The case report of a serial killer who worked at several hospitals as a respiratory therapist is presented. The suspect was initially labeled a benevolent Angel of Death who ended the suffering of elderly patients through mercy killing. However, his subsequently declared motive for homicide was very different from other similar cases in medical settings. The application of new analysis techniques for the detection of pancuronium bromide in a series of aged exhumation tissues gave positive results and led to the resultant conviction of the therapist. 相似文献

A rapid, sensitive, accurate, precise, reproducible, and versatile method for determining the purity of reference drug standards and the routine analysis of illicit drugs and adulterants using proton (1H) Nuclear Magnetic Resonance (NMR) Spectroscopy is presented. The methodology uses a weighed sample dissolved in a deuterated solvent or solvent mixture containing a high purity internal standard. The NMR experiment employs 8 scans using a 45 second delay and 90 degrees pulse. In the determination of purity of reference standards, the number of quantitative determinations available is equal to the number of peak groups that are baseline resolved. The relative standard deviation (RSD) of these signals is usually < 1% for pure standards, and the results agree well with other purity determining methods. This method can also aid in the determination of correct molecular weight for standards containing an unknown number of waters of hydration or an unknown number of acids per drug in salts. Because the molar response for the hydrogen nucleus is 1 for all compounds, and since no separation media are used, only one linearity study is required to test a probe. In the presented study, the linearity of the NMR probe was determined using methamphetamine HCl dissolved in deuterium oxide (D2O) with maleic acid as the internal standard (5 mg) for a range of concentrations from 0.033 to 69.18 mg/ml with a resulting correlation coefficient of >0.9999 for all 6 methamphetamine peak groups. The spectra of complex illicit heroin, methamphetamine, MDMA, and cocaine samples are presented, as well as an extensive list of compounds, their solubilities and the solvent(s) and internal standard used. 相似文献

After 20 months of interment in a deep grave, the decomposed body of the 81-year old testator of a will was exhumed to sustain the burden of proof that he lacked testamentary capacity when the will was rewritten two days prior to his death. The brain was mushy and pulverized with complete disappearance of the brainstem, cerebellum and subcortical ganglia. Small foci of relatively intact dorsal frontal neocortex were identified. Sections from these foci were stained with hematoxylin and eosin, bielchowsky silver stain and immunostains for beta amyloid peptide (betaA4), tau and alpha-synuclein. Despite severe autolysis and decomposition, the bielchowsky stain and the betaA4 immunostains showed preserved frequent neuritic amyloid plaques with very few residual neurofibrillary tangles. Cerebral Amyloid Angiopathy was present. At the present time this case represents the first documented and reported case of direct tissue diagnosis of Alzheimer's Disease pathology in a decomposed brain following long term burial in a deep grave. 相似文献

Both Holmes and Langdell believed that science was the model for all human inquiry and the source of all human progress. Langdell was influenced by an unsophisticated scientism, which led him to attempt to identify the true meaning of legal doctrines. Holmes was influenced by the sophisticated positivism of John Stuart Mill, which led him to attempt to reduce legal rules and doctrines to scientific laws of antecedence and consequence, justified only by their social consequences. Both Holmes and Langdell concluded that judges ought to decide a case by applying the rules established by precedent, without appeal to any special claims of justice and without appeal to any higher-order normative principle. 相似文献

The number of criminal defendants in cases filed in the federal courts increased by fewer than 1,000 from 1990 to 1995. Separate analyses of filings of felony and misdemeanor defendants revealed that there are different factors that influence the magnitude of the caseload of each offense level. The number of federal felony filings is strongly linked to staffing levels within the ninety-four U.S. attorneys’ offices, while the types of filings are a reflection of prosecution priorities. As a result, the magnitude of the felony caseload in the federal courts does not mirror either local or national crime rates. Misdemeanor filings, on the other hand, are dependent on enforcement practices of local authorities at military bases and/or national parks, and are concentrated within a few federal courts. The number of misdemeanor filings and traffic violations, in particular, are susceptible to dramatic changes when these local authorities modify their enforcement procedures. 相似文献

The purpose of this study was to determine the applicability of Bowlby's attachment theory in predicting male-to-female relationship violence. One-hundred-forty-nine heterosexual couples were interviewed regarding their childhood attachment experiences, current adult attachment status, stress level and current relationship history (including past violence). Results indicated that attachment factors were unique predictors of male violence toward a female intimate. Additionally, female partners of violent males were significantly more likely to have insecure adult attachment styles. The data provide some evidence for the role of attachment processes in explaining domestic violence. The findings underscore the importance of early determinants of intimate aggression, focusing on the basic attachment relationship. 相似文献
