Criminal professional body packers and harmless "swallowers"

Body packing practices used by professional drug smugglers are sometimes imitated. However, both groups can develop the same clinical symptoms induced by body packing. The paper describes four cases of criminal professional body packers and two cases of "swallowers" not regarded as criminals who required medical treatment. The authors discuss the necessity of an abdominal X-ray and show how the increasingly professional methods used by body packers make a reliable diagnosis more difficult.     

Application of 3D documentation and geometric reconstruction methods in traffic accident analysis: with high resolution surface scanning, radiological MSCT/MRI scanning and real data based animation

The examination of traffic accidents is daily routine in forensic medicine. An important question in the analysis of the victims of traffic accidents, for example in collisions between motor vehicles and pedestrians or cyclists, is the situation of the impact. Apart from forensic medical examinations (external examination and autopsy), three-dimensional technologies and methods are gaining importance in forensic investigations. Besides the post-mortem multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) for the documentation and analysis of internal findings, highly precise 3D surface scanning is employed for the documentation of the external body findings and of injury-inflicting instruments. The correlation of injuries of the body to the injury-inflicting object and the accident mechanism are of great importance. The applied methods include documentation of the external and internal body and the involved vehicles and inflicting tools as well as the analysis of the acquired data. The body surface and the accident vehicles with their damages were digitized by 3D surface scanning. For the internal findings of the body, post-mortem MSCT and MRI were used. The analysis included the processing of the obtained data to 3D models, determination of the driving direction of the vehicle, correlation of injuries to the vehicle damages, geometric determination of the impact situation and evaluation of further findings of the accident. In the following article, the benefits of the 3D documentation and computer-assisted, drawn-to-scale 3D comparisons of the relevant injuries with the damages to the vehicle in the analysis of the course of accidents, especially with regard to the impact situation, are shown on two examined cases.     

Operator Exposure to Scatter Radiation from a Portable Hand-held Dental Radiation Emitting Device (Aribex™ NOMAD™) While Making 915 Intraoral Dental Radiographs*

Abstract: Operator exposure to backscatter radiation while using an Aribex™ NOMAD™ radiation emitting device (a portable, self-contained, cordless, hand-held dental X-ray unit) was determined while the operator employed various typical and atypical use scenarios during the exposure of 715 digital and/or film-based dental radiographs and 200 study control exposures. Study data was compared to the radiation safety occupational exposure annual Maximum Permissive Dose (MPD) of 50 mSv (5000 mrem) to determine the possible exposure risk to an unprotected operator using this device. The results showed the reproductive organs received the highest dose and the thyroid the least. The average operator whole body dose for the study was determined to be 0.047 mSv (4.47 mrem) or 0.09% of the annual MPD. Extrapolating the data as an expression of averaged annual operator exposure resulted in a whole body dose of 0.4536 mSv (45.36 mrem) or 0.9% of the annual MPD, These results are well below established occupation exposure limits and are compatible with those published by the manufacturer.     

Natural Law and Normative Inclinations

Natural law ethics holds that practical rationality consists in engaging in non‐defective ways with a range of fundamental goods. These basic goods are characteristically presented as reflecting the natural properties of humans, but the details of this picture vary widely. This article argues that natural law ethics can usefully be understood as a type of dispositional theory of value, which identifies the basic goods with those objectives that humans are characteristically disposed to pursue and value for their own sake. Natural law theories of practical rationality can then be understood as attempts to capture the principles that would govern engagement with the basic goods under ideal conditions. The article begins by offering an account of normative inclinations as human dispositions both to act in certain ways and to believe that the actions are worthwhile or required. It then explores the implications of this account for natural law ethics, discussing the role of the basic goods in practical rationality, whether the goods may change over time and the connection between the goods and human nature.     

A cocaine body packer with normal abdominal plain radiograms. Value of drug detection in urine and contrast study of the bowel

Drug packets are usually detected by ordinary abdominal radiographs, which is of major importance in the apprehension and prosecution of drug body packers, but false negatives may occur. We report the case of a cocaine body packer who had used the prograde route and in whom the initial abdominal plain films were normal. The diagnosis of cocaine body packing was assessed by seldom-described complementary methods of detection, including drug detection in the urine and contrast study of the bowel.     

The value of examination aids in victim identification: a retrospective study of an airplane crash in Nepal in 2002

After the crash of an airplane in Nepal in the year 2002, the dental status of the 14 European victims was examined at autopsy as well as after additional removal of the soft tissue and compared with antemortem findings which were available in 11 cases. Re-examination of all jaws showed that nine composite fillings and seven root fillings as well as one parapulpal pin could not be detected during autopsy. Because tooth-coloured restorations may be overseen even by an experienced expert, the findings underline the necessity of performing a full resection of both jaws and removal of the soft tissue. Furthermore, X-ray analysis of the jaws and the use of phosphoric acid or ultra violet radiation for recognizing tooth-coloured restorations are recommended.

Bill of Sale Lending: Reforming a ‘Toxic’ Form of Credit

The Bills of Sale Acts were enacted in Victorian times as a form of secured credit whereby ‘goods’ owned by a borrower could be assigned under the bill of sale to a lender who would have title to the goods transferred to him. The lender would then allow the borrower to retain possession of the goods in exchange for instalment payments with interest. In the twenty‐first century these bills are most commonly used as ‘logbook loans’ for vehicles with extortionate interest rates and very little protection for individual consumers. This article examines the operational background to the Bill of Sale Acts. It focuses upon particular concerns for consumers and businesses and provides critique of the registration process before examining the proposals and consultations for reform currently before the Law Commission.     

Adjustment, Stabilisation and the Analysis of the Employment Structure in Turkey: An Input- Output Approach

The aim of the paper is to examine the effects on employment of the large-scale structural adjustment programme undertaken by Turkey from the early 1980s onwards. In this respect, we particularly analyse how appropriate the choices of factor intensity after structural adjustment programme have been in the domestic production in comparison with the availability of domestic factor endowment. Our findings show that foreign trade in intermediate goods creates extra use of domestic labour, which can be considered as the labour cost of importing intermediate goods. This is the case in the majority of industries in the pre- and post-liberalisation period in Turkey. However, the capacity of using extra labour as a result of importing intermediate goods appeared to have decreased in the post-liberalisation period.     

The risk of body packing: a case of a fatal cocaine overdose

The process of swallowing or inserting illegal packets of drugs for the purpose of evading law enforcement officers carries risks other than criminal charges. It can be fatal. Individuals engaged in such activities are called "Body Packers" or "Mules". The most frequent cause of the death among body packers is acute drug intoxication due to rupture of the package(s) within the gastrointestinal tract. We present the first documented case of a body packer that died from cocaine intoxication following the rupture of packets of cocaine in Western Pennsylvania.

Lessons Learned from Autopsying an Unidentified Body with Iodine‐125 Seeds Implanted for Prostate Brachytherapy

We report here lessons learned from an autopsy case involving radioactive materials. We performed an autopsy of an unidentified mummified man with no available medical history whom from imaging findings we suspected had received radioactive seed implants for prostate brachytherapy. We returned the excised prostate and seeds to the body. A few days later, the body was identified by DNA matching and cremated. According to the man's medical record, he had undergone iodine‐125 seeds implantation for prostate cancer 11 months earlier. We should have removed the radioactive seeds from the body to prevent radiation exposure to the bereaved family and/or environmental pollution due to cremation. Surprisingly, one seed was found in the stored prostate specimen. Forensic experts should be cognizant of the risk of both radiation exposure in the autopsy room and environmental pollution. We must remain abreast of the latest advances in medicine.     

Virtopsy-postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) in a fatal scuba diving incident

The body of a 44-year-old scuba diver was examined using postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI), and findings were verified by subsequent autopsy. The goal was to find out whether the important pathomorphological findings for the reconstruction of events and the identification of cause and manner of death could be identified using modem digital cross-sectioning techniques. The findings of a massive vital decompression with pulmonary barotrauma and lethal gas embolism were identified in the radiological images. MSCT and MRI were superior to autopsy in the demonstration of the extent and distribution of gas accumulation in intraparenchymal blood vessels of internal organs as well as in areas of the body inaccessible by standard autopsy.     

Inactivation of human immunodeficiency virus (HIV) by ionizing radiation in body fluids and serological evidence

A method to use ionizing radiation to inactivate HIV (Human Immunodeficiency Virus) in human body fluids was studied in an effort to reduce the risk of accidental infection to forensic science laboratory workers. Experiments conducted indicate that an X-ray absorbed dose of 25 krad was required to completely inactivate HIV. This does not alter forensically important constituents such as enzymes and proteins in body fluids. This method of inactivation of HIV cannot be used on body fluids which will be subjected to deoxyribonucleic acid (DNA) typing.     

The consequences of potentially differing distributions of the refractive indices of glass fragments from control and recovered sources

In forensic cases involving glass evidence, the variance of the recovered glass refractive index (RI) has been observed to be larger than the variance of the control glass RI. This has consequences for subsequent interpretation. To investigate this phenomenon, a study was made of the probable distributions of refractive indices of the recovered glass given a range of casework type scenarios involving breakage and backscatter. An investigation of the consequences of any distribution differences with regard to casework was also made. It was discovered that the inclusion of surface fragments from the float surface of the glass can have a profound effect on the comparison of recovered and control glass samples. The effect was largest when a breaker was striking the float surface of a window. In particular, it was found that the inclusion of a few surface fragments even post grouping is sufficient by itself to explain the observed differences in variance of RI between control and recovered groups. Surface fragments, if present, are very likely to be treated as outliers and to be deemed as non-matching. The findings of this paper challenge routine glass examination procedure and suggest that knowledge of which surface is facing the striker is valuable information in interpretation.     

Getting in touch--3D printing in forensic imaging

With the increasing use of medical imaging in forensics, as well as the technological advances in rapid prototyping, we suggest combining these techniques to generate displays of forensic findings. We used computed tomography (CT), CT angiography, magnetic resonance imaging (MRI) and surface scanning with photogrammetry in conjunction with segmentation techniques to generate 3D polygon meshes. Based on these data sets, a 3D printer created colored models of the anatomical structures. Using this technique, we could create models of bone fractures, vessels, cardiac infarctions, ruptured organs as well as bitemark wounds. The final models are anatomically accurate, fully colored representations of bones, vessels and soft tissue, and they demonstrate radiologically visible pathologies. The models are more easily understood by laypersons than volume rendering or 2D reconstructions. Therefore, they are suitable for presentations in courtrooms and for educational purposes.     

Temperature variations in a parked vehicle

There were two reasons why this work was conducted. The first was to help determine the time of death of suicide and homicide victims inside vehicles. The second was to investigate the serious threat to life of children or pets left in stationary vehicles on a hot summers day. This paper demonstrates that when a vehicle is parked in the sun, temperature levels in the cabin of the vehicle can be more than 20°C above the ambient temperature. A simple 'greenhouse' model for predicting the daily internal vehicle temperatures, using readily available local meteorological data, was developed. This statistical model was calibrated using meteorological data and temperature data collected on parked vehicles over several summer seasons. The model uses environmental temperature and radiation data as input, and is shown to predict cabin temperatures to within about 1°C. Both the data collected and the model developed show that the temperature inside the cabin of a black vehicle is typically 5°C higher than that inside a white vehicle on a hot summer day. Also lowering the driver's window of the vehicle by 2.5 cm typically reduces cabin temperatures by about 3°C, which is not sufficient to reduce significantly the safety concerns for children or pets left in parked vehicles.     

The thin blue line meets the big blue sky: perceptions of police legitimacy and public attitudes towards aerial drones

Police departments across the United States are now integrating new visual monitoring technology (e.g. unmanned aerial vehicles [UAVs or ‘drones’], body cameras) into routine police practices. Despite their potential use in multiple areas of proactive and reactive policing, public attitudes toward police use of UAVs, and visual monitoring technology overall, is mixed. As an extension of previous research, the current study uses a national survey to assess how well individuals’ perceptions about police legitimacy, effectiveness, and other criminal justice attitudes predict the level of public receptivity and opposition toward police UAV use in various contexts. The implications of these findings for public policy and law enforcement practices are discussed.     

Prolonged Electro-muscular Incapacitation in a Porcine Model Causes Spinal Injury

Conducted electrical weapons are designed to cause temporary electro-muscular incapacitation (EMI) without significant injury. The objective of this study was to assess the risk and cause of spinal injury due to exposure to a benchtop EMI device. Porcine subjects were exposed to 19 and 40 Hz electrical stimuli for a prolonged duration of 30 sec. X-ray imaging, necropsy, and accelerometry found that lumbosacral spinal fractures occurred in at least 89% of all subjects, regardless of the stimulus group, and were likely caused by musculoskeletal fatigue-related stress in the lumbosacral spine. Spinal fractures occurred in the porcine model at an unusually high rate compared to human. This may be due to both the prolonged duration of electrical stimulation and significant musculoskeletal differences between humans and pigs, which suggests that the porcine model is not a good model of EMI-induced spinal fracture in humans.
