Empirical evidence for AMBER alert as crime control theater: a comparison of student and community samples

While the AMBER Alert system is intended to facilitate the rescue of abducted children, it has practical and psychological limitations. Participants indicated their emotions and perceptions about Alerts before and after reading a vignette that manipulated details about a child abduction. Results indicate that the Alert system fits some criteria of Crime Control Theater (CCT). CCT polices are emotion-based legal actions that appear to address crime but fail to do so and have unintended consequences. Participants experienced panic about child abduction and believed the system is an effective tool which should be used no matter the unintended consequences. Emotions and panic positively related to perceptions of the system. Still, perceptions were not particularly positive, indicating that some participants recognize the system's limitations. Female and community participants generally had more positive perceptions than males and students, especially when experiencing high emotions or panic. Reading about an abduction reduced emotions overall and led to more positive perceptions (but only in the ‘AMBER Alert success’ condition). Reading about an ‘Alert failure’ did not affect perceptions. Results highlight the role of emotion in shaping perceptions of the system. As with other CCT policies, lawmakers should rely less on community sentiment and more on science when adopting legislation.     

Changes in illicit cocaine hydrochloride processing identified and revealed through multivariate analysis of cocaine signature data

For nearly 30 years, the methods utilized in illicit cocaine hydrochloride production have remained relatively consistent. Cocaine hydrochloride is typically produced one kilogram at a time. As a result, each individual kilogram is unique and distinct from other kilograms in any particular seizure based on the total alkaloid profile, occluded solvent profile, and isotopic signature. Additionally, multi-kilogram cocaine seizures are often comprised of cocaine from several different coca growing regions. There has been a documented shift in this type of processing based on the recent analysis of a large cocaine seizure in the Eastern Pacific. Signature analyses of samples from 21 kg randomly selected from a 517 kg seizure were virtually identical. Triplicate analyses of each sample via gas chromatography with flame ionization detection, static headspace gas chromatography mass spectrometry, and isotope ratio mass spectrometry were completed. An initial outlier evaluation of the data and an in-depth univariate analysis indicated there was no statistically significant difference among the 21 samples at the 95% confidence interval. Principal components analysis did reveal consistent minor deviations between the samples and known authentic data from the Nariño coca growing region of Colombia. These deviations were only observed on the latter principal components and could be explained by differences in solvent selection during cocaine hydrochloride processing. Chemical analyses in addition to a thorough statistical evaluation suggest a shift in the traditional small-batch method of cocaine processing to a multi-kilogram, high throughput approach.     

Barriers to services for rural and urban survivors of rape

A significant proportion of survivors of rape do not utilize formal services to cope with the aftermath of rape. Understanding victimization experiences in environments that differ on resources, such as rural versus urban areas, may be an important dimension to consider in understanding barriers. Thirty women (18 rural and 12 urban) were recruited from rape crisis centers to participate in focus groups. Study results suggest that (a) survivors of rape experience many barriers to service utilization, (b) there were some differences in barriers to service utilization that were mentioned only in rural areas and some that were mentioned only in urban areas that may suggest that community context is important to consider in understanding barriers to service use, and (c) barriers to health and mental health services overlap with barriers to criminal justice system services.     

Frozen: Thawing and Its Effect on the Postmortem Microbiome in Two Pediatric Cases,

Previous postmortem microbiome studies have focused on characterizing taxa turnover during an undisturbed decomposition process. How coexisting conditions (e.g., frozen, buried, burned) affect the human microbiome at the time of discovery is less well understood. Microbiome data were collected from two pediatric cases at the Wayne County Medical Examiner in Michigan. The bodies were found frozen, hidden in a freezer for an extended time. Microbial communities were sampled from six external anatomic locations at three time points during the thawing process, prior to autopsy. The 16S rRNA V4 gene amplicon region was sequenced using high‐throughput sequencing (Illumina MiSeq). Microbial diversity increased, and there was a distinct shift in microbial community structure and abundance throughout the thawing process. Overall, these data demonstrate that the postmortem human microbiome changes during the thawing process, and have important forensic implications when bodies have been substantially altered, modified, and concealed after death.
