The Criminal Investigations Division is responsible for investigating reported crimes, and identifying, locating, and apprehending the suspects.

All serious felonies (homicide, home invasion, robbery) are assigned to Major Crimes detectives.  The Special Victims Unit investigates reports of child abuse or neglect, and these detectives are specially trained to interview children.

Undercover officers in the Vice/Narcotics Unit work to eliminate illegal drug activities and apprehend street-level drug dealers and larger drug distributors.
