OCI is a division of the department of Auditor-Controller and is comprised of investigators with fiscal, technology and personnel backgrounds.  OCI investigators are codified under Penal Code (PC) Section 830.13 and are Peace Officers Standards and Training level III certified.

OCI is responsible for coordinating and conducting criminal and administrative investigations of alleged fraud and misconduct by County managers, employees, contractors and vendors.  OCI also conducts studies of and advises client departments on fiscal, physical and data security.

OCI investigators are "fact gatherers".  We utilize financial tools, interview techniques, monitoring and computer forensics in conducting investigations to effectively address the complaints filed.  Investigators also prepare and issue search warrants and testify in Court and Civil Service.
