Unusual finding in a water-logged corpse--hyperchylomicronemia or pulmonary fat embolism?

During excavation work at the bank of the River Inn the corpse of a 32-year-old alcoholic male was recovered. Head injuries suggested a crime of violence. Postmortem examination demonstrated conspicuous milky turbidity of the blood, which was found by laboratory testing to be due to hyperchylomicronemia. The findings are interpreted and their relevance to the determination of postmortal head injuries is discussed. The inadequacy of double-edged knife specimens and frozen-section biopsies for the estimation of pulmonary fat embolism as a vital reaction is considered.
