An Evidence‐Based Forensic Taxonomy of Windows Phone Communication Apps

Communication apps can be an important source of evidence in a forensic investigation (e.g., in the investigation of a drug trafficking or terrorism case where the communications apps were used by the accused persons during the transactions or planning activities). This study presents the first evidence‐based forensic taxonomy of Windows Phone communication apps, using an existing two‐dimensional Android forensic taxonomy as a baseline. Specifically, 30 Windows Phone communication apps, including Instant Messaging (IM) and Voice over IP (VoIP) apps, are examined. Artifacts extracted using physical acquisition are analyzed, and seven digital evidence objects of forensic interest are identified, namely: Call Log, Chats, Contacts, Locations, Installed Applications, SMSs and User Accounts. Findings from this study would help to facilitate timely and effective forensic investigations involving Windows Phone communication apps.     

Application of 3D Laser Scanner to Forensic Engineering

In the case of building collapses and overturned structures, a three‐dimensional (3D) collapse or overturn model is required to reconstruct the accident. As construction sites become increasingly complex and large, 3D laser scanning is sometimes the best tool to accurately document and store the site conditions. This case report presents one case of a structure collapse and one case of an overturned crane reconstructed by a 3D laser scanner. In the case of structural collapse of a prefabricated shoring system, a 3D model reconstructed all the members successfully, a task that is nearly impossible using a scale such as a tape measure. The reconstructed prefabricated shoring system was verified through a structural analysis through comparison with the construction drawings to investigate faults in construction. In the case of the overturned crane, the jib angle and other major dimensions were successfully acquired through 3D laser scanning and used to estimate the working radius. As a result, the propriety of the working radius with the given lifting load was successfully determined.     

Validation of Reduced Reagent Volumes in the Implementation of the Quantifiler® Trio Quantification Kit

The Quantifiler^® Trio Quantification Kit has been developed to quantify the total amount of amplifiable and human male DNA in samples and to estimate the extent of DNA degradation. To minimize the cost of DNA quantification, we evaluated kit performance using a reduced volume of reagents (1/10‐volume) using DNA samples of varying types and concentrations. Our results demonstrated concordance between the manufacturer's method and the low‐volume method for DNA quantification, DNA degradation index estimation, and human male DNA quantification. We confirmed the practical utility of the low‐volume method with 109 casework samples by evaluating short tandem repeat (STR) profiling success with respect to DNA quantity and quality. We also defined a cutoff value for DNA quantity to ensure reliable STR results. Using a reduced volume of reagents, 10 times more reactions per kit are possible; accordingly, this method reduces the cost of DNA quantification, while maintaining performance.     

Suicide by Medication Overdose in Prison: A Study of Three Cases

Suicide is one of the principal causes of mortality in a prison environment. Although suicide by medication overdose is less frequent than suicide by hanging, self‐strangulation, or vein cutting, it raises questions as to how the medications are obtained, particularly in view of the specific organization of the medication circuit in prisons. We present three cases of suicide by medication overdose involving different therapeutic classes with different distribution circuits and review the regulatory requirements and the measures that could be taken to prevent such suicides.     

Survival of Atherosclerotic Calcifications in Skeletonized Material: Forensic and Pathological Implications

Atherosclerosis is a chronic inflammatory disease creating calcifying plaques in the arterial walls. Because its paleopathological diagnosis remains little studied on skeletal remains, its impact on forensic and archeological data is completely underestimated. Here, 24 skeletal remains from the Milano Cemetery Skeletal Collection have been studied to evaluate the chance of atherosclerotic calcification survival, retrieval, and identification. Through direct comparison with a known autopsy collection and literature, the identification and categorization of several types of calcifications were performed. Clothing elements such as tights or socks played a definitive role in the preservation of the calcifications; hence they are more likely to be found in forensic cases than in archeological ones. Therefore, vascular calcifications are possible to collect and identify in skeletal remains if sufficient care is given to their recovery. Consequently and as markers of the disease, such identification can provide valuable pathological information for forensic and archeological cases.     

An Improved Protection for the (Mentally Ill) Trans Parent: A Queer Reading of AP,Garçon and Nicot v France

The European Court of Human Rights has been deciding cases concerning LGBT rights since the early 1980s. Its case law on trans rights has changed drastically over time, imposing upon the states of the Council of Europe certain minimum standards regarding the legal recognition of gender identity. In its recent judgment of April 2017 the Court laid down a new rule to be adopted by domestic legislation; namely, that the legal recognition of gender transition cannot be made conditional upon pursuing medical or surgical procedures which have (or are likely to have) sterilising effects. This article analyses the judgment from a critical perspective grounded in queer theory, noting both the positive and the negative elements of the Court's decision.     

Promoting Stability for Youth Returning from Residential Care: Attorney Perspectives

Aftercare services have been suggested to improve reintegration for youth departing residential care programs. The purpose of this study was to collect views from legal professionals about the challenges youth and families face during reintegration and solutions to improve stability. Views were collected from 14 legal professionals (e.g., guardian ad litem, legal counsel) through a survey and 90‐minute nominal group technique focus group. Results indicated parent expectations about re‐entry and lack of services, supports and resources were challenges. Solutions suggested by participants included family, mental health and educational supports, and transition planning. Study limitations and future implications are discussed.     

Complex Suicide by Self‐stabbing and Drowning: A Case Report and a Review of Literature

Sharp force injuries and drowning are methods exceptionally combined in complex suicides. We report a challenging case of complex suicide by self‐stabbing and drowning that illustrates the difficulty in discriminating between homicide and suicide in such circumstances of death. The corpse of a young man was found submerged in a river, stabbed nine times with two wounds that had penetrated the thorax and had caused lung injuries and a hemopneumothorax. The postmortem and histological examinations were consistent with a death caused by drowning, but the manner of death still remained undetermined. Police investigation finally concluded to a suicide, although no suicide note had been left and the victim had no underlying diagnosed mental disorder. The parameters that may help distinguish suicide from homicide at the autopsy should be interpreted in light of a thorough forensic investigation to determine the exact manner of death in such a case.     

Death From Butane Inhalation Abuse in Teenagers: Two New Case Studies and Review of the Literature

The ready availability of butane makes butane abuse frequent. Fatalities are rare. This study presents two cases of death by butane overdose. The postmortem analyses were carried out using headspace gas chromatography–mass spectrometry. It revealed femoral blood butane concentrations of 18 and 22 mg/L, respectively, as well as specific combinations of adjuvants in each victim. In one of the victims, brain and fatty tissue also contained butane, pointing to chronic consumption. The originality of this study is to show that the identification of specific combinations of adjuvants can be helpful for identifying the brand of deodorant used. Also, sampling the skin and mucosa can help identify the method of drug delivery. The histological examination documented both the direct toxic effect of the gas on the respiratory mucosa and signs of chronic abuse. Volatile substance intoxications should be systematically considered in case of sudden death in a teenager.     

Child Fatalities in Dammam: A Call for Child Fatality Reviews in Arab Countries

Identifying children's risk exposure is the first step toward mortality prevention. This retrospective study determined the causes of child fatalities in Dammam, Saudi Arabia. Death reports of children and adolescents from 1999 to 2015 (N = 157) were analyzed. Boys represented most cases (69%) and there were two age peaks (1–5 years and 16–18 years). Accidents (typically immersion) defined the main death circumstance (51%) followed by homicide (25%). Only 33% of cases underwent autopsy, and the most common cause of death was head injury (27%) followed by firearm injury. Only one immersion death underwent autopsy. This study revealed important data about the risk exposure of children in Dammam and emphasizes deficient investigative procedures. Child fatality reviews comprise systematic data collection by multidisciplinary teams to determine the true risks toward children in a community. Such teams do not exist in Arab countries; therefore, strategies should be implemented to initiate them.
