Major Frauds Section

SECTION OVERVIEW

The Major Frauds Section investigates and prosecutes some of the most significant white-collar crime cases in the country. The Section is comprised of experienced federal prosecutors, and is nationally recognized not only for the size and sophistication of the cases it handles, but for the breadth of its caseload.

In the area of corporate and securities fraud, the Major Frauds Section has successfully prosecuted significant cases involving corporate embezzlement, securities and accounting fraud, insider trading, and stock manipulation. The Section also prosecutes a wide range of investor frauds, including international mass marketing frauds, Ponzi schemes, boiler rooms, loan modification schemes, and identity theft rings. The cases brought by the Section frequently involve losses to victims totaling tens, if not hundreds, of millions of dollars.

In addition to the cases it brings involving frauds against private individuals and entities, the Major Frauds Section handles a broad array of highly significant cases involving fraud against the government. The section dedicates significant resources to attacking health care fraud, including in particular fraud directed at Medicare and Medi-Cal, and has successfully prosecuted major cases involving hospitals, doctors, home health agencies, diagnostic testing facilities, medical clinics, hospice care providers, and durable medical equipment suppliers. The section also handles significant cases involving procurement fraud, government program fraud, bankruptcy fraud, and tax evasion. In addition, the section handles large dollar mortgage lending and foreclosure rescue frauds.

Members of the Major Frauds Section serve as coordinators and members of a number of task forces and working groups, including the Financial Fraud Enforcement Task Force, the Securities and Commodities Fraud Working Group, the Health Care Fraud Task Force, Operation Canadian Eagle/Project Emptor, the Financial Institution Fraud Task Force, the Bankruptcy Fraud Working Group, and the Identity Theft Task Force.

The Major Frauds Section works closely with investigators from the Federal Bureau of Investigation, Internal Revenue Service-Criminal Investigation, U.S. Postal Inspection Service, U.S. Secret Service, Securities and Exchange Commission, Federal Trade Commission, and Commodity Futures Trading Commission, as well as with Inspectors General from a wide number of government agencies.
