How long after death does Livor Mortis typically begin?

• A. 1-6 hours
• B. 30mins - 2hrs
• C. 6-12 hours
• D. 12-24 hours

Answer: (B)

Livor mortis, or lividity, occurs after circulation stops as blood settles by gravity into dependent tissues. This process typically begins fairly quickly, usually within about 30 minutes to 2 hours after death, rising as a visible reddish-purple discoloration in the parts of the body that are lowest. This timing is crucial for estimating time since death and for detecting if the body has been moved before the lividity fixed. By roughly 6–12 hours, the livor mortis tends to become fixed, meaning it won’t shift if the body is repositioned. So the onset window of 30 minutes to 2 hours is the best match.
