Rates vary with surrounding temperature and conditions: Temp Cooler environment = faster heat loss Windy = faster heat loss Body fat = slower heat loss Clothing = slower heat loss Time of death determined by temperature calculations is expressed as a range of time since it cannot be calculated exactly.
Cell autolysis begins following death. Green and purplish staining occurs from blood decomposition. Skin takes on a marbled appearance. d) Face becomes discolored.
Butyric Fermentation: Corpse begins to dry out Most of flesh is gone Dry Decay: Corpse is almost dry Further decay is very slow from lack of moisture
