Homicide Investigations 1.0

Homicide Investigations 1.0 

Each year in the U.S. there are approximately 16,000 homicides reported, and probably another ±4,000 that are not reported, or are mis-categorized. Most homicide investigations start with the arrival of the first officer at the scene. Yet, few officers are trained in the actual conduct of a homicide investigation. This course addresses some of the basic elements officers need to understand regarding homicide investigations, including the collection and protection of vital evidence, the types of homicides, and ultimately, determining causes and time of death.
