Operational parameters in the stolen property system

The operational steps involved in the theft of property are identified and discussed with central attention being given to the criminal receiver of stolen goods—the “fence”. Both the likely and unlikely divisions of labor in the stolen property marketplace are analyzed as are the functional progressions of events in the theft industry. The analysis is based on a field research project.     

One Way or Another? Criminal Investigators’ Beliefs Regarding the Disclosure of Evidence in Interviews with Suspects in England and Wales

The research base concerning interviews with suspects remains to be comprehensively developed. For example, the extant literature provides differing views regarding how best to undertake the important interview task of disclosing evidence. In the current study, using a self-report questionnaire, 224 investigators based in England and Wales were asked as to their own preferred methods. Most respondents advocated a gradual method of disclosing evidence, stating that this approach would better reveal inconsistencies and obtain a complete version of events (similar to the reasoning of those who preferred disclosing evidence later). Those who advocated revealing evidence early stated this approach would more likely elicit confessions. Several respondents would not commit to one single method, arguing that their chosen strategy was contextually dependent. The study’s findings suggest that it remains arguable as to whether there is one best approach to evidence disclosure and/or whether particular circumstances should influence interviewing strategies.     

Comparison of the variables affecting the recovery of DNA from common drinking containers

As the boundaries of forensic DNA profiling continue to expand, less obvious sources of biological evidence are being collected at crime scenes for DNA profiling. One example is the recovery of biological evidence from common drink containers, such as bottles and cans, which have been found at crime scenes. There are many variables that may have an impact on recovering a DNA profile from such exhibits. In this research, the effects of person to person variation, time, type of drink (including alcoholic and non-alcoholic beverages), and type of drink container, were assessed for their impact on the major analytical outcomes of the DNA process. The results show that the alpha-amylase activity varies from individual to individual and is reduced in the presence of some alcoholic drinks. A reasonable DNA yield was obtained from all samples, however, the concentrations exhibited significant person to person variation. The type of drink container influenced the DNA yield with cans giving a higher yield than bottles of the same drink type. To a reduced extent the presence or absence of alcohol affected the overall DNA yield and when partial or failed DNA profiles were produced they were more likely to be associated with alcoholic drinks than non-alcoholic drinks.     

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.     

Sequence variation in humans and other primates at six short tandem repeat loci used in forensic identity testing

A large number of alleles from the six different short tandem repeat (STR) loci FGA, D3S1358, vWA, CSF1PO, TPOX and TH01, used in human identity testing were sequenced to provide support for the robustness of fluorescent STR DNA typing by allele size. Sequence information for some of these loci (FGA, vWA, TH01) is an extension of published work, whereas no extensive sequence information is available with respect to the D3S1358, CSF1PO, and TPOX loci. Sequencing of alleles at each locus has provided quantitative data with respect to the true nucleotide length of common alleles, and of alleles that vary in length from the common alleles. All alleles that were identified as "off-ladder" alleles through fluorescent typing at these STR loci have proven to be true length variant alleles. Sequencing at the D3S1358 and CSF1PO loci allowed for the establishment of a common nomenclature for these loci. A correlation between percent stutter and the length of the core tandem repeat is demonstrated at the FGA locus. Alleles in which the core tandem repeat is interrupted by a repeat unit of different sequence have a reduced percent stutter. DNA samples from three non-human primates (chimpanzee, orangutan, and gorilla) were compared to the human sequences, and shown to differ markedly across loci with respect to their homology. The effects of primer binding site mutations on the amplification efficiency at a particular locus, and methods used to interpret amplification imbalance of heterozygous alleles at a locus is also addressed.

Industrial relations and manpower

This article provides the first empirical evidence on the impact of Best Value processes on local service quality, costs, efficiency and accountability. Views were obtained from a wide range of personnel involved in the pilot programme in Wales by means of a postal questionnaire and interviews. The evidence shows that so far Best Value has had a positive impact on quality and accountability but little impact on service costs. Perceptions of the impact of Best Value are significantly more positive in authorities that adopted a corporate approach to the pilot process.
