Mayhem in the Morgue | In the Water, No One Can Hear You Sweat

Some drowning cases only begin to make sense after forensic pathology reveals what was happening inside the body before death. In this episode of Mayhem in the Morgue, Chief Medical Examiner Dr. Kendall Crowns explains how forensic pathologists use vitreous fluid from the eye to detect dangerous electrolyte imbalances like hyponatremia after death, then he shares two memorable cases that show how something as ordinary and necessary as water can become deadly under the wrong circumstances. It is a sobering look at how heat, exertion, overhydration, and underlying mental and physical illness can intersect in ways most people never expect.
