This presentation covers the basic concepts of clandestine grave discovery, control, and excavation. Particular attention will be placed on the practical recovery techniques and how to keep the context from becoming disturbed. The lecture will then transition into the investigation of deaths that occur in water. Deaths in the water, whether at home or on a lake, etc., are generally thought of as accidents. A major focus of this lecture is to move all investigators into the mindset that any death should be thought of as a homicide until evidence to the contrary is uncovered. A fluid crime scene is very difficult to search and to control. General search techniques will be covered so that the investigator will understand what the dive team is doing underwater.
