Senior Investigator, AOI (260004Y4)
About the Office of the Inspector General (OIG or Office)
The Massachusetts OIG is an independent state agency charged with preventing and detecting fraud, waste, and abuse in the use of public funds and property. The OIG has broad oversight of how state and local governments use federal, state and local funds and property.
The Office is led by the Inspector General of the Commonwealth, appointed by the Governor, Attorney General and Auditor. The OIG is organized into three bureaus:
Specialty & General Government, Legal & Compliance, and Operations, Training & Publications. The bureaus focus on specific agencies, issues, or functions. See the Office of the Inspector General (OIG) for more information about the OIG.
The Legal and Compliance Bureau is managed by the General Counsel. This bureau consists of three divisions:
The Office of the General Counsel;
Audit, Oversight and Investigations; and Government Outreach and Public Policy. The Office of the General Counsel provides legal support across the office related to human resources, procurements, compliance, litigation and investigations. The Audit, Oversight and Investigations Division investigates possible fraud, waste and abuse of public resources across state and local government. The Government Outreach and Public Policy Division oversees the OIG’s government outreach, municipal engagement, and policy and legislative initiatives and is responsible for legislative mandates such as the review of land dispositions.
The Audit, Oversight & Investigation Division (AOI) investigates allegations of fraud, waste and abuse of public resources across state and local government, excluding agencies covered by another OIG Division. The division often works closely with other agencies, municipalities, law enforcement state and federal prosecutors. AOI may be investigating claims of public corruption or other wrongdoing in a number of public sectors, such as education, energy, housing, public administration, public construction, public safety, public works and social services.
AOI also investigates and reports on the misuse of public funds, even when no crime or civil action is involved.
An important source of information comes from the public through the OIG’s confidential, 24-hour hotline for reporting fraud, waste and abuse of public funds and property. These complaints can develop into full investigations or are redirected to the appropriate agency if it falls outside our jurisdiction.
