Mission Statement​

The mission of the Sheriff's Office Investigative Services Division is to provide follow-up investigation of criminal activity, solve crimes, enable prosecution of criminals, recover property losses and restore justice in our communities in a professional, efficient, and compassionate manner.

The Investigative Services Division operates out of three primary locations:  Headquarters, West Valley Station, and South County Station.  To accomplish the mission of the Investigative Services Division, investigators are trained for general investigation and receive additional training for specific areas of expertise.  In order to ensure that each crime is properly investigated by a detective with skill and experience, the following units are each dedicated to a particular type of crime.

  • Homicide / Major Crimes Unit:  Investigates all murders, manslaughters (non-traffic related), questionable deaths, mayhem, elder physical abuse, significant assaults and robberies.
