2–3 days: Staining begins on the abdomen. The body begins to swell, owing to gas formation.
3–4 days: The staining spreads and veins become discolored.
5–6 days: The abdomen swells with gas (produced by the bacteria that decompose the body), and the skin blisters.
2 weeks: The abdomen becomes very tight and swollen.
3 weeks: Tissues begin to soften. Organs and cavities are bursting. The nails fall off.
4 weeks: Soft tissues begin to liquefy, and the face becomes unrecognizable.
The exact rate of putrefaction is dependent upon many factors, such as weather, exposure and location.
