This article examines the correlation between weather features and homicide in. Baltimore, Maryland, over an 8-year span of time. The consistent meteorological-measure of importance is the number of previous days in a row in which the discomfort index (a temperature and humidity measure) has been over the physiologically relevant level of 79. In all cases, however, the variance explained is quite small. The results are used to compare physiological and interactional explanations of weather or heat effects, leading to the conclusion that the repertoire of habits and adaptations available to the individual conditions his or her reactions to physiological stress induced by the weather. 相似文献

Five homicides are described that had remained unexplained as to the causes of death after gross pathology. Although general signs of asphyxiation were present, they were lacking injuries specific of strangulation or oro-nasal occlusion. The diagnoses of asphyxiation were established by microscopical investigation of the lung and confirmed by subsequent police inquiries. An oro-nasal occlusion was involved in three cases, a strangulation or an oro-nasal occlusion, in another case. The victims were young and healthy. Toxicological investigations remained negative in four cases; one victim was anaesthetized by bromazepam and ether and had a blood alcohol concentration of 80 mg/100 ml. Lung histology and electron microscopy revealed acute emphysema, the development of a haemorrhagic-dysoric syndrome and a microembolism syndrome. With regard to the haemorrhagic-dysoric syndrome, the development of alveolar-interstitial edema is particularly important. This finding may also be diagnosed by light microscopy in semi-thin sections. It is emphasized that the combined action of several pathomechanisms is responsible for the rapid manifestation of the pulmonary lesions. Especially, the haemorrhagic-dysoric syndrome is brought about by the combined action of inspiratory intrapulmonary vacuum and raised intracapillary pressure. The complex pattern allows to compile the diagnosis of mechanical asphyxia even if there is no corresponding injury. 相似文献

Extent, trends, and perpetrators of prostitution-related homicide in the United States 总被引:1,自引:0,他引:1

Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide. 相似文献

The authors report on a case of postmortem washing of a body with bleach. An adult female victim was found nude in an alleyway with both hands removed in the City of Westminster, CO. Cause of death was attributed to severe blunt force trauma to the head. The victim had been dumped in the alleyway within 7 h of discovery. Evidence discovered at the crime scene and autopsy indicated that the murder and subsequent washing of the body with bleach occurred at a secondary location(s). The victim was wet to the touch, presenting a strong odor of bleach. Several "ribbon"-like burn patterns were observed on the victim's back and upper thighs. These burn marks were replicated by dowsing a deceased pig with an over-the-counter concentration of bleach. 相似文献

An Assessment of the Quality of Homicide Data in the Supplementary Homicide Reports: A Research Note
《Justice Quarterly》2012,29(4):711-731
The Federal Bureau of Investigation (FBI)’s Supplementary Homicide Reports (SHR) is a national-level incident-based data clearinghouse for homicide events in the USA used in countless research studies to track homicide trends, test theory, and analyze policy. Despite its wide use, the SHR has well-known limitations. This research note examines the accuracy of the information in the SHR by comparing homicide cases in Newark, New Jersey with their respective data to determine the level of disagreement between the data sources, which variables exhibit the greatest disagreement, and the case-related variables related to the disagreement. Uniquely, we do this for cases where offenders are known in the SHR. Our findings suggest that variables such as victim-offender relationship and circumstance have high disagreement even when the SHR reports an offender, and that the most important covariate of this is time to close the homicide investigation with an arrest. Research implications of the results are discussed. 相似文献

Research in many forensic science fields commonly uses domestic pigs (Sus spp.) as proxies for human remains, due to their physiological and anatomical similarities, as well as being more readily available. Unfortunately, previous research, especially that which compares the decompositional process, has shown that pigs are not appropriate proxies for humans. To date, there has not been any published research that specifically addresses whether domestic pigs are adequate human proxies for the geophysical detection of clandestine graves. As such, the aim of this paper was to compare the geophysical responses of pig cadavers and human donor graves, in order to determine if pigs can indeed be used as adequate human proxies. To accomplish this, ground penetrating radar (GPR) and electrical resistivity tomography (ERT) responses on single and multiple pig cadaver graves were compared to single and multiple human donor graves, all of which are in known locations within the same geological environment. The results showed that under field conditions, both GPR and ERT were successful at observing human and pig burials, with no obvious differences between the detected geophysical responses. The results also showed that there were no differences in the geophysical responses of those who were clothed and unclothed. The similarity of the responses may reflect that the geophysical techniques can detect graves despite what their contents are. The study implications suggest that experimental studies in other soil and climate conditions can be easily replicated, benefiting law enforcement with missing persons cases. 相似文献

植物DNA检验技术是利用植物遗传性状的稳态性对关联植物物证进行检验鉴定的手段。将该技术应用于现场重建,应基于植物物证与犯罪嫌疑人、被害人及其活动环境具有"重大关联性"。从命案现场重建的需求上看,应围绕犯罪嫌疑人及其可控物品中附着植物与现场植物的种属同一性判断、被害人尸体(尸块或尸骸)及其随附物品中附着植物与中心现场植物的种属同一性判断、疑似侵害物及其附着植物与嫌疑人行为关联植物的种属同一性判断等三个角度或层次进行检验和综合分析。植物DNA检验技术可阐明物证的时空运行停顿规律,为命案现场重建工作提供一种参考性解决方案。 相似文献
