Available at: www.ojp.gov.- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
