Murder by poisoning: successful analytical investigations of spectacular cases in Austria.

To prove murder by poisoning requires the application of analytical toxicology to detect the fatal substance and clear up the cause of death. Improvements in the development of mass spectrometry in combination with high-resolution chromatographic methods are steadily enhancing detection and identification power but making use of these advances relies on proper sample preparation as well as on knowledge about the chemical nature of the substances and their bio-transformation products. This review gives examples of case reports with successful analytical investigations of murder by poisoning in spectacular Austrian cases involving low molecular weight.

Quantitative determination of carbon monoxide in cell culture supernatants by spectrophotometric analysis.

A simple, sensitive, nonradioactive method for measuring carbon monoxide (CO) in cell culture supernatant is described. Dissolved CO reacts with hemoglobin (Hb) to carboxyhemoglobin (HbCO) in a modified Conway cell. HbCO is quantified by spectrophotometric analysis, and total concentration of CO given in microg CO/l cell culture supernatant is mathematically calculated.

Discovery of decomposed and mummified corpses in the domestic setting--a marker of social isolation?

Mass media reports attribute the occurrence of decomposed or mummified corpses in a domestic setting mainly to an increasing social isolation of elderly people. Not much is known about the demographic and medical conditions under which individuals are found months or even years after death in their homes. For this study, autopsy reports of individuals found dead and mummified or decomposed between 1993 and 1997 with those from 1963 to 1967 were retrospectively analyzed.
