Investigative Services

Investigations

The Investigations Section is part of the Operations Division of the Sheriff’s Office.  The section consists of fourteen full-time detectives, a crime analyst, one sergeant and one lieutenant.  The Investigations Unit puts in the long hours investigating the most complex crimes, keeping the patrol deputies available to respond to calls for service. 

Investigators specialize in a variety of assignments, including: Property Crimes, Elder Abuse, Financial Crimes, High Technology Crimes, Sexual Assault, Persons Crimes, Homicide, and Cold Case Crimes. 

These crimes are typically felony level crimes that may require a large amount of time and resources to solve. It is the highest priority of the Sheriff’s Office to uncover all evidence in order to bring closure to a case.

During large scale investigations or critical incidents, detectives come together as a unit for these complex events.  In order to better serve the community and victims of crimes, the Investigations Section works cooperatively with other law enforcement entities throughout the county, as well as other jurisdictions, and has many partnerships with government and community based organizations.
