Question: how long does it take for a body to putrefy?
Answer: 3–4 days: The discoloration spreads and discolored veins become visible. 5–6 days: The abdomen swells noticeably and the skin blisters. 10–20 days: Black putrefaction occurs, which is when noxious odors are released from the body and the parts of the body undergo a black discoloration.
