About OCI

Who We Are

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 have completed the PC 832 Peace Officer Standards and Training Course.


What We Do

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.


How We Do It

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.
