In formaldehyde treated tissues, fluorescent compounds are formed. We could demonstrate, that these compounds result from a reaction of biogenic amines such as beta-phenylethylamines or beta-(3 indolyl) ethylamines with formaldehyde to yield the fluorescent 3,4 dihydroisoquinolines or 3,4 dihydro-beta-carbolines.
Several homicides characterized by peculiarities related to the occupation of the perpetrator are reported and compared with observations from literature. Common characteristics of the cases are determined by the following factors: availability of the equipment (i.e. drugs, poisons, tools) and application of special knowledge, skills or techniques provided by professional education (i.e. pharmacology, injection and dissection techniques in physicians and related professions, use of extraordinary, self-constructed weapons by technicians). Remarkable features of some cases are the long period of meticulous preparation and professional attempts to abolish or disguise suspicious findings. Thus, these homicides often present with uncommon modes of commitment and unusual forensic findings which are difficult to recognize and assess. Supplementing own experience by the cases reported in literature is an indispensable prerequisite to examine these cases properly and to provide professional and competent expert opinion for the police authorities.
