Validation of the InnoXtract™ DNA extraction method for bone,teeth, and rootless hair

Forensic casework samples often include human hairs, teeth, and bones. Hairs with roots are routinely processed for DNA analysis, while rootless hairs are either not tested or processed using mitochondrial DNA. Bones and teeth are submitted for human remains identifications for missing persons and mass disaster cases. DNA extraction from these low templates and degraded samples is challenging. The new InnoXtract DNA extraction method utilizes magnetic beads that are optimized to bind small DNA fragments, as small as 100 base pairs, to purify high-yield DNA from compromised samples. This validation study evaluates InnoXtract's ability to obtain amplifiable DNA from samples such as rootless hairs and skeletal remains. Studies performed include sensitivity, stability, repeatability, reproducibility, non-probative samples, and comparison to standard organic extractions. Sensitivity studies demonstrate average yield recoveries ranging from 53% to 100% and 73% to 85% for the InnoXtract hair and bone methods, respectively. Studies demonstrate consistent results across a range of sample types, such as insulted and un-insulted bone and teeth, as well as hair shafts from donors of various ages, gender, race, and hair characteristics. The InnoXtract bone method outperformed organic extraction. The method was successfully automated on a MagMAX™ Express-96, with recoveries over 70% relative to the manual version. InnoXtract has the potential as an automated high-throughput, high-yield bone extraction method with 6 h of total extraction time for up to 96 samples. The validation study results demonstrate that the InnoXtract kits produce high-yield and high-quality DNA from compromised bone, teeth, and hair shaft samples.     

Characteristics of female patients admitted to an adolescent secure forensic psychiatric hospital

Bluebird House is the only mixed gender NHS secure forensic psychiatric hospital for adolescents in the South of England. It has admitted more than 30 female patients since the service opened in 2008. The admission criteria are that patients must be detained under the Mental Health Act and present evidence of being a risk of harm to others. This article describes the clinical characteristics of 30 consecutive female patients admitted to a highly specialised adolescent forensic inpatient service. Key results include a very high rate of incidents of risk behaviours exhibited by female patients within the unit but good clinical outcomes. The majority of patients had severe symptoms of mental disorder, especially emotional instability, self-harm behaviours and aggressive behaviours. Few had diagnoses of mental illness. Assessment findings from the Millon Adolescent Clinical Inventory and the Structured Assessment of Violence Risk are discussed, as are parallel with studies from other female secure services.     

Use of Craniofacial Superimposition in Historic Investigation

A skeleton discovered in Grand Forks, North Dakota was purported to belong to Clelland “Clell” Miller, a James‐Younger gang member, who was killed during the Northfield Bank robbery on September 7, 1876. A 3‐D image from a computer tomography (CT) scan of the skull was obtained, and a craniofacial superimposition was conducted to determine if the skull could belong to Miller. The superimposition method used in this case was to overlay the CT image of the skull onto Miller's postmortem photograph. In addition to the craniofacial superimposition, the images were juxtaposed to compare similarities or differences in facial morphology between the skull and photograph. Superimposition methods can be used to exclude identifications; however, they should not be used as a conclusive method for identification. In this case, there were sufficient similarities between the skull and Miller's photograph; therefore, the skull could not be eliminated as possibly being that of Miller.     

False positive and false negative rates in self-reported intentions to offend: A replication and extension

Purpose

Studies of criminal decision making commonly rely on college students’ self-reported intentions to commit a hypothetical offense. The current study evaluates the predictive validity of these intentions to offend.

Methods

Undergraduate students (n = 726) read a fictitious but seemingly realistic newspaper article describing an illegal opportunity for acquiring digital music files, and then reported their intentions to act upon the opportunity. Afterward, participants’ real world attempts to follow-through on the opportunity were monitored covertly.

Results

Findings reveal that participants who reported weak intentions to offend typically refrained from the act, resulting in a low false negative rate. However, those who reported strong intentions to offend also typically refrained from the act, thereby resulting in a high false positive rate.

Conclusions

These findings suggest that while participants’ predictions of criminal abstention are generally accurate, their predictions of criminal involvement are more problematic. Such faulty intentions have important implications for research on criminal decision making.     

‘Managing’ the Middle Classes: Urban Managers,Public Services and the Response to Middle-Class Capture

There is a longstanding concern about middle-class capture of the benefits of public service provision, although relatively little evidence exists on the exact nature of any advantage or on the processes by which this comes about. Using a framework developed from Gal (J. Gal, 1998. Formulating the Matthew Principle: on the role of the middle-classes in the welfare state. Scandinavian Journal of Social Welfare, 7, 42–55), and via two case studies of street cleansing services in the UK, the article explores the ways in which middle-class service users assert influence in relation to service design, resource allocation and practice on the ground. It explores how urban managers respond to middle-class influence, revealing the ways in which influence is accommodated and the benefits of this to middle-class service users. It also evidences how urban managers attempt to resist aspects of middle-class advantage, and the challenges such resistance presents. The article concludes that the need to ‘manage’ middle-class influence permeates the routine institutional policies and practices of this key public service.     

Recovery of human DNA profiles from poached deer remains part 2: Improved recovery protocol without the need for LCN analysis

Although poaching is a common wildlife crime, the high and prohibitive cost of specialised animal testing means that many cases are left un-investigated. We previously described a novel approach to wildlife crime investigation that looked at the identification of human DNA on poached animal remains (Tobe, Govan and Welch, 2011). Human DNA was successfully isolated and amplified from simulated poaching incidents, however a low template protocol was required which made this method unsuitable for use in many laboratories. We now report on an optimised recovery and amplification protocol which removes the need for low template analysis.Samples from 10 deer (40 samples total — one from each leg) analysed in the original study were re-analysed in the current study with an additional 11 deer samples. Four samples analysed using Chelex did not show any results and a new method was devised whereby the available DNA was concentrated. By combining the DNA extracts from all tapings of the same deer remains followed by concentration, the recovered quantity of human DNA was found to be 29.5 pg ± 43.2 pg, 31 × greater than the previous study. The use of the Investigator Decaplex SE (QIAGEN) STR kit provided better results in the form of more complete profiles than did the AmpF?STR® SGM Plus® kit at 30 cycles (Applied Biosystems). Re-analysis of the samples from the initial study using the new, optimised protocol resulted in an average increase of 18% of recovered alleles. Over 17 samples, 71% of the samples analysed using the optimised protocol showed sufficient amplification for comparison to a reference profile and gave match probabilities ranging from 7.7690 × 10^? 05 to 2.2706 × 10^? 14.The removal of low template analysis means this optimised method provides evidence of high probative value and is suitable for immediate use in forensic laboratories. All methods and techniques used are standard and are compatible with current SOPs. As no high cost non-human DNA analysis is required the overall process is no more expensive than the investigation of other volume crime samples. The technique is suitable for immediate use in poaching incidents.     

Marital cruelty: reconsidering lay attitudes in England,c. 1580 to 1850

The mid-eighteenth century is seen as a turning point after which English legal and lay attitudes to cruelty expanded from life-threatening violence to include a wider range of behaviours. This article reconsiders this chronology of changing ideas about marital cruelty. It follows the lead of recent scholarship that challenges the thesis of a ‘civilising’ process in attitudes towards state-violence and inter-personal violence and draws on new conclusions about marital relationships, spouses' gendered roles, and early modern manhood, which complicate simplistic views of patriarchal unions. Focusing upon the full array of acts – not just life-threatening ones – discussed in cruelty cases from c. 1580 onwards, this article questions the convention that social toleration for husbands' use of violence against their wives declined from the 1750s as part of an overall civilising process.
