sum, increased media focus on secondary victims may thus undermine the legitimacy of victim claims in public discourse.     

Hyperpigmentation in the long bones of the lower limbs as a basis for vehicle identification and traffic accident reconstruction

Following the earlier studies on the identification of injuries in unbroken cranial bones, the described method was adapted for the examination of the long bones in fatal casualties of traffic accidents.Two types of bumper injuries might occur: the bumper was found to cause fracturing of limbs [1], and femoral muscle contusions and microtraumas within compact and spongiose parts in the femoral with subsequent maculate hyperpigmentation [2].The authors show that the correlation of above mentioned traces of the trauma, facilitates the reconstruction of the accident and also the identification of the vehicle.     

Immigration and crime: a time-trend analysis of self-reported crime in Sweden, 1999–2017

ABSTRACT

This study investigates the direction and rate of change in self-reported crime over time, based on immigrant status and region of origin. The study is based on eight nationally representive school surveys conducted by the National Council for Crime Prevention between 1999 and 2017, with a sample of 50,657 adolescents. Results in this study showed a decreasing trend in self-reported offending among both first and second generation immigrant youth, and also among immigrant youths from different regions of origin. The results also show that offending has declined at a faster rate among first generation immigrants by comparison with native Swedes.     

Mental disorder as the cause of a crime

An offender's punishment can be reduced when a court decides that his mental disorder reduces his responsibility for what he did. Courts have sought to establish whether a mentally disordered offender's responsibility is reduced by asking whether his disorder caused the crime. Acceptance of this “causation by mental disorder” criterion has fluctuated, however. This may be because causal explanations are not the types of explanations we are accustomed to offering for the kinds of acts that bring defendants, and psychiatric witnesses, to court. More often, we offer what philosophers have called “possibility” explanations for these acts. The application of psychiatry to possibility explanations has not been widely explored. It offers the potential for the improved use of psychiatric evidence in criminal proceedings.     

Violence as unresponsiveness: Toward a new conception of crime

A theory of crime and violence as “unresponsiveness” was inferred by translating concepts of American criminology into Norwegian. According to this theory, punishment of offenders is a product of a criminality that the punishers share. Reducing crime and violence entails decentralizing and democratizing government. The practice of criminology—testing propositions about crime and violence—becomes problematic.     

The maharishi effect: A model for social improvement. Time series analysis of a phase transition to reduced crime in merseyside metropolitan area

Abstract

Time series analysis was used to test the hypothesis that Merseyside crime rate was reduced by a group practising Maharishi Mahesh Yogi's Transcendental Meditation and TM-Sidhi programme. Previous research suggests that a phase transition to increased orderliness u evidenced by reduced crime rate should occur when the group size approaches the square root of 1% of the total population. Analysis of Merseyside monthly crime data and coherence group size from 1978 to 1991 shows that a phase transition occurred during March 1988 with a 13.4% drop in crime when the group size first exceeded the √1 % or Maharishi Effect threshold (p < 0.00006). Up to 1992, Merseyside crime rate has remained steady in contrast to the national crime rate which has increased by 45%. In 1987 Merseyside had the third highest rime rate of the eleven largest Metropolitan Areas in England and Wales; by 1992 it had the lowest crime rate. 40% below levels predicted by the previous behaviour of the series. There were 255,000 less crimes in Merseyside from 1988 to 1992 than would have been expected had Merseyside continued to follow the national crime trend. Home Office figures indicate savings to Merseyside could exceed £1250 million for the five year period. Demographic changes, economic variables, police practice, and other factors could not account for the changes.     

Identifying the scene of a crime through pollen analysis

The forensic analysis of pollen involves the comparison of crime scene and reference pollen samples. Successful matches are frequently used to solve time- or location-related crimes. Despite its prospects in criminal investigation, forensic palynology is still underused in casework due to inherent shortcomings such as its limited evidential weighting, scarcity of skilled palynologists dedicated to forensic casework and the laborious nature of analytical procedures. To address these challenges, the current state-of-the-art in forensic palynology is transiting from the traditional light microscopic methods that dominated the early days of palynology to more contemporary approaches like Raman spectroscopy, stable isotope analysis and DNA metabarcoding. The major challenges of these methods, however, include a lack of optimisation to forensic expectations and the unavailability of robust databases to permit accurate data interpretation, and quests to resolve these problems constitute the theme of current research. While reiterating the usefulness of pollen analysis in criminal investigation, this report recommends orthogonal testing as a way of improving the evidential weighting of forensic palynology.

Juror decision making for juveniles tried as adults: the effects of defendant age,crime type,and crime outcome

This study examined the influences of the crime type (person or property) and the crime outcome (mild or severe) on mock jurors’ verdict and sentencing decisions for adult defendants and juvenile defendants tried as adults. Jurors read a trial summary depicting a defendant charged with aggravated robbery or second-degree burglary. The crimes had either mild or severe damage inflicted on the person or property, and the defendant's age was presented as 14 or 24. Neither the defendant age nor the crime outcome affected jurors’ verdicts; however, jurors were more likely to convict a defendant charged with a crime against a person. Jurors recommended longer sentences for an adult defendant, a defendant charged with a crime against a person, and a defendant charged with a crime with a severe outcome. The discussion explored these outcomes and the role of bias in jurors’ perceptions of defendants.     

The New Zealand DNA databank: its development and significance as a crime solving tool.

The New Zealand DNA Databank was established following the introduction of legislation in August 1996. Using the Second Generation Multiplex (SGM), DNA profiles from over 13,000 convicted offenders and volunteer donors have been completed to the National DNA Database. Since June 1998, DNA profiles from over 1,400 unsolved crimes have been entered onto the Crime Sample Database. Of all unsolved crimes analysed, 33% are linked to individuals and 21% are linked to other unsolved crimes. Several high profile types of case including homicides, sexual offenses and burglaries are amongst those regularly solved.
