Participants in the Madoff investment scandal included employees of Bernard Madoff's investment firm with specific knowledge of the Ponzi scheme, a three-person accounting firm that assembled his reports, and a network of feeder funds that invested their clients' money with Madoff while collecting significant fees. Madoff avoided most direct financial scrutiny by accepting investments only through these feeder funds, while obtaining false auditing statements for his firm. The liquidation trustee of Madoff's firm has implicated managers of the feeder funds for ignoring signs of Madoff's deception.
