[Definition of a "domestic-setting corpse"--a retrospective study of 211 discoveries].

In Germany, the term "domestic-setting corpse" is regularly used both in the medicolegal field (daily work, specialist literature) and by the general public (press, novels). The only formal definition of the term is in the German-language textbook "Basiswissen Rechtsmedizin" (Madea and Dettmeyer 2007). In this retrospective study, we compared the criteria for this definition with our findings. Autopsy reports from the Institute of Forensic Medicine at the Justus Liebig University in Giessen, Germany, for the period between 2005 and 2011 (including February), were reviewed retropectively to see if the criteria for this formal definition could be found. We chose a postmortem interval of more than 24 hours and discovery of the corpse in a private home as inclusion criteria for our study (n = 211). We could verify four of the criteria for the definition ("advanced signs of decomposition", "reclusiveness", "unclear cause of death", "difficult to identify") in our study. One criterion ("frequently a long postmortem interval") was too vague to be of use, and two further criteria ("discovery circumstances" and "high frequency of active alcohol dependence") could only be partially confirmed. In almost half of our cases there were, however, signs of general substance abuse. The proportion of male "domestic-setting corpses" was distinctly higher than that of females (approx. 3:1). The average age-at-death was 50.1 years for men, and 57.8 years for women, and thus clearly below the average life expectancies. In over half of the cases - even those with explicitly mentioned advanced facial decay--the identification method had not been noted. In the formal definition, the criteria "discovery circumstances" and "alcoholism" thus need to be more precisely defined. Also, due to the inexplicit time range, the criterion "frequently a long postmortem interval" was too vague to be applied to, or compared with, our cases as a classic criterion. We suggest specifying a minimum postmortem interval of 24 hours for "domestic-setting corpses". In addition, more attention should be paid to the identification of "domestic-setting corpses". To date, investigation authorities frequently seem to assume that a corpse discovered in a private residence is that of the home owner or occupant.
