How can you tell that someone is dead? Can you tell how long they’ve been dead?
Hours since death = 98.4°F – internal body temperature 1.5 The Process of Death Algor Mortis: Body cooling rate Livor Mortis: skin discoloration caused by pooling of blood Rigor Mortis: rigidity of skeletal muscles
1. Initial or fresh decay (autolysis) • The cadaver appears fresh externally but is decomposing internally due to the activities of bacteria present before death (0–4 days).
2. Putrefaction or bloating • The cadaver is swollen by gas produced internally, accompanied by the odor of decaying flesh (4–10 days).
3. Black putrefaction • Flesh of creamy consistency, with exposed body parts black. Body collapses as gases escape. Fluids drain from body. Odor of decay very strong (10–20 days).
4. Butyric fermentation Cadaver drying out. Some flesh remains at first; cheesy odor from butyric acid (20–50 days)
5. Dry decay • Cadaver almost dry; slow rate of decay. May mummify (50–365 days).
