Animal Scavenging and Scattering and the Implications for Documenting the Deaths of Undocumented Border Crossers in the Sonoran Desert,

Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border.     

Contribution of Antemortem Computed Tomography Findings to Cause of Death Determination: An Unusual Fatal Stroke

In the case reported here, the antemortem computed tomography scan (CT scan) was essential in the forensic investigation. A 32‐year‐old man was found fully awake with a facial abrasion, after what seemed to be a car accident. He lost consciousness suddenly one hour after initial management. Successive CT scan showed a facial fracture and a metallic foreign body in the carotid canal associated with an occlusion/dissection of the left internal carotid, a pseudoaneurysm, and a carotid‐cavernous fistula. The victim died from a stroke. Autopsy confirmed that the facial abrasion was a gunshot entrance wound, the metallic foreign body being a projectile. Intracranial vascular injuries linked with gunshot wounds are most of the time isolated and due to pelet embolism. The observed vascular injury association has never been described in the existing literature. The CT scan provided a better understanding of the chronology of events that led to death.     

An Accelerated Analytical Process for the Development of STR Profiles for Casework Samples

Significant efforts are being devoted to the development of methods enabling rapid generation of short tandem repeat (STR) profiles in order to reduce turnaround times for the delivery of human identification results from biological evidence. Some of the proposed solutions are still costly and low throughput. This study describes the optimization of an analytical process enabling the generation of complete STR profiles (single‐source or mixed profiles) for human identification in approximately 5 h. This accelerated process uses currently available reagents and standard laboratory equipment. It includes a 30‐min lysis step, a 27‐min DNA extraction using the Promega Maxwell^®16 System, DNA quantification in <1 h using the Qiagen Investigator^® Quantiplex HYres kit, fast amplification (<26 min) of the loci included in AmpF?STR^® Identifiler^®, and analysis of the profiles on the 3500‐series Genetic Analyzer. This combination of fast individual steps produces high‐quality profiling results and offers a cost‐effective alternative approach to rapid DNA analysis.     

For fear of popular politics? Public attention and the delegation of authority to the United States executive branch

Legislators are thought to delegate policymaking authority to administrative actors either to avoid blame for controversial policy or to secure policy outcomes. This study tests these competing perspectives and establishes that public attention to policymaking is a powerful predictor of the extent to which significant United States statutes delegate authority to the executive branch. Consistent with the policy‐concerns perspective, by one calculation statutes dealing with high‐attention issues entail 48 percent fewer delegating provisions than statutes dealing with low‐attention issues – a far stronger relationship than is typically found in the delegation literature. As per the blame‐avoidance perspective, a number of additional analyses yield results consistent with the notion that fears about future public attention motivate statutory delegation if legislative conflict is sufficiently great. Overall, however, the results suggest that conflict typically is not sufficiently great and that legislators are generally more inclined to limit statutory delegation when the public is paying attention.
