Identification of mechanical asphyxiation in cases of attempted masking of the homicide

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.     

A case of sudden cardiac death in connection with Salmonella typhimurium infection

A case of fatal myocarditis in a 24-year-old otherwise healthy man is described. It was possible to cultivate Salmonella typhimurium from the alimentary tract, the blood, the liver and skeletal muscles. The possibility of a solitary myocarditis with fatal outcome due to Salmonella typhimurium infection is discussed. Such a case seems not to have been mentioned previously in the literature.The problems concerning the statistical registration of such a death are briefly discussed.     

Psychologists as consultants for changes of venue the use of public opinion surveys

This study reports the use of public opinion surveys to support motions to change venue. Step-bystep procedures of venue surveys are outlined, and results of their use in five capital murder trials are presented. Employing a quasi-experimental approach to the surveys allows inferences, about the likelihood of obtaining between-county differences of certain magnitudes. In addition, the use of a survey instrument with standardized subparts permits a second, novel type of contrast: comparisons previous cases. The responsiveness of this approach to the typical criticisms of venue surveys is discussed.     

Congressional campaign effects on candidate recognition and evaluation

To date, most congressional scholars have relied upon a standard model of American electoral behavior developed in the presidential setting. This research extends our knowledge of Congressmen's incumbency advantages and their sources. Candidate preference is viewed as a function of the relative recognition and evaluation of incumbents and their challengers, as well as of Democrats and Republicans. In the recognition model, contact with voters and media effects are quite important, but there is no direct role for party identification. Evaluation is a function of personal contact and party identification, and media variables are insignificant. Relative recognition, relative evaluation, and party identification are three important predictors of candidate preference, and incumbency itself adds little beyond what is contained in incumbent recognition and evaluation advantages.An earlier version of this paper was presented at the 1980 annual meeting of the Western Political Science Association, San Francisco, March 1980.
