What are common signs of drowning observed in a victim?

The presence of foam, pale skin, and conjunctival petechiae are indeed common signs associated with drowning victims.

Foam can develop in the airways and around the mouth and nostrils of a drowning victim due to the mixing of water and air, which is indicative of drowning. Pale skin is often a result of hypoxia, where the body is deprived of adequate oxygen due to submersion in water. Conjunctival petechiae, or small red or purple spots on the conjunctiva, occur due to increased pressure in the blood vessels during drowning and are a notable sign of trauma or asphyxia.

This combination of signs provides crucial information about the circumstances of the death, which is particularly relevant during a forensic investigation into drowning cases. Understanding these signs can help medical death investigators form a clearer picture of what might have transpired prior to the individual's death. Other options may include various symptoms that are not directly associated with drowning or lack the specificity needed to indicate drowning accurately.
