Immunohistochemical analysis of forensic evidence from a double homicide

We report the use of immunohistochemical staining for analysis of forensic evidence from a double homicide. A 38-year-old woman and her 7-year-old daughter were murdered by multiple blows to the head and face with a tomahawk, resulting in multiple fragments of brain tissue scattered about the murder scene. The victims' husband and father was the main suspect, who maintained that he was out of town on business during the evening of the murders. However, a shirt taken from the suspect's car on the morning after the murders (secured by the police before the suspect visited the murder scene) was found to have two small stains. DNA analysis on the stains showed the presence of the deceased wife's DNA, and immunohistochemical stains on shirt fragments conclusively documented the presence of deep central nervous system tissue, providing the critical piece of evidence needed to arrest and prosecute the suspect. This report demonstrates that shirt or similar cloth fragments can be processed into paraffin blocks and subsequently immunostained to search for and classify types of tissue fragments that may be present on the fabric.     

The Eyeball Killer: Serial Killings with Postmortem Globe Enucleation

Although serial killings are relatively rare, they can be the cause of a great deal of anxiety while the killer remains at‐large. Despite the fact that the motivations for serial killings are typically quite complex, the psychological analysis of a serial killer can provide valuable insight into how and why certain individuals become serial killers. Such knowledge may be instrumental in preventing future serial killings or in solving ongoing cases. In certain serial killings, the various incidents have a variety of similar features. Identification of similarities between separate homicidal incidents is necessary to recognize that a serial killer may be actively killing. In this report, the authors present a group of serial killings involving three prostitutes who were shot to death over a 3‐month period. Scene and autopsy findings, including the unusual finding of postmortem enucleation of the eyes, led investigators to recognize the serial nature of the homicides.     

Convict Criminology and the Struggle for Inclusion

Convict Criminology (CC) began in the early 1990s as a reaction to the then current state of academic criminology that did not adequately reflect the voices of convicted felons. Since its beginnings, CC has attempted to draw attention to a range of problems created by the criminal justice apparatus and defenders of the status quo. Dr. Joanne Belknap’s 2014 ASC presidential address and subsequent article presented an argument that stressed the importance of activism to be considered as part of criminological research. In the process, she reviewed her career and then criticized the field of Critical Criminology, in particular Convict Criminology. The article, however, ignored the numerous efforts that CC has engaged in to build an inclusive group school, movement, organization and network that includes the diverse voices of Ph.D. educated convicts and excons, and overall reflected a superficial understanding of the history and intent of Convict Criminology. This article attempts to explain the shortcomings of Belknap’s article and clarifies misunderstandings.     

Assessing the impact of stricter alcohol advertising standards: the case of Beam Global Spirits

Reducing youth exposure to alcohol advertising is a global health priority. In most countries around the world, the alcohol industry is given the opportunity to regulate itself with respect to advertising practices. Generally, the alcohol industry self‐regulations are lax, allowing youth to be disproportionately exposed to alcohol advertising. However, Beam Global Spirits and Wine (Beam) voluntarily adopted more restrictive advertising standards in the United States in 2007. This study assessed Beam's compliance with their new standard and estimates its effect on youth exposure and advertising costs. We found that Beam's compliance with its more restrictive standards was imperfect, but never‐the‐less, we estimated that youth exposure to alcohol advertising was reduced compared to other spirits brands. Beam's more restrictive standards did not increase their advertising costs, and therefore other alcohol companies should consider adopting similar standards around the world.

Validation of the barcoding gene COI for use in forensic genetic species identification

The application of forensics to wildlife crime investigation routinely involves genetic species identification based on DNA sequence similarity. This work can be hindered by a lack of authenticated reference DNA sequence data resulting in weak matches between evidence and reference samples. The introduction of DNA barcoding has highlighted the expanding use of the mtDNA gene, cytochrome c oxidase I (COI), as a genetic marker for species identification. Here, we assess the COI gene for use in forensic analysis following published human validation guidelines. Validation experiments investigated reproducibility, heteroplasmy, mixed DNA, DNA template concentration, chemical treatments, substrate variation, environmental conditions and thermocycling parameters. Sequence similarity searches using both GenBank BLASTn and BOLD search engines indicated that the COI gene consistently identifies species where authenticated reference sequence data exists. Where misidentification occurred the cause was attributable to either erroneous reference sequences from published data, or lack of primer specificity. Although amplification failure was observed under certain sample treatments, there was no evidence of environmentally induced sequence mutation in those sequences that were generated. A simulated case study compared the performance of COI and cytochrome b mtDNA genes. Findings are discussed in relation to the utility of the COI gene in forensic species identification.     

Unexpected Human Fatality Associated with Bed Bug (Hemiptera: Cimicidae) Heat Treatment

Thermal insect treatments can be an effective method of controlling cryptic insect pests, particularly bed bugs, in residential settings. The treatments require high heat over a sustained timeframe. Residents are not present during treatment but return after completion. An unexpected death was investigated following heat treatment for bed bugs in the home of an elderly female, found with a postmortem axillary temperature of 106.2°F (41.2°C) approximately 8 h after returning home. The cause of death was classified as hyperthermia with a contributory cause of hypertensive cardiovascular disease. The manner of death was an accident. The decedent had medical history and medications that could have impaired her ability to dissipate heat. Furthermore, the air conditioning inside the residence was not functional following treatment. Recommendations including education regarding heat stroke and treatment, re‐entry timeframes, and/or temperature thresholds are suggested to reduce the risk of heat‐related injury or death in vulnerable populations.     

Social capital in Scottish and Danish neighbourhoods: paradoxes of a police–community nexus at the front line

Community-oriented social capital strategies and punitive-oriented policing approaches conflict. Establishing local networking initiatives with community-oriented policing at the centre lends itself to an assets-based policing approach, based on honouring, mobilizing and extending the assets of community members. Scholars argue about the need for comparative research on convergences and divergencies across subcultures on the streets and communities. Based on qualitative data gathered from working class communities in Scotland and Denmark in 2014, the article draws inspiration from community-generated theory of social capital to explore the micro-sociology of experiences and understandings about community–police integration policy initiatives. We use this perspective to argue that the building of positive inter-generational and police–community relationships is the result of social exchanges and officers’ use of what we call ‘constructive investment strategies’. Ironically, our insights from Scotland to Denmark also suggest what appear as positive achievements of community policing may instead intensify residents’ negative perceptions of police officers and organizations. In this way, the article illuminates the tangled and conflicted nature of these embedded symbolic interactions, social capital formations and the latter’s form as a potential positional and ‘tribal’ commodity.
