Final answer:
The statement correctly describes livor mortis or postmortem lividity, which manifests as purplish discoloration in the lowest parts of a body after death, aiding in determining post-mortem movement. It is TRUE.
Step-by-step explanation:
The statement provided relates to the phenomenon known as livor mortis or postmortem lividity, which is a sign observed in the early stage of death. When blood no longer circulates, it begins to settle in the lowest parts of the body due to gravity. This gives the skin a purplish, blanching color. If pressure is applied to these areas, such as by contact with the ground or another surface, the blood can be pushed aside, leaving pale spots. This condition helps forensic investigators determine post-mortem movement. It starts to appear typically within 30 minutes to 2 hours after death and becomes fixed, meaning it won't shift, after about 12 hours. The provided statement describes these occurrences in an accurate manner and hence is TRUE.
