We present a case of an accidental autoerotic death involving the inhalation of a propane-butane gas mixture, also known as LPG (liquefied petroleum gas). A 19-year-old male was found dead in supine position in his bed in a residential accommodation one day after he was last seen alive. On a personal computer at the end of the bed, a pornographic movie was still running. On his left shoulder, an empty rubber balloon and on the bedside 2 empty "Kisag-Gas" cartridges were found. Toxicologic investigations revealed an intoxication with propane and butane, together with a recent consumption of cannabis. This case report compares the toxicologic findings with other recently published cases, and the theories of the toxic effects are discussed. 相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years. 相似文献

The present study tested the proposition that disengagement of moral self-sanctions enables prison personnel to carry out the death penalty. Three subgroups of personnel in penitentiaries located in three Southern states were assessed in terms of eight mechanisms of moral disengagement. The personnel included the execution teams that carry out the executions; the support teams that provide solace and emotional support to the families of the victims and the condemned inmate; and prison guards who have no involvement in the execution process. The executioners exhibited the highest level of moral, social, and economic justifications, disavowal of personal responsibility, and dehumanization. The support teams that provide the more humane services disavowed moral disengagement, as did the noninvolved guards but to a lesser degree than the support teams. 相似文献

Experimental data useful for the interpretation of paint evidence recovered during burglary cases were obtained. A population study was carried out on 41 blue crowbars seized on suspects in Switzerland and 37 blue paints traces found at burglary scenes. Paint traces were also searched on the blades of 207 crowbars seized by the police in Switzerland and 24 white traces were analysed: these paints were analysed using infrared spectroscopy (FTIR) in order to estimate relative frequencies of each paint type. Simulated contacts were carried out between crowbars and painted wood in order to study the phenomenon of transfer and to evaluate the amount of paint transferred: a total of 198 simulations were carried out including individual, successive and cross transfer. The paint properties such as the chemical composition and its age influenced the amount of paint transferred. Cross transfer from the tool paint to the wood and vice versa was regularly observed. Moreover, secondary transfer of paint coming from the preceding wooden surfaces was also systematically observed: this could establish links between several burglary scenes and a suspected tool. A scenario of a burglary case involving the cross transfer between tool and household paints is proposed as a numerical example: the evaluation of such case was formalised using likelihood ratios based on the experimental data obtained. 相似文献

The accumulation of 2,4-dichlorophenoxyacetic acid (2,4-D) and its metabolite 2,4-dichlorophenol (2,4-DCP) in the kidneys of rats was investigated. Male and female Sprague-Dawley rats were given 2,4-D in drinking water and food for 30 days. Group A (control group) was fed a normal diet, Group B was fed 50 ppm 2,4-D in 15 g food, Group C received 100 ppm 2,4-D in 15 g food, Group D received 25 ppm 2,4-D in 15 ml drinking water and Group E was given 50 ppm 2,4-D in 15 ml of drinking water. Levels of 2,4-D and 2,4-DCP in kidneys were determined using high performance liquid chromatography (HPLC). It was observed that at low doses of 2,4-D, the metabolite, 2,4-DCP found in the kidneys. 相似文献

National Crime Survey (NCS) data yield an estimate that 171,000 Americans were nonfatally shot in criminal assaults, robberies, and rapes for the period 1973–1979. Comparing this estimate with the number of firearms homicides during this period suggests either that the death rate in gunshot cases is very high (over 1/3) or that the NCS estimate is low. Based on police-generated data appropriate to estimating the true death rate from gunshot wounds, it appears that the NCS estimate is low by a factor of about 3.0 compared with the number of criminal gunshot woundings known to the police. It is common knowledge that survey-based estimates of assault rates tend to be relatively unreliable, a fact that has been attributed to problems with respondents being willing and able to recall threats, fist fights, and other minor assaults. The current result indicates that the estimation problem is not limited to minor assaults. There is reason to think that the underestimate of gunshot woundings is the result of problems with the NCS sample as well as problems with respondent cooperation. 相似文献
