Abstract Background DNA profiling has proven to be a valuable technique for identification of individuals in crime. Currently, the technique targets several short tandem repeat (STR) regions in human genome. However, increasing number of samples submitted for STR analysis may lead to delays due to the limited number of experienced analysts who might be available at any given moment and the time taken to complete lengthy DNA profiling procedures. This study was conducted to test the specificity, repeatability, reproducibility and robustness of Investigator® 24plex GO! kit for genotyping of reference samples submitted to the Royal Malaysian Police Forensic DNA Laboratory for DNA database. Material and methods In this study, Investigator® 24plex GO! kit was used to directly amplify STR loci from buccal swab cell of reference samples that had previously been STR typed using GlobalFiler™ Express kit. Capillary electrophoresis was carried out on a 3500xL Genetic Analyser using POP-4® Polymer. Amplified products were assigned to particular STR alleles using the GeneMapper ID-X version 1.4 software. Results Our study shows that STR profiles generated using Investigator® 24plex GO! gave concordance results with those previously obtained using the GlobalFiler™ Express kit. In addition, quality sensors included in the kit are of particular importance for determining the effectiveness of the PCR reaction and help to indicate the nature and quantity of DNA template for PCR amplification. Conclusion The Investigator® 24plex GO! kit is reliable for STR typing of reference samples.

Little is known about the social correlates of serial rape or about trends in offending across time and space in the United States. Furthermore, the limited serial rape scholarship that exists was largely generalized from small, captive samples. The current study aims to amplify our understanding of serial rape by pursuing three fundamental objectives. First, guided by theory and research we propose a new, more precise, and comprehensive conceptualization of serial rape. Next, we draw from media representations of serial rape published in five major American newspapers from 1940 to 2010 to develop an offender social profile and to identify patterns in attack style. Our analysis of a broad and diverse sample of serial offenders described in media accounts ( N = 1,037) produced the following profile estimates—age: 27 years; race/ethnicity: African American, 46%; Caucasian, 29%; Latino, 19%; Asian, 5%. Most offenders were employed in unskilled or semiskilled occupations and the most common attack strategy was the surprise approach (47%). Finally, our data allow us to estimate and interpret historical trends as depicted in media accounts. Our analysis revealed low levels of serial rape in newspaper accounts during the 1940s to 1950s, followed by a steady increase (with periodic decreases) leading to a peak in 1991. This peak is followed by a steady and dramatic decline from 1992 to 2010.

This article explores the place of ‘ethnicity’ in the operation, management and contestation of the UK National DNA Database (NDNAD). In doing so, it examines the limitations of bioethics as a response to political questions raised by the new genetics. The UK police forensic database has been racialised in a number of distinct ways: in the over-representation of black people in the database population; in the classification of all DNA profiles according to ‘ethnic appearance’; in the use of data for experiments to determine the ethnicity of crime scene DNA; and in the focus on ethnicity in public debate about the database. This racialisation presented potential problems of legitimacy for the NDNAD but, as the article shows, these have been partly neutralised through systems of ethico-political governance. In these systems of governance discussion of institutional racism has been postponed or displaced by other ways of talking about ethnicity and identity.
