The Madoff investigation in the public record begins after the confession to family, not as a successful pre-collapse detection. Agents took a statement, the SEC froze the firm, and a trustee took the books.
Later work was forensic accounting and civil recovery: subpoenas, bank records, and adversary proceedings. This page describes those after-the-fact steps, not any method of concealment.
Agencies
- Federal Bureau of Investigation — Arrested Madoff on 11 December 2008 and supported the U.S. Attorney’s criminal case in the Southern District of New York.
- U.S. Securities and Exchange Commission — Filed the emergency civil action, later settled related enforcement matters, and commissioned the inspector-general review of prior examinations.
- U.S. Attorney, Southern District of New York — Charged Madoff and later defendants; took the 2009 plea and tried or resolved employee and related cases.
- SIPA trustee (Picard) — Liquidated the broker-dealer estate, sued recipients of transfers, and distributed recoveries to allowed customers under bankruptcy-court supervision.
What followed
- Family report
After Madoff’s admission to his sons, counsel notified federal authorities on 10 December 2008.
- Arrest
FBI agents arrested Madoff at his apartment on 11 December 2008 and began seizing firm records.
- Emergency civil relief
The SEC obtained a freeze and the appointment of a receiver, soon succeeded by the SIPA process.
- Plea negotiations
Prosecutors and defense reached an eleven-count plea entered on 12 March 2009, avoiding a guilt-phase trial.
- Sentencing record
Victim letters and government submissions went to Judge Chin before the 29 June 2009 hearing.
- Civil reconstruction
Picard’s team matched statements to bank flows and filed hundreds of adversary actions to recover transfers.
Turning points
- The December 2008 admission — Without the confession to family and the prompt report to authorities, the firm might have lingered days or weeks longer; the public investigation starts from that report.
- The 2009 OIG report — The inspector-general file shifted part of the story from a single defendant to a documented pattern of missed examinations.
- Large SIPA settlements — Bank and feeder settlements in the 2010s turned a theoretically enormous hole into a measurable recovery rate on allowed principal.
Investigators after December 2008 were reconstructing a completed collapse. The unsolved piece is why earlier official looks did not stop the advisory book — a question the OIG already answered in part.
