How soon after death may marbling typically become visible?

Marbling becomes visible within 2-3 days after death due to a process called postmortem lividity, which is the pooling of blood in the lower parts of the body due to gravity after the heart stops beating. This hypostasis leads to discoloration of the skin as blood decomposes and the hemoglobin breaks down, showing a reddish-violet color. Over time, bacteria associated with decomposition can produce gases that contribute to the marbling appearance, characterized by a mottled pattern on the skin. The visibility of marbling typically does not occur immediately or within just a few hours after death, as these processes take time to develop fully. Additionally, within a week, the marbling will have advanced significantly, often accompanied by further decomposition changes, but the correct timing for initial visibility is primarily within the 2-3 day window.
