The eldest son of disgraced fraudster Bernard Madoff has been found dead after committing suicide at his New York home.
Mark Madoff, who was 46, was found hanged on Saturday. The New York City medical examiner has ruled his death a suicide.
After his father was arrested in 2008, Mr Madoff claimed not to have known anything about the multi-million dollar Ponzi scheme.
However criminal investigators have continued to explore the possibility that he and other family members, including younger brother Andrew, were involved.
Both brothers worked for Madoff Securities; Mark had been there for more than 20 years when the firm collapsed, causing more than 13,000 people to lose money.
Madoff Sr is now serving a 150 year prison sentence for cheating charities, celebrities and long-time investors.
Mr Madoff died on the second anniversary of his father’s arrest. He is survived by his wife and two-year-old son.
