Bernie Madoff's son Mark was found dead of an apparent suicide Saturday in his New York apartment, following stepped up fraud victim lawsuit filings in recent weeks. The death occured two years to the day that Bernie was arrested,

NEW YORK — For two years, the two sons of jailed financier Bernard Madoff portrayed themselves as honest whistleblowers of their father's historic fraud. A court-appointed trustee depicted them as bungling money managers who did nothing to protect investors.

The suicide of Mark Madoff leaves unanswered questions for investors seeking payback for the billions of dollars his father siphoned — and for criminal investigators who continued to pursue charging Madoff's family for knowing participation in the fraud.

The 46-year-old Madoff — Bernard Madoff's eldest son — hanged himself Saturday by a dog leash on a metal ceiling beam in his Manhattan loft apartment, his 2-year-old son asleep in another room. The death was officially ruled a suicide by hanging Sunday by the city medical examiner.
