Mark Madoff, the elder son of convicted swindler Bernard Madoff, was found hanged in his New York City apartment in an apparent suicide, police said on Saturday.
"He was found hanged in his apartment. It was an apparent suicide," New York City police spokesman Paul Browne said.
Mark Madoff, 46, was found dead on the two-year anniversary of the arrest of his father. Bernard Madoff is now serving a 150-year prison sentence after confessing to running a decades-long Ponzi scheme that bilked investors out of millions.
Mark Madoff and his brother Andrew Madoff both had worked for their father's financial firm, Bernard L. Madoff Investment Securities LLC. They and other family members have been sued by a court-appointed trustee who is trying to recover money for defrauded investors.
Madoff family members have dismissed the allegations as baseless and said they were unaware of the fraud. None has been charged with any criminal wrongdoing.
The Wall Street Journal reported in February that the sons and brother of Bernard Madoff were the subject of criminal tax-fraud cases by federal prosecutors in Manhattan. No charges have been brought.
